用途 User

可控制水塔或水池的液面。适用于工矿企业、民用建筑中各种水池（箱）、水塔的自动供水系统。

Can control the liquid level of water tower or sink. It is suitable for automatic water supply system of various pools (boxes) and water towers in industrial and mining enterprises and civil buildings.

特点 Characteristic

阀体采用了全通道流线型设计，流量大，密封效果好，保养简单，灵活耐用，液位控制准确度高，水位不受水压干扰且关闭紧密不漏水。

The valve body adopts the full-channel streamline design, the flow is large, the sealing effect is good, the maintenance is simple, flexible and durable, the liquid level control accuracy is high, the water level is not disturbed by the water pressure and close not leaking.

原理 Principle

主阀上腔与控制用浮球阀相连，浮球阀固定于水箱液面处。水箱液面下降浮球阀打开，主阀打开，向水箱供水；当液面升至浮球阀位置时，浮球阀关闭，主阀随之关闭，停止向水箱供水。

The upper chamber is connected to the control with the float valve and the ball valve is fixed to the tank level. The water tank level drops float ball valve opens, main valve opens, water supply to water tank; When the liquid level reaches the float valve position, the float valve is closed, the main valve is closed and the water tank is stopped.
