【產(chǎn)品用途】
J41H、J41Y、J41W API美標(biāo)截止閥的啟閉件是圓柱形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運(yùn)動(dòng)。國(guó)標(biāo)截止閥只適用于全開(kāi)和全關(guān),一般不用來(lái)調(diào)節(jié)流量,定做時(shí)允許作調(diào)節(jié)和節(jié)流。
【產(chǎn)品特點(diǎn)】
1、結(jié)構(gòu)簡(jiǎn)單,制造和維修比較方便
2、工作行程小,啟閉時(shí)間短
3、密封性好,密封面間磨擦力小,壽命較長(zhǎng)
【執(zhí)行標(biāo)準(zhǔn)】
設(shè)計(jì)標(biāo)準(zhǔn) BS1873 JIS B2071-2081
結(jié)構(gòu)長(zhǎng)度 ANSI B16.10,JISB2002
配管法蘭 ANSI B16.5、JIS B2212-2214
對(duì)焊端尺寸 ANSI B16.25
檢驗(yàn)與試驗(yàn) API598、JIS B2003
傳動(dòng)方式 手動(dòng)、電動(dòng)、傘齒輪動(dòng)
