Air Release Valve How It Works

In the heating pipeline, a certain amount of air is usually dissolved in the water, and the solubility of the air decreases as the temperature increases, so that the gas is gradually separated from the water during the circulation of the water, and gradually gathers together to form large bubbles or even The gas column, because of the supplementation of water, often produces gas.

The existence of these gases can easily react with aquatic products, generate carbonic acid, corrode the inner wall of the radiator, and even cause the radiator to leak; The valve is to discharge these gases out of the pipeline in time to ensure the transfer of heat energy, which is the same as the discharge of the gas in the infusion tube by the medical staff.

The manual air release valve is a valve manually switched by the user, which discharges the gas from time to time; the Automatic Air Release Valve mainly uses the principle of air pressure, and the water in the pipeline after being installed in the heating system will flow into the valve automatically. The valve is in the closed state. Once air enters, the valve core shrinks naturally as the gas pressure increases, the air is discharged from the pipe through the valve core gap, and the valve core space is filled with water after the air is emptied. Due to the special structure of the valve core of the automatic air release valve, only air is allowed to be discharged without water drainage, so the purpose of automatic air release is achieved.
