Background

The exhaust valve is applied to exhaust of pipelines such as an independent heating system, a centralized heating system, a heating pot, a central air conditioner, a floor heating system, a solar heating system and the like. Because water usually has some dissolved air, and the solubility of air decreases with increasing temperature, the gas gradually separates from water during circulation and gradually gathers together to form large bubbles and even gas columns, and because of the supplement of water, gas is often generated. When gas overflows from the system, the gas climbs upwards along the pipeline and finally gathers at the highest point of the system, the exhaust valve is generally installed at the highest point of the system, and when the gas enters the valve cavity of the exhaust valve and gathers at the upper part of the exhaust valve, the exhaust valve starts to exhaust along with the increase of the gas in the valve.

In the prior art, the sealing end face of the lever of the exhaust valve is generally supported only by the spring, although the sealing end face can be correspondingly contracted along with the lever, and the sealing performance is ensured under the condition of no exhaust, when the air pressure is increased steeply, the lever rapidly pulls the spring, so that the spring is easy to fall off from the sealing end face, and the exhaust function of the exhaust valve is further failed.

In order to solve the problem, an intelligent exhaust valve is provided in the application.
