一、結構及用途 Structure and purpose

該閥主要安裝于水池或水塔的進口處，當水位達到設定高度時，主閥由浮球導閥控制關閉進水口停止供水，當水位下降后，主閥由浮球導閥開關控制打開進水口向水池或水塔供水，實現自動補水。

該閥液位控制精度高，不受水壓干擾，可任意安裝位置，密封性能可靠，安裝、維護、調試、檢查方便、使用壽命長(浮球導閥可與主閥分離安裝)。

Installed on the inlet of a water pool or tower．The main valve is controlled by the floating pilot valve to close the inlet to stop water supply when the water level gets to the set height and to open the inlet t0 supply water to the water tower or pool so as to realize the automatic water supplement when the water level lowers It features a high accuracy of level control．water pressure disturbance resisting。mountable on any positions，reliable seal performance,easy installation，maintenance，debugging and check，long duration(The floating pilot valve can be separately mounted from the main one)．

四、主要外形及連接尺寸 Schematic diagram of installation

注：安裝示意圖中彈性座封閘閥或蝶閥任選，建議≥DN350選蝶閥。
Note：Either elastic seat ring sealed gate valve or butterfly valve can be selected in the schematic diagram of installation.Recommended to select the butterfly valve in case of≥DN350.
