Abstract

The invention provides a valve gear which can restrain reduction of slide property of a main valve generated by dimensional change caused by using fluid and can properly control inflow and outflow of the fluid. The valve gear through a drive valve, a third flow path is converted to a state that the fluid can inflow and outflow and a state that the fluid cannot inflow and outflow. Thus, equilibrium of forces of the main valve is changed so that the main valve is abutted against a valve seat component or the main valve separately slide in a valve barrel from the valve seat component, and inflow and outflow of the fluid between a first flow path and a second flow path are controlled. Since a sliding surfacing of the main valve is made of a metal material, dimensional changes can be retrained caused by swelling, shrink, etc. generated by being exposed in the used fluid, thereby restraining reduction of slide property of the main valve. In addition, a part where the main valve and the valve seat component abut is made of a resin material or a rubber material, so that tightness of the main valve and part where the main valve and the valve seat component abut is improved.

Control valve unit
Technical field
The present invention relates to a kind of control valve unit of controlling the inflow and outflow of fluid by the slip of main valve.
Background technique
For example, in the fuel pot of the liquefied gas as fuel of storing liquefied petroleum gas (LPG) (below, be called LPG) or dimethyl ether (below, be called DME) etc., be equipped with the anti-locking apparatus of overfill or fuel supplying device etc.
As being applicable to above-mentioned overfill device or the control valve unit of fuel supplying device, for example, shown in patent documentation 1, proposed by the action of control solenoid valve, balance from the glide direction double side acting of main valve in main valve is changed and main valve is slided, can be transformed into the fuel in the fuel pot state that can towards fuel pot outside, supply with and the state that can not outside fuel pot, supply with thereupon.
Patent documentation 1:WO2010/146968 communique
The control valve unit of the anti-locking apparatus of above-mentioned overfill or fuel supplying device etc. is because carry out required action by the slip of main valve, so main valve must slide smoothly along with actuating valve (Japanese: make the Move man's cap used in ancient times) or the action of solenoid valve.Therefore, for the reactivity of the action that makes relative actuating valve or solenoid valve well and can slide smoothly, and adopt the resinous material of light weight at main valve.But main valve is because being exposed in the fluid, so in the situation of resin main valve, the size change of swelling or contraction etc. can occur because of employed fluid, and might cause the sliding of main valve to descend.For example, in the fuel pot that is being provided with the anti-locking apparatus of the overfill that has disposed the resin main valve or fuel supplying device, store in the situation of above-mentioned DME fuel, be exposed to the easy swelling of main valve in this DME fuel and dimensional changes occurs, the decline of above-mentioned sliding occurs.Thereupon, as the function reduction of control valve unit of the inflow and outflow of control fluid.
Summary of the invention
The invention provides a kind of control valve unit, it can descend to the sliding of following the main valve that the dimensional changes that produces because of the fluid that uses occurs and be suppressed, and can suitably bring into play the function of the inflow and outflow of control fluid.
Control valve unit of the present invention is provided with valve barrel, main valve, load maintainer, the first stream, the second stream, valve base part, the 3rd stream and the actuating valve of tubular, and the valve barrel of above-mentioned tubular has the zone, inner space; Above-mentioned main valve is tabular, be provided in the zone, inner space of above-mentioned valve barrel and this inner space region separation is become the first area of space and second space zone in slidable mode, this main valve is provided with the throttle orifice with this first area of space and second space regional connectivity; Above-mentioned load maintainer loads this main valve towards the second space zone from above-mentioned the first area of space along the glide direction of above-mentioned main valve; Above-mentioned the first stream link to each other with the second space zone facing to the opening portion of the second space area side of above-mentioned throttle orifice and with this second space regional connectivity; Above-mentioned the second stream link to each other with above-mentioned second space zone and with this second space regional connectivity; Above-mentioned valve base part is configured to, thereby by with the above-mentioned main valve butt that slides towards above-mentioned second space area side main valve can further not slided from this butt position towards the second space area side, above-mentioned valve base part is configured to, and makes fluid can not make in inflow and outflow between above-mentioned the first stream and the second stream, under this main valve and state that valve base part separates the fluid can inflow and outflow between the first stream and the second stream under the state of above-mentioned main valve and this valve base part butt; Above-mentioned the 3rd stream links to each other with above-mentioned the first area of space and is communicated with this first area of space; Above-mentioned actuating valve above-mentioned the 3rd stream be transformed into can the inflow and outflow fluid state and state that can not the inflow and outflow fluid, it is characterized in that, above-mentioned main valve formed by metallic material with interior sidewall surface above-mentioned valve barrel slip surface in opposite directions, and the position of above-mentioned main valve and above-mentioned valve base part butt is formed by resin material or rubber material.
