在流體管道系統(tǒng)中閥門(mén)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(mén)顯得非常重要，所以，了解閥門(mén)的特性及選擇閥門(mén)的步驟和依據(jù)也變得至關(guān)重要起來(lái)。閥門(mén)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(mén)驅(qū)動(dòng)裝置。面對(duì)如此眾多的閥門(mén)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(mén)產(chǎn)品，首先應(yīng)了解閥門(mén)的特性；其次應(yīng)掌握選擇閥門(mén)的步驟和依據(jù)；再者應(yīng)遵循選擇閥門(mén)的原則。閥門(mén)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(mén)的主要使用性能和使用范圍，屬于閥門(mén)使用特性的有：閥門(mén)的類別(閉路閥門(mén)、調(diào)節(jié)閥門(mén)、安全閥門(mén)等)；產(chǎn)品類型(閘閥、截止閥、蝶閥、球閥等)；閥門(mén)主要零件(閥體、閥蓋、閥桿、閥瓣、密封面)的材料；閥門(mén)傳動(dòng)方式等。2、結(jié)構(gòu)特性：它確定了閥門(mén)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(mén)的結(jié)構(gòu)長(zhǎng)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><div
