產(chǎn)品詳情
產(chǎn)品簡介:
流量控制閥一般分為隔膜閥和活塞閥兩大類,本公司生產(chǎn)的流量控制閥口徑在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。流量控制閥設置在給水管線中。廣泛適用于工業(yè)給水、高層建筑由水泵直接給水系統(tǒng)中,調節(jié)流量。
Products Introduction:
Flow 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. Flow control valves are installed in the water supply pipeline. It is widely used in the system whose water is supplied by the water pump, such as the industrial water supply and tall building, regulate flow.
