style="text-indent:25px">減溫減壓裝置升壓過程中，對沖量式安全閥必須進行整定壓力校驗。當壓力升高到管道內(nèi)額定壓力的50%時，將沖量式安全閥的杠桿向上抬起，檢查主安全閥開啟和關(guān)閉動作是否靈敏，當蒸汽壓力達到規(guī)定的安全閥整定壓力時，固定并鎖緊重錘。此時，沖量安全閥應再動作一次，檢查其整定壓力是否正常，主安全閥動作是否靈敏，有無卡阻現(xiàn)象。然后對重錘和杠桿加以鉛封或加鎖。若蒸汽管道上裝設彈簧安全閥，須對彈簧安全閥作整定壓力、回座壓力試驗，檢查其整定壓力是否正常，動作是否靈敏，有無卡阻現(xiàn)象。達到要求后，再對安全閥加以鉛封。減溫減壓閥即是通過控制閥內(nèi)的介質(zhì)流量，將介質(zhì)的壓力減低的。松江區(qū)減溫減壓裝置要多少錢</p><p
