When does the exhaust valve heat up?

The heating exhaust valve allows users to release bubbles generated in the heating system and water supply pipeline, which is suitable for use in the northern region with harsh climatic environment. Widely used in water separators, radiators and floor heating.

Working principle:

When gas is generated in the system, due to its low density, the gas will climb up along the pipeline, and the final gathering is at the highest point of the system. So the exhaust valve is generally installed at the highest point of the system. When the gas enters the valve cavity of the exhaust valve and gathers at the upper part of the exhaust valve, the pressure rises with the increase of the gas in the valve. When the gas pressure is greater than the system pressure, the gas will make the water level in the cavity drop, the buoy will drop with the water level, and the exhaust port will open. After the gas is exhausted, the water level rises, the buoy also rises, and the exhaust port closes.
