气动控制阀的结构特性
气动控制阀的结构可分解成阀体(包含阀座和阀孔等)和阀心两部分，根据两者的相对位置，有常闭型和常开型两种。阀从结构上可以分为：截止式、滑柱式和滑板式三类阀。
（一）截止式阀的结构及特性
截止式阀的阀心沿着阀座的轴向移动，控制进气和排气。图4.2所示为二通截止式阀的基本结构。图4.2a中，在阀的P口输入工作气压后，阀芯在弹簧和气体压力作用下紧压在阀座上，压缩空气不能从A口流出；图4.2b为阀杆受到向下的作用力后，阀芯向下移动，脱离阀座，压缩空气就能从P口流向A口输出。这就是截止式阀的切换原理。
下离开阀座，压缩空气从P口流向A口输出。图4.3b为工作状态，阀杆在向上的力作用下，阀心紧压在阀座上关闭阀口，流道被关断，A口没有压缩空气流出。
图4.4所示为三通截止式阀的结构，阀有P、A、0三个孔口。图4.4a为阀的初始状态，阀心紧压在上阀座上，P口和A口通路被关断，A口和0口相通。阀的输出A口没有输出。

2FRM 10-3X/5LBV 图4.4b为工作状态。阀杆受力后使阀心离开上阀座而紧压在下阀座上，关闭排气O口，打开P口至A口之间的通道，压缩空气从P口流向A口输出。图4.4c所示为阀在切换过程中阀心所处的瞬态位置。此时，P、A、0三个孔口同时相通，而发生串气现象。实际上，对于快速切换的阀，这种串气现象对阀的动作不存在什么影响。但缓慢切换时，应予以注意。
截止式阀的结构决定了其开启所需的时间较短，但开启大口径的阀则需较大的开启力。因此截止式阀多用于小口径的阀。需要大流量或高压时，往往采取先导式的结构。其方法是增加一个控制活塞，先导控制气压作用在活塞上产生的较大操纵力，以弥补上述缺点。2FRM 6 SB76-3X/16QRV
