Exhaust pneumatic valve function and principle, 2) — —

when air out, when the water into the line, plug head stops at the bottom of the positioning frame, a large number of exhaust. Water into the ball float pneumatic valve, transmission plug head to shut down, stop the exhaust. Naturally occur a small amount of gas pipeline is in operation, the gas will be gathered in the upper tube, a level, pneumatic valve inside water levels fall, floating ball well down air to escape from holes in the event of a power outage, stop the pump and the pipe flow space-time at any time there will be a negative pressure, floating ball well down, open the hole to drive big hole a large number of air intake to ensure pipeline peace.
to work properly. If not with exhaust pneumatic valve, pipe be gas resistance, exhaust pneumatic valve used for pipe the highest point on the road or bend or there is breath, to exclude tube gas to unclog the pipes. Makes the pipeline water capacity can not meet the design requirements, secondly; Pipeline power failure during operation, stop the pump pipe way timely negative pressure will cause pipeline vibration or broken. Row, inlet pneumatic valve is quickly put the air suction pipe, prevent the pipeline vibration or broken.
