style="font-size:16px;">彈性座封閘閥又被稱為軟密封閘閥，是普通中低壓閥門的更新?lián)Q代的產(chǎn)品，被稱為綠色環(huán)保產(chǎn)品，被用于飲用水，給排水、污水處理、消防、能源系統(tǒng)等流體管道上作為截流裝置使用。彈性座封閘閥主要零部件有閥體、閥蓋、閥桿及閘板等，閘板采用球墨鑄鐵外全覆無(wú)毒橡膠（直接硫化丁腈橡膠或三元已有丙橡膠）制作而成。整個(gè)閥門的密封主要依靠橡膠閘板與鑄件接觸，通過(guò)橡膠因受力而產(chǎn)生微量彈性變形達(dá)到良好的效果，密封可靠，可達(dá)到零泄漏,而且摩擦因很小，磨損小，閥門在啟閉時(shí)力矩小，操作輕便，使用壽命長(zhǎng)，無(wú)污染，耐蝕且外形美觀。平底式閥座傳統(tǒng)的金屬閘閥常常在通水清洗后即因外物如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內(nèi)，容易造成無(wú)法開關(guān)緊密，而形成漏水現(xiàn)象。彈性座封閘閥采用內(nèi)腔底部無(wú)凹槽，</span><span style="font-size:16px;">底部與水管相同的平底設(shè)計(jì)，不易造成雜物淤積，密封始終如一。</span> </p><p> <span style="font-size:16px;">法蘭閘閥是連接方式為法蘭的閘閥，這種連接方式為常見(jiàn)。法蘭閘閥在管路中使用時(shí)穩(wěn)定可靠，所以在高壓管路上常采用法蘭閘閥。閘閥，就像一個(gè)閘門一樣，通過(guò)旋轉(zhuǎn)閥桿，控制閘板做上下垂直運(yùn)動(dòng)來(lái)控制流體，閘板兩邊的密封圈能完全密封整個(gè)截面，閘閥只能做全開和全關(guān)，不能作為調(diào)節(jié)流量的閥門使用；閘閥主要用在自來(lái)水，污水，船舶等管道上作為截流裝置使用閘閥流阻小，啟閉力小，開啟時(shí)間長(zhǎng)按閥桿分：明桿閘閥、暗桿閘閥按閘板分：平板閘閥（單、雙平板）、楔式閘閥（單、雙閘板）按中法蘭分：螺栓連接閥蓋、壓力密封閥蓋、螺紋焊接閥蓋閘閥適用于公稱壓力～（1兆帕=10公斤），工作溫度負(fù)二十九到六百攝氏度的石油、化工、化肥、電力行業(yè)等各種工況的管路上，切斷或接通管路介質(zhì)，不能作</span><span style="font-size:16px;">調(diào)節(jié)和節(jié)流。適用介質(zhì)為︰水、油品、蒸氣、酸性介質(zhì)等。</span> 閥桿有明桿和暗桿之分，明桿式閘閥適用于腐蝕介質(zhì)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="font-size:16px;">閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，叫升降桿閘閥(亦叫明桿閘閥)。通常在升降桿上有梯形螺紋，通過(guò)閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏Αｉ_啟閥門時(shí)，當(dāng)閘板提升高度等于閥門通徑的1：1倍時(shí)，流體的通道完全暢通，但在運(yùn)行時(shí)，此位置是無(wú)法監(jiān)視的。實(shí)際使用時(shí)，是以閥桿的頂點(diǎn)作為標(biāo)志，即開不動(dòng)的位置，作為它的全開位置。為考慮溫度變化出現(xiàn)鎖死現(xiàn)象,通常在開到頂點(diǎn)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(lái)確定。有的閘閥,閥桿螺母設(shè)在閘板上，手輪轉(zhuǎn)動(dòng)帶動(dòng)閥桿轉(zhuǎn)動(dòng),而使閘板提升,這種閥門叫做旋轉(zhuǎn)桿閘閥或叫暗桿閘閥。閘閥具有以下優(yōu)點(diǎn)1.流體阻力小,密封面受介質(zhì)的忡刷和侵蝕小。2.開閉較省力。3.介</span><span style="font-size:16px;">質(zhì)流向不受限制,不擾流、不降低壓力。4.形體簡(jiǎn)單,結(jié)構(gòu)長(zhǎng)度短，制造工藝性好，適用范圍廣。</span> 影響閥門正常開閉及調(diào)節(jié)阻力、壓力等功能。甚至造成系統(tǒng)運(yùn)行中，閥門損壞被迫修理。海北州閘閥公司</p><p
