特點 | Characteristic |
目前國內(nèi)外截止閥大部分密封副都采用堆焊工藝,由于,管道中含有雜質(zhì)物,使閥門在啟閉壓壞密封,使截止閥過早失去密封性能。該產(chǎn)品密封副全部結構陶瓷制造。陶瓷具有高硬質(zhì),耐磨損,使用壽命長等特點。 | The domestle and Internatlonal stop valve seels palr and all adopts and plles the craft of welding mostly at pressent,because contaln the lmpurlty thing in the plpeline and make the valve open and close and damaglng by pressure sealing,make the stop valve lose the sealing property too early.This product seals a structure pottery to make.The pottery has high hard quallties,decresse wear-reslsting,characrerlstlo of having long performance life eto.. |
