500X泄壓/持壓閥

500X泄壓/持壓閥

結(jié)構(gòu)特點(diǎn)和用途

    由主閥、泄壓/持壓導(dǎo)閥針閥、球閥、微形過(guò)濾器和壓力表組成水力控制接管系統(tǒng)。利用水力自動(dòng)操作,即可以作泄壓閥用又可作持壓閥用。作泄壓閥用時(shí),可維持供水路壓力在設(shè)定的安全值之下;做持壓閥用,可維持主閥上游水壓在設(shè)定值之上,保持主閥上游供水壓力。
    本產(chǎn)品利用水力自力控制,不需要其它裝置和能源,保養(yǎng)簡(jiǎn)便,一閥多用。
    本系列閥門產(chǎn)品廣泛用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。

工作原理

   1、作泄壓閥:當(dāng)泄壓/持壓導(dǎo)閥調(diào)整為泄壓狀態(tài)時(shí),水通過(guò)針閥、主閥控制室、球閥A、泄壓/持壓導(dǎo)閥、球閥B流向出口,此時(shí)主閥處于開(kāi)啟狀態(tài)。當(dāng)進(jìn)口壓力超過(guò)泄壓/持壓導(dǎo)閥設(shè)定的安全值時(shí),泄壓導(dǎo)閥會(huì)自動(dòng)開(kāi)啟,通過(guò)球閥C放出部分水,使管路泄壓。當(dāng)壓力恢復(fù)到安全值時(shí),泄壓閥自動(dòng)關(guān)閉。作泄壓閥時(shí),各球閥常開(kāi)。
    2、作持壓閥:當(dāng)泄壓/持壓導(dǎo)閥調(diào)整為持壓狀態(tài)時(shí),只要主閥進(jìn)口水壓低于導(dǎo)閥設(shè)定值,導(dǎo)閥即關(guān)閉。主要控制室升壓,主閥關(guān)閉。當(dāng)主閥上游供水壓力超過(guò)導(dǎo)閥設(shè)定壓力時(shí),持壓導(dǎo)閥才能打開(kāi),控制室的水經(jīng)球閥排至出口,控制室降壓主閥開(kāi)啟,開(kāi)始供水,即保持了上游水壓。作持壓閥用時(shí),球閥C常閉或用絲堵?lián)Q下。
