結(jié)構(gòu)及用途 Structure and purpose

該閥主要安裝于水池或水塔的進(jìn)口處，當(dāng)水位達(dá)到設(shè)定高度時，主閥由浮球?qū)чy控制關(guān)閉進(jìn)水口停止供水，當(dāng)水位下降后，主閥由浮球?qū)чy開關(guān)控制打開進(jìn)水口向水池或水塔供水，實現(xiàn)自動補(bǔ)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(hù)、調(diào)試、檢查方便、使用壽命長(浮球?qū)чy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)．
