style="text-indent:25px">真空閥門是鑄造體的時(shí)候，有可能會(huì)存在有質(zhì)量不高，閥體和閥蓋體上出現(xiàn)砂眼、松散組織、夾渣等缺陷。使用過程中閥門被重物撞擊后損壞閥體和閥蓋泄漏；閥門焊接不良，存在著夾渣、未焊接，應(yīng)力裂紋等缺陷；這幾種都會(huì)造成閥體和閥蓋泄漏。如按以上幾種現(xiàn)象我們應(yīng)該提高真空閥門的鑄造質(zhì)量，安裝前嚴(yán)格按規(guī)定進(jìn)行強(qiáng)度試驗(yàn)；對氣溫在0°和0°以下的真空閥門，應(yīng)進(jìn)行保溫或拌熱，停止使用的閥門應(yīng)排除積水；由焊接組成的真空閥閥體和閥蓋的焊縫，應(yīng)按有關(guān)焊接操作規(guī)程進(jìn)行，焊后還應(yīng)進(jìn)行探傷和強(qiáng)度試驗(yàn)；閥門上禁止推放重物，不允許用手錘撞擊鑄鐵和非金屬閥門，大口徑閥門的安裝應(yīng)有支架。</p><p style="text-indent:25px">真空閥門的防堵塞的方法。清洗法，管路中的焊渣、鐵銹、渣子等在節(jié)省口、導(dǎo)向部位、下閥蓋平衡孔內(nèi)形成阻塞或卡住使閥芯曲面、導(dǎo)向面發(fā)生拉傷和劃痕、密封面上發(fā)生壓痕等。這常常發(fā)生于新投運(yùn)體系和大修后投運(yùn)初期。這是常見的毛病。外接沖刷法，對一些易沉積、含有固體顆粒的介質(zhì)選用普通閥調(diào)節(jié)時(shí)，常常在節(jié)省口、導(dǎo)向處阻塞，可鄙人閥蓋底塞處外接沖刷氣體和蒸汽。當(dāng)閥發(fā)生阻塞或卡住時(shí)，翻開外接的氣體或蒸氣閥門，即可在不動(dòng)調(diào)節(jié)閥的狀況下完成沖洗作業(yè)，使閥正常運(yùn)行。安裝管道過濾器法，對小口徑的調(diào)節(jié)閥，尤其是超小流量調(diào)節(jié)閥，其節(jié)省空隙特小，介質(zhì)中不能有一點(diǎn)點(diǎn)渣物。遇此狀況阻塞，在閥前管道上安裝一個(gè)過濾器，以保證介質(zhì)順暢通過。帶定位器運(yùn)用的調(diào)節(jié)閥，定位器作業(yè)不正常，其氣路節(jié)省口阻塞是常見的毛病。因而，帶定位器作業(yè)時(shí)，處理好氣源，一般選用的辦法是在定位器前氣源管線上安裝空氣過濾減壓閥。材料的放氣是真空閥門總漏量中的一個(gè)重要組成部分。</p><div
