style="text-indent:25px">幾種常用管道閥門的安裝：1.止回閥止回閥又稱逆止閥、單向閥，是一種在閥門前后壓力差作用下自動(dòng)啟閉的閥門，其作用是使介質(zhì)只做一個(gè)方向的流動(dòng)，而阻止介質(zhì)逆向往回流動(dòng)。止回閥按其結(jié)構(gòu)不同，有升降式、旋啟式和蝶形對(duì)夾式。升降式止回閥又有臥式與立式之分。安裝止回閥時(shí)，也應(yīng)注意介質(zhì)的流向，不能裝反。 2.減壓閥減壓閥是通過(guò)調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過(guò)改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。應(yīng)對(duì)閥門的密封性能進(jìn)行試驗(yàn)，確保其性能。宜興閥門電裝報(bào)價(jià)</p><p

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)，注意閥門在開關(guān)位的問(wèn)題。球閥維護(hù)保養(yǎng)時(shí)一般都處于開位狀態(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、開關(guān)位都正常。但為確保閥門注脂效果，有時(shí)需開啟或關(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。廣州礦用隔爆型閥門生產(chǎn)廠家</p></p><br
