PRODUCT INTRODUCTION
1. Description
CARX compound exhaust valve is used at the highest point of the pipeline or at the place where the air is closed. It expels the gas in the pipeline to dredge the pipeline and achieves normal work. If the exhaust valve is not installed, the liquid flowing in the pipeline generates dynamic heat which causes the gas to form a short circuit and makes the outlet capacity of the pipeline fall short of the requirement. Secondly, power cut and shutdown occur when the pipeline is running. Pump pipe will appear negative pressure, and will cause pipe vibration or rupture, exhaust (suction) valve on the rapid suction of air into the pipe, to prevent pipe vibration or rupture.
2. Principle of compound exhaust valve
When water is injected into the pipe, the plug stays in the open position and exhausts a lot. When the air is exhausted, the floating ball in the valve is floated, and the driving plug stops exhausting a lot. When the water in the pipe is conveyed normally, if a small amount of air gathers in the valve to a certain extent, the water level in the valve drops and the floating ball goes down. The air is discharged by small holes. When the pump stops, the water in the pipe is empty, or when there is negative pressure in the pipe, the plug opens and the air is sucked in to ensure the safety of the pipeline.
3. Structure and application of compound exhaust valve
The CARX compound exhaust valve is a barrel shaped valve body, which consists of stainless steel floating balls and plug heads.
CARX composite exhaust valve is installed at the outlet of Pump Po or in the water supply and distribution pipeline to remove a large amount of accumulated air from the pipeline, so as to improve the efficiency of the water pipe and pumping unit. In case of negative pressure in the pipeline, the valve can quickly suck in air to protect the pipeline from damage caused by negative pressure.
