style="text-indent:25px">真空閥門(mén)如何維護(hù)?1、明確目的.對(duì)壓力維護(hù)的目的，在于延長(zhǎng)閥門(mén)壽命和保證正常運(yùn)行。2、對(duì)于經(jīng)常與閥桿螺母摩擦的閥桿螺紋，可以涂一點(diǎn)黃干油、二硫化鉬或石墨粉，目的是潤(rùn)滑減少摩擦阻力。3、流水不腐，戶樞不蠹。不僅經(jīng)常轉(zhuǎn)動(dòng)的自力式壓力調(diào)節(jié)閥要有潤(rùn)滑措施。對(duì)于不經(jīng)常啟閉的自力式壓力調(diào)節(jié)閥，也要定期轉(zhuǎn)動(dòng)手輪，對(duì)閥桿螺紋添加潤(rùn)滑劑，以防生銹。4、真空閥門(mén)，要對(duì)閥桿加保護(hù)套，目的是防止雨、雪、塵土等進(jìn)入真空閥門(mén)內(nèi)部導(dǎo)致銹污。真空閥門(mén)大致有兩種:一種是關(guān)閉后隔絕大氣和真空空間的開(kāi)關(guān)形閥門(mén),另一種是調(diào)整通氣量的流量可變閥門(mén)。</p><div
