The concept of gas pipeline pneumatic valve and requirements

pneumatic valves are used for opening and closing pipe channel or adjust the equipment of pipeline medium flow. So the pneumatic valve body high mechanical strength, flexible rotating components, sealing components for durability and KangFuXing of medium to strong, and good parts commonality, before installation should be done air tightness test, no leakage of qualified, reject shall not be installed. General pneumatic valve pneumatic valve body on the sign, the medium flow arrow direction, must pay special attention to, may not be installed backwards.
installation location from the long-term operation and maintenance, as far as possible, convenient operation and maintenance, as well as considering the assembly good appearance, pneumatic valve handwheel shall not down, avoid lift up his countenance; Pneumatic valve handwheel landing up, shall not be skewed; On the premise of process allows, pneumatic valve handwheel should be located in the chest high, so that the rev pneumatic valve; Pneumatic valve stem gate do not install in the ground, to prevent corrosion.
