CARX composite exhaust pneumatic valve structure and working principle

CARX composite pneumatic valve exhaust vent pneumatic valve is the most commonly used in China, it's on the ball float and floating ball lever exhaust pneumatic valve is modified on the basis of the combination. Under the stress state of trace exhaust with floating ball lever type exhaust; For the first time or other cases of filling water into the exhaust with ball float device. Can increase the dimension of the into the vent, into the exhaust velocity have greatly improved.
CARX composite exhaust pneumatic valve pneumatic valve body for round barrel, pneumatic valve internal parts including stainless steel ball, pneumatic valve stem and disc. This pneumatic valve is installed in the pump outlet or send water distribution pipeline, set is used to eliminate the air in the tube, to improve the efficiency of the use of the pipeline and water pump, when once produced negative pressure tube, the pneumatic valve quickly inhaled air outside, in order to prevent the pipeline damage due to negative pressure.
when tube began to water injection, pneumatic valve is in open position, a large number of exhaust, when the air line up, the full of water in the pneumatic valve, floating ball up and drive the pneumatic valve closed, stop the exhaust, when water tube is normal transportation, if there is a small amount of air gathered to reasonably in the pneumatic valve, pneumatic valve inside the water levels fall, floating ball drops, the air is being exhausted from the holes. When the pump stops, the tube water empty or negative pressure in the tube, the plug head quickly open, inhalation of air, to ensure pipeline safety.
how it works:
the main is to use the water to float the buoyancy effect, when the exhaust pneumatic valve water level rise, in with the exhaust, floating to the buoyancy of water function, the automatic buoyancy, until the sealing surface with the vent, to a certain pressure ball will automatically shut down, when reduced water levels in pneumatic valve, the club with the water level falls, then will be through the vent pipe pumping air, the pneumatic valve with pneumatic valve belong to automatic.
when system in gas overflow, gas will be along the pipeline social climbers, and eventually gathered at the highest point of the system, pneumatic valve is generally installed in the exhaust system is the highest point, when the gas into the exhaust air valve pneumatic valve cavity gathered in the upper portion of the exhaust pneumatic valve, along with the increase in gas inside the pneumatic valve, pressure rise, when gas pressure is greater than the system pressure, the gas can make the cavity of the water drops, buoy with water level drops, open the vent; Gas, after the water level rise, buoy also rose, close the vent. Likewise, when negative pressure is formed in system, pneumatic valve chamber in the water drops, vent open, because the outside atmospheric pressure is greater than the system pressure, so the atmosphere through the vent into the system, avoid the harm of negative pressure. Such as body tighten vent pneumatic valve pneumatic pneumatic valve cap, exhaust pneumatic valve to stop the exhaust, under normal circumstances, pneumatic valve cap should be in an open position. Exhaust with partition pneumatic valve pneumatic valve can also be used, easy to exhaust pneumatic valve repair.
