在現(xiàn)代化工廠的自動(dòng)控制中，調(diào)節(jié)閥起著十分重要的作用，這些工廠的生產(chǎn)取決于流動(dòng)著的介質(zhì)正確分配和控制。這些控制無(wú)論是能量的交換、壓力的降低或者是簡(jiǎn)單的容器加料，都需要某些較終控制元件去完成。讓調(diào)節(jié)閥一開(kāi)始就盡量在較大開(kāi)度上工作，如90%。這樣，氣濁、沖蝕等破壞發(fā)生在閥芯頭部上。隨著閥芯破壞，流量增加，相應(yīng)閥再關(guān)一點(diǎn)，這樣不斷破壞，逐步關(guān)閉，使整個(gè)閥芯全部充分利用，直到閥芯根部及密封面破壞，不能使用為止。同時(shí)，大開(kāi)度工作節(jié)流間隙大，沖蝕減弱，這比一開(kāi)始就讓閥在中間開(kāi)度和小開(kāi)度上工作提高壽命1-5倍以上。如某化工廠采用此法，閥的使用壽命提高了2倍。上海套筒調(diào)節(jié)閥工作原理</p><p
