style="text-indent:25px">減溫減壓裝置均由活門頂桿、調(diào)壓彈簧、彈性薄膜裝置、減壓門等零部件組成。減壓系統(tǒng)主要用于將高壓氣體自動(dòng)降為中壓氣體，降至壓力為2MPa，然后送入第二級(jí)減壓系統(tǒng)。在二級(jí)減壓系統(tǒng)，當(dāng)旋擰調(diào)壓螺釘時(shí)，通過(guò)調(diào)壓彈簧、彈性薄膜裝及活門頂桿，使減壓活門作不同程度的開(kāi)啟和關(guān)閉，以用來(lái)調(diào)節(jié)減壓系統(tǒng)送入的氧氣的減壓程度或停止供氣。壓力高的空氣經(jīng)過(guò)節(jié)流閥的節(jié)流在低壓氣室進(jìn)行膨脹，使高壓空氣變成壓力相對(duì)較低的空氣，調(diào)節(jié)節(jié)流閥的開(kāi)度，對(duì)高壓空氣的節(jié)流程度不同，高壓空氣的膨脹效果也不一樣，減壓后的空氣壓力也就不一樣。流入低壓室的高壓氣體量增多，使低氣壓室氣體壓力增高；當(dāng)氣體用量減小時(shí)，減壓話門開(kāi)啟度逐漸縮小，使低氣壓室內(nèi)氣體不會(huì)增高。減溫裝置工廠</p></p><br
