The structure characteristics of the floating ball pneumatic valve

pneumatic seat sealing structure, unique pneumatic ball valve manufacturing experience for many years with the domestic and foreign advanced technology combined with the design of double pneumatic sealing seat, reliably guarantee the pneumatic valve seal. Professional pneumatic seat processing, pneumatic seat low friction coefficient, pneumatic valve operating torque is small. , can show the state of the pneumatic valve switch handle pneumatic valve stem head adopts the flat structure, and handle the connection is not misplaced, thus ensuring to handle traffic hole in the same direction with the sphere. Electric brake electric pneumatic valve regulating pneumatic valve pneumatic pneumatic valve, when the handle is parallel with pneumatic valve pipe pneumatic valve is in open position; When the handle is with pneumatic valve piping vertical, pneumatic valve in the closed state. , locking device to prevent the pneumatic valve switch by misoperation and unpredictable lines should not have the switch action, as a result of the vibration in the pneumatic valve fully open and close position has a locking hole, available padlock locking pneumatic valves. Especially the pneumatic valve installed in the field or in combustible medium of petroleum and chemicals production line, the locking device can reflect its unique superiority. , pneumatic valve rod structure when the pneumatic valve chamber pressure rises, the pressure of the pneumatic valve body lumen may pneumatic valve stem. To prevent this happening, at the bottom of the pneumatic valve stem has a shoulder, loading pneumatic valve stem from inside the pneumatic valve body, preventing pneumatic valve stem. In this way, to change the packing is more convenient and safe. After can be in the fire at the same time, medium pressure will make the pneumatic valve stem seal face close contact on the flange and pneumatic valve body to prevent medium large leaked from the damaged packing area, have the effect of instantaneous sealing. , antistatic design when operating pneumatic valve, due to the friction between ball and pneumatic seat, will generate static electricity and accumulation in the sphere. In order to prevent electrostatic spark producing, on antistatic device, pneumatic valve will generate static export switching process. The design used in pneumatic valves in low burning gasoline, natural gas, propane, etc will be able to effectively prevent the happening of the accident. , the flange ( Pneumatic valve body and the left body connection) Structure without leakage of pneumatic valve and the connection of the left body is cushion for leaning on of seal, in order to prevent the fire, high temperature or vibration factors such as the severe leak, special design for the pneumatic valve body and the left body metal - Metal contact, form check flange, ensure no leakage. When accidental fire, fire prevention structure, pneumatic seat, packing etc. Nonmetal material will be burn out, and a large number of leakage of the medium can promote more fire. Pneumatic valve of fire prevention structure can prevent leakage of medium a lot. After the fire, the leakage of parts ( The ball with the pneumatic valve, pneumatic valve stem and valve body, the flange) Designed to metal contact, meet the requirements of fire prevention. As shown in figure, once the pneumatic valve seat is burning, sphere under the effect of pressure will directly and pneumatic valve on the metal surface contact, thereby preventing a lot from the burning of pneumatic valve seat leakage of medium.
