鍛鋼焊接截止閥、焊接式鍛鋼截止閥適用于ANSIClass1500~2500Lb,工作溫度-29~570℃的石油、化工、火力電站等各種工況的管路上,切斷或接通介質(zhì)。適用介質(zhì)為:水、蒸汽等。操作方式有:手動、齒輪傳動、電動等。
二、進口鍛鋼焊接截止閥特征
截止閥的閥瓣一旦處于開啟狀況,它的閥座和閥瓣密封面之間就不再的接觸,并具有非??煽康那袛鄤幼鳎系眠@種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。截止閥一旦處于開啟狀態(tài),它的閥座和閥瓣密封面之間就不再有接觸,因而它的密封面機械磨損較小,由于大部分截止閥的閥座和閥瓣比較容易修理或更換密封元件時無需把整個閥門從管線上拆下來,這對于閥門和管線焊接成一體的場合是很適用的。介質(zhì)通過此類閥門時的流動方向發(fā)生了變化,因此截止閥的流動阻力較高于其它閥門。
截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關(guān)閉行程相對較短,并具有非??煽康那袛鄤幼鳎沟眠@種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。
三、選型:
1、高溫、高壓介質(zhì)的管路或裝置上宜選用截止閥。如火電廠、核電站,石油化工系統(tǒng)的高溫、高壓管路上。
2、管路上對流阻要求不嚴(yán)的管路上。即對壓力損失考慮不大的地方。
3、小型閥門可選用針閥、儀表閥、取樣閥、壓力計閥等。
4、有流量調(diào)節(jié)或壓力調(diào)節(jié),但對調(diào)節(jié)精度要求不高,而且管路直徑又比較小,如公稱通經(jīng)≤50mm的管路上,宜選用。
5、合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160公稱壓力16MPa或PN320公稱壓力32MPa的高壓角式截止閥或高壓角式節(jié)流閥。
6、氧化鋁拜耳法生產(chǎn)中的脫硅車間、易結(jié)焦的管路上,易選用閥體分開式、閥座可去處的、硬質(zhì)合金密封副的直流式截止閥或直流式節(jié)流閥。
7、城市建設(shè)中的供水、供熱工程上,公稱通經(jīng)較小的管路,可選用截止、平衡閥或柱塞閥,如公稱通經(jīng)小于150mm的管路上。

進口截止閥(stop valve,Globe Valve)的啟閉件是塞形的閥瓣,密封面呈平面或錐面,閥瓣沿閥座的中心線作直線運動。閥桿的運動形式,(通用名稱:暗桿),也有升降旋轉(zhuǎn)桿式,方工閥門根據(jù)閥瓣的這種移動形式,閥座通口的變化是與閥瓣行程成正比例關(guān)系。因此,這種類型的截流截止閥閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流用。Globe Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, the valve along the centerline of the valve seat for linear motion. Stem form of exercise, (generic name: dark bar), but also lift rotating rod, party work valve according to this form of valve, valve seat through the mouth of change is directly proportional relationship between the valve stroke. Therefore, this type of cut-off valve is suitable for cutting or regulation and throttle use由于該類閥門的閥桿開啟或關(guān)閉行程相對較短,而且具有非??煽康那袛喙δ埽钟捎陂y座通口的變化與閥瓣的行程成正比例關(guān)系,非常適合于對流量的調(diào)節(jié)。美國威盾VTON截止閥主要產(chǎn)品有鑄鋼截止閥,不銹鋼截止閥,法蘭截止閥,美標(biāo)截止閥,電動截止閥,球閥截止閥,鉻鉬鋼截止閥,高壓截止閥,高溫截止閥,高壓高溫截止閥,低溫截止閥,保溫截止閥,波紋管截止閥,德標(biāo)截止閥,美標(biāo)截止閥,日標(biāo)截止閥,開關(guān)截止閥,鍛鋼截止閥,焊接截止閥,對焊截止閥,承插焊截止閥等產(chǎn)品。
