本文介绍一种组合式单气控换向阀。它具有二进制计数功能,即气控口每次气动脉冲信号的上升沿触发换向阀换向,并具有双稳态和记忆的特性。一、原理图1是两位五通单气控滑柱式无弹簧换向阀。P 为主气路接口,A、B 分别接气缸两腔,C、D 为排气口,S 为控制口,设计时应满足P_1S_2>PS_3>P_1S_1 (1)式中P——主气路压力P_1——控制压力(1)当气控口无气时,L 端T 形阀芯封盖住面积为S_1的小孔(图1(α)所示),主阀芯在R 端极限位置(档块限位),气缸处于一种稳定状态;(2)当气控口S 有气时,R 端T 形阀芯
This article describes a combination of single-control valve. It has a binary counting function, that is, the pneumatic port triggers the commutation valve to change direction every time the pneumatic pulse signal rises, and has the characteristics of bistability and memory. First, the principle of Figure 1 is a two-way five-way control-free strut valve spring-free. P is the main air interface, A, B are connected to the cylinder chamber, C, D for the exhaust port, S for the control port design should meet P_1S_2> PS_3> P_1S_1 (1) where P - the main gas pressure P_1 - Control Pressure (1) When the air control port is empty, the L-shaped T-spool covers the small hole with the area of S_1 as shown in Fig. 1 (a) Block limit), the cylinder is in a steady state; (2) when the gas port S has gas, the R-T-shaped spool
