一、结构及用途 Structure and purpose

      该阀主要安装于水池或水塔的时口处 ,可精确定制液位范围,当液位达到上限或下限时,会发出信号报警,同时将阀开启或关闭.

     该阀安装在水池或水塔液上限处 ,液位控制精度高(二道保卫)防止溢流,不受水压扰,可任意安装位置,密封性能可靠,安装、维护、调试、检查方便，使用寿命长，并可根据用户要求在任意设定控制范围。

This valve is mainly mounted at the inlet of a water pool or a water tower and can accurately control the liquid level range and, when the level gets to the upper or lower limit,send out a signal for alarming and open or close the valve at the same time.

This valve is mounted at the liquid level upper limit of a water pool or tower, holds a high accuracy on the liquid level control (double-way guard) and prevents overflow. With-out being subject to the water pressure disturbance, mountable at any position, reliable sealing performance, easy installation, maintenance, adjustment and check, long duration,and the control range can be set at will upon the user requirement.
