Exhaust valve <large-diameter exhaust valve> is applied to pipeline exhaust such as independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system. Because the water usually dissolves in a certain amount of air, and the solubility of the air decreases with the increase of temperature, the gas gradually separates from the water during the process of circulation, and gradually gathers together to form large bubbles or even gas columns. Because of the supplement of water, there are often gases. For this reason, the term "exhaust valve" has been extended, and many problems have been solved in daily life.
