產(chǎn)品概述:
電動(dòng)法蘭球閥是一種轉(zhuǎn)角90°旋轉(zhuǎn)類球閥,密封性能優(yōu)良,流通能力大,流阻系數(shù)小,結(jié)構(gòu)簡單,維修方便,使用壽命長,閥體通道和連接管徑相等并成一直徑,介質(zhì)幾乎可以毫無損失的流過,配用Q系列執(zhí)行機(jī)構(gòu),產(chǎn)品通常用于密封要求嚴(yán)格的場(chǎng)合,除控制氣體.液體.蒸汽介質(zhì)外,還適宜控制水含有纖維雜質(zhì)的介質(zhì),廣泛應(yīng)用于石油.化工.冶金.輕工、造紙、電站、制冷等工作領(lǐng)域。
性能特點(diǎn):
1.流體阻力小,球閥是所有閥類中流體阻力最小的一種,即使是縮頸球閥,其流體阻力也相當(dāng)小。
2.止推軸軸承減少閥桿摩擦力矩,可使閥桿長期操作平衡靈活。
3.閥座密封性能好,采用聚四氟乙烯等材料制成的密封圈,結(jié)構(gòu)易于密封,而且球閥的密封能力隨著介質(zhì)壓力的增大而增大。
4.閥座密封可靠,由于閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)而不做升降運(yùn)動(dòng),閥桿的填料密封不易破壞,且密封能力隨介質(zhì)的壓力增設(shè)而增大。
5.由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的摩擦損失小,球閥的使用壽命更長。
