Abstract
The invention relates to a mechanical accessory, in particular to a stop valve for opening and closing an inflammable and explosive gas steel cylinder, which comprises a mechanism which is arranged on a shell and used for communicating or sealing a gas source port and a gas outlet. The stop valve provided by the invention is used, thus safety performance is improved and personal safety of the public is ensured.
Description
Technical field
The present invention relates to a kind of mechanical fitting, especially relate to a kind of stop valve that opens and closes flammable explosive gas medium steel cylinder.
Background technique
At present, the pressurized gas cylinder valve that generally uses of prior art mainly adopts manually operated valve or solenoid valve.Manually operated valve exists opening speed shortcoming slowly, very easily causes security incident and solenoid valve is used to open and close flammable explosive gas medium steel cylinder.
Summary of the invention
Technical problem to be solved by this invention provides a kind of stop valve that opens and closes flammable explosive gas medium steel cylinder that is applicable to that overcomes the prior art defective.The technological scheme that the present invention solves its technical problem employing is: a kind of stop valve, and it comprises shell, shell is provided with the mechanism that is communicated with or seals source of the gas mouth and air outlet.Technical problem to be solved by this invention also can further be solved by following technical solution: the mechanism of connection or sealing source of the gas mouth and air outlet is that shell is provided with source of the gas mouth and air outlet, one end of shell is provided with piston cavity and connects driving casing, driving casing is provided with the driving mouth that is communicated with piston cavity, be provided with piston in the piston cavity, be provided with the post hole in the shell, the post hole is communicated with the air outlet, the other end of shell is provided with cavity and connects gland, cavity is communicated with the source of the gas mouth, be provided with valve in the cavity, the two ends of spring act on respectively on gland and the valve, and the reducing stick harness on the piston stretches into the post hole and the valve of conflicting, the driving casing thimble that is threaded, the top conflict piston of thimble.Piston cavity among the present invention connects driving casing and is connected gland with shell and all can adopts and be threaded.The present invention has improved Safety performance owing to adopt technique scheme, has ensured the public's personal safety.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments of the invention the present invention is described in further detail:
Fig. 1 is structural representation master sectional view of the present invention (being the C-C sectional view of Fig. 2).
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3.Shell of the present invention is provided with source of the gas mouth 9, air outlet 10, one end of shell 8 is provided with piston cavity 11 and connects driving casing 1, be provided with piston 3 in the piston cavity 11, be provided with post hole 12 in the shell 8, post hole 12 is communicated with air outlet 10, the other end of shell 8 is provided with cavity 13 and connects gland 7, cavity 13 is communicated with source of the gas mouth 9, be provided with valve 5 in the cavity 13, the two ends of spring 6 act on respectively on gland 7 and the valve 5, and the reducing stick harness 14 on the piston 3 stretches into post hole 12 and the valve 5 of conflicting, driving casing 1 thimble 15 that is threaded, the top conflict piston 3 of thimble 15, the driving mouth 2 on the driving casing 1 can be communicated with piston cavity 11 through bullport 16.
Embodiment 1: with reference to Fig. 1, Fig. 2, Fig. 3.Fig. 1 for valve at the hold one's breath state of source mouth, air outlet of the effect lower seal of spring.External drive gas pressure source (not providing in the accompanying drawing) is inserted the driving mouth, make driving air pressure enters with driving mouthful through bullport and is communicated with piston cavity and acts on the piston promotion piston moving linearly left in piston cavity, then overcome the active force of spring, make valve break away from the left end in post hole, thereby gap, the air outlet of gas medium between the thin diameter section of source of the gas mouth, cavity, post hole and reducing stick harness flowed out.Cut off driving air pressure, under the effect of spring, can seal source of the gas mouth, air outlet.
Embodiment 2: with reference to Fig. 1, Fig. 2, Fig. 3.Present embodiment is on embodiment 1 basis, and the thimble that has been threaded on driving casing in case take place to drive the situation of air pressure disappearance, turns thimble (on outer-hexagonal nut) and with mobile piston, also can be communicated with or seal source of the gas mouth, air outlet.
