J41H手動法蘭截止閥適用于石油、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)。適用介質(zhì)為:水、油品、蒸汽、酸性介質(zhì)等。操作方式有:手動、齒輪傳動、電動、氣動等。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,閥瓣沿流體的中心線作直線運動。閥桿的運動形式,有升降桿式(閥桿升降,手輪不升降),也有升降旋轉(zhuǎn)桿式(手輪與閥桿一起旋轉(zhuǎn)升降,螺母設(shè)在閥體上)。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。截止閥只適用于全開和全關(guān),不允許作調(diào)節(jié)和節(jié)流。
截止閥屬于強制密封式閥門,所以在閥門關(guān)閉時,必須向閥瓣施加壓力,以強制密封面不泄漏。當介質(zhì)由閥瓣下方進入閥門時,操作力所需要克服的阻力,是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力,關(guān)閥門的力比開閥門的力大,所以閥桿的直徑要大,否則會發(fā)生閥桿頂彎的故障。近年來,從自密封的閥門出現(xiàn)后,截止閥的介質(zhì)流向就改由閥瓣上方進入閥腔,這時在介質(zhì)壓力作用下,關(guān)閥門的力小,而開閥門的力大,閥桿的直徑可以相應地減少。同時,在介質(zhì)作用下,這種形式的閥門也較嚴密。我國閥門“三化給"曾規(guī)定,截止閥的流向,一律采用自上而下。
截止閥開啟時,閥瓣的開啟高度,為公稱直徑的25%~30%時,流量已達到zui大,表示閥門已達全開位置。所以截止閥的全開位置,應由閥瓣的行程來決定。 
化工部法蘭截止閥結(jié)構(gòu)特點: 
1、法蘭截止閥選材考究,符合國內(nèi)、外相關(guān)標準,結(jié)構(gòu)合理,造型美觀。
2、法蘭截止閥閥瓣、閥座密封面采用鐵基合金堆焊或司太立(Slite)鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫、耐腐蝕、抗擦傷性能好,使用壽命長。
4、法蘭截止閥閥桿經(jīng)調(diào)質(zhì)及表面氮化處理,有良好的抗腐蝕性和抗擦傷性。
5、法蘭截止閥可采用各種配管法蘭標準及法蘭密封面型式,滿足各種工程需要及用戶要求。
6、法蘭截止閥閥體材料品種齊全,填料、墊片可根據(jù)實際工況或用戶要求合理選配,能適用于各種壓力、溫度及介質(zhì)工況。 
7、法蘭截止閥倒密封采用螺紋連接密封座或本體堆焊奧氏體不銹鋼而成,密封可靠,更換填料可在不停機情況下進行,方便快捷,不影響系統(tǒng)運行。 


化工部法蘭截止閥產(chǎn)品特征

公稱壓力:1.6-6.4MPa

適用溫度范圍:≤200℃~≤350℃

適用介質(zhì):硝酸類、醋酸類、水、油、氣類及某些腐蝕性液體

的優(yōu)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。

法蘭截止閥的工作原理:

截止閥,也叫截門,是使用zui廣泛的一種閥門,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。

 截止閥的閉合原理是,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,安裝時有方向性。截止閥的結(jié)構(gòu) 長度大于閘閥,同時流體阻力大,長期運行時,密封可靠性 不強
