J41TC陶瓷截止閥簡述:
J41TC陶瓷截止閥主要采用陶瓷閥座、陶瓷閥芯構(gòu)造。陶瓷閥芯由流線型節(jié)流錐,陶瓷密封圈、軟密封圈和彈性橡膠環(huán)組成,利用流線型節(jié)流錐調(diào)節(jié)流道面積,達(dá)到流量調(diào)節(jié)目的;閥芯采用軟質(zhì)、硬質(zhì)雙重密封,大大提高密封性能,可達(dá)零泄漏;流線型節(jié)流錐的延伸面包容閥芯軟密封面,介質(zhì)沿錐面斜向流動(dòng),可避免直接沖刷閥芯密封面。工業(yè)陶瓷節(jié)流截止閥采用特種陶瓷密封材料,使閥壽命延長數(shù)倍。
適用于公稱壓力PN1.6~32.0Mpa及P54170V,工作溫度-29~540℃的石油、化工、礦山、冶金、電力行業(yè)等各種工況的管路上,切斷或接通管路介質(zhì)。特別是用于排灰、排渣系統(tǒng),放料、排污系統(tǒng)中,其使用壽命比普通合金密封面閥門提高10倍以上。
