閥門是氣力輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。用于流體控制系統(tǒng)的閥門，從簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格相當(dāng)繁多。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。材質(zhì)：閥門根據(jù)材質(zhì)還分為鑄鐵閥門，鑄鋼閥門，不銹鋼閥門，鉻鉬鋼閥門，鉻鉬釩鋼閥門，雙相鋼閥門，塑料閥門，非標(biāo)訂制等閥門材質(zhì)。閥門本體的材質(zhì)要求推薦是以球墨鑄鐵為主，閥門的閥桿材質(zhì)推薦使用不銹鋼。對(duì)于螺母的材質(zhì)硬度要求要大于閥桿，采用鑄鋁黃銅或鑄鋁青銅，至于閥桿襯套的材質(zhì)硬度不能大于閥桿，在遇水的情況下要求不能與閥桿和閥體產(chǎn)生電化學(xué)腐蝕。種類：氣力輸送是以壓縮氣源為輸送動(dòng)力,將粉狀物料在密閉容器中從一端輸送到另外一端。氣力輸送所應(yīng)用的行業(yè)非常***,如電廠的煤粉、粉煤灰和爐底渣,化工行業(yè)的化工原料,建筑行業(yè)的水泥和石灰,食品醫(yī)藥衛(wèi)生等行業(yè)的各種粉料或顆粒物料等。而各種閥門的合理選用在氣力輸送中是至關(guān)重要的。閥門要滿足各行業(yè)氣力輸送的需求,應(yīng)具有耐溫、耐腐蝕和耐磨損等各方面的優(yōu)良性能。根據(jù)閥門在系統(tǒng)中的位置及作用。宿州水管閥門報(bào)價(jià)彈性座封閘閥底部采用與管道相同的平底設(shè)計(jì)，不易造成雜物淤積，使流體暢通無阻。</p><div

閘閥也叫閘板閥,是一種***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。它的優(yōu)點(diǎn)是:流體阻力小,啟閉省勁,可以在介質(zhì)雙向流動(dòng)的情況下使用,沒有方向性,全開時(shí)密封面不易沖蝕,結(jié)構(gòu)長度短,不僅適合做小閥門,而且適合做大閥門。閘閥按閥桿螺紋分兩類,一是明桿式,二是暗桿式。按閘板構(gòu)造分,也分兩類,一是平行,二是模式。2.截止閥截止閥,也叫截門,是使用*****的一種閥門,它之所以廣受歡迎,是由于開閉過程中密封面之間摩擦力小,比較耐用,開啟高度不大,制造容易,維修方便,不僅適用于中低壓,而且適用于高壓。它的閉合原理是,依靠閥杠壓力,使閥瓣密封面與閥座密封面緊密貼合,阻止介質(zhì)流通。截止閥只許介質(zhì)單向流動(dòng),安裝時(shí)有方向性。它的結(jié)構(gòu)長度大于閘閥,同時(shí)流體阻力大,長期運(yùn)行時(shí),密封可靠性不強(qiáng)。截止閥分為三類:直通式、直角式及直流式斜截止閥。3.蝶閥蝶閥也叫蝴蝶閥,顧名思義,它的關(guān)鍵性部件好似蝴蝶迎風(fēng),自由回旋。蝶閥的閥瓣是圓盤,圍繞閥座內(nèi)的一個(gè)軸旋轉(zhuǎn),旋角的大小,便是閥門的開閉度。蝶閥具有輕巧的特點(diǎn),比其他閥門要節(jié)省材料,結(jié)構(gòu)簡單,開閉迅速。以便能在較遠(yuǎn)處判別閥門的開度，及時(shí)采取相應(yīng)措施。啟閉迅速可靠，故常應(yīng)用于消防系統(tǒng)。宿州水管閥門報(bào)價(jià)</p><p
