產品簡介：
遙控浮球閥一般分為隔膜閥和活塞閥兩大類，本公司生產的遙控浮球閥口徑在DN500mm以下者采用隔膜型，口徑在DN600mm以上者采用活塞型，兩者之動作原理類似。遙控浮球閥能有效地控制水箱或水塔液面，適時地切斷或打開閥芯輸入水流或阻止水流外泄。液位控制準確，水位不受壓力波動干擾，關閉緊密不漏水，浮球靈活，維護保養方便簡單。廣泛適用于工礦、企業、高層建筑中的水箱、水池、水塔的自動供水系統。
Products Introduction:
Remote float control valves are usually divided into diaphragm valves and piston valves two categories, the caliber of the company’s production bellows DN500 using diaphragm type, and DN600 more in the use of piston type, whichever is the principle of similar moves. Remote float control valves can control the level effectively of the water tanks and the water towers, timely cut or open the input current of the heart valve or to stop the current leaks. Level control nicety, water level can’t be disturbed by the pressure fluctuation, close doesn’t leak, float boll is flexible, maintenance is convenient and simple. Widely used in the automatic water supply system of the water tanks、pond and water towers which used in the mine、enterprise and tall building.
