Definitions
- the present invention relates to a safety valve for a fuel supply. It is particularly suitable for being mounted on a built-in hob fitted with gas burners.
- the present invention also relates to a method for mounting the valve.
- the gases used as fuel to produce energy, and which form detonating mixtures with air under certain conditions, are dangerous and require the use of safety devices.
- valves for cooking appliances using gas burners in addition to a gas flow control valve, are equipped with such devices. These allow in particular to cut off the gas supply as soon as the gas is not burned in a burner.
- thermocouple placed in the burner, to control its correct operation and a safety shutter which allows, in the event of failure, to block any gas supply circuit of the burner.
- the heat of the flame causes a difference in electrical potential to appear in the thermocouple. This potential difference is used to activate an electromagnet which keeps the safety shutter pressed against a compressed spring; when the shutter is in the open position, that is to say that it does not prevent the circulation of gas in the supply circuit.
- the safety device is in the armed position, ready to perform its function.
- thermocouple in the event of a fault, for example if the gas is no longer burned in the burner, therefore in the vicinity of the thermocouple, the potential difference disappears, the electromagnet is no longer activated and the safety shutter is free to move under the impulse of the spring which drives it into the closed position to block the gas supply.
- the gas flow control valve is closed, i.e. it prevents the supply in burner gas, since no flame is likely to heat the thermocouple.
- a rotary knob is generally located above a housing of the hob. It allows by a rotary movement in a horizontal plane to adjust the opening of the valve, that is to say the desired gas flow.
- This button also allows, by a vertical movement from bottom to top, to arm the security device. It is a vertical control rod, fixed under the button or indirectly controlled by the button, which transmits the arming instruction, that is to say the movement from bottom to top, to the arming device.
- the safety and arming devices are generally included in the body of the tap and arranged in the supply circuit, which makes it possible to gain in compactness and to limit the number of gas seals between too many components of the supply.
- a housing of a built-in hob must be thin, generally thirty millimeters, to meet the standards of kitchen furniture manufacturers. Most valve components are therefore arranged horizontally inside the housing. This is the case of the shutter which moves horizontally under the opposing stresses of the arming device and the spring. The arming device must therefore make it possible to transform the vertical control movement of the control rod into a horizontal movement for the opening of the shutter.
- a first type of safety valve comprises an arming device, a part of which transmits the movement of vertical translation to a bent lever, articulated in rotation, which transforms the vertical movement into a horizontal movement.
- an arming device a part of which transmits the movement of vertical translation to a bent lever, articulated in rotation, which transforms the vertical movement into a horizontal movement.
- Such a device requires to precisely arrange several parts and their joints in the valve body. These layout operations cannot be carried out by automatic means but manually.
- the valve body is made in two parts, by molding or stamping, one to receive the parts and the other to serve as a cover for the first. A seal is also arranged between the two parts.
- Such a valve is expensive and its arming device is all the more fragile as it is complex.
- a second type of valve comprises an arming device which uses two ramps each mounted in translation, sliding one over the other, and whose slopes are arranged to transform the vertical movement of a ramp into a horizontal movement for the 'other.
- Such a device also has drawbacks. The precision of its realization and its assembly must be very important taking into account the short stroke for the ramps. Then, the support of one ramp on the other not being axial, it generates radial forces and wear in bearings for their guidance and the mutual friction of the ramps generates their mutual wear. This wear can cause the valve to malfunction.
- a European standard requires that a safety valve can perform at least 40,000 operations without failure. All the parts must therefore have at least good resistance to the friction to which they are subjected.
- the object of the invention is to provide a fuel supply valve comprising an arming device, simple to implement and reliable, for transforming the control movement, for example vertical, of a control rod into a arming movement, for example horizontal, for the safety device.
- a safety valve for a fuel supply equipped with a safety shutter, comprises a lever armament, mounted movable in rotation about a lever axis and characterized in that it comprises:
- - leading means for example a leading tongue, integral with the lever and extending substantially transversely to the lever axis, for driving said lever in rotation in response to an arming command
- - driven means for example a driven tongue, integral with the lever and extending substantially transversely to the lever axis, to push said shutter into a cocking position which allows the circulation of fuel in the supply.
