截止閥閥門尺寸

1、0詳細介紹：國標(biāo)法蘭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動。 國標(biāo)截止閥只適用于全開和全關(guān)，一般不用來調(diào)節(jié)流量，定做時允許作調(diào)節(jié)和節(jié)流。公稱壓力，工作溫度-29550C的石油、化工、制藥、化肥、電力行業(yè)等各種工況的管路上，切斷或接通管路介質(zhì)。驅(qū)動方式有手動、齒輪傳動、電動、氣動等。國標(biāo)法蘭截止閥產(chǎn)品特點1、結(jié)構(gòu)簡單，制造和維修比較方便2、工作行程小，啟閉時間短3、密封性好，密封面間磨擦力小，壽命較長國標(biāo)法蘭截止閥執(zhí)行標(biāo)準(zhǔn)設(shè)計規(guī)范：GB/T 12235結(jié)構(gòu)長度：GB/T 12221法蘭連接：JB/T 79試驗與檢驗：JB/T 9002產(chǎn)品標(biāo)識：GB/T
