and purpose
該閥是通過(guò)電磁閥的導(dǎo)控實(shí)現(xiàn)準(zhǔn)確的開(kāi)啟或關(guān)閉，用于泵的出口處，防止介質(zhì)倒流的逆止控制閥，當(dāng)泵即將停止供水前，閥門(mén)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(dāng)泵完全停止后，閥門(mén)再完全關(guān)閉，防止泵出現(xiàn)水的回流，有效地保護(hù)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(dòng)作平穩(wěn)、使用壽命長(zhǎng)。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. |
