Automatic exhaust valve Introduction: heating system and HVAC system during operation, the water released during heating gas (such as hydrogen, oxygen, etc.) the many adverse effects of damage to the system and reduce the thermal effects of these gases, such as not Timely discharge will have a lot of adverse consequences. Such as: corrosion caused by oxidation; the formation of airbags in the radiator; unbalanced hot water circulation is not smooth, so that some radiators do not partially heat; noise when the pipe runs with gas; vortex phenomenon circulating pump. This shows that the use of automatic exhaust valve an important role. The new automatic vent valve design takes into account all the known disadvantages, such as impurities in the water, oil, suspended solids, turbulence in the valve liquid during venting, vibrations in pipes and equipment connected to the vent valve, and more. ) Excellent performance: Reliable operation no matter whether the system has just been filled with water (a large amount of gas is discharged when the system is operating), or when the system pressure is too high, it requires proper drainage and pressure relief. First, the exhaust valve features: 1. Reliable performance. Exhaust valve exhaust mechanism is very reliable, at the factory before each valve through the exhaust test and pressure seal experiment. Individual components are cast from high precision, resulting in a perfect fit. 2. Easy to maintain. Automatic venting is fitted with a shut-off valve that allows easy removal of the vent valve from the system for maintenance while the water in the system will not flow out, so there is no need to empty the system. 3. Only exhaust, no drainage. Steam, water disc design using a special structure to ensure that when the exhaust is not drained. 4. As long as the system is under pressure, the exhaust valve will continuously exhaust. Second, the main purpose: Automatic exhaust valve for: independent heating system; central heating system; radiant floor heating system; solar heating system; heat pump system; central air conditioning; heating boiler Third, the principle of automatic exhaust valve When the system When there is air, the gas collects in the upper part of the exhaust valve. The accumulation of bubbles in the body causes the float to drop with the water level, thus opening the exhaust piston. After the exhaust gas is exhausted, the water level rises and the float rises, closing the exhaust piston. If tightening the bonnet on the side of the body, the vent valve stops venting, and normally the bonnet should be open.
