國標(biāo)法蘭截止閥的啟閉件是圓柱形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運動。國標(biāo)截止閥只適用于全開和全關(guān),一般不用來調(diào)節(jié)流量,定做時允許作調(diào)節(jié)和節(jié)流。公稱壓力1.6MPa-16.0MPa,工作溫度-29~550℃的石油、化工、制藥、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)。上海申弘閥門有限公司主營閥門有:截止閥,電動截止閥,氣動截止閥,電動蝶閥,氣動蝶閥,電動球閥,氣動球閥,電動閘閥,氣動閘閥,電動調(diào)節(jié)閥,氣動調(diào)節(jié)閥,減壓閥。水力控制閥真空閥門、襯膠閥門、襯氟閥門。驅(qū)動方式有手動、齒輪傳動、電動、氣動等。法蘭連接的操作步驟與方法可以說是眾說紛紜,沒有什么統(tǒng)一標(biāo)準(zhǔn),主要還是因為在各個共板法蘭機(jī)廠家生產(chǎn)的法蘭型號標(biāo)準(zhǔn)不統(tǒng)一,本文將介紹標(biāo)準(zhǔn)配置下的法蘭連接的操作步驟和方法。

國標(biāo)法蘭截止閥管端和法蘭連接

??a.管子端頭的切割加工一般用鋸切或氧乙炔焰切割。管切口用彎尺檢查。管口端面應(yīng)與管子軸線垂直,偏斜不得大于1.5mm,如圖1所示。

管子端頭檢查 圖1

管子端頭檢查 圖1

??b.當(dāng)管端加工完,檢查合格后可組裝法蘭。組對時可用的法蘭彎尺檢查法蘭端面和管子軸線的垂直度,如圖2所示,將法蘭尺一端緊靠管皮,另一端靠緊法蘭面,然后在圓周上分三點將法蘭和管端點焊住。再用塞尺以兩個90℃的方向來測量法蘭尺和法蘭端面的間隙。其偏差不得超過法蘭外徑的0.15%,且不大于2mm。同時應(yīng)檢查管口捅人法蘭內(nèi)應(yīng)距法蘭密封面的距離,應(yīng)不小于管壁厚的1.3一1.5倍。若發(fā)現(xiàn)偏差超出允許值應(yīng)消除偏斜后再點焊。若檢查各項偏差均合乎要求,則可進(jìn)行管子和法蘭的焊接,焊接工藝必須符合技術(shù)要求。

??②法蘭與法蘭的連接
??a.操作步驟(以焊接法蘭為例)。檢查法蘭是否符合設(shè)計要求→管端加工預(yù)制→管端和法蘭組焊→墊片檢驗→墊片上涂密封涂料→法蘭緊固件的選配、檢驗,安裝前螺紋涂料處理→法蘭安裝組對、加墊初緊→管路平直度、錯邊址、法蘭平行度檢查→終緊。

??b.操作方法。在法蘭連接時,先初步找平找正,加墊初緊,然后再次檢驗平直度,必須保持墊片中心和管子軸線重合。確認(rèn)無誤后,用與螺栓相應(yīng)尺寸的扳手,按對稱的順序,分2-3遍逐個擰緊,如圖3所示。

產(chǎn)品特點

1、結(jié)構(gòu)簡單,制造和維修比較方便

2、工作行程小,啟閉時間短

3、密封性好,密封面間磨擦力小,壽命較長