In the control valve unit of this structure, by the equilibrium of forces to the main valve effect such as the hydrodynamic pressure that changes the first area of space and second space zone, the loading force that load maintainer applies, thereby main valve is slided in valve barrel, and the inflow and outflow of convection cell between the first stream and the second stream controlled.That is, when by actuating valve the 3rd stream being transformed into the state that fluid can inflow and outflow, the pressure of the fluid that produces in the first area of space is open towards the outside of valve barrel by the 3rd stream.Under this state, when the loading force that the power of main valve effect applied greater than load maintainer by the interior pressure of the interior pressure of the first stream and the second stream, main valve makes fluid can pass through the inflow and outflow between the first stream and the second stream of second space zone towards the first area of space Slideslip.On the other hand, when by actuating valve the 3rd stream being transformed into the state that fluid can not inflow and outflow, the throttle orifice by main valve make the interior pressure of the first area of space and second space zone first-class trackside interior pressure about equally.Under this state, when the interior pressure of first-class trackside is higher than the interior pressure of second trackside in second space zone, must become large from the first area of space side towards the second space area side to the power of main valve effect, so, main valve not towards the first area of space Slideslip and with the valve base part butt, fluid can not be flowed out from low the second stream of the high first-class road direction pressure of pressure.In addition, by actuating valve the 3rd stream is transformed into fluid can not the state of inflow and outflow under, when the interior pressure of second trackside is higher than the interior pressure of first-class trackside in second space zone, as long as the interior pressure of the interior pressure of the first stream and the second stream is to the power of the main valve effect loading force greater than load maintainer, main valve can flow out from the first low stream of the high second road direction pressure of pressure fluid just to the first area of space Slideslip.
And, in this control valve unit, main valve is with being difficult to form slip surface because of the metallic material that produces swelling, contraction etc. with fluid, so, with adopting the resin material that produces easily swelling, contraction etc., the situation that rubber material forms slip surface to compare, can dimensional changes that follow this slip surface generation swelling, contraction etc. to cause be suppressed.The sliding that thus, can suppress main valve reduces, suitably brings into play the function that the inflow and outflow of above-mentioned convection cell is controlled.In addition, because the position of main valve and valve base part butt is made of resin material or rubber material, so, compared by the situation that metallic material consists of with this butt position, can improve the sealing at the position of main valve and valve base part butt.And then main valve of the present invention is compared with the situation that only is made of metallic material can lightweight, so, for the pressure that produces at the first area of space by the driving of actuating valve change reactive good, can slide more swimmingly.Therefore, can further suitably bring into play the function of the control valve unit of controlling as the inflow and outflow of convection cell.
Also proposed in the control valve unit of the invention described above, main valve is formed the scheme that is the コ glyph shape facing to the cross section of the first area of space opening.
The control valve unit は that so consists of just can not strengthen the volume of the first area of space owing to do not strengthen the boundary dimension of main valve, so can make the speed of the pressure variation in the first area of space that the driving because of actuating valve produces slack-off.At this, in the time can becoming at the state transformation of the 3rd stream inflow and outflow the state that fluid can not be in the 3rd stream inflow and outflow by actuating valve from fluid, if main valve sharp towards the second space area side slide and with valve base part butt, the then water hammer that sharply rises of the more fast pressure that more can occur because of the inertia of this fluid in the first stream of the flow velocity of the fluid from the first stream towards the second flow path.But, according to the control valve unit of this formation, owing to can make the speed of the pressure rise in the first area of space slack-off, so, can suppress the rapid slip of main valve and the degree of water hammer is suppressed.
Also proposed such scheme, that is, in the control valve unit of the invention described above, control valve unit is provided in fuel pot, and the first stream is configured to be communicated with outward with fuel pot; The second stream and the 3rd stream be configured to fuel pot in be communicated with; Actuating valve is used for lower the 3rd stream of situation of the fuel shortage established amount in being stored in fuel pot and is transformed into state that fluid can inflow and outflow, the fuel in being stored in fuel pot and is transformed into the state that fluid can not inflow and outflow more than or equal to lower the 3rd stream of the situation of established amount.
The control valve unit of this formation, can be from the first stream by the second stream filling fuel in the fuel pot when the fuel shortage established amount in the fuel pot, when fuel reaches established amount, make fuel not flow to the second stream, stop the filling of fuel forcibly from the first stream.That is, can be the control valve unit of this formation as the anti-locking apparatus of overfill, the anti-locking apparatus of this overfill is used for preventing the overfill towards the fuel of fuel pot filling.
