Two valve plates are fixed on gas piping, are provided with bellows on gas piping, and bellows can be with convergent-divergent.When the first valve plate with
When second valve plate separates, bellows shrinks, and so could adjust the distance between the first valve plate and the second valve plate, can make second
Valve plate is smoothly moved, and is realized the break-make to gas piping, when the second valve plate completes the break-make to gas piping, is moved back to gas pipe
When between road, bellows axial expansion, by clamping device, clamps the first valve plate and the second valve plate, gas piping is carried out
Effectively seal.As bellows needs to shrink repeatedly and expands, which is washed away in order to protect bellows to reduce coal gas as far as possible,
Extend its service life, ripple inside pipe wall is provided with neck bush bellows is protected.Meanwhile, bellows can be dismantled down
Come, when bellows occur damage when, can a dismounting bellows which is repaired, it is not necessary to whole plate valve gear is torn open
Remove, so time-consuming, use manpower and material resources sparingly, extend the service life of whole push-pull valve.In sum, the utility model is carried
For coal gas push-pull valve investment cost few, installation and repairing is convenient, safe and reliable, switchs convenient and swift.
