閘閥按閥桿的構(gòu)造可分為：1、明桿閘閥：閥桿螺母在閥蓋或支架上，開閉閘板時(shí)，用旋轉(zhuǎn)閥桿螺母來實(shí)現(xiàn)閥桿的升降。這種結(jié)構(gòu)對(duì)閥桿的潤(rùn)滑有利，開閉程度明顯，因此被采用。2、暗桿閘閥：閥桿螺母在閥體內(nèi)，與介質(zhì)直接接觸。開閉閘板時(shí)，用旋轉(zhuǎn)閥桿來實(shí)現(xiàn)。這種結(jié)構(gòu)的優(yōu)點(diǎn)是：閘閥的高度總保持不變，因此安裝空間小，適用于大口徑或?qū)Π惭b空間受限制的閘閥。此種結(jié)構(gòu)要裝有開閉指示器，以指示開閉程度。這種結(jié)構(gòu)的缺點(diǎn)是：閥桿螺紋不*無法潤(rùn)滑，而且直接接受介質(zhì)侵蝕，容易損壞。明桿閘閥和暗桿閘閥的主要區(qū)別：1、暗桿法蘭閘閥的提升螺桿是只旋轉(zhuǎn)而無上和下移動(dòng)，外露的只是一根桿，其螺母是固定在閘板上，通過螺桿的旋轉(zhuǎn)來提升閘板，沒有可見的門架;明桿法蘭閘閥的提升螺桿是外露的，螺母緊貼手輪且是固定的（不旋轉(zhuǎn)也不軸向移動(dòng)），通過旋轉(zhuǎn)螺桿來提升閘板，螺桿與閘板只有相對(duì)的旋轉(zhuǎn)運(yùn)動(dòng)而無相對(duì)的軸向位移，外觀為有門形支架。2、暗桿閥門看不見絲杠，而明桿的能看見絲桿。3、暗桿閥門在開關(guān)時(shí)方向盤與閥桿是連接在一起相對(duì)不動(dòng)的，它是通過閥桿在固定點(diǎn)轉(zhuǎn)動(dòng)來帶動(dòng)閥瓣向上提升和下閘來完成啟閉的。明桿閥門則是通過閥桿與方向盤的螺紋傳動(dòng)來提升或者降下閥瓣。貴陽(yáng)黑閘閥批發(fā)價(jià)格買軟密封閘閥就到〔眾海消防〕!廠家報(bào)價(jià)低!地域用戶都在看!</p><div

球型止回閥的選用1、止回閥一般適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)。2、對(duì)于DN50mm以下的低壓止回閥，宜選用蝶式止回閥、立式升降止回閥和隔膜式止回閥；對(duì)于DN大于200mm、小于1200mm的中低壓止回閥，宜選用無磨損球形上回閥；對(duì)于DN大于50mm、小于2000mm的低壓止回閥，宜選用蝶式止回閥和隔膜式止回閥。3、隔膜式止回閥適用于易產(chǎn)生水的管路上，隔膜可以很好地消除介質(zhì)逆流時(shí)產(chǎn)生的水，但受溫度和壓力限制，一般使用在低壓常溫管道上4、對(duì)于要求關(guān)閉時(shí)水沖擊比較小或無水的管路，宜選用緩閉旋啟式止回閥和緩閉蝶式止回閥。5、對(duì)于水泵進(jìn)口管路，宜選用底閥，底閥一般只安裝在泵進(jìn)口的垂直管道上，并且介質(zhì)自下而上流動(dòng)；6、升降式較旋啟式密封性好，流體阻力大，臥式宜裝在水平管道上，立式裝在垂直管道上；7、旋啟式止回閥的安裝位置不受限制，它可裝在水平、垂直或傾斜的管線上，如裝在垂直管道上，介質(zhì)流向要由下而上；8、旋啟式止回閥不宜制成小口徑閥門、可以做成很高的工作壓力，公稱壓力可達(dá)到42MPa，而且公稱通徑也可以做到很大，比較大可以達(dá)到2000mm以上。根據(jù)殼體及密封件的材質(zhì)不同可以適用任何工作介質(zhì)和任何工作溫度范圍。不銹鋼球閥大家都去〔眾海消防〕采購(gòu)啦!貴州閥批發(fā)價(jià)格</p><p

眾海消防推薦：不銹鋼電動(dòng)球閥閥門安裝的要點(diǎn)！1.方向和位置許多閥門具有方向性例如截止閥、節(jié)流閥、減壓閥、止回閥等，如果裝倒裝反，就會(huì)影響使用效果與壽命（如節(jié)流閥），或者根本不起作用（如減壓閥），甚至造成危險(xiǎn)（如止回閥）。一般閥門，在閥體上有方向標(biāo)志。萬(wàn)一沒有，應(yīng)根據(jù)閥門工作原理，正確識(shí)別。截止閥的閥腔左右不對(duì)稱，流體要讓其由下而上通過閥口，這樣流體阻力?。ㄓ尚螤钏鶝Q定），開啟省力（因介質(zhì)壓力向上），關(guān)閉后介質(zhì)不壓填料，便于檢修，這就是截止閥為什么不可安反的道理。其它閥門也有各自的特性。閥門安裝位置，必須方便于操作即使安裝暫時(shí)困難些，也要為操作人員的長(zhǎng)期工作著想。比較好閥門手輪與胸口取齊（一般離操作地坪），這樣，開閉閥門比較省勁。落地閥門手輪要朝上，不要傾斜，以免操作別扭?？繅C(jī)靠設(shè)備的閥門，也要留出操作人員站立余地。要避免仰天操作，尤其是酸堿、有毒介質(zhì)等，否則很不安全。閘門不要倒裝（即手輪向下），否則會(huì)使介質(zhì)長(zhǎng)期留存在閥蓋空間，容易腐蝕閥桿，而且為某些工藝要求所禁忌。同時(shí)更換填料極不方便。明桿閘閥，不要安裝在地下，否則由于潮濕而腐蝕外露的閥桿。升降式止回閥，安裝時(shí)要保證其閥瓣垂直。貴陽(yáng)黑閘閥批發(fā)價(jià)格</p><p
