重慶升降平臺切斷閥透露越低越好，軟密封閥的透露是低的，切斷效果當(dāng)然好，但不耐磨、可靠性差。從透露量又小、密封又可靠的雙重標(biāo)準(zhǔn)來看，軟密封切斷就不如硬密封切斷好。
Wenzhou lift platform cut off valve to disclose the lower the better, soft sealing valve is disclosed is the lowest, cut off the effect is good, but not wear, reliability. From a small amount of small, sealed and reliable double standards, the soft seal cut off as hard as hard seal.
重慶升降平臺的切斷閥應(yīng)盡量選用硬密封，如全功用超輕型調(diào)節(jié)閥，密封而堆有耐磨合金維護(hù)，可靠性高，透露率達(dá)70%，曾經(jīng)能夠滿足切斷閥的懇求。
Wenzhou lift platform should be selected as the cut-off valve seal, such as full function ultra light valve, sealed and the pile has a wear-resistant alloy maintenance, high reliability, the rate reached 70%, has been able to meet the cut off valve.
