閥芯，閥芯是調(diào)節(jié)閥工作時的可動部件，受介質(zhì)的沖刷，腐蝕較為嚴重，檢修時要認真檢查閥芯各部分是否被腐蝕，磨損，特別是高壓差的情況下閥芯的磨損更為嚴重，（因汽蝕現(xiàn)象）應(yīng)予注意。閥芯損壞嚴重時應(yīng)進行更換。另外還應(yīng)注意閥桿是否也有類似的現(xiàn)象，或與閥芯連接松動等。 4. “O"型密封圈和其他密封墊是否老化，江蘇單座調(diào)節(jié)閥采購，裂損。 5. 應(yīng)注意聚四氟乙烯填料，密封潤滑油脂是否老化，配合面是否被損壞，應(yīng)在必要時更換。調(diào)節(jié)閥泄露一般包括內(nèi)漏、填料泄露、閥芯和閥座變形導(dǎo)致的泄露。江蘇單座調(diào)節(jié)閥采購</p><div

除了蝶閥和隔膜閥在結(jié)構(gòu)上完全對稱外，所有其他結(jié)構(gòu)的調(diào)節(jié)閥都是不對稱的。當調(diào)節(jié)閥改變流動方向時，由于流路的變化會引起)值變化。各類調(diào)節(jié)閥的正常流向均為使閥芯打開的方向(正向使用)，生產(chǎn)廠也只提供正常流向時的流通能力)值和流量特性。當調(diào)節(jié)閥反向使用時，既流體沿著使閥芯關(guān)閉的方向流動時，調(diào)節(jié)閥的流通能力會增大。水聯(lián)動試車時，模擬工藝條件不可能很快達到正常狀態(tài)，調(diào)節(jié)閥在較長時間內(nèi)處于小開度狀態(tài)下使用，由于不平衡力的作用，會出現(xiàn)嚴重的不穩(wěn)定。所以調(diào)節(jié)閥會產(chǎn)生強烈的震蕩并發(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)閥的開度是適中的，即使小開度也是短暫的，所以調(diào)節(jié)閥可正常安全使用。江蘇套筒調(diào)節(jié)閥種類有哪些調(diào)節(jié)閥的維護與一般儀表的維護類似，可分為被動性維護、預(yù)防性維護和預(yù)見性維護。</p><div