- the tongues extend in respective directions substantially perpendicular to each other, they make it possible to transform a control movement into a perpendicular movement of arming and pushing.
- the lever axis will advantageously be arranged perpendicular to the directions of the control and thrust movements.
- the device will be included in a cavity of a fuel supply circuit, preferably preexisting, in a valve body. In order to minimize pressure drops during the circulation of fuel in the cavity, the cocking lever will have a reduced section. It can be made of folded sheet.
- the lever For use in a gas supply, the lever must be insensitive to a temperature of 150 degrees centigrade, which it can undergo either due to the proximity of the burner or due to the gas flow, i.e. that its behavior will not be affected by a temperature less than or equal to 150 degrees centigrade.
- the realization of the folded sheet lever guarantees a reduced section perpendicular to the direction of gas flow, that is to say transversely to the supply circuit. This section and the low pressure drops that it generates do not force the supply circuit to be oversized to allow the circulation of the gas mixture under satisfactory conditions. It can also be produced by other means than folding a sheet and having substantially the same shape, guaranteeing it a reduced section, measured perpendicular to the flow of the gas.
- the reduced section makes it possible to ensure a certain elasticity of the lever, in particular in torsion around an axis perpendicular to this section.
- This elasticity can be used for several purposes, in particular to maintain the preloaded lever between the cocking command and the shutter, so that the transmission of the command takes place without play and ensure fluidity in the command, therefore the comfort of the user.
- This elasticity also makes it possible to absorb certain manufacturing tolerances, therefore to reduce the cost of manufacturing the valve while ensuring that it operates safely.
- the folded stainless steel sheet ensures for the desired section, both the good hold of the lever and the desired elasticity.
- the lever can also be made of other materials which will ensure the same elasticity for sections compatible with the gas flow in the supply circuit.
- the cocking lever will include self-positioning means in the cavity and the shape of the cavity will be adapted to receive these self-positioning means.
- the cavity will for example include a bottom comprising self-centering means for a front end of the lever on a theoretical lever axis.
- An orifice opposite the bottom along the theoretical axis and opening outside the body of the valve will be used to introduce the lever into the cavity.
- the orifice will be closed by a closure plug comprising self-centering means for a rear end of the lever on the theoretical lever axis and ensuring a seal of the cavity with the outside.
- the lever To guarantee the position of the lever in the cavity when fitting the closure plug, provision can be made on the lever for pre-centering the lever in the cavity.
- These pre-centering means maintain the rear end of the lever in a position close to the theoretical axis, a position which allows it to cooperate with the self-centering means of the plug, during the installation of the latter, while the lever is no longer accessible from outside the valve body.
- This arrangement allows blind mounting of the lever in the cavity.
- the self-centering means of the bottom of the cavity and of the plug will serve as bearings for the rotation of the cocking lever, which aims to simplify the design and manufacture of the cocking device.
- FIG. 1 is a partial representation, in perspective and in section, of a possible configuration for a valve according to the invention whose safety device is in the closed position;
- - Figure 2 is a representation of the valve of Figure 1, the safety device is in the open position;
- - Figure 3 is a perspective view, on a larger scale, of an arming lever as used in the valve of Figures 1 and 2; and,
- FIG. 4 illustrates a method of mounting the lever of Figure 3 in a valve body according to the invention.
- Figures 1 and 2 show, in section and in perspective, a body 10 of a safety valve according to the invention, adapted to be mounted in a cooking plate using gas.
- the body comprises a safety device 20, mounted in a gas supply circuit.
- the safety device 20 is shown in the closed position in Figure 1, that is to say that it prohibits the circulation of gas in the supply circuit.
- the safety device 20 is shown in the open position in FIG. 2.
- the supply circuit successively comprises in the body 10 an intake duct 31 for the gas in an intake chamber 32, a safety orifice 33 at the intersection of the intake chamber and an intermediate cavity 34 , the intermediate cavity, a regulation chamber 35, a regulation orifice 36 and an outlet 37 for the gas to a burner not shown.