Also proposed such scheme, that is, in the control valve unit of the invention described above, control valve unit is provided in fuel pot; The first stream be configured to fuel pot in be communicated with; The second stream is configured to be communicated with the petrolift of motor; The 3rd stream is configured to be communicated with the second stream; Actuating valve is constituted as solenoid valve.
The control valve unit of this formation by driving control as the actuating valve of solenoid valve, can become the Fuel switching of supplying with towards the petrolift of motor supply and supply to stop.
Control valve unit of the present invention, as mentioned above, by actuating valve the 3rd stream is transformed into state that fluid can inflow and outflow and state that can not inflow and outflow, thereby, make from the first area of space side and change to the power of main valve effect and from the equilibrium of forces of second space area side to the main valve effect, thereby this main valve is slided in valve barrel main valve is separated with the valve base part butt or from valve base part, the inflow and outflow of convection cell between the first stream and the second stream controlled, main valve, because its slip surface is formed by metallic material, so can suppress because exposing to the open air in the swelling of following of using fluid in the slip surface generation, the dimensional changes of contraction etc., suppress the reduction of the sliding of main valve.In addition, main valve, owing to formed by resin material or rubber material with the position of valve base part butt, so, compared by the situation that metallic material consists of with this abutting part material, can improve the sealing at position of the butt of main valve and valve base part.And, by such effect, can more suitably bring into play the function that the inflow and outflow of above-mentioned convection cell is controlled.

Embodiment
(embodiment 1)
Embodiment 1 control valve unit 1, embodiment 1 control valve unit 1, as shown in Figure 1, tabular main valve 3 can be configured in the zone, inner space of valve barrel 2 cylindraceous slidably, by this main valve 3 zone, above-mentioned inner space is divided into the first area of space 4 and second space zone 5.In addition, on valve barrel 2, linked respectively with the first stream 6 of second space zone 5 tubuloses that are communicated with, with the 3rd stream 8 of the second stream 7 of regional 5 tubuloses that are communicated with of second space and the tubulose that is communicated with the first area of space 4.In addition, be provided with and valve base part 9 towards main valve 3 butts of these second space zone 5 Slideslips in the second space of valve barrel 2 zone 5 sides.By making main valve 3 and these valve base part 9 butts, make this main valve 3 can not be from this butt position further towards second space zone 5 Slideslips, and, can cut off the first stream 6 and the second stream 7 and the inflow and outflow of limit fluid between these streams.Moreover, being equipped with actuating valve 13 at control valve unit 1, this actuating valve is used for 8 conversion of the 3rd stream are driven into open state that fluid can inflow and outflow and blocking that can not inflow and outflow.
Above-mentioned main valve 3 is formed by cylinder section cylindraceous 16 and is arranged on the shape that cross section that the discoideus bottom 17 of the one-sided end of this cylinder section 16 consists of is the コ font, and cylinder section 16 is formed by metallic material, and bottom 17 is formed by resin material.That is, main valve 3 and interior sidewall surface 2a To valve barrel 2 slip surface 16a are in opposite directions formed, are formed by resin material with the position of valve base part 9 butts by metallic material.And the main valve 3 that the cross section is the コ glyph shape is configured in the zone, inner space of valve barrel 2 in the mode facing to the first area of space 4 side openings.In addition, main valve 3 is loaded towards valve base part 9 sides by the elastomeric spring 10 that is provided in the first area of space 4.And then, be formed with the first area of space 4 and second space zone 5 throttle orifices that are communicated with 11 at main valve 3.This throttle orifice 11 is formed, and under the state of main valve 3 and valve base part 9 butts the first area of space 4 is communicated with the first stream 6 sides.
The control valve unit 1 of such present embodiment 1, the first area of space 4 and second space zone 5(the first stream 6 and the second stream 7) hydrodynamic pressure, the such equilibrium of forces that is applied on main valve 3 of loading force of elastomeric spring 10 generations change, thereby make main valve 3 in valve barrel 2 interior slips, convection cell is controlled in the inflow and outflow of 7 of the first stream 6 and the second streams.Fig. 2 represents to act on the appearance of the power on the main valve 3.In Fig. 2, the arrow of solid line represents flowing of fluid, and hollow arrow represents to act on the power on the main valve 3.As shown in Figure 2, the power up that is produced by the hydrodynamic pressure of the first stream 6 in main valve 3 effect, the power up that is produced by the hydrodynamic pressure of the second stream 7, the power down that is produced by the hydrodynamic pressure of the first area of space 4, the power down that is produced by elastomeric spring 10.
Below, the action that the inflow and outflow of 1 pair of fluid from the first stream 6 sides towards the second stream 7 side flow of control valve unit is controlled is described.
