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.

空氣閥是一種特殊的閥，用于防止瞬態減壓波在管道內產生負壓。它通常安裝在正常運行的管路中，當動水壓力較低、流動過程呈瞬態時，可能會出現液柱分離高點的位置。當管道中的壓力低于大氣時，空氣被吸入，當管道中的壓力高于大氣時，空氣被排出。排氣時，當管道內充滿液體時，閥門自動關閉，不允許液體泄漏到大氣中。

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

單孔氣閥用于獨立采暖系統、集中采暖系統、供暖鍋爐、中央空調、地暖、太陽能采暖系統的排風。因為通常有一定量的空氣溶解在水中,和空氣的溶解度隨溫度的增加而減小,這樣,水循環的過程中,氣體逐漸從水中分離甚至逐漸聚集在一起形成大氣泡或氣列。由于水的補充，經常會產生氣體。