- the body 10 is cut into a profile section adapted to the shape of the body, that is to say that the profile is cut transversely into slices whose thickness is substantially that of the body.
- the supply circuit is created by making holes in the profile. The holes are intersecting two by two to ensure the continuity of the supply circuit. They are substantially cylindrical and they are blind, that is to say that they do not pass through the body.
- the holes have a primer orifice where the piercing was started on the profile and a bottom axially opposite the primer orifice, where the piercing was stopped. This bottom is at least constituted by a wall of a secant hole.
- the priming ports can be used as ports for the introduction of valve components into the supply circuit.
- the intake duct 31 has been shown opening vertically into the intake chamber 32.
- this duct is preferably horizontal. It brings the gas from a distribution manifold for the gas to each of the taps on the hob, up to the intake chamber.
- the safety device 20 is disposed in the intake chamber. It is therefore upstream in the supply circuit. It thus allows, by cutting off the circulation of gas downstream of the safety orifice if necessary, to optimize safety.
- the safety device consists of a substantially cylindrical housing 21 and of a piston 22 slidingly mounted, along an axis of revolution S of the housing 21, through one of the walls of the housing.
- the housing includes an electromagnet, not shown, which, when activated by the thermocouple, tends to cause the piston to penetrate inside the housing.
- the housing also contains a spring, not shown, which tends to extract the piston from the housing.
- One end of the piston 22, outside the housing, is provided with a shutter 23. If the electromagnet is not active, that is to say if the potential difference in the thermocouple is insufficient, the shutter 23 is maintained or brought into the closed position (see Figure 1) on the safety orifice 33 by the action of the spring. So there is no more communication for gas in the intake chamber with the supply circuit downstream of the safety orifice 33.
- thermocouple which supplies the electromagnet.
- a valve for regulating the gas flow by the tap is open and that the shutter is in the open position in order to allow the passage of the gas in the supply circuit, downstream of the safety orifice 33 and up to the burner.
- the safety device is armed, with the arming device, the shutter is therefore in the open position, that is to say that the gas in the intake chamber can penetrate through the orifice. 33 in the intermediate cavity 34, then beyond if the valve is open. If the gas is properly burned in the burner, the potential difference appears in the thermocouple under the action of the increasing temperature.
- the piston is kept retracted in the housing by the action of the electromagnet.
- the action of the arming device on the shutter becomes superfluous and can be released.
- the cocking device comprises a cocking lever 12, a spacer 13 and a control rod 14.
- the spacer 13 is arranged longitudinally through the security orifice 33. It has a shape suitable for guiding it on the periphery of the security orifice and for being able to slide there. It has a cross section which allows the circulation of gas in the orifice 33, between the intake chamber 32 and the intermediate cavity 34, when the shutter 23 is in the open position.
- the safety opening is cylindrical and the spacer has a star-shaped cross section with three branches 133. The branches are used to guide the spacer on the inner wall of the safety opening .
- the gas can circulate longitudinally between the branches of the star.
- the spacer extends longitudinally between two rounded ends 131, 132, the first 131 oriented towards the intermediate cavity 34 and the second 132 oriented towards the intake chamber 32.
- the spacer is made of reinforced plastic fibers which gives it significant resistance for a reduced section, at a lower cost than metal.
- the intake chamber, the safety orifice and the spacer are substantially coaxial with the axis S, shown in FIGS. 5 and 6, of the housing 21.
- the valve is used to regulate the gas flow in the burner, therefore to adjust the burner heating speed.
- a button 16 which makes it possible to actuate the rod 14, is accessible by an operator for controlling the tap.
- the rod substantially cylindrical with axis T, is arranged vertically.
- a valve not shown, allows by more or less obscuring the regulating orifice 36 to modify the gas flow rate in the burner.
- the operator can regulate the flow by printing at the button 16 a rotation R around a vertical axis, which has the effect of displacing the regulating valve in front of the regulating orifice 36, and therefore of concealing it more or less .
- the regulation chamber comprises sealing means, beyond the valve and below the control button 16, that is to say in the vicinity of the initiation orifice for the regulation chamber, around the rod. 14.
