[新品] 进口限流止回阀 限制水泵流量逆止阀

品牌：RETZ瑞茨/美国，我们一直致力于流体控制领域的持续创新，始于2005……

性能：限制水泵工作流量，防止水泵过载，停泵时回流的作用

Performance: Limit the working flow of the water pump, prevent overload of the water pump, and prevent backflow during pump shutdown

产品详情 Product details

限流止回阀主要用于多泵并联且采用改变台数的方式进行流量调节的供水系统中，它安装在水泵的出口，能起限制水泵流量、稳定扬程的作用，可使水泵工作在高效区内，防止低扬程大流量水泵过载烧坏电机。同时该阀还具有止回缓闭功能，能显著减小水锤。

The flow limiting check valve is mainly used in water supply systems where multiple pumps are connected in parallel and flow is adjusted by changing the number of units. It is installed at the outlet of the water pump, which can limit the flow of the water pump and stabilize the head. It can make the water pump work in an efficient area and prevent the low head and large flow water pumps from overloading and burning the motor. At the same time, the valve also has a check and slow closing function, which can significantly reduce water hammer.

进口限流止回阀结构特点 Structural characteristics

1.限流功能：安装于水泵出口，在单泵启动和非全数设计工作时，多工作泵起限制流量作用 2.泵在较高效率状态下工作：防止电动机受水泵低扬程、大流量、低效率时，发生过载现象 3.防止超额定电流烧电机现象的发生，同时起到一定的节能效果

4.止回功能，该阀的止回功能完全等同于微阻缓闭止回阀，且无关闭噪音，零回流。此阀主要用于多泵并联使用时安装与水泵压出口，起限制水泵工作流量，防止停泵回流作用 Check 5.限制扬程可调范围0.1-0.6 Mpa，出厂时设定在0.1 Mpa
