style="text-indent:25px">減溫減壓裝置是用來調(diào)節(jié)蒸汽壓力、溫度的重要裝置，在火力發(fā)電廠中鍋爐產(chǎn)生過熱蒸汽，如果鍋爐不裝備減溫器，就無法將鍋爐出口蒸汽溫度控制在需要范圍內(nèi)，會使鍋爐汽輪機(jī)等設(shè)備因超溫?fù)p壞或造成重大事故。同時(shí)，在化工、輕工、醫(yī)藥、食品加工等一切使用蒸汽的生產(chǎn)工藝流程中，過熱蒸汽作為機(jī)械能量的產(chǎn)生提供了較佳的能源。而許多情況下，飽和蒸汽是更適合使用的，由于工藝及設(shè)備的原因，對壓力、溫度的控制也是必不可少的，通過減溫減壓裝置可以得到合適的動力蒸汽。</p><p

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(jìn)行整定壓力校驗(yàn)。當(dāng)壓力升高到管道內(nèi)額定壓力的50%時(shí)，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(dāng)蒸汽壓力達(dá)到規(guī)定的安全閥整定壓力時(shí)，固定并鎖緊重錘。此時(shí)，沖量安全閥應(yīng)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(shè)彈簧安全閥，須對彈簧安全閥作整定壓力、回座壓力試驗(yàn)，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(dá)到要求后，再對安全閥加以鉛封。上海減溫裝置多少錢</p></p><br
