溢流阀是一种液压压力控制阀，在液压设备(http://www.maoyihang.com/sell/l_4/)中主要起定压溢流，稳压，系统卸荷和安全保护作用。溢流阀在装配或使用中，由于O形密封圈、组合密封圈的损坏，或者安装螺钉、管接头的松动，都可能造成不应有的外泄漏。如果锥阀或主阀芯磨损过大，或者密封面接触不良，还将造成内泄漏过大，甚至影响正常工作。
溢流阀的性能
静态性能
(1)压力调节范围
压力调节范围是指调压弹簧在规定的范围内调节时，系统压力能平稳地上升或下降，且压力无突跳及迟滞现象时的最大和最小调定压力。溢流阀的最大允许流量为其额定流量，在额定流量下工作时溢流阀应无噪声、溢流阀的最小稳定流量取决于它的压力平稳性要求，一般规定为额定流量的15％。
(2)启闭特性
启闭特性是指溢流阀在稳态情况下从开启后到闭合的过程中，被控压力与通过溢流阀的溢流量之间的关系。它是衡量溢流阀定压精度的一个重要指标，一般用溢流阀处于额定流量、调定压力ｐs时，开始溢流的开启压力ｐk及停止溢流的闭合压力ｐB分别与ｐs的百分比来衡量，前者称为开启比，后者称为闭合比。
电磁阀是由电磁线圈和磁芯组成，是包含一个或几个孔的阀体。当线圈通电或断电时，磁芯的运转将导致流体通过阀体或被切断，以达到改变流体方向的目的。电磁阀的电磁部件由固定铁芯、动铁芯、线圈等部件组成；阀体部分由滑阀芯、滑阀套、弹簧底座等组成。电磁线圈被直接安装在阀体上，阀体被封闭在密封管中，构成一个简洁、紧凑的组合。
