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(zhì)的流向不受限制，開閉所需外力較小，結(jié)構(gòu)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(zhì)，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(zhì)的場合，如一些鑄鐵和銅閥門。閘板的結(jié)構(gòu)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(guān)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(zhì)用，即全開或全關(guān)使用。一般，閘閥不可作為調(diào)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(zhì)。但閘閥一般不用于輸送泥漿等介質(zhì)的管路中。</span>

</p><p> <span style="font-size:16px;">閘閥是具有雙流向的閥門，不受介質(zhì)流向限制，因此適用于介質(zhì)可能改變流動方向的管路，同時也便于安裝。外形設(shè)計尺寸高，起閉時間長。開啟時需要將閥板提升到閥腔上部，關(guān)閉時又需要將閥板全部落到閥座內(nèi)，因此閥板啟閉行程大，時間長；2.由于閘閥的閥板與閥座的兩密封面在啟閉過程中存在摩擦，因此密封面容易擦傷，對密封性能和使用壽命都有影響，并且不易維修。不同結(jié)構(gòu)閘閥的性能比較1.楔式單閘板閘閥a、結(jié)構(gòu)較彈性閘板閥簡單；b、在較高溫度下，密封性能不如彈性閘板閥或雙閘板閥好；c、適用于易結(jié)焦的高溫介質(zhì)。2.彈性閘板閘閥a、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??；b、適用于蒸汽、高溫油品及油氣介質(zhì)，并適用于開關(guān)頻繁的部位；c</span><span

style="font-size:16px;">軟密封閘閥將是供水行業(yè)樂意采用的一種形式。目前國內(nèi)制造的軟密封閘閥口徑達1500mm，但多數(shù)廠家制造的口徑在80-300mm間，國內(nèi)制造工藝上尚有諸多問題。軟密封閘閥的關(guān)鍵部件是襯膠閥板，而襯膠閥板的技術(shù)要求較高，國外也不是所有廠家都能達到的，往往是從質(zhì)量可靠的廠方購進組裝。軟密封閘閥的銅螺母塊是嵌掛在襯膠閥板上方的，類似閘閥的結(jié)構(gòu)，由于螺母塊的活動摩擦容易使閥板的襯膠剝離。國外某公司的軟密封閘閥，銅螺母塊是鑲嵌在襯膠閘板內(nèi)，形成整體，克服了上述缺點，但閥蓋與閥體組合的同心度要求較高。啟閉軟密封閘閥時，千萬不應(yīng)關(guān)閉過死，只要達到止水效果即可，否則不易開啟或襯膠剝離。某閥門廠家，在閥門試壓檢驗時，使用扭力板手來控制關(guān)閉的程度，作為自來水公司的閥門操作人</span><span style="font-size:16px;">員也應(yīng)效仿此種啟閉方法。</span> 使用在開關(guān)頻繁的部位，不宜用于易結(jié)焦的介質(zhì)；固原閘閥聯(lián)系人</p><p style="text-indent:25px">閘閥的閘板隨閥桿一起作直線運動的，亦叫明桿閘閥。固原閘閥聯(lián)系人</p><p> <span style="font-size:16px;">閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關(guān)，不適門參數(shù)而異,通常為5°,介質(zhì)溫度不高時為2°52‘。改善其工藝性,彌補密封面角度在加工過程中產(chǎn)生的偏差,這種閘板叫做彈性閘板。閘門介紹閘閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閥門關(guān)閉時，要依靠外力強行將閘板壓向閥座，以保證密封面的密封性。運動方式：閘閥的閘板隨閥桿一起作直線運動的，亦叫明桿閘閥。通常在升降桿上有梯形螺紋，通過閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運動變?yōu)橹本€運動,也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏?。開啟閥門時，當閘板提升高度等于閥門通徑的1：1倍時，流體的通道完全暢通，但在運行時，此位置是無法監(jiān)視的。實際使用時，是以閥桿的頂點作為標志，即開不動的位置，作為它的全開位置。為考慮溫度變化出現(xiàn)</span><span style="font-size:16px;">鎖死現(xiàn)象,通常在開到頂點位置上,再倒回1/2－1圈,作為全開閥門的位置。因此,閥門的全開位置，按閘板的位置（即行程〉來確定。有的閘閥閥桿螺母設(shè)在閘板上，手輪轉(zhuǎn)動帶動閥桿轉(zhuǎn)動，而使閘板提升。</span> 固原閘閥聯(lián)系人</p><p
