GLH45H沟槽式限流止回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。

Product Features

  • 支持水泵工作点在高效区内工作。
  • 限制水泵在大流量低效率状态下运行。
  • 关闭时无水锤现象。
  • 防止水泵过载烧环电机。
  • 无级调节扬程功能。

Working Principle

  1. 沟槽式限流功能该阀安装于水泵出口,在单泵启动和非全数设计工作泵工作时,多工作泵起限制流量作用,使泵在较高效率状态下工作;防止电动机爱水泵低扬程、大流量、低效率时,发生过载现象;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。其限流原理为:依据水泵的设计工况扬程,导阀自动检测并控制水泵的实际工作扬程,以限制水泵的工作流量,限制电机的负载。该阀设定一个控制工作气扬程,当水泵工作扬程低于控制扬程时阀门做关阀动作,使实际工作扬程加大;当水泵工作扬程大于设定扬程时阀门全开,阀门阻力极小。控制气扬程的设定可以按电机额定电流设定,也可以按高效率工况设定,该阀门工作扬程设定值可调,一般出厂设定值为设计工况扬程。
  2. 止回功能:该阀的止回功能完全等同于微阻缓闭止回阀,且无关闭噪声,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。该阀采用导阀-主阀构造,结构紧凑,重量较轻。
