0820215103气动减压阀

气动控制元件

气动基本回路是组成气动控制系统的基本单元，也是设计气动控制回路的基础。气动基本回路分为压力控制、速度控制和方向控制基本回路。

压力控制回路

压力控制回路的作用是调压和稳压。一次压力控制回路指用安全阀将空气压缩机的输出压力控制在 0.8MPa 左右。二次压力控制回路指把经一次调压后的压力 p1 再经减压阀减压稳压后所得到的输出压力p2（称为二次压力），作为气动控制 系统的工作气压使用。

高低压选择回路由多个减压阀控制，实现多个压力同时输出。

空气阀的功能

空气阀是管道的呼吸器，是管道安全的保障器，又称通气阀、排气阀，但它有吸气功能，故称空气阀较确切。空气阀分单排气功能的****空气阀，又称微量排气阀；兼有排气、进气功能的大口径空气阀，包括高速进排气空气阀、复合式空气阀等；单进气功能的空气阀，又称吸气阀、真空破坏阀。当向管道内充水时，管内的气体排出越快，充水的速度也就越快；若充水的水压过高，流速过快，空气阀迅速封球，容易产生水锤；当管道在排水过程中，若不及时通过空气阀或吸气阀（真空破坏阀）向管内吸进空气，一方面排水不畅，另一方面容易出现负压（形成真空现象）。对于常用的管材，这种负压不会造成危害。若一些管材的刚度不足，如大型薄壁钢管，容易引起管材几何形状的变形，造成漏水的故障，同时管外污水、污泥会抽吸至管内，危害供水安全。

准确减压阀——该阀门的减压比必须在一定程度上高于系统值； 即使在大或者小流量时它也应该能够对正作用或者反作用控制信号做出响应。这些阀门应该针对有用控制范围选择，即大流量的20%到80%。正常为等比型或者具有等比特性。这些类型的阀门本身具有比例控制所要求的佳流量特性及流量范围。

控制阀芯对应主阀芯的相反侧接触阻尼阀芯的凸台。为了打开主阀芯，油口X中的控制压力取决于腔中的弹簧。当阀打开时，该压力为20bar，全开时为50bar。开口面积，开启压力及开口压差之间的关系决定从B至A的从执行器排出的流量。这本身直接取决于执行器另一侧的进口流量，从而防止执行器“失控”。如果管子破裂发生在方向阀与平衡阀的油口A之间，则不影响负载下放操作。
