應(yīng)根據(jù)其它要求，需要球閥、旋塞閥、蝶閥、快開(kāi)閘閥等。閘閥和截止閥是閥門(mén)中使用量**大的兩類(lèi)閥門(mén)。選用時(shí)，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(jiǎn)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(lèi)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?yàn)樵诠艿郎闲蘩黹l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(dòng)閥門(mén)的選用返回頁(yè)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(mén)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(mén)的名詞術(shù)語(yǔ)、結(jié)構(gòu)形式、適用范圍等，可作為閥門(mén)類(lèi)別、型號(hào)的選定依據(jù)。當(dāng)閥門(mén)的類(lèi)別、型號(hào)確定之后，隨之確定閥門(mén)的殼體材料、密封面材料、適用溫度、適用介質(zhì)、公稱(chēng)通徑等。因情況下可按下列步驟進(jìn)行。1.閥門(mén)選用步驟⑴根據(jù)介質(zhì)特性、工作壓力和溫度。</p><p>
