700X水泵控制閥產(chǎn)品簡(jiǎn)介
700X水泵控制閥,是一種安裝在水泵出口處,防止介質(zhì)倒流的逆止類(lèi)閥門(mén)。當(dāng)水泵即將停止供水前,閥門(mén)先行緩慢關(guān)閉90%左右,防止突然停泵而產(chǎn)生的水錘和水擊聲,當(dāng)水泵完全停止后,閥門(mén)在完全關(guān)閉,防止泵出的水回流,有效地保護(hù)水泵,免受回流的沖擊而產(chǎn)生反轉(zhuǎn)。該產(chǎn)品是水泵出口必不可少的保護(hù)裝置。閥門(mén)呈流線型設(shè)計(jì),通過(guò)電磁閥的導(dǎo)控實(shí)現(xiàn)準(zhǔn)確的啟閉,使用安全可靠,有效地防止水錘和水擊聲,使用壽命長(zhǎng),安裝,維修方便。
700X水泵控制閥工作原理
當(dāng)水泵工作閥門(mén)向下游供水時(shí),電磁導(dǎo)閥全開(kāi),針閥調(diào)到適當(dāng)開(kāi)度,上游水經(jīng)過(guò)針閥,導(dǎo)閥,單向閥進(jìn)入主閥控制室,經(jīng)電磁導(dǎo)閥流出,此時(shí)主閥控制室壓力保持主閥處于合適開(kāi)度,保持下游正常供水。
當(dāng)水泵停止工作時(shí),電磁導(dǎo)閥先關(guān)閉,主閥停止排水,主閥室壓力升高,主閥開(kāi)始關(guān)閉,當(dāng)關(guān)閉90%時(shí),主閥上部行程開(kāi)關(guān)輸出停泵信號(hào),水泵停止運(yùn)轉(zhuǎn),此時(shí),主閥下游水經(jīng)過(guò)單向閥進(jìn)入主控制室,控制室壓力升高,主閥關(guān)閉。
