英國(guó)斯派莎克波紋管截止閥簡(jiǎn)介:
原裝英國(guó)斯派莎克波紋管截止閥BSA1T的口徑從DN15~DN250,可提供各種不同的材質(zhì),從鑄鐵材質(zhì)的BSA1T,球墨鑄鐵的BSA2T和鑄鋼材質(zhì)的BSA3T型截止閥,連接標(biāo)準(zhǔn)有法蘭、螺紋和承插焊等,壓力等級(jí)可達(dá)PN40,ANSI 300和CLASS 800。較高工作溫度可達(dá)425℃??捎糜诟邷叵到y(tǒng).從而用一種閥即可淮足各種不同的工業(yè)應(yīng)用要求,并確保長(zhǎng)的使用壽命、免維修及堅(jiān)固結(jié)實(shí)..
斯派莎克BSA64T采用不銹匯閥體,碳鋼閥帽。工常情況下,流體與閥帽不接觸。因此該閥適用于流體具有腐蝕性的環(huán)境。
斯派莎克BSA2T波紋管截止閥屬于強(qiáng)制密封式閥門(mén),所以在閥門(mén)關(guān)閉時(shí),必須向閥瓣施加壓力,以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門(mén)時(shí),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)的壓力所發(fā)生的推力,關(guān)閥門(mén)的力比開(kāi)閥門(mén)的力大,所以閥桿的直徑要大,否則會(huì)發(fā)生閥桿頂彎的故障。近年來(lái),從自密封的閥門(mén)出現(xiàn)后,截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔,這時(shí)在介質(zhì)壓力作用下,關(guān)閥門(mén)的力小,而開(kāi)閥門(mén)的力大,閥桿的直徑可以相應(yīng)地削減。同時(shí),在介質(zhì)作用下,這種方式的閥門(mén)也較嚴(yán)密。我國(guó)閥門(mén)“三化給”曾規(guī)定,截止閥的流向,一律選用自上而下。
斯派莎克BSA2T波紋管截止閥(SpiraxSarco)是指用在管道上的截止閥,他的啟閉件在于閥體于發(fā)辮之間、通過(guò)旋轉(zhuǎn)發(fā)干股動(dòng)發(fā)辮上生或下降來(lái)控制管道上的介質(zhì)、蒸汽截止閥管路中主要用來(lái)做堵截、分配和改變蒸汽的流動(dòng)方向。堵截管道上的介質(zhì)或調(diào)節(jié)介質(zhì)流量以及節(jié)流用。截止閥的閥桿開(kāi)啟或關(guān)閉行程相對(duì)較短,而且具有十分的堵截功能,又由于閥座通口的變化與閥瓣的行程成正比例聯(lián)系,十分適合于對(duì)蒸汽流量的調(diào)節(jié)。斯派莎克波紋管截止閥BSA1、BSA2、BSA3、BSA6T、BSA64T、A3S 、HV3截止閥、DBB3雙流雙關(guān)波紋管密封截止閥
斯派莎克BSA2T波紋管截止閥BSA波紋管密封截止閥選用獨(dú)特的波紋管密封規(guī)劃,從而完全消除了閥桿填料密封泄漏的問(wèn)題,滿(mǎn)意嚴(yán)格的泄漏等級(jí)要求。BSA型截止閥的零泄漏特性改進(jìn)了設(shè)備的安全性,節(jié)約大量能源,削減了維修費(fèi)用,并為工業(yè)應(yīng)用提供了清潔安全的工作環(huán)境。
BSA型截止閥的口徑從DN15-DN250,可提供各種不同的材質(zhì),從鑄鐵材質(zhì)的BSA1,球墨鑄鐵的BSA2和鑄鋼材質(zhì)的BSA3型截止閥連接標(biāo)準(zhǔn)有法蘭,螺紋和承插焊接等,壓力等級(jí)可達(dá)PN40,ANSI 300和CLASS 800。較高工作溫度可425C°,可用于高溫體系,從而用一種閥即可滿(mǎn)意各種不同的工業(yè)應(yīng)用要求,并確保長(zhǎng)的使用壽命,免維修及鞏固結(jié)實(shí)。
