Operating Principle of Air Release Valve

Operating Principle of Air Release Valve

Air release valve is also called air release valve. It is a kind of valve commonly used in the installation of water heating. It is generally installed at the highest point of the system. It is often seen on the radiator and water separator.

There are two kinds of manual air release valve and automatic air release valve. The former needs to be operated manually and closed manually after air release, which is quite troublesome. The manual air release valve has gradually faded out of the market, and the latter can automatically release air at any time. Most of the new buildings use or automatic air release valve. In the process of water replenishment, there will be gas entering the heating pipe. When the gas is congested, the heating will not be hot Set or air release valve to let off gas and make heating system circulate smoothly.

Function principle: when the water enters the pipeline, the plug head stops at the lower part of the positioning frame to exhaust a lot of air. When the air is exhausted, the water enters the valve to float the ball, and the plug head is driven to close to stop the exhaust. During the normal operation of the pipeline, a small amount of gas will naturally be generated, which will gather in the upper part of the pipeline. To a certain extent, the water level in the valve will drop, and the gas will be discharged from the small hole along the water falling of the floating ball. In case of power failure and pump stop, the negative pressure will appear at any time when the water in the pipeline flows empty, and the floating ball will drop along the water. Open the small hole to drive the large hole to conduct a large amount of air intake to ensure the safety of the pipeline.
