An overview of sewage composite exhaust pneumatic valve 2)

gas drainage pipe pneumatic valve compounds on the road or in the breath, take out the gas pipeline dredge pipe, the highest point of the work, if not installed exhaust pneumatic valve, liquid flow line of aerodynamic force and thermal electricity form the short-circuit capacity of the pipeline is mainly caused by the water, power through the pipeline operation stop negative pressure pump pipe, this can lead to pipeline vibration or broken, ( Suction) Pneumatic valve of air inlet pipe, prevent the pipeline vibration quickly second or rupture.
how it works:
when water injection pipe, plug head stays in the open position, a large amount of waste gas, drainage, pneumatic valve, when the water by the, floating plug head to air in the closed position, to stop a lot of waste gas; When the normal water pipe delivery time, if the air vent pneumatic valve inside a small amount of gathered in a great extent, pneumatic valve, water levels fall float down, this time from a small hole in the air. When the pump stop, flow pipe empty, or when the tube under the condition of negative pressure, and then open the plug head, inhalation of air, to ensure the safety of pipeline. Application:
. Medium: water. Temperature: room temperature. Body: cast iron HT. Float and stopper: stainless steel. Sealing material: nitrile rubber. Test inhibition: of the organization. The MPa. , floating seal test, and to suppress:. - 。 MPA watertight
features: the main stainless steel ball float water mixed exhaust pneumatic valve body and internal plug drum. This pneumatic valve installed in the pump Song Peipu water pipes, ruled out exports a large number of air pipe assembly, water pipes and pumps, in order to improve the efficiency, and the pipe pressure, the pneumatic valve can quickly inhaled air pressure resulting from damage to the cable.
