500X-10C,500X-25C,500X-40C,500X-10P,500X-25P,500X-40P,泄壓閥持壓閥
500X泄壓持壓閥產(chǎn)品簡介
500X泄壓閥、持壓閥主要用于消防或其它供水系統(tǒng)中，以防止系統(tǒng)超壓和維持消防供水系統(tǒng)的壓力。消防泵關(guān)閉后還可以減少水錘的沖擊。也用于大型供水系統(tǒng)的水錘消除裝置，當給水管路中超過泄壓閥設(shè)定壓力時，泄壓閥及時泄壓，保護管線安全。也可做持壓閥用，保障主閥上游的供水壓力。
本產(chǎn)品利用水力自動控制，不需其他裝置和能量，保養(yǎng)簡單，一閥多用。
本產(chǎn)品廣泛用于高層建筑，生活等供水管網(wǎng)以及城市供水管網(wǎng)系統(tǒng)。
500X泄壓持壓閥產(chǎn)品工作原理
做泄壓閥用，當導(dǎo)閥調(diào)整泄壓閥狀態(tài)時，水通過針閥，主閥控制室，球閥A，泄壓/持壓導(dǎo)閥，球閥B流向出口，此時，主閥處于開啟狀態(tài)，當進口壓力超過導(dǎo)閥設(shè)定的安全值時，泄壓閥會自動開啟，通過球閥C放出部分水，使管路泄壓。當管路恢復(fù)到安全值時，泄壓閥自動關(guān)閉，做泄壓閥時，各球閥常開。
做持壓閥，當導(dǎo)閥調(diào)整為持壓閥狀態(tài)時，只要主閥進口水壓力低于導(dǎo)閥設(shè)定壓力值時，導(dǎo)閥即關(guān)閉，主閥控制室壓力升高，主閥關(guān)閉。當主閥上游壓力超過主閥設(shè)定壓力時，主閥才能打開，控制室的水經(jīng)球閥排至出口，控制室降壓，主閥開啟，開始供水，即保護上游水壓，做持壓閥時，球閥常閉或用絲堵?lián)Q下。
