How to exhaust the automatic exhaust valve
The automatic exhaust valve is an important component in the heating system, air conditioning system or pipeline system. It is mainly used to remove the air in the pipeline to ensure the normal operation of the system. This article will introduce in detail the working principle, exhaust method and common problems of the automatic exhaust valve, and provide practical reference based on the hot topics and hot content on the Internet in the past 10 days.
1. Working principle of automatic exhaust valve

The automatic exhaust valve senses the amount of air in the pipeline through a float or spring mechanism. When the air accumulates to a certain level, the valve automatically opens to exhaust, and automatically closes after exhausting the air. Its core function is to prevent air lock and improve system efficiency.
| Part name | Function |
|---|---|
| Float | Sensing air volume and controlling valve opening and closing |
| exhaust port | Remove air from ducts |
| gasket | Prevent water leakage and ensure the valve is sealed when closed |
2. Exhaust method of automatic exhaust valve
1.Automatic exhaust: Under normal circumstances, the valve will automatically exhaust according to air accumulation without manual intervention.
2.Manual exhaust: If the automatic exhaust valve fails, it can be operated manually:
| Exhaust method | Applicable scenarios |
|---|---|
| Automatic exhaust | The system is operating normally and the valve is faultless |
| Manual exhaust | Valve clogged or automatic function failed |
3. Common problems and solutions
1.Exhaust valve leaking: The sealing gasket may be aged or damaged and needs to be replaced with a new gasket.
2.Exhaust valve does not exhaust: Check whether the float ball is stuck, clean the impurities or replace the valve.
3.Frequent exhaust: There may be air leakage points in the system, and the pipe sealing needs to be checked.
| question | Reason | Solution |
|---|---|---|
| water leakage | Damaged gasket | Replace gasket |
| No exhaust | float stuck | Clean or replace float |
| Frequent exhaust | System leaks | Check pipe seals |
