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.


空氣閥是一種用于防止瞬態(tài)減壓波在管道內(nèi)產(chǎn)生負壓的專用閥。它通常安裝在管道正常運行時流體動壓較低，瞬態(tài)流動過程中，可能存在液柱分離高點的位置。當管道內(nèi)的壓力低于大氣時，空氣被吸入，當管道內(nèi)的壓力高于大氣時，空氣被排出。在排氣過程中，當管道中充滿液體時，閥門可以自動關(guān)閉，不允許液體逸到大氣中。

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
