在流體管道系統(tǒng)中閥門是控制元件，其主要作用是隔離設(shè)備和管道系統(tǒng)、調(diào)節(jié)流量、防止回流、調(diào)節(jié)和排泄壓力。由于管道系統(tǒng)選擇**適合的閥門顯得非常重要，所以，了解閥門的特性及選擇閥門的步驟和依據(jù)也變得至關(guān)重要起來。閥門承壓件材質(zhì)鑄銅、鑄鐵、球墨鑄鐵、高硅鑄鐵、鑄鋼、鍛鋼、高（低）合金鋼、不銹耐酸鋼、哈氏合金、因科鎳爾、蒙乃爾合金、雙相不銹鋼、鈦合金等。并且能夠生產(chǎn)各種電動(dòng)、氣動(dòng)、液動(dòng)閥門驅(qū)動(dòng)裝置。面對(duì)如此眾多的閥門品種和復(fù)雜的各種工況，要選擇管道系統(tǒng)**適合安裝的閥門產(chǎn)品，首先應(yīng)了解閥門的特性；其次應(yīng)掌握選擇閥門的步驟和依據(jù)；再者應(yīng)遵循選擇閥門的原則。閥門的特性一般有兩種，使用特性和結(jié)構(gòu)特性。1、使用特性：它確定了閥門的主要使用性能和使用范圍，屬于閥門使用特性的有：閥門的類別(閉路閥門、調(diào)節(jié)閥門、安全閥門等)；產(chǎn)品類型(閘閥、截止閥、蝶閥、球閥等)；閥門主要零件(閥體、閥蓋、閥桿、閥瓣、密封面)的材料；閥門傳動(dòng)方式等。2、結(jié)構(gòu)特性：它確定了閥門的安裝、維修、保養(yǎng)等方法的一些結(jié)構(gòu)特性，屬于結(jié)構(gòu)特性的有：閥門的結(jié)構(gòu)長度和總體高度、與管道的連接形式(法蘭連接、螺紋連接、夾箍連接、外螺紋連接、焊接端連接等)。</p><p> 確保閥門的直角行程。第八、注脂后，一定封好注脂口。避免雜質(zhì)進(jìn)入，或注脂口處脂類氧化。封蓋要涂抹防銹脂，避免生銹。以便下一次操作時(shí)應(yīng)用。第九、注脂時(shí)，也要考慮在今后油品順序輸送中具體問題具體對(duì)待。鑒于柴油與汽油不同的品質(zhì)，應(yīng)考慮汽油的沖刷和分解能力。在以后閥門操作，遇到汽油段作業(yè)時(shí)，及時(shí)補(bǔ)充潤滑脂，防止磨損情況發(fā)生。第十、注脂時(shí)，不要忽略閥桿部位的注脂。閥軸部位有滑動(dòng)軸套或填料，也需要保持潤滑狀態(tài)，以減小操作時(shí)的摩擦阻力，如不能確保潤滑，則電動(dòng)操作時(shí)扭矩加大磨損部件，手動(dòng)操作時(shí)開關(guān)費(fèi)力。第十一、有些球閥閥體上標(biāo)有箭頭，如果沒有附帶英文FIOW字跡，則為密封座作用方向，不作為介質(zhì)流向參考，閥門自泄方向相反。通常情況下，雙座密封的球閥具有雙向流向。第十二、閥門維護(hù)時(shí)，也要注意電動(dòng)頭及其傳動(dòng)機(jī)構(gòu)中進(jìn)水問題。尤其在雨季滲入的雨水。一是使傳動(dòng)機(jī)構(gòu)或傳動(dòng)軸套生銹，二是冬季凍結(jié)。造成電動(dòng)閥操作時(shí)扭矩過大，損壞傳動(dòng)部件會(huì)使電機(jī)空載或超扭矩保護(hù)跳開無法實(shí)現(xiàn)電動(dòng)操作。傳動(dòng)部件損壞，手動(dòng)操作也無法進(jìn)行。在超扭矩保護(hù)動(dòng)作后，手動(dòng)操作也同樣無法開關(guān)，如強(qiáng)行操作，將損壞內(nèi)部合金部件。阿勒泰耐腐蝕閥門價(jià)格；</p><div
