Product Description
The air valve is a special valve designed to prevent transient decompression waves from producing negative pressure in the tube.It is usually installed in the normal operation of the pipeline when the hydrodynamic pressure is low, transient flow process, there may be liquid column separation high point position.Air is drawn in when the pressure in the pipe is lower than atmospheric, and is expelled when the pressure in the pipe rises higher than atmospheric.During venting, the valve can be closed automatically when the pipe is filled with liquid, which is not allowed to escape into the atmosphere.

空气阀是一种特殊的阀，用于防止瞬态减压波在管道内产生负压。它通常安装在正常运行的管路中，当动水压力较低、流动过程呈瞬态时，可能会出现液柱分离高点的位置。当管道中的压力低于大气时，空气被吸入，当管道中的压力高于大气时，空气被排出。排气时，当管道内充满液体时，阀门自动关闭，不允许液体泄漏到大气中。

Application
The single-port air valve is used for exhaust in independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Because there is usually a certain amount of air dissolved in the water, and the solubility of the air decreases with the increase of temperature, in this way, in the process of water circulation, the gas gradually separates from the water and gradually gathers together to form large bubbles or even gas columns. Because of the supplement of water, there are often gases produced

单孔气阀用于独立采暖系统、集中采暖系统、供暖锅炉、中央空调、地暖、太阳能采暖系统的排风。因为通常有一定量的空气溶解在水中,和空气的溶解度随温度的增加而减小,这样,水循环的过程中,气体逐渐从水中分离甚至逐渐聚集在一起形成大气泡或气列。由于水的补充，经常会产生气体。
