确保没有外来颗粒从油箱的通气盖、油滤的塞座、回油管路的密封垫圈以及油箱其他开口处进入油箱。,液压阀是一种用压力油操作的自动化元件，它受配压阀压力油的控制，通常与电磁配压阀组合使用，可用于远距离控制水电站油、气、水管路系统的通断。常用于夹紧、控制、润滑等油路。有直动型与先导型之分，多用先导型。
液压传动中用来控制液体压力、流量和方向的元件。其中控制压力的称为压力控制阀，控制流量的称为流量控制阀，控制通、断和流向的称为方向控制阀。

按用途分为单向阀和换向阀。单向阀：只允许流体在管道中单向接通，反向即切断。换向阀：改变不同管路间的通、断关系、根据阀芯在阀体中的工作位置数分两位、三位等；根据所控制的通道数分两通、三通、四通、五通等；根据阀芯驱动方式分手动、机动、电动、液动等。图2为三位四通换向阀的工作原理。P 为供油口，O 为回油口，A 、B 是通向执行元件的输出口。当阀芯处於中位时，全部油口切断，执行元件不动；当阀芯移到右位时，

P 与A 通，B 与O 通；当阀芯移到左位时，P 与B 通，A 与O 通。这样，执行元件就能作正、反向运动。 60年代后期，在上述几种液压控制阀的基础上又研制出电液比例控制阀。它的输出量(压力、流量)能随输入的电信号连续变化。电液比例控制阀按作用不同，相应地分为电液比例压力控制阀、电液比例流量控制阀和电液比例方向控制阀等。1）螺纹连接阀门

这种连接通常是将阀门进出端部加工成锥管或直管螺纹，可使其连接到锥管螺纹接头或管路上。由于这种连接可能出现较大的泄漏沟道，故可用密封剂、密封胶带或填料来堵塞这些沟道。如果阀体的材料是可以焊接的，但膨胀系数差异很大，或者工作温度的变化幅度范围较大，螺纹连接部必须进行蜜封焊。螺纹连接的阀门主要
