Based on above-mentioned principle, implementation of the present invention is as follows:
Referring to Fig. 2 a and Fig. 2 b, linkage mechanism 1 mainly comprises bearing 11, straight pin 12, driving-rod 13, roller 14.Wherein bearing 11 is provided with four screw via holes, can be fixed on the end face of main valve body 6 outlet sides by four socket head screws 15.Driving-rod 13 two ends are respectively equipped with pin hole, and the one end is arranged on bearing 11 by straight pin 12 is rotating, so that driving-rod 13 can rotate around straight pin 12, the other end of driving-rod 13 is connected with roller 14 by another straight pin simultaneously.
Be connected with main valve body 6 and can conveniently have four direction to select arbitrarily according to as installed for linkage mechanism 1.
Referring to Fig. 3, touch head mechanism 2 is positioned at the outlet side of main valve body, and it comprises: locknut 21, piston 22, an O RunddichtringO 24 and the 2nd O RunddichtringO 23.
Wherein locknut 21 is settled on the outlet side of main valve body, and enters in the air cavity of main valve body.To provide a passage on this locknut 21, be provided with an O RunddichtringO 24 between sealing effect locknut 21 and the main valve body in order reaching, and this O RunddichtringO 24 to be positioned at the Gewindefreistiche place of locknut 21.
Piston 22 is placed in locknut 21 upper channels, and between is provided with the 2nd O RunddichtringO 23, to reach sealing effect.One end of piston 22 stretches out outside the main valve body by locknut 21, and is corresponding with the driving-rod 13 in the linkage mechanism 1, depresses at the lower of driving-rod 13, can driven plunger 22 in locknut 21 interior motions.The other end of piston 22 stretches in the inner chamber of main valve body, is used for driving nozzle mechanism 3.
Nozzle mechanism 3 mainly comprises nozzle 31 and Returnning spring 33, and its integral body is placed in the air cavity of main valve body.Nozzle 31 is settled in the air cavity of main valve bodies, matches with piston 22 in the touch head mechanism 2, is driven by it.Under the driving of piston 22, can move along air cavity, realize the conducting of suction port and air outlet.Be arranged with Returnning spring 33 on the nozzle 31,33 pairs of nozzles 31 of Returnning spring provide reseting elasticity, so that nozzle 33 masterpiece time spent returning position outside.
For improving sealing, between the air cavity inwall of nozzle 31 and main valve body, be provided with the 3rd O RunddichtringO 32.
Referring to Fig. 4, the valve base mechanism 4 among the present invention matches with emergency opening mechanism 5, is arranged on the inlet end of main valve body.Wherein valve base mechanism 4 is positioned at the main valve body air cavity near valve suction port place, it comprises valve block 41, screw 42, bearing nut 43 and bearing handle 44, its middle valve plate 41 is fixed on the top of bearing handle 44 by screw 42 and bearing nut 43, this valve block 41 matches with nozzle 31 in the nozzle mechanism 3, can be with sealed-in nozzles 31 when both close contacts, thus realize closing between main valve body suction port and the air outlet.Bearing handle 44 is placed in the emergency opening mechanism 5, and so that the valve block 41 on it be in the stroke that nozzle 31 moves along air cavity, in order to can realize the conducting between main valve body suction port and the air outlet and close.
Wherein, emergency opening mechanism 5 is arranged on the inlet end of main valve body 6, and it comprises nut 51, Returnning spring 52, draw ring 54, position-limitting pin 55.
Be the installation position of restriction bearing handle 44, the bottom of stretching out outside the main valve body at bearing handle 44 is provided with position-limitting pin 55, limits the position of whole valve base mechanism 4 with this.
Simultaneously, between nut 51 and bearing handle 44, be provided with Returnning spring 52, provide reseting elasticity with this by 52 pairs of bearing handles 44 of Returnning spring, so that bearing handle 44 is returning position at External Force Acting.
In order to reach excellent effect, be provided with resettlement groove 57 at nut 51 and bearing handle 44 relative end faces, an end of Returnning spring 52 is placed in this resettlement groove 57, and an end contacts with the top of bearing handle 44.
For the ease of the operation to bearing handle 44, pass the bottom that nut 51 stretches out outside the main valve body at bearing handle 44 and be provided with a draw ring 54.
In order to reach sealing effect, bearing handle 44 is placed in the nut 51 by the 4th O RunddichtringO 53, is provided with the 5th O RunddichtringO 56 between nut 51 and the main valve body 6 simultaneously.
Based on the present invention that such scheme forms, its implementation is as follows:
Under normal state: externally in the mechanical moving element collision touch head mechanism during roller, driving-rod connects 13 under external force, rotates (shown in Fig. 2 a) around straight pin 12, and driven plunger 22, and it is moved downward.Piston 22 will further promote nozzle 31, its elastic force that overcomes Returnning spring 33 is moved down, valve block 41 close contacts when nozzle 31 is pressed onto certain position and on the bearing handle 44, and with nozzle 31 sealings, this moment, nozzle 31 was in the closed position, thereby so that whole switch valve is in closed condition.
When the exterior mechanical parts leave roller in the touch head mechanism, nozzle 31 will lose external pressure, Returnning spring 33 will produce reseting elasticity to nozzle 31, under the effect of this power, nozzle 31 is back mobile, with piston 22 pushed home, and break away from and return to the enable possition with valve block 41 on the bearing handle 44, thereby so that whole switch valve is in opening state.
In case of emergency: pull out position-limitting pin 55, so that bearing handle 44 is in movable state, this moment is by pulling draw ring 54, so that overcoming the reseting elasticity of Returnning spring 52, bearing handle 44 moves down, so that the valve block 41 on the bearing handle 44 breaks away from nozzle 31, so that nozzle 31 is in opening state, thereby by force switch valve is opened.
When need not emergency opening, unclamp draw ring 54, so that bearing handle 44 returns to the origin-location under the reseting elasticity effect that Returnning spring 52 produces, and carries out the position restriction by position-limitting pin 55, just can normally use.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