Fig. 3 represents actuating valve 13 is driven valve, the state that fluid is flowed towards the second stream 7 from the first stream 6.Under this state, the first area of space 4 is opened by the 3rd stream 8, so, compare with the hydrodynamic pressure of the first area of space 4 and the downward power of 10 pairs of main valves of elastomeric spring, 3 effects, by the hydrodynamic pressure of the first stream 6 and the hydrodynamic pressure of the second stream 7 power that makes progress that main valve 3 acts on is become greatly.Thus, main valve 3 is towards the first area of space 4 Slideslips, and fluid flows towards the second stream 7 by second space zone 5 from the first stream 6.
Then, in Fig. 4, be illustrated in the state that actuating valve 13 is closed behind the valve that so makes under the state that fluid flows from the first stream 6 towards the second stream 7.Under this state, because actuating valve 13 closes valve, the fluid that flows into the first area of space 4 by the throttle orifice 11 via main valve 3 rises the hydrodynamic pressure of the first area of space 4, and the hydrodynamic pressure of the hydrodynamic pressure of this first area of space 4 and the first stream 6 becomes about equally.In addition, owing to be lower than the hydrodynamic pressure of the first stream 6 as the hydrodynamic pressure of second stream 7 in the downstream side of fluid, so, by the downward power of fluid pressure action on main valve 3 of the first area of space 4, greater than the power that makes progress of fluid pressure action on main valve 3 by the first stream 6 and the second stream 7.Thus, main valve 3 is because the power of effect becomes large and down sliding downwards.
So during main valve 3 down sliding, main valve 3 and valve base part 9 butts can not flow out from the first stream 6 fluid towards the second stream 7.Like this, actuating valve 13 closes valve and makes state representation that fluid can not flow out from the first stream 6 towards the second stream 7 among Fig. 5.Under this state, even the change in fluid pressure of the first stream 6, the hydrodynamic pressure of the hydrodynamic pressure of the first area of space 4 and the first stream 6 also about equally.Therefore, as long as the hydrodynamic pressure of the second stream 7 is lower than the hydrodynamic pressure of the first stream 6, the loading force of the hydrodynamic pressure of the first area of space 4 and elastomeric spring 10 is to the downward power of main valve 3 effect, the power that makes progress that just always greater than the hydrodynamic pressure of the first stream 6 and the second stream 7 main valve 3 is acted on.Thus, main valve 3 is kept the state with valve base part 9 butts, so fluid can not flow out towards the second stream 7 from the first stream 6.
Like this, according to the control valve unit 1 of present embodiment 1, by actuating valve 13 being opened and closed the equilibrium of forces that changes the main valve effect, main valve 3 is slided, thus can be to suitably controlling towards the inflow and outflow of the mobile fluid of the second stream 7 from the first stream 6.
At this, when actuating valve 13 closes valve, if main valve 3 sharp towards second space zone 5 Slideslips and with valve base part 9 butts, the flow velocity of the fluid that then flows from the first stream 6 towards the second stream 7 is faster, and more meeting produces the rapid water hammer that rises of the pressure that makes in the first stream 6 under the effect of the inertia of this fluid.But, control valve unit 1 according to present embodiment 1, the main valve 3 that is the コ glyph shape by the cross section has strengthened the volume of the first area of space 4, so, the speed that the pressure in this first area of space 4 that can slow down change, the downward power that acts on the main valve 3 is relatively slowly become greatly.Thus, can suppress the rapid slip of main valve 3 and suppress the degree of water hammer.
In such control valve unit 1, main valve 3 exposes to the open air in fluid, but the cylinder section 16 that consists of slip surface 16a is formed by metallic material, so, can suppress the dimensional changes because of swelling that fluid causes, contraction etc.Thus, can suppress the reduction of the sliding of main valve 3.In addition, because the bottom 17 of main valve 3 and valve base part 9 butts is made of resin material, so, compared by the situation that metallic material consists of with this bottom 17, can improve the sealing of valve base part 9 and bottom 17.As mentioned above, the control valve unit 1 of present embodiment 1 can suitably be brought into play the function that the inflow and outflow of above-mentioned convection cell is controlled.
And then main valve 3 is compared with the situation that is only formed by metallic material can lightweight.In addition, because forming the cross section, main valve 3 is the shape of コ font thereby also can lightweight.By making in this wise main valve 3 lightweights, can make main valve 3 have good reactivity with respect to the driving because of actuating valve 13 in the pressure variation that the first area of space 4 produces, can slide more swimmingly.Therefore, the control valve unit 1 of present embodiment 1 can suitably be brought into play the function that the inflow and outflow of above-mentioned convection cell is controlled.
