style="text-indent:25px">閥門注脂時(shí)的維護(hù)保養(yǎng)工作：1、閥門注脂時(shí)，注意閥門在開(kāi)關(guān)位的問(wèn)題。球閥維護(hù)保養(yǎng)時(shí)一般都處于開(kāi)位狀態(tài)，特殊情況下選擇關(guān)閉保養(yǎng)。其他閥門也不能一概以開(kāi)位論處。閘閥在養(yǎng)護(hù)時(shí)則必須處于關(guān)閉狀態(tài)，確保潤(rùn)滑脂沿密封圈充滿密封槽溝，如果開(kāi)位，密封脂則直接掉入流道或閥腔，造成浪費(fèi)。2、閥門注脂時(shí)，常忽略注脂效果問(wèn)題。注脂操作中壓力、注脂量、開(kāi)關(guān)位都正常。但為確保閥門注脂效果，有時(shí)需開(kāi)啟或關(guān)閉閥門，對(duì)潤(rùn)滑效果進(jìn)行檢查，確認(rèn)閥門閥球或閘板表面潤(rùn)滑均勻。3、注脂時(shí)，要注意閥體排污和絲堵泄壓?jiǎn)栴}。閥門打壓試驗(yàn)后，密封腔閥腔內(nèi)氣體和水分因環(huán)境溫度升高而升壓，注脂時(shí)要先進(jìn)行排污泄壓，以利于注脂工作的順利進(jìn)行。注脂后密封腔內(nèi)的空氣和水分被充分置換出來(lái)。及時(shí)泄掉閥腔壓力，也保障了閥門使用安全。注脂結(jié)束后，一定要擰緊排污和泄壓絲堵，以防意外發(fā)生。南昌閥門電裝訂購(gòu)檢查閥門墊料、填料及緊固件(螺栓)是否適合于工作介質(zhì)性質(zhì)的要求。</p><div

style="text-indent:25px">閥門：按結(jié)構(gòu)種類分主要有：旋塞閥、閘閥、截止閥、球閥—用于開(kāi)啟或關(guān)閉管道的介質(zhì)流動(dòng)。止回閥(包括底閥)—用于自動(dòng)防止管道內(nèi)的介質(zhì)倒流。節(jié)流閥—用于調(diào)節(jié)管道介質(zhì)的流量。蝶閥—用于開(kāi)啟或關(guān)閉管道內(nèi)的介質(zhì)。也可作調(diào)節(jié)用。安全閥—用于鍋爐、容器設(shè)備及管道上，當(dāng)介質(zhì)壓力趔過(guò)規(guī)定數(shù)值時(shí)，能自動(dòng)排除過(guò)剩介質(zhì)壓力，保證生產(chǎn)運(yùn)行安全。減壓閥—用于自動(dòng)降低管道及設(shè)備內(nèi)介質(zhì)壓力。系使介質(zhì)經(jīng)過(guò)閥瓣的間隙時(shí)，產(chǎn)生阻力造成壓力損失，達(dá)到減壓目的。疏水器—用于蒸汽管道上自動(dòng)排除冷凝水，防止蒸汽損失或泄漏。按用途，根據(jù)閥門的不同用途可分：1. 開(kāi)斷用：用來(lái)接通或切斷管路介質(zhì)，如截止閥、閘閥、球閥、蝶閥等。2. 止回用：用來(lái)防止介質(zhì)倒流，如止回閥。3. 調(diào)節(jié)用：用來(lái)調(diào)節(jié)介質(zhì)的壓力和流量，如調(diào)節(jié)閥、減壓閥。4. 分配用：用來(lái)改變介質(zhì)流向、分配介質(zhì)，如三通旋塞、分配閥、滑閥等。5. 安全閥：在介質(zhì)壓力超過(guò)規(guī)定值時(shí)，用來(lái)排放多余的介質(zhì)，保證管路系統(tǒng)及設(shè)備安全，如安全閥、事故閥。6. 他特殊用途：如疏水閥、放空閥、排污閥等。</p><p
