SJ700水泵控製閥
 

一、結構及用途 Structure and purpose

該閥是通過電磁閥的導控實現準確的開啟或關閉,用於泵的出口處,防止介質倒流的逆止控製閥,當泵即將停止供水前,閥門先行緩閉 90% 左右,防止突然停泵而產生的水錘和水擊聲,當泵完全停止後,閥門再完全關閉,防止泵出現水的回流,有效地保護水泵,免受回流的衝擊而產生反轉,該閥有效防止水錘和水擊聲,密封可靠、動作平穩、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 completely.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.

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
