Product details

CARX compound exhaust valve principle of action :
 When the tube began to inject water, the stopper stuck in the open position, a lot of exhaust, when the air row is exhausted, the valve floats float, drive plug to the closed position, Stop a lot of exhaust; when the tube of water during normal delivery, if a small amount of air gathered in the valve to a considerable extent, the valve water level drops, the float drops, then the air is discharged from the hole. When the pump stops, the water flow in the tube is empty, or when negative pressure is generated in the tube, the plug is turned on at this time and the air is sucked in to ensure the safety of the pipeline.


Structure and use:
 CARX composite exhaust valve is a barrel-type valve body, a total of the main internal stainless steel float ball and plug. 
 The CARX compound exhaust valve is installed at the outlet of the pump or sent to the water distribution pipeline to eliminate the air in the pipeline to increase the efficiency of the water pipe and the water pump. When the valve is in negative pressure with the pipe Rapidly inhale the air to protect the line from damage due to negative pressure.
