500X泄壓閥用途 500X泄壓/持壓閥由主閥、泄壓/持壓導閥針閥、球閥、微形過濾器和壓力表組成水力控制接管系統(tǒng)。利用水力自動操作,即可以作泄壓閥用又可作持壓閥用。作泄壓閥用時,可維持供水路壓力在設定的安全值之下;做持壓閥用,可維持主閥上游水壓在設定值之上,保持主閥上游供水壓力。
500X泄壓閥工作原理 1、作泄壓閥:當泄壓/持壓導閥調(diào)整為泄壓狀態(tài)時,水通過針閥、主閥控制室、球閥A、泄壓/持壓導閥、球閥B流向出口,此時主閥處于開啟狀態(tài)。當進口壓力超過泄壓/持壓導閥設定的安全值時,泄壓導閥會自動開啟,通過球閥C放出部分水,使管路泄壓。當壓力恢復到安全值時,泄壓閥自動關(guān)閉。作泄壓閥時,各球閥常開。
