The utility model provides a kind of operated pneumatic valve, a kind of operated pneumatic valve, it is characterised in that including valve body, bonnet, air chamber
Through hole, air inlet/outlet are provided with housing, the bonnet, the gas chamber shell is arranged on valve inner, passes through fixed plate and valve
Body is connected, and is provided with passage in the fixed plate, the bonnet is connected by bolt with valve body, while the bonnet and air chamber
One sealed air chamber of housing formation, air inlet/outlet one end connection control source of the gas, other end connection sealed air chamber, the sealing
Piston, piston rod, spring are provided with air chamber, the spring is socketed on piston rod, piston rod one end connection is arranged on close
The piston sealed in air chamber, the other end passes sealed air chamber's connection sealing device, and the valve body is provided with air inlet, the sealing dress
It is set on the cone structure with air inlet fitted seal, the gas chamber shell to be provided with and coordinates the first groove, described the with bonnet
The second sealing ring for being provided with and being engaged with piston rod on the first sealing ring, the gas chamber shell is provided with one groove, it is described
The 3rd sealing ring being engaged with sealing device is provided with air inlet.
Further, the bonnet is provided with 3 through holes.
Further, the piston rod is connected with sealing device by screw device.
The beneficial effects of the utility model：
The utility model constitutes sealed air chamber due to being provided with gas chamber shell on bonnet, while air chamber is arranged on valve body
It is internal so that valve body structure is compacter, the utility model due to being provided with piston, piston rod and spring in air chamber, when
There is control air pressure when come in, promote piston advances forward, the final sealing device motion for driving piston rod top so that valve
Door inlet and outlet conducting, so as to realize the unlatching of valve, when cutting-off controlling source of the gas, under spring self-acting, piston rod to
After move, band dynamic sealing device is moved to the left, so as to realize sealing, and such valve inlet and outlet are just cut-off, so as to realize
The closing of valve, the utility model is provided with the air-tightness that three sealing rings ensure that valve, and fixes gas using fixed plate
Room housing, then rationally coordinate with bonnet, neither influence is used, and again safeguarding installation becomes more convenient, and piston rod is filled with sealing
Put using threaded connection, be also convenient for the maintenance with late gate.
