【簡單介紹】
【詳細說明】
京蝶閥門從事閥門行業(yè)已有20年的歷史，一直以創(chuàng)新技術(shù)為宗旨，公司主打產(chǎn)品有蝶閥、閘閥、止回閥、過濾器等
該閥是通過電磁閥的導控實現(xiàn)準確的開啟或關閉，用于泵的出口處，防止介質(zhì)倒流的逆止控制閥，當泵即將停止供水前，閥門先行緩閉 90％ 左右，防止突然停泵而產(chǎn)生的水錘和水擊聲，當泵*停止后，閥門再*關閉，防止泵出現(xiàn)水的回流，有效地保護水泵，免受回流的沖擊而產(chǎn)生反轉(zhuǎn)，該閥有效防止水錘和水擊聲，密封可靠、動作平穩(wěn)、使用壽命長。電磁閥可采用交流電220V或直流電24V。 Used at the pump outlet to carry out an accurate open or close via the pilot control of the solenoid valve and。as a check control valve，to prevent the medium from back-flow．When the pump is about to stop water supply，it is slowly closed by about 90％ first to prevent both water hammer and water shock noise from being produced due to sudden stop of the pump and．when the pump stops compley．it is fully closed t0 prevent the water from back flow with the pump so as to effectively protect it from counter movement due to the shock of the back-flow This valve can effectively prevent water hammer and wa-ter shock noise．be reliably sealed and long time used and stably move The solenoid valve can use either AC220V or DC24V power.
四、主要外形及連接尺寸 Schematic diagram of installation
注：安裝示意圖中彈性座封閘閥或蝶閥任選，建議≥ DN350選蝶閥。 Note ： Either elastic seat ring sealed gate valve or butterfly valve can be selected in the schematic diagram of installation Recomended to select the butterfly valve in case of ≥ DN350 訂貨須知：（國家標準）
