1.2 液壓閥的功用及重要性
液壓控制閥（簡稱液壓閥）是液壓系統(tǒng)中的控制元件，其功用是控制液壓系統(tǒng)中液體的流向、壓力及流量，以使液壓執(zhí)行器及其驅動的工作機構獲得所需要的運動方向、運動速度（轉速）及推力（轉矩）等。
液壓閥在液壓系統(tǒng)中起著非常總要的作用。任何一個液壓系統(tǒng)，不論其如何簡單，都不能缺少液壓閥；同一工藝目的液壓機械設備，通過液壓閥的不同組合與使用，可以組成油路結構截然不同的多種液壓系統(tǒng)方案，股液壓閥是液壓技術中與規(guī)格最多、應用最廣泛、最活躍的元件；一個液壓系統(tǒng)設計的合理性、安裝維護的便利性以及能否按照既定要求正?？煽康剡\行，在很大程度上取決于其中所采用的各種液壓閥是性能優(yōu)劣及參數(shù)匹配是否合理。電磁閥的滑閥套與閥芯的配合間隙很小（小于0.008mm），一般都是單件裝配，當有機械雜質(zhì)帶入或潤滑油太少時，很容易卡住。處理方法可用鋼絲從頭部小孔捅入，使其彈回。根本的解決方法是要將電磁閥拆下，取出閥芯及閥芯套，用CCI4清洗，使得閥芯在閥套內(nèi)動作靈活。拆卸時應注意各部件的裝配順序及外部接線位置，以便重新裝配及接線正確，還要檢查油霧器噴油孔是否堵塞，潤滑油是否足夠。
（4）漏氣。漏氣會造成空氣壓力不足，使得強制閥的啟閉困難，原因是密封墊片損壞或滑閥磨損而造成幾個空腔竄氣。

1.3 液壓閥的基本結構原理
充液閥的基本結構主要包括閥芯、閥體和驅動閥芯在閥體內(nèi)作相對運動的操縱控制機構。閥芯的結構形式多樣;閥體上開設有與閥芯配合的閥體（套）孔或閥座孔，還有外接油管的進、出油口；閥芯的操縱控制機構有手調(diào)（動）式、機械式、電動式以及液動式或電液動式等。
液壓閥的基本工作原理是：利用閥芯相對于閥體的運動來控制閥口的通斷及開度的大?。▽嵸|(zhì)是對R901098531 4WSE3EE16-1X/150B9-210K9EV-118
