The automatic exhaust valve is used as a functional exhaust valve for automatically exhausting air in a system, and is widely applied to heating and ventilation systems such as central air conditioners, central heating, solar heating and the like. When gas exists in the heating and ventilation system, the gas moves upwards along the pipeline and finally gathers at the highest point of the system, so that the automatic exhaust valve is generally arranged at the highest point of the system.

The automatic exhaust valve consists of valve body, valve rod, float bowl, dust cap and other parts. When the gas pressure is higher than the system pressure, the float falls down to drive the valve rod to move downwards, the valve port is opened, and the gas is discharged; when the gas pressure is lower than the system pressure, the float bowl rises to drive the valve rod to move upwards, and the valve port is closed. The automatic exhaust valve realizes automatic exhaust of system air based on the change of gas pressure.

However, in actual operation, due to the influence of factors such as water quality of the system, the valve port of the automatic exhaust valve is often blocked by impurities and cannot be completely closed, so that the automatic exhaust valve leaks water.
