工作原理DBW10B2-5X100比例阀
减压阀是气动调节阀的一个必备配件，主要作用是将气源的压力减 减压阀
压并稳定到一个定值，以便于调节阀能够获得稳定的气源动力用于调节控制。 按结构形式可分为薄膜式、弹簧薄膜式、活塞式、杠杆式和波纹管式；按阀座数目可人为单座式和双座式；按阀瓣的位置不同可分为正作用式和反作用式。
（一）直动式减压阀工作原理
直动式减压阀所示为直动式带溢流阀的减压阀(简称溢流减压阀)的结构图。压力为P1的压缩空气，由左端输入经阀口10节流后，压力降为P2输出。P2的大小可由调压弹簧2、3进行调节。顺时针旋转旋钮1，压缩弹簧2、3及膜片5使阀芯8下移，增大阀口10的开度使P2增大。若反时针旋转旋钮1，阀口10的开度减小，P2随之减小。若P1瞬时升高，P2将随之升高，使膜片气室6内压力升高，在膜片5上产生的推力相应增大，此推力破坏了原来力的平衡，使膜片5向上移动，有少部分气流经溢流孔12、排气孔11排出。在膜片上移的同时，因复位弹簧9的作用，使阀芯8也向上移动，关小进气阀口10，节流作用加大，使输出压力下降，直至达到新的平衡为止，输出压力基本又回到原来值。若输入压力瞬时下降，输出压力也下降、膜片5下移，阀芯8随之下移，进气阀口10开大，节流作用减小，使输出压力也基本回到原来值。逆时针旋转旋钮1。使调节弹簧2、3放松，气体作用在膜片5上的推力大于调压弹簧的作用力，膜片向上曲，靠复位弹簧的作用关闭进气阀口10。再旋转旋钮1，进气阀芯8的顶端与溢流阀座4将脱开，膜片气室6中的压缩空气便经溢流孔12、排气孔11排出，使阀处于无输出状态。总之，溢流减压阀是靠进气口的节流作用减压，靠膜片上力的平衡作 减压阀
用和溢流孔的溢流作用稳压；调节弹簧即可使输出压力在一定范围内改变。为防止以上溢流式减压阀徘出少量气体对周围环境的污染，可采用不带溢流阀的减压阀(即普通减压阀)。
（二）先导式减压阀工作原理
内部先导式减压阀当减压阀的输出压力较高或通径较大时，用调压弹簧直接调压，则弹簧刚度必然过大，流量变化时，输出压力波动较大，阀的结构尺寸也将增大。为了克服这些缺点，可采用先导式减压阀。先导式减压阀的工作原理与直动式的基本相同。先导式减压阀所用的调压气体，是由小型的直动式减压阀供给的。若把小型直动式减压阀装在阀体内部，则称为内部先导式减压阀；若将小型直动式减压阀装在主阀体外部，则称为外部先导式减压阀。与直动式减压阀相比，增加了由喷嘴4、挡板3、固定节流孔9及气室B所组成的喷嘴挡板放大环节。当喷嘴与挡板之间的距离发生微小变化时，就会使B室中的压力发生根明显的变化，从而引起膜片10有较大的位移，去控制阀芯6的上下移动，使进气阀口8开大或关小、提高了对阀芯控制的灵敏度，即提高了稳压精度。 在主阀体外部还有一个小型直动式减压阀由它来控制主阀。此类阀适于通径在20mm以上，远距离(30m以内)、高处、危险处、调压困难的场合。
