應(yīng)根據(jù)其它要求，需要球閥、旋塞閥、蝶閥、快開閘閥等。閘閥和截止閥是閥門中使用量**大的兩類閥門。選用時，應(yīng)綜合考慮。閘閥流阻小，輸送介質(zhì)的能耗少，但維修困難；截止閥結(jié)簡單，維修方便，但流阻較大。從維修角度分析，截止閥的維修要比閘閥方便；水和蒸汽在截止閥中，壓力降不大，因而截止閥在水、汽之類介質(zhì)管道上得到普遍的使用。但在石油產(chǎn)品等粘度較大的介質(zhì)中，雖然閘閥維修困難，仍然被大量采用。在焊接連接的管道中，應(yīng)盡量選用焊接連接的截止閥，不宜選用焊接連接的閘閥。因為在管道上修理閘閥的密封面比修理截止閥的密封面困難得多，而且閘閥在溫度變化大的情況下閘板與閥座容易卡死。七、驅(qū)動閥門的選用返回頁首作為管線閉路裝置的閘閥、截止閥、球閥、蝶閥、旋塞閥、節(jié)流閥、隔膜閥等閥門被***使用，其中閘閥、截止閥用量**大。***章第六節(jié)中較系統(tǒng)敘述了閥門的名詞術(shù)語、結(jié)構(gòu)形式、適用范圍等，可作為閥門類別、型號的選定依據(jù)。當(dāng)閥門的類別、型號確定之后，隨之確定閥門的殼體材料、密封面材料、適用溫度、適用介質(zhì)、公稱通徑等。因情況下可按下列步驟進(jìn)行。1.閥門選用步驟⑴根據(jù)介質(zhì)特性、工作壓力和溫度。新疆三通閥門廠家鑄鋼球閥報價鑄鋼球閥公司。</p><div

也可用作放水閥和放氣閥。常見的關(guān)斷閥有閘閥、截止閥、球閥和蝶閥等。閘閥可分為明桿和暗桿、單閘板與雙閘板、楔形閘板與平行閘板等。閘閥關(guān)閉嚴(yán)密性不好，大直徑閘閥開啟困難；沿水流方向閥體尺寸小，流動阻力小，閘閥公稱直徑跨度大。截止閥按介質(zhì)流向分直通式、直角式和直流式三種，有明桿和暗桿之分。截止閥的關(guān)閉嚴(yán)密性較閘閥好，閥體長，流動阻力**公稱直徑為DN200。球閥的閥芯為開孔的圓球。板動閥桿使球體開孔正對管道軸線時為全開，轉(zhuǎn)90°為全閉。球閥有一定的調(diào)節(jié)性能，關(guān)閉較嚴(yán)密。蝶閥的閥芯為圓形閥板，它可沿垂直管道軸線的立軸轉(zhuǎn)動。當(dāng)閥板平面與管子軸線一致時，為全開；閘板平面與管子軸線垂直時，為全閉。蝶閥閥體長度小，流動阻力小，比閘閥和截止閥價格高。[1]（二）止回閥這類閥門用于防止介質(zhì)倒流，利用流體自身的動能自行開啟，反向流動時自動關(guān)閉。常設(shè)于水泵的出口、疏水器出口以及其他不允許流體反向流動的地方。止回閥分旋啟式、升降式和對夾式三種。對于旋啟式止回閥，流體只能從左向右流動時，反向流動時自動關(guān)閉。對于升降式止回閥，流體從左向右流動時，閥芯抬起，形成通路，反向流動時閥芯被壓緊到閥座上而被關(guān)閉。對于對夾式止回閥。阿圖什立臥兩用止回閥廠家。</p><div
