Serous pneumatic valve application advantages and working principle

serous pneumatic valve is widely used in petroleum, chemical, thermal power plants such as oil, water, steam piping connected or truncate the medium inside the pipe opening and closing device.
opening and closing by rotating the handwheel action is complete, the pneumatic valve is mainly by the left and right pneumatic valve body, U ring, disc, steel nut, pneumatic valve stem, stents, hand wheel, etc.
chronological rotates, pneumatic valve closed; Whereas for the pneumatic valve open.
serous pneumatic valve is to absorb and digest advanced pneumatic valve technology at home and abroad on the basis of the pneumatic valve body structure, sealing, drive and electrical control aspects has made the further updates.
the product of simple structure, small volume, light weight, small flow resistance, medium is not easy to precipitate in pneumatic valve body, and the device is convenient, and many other advantages, have a combination of manual and electric hydraulic operating functions.
brake of the pneumatic valve opening and closing is ram, ram movement direction and perpendicular to the direction of flow of slurry pneumatic valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used model of pneumatic valve gate sealing surface form a wedge, the wedge Angle vary with parameters of pneumatic valve, usually, when the medium temperature is not high as ° '. Wedge serous pneumatic valve disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.
brake pneumatic valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the pneumatic valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most brake is forced sealing pneumatic valve, pneumatic valve closing, namely to rely on outside force forced the ram pressure to the pneumatic valve seat, to ensure the sealing surface sealing.
