Description
Technical field
This utility model relates to field of mechanical technique, is specially a kind of gas direction control valve.
Background technology
Gas direction control valve is a kind of in order to change the control element that gas in pipelines flows to.This element is widely used in various pipe-line construction, such as natural gas region conveying, heating installation conveying, the research application of gas experiment room etc..In actual applications, can according to different need directional control valve divide into several classes other, and general gas control valve all can run into owing to gas pressure is excessive, and it is difficult to the problem driven, owing to the pressure of gas directly bears against spool face, cause the frictional force between spool and housing to become big, thus be difficult to drive.
Utility model content
The purpose of this utility model is to provide a kind of gas direction control valve, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model following technical scheme of offer: a kind of gas direction control valve，Including housing、Mobile room、Mobile room air inlet、Piston、Air-pressure chamber、Air-pressure chamber air inlet、Inlet channel、Outlet passageway、Gas transition passages and spool，One end of described housing is provided with mobile room described in，One end of described housing is provided with inlet channel described in，The other end of described mobile room is provided with mobile room air inlet described in，The inside of described mobile room is provided with piston described in，The end face of described piston is provided with spool described in，Described spool is provided with a L-shaped gas transition passages in the one end being positioned at described inlet channel，Described housing is being positioned at position corresponding to described gas transition passages is provided with to organize described outlet passageway more，Described housing is provided with air-pressure chamber described in the bottom being positioned at described spool，One end of described air-pressure chamber is provided with described air-pressure chamber air inlet.
Preferably, described mobile room air inlet connects an adjustable air pump by pipeline.
Preferably, it is provided with a seal washer between side and the inwall of described mobile room of described piston.
Preferably, described air-pressure chamber air inlet connects an adjustable air pump by pipeline.
Preferably, described inlet channel is connected by pipeline provides the air pump of gas.
Preferably, described outlet passageway is connected with the device needing air inlet respectively by pipeline.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, easy to use, when needing the position changing spool, the air-pressure chamber being positioned at spool bottom can provide thrust upwards, thus offsets the air pressure from top, and then is moved easily spool.
