(Summary description)The quick drain valve is suitable for pipelines that use water as the industrial medium. It is an indispensable equipment for pipelines to improve the efficiency of water delivery equipment and protect the pipelines from deformation and rupture. This valve is a barrel-shaped valve body with a stainless steel float and plug inside. The valve is installed at the outlet of the water pump or in the water supply and distribution pipeline to discharge a large amount of accumulated air in the pipeline to improve the use efficiency of the water pipe and the pump. In addition, once negative pressure occurs in the pipeline, the quick exhaust valve can quickly inhale air, thereby protecting the pipeline from damage caused by negative pressure.

The quick drain valve is suitable for pipelines that use water as the industrial medium. It is an indispensable equipment for pipelines to improve the efficiency of water delivery equipment and protect the pipelines from deformation and rupture. This valve is a barrel-shaped valve body with a stainless steel float and plug inside. The valve is installed at the outlet of the water pump or in the water supply and distribution pipeline to discharge a large amount of accumulated air in the pipeline to improve the use efficiency of the water pipe and the pump.

The quick exhaust valve is used for the exhaust pipes of independent heating systems, central heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems. Since water usually dissolves a certain amount of air, the solubility of air decreases as the temperature increases. The gas gradually separates from the water during the water cycle, and gradually gathers together to form large bubbles or even air columns. Due to the supplement of water, gas is often generated. So the term exhaust valve has been extended, and many problems have been solved in daily life.

  Quick exhaust valve working principle: In the exhaust state, the pontoon pulls down one end of the lever due to gravity, and then the lever is in an inclined state. There is a gap between the lever and the exhaust hole, and the air is discharged from the exhaust hole through this gap. As the air is discharged, the water level rises, the buoy floats up under the buoyancy of the water, and the sealed end face on the lever gradually presses on the exhaust hole until the entire exhaust hole is completely blocked, at which time the exhaust valve is completely closed.

Main features of    quick exhaust valve:

   1. It can eliminate the gas in the pipeline, reduce resistance and save energy.

  2. When the pipeline is under negative pressure, the product can quickly and automatically inhale air to prevent the pipeline from rupturing.

  3. The exhaust capacity is several times that of the ordinary double-hole exhaust valve.

  4. The float bracket is made of stainless steel, with long service life, safety and reliability.

Advantages of quick exhaust valve:

  1. The quick exhaust valve buoy is made of low-density PP material, which will not be deformed even if it is immersed in high temperature water for a long time, and it will not cause difficulty in the movement of the float.

  2. The buoy lever is made of hard plastic, and the connecting rods between the lever, the buoy and the bracket are all connected by movable connections, which will not corrode in long-term operation, and will not cause the system to fail to work and cause water leakage.

  3. The sealing end face of the lever is supported by a spring, which can expand and contract with the movement of the lever to ensure sealing performance without expelling air.