- the axis of rotation R of the button 16 is shown coinciding with the axis T of the rod 14.
- the button is generally not fixed on the rod 14, which it then only controls indirectly.
- the rod 14 can be arranged to only have a translational movement along the T axis.
- the axis of rotation of the button 16 can therefore be different from the T axis.
- the control lever 12 is made of thin stainless steel sheet. This sheet has been cut, folded and formed, to give it the shape more particularly shown in Figure 3.
- the lever is of substantially elongated shape, it comprises a beam 121 extending longitudinally between a front end 1 28 and a rear end 129.
- the beam 121 has a V-shaped section around a longitudinal fold 41 which ensures a certain rigidity of the beam in longitudinal bending.
- the ends 128, 129 of the beam 121 are cut in the form of points and between each of the points define an axis L for the lever.
- the lever axis L is substantially coincident with the longitudinal fold 41 of the beam 121.
- the cocking lever 12 further comprises a driving tongue 122 and a driven tongue 123.
- the driven tongue extends transversely from a longitudinal edge 42 of the beam, near the anterior end 128.
- the driven tongue 123 s' extends transversely from a longitudinal edge 43 of the beam, opposite the edge 42, near the rear end 129.
- Two fins 124 extend transversely, one from the edge 42, the other from the edge 43 , substantially in the extension of the V formed by the beam, one opposite the other, in the immediate vicinity of the rear end 129.
- the fins are pre-centering means for the rear end during mounting of the lever in the intermediate cavity.
- the lever is produced in series from a sheet metal strip.
- the intermediate cavity 34 (see FIG. 1) comprises a primer orifice which serves as an introduction orifice 341 for the lever 12 in the intermediate cavity and a bottom 343.
- the bottom comprises a coaxial cone 348 with the intermediate cavity. After introduction of the lever into the intermediate cavity 34, the latter is blocked by a plug 342, force-fitted into the initiation orifice 341 to seal the gas between the inside and the outside of the supply circuit.
- the plug 342 comprises a cone 349 which is substantially coaxial with the cavity 34, after the plug has been placed in the primer orifice 341.
- the cone 348 of the bottom and the 349 of the plug are respectively complementary to the anterior 128 and posterior 129 ends of the beam 121. They define respectively for each of the ends an anterior bearing 348 and a posterior bearing 349.
- the bearings define a theoretical axis of rotation for the lever 12 in the cavity 34 and serve as stops for the longitudinal positioning of the lever in the cavity 34. When the lever 12 is in place in the cavity 34, between the bearings 348.349, the theoretical axis is substantially coincident with the lever axis L.
- the tongues 122, 123 are arranged on the lever 12 so that, in a position of the lever in place in the cavity 34, the driving tongue 122 extends substantially diametrically to the regulation chamber 35 and in alignment with the regulation chamber, and so that the driven tongue 123 extends substantially diametrically to the safety orifice 33 and in alignment with said orifice and the inlet chamber 32.
- an operator pressure on the button 16 allows, by moving the plug 16, and the rod 14 which it drives in translation, vertically downward in direction A, parallel to the axis T, to arm the safety device 20.
- Return means for example a compression spring, make it possible to bring back r the rod 14 and the button 16, in a direction opposite to A, in a rest position.
- the control rod 14 is in its rest position, that is to say that it exerts no action on the arming device 1 1.
- the shutter 23 is in the closed position and no gas circulates in the supply circuit between the intake duct 31 and the outlet 37, independently of the occultation of the regulating orifice 36.
- the operator opens the tap, that is to say the valve occluding the regulating orifice 36 by a rotation R appropriate button 16 and pressed thereon to move the control rod in translation downward, vertically, along A.
- a lower end 141 of the rod 14 comes into contact with the driving tongue 122.
- a curved lower end will be provided.
- the axis T of the rod 14 is substantially perpendicular to the lever axis L, and the two axes are not intersecting.
- the driving tongue 122 is simultaneously driven downwards and the cocking lever 12, to which the driving tongue is linked in displacement, starts a rocking movement along B around the axis of lever L.
