style="font-size:16px;">閘閥和蝶閥在管道使用中都是起開關，調節(jié)流量的作用。當然在蝶閥和閘閥的選配過程中還是有方法的。在供水管網(wǎng)中為了降低管道覆土深度，一般口徑較大管道選配蝶閥，對覆土深度影響不大的，力求選配閘閥，但是同樣規(guī)格的閘閥價格又比蝶閥的價格高。至于口徑的分界線應各地按具體情況考慮。從近十年使用情況而言，蝶閥出現(xiàn)的故障比閘閥高，因此在條件許可的情況下，擴大閘閥的使用范圍是值得關注的。關于閘閥近年來，國內不少閥門制造廠家，研制、仿制軟密封閘閥，這種閘閥比傳統(tǒng)的楔式或平行雙閘板式閘閥有如下特點：軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機械加工，不使用密封銅環(huán)，節(jié)約有色金屬。軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機械加工，不使用密封銅環(huán)，節(jié)約有色金屬。軟密封閘閥底部無凹坑，不積存渣物，閘閥啟閉的故障率低。軟密封襯膠閥板尺寸統(tǒng)一，互換性強。</span>

style="font-size:16px;">一般用于控制流體的啟閉，流體阻力小，密封性能好，介質的流向不受限制，開閉所需外力較小，結構長度較短。閥桿有明桿和暗桿之分，明桿式閘閥適用于腐蝕介質，在化工工程上基本使用明桿式閘閥。暗桿閘閥主要用于水道上，多用于低壓、無腐蝕性介質的場合，如一些鑄鐵和銅閥門。閘板的結構形式包括楔式閘板、平行式閘板。楔式閘板有單閘板，雙閘板之分。平行式閘板多用于油氣輸送系統(tǒng)，在化工裝置中不常用。閘閥是指關閉件（閘板）沿通道軸線的垂直方向移動的閥門，在管路上主要作為切斷介質用，即全開或全關使用。一般，閘閥不可作為調節(jié)流量使用。它可以適用低溫壓也可以適用于高溫高壓，并可根據(jù)閥門的不同材質。但閘閥一般不用于輸送泥漿等介質的管路中。</span> </p><p> <span style="font-size:16px;">彈性閘板閘閥它是楔式單閘板閥的特殊形式。與楔式閘閥比較，在高溫時，密封性能好，閘板受熱后不易被卡??；適用于蒸汽、高溫油品及油氣介質，并適用于開關頻繁的部位；不適用于易結焦的介質。雙閘板閘閥密封性能較楔式閘閥好，當密封面的傾斜角度和閥座配合不十分準確時，仍具有較好的密封性能；閘閥閥體的流道可分為，全通徑式和縮徑式兩種。流道孔徑與閥門公稱通經(jīng)，基本相同的為全通徑式；流通孔徑比閥門公稱通經(jīng)小的稱為縮徑式。閘板密封面磨損后，將球面頂心底部的金屬墊更換后即可使用，一般不必堆焊和研磨密封面；適用于蒸汽、高溫油品及油氣介質，并適用于開關頻繁的部位；不適用于易結焦的介質。平行式閘閥密封性能較其它形式的閘閥要差；適用于溫度和壓力較低的介質；閘板及閥座的密封面的加工及檢修比其他形式的閘閥簡單。</span>

style="font-size:16px;">閘閥的特點和用途：閘閥的優(yōu)點是流動阻力小，開閉較省力，不受介質流向的限制，介質可以兩個方向流動，結構尺寸較小，全開時密封面受介質沖蝕小。缺點是結構復雜，高度尺寸較大，開啟需一定的空間，開閉時間長，開閉時密封面容易受沖蝕和擦傷。閘閥的應用范圍是由其特點決定的，一般用于公稱通徑大于100mm的管道上，作切斷作用。閘閥可依靠介質壓力緊緊與密封面緊閉，從而達到不泄露的效果。當啟閉時閥芯和閥座密封面始終接觸并相互磨擦，因此密封面容易磨損，閘閥處于接近關閉時，管道前后壓差很大，使密封面磨損更加嚴重。閘閥的結構會比截止閥更復雜，從外形來看，同口徑情況下，閘閥要比截止閥高，截止閥要比閘閥長。另外，閘閥還有明桿和暗桿之分。截止閥沒有。</span>
