Description

The chlorine cylinder attachment valve

The utility model relates to a kind of chlorine cylinder attachment valve.

The chlorine cylinder that generally uses exports conveyance conduit to through behind the reduction valve now, when finishing using, when changing chlorine cylinder, conveyance conduit also has the chlorine of abundant residues to flow backwards from pipeline, serious environment pollution and infringement user's health, valve adopts with chlorine cylinder and is threaded simultaneously, and frequent dismounting causes thread abrasion easily, sometimes even needle-valve is twisted into two parts, and make chlorine leakage.

The purpose of this utility model is to provide a kind of chlorine cylinder attachment valve, and it is fast simple that it can make chlorine cylinder be connected with the installation of reduction valve, reduces the wearing and tearing between the parts, and can prevent the leakage of chlorine.

In order to achieve the above object, the technical solution adopted in the utility model is: described chlorine cylinder attachment valve is made up of joint and connecting sleeve, the cavity that one two opening is arranged in the joint, one termination chlorine cylinder of cavity opening, one termination connecting sleeve, one vent plug that is pressed with spring is arranged, spring vent plug is sealed and matched outlet end that cavity is connected with connecting sleeve in the cavity; The cavity that one both ends open is also arranged in the connecting sleeve, cavity one termination reduction valve, an other port pass joint, the cavity port that has a vent plug sealing that is pressed with spring to communicate in the cavity with joint, the left end of vent plug has the piston air-inlet pole of a hollow, and its two end part have vent makes the cavity in the piston air-inlet pole communicate with the external world, and the piston air-inlet pole right-hand member is inserted in the connecting sleeve movingly, left end protrudes connecting sleeve, and the connecting sleeve left part also has one can be automatically locked and trip gear with joint.

Adopt chlorine cylinder attachment valve described in the utility model, one end and the chlorine cylinder of joint are connected and fixed, one end and the reduction valve of connecting sleeve are fixed, connecting sleeve entangles joint, between them be automatically locked and trip gear is automatically locked, joint and connecting sleeve are connected together, simultaneously vent plug in the piston air-inlet pole jack-up joint in the connecting sleeve and the vent plug in the connecting sleeve, joint is connected by the cavity in the piston air-inlet pole, thereby realizes ventilation; When not needing to ventilate, stir being automatically locked and trip gear of piston/cylinder left part, connecting sleeve is separated with joint, vent plug in the joint and the vent plug in the connecting sleeve lose compressing of external force and the original place of rebounding, again closed joint and connecting sleeve, thus ventilation stopped.Chlorine cylinder attachment valve described in the utility model is simple to operate, safety can prevent the leakage of chlorine effectively, and with when connecting sleeve separates, the vent plug of connecting sleeve keeps closed state at joint for it, can prevent that reduction valve from connecing ducted residual chlorine gas leakage in succession and damaging user's health.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 chlorine cylinder attachment valve described in the utility model.

Embodiment:

As shown in Figure 1, joint a comprises seal ring 1, nut connecting base 2, spring 3, sealing slide block 4, seal ring 5, connects valve core 6, seal ring 23.One interface that is connected with chlorine cylinder 27 is arranged on the nut connecting base 2, have cavity 26 in the nut connecting base, connecting valve core 6 one ends is placed in the cavity 26, its other end is connected with connecting sleeve, one sealing slide block 4 is arranged in the cavity 26, sealing slide block 4 one ends are pressed with spring 3, and an other end compresses the outlet of cavity 26 under the elastic force effect of spring.

Connecting sleeve b comprises seal ring 12, piston air-inlet pole 13, piston/cylinder 14, seal ring 15, closed ball 16, sealing spring 17, aerating connecting sleeve 18 and is positioned at being automatically locked and the mechanism of throwing off with joint a of connecting sleeve left end.Have cavity 25 in the aerating connecting sleeve 18, cavity 25 1 ends are connected with reduction valve, an other end has a closed ball 16 for being communicated with the air inlet end of joint b in the cavity 25, closed ball 16 1 ends are pressed with sealing spring 17, the air inlet end of an other end enclosed cavity 25.The left end of aerating connecting sleeve 18 is a piston/cylinder 14, be with piston air-inlet pole 13 in the piston/cylinder 14 movingly, piston air-inlet pole 13 hollows, its side faces at both ends have through hole 28 makes the cavity 29 in the piston air-inlet pole 13 communicate with the external world, and piston air-inlet pole 13 left ends protrude outside the piston/cylinder 14.Left end at piston/cylinder 14 has an energy and joint to be automatically locked and the mechanism of throwing off.This mechanism comprises v-depression 24 on the joint a and the thrust spring 7 on the connecting sleeve b, thrust slide block 8, outer casing spring 9, connects overcoat 10, fittings body 11, interior sleeve spring 20, ball 22.Fittings body 11 is a cylinder, is placed in piston/cylinder 14 left ends, has through hole on the wall of fittings body, and ball 22 is embedded in the through hole.The inboard of ball 22 is with thrust slide block 8, and thrust slide block right-hand member is pressed with interior sleeve spring 20; The outside of ball 22 is with and connects overcoat 10, connects overcoat 10 right-hand members and pushes down outer casing spring 9.Left end at ball 22 also has a thrust spring 7 to be embedded in the fittings body outside, to prevent that connecting overcoat 10 ejects.

When external force promotes connecting sleeve b when joint a moves, the connection valve core 6 of joint a compresses thrust slide block 8, interior sleeve spring 20 compressions, when v-depression 24 moves to ball 22 positions, ball 22 ejects from through hole and falls in the v-depression 24, connection overcoat 10 loses compressing of ball 22 and ejects under the promotion of outer casing spring 9, arrive thrust spring 7 positions and stop, the inwall that connect overcoat 10 this moment has sealed ball 22 and has ejected from v-depression 24, joint a be connected overcoat b realization self-locking.Joint be connected overcoat and realize self-locking in, the two ends of piston air-inlet pole 13 enter respectively in the cavity 25 of the cavity 26 that connects valve core 6 and connecting sleeve 18, and back down sealing slide block 4 and closed ball 16, cavity in the piston air-inlet pole 13 makes cavity 25 be communicated with cavity 6, seal ring 21 on the piston air-inlet pole 13 forms hermetic seal with the inwall that is connected valve core 6, thereby realizes ventilation.Connect overcoat 10 when firmly stirring to the right, ball 22 ejects from V-shaped groove, and thrust slide block 8 is got back to original position under the promotion of interior sleeve spring 20, and joint is ejected, and sealing slide block 4 and closure ball 16 lose external force and compress, and bullet meeting original place forms hermetic seal again.
