J61W-300LB美標(biāo)焊接截止閥作為管路啟閉裝置用來隔斷或?qū)ü苈分械慕橘|(zhì)。截止閥的啟閉件是塞形的閥瓣,密封面呈平面或錐面,在啟閉過程中閥瓣沿流體的中心線作直線運(yùn)動(dòng)。
截止閥與閘閥相比具有以下優(yōu)點(diǎn):1,結(jié)構(gòu)簡單,便于維修;2,工作行程短,啟閉時(shí)間快(閥瓣開啟高度為公稱直徑的0.2~0.3);3,密封性好,密封面間摩擦力小,壽命長。
公司設(shè)計(jì)制造的鋼制截止閥,品種齊全,性能優(yōu)越,輕便靈活,外觀精美,牢固耐用。
適用介質(zhì):水、蒸汽、油品、硝酸、醋酸、強(qiáng)氧化介質(zhì)及尿素等等。廣泛應(yīng)用于石油,化工、電力、冶煉、制藥、輕工、紡織等行業(yè)??膳c進(jìn)口設(shè)備直接配套、安裝使用
