Quick Details
Specifications
Silent check valve main body, seat, diversion body, valve, springs and other parts flow channel is designed to streamline and effectively over an area equivalent to the valve nominal diameter, flow losses are small; valve stroke short, under the action of the spring assisted to achieve fast closed, the quick-closing action to effectively prevent the generation of water hammer, to achieve quiet operation pipeline.
compound exhaust valve has a barrel-shaped body, containing the stainless steel floating ball, lever and valve flap inside. The valve is installed in the pump outlet or water distribution pipelines to discharge the air trapped in the pipe so as to improve the efficiency of the pipeline and pump operation, which can quickly intake air from outside once negative pressure is present in the pipe to prevent it from damage due to the negative pressure. At the start of water filling in the pipe, the valve flap is in the open position to discharge the air at a big flow rate; when the air discharge is finished, the valve is filled with water, so the floating ball rises up to make valve flap be closed and stop the air discharge; during the normal water conveyance in the pipe, If a small amount of air accumulates gradually in the valve, the water level of the valve will drop, then the air will be discharged through the small hole when the level is low enough. When the pump is stopped, the water flows away or negative pressure is generated in there, the plug will open rapidly to intake air, which ensures the pipeline safety. Medium temperature: 0 ~ 80 ℃.
