在現(xiàn)代化工廠的自動控制中，調(diào)節(jié)閥起著十分重要的作用，這些工廠的生產(chǎn)取決于流動著的介質(zhì)正確分配和控制。這些控制無論是能量的交換、壓力的降低或者是簡單的容器加料，都需要某些較終控制元件去完成。讓調(diào)節(jié)閥一開始就盡量在較大開度上工作，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，這樣不斷破壞，逐步關(guān)閉，使整個閥芯全部充分利用，直到閥芯根部及密封面破壞，不能使用為止。同時，大開度工作節(jié)流間隙大，沖蝕減弱，這比一開始就讓閥在中間開度和小開度上工作提高壽命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。 </p><p style="text-indent:25px"> 一般較大流量下調(diào)節(jié)閥的開度應(yīng)在90%左右，較小流量下調(diào)節(jié)閥的開度不小于10%。開度驗算時必須考慮理想的調(diào)節(jié)閥流量特性和工作條件。下面給出兩種常用流量特性的調(diào)節(jié)閥在工作條件下(串聯(lián)管道)的開度驗算公式。目前，我國統(tǒng)一設(shè)計的調(diào)節(jié)閥，其理想可控比R一般均為30，但在使用時受較大開度和較小開度的限制，一般會使可控比下降到10左右。在串聯(lián)管道情況下，實際可控比Rc=R√S。因此，按下面的公式Rc=10√S進行可控比驗算,若Rc＞qmax/qmin時，則所選調(diào)節(jié)閥符合要求。否則，必須改變調(diào)節(jié)閥的S數(shù)值，可采取增加系統(tǒng)壓力或采用兩個控制閥(降低S數(shù)值)，進行分程控制的方法來滿足可控比要求。調(diào)節(jié)閥支撐使調(diào)節(jié)閥的各部件處于不受重力等影響的位置。</p><div
