為什么直行程調(diào)節(jié)閥閥桿較細(xì)？它涉及一個(gè)簡(jiǎn)單的機(jī)械原理：滑動(dòng)摩擦大、滾動(dòng)摩擦小。直行程閥的閥桿上下運(yùn)動(dòng)，填料稍壓緊一點(diǎn)，它就會(huì)把閥桿包得很緊，產(chǎn)生較大的回差。為此，閥桿設(shè)計(jì)得非常細(xì)小，填料又常用摩擦系數(shù)小的四氟填料，以便減少回差，但由此派出的問題是閥桿細(xì)，則易彎，填料壽命也短。解決這個(gè)問題，比較好的辦法就是用旅轉(zhuǎn)閥閥桿，即角行程類的調(diào)節(jié)閥，它的閥桿比直行程閥桿粗2～3倍，且選用壽命長(zhǎng)的石墨填料，閥桿剛度好，填料壽命長(zhǎng)，什么是硬密封？切斷閥要求泄漏越低越好，軟密封閥的泄漏是比較低的，切斷效果當(dāng)然好，但不耐磨、可靠性差。從泄漏量又小、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。如全功能超輕型調(diào)節(jié)閥，密封而堆有耐磨合金保護(hù)，可靠性高，泄漏率達(dá)10～7，已經(jīng)能夠滿足切斷閥的要求。新疆止回閥價(jià)格烏魯木齊市耐酸堿閥門公司推薦。</p><div
