Ductile iron composite exhaust valve CARX-16Q

CARX-16Q composite exhaust valve is used for the highest point on the pipeline or a closed air place, remove the gas in the pipe to dredge the pipeline to achieve normal operation, such as not installing the exhaust valve, the flow of liquid in the pipe to generate kinetic heat caused by the gas, the formation of short-circuit, so that the pipeline out of the capacity of the water can not meet the requirements, and secondly, the pipeline operation of the power outage, stopping the pump pipeline will be a negative pressure, which will cause vibration or rupture of the pipeline, the exhaust (suction) valve will quickly suck the air into the pipe, preventing pipeline vibration or rupture, the exhaust (suction) valve. The exhaust (suction) valve quickly sucks air into the pipe to prevent pipe vibration or rupture.

Working Principle

At the stage of water injection into the pipeline, a large amount of gas rushes into the composite exhaust valve. At this time, the large hole exhaust port in the valve opens quickly to realize rapid exhaust. As the water level in the pipeline rises, the gas pressure increases, and the small hole exhaust port begins to work, discharging a small amount of gas. When the pipeline is full of water and the gas is basically discharged, the float rises under the action of buoyancy and closes the exhaust port to prevent water leakage.

Work Characteristics

• High-efficiency exhaust: Equipped with two types of exhaust ports, large and small, it can adapt to different exhaust needs and realize high-efficiency exhaust.
• Stable sealing: high-quality sealing materials and reasonable structural design ensure good sealing performance and avoid medium leakage.
• Durable and reliable: Made of high strength materials, it can withstand pressure and temperature changes in the piping system and has a long service life.

Application Areas

Widely used in urban water supply, fire fighting, HVAC and industrial piping systems, effectively guaranteeing the stable operation of the system.

Installation and Maintenance

Attention should be paid to the installation direction and position to ensure the exhaust effect. Regularly inspect and maintain the exhaust valve, clean the internal impurities and check the wear and tear of the sealing parts to ensure its normal operation.