- the driven tongue 123 also linked in movement with the lever 12, is driven in the movement of the lever, in the direction of the safety orifice. During this tilting movement, the driven tongue is supported on the first convex end 131 of the spacer 13.
- the lever axis L and the axis S of the safety device are not intersecting and are substantially perpendicular.
- the spacer begins a horizontal translational movement which presses its second curved end against the shutter 23.
- the spacer 13 pushes the shutter 23 into an open position.
- a cocking lever as presented in the example has a certain elasticity in torsion around the lever axis L. This elasticity makes it possible to absorb an overtravel of the rod 14 along A, therefore an overtravel of the driving tongue according to B, while the safety device is already in abutment against the first abutment and the rod has not encountered the second abutment.
- the driving tongue 122 continues its travel along B, around the lever axis L, while the driven tongue 123 is substantially stationary.
- the overtravel as well absorbed makes it possible to mask dimensional differences and / or resulting clearances, either of methods and tolerances of manufacture of the valve, or of wear of the valve. Overtravel is therefore desirable and can be defined constructively.
- the elasticity of the lever will be provided to be compatible with this overtravel, that is to say to allow it to be fully absorbed.
- the cocking lever also plays, thanks to this overtravel, the role of shock absorber for the cocking device which ensures greater durability for the tap as well as greater comfort for the operator.
- the elasticity of the lever around the lever axis L is all the greater as the beam 121 has a significant slenderness.
- the safety device When the shutter is in the open position the safety device is in the arming position, that is to say that if gas circulates according to the arrows F, as illustrated in FIG. 2, in the supply duct up to At the burner, it is enough to ignite the gas, automatically or manually, to burn it and create in the thermocouple a sufficient potential difference to arm the device.
- the safety device Once the safety device is armed, the operator can release his pressure on the control button 16. The rod then resumes its rest position for which the arming device does not force the shutter to remain in the position of opening, that is to say that the arming device allows the shutter to move freely between its open and closed position. Thus, the device remains armed until it is requested to close, for example by cutting off the gas burner supply.
- the tongues are given a shape such that a force that one of them transmits to the 'one of the parts in translation is applied substantially along the axis of this part, for example on a vertex of a convex end of the part.
- the shape of the tongue is such that at a point of contact of the top with a contact surface of this tongue, the contact surface is always tangent to the curved end and perpendicular at this point to the axis of the part in translation.
- the tilting of the lever as described generates little friction and does not appreciably modify the pressing force necessary to operate the control button 16.
- FIG. 6 illustrates the mounted lever, after fitting the plug 342.
- the driven tongue extends beyond the lever axis L over a distance greater than a radius from the intermediate cavity.
- the posterior end of the lever must be offset when the insertion opening 341 is crossed by the driven tongue, as illustrated in FIG. 4.
- the front end 128 of the lever is positioned exactly.
- the body 10 is maintained in a mounting position, sufficiently inclined so that the top of the cone serving as the front bearing 348 is a low point for the cone.
- the fins are short enough not to rub on the walls of the intermediate cavity 34, during the tilting of the cocking lever 1 2 along B (see Figure 6). Thus they do not ensure perfect centering of the lever but only its pre-centering (see Figure 5). Furthermore, the fins 1 24 should not hinder the offset of the rear end when crossing the introduction orifice. For this, as illustrated in FIG. 4, the fins form a dihedral whose apex is opposite to the direction of extension of the driven tongue 123, that is to say that the driven tongue is included inside the dihedral.
- the body of a valve according to the invention is not necessarily delivered into a profile.
- a tap comprising several outlets each supplying a crown of a burner with multiple crowns, it may be preferable to produce it by molding. You can use this tap on the front of an oven.
- the control direction is substantially horizontal and the thrust direction may be perpendicular but not necessarily vertical.
- This type of tap can also be adapted to fuels other than domestic gas, for example fuel oil.
- the lever can also have a different shape, for example the leading and / or driven tongues can be replaced by, or included in, respectively other driving means and / or other driven means.
- leading means can be a cylinder instead of a tongue.
- the lever can also be manufactured by other techniques, for example molding or assembly. It can be made of plastic material.
