Briefly describes the structure characteristics of pneumatic valve forged steel gate

structure features: there are three kinds of pneumatic valve body cover forged steel gate connection design form. The first is a body cap bolt connection pneumatic valves, forged steel gate design of the pneumatic valve in this connection, the pneumatic valve body and bonnet bolting, spiral wound gasket seal, the advantage is convenient for maintenance. The second body cover welding connection pneumatic valves, forged steel gate design of the pneumatic valve in this connection, the pneumatic valve body and valve cover all welding seal, advantage is no external leakage. Pressure self-tightening type pneumatic valve cover, for a third pneumatic valves, forged steel gate design of the pneumatic valve in this connection, the pneumatic valve connected to the pneumatic valve cover with screw mosquitoes, since internal pressure sealing ring seal, advantage is that the higher the internal pressure, the greater the sealing performance is better. Fluid resistance small, sealing surface Chong brush and erosion by the medium. Open and close more effort. Medium flow direction is not restricted, disturbed flow, reduce the pressure. Shorter form, simple structure, good manufacturing technology, wide application scope.
