"Automatic Exhaust Valve" Instruction Manual I. Product Overview Many of the adverse effects of the gas (such as hydrogen, oxygen, etc.) released by the water during the operation of the gas and HVAC systems can damage the system and reduce the thermal effect , These gases can not be discharged in a timely manner will have many adverse consequences.
Such as: corrosion caused by oxidation; radiator in the formation of airbags; hot water circulation is not smooth unbalanced, so that some of the radiator is not hot; pipe with gas when running noise; circulation pump vortex phenomenon.
This shows the important role of the use of automatic exhaust valve.
The new vent valve design of Shanghai Huhang Copper Valve Manufacturing Co., Ltd. takes into account all the unfavorable factors known (such as impurities in water, oil, suspended solids, etc.) turbulence of the liquid in the valve when the exhaust is exhausted; The connection of pipes and equipment, etc.) has excellent performance: whether it is in the system just after the water to run (the system just run a large number of gas discharge.) Or the system pressure is too high to moderate drainage pressure relief, can Reliable operation.
Second, the product features 1.
Reliable performance.
Discharge device materials using PK-EP.
Compared with all known synthetic materials, PK-EP has the best performance and highest reliability.
PK-EP can withstand high temperatures (much higher than the operating temperature of the exhaust valve.)
O-ring using optimized material EPDM, to ensure that the high temperature O-ring still has good flexibility and operational reliability.
The internal spring of the exhaust valve spool is made of special material and is nickel-plated stainless steel to prevent oxidation (if the oxidation affects the movement of the spool); the exhaust mechanism of the exhaust valve is very reliable and every valve is passed at the factory Exhaust test and pressure seal test.
Body and bonnet with HPb59-1 brass hot forging, high-quality components made of brass, resulting in a perfect assembly.
2.
Easy maintenance.
Automatic exhaust is fitted with H18 block valve, H18 block valve allows easy removal of the exhaust valve from the system for maintenance, and the system will not flow out of water, so do not emptying the system.
3.
Only exhaust, no drainage.
Steam, water separation disk design using a special structure to ensure that the exhaust will never drain.
4.
As long as the system pressure, the exhaust valve will continue to exhaust.
Third, the main purpose Automatic exhaust valve for: independent heating system; central heating system; floor radiant heating system; solar heating system; heat pump system; central air conditioning; heating boilers.
Fourth, the working principle of automatic exhaust valve When the system has air, the gas gathered in the upper part of the exhaust valve, the body bubble accumulation so that the float with the water level, so open the exhaust piston; gas exhausted, the water level rise, floating The ball also rises and closes the exhaust piston.
Such as tightening the valve body side of the bonnet, exhaust valve to stop the exhaust, in general, the bonnet should be open.
