Brass Air Valve is used for duct exhaust equipment such as independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system
Brass exhaust valves are used in pipeline exhaust of independent heating systems, central heating systems, heating boilers, central air conditioning, floor heating and solar heating systems. Because there is usually a certain amount of air dissolved in water, and the solubility of air decreases with the increase of temperature, the gas is gradually separated from the water during the circulation of water, and gradually gathers together to form large bubbles or even gas columns. Because of the supplementation of water, gas is often produced.
Working Principle :
In the exhaust state, the buoy pulls down one end of the lever due to the action of gravity. At this time, the lever is in a tilted state. There is a gap in the contact part between the lever and the exhaust hole, and the air is discharged from the exhaust hole through this gap. The water level rises, the buoy floats up under the action of the buoyancy of the water, and the sealing end face on the lever gradually presses the exhaust hole until the entire exhaust hole is completely blocked. The exhaust valve is now completely closed. This type of valve should generally be installed horizontally in the pipeline.
Features :
1. The float of the copper exhaust valve is made of low-density PP material, which will not deform even if it is immersed in high temperature water for a long time. It will not cause difficulty in buoy movement.
2. The buoy lever is made of hard plastic, and the connection between the lever and the buoy and the support adopts a movable connection, so there will be no corrosion during long-term operation, which will cause the system to fail to work and cause water leakage.
3. The sealing end face of the lever is supported by springs, which can expand and contract with the movement of the lever to ensure the sealing performance without exhausting.
Precautions :
1. Uneven temperature in some parts
2. Make noise.
3. The oxygen contained in the air is the main cause of metal corrosion.
4 Too many air bubbles can also cause damage to the pump.
5. Because the water pipeline is thin and the layout of the water pipeline in the unit is complicated, gas collection often occurs and the flow protection phenomenon occurs.
Therefore, for the water pipeline system, we must pay attention to the exclusion of air. The system must have adequate exhaust valves installed to vent the air. A good exhaust valve not only has high exhaust efficiency, but also does not discharge water
