結構及用途 Structure and purpose
該閥主要安裝于水池或水塔的時口處 ,可精確定制液位范圍,當液位達到上限或下限時,會發出信號報警,同時將閥開啟或關閉。
該閥安裝在水池或水塔液上限處 ,液位控制精度高(二道保衛)防止溢流,不受水壓擾,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，并可根據用戶要求在任意設定控制范圍。
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.
