①產(chǎn)品的設(shè)計(jì)制造符合美國國家標(biāo)準(zhǔn)ANS1B16.34,美國BS1873等*進(jìn)標(biāo)準(zhǔn)要求。
②閥體外形為桶形或流線形造型美觀。流通形狀為直通式。流體阻力小。
③關(guān)閉件(閘瓣)與閥座密封面采用錐面密封,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)閉密封面材料的配對,以滿足工況的要求,延長使用壽命。
⑤大口徑、高壓力截止閥根據(jù)關(guān)閉力的需要閥桿的傳動(dòng)方式采用升降桿,并配有滾動(dòng)軸承式采用撞擊式手輪以減輕關(guān)閉力。
⑥主體材料、內(nèi)件材料、填料、緊固件的材料可按用戶要求或?qū)嶋H工況條件合理組合。
