Features of exhaust valves

When there is air in the system, the gas gathered in the upper part of the exhaust valve, gas accumulation in the valve, the pressure rises, when the gas pressure is greater than the system pressure, the gas will make the water in the cavity down, the float with the water level down, open the exhaust port; gas exhaust, the water level rises, the float rises, close the exhaust port, such as tightening the valve cap on the valve body, the exhaust valve to stop exhausting, usually, the cap should be in an open Normally, the bonnet should be open. It can also be used together with the isolation valve to facilitate the maintenance of the exhaust valve.
1. The float of the exhaust valve is made of low-density PPR and composite material, which will not be deformed even if it is immersed in high-temperature water for a long time. This material will not cause the float to be difficult to move.

2. The lever of the float is made of hard plastic, and the connection between the lever and the float and the support are all movable, so it will not produce corrosion during long-term operation, which will cause the system not to work and water leakage occurs.

3. The sealing end part of the lever is supported by a spring, which can be expanded and contracted accordingly with the movement of the lever to ensure the sealing in the case of non-venting.

4. When the exhaust valve is installed, it is best to install it together with the isolation valve, so that when the exhaust valve needs to be removed for maintenance, it can ensure that the system is airtight and the water will not flow out. Low-density PP material, this material even if long time in high temperature water immersion will not produce deformation.
