Single-port exhaust valve

Single-port EXHAUST valve (exhaust valve) is used for pipe exhaust of independent heating system, central heating system, heating pot furnace, central air conditioning, floor heating and solar heating system. Because water is usually dissolved with a certain amount of air, and the solubility of air decreases with the increase of temperature, so that in the process of water circulation, the gas gradually separates from the water, and gradually gathers together to form large bubbles or even gas columns. Because of the water supplement, there are often gas produced.
Single-port exhaust valve Features:
Stand-up exhaust valve is mainly composed of body, cover, stem, floating ball, and other components of the exhaust mouth, divide into two kinds exhaust valve, flange and thread is suitable for small diameter pipe on the pipe for phi 15-80, as the exhaust pipe, the pipe will not appear breath, air resistance, such as tube pumps of a power failure at any time there will be a negative pressure, automatic suction can protect the security of the pipeline.
Working principle of single-port exhaust valve:
When need gas discharge pipe, air in the pipe under the action of water pressure into the cavity, and is discharged from exhaust nozzle, the water in the pipe then filled with cavity, the float ball under the effect of the buoyancy of water, the movement will exhaust nozzle clogging up, achieve self sealing, pipeline in the normal line, the air in the water under the action of the pressure, constantly into the exhaust valve body cavity of the upper, Force the floating ball down, leave the original sealing position, then the air is discharged from the exhaust nozzle, then the floating ball returns to the original position of self-sealing, therefore, the exhaust valve is always open in the normal work, the floating ball continues to repeat the above action, the air is discharged. When it is necessary to overhaul or clean the body cavity, the valve should be closed.
