style="font-size:16px;">閘閥定義是在管路中用途比較廣的一種閥門，主要起到接通和截斷介質(zhì)的作用。不適用于調(diào)節(jié)介質(zhì)的流量，但能根據(jù)閥桿升降的高低來判斷流量大小(如消防用彈性座封閘閥配有啟閉刻度)。閘閥相比較其它閥門，對壓力、溫度、口徑等要求的適用范圍要廣。二.閘閥結(jié)構(gòu)閘閥根據(jù)內(nèi)部結(jié)構(gòu)的不同可分為：楔式單閘板式、彈性閘板式、雙閘板式、平行閘板式。根據(jù)閥桿支架的不同又可分為：明桿閘閥和暗桿閘閥。閘閥閥體的結(jié)構(gòu)決定與閥體與管道、閥體與閥蓋的連接、就制造方法而言，有鑄造、鍛造、鍛焊、鑄焊以及管板焊接等幾種。鍛造閥體已向大口徑方向發(fā)展，而鑄造閥體逐漸向小口徑發(fā)展。任何一種閘閥閥體即可鍛造，也可鑄造，應(yīng)根據(jù)用戶要求以及制造廠擁有的制造手段而定。</span>

style="font-size:16px;">閘閥是閥門類型的主要關(guān)鍵之一，閥門型號由閥門類型、驅(qū)動方式、連接形式、結(jié)構(gòu)形式、密封面材料或襯里材料類型、壓力代號或工作溫度下的工作壓力、閥體材料七部分組成。安裝方法閘閥的安裝方法及注意需求安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著；各連接部位螺栓，要求均勻擰緊；檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活；用戶在安裝閥門前，必須校對閥門型號，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性；用戶在安裝閥門時，必須預(yù)留閥門驅(qū)動的必要空間；驅(qū)動裝置的接線須按線路圖進(jìn)行；閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。閘閥是否適合工業(yè)上的安裝就要在選購的時候注意。蘭州閥門廠家給您專業(yè)的建議。</span> </p><p> <span style="font-size:16px;">閘閥因為只能全開和全關(guān)，它在完全打開時，閥體通道內(nèi)的介質(zhì)流動阻力幾乎為0，所以閘閥的啟閉會非常省力，但閘板距離密封面距離遠(yuǎn)，啟閉時間長。閘閥流向兩個方向效果都一樣，安裝沒有進(jìn)出口方向的要求，介質(zhì)可以雙向流通。截止閥則需要嚴(yán)格按照閥體箭頭標(biāo)識的方向進(jìn)行安裝，關(guān)于截止閥進(jìn)出口方向還有個明文規(guī)定，我國閥門“三化給”規(guī)定截止閥的流向一律采用自上而下。截止閥是低進(jìn)高出，從外觀看有明顯的管道不在一相水平線上。閘閥流道在一個水平線上。閘閥的行程比截止閥的要大。閘閥也叫閘板閥,是使用的閥門。它的閉合原理是閘板密封面與閥座密封面高度光潔、平整一致,相互貼合,可阻止介質(zhì)流過,并依靠頂模、彈簧或閘板的模形,來增強(qiáng)密封效果。它在管路中主要起切斷作用。</span>
