　　产品详情 Product details

　　压低损快闭止回阀性能是起到止回和快闭的作用，无水倒流，水头损失小，防止水锤的产生，有效地提高供水安全可靠性。同时本阀还设有流量调节装置，随时可以控制阀门的流量，必要时也可以手动关闭。

　　The performance of the Y-type quick closingcheck valve is to serve as a check and quick closing function, with no waterbackflow, small head loss, and the prevention of water hammer, effectivelyimproving the safety and reliability of water supply. At the same time, thisvalve is also equipped with a flow regulating device, which can control theflow of the valve at any time and can be manually closed if necessary

　　进口Y型快闭止回阀产品特点 Product Features

　　1.消除水锤、噪音：启闭与主阀瓣连锁动作，自动实现速闭，不受水泵流量、扬程波动影响。防水倒流，使停泵后的水锤压力减弱到zui低极限 Eliminating water hammer and noise: The opening and closing areinterlocked with the main valve disc, automatically achieving quick closure,unaffected by fluctuations in water pump flow and head. Waterproof backflow,reducing the water hammer pressure after stopping the pump to the minimum limit

　　2.节能效果显著：采用流线宽阀体、直流式设计，利用介质压力驱动无需外接动力，与进口同类产品相比，阻力损失降低50%以上 Significantenergy-saving effect: adopting a streamlined wide valve body and direct currentdesign, utilizing medium pressure to drive without external power, reducingresistance loss by more than 50% compared to imported similar products
