| High Light | Compound Water Valve ，Water Valve High Speed ，High Speed Exhaust Valve | ||
The composite exhaust valve is used at the highest point on the pipeline or at the place with closed air to exhaust the gas inside the pipeline and clear it. The pipeline can achieve normal operation. If no exhaust valve is installed, the liquid flowing inside the pipeline will generate dynamic heat and cause gas. Forming a section of the pipeline to ensure that the water output meets the design requirements. Secondly, there is a power outage or shutdown during the operation of the pipeline Negative pressure in the pump pipeline can cause pipeline vibration or rupture, and the exhaust valve quickly sucks air into the pipeline,
Prevent pipeline vibration or rupture.
Features:
Performance:
Under no water or pressure, both the float and valve disc fall into the casing. When the pipeline is filled with water, a large amount of air is discharged from the large exhaust port. As the air is almost exhausted, water begins to enter the valve and float it up. The float then lifts the valve disc, blocking the large exhaust port and preventing water from flowing out. After the valve disc blocks the large exhaust port, as long as the water and gas in the pipeline are under pressure, the valve disc will not fall. At this point, if the air in the pipeline accumulates to a certain amount in the exhaust valve, it will fall down due to the reduced buoyancy of the float, and the air will be discharged from the small exhaust hole of the guide rod. After the air is exhausted, the float rises again to block the small exhaust hole. When negative pressure is generated in the pipeline, both the valve disc and float are sucked down, and a large amount of air is replenished from the large exhaust port.
Application:
The compound exhaust valve is used for pipe exhaust of independent heating system, central Hydronics, heating boiler, central air conditioning, floor heating and solar heating system. Because water usually contains a certain amount of air, and the solubility of air decreases with the increase of temperature, gas gradually separates from the water during the circulation process and gradually accumulates to form large gas
Bubbles and even gas columns often generate gas due to the addition of water. The appearance of the exhaust valve effectively solves this problem
