調(diào)節(jié)閥內(nèi)漏后，要適當(dāng)調(diào)節(jié)閥桿的長(zhǎng)度，使閥桿長(zhǎng)度適合，不再產(chǎn)生內(nèi)漏；填料泄露后，為了使填料便捷，需要在填料函頂端倒角，在填料函底部加入防腐蝕、間隙較小的金屬保護(hù)環(huán)，金屬保護(hù)環(huán)與填料的接觸面不能使斜面，防止填料受介質(zhì)壓力而被推出。填料函與填料接觸部分的表面要進(jìn)行精加工，能夠提高表面光潔度，降低填料磨損。填料要選擇柔性石墨較佳，以內(nèi)柔性石墨的氣密封性高、摩擦力小、長(zhǎng)期使用后磨損小，并且容易維修，具有較高的耐壓性和耐熱性。閥芯和閥座變形泄露，要嚴(yán)格選擇閥芯和閥座的材質(zhì)，要選擇耐腐蝕性高材料，要將存在麻點(diǎn)、沙眼等缺陷的產(chǎn)品剔除掉，使閥芯和閥座有較高的密封光潔度，當(dāng)閥芯和閥座磨損、損壞嚴(yán)重時(shí)，要更換新閥。</p><p style="text-indent:25px">等百分比特性: 等百分比特性的相對(duì)行程和相對(duì)流量不成直線關(guān)系，在行程的每一點(diǎn)上單位行程變化所引起的流量的變化與此點(diǎn)的流量成正比，流量變化的百分比是相等的。所以它的優(yōu)點(diǎn)是流量小時(shí)，流量變化小，流量大時(shí)，則流量變化大，也就是在不同開(kāi)度上，具有相同的調(diào)節(jié)精度。線性特性: 線性特性的相對(duì)行程和相對(duì)流量成直線關(guān)系。單位行程的變化所引起的流量變化是不變的。流量大時(shí)，流量相對(duì)值變化小，流量小時(shí)，則流量相對(duì)值變化大。拋物線特性: 流量按行程的二方成比例變化，大體具有線性和等百分比特性的中間特性。從上述三種特性的分析可以看出，就其調(diào)節(jié)性能上講，以等百分比特性為較優(yōu)，其調(diào)節(jié)穩(wěn)定，調(diào)節(jié)性能好。而拋物線特性又比線性特性的調(diào)節(jié)性能好，可根據(jù)使用場(chǎng)合的要求不同，挑選其中任何一種流量特性。為了使調(diào)節(jié)閥正常工作，配用的執(zhí)行機(jī)構(gòu)要能產(chǎn)生足夠的輸出力來(lái)保證高度密封和閥門的開(kāi)啟。</p><div

除了蝶閥和隔膜閥在結(jié)構(gòu)上完全對(duì)稱外，所有其他結(jié)構(gòu)的調(diào)節(jié)閥都是不對(duì)稱的。當(dāng)調(diào)節(jié)閥改變流動(dòng)方向時(shí)，由于流路的變化會(huì)引起)值變化。各類調(diào)節(jié)閥的正常流向均為使閥芯打開(kāi)的方向(正向使用)，生產(chǎn)廠也只提供正常流向時(shí)的流通能力)值和流量特性。當(dāng)調(diào)節(jié)閥反向使用時(shí)，既流體沿著使閥芯關(guān)閉的方向流動(dòng)時(shí)，調(diào)節(jié)閥的流通能力會(huì)增大。水聯(lián)動(dòng)試車時(shí)，模擬工藝條件不可能很快達(dá)到正常狀態(tài)，調(diào)節(jié)閥在較長(zhǎng)時(shí)間內(nèi)處于小開(kāi)度狀態(tài)下使用，由于不平衡力的作用，會(huì)出現(xiàn)嚴(yán)重的不穩(wěn)定。所以調(diào)節(jié)閥會(huì)產(chǎn)生強(qiáng)烈的震蕩并發(fā)出刺耳的噪聲，因而導(dǎo)致閥芯很快斷裂。而在正常工藝條件下，調(diào)節(jié)閥的開(kāi)度是適中的，即使小開(kāi)度也是短暫的，所以調(diào)節(jié)閥可正常安全使用。江蘇套筒調(diào)節(jié)閥廠家排名</p><p
