不銹鋼美標(biāo)截止閥的產(chǎn)品概述
截止閥是一種常用的截?cái)嚅y,主要用來(lái)接通或截?cái)喙苈分械慕橘|(zhì),一般不用于調(diào)節(jié)流量。截止閥適用的壓力、溫度范圍很大,但一般用于中、小口徑的管道。
不銹鋼美標(biāo)截止閥的產(chǎn)品特點(diǎn)
①產(chǎn)品的設(shè)計(jì)制造符合美國(guó)國(guó)家標(biāo)準(zhǔn)ANSI BI16.34,英國(guó)國(guó)家標(biāo)準(zhǔn)BS1873等*進(jìn)標(biāo)準(zhǔn)要求。
②閥體外型為桶形或流線形,造形美觀,流道形狀為直通式,流體阻力小。
③關(guān)閉件(閥瓣)與閥座密封采用錐面密封,關(guān)閉力小,耐沖刷,密封可靠。
④閥座可為更換式閥座,可任意組合與關(guān)閉件密封面材料的配對(duì),以滿足各種工況要求,延長(zhǎng)使用壽命。
