“上明”牌氣動美標(biāo)襯氟蝶閥是用隨閥桿一起轉(zhuǎn)動的蝶板做啟閉件,用以實(shí)現(xiàn)閥門開啟、關(guān)閉與調(diào)節(jié). 蝶閥在管路中除了起切斷和截流用外,近年來已經(jīng)把密封性能作為評價(jià)的主要指標(biāo),受到市場的青睞.另外,蝶閥還有體積小、重量輕、結(jié)構(gòu)簡單的優(yōu)點(diǎn),與同參數(shù)閘閥比較,平均減輕重量達(dá)30-50%,蝶板旋轉(zhuǎn)90°即可實(shí)現(xiàn)啟、閉過程,又由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用力近似相等,轉(zhuǎn)矩相反,因此啟閉力矩較小. 一、公司推出的氟塑料襯里蝶閥系列 1.其基本類型有兩種,即D71F4 和D71F46(中線)以及D71F4 和D71F46(偏心)全襯里型對夾式蝶閥,采用對分兩片閥式組合,閥座與閥體內(nèi)襯一體化,閥門工作時,只有全塑閥座與襯塑蝶板與介質(zhì)接觸,產(chǎn)品可承受"除熔融堿金屬和元素氟"外的任何介質(zhì)腐蝕,其中D71F4 閥桿也蝶板(鍛)為一體,表面均勻包裹一層FEP.閥體通道內(nèi)表面光滑,流體阻力小,CV值高,流通能力強(qiáng),扭矩適中,采用四級密封結(jié)構(gòu)并在密封面處配以耐溫抗老化SI橡膠的彈性襯墊閥座,*達(dá)到介質(zhì)的零泄露. 2.有上述型號擴(kuò)展而成的D71F和D41F型法蘭連接閥體全襯里,蝶板為不銹鋼的襯里型蝶閥. 3.D343F型法蘭連接雙偏心全襯里蝶閥. 二、結(jié)構(gòu)特點(diǎn) 1.中線蝶閥為整個蝶板與閥座在360°圓周內(nèi)同心(中線),具有雙向密封功能,壓力、流量可自由調(diào)節(jié); 2.偏心蝶閥為二維方向偏心產(chǎn)生的凸輪效應(yīng)會使密封副產(chǎn)生足夠的密封比壓,并且隨著工作壓力的升高,密封副產(chǎn)生足夠的密封比壓,并且隨著工作壓力的升高,密封效果更理想. 3.四級加載彈性密封,保證了閥門內(nèi)、外的零泄露; a.軸頭、蝶板圓周連接處的特殊過渡曲線與閥座的合理過盈; b.軸頭端面采用彈性O(shè)型圈和軸肩處剛性墊圈、彈性橡膠墊組合; c.軸的徑向采用O型圈與金屬墊的組合; d.閥座鑲在有彈性條的閥體槽內(nèi); 4.采用可調(diào)性彈子定位,定位準(zhǔn)確,結(jié)構(gòu)簡單. (*采用O型圈是為了防止意外泄漏時的安全措施) 5.法蘭連接雙偏心蝶閥試用于壓力較高場合. 三、設(shè)計(jì)規(guī)范 遵循GB 12238,API 609,MSS SP-67, MSS SP-68標(biāo)準(zhǔn). 四、驅(qū)動方式 手動、蝸輪轉(zhuǎn)動、氣動、電動. 對夾連接蝶閥(中線) · 設(shè)計(jì)與制造符合API美國石油學(xué)會標(biāo)準(zhǔn) · 基本結(jié)構(gòu)形式(*蝶板軸與閥體/閥座中心重合) a.DB 71F46全襯里型 閥體全襯里/蝶板全襯層/蝶板與蝶板軸和為一體; b.DB 71F4全襯里型 閥體全襯里/蝶板全襯層/蝶板與蝶板軸組合裝配; C.DB 71F半襯里型 閥體全襯里/蝶板為不銹鋼(不襯)蝶板與蝶板軸組合裝配。
