J41H-150LB美標(biāo)鑄鋼截止閥介紹
J41H-150LB美標(biāo)鑄鋼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。適用于公稱壓力PN1.6~16MPa,工作溫度-29~550℃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。
J41H-150LB美標(biāo)鑄鋼截止閥特點
1、閥體外形為球形或流線形造型美觀。流通形狀為直通式,流體阻力小。
2、閥瓣和閥座密封副采用錐面密封,密封可靠,雜物不易落在密封面上,關(guān)閉力小,耐沖刷,密封可靠,
3、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。
4、大口徑、高壓力截止閥根據(jù)關(guān)閉力的需要閥桿的傳動方式采用升降桿,并配有滾動軸承式采用傘齒輪以減輕關(guān)閉力。
5、閥體、閥瓣、閥桿、填料、緊固件的材料可按實際工況要求合理選配,以適用于多種不同的工況環(huán)境。
