1.2 操作 ( 参见图 4.)
(G-O- 导阀 )
来自控制器的空气压力信号进入最下面的气压室，形成连杆向下的力达到与平衡弹簧平衡。 该运动传输到上挡板来打开和关闭喷嘴孔。经节流装置节流的供气输入背压腔，根据挡板的 运动增加或减小背压腔的压力，进而打开或关闭上导阀 (B)。当下导阀 (A) 打开时，供气将充 满气缸的上腔和主背压腔，使之压力等于供气压力。当阀门 (A) 关闭时，供气通过排气腔从 排气孔排出，压力降为零。进入主背压腔的空气压力与设定弹簧相抗衡，打开或关闭下导阀 (B)。当阀门 (B) 打开时，供气进入气缸的下腔。当关闭时，通过阀帽排到大气中。

G-O- 导阀 ( 参见图 4.)
G-O- 导阀由导向部分和反馈机构组成。导向部分由几个铝合金环、插入这些环中的隔膜以 及环和隔膜上的孔 ( 形成空气通道 ) 组成。反馈机构由铸铁腔室 ( 其中包含平衡弹簧、主梁、 辅助梁和装有滚珠组件的移动装置 )、凸轮板和活塞杆组成。气缸与导向部分之间仅通过铜 管相连。空气信号压力和供气口以及向两个气缸腔室的出气口安装在中心环上。在标准型 中，有两个压力表显示空气信号压力和供气压力。

反馈机构
由活塞杆的行程产生的弹簧张力通过主梁、移动装置和辅助梁反馈到导阀。通过改变移动 装置的位置改变传输到导向部分的行程，可控制活塞杆的行程，调零螺丝可改变初始弹簧 张力，决定活塞杆开始移动的空气信号压力。由于空气信号压力的范围为 20 至 100kPa (0.2 至 1.0kgf/cm2)，通过调零使活塞杆在空气信号压力为 20 kPa(0.2kgf/cm2) 时开始移动。

气缸的使用方法
气缸是一种常用的气动执行元件，广泛应用于工业自动化生产线、机器人、航空航天等领域。

在使用气缸时，需要注意以下几点：
1. 选择合适的气缸型号：根据需要执行的任务和工作环境条件，选
择适合的气缸型号，包括气缸的尺寸、工作压力、工作介质等。

2. 连接气源：将气缸与气源连接，通常使用气管或接头等连接件。

3. 安装气缸：根据具体任务的要求，将气缸安装在合适的位置上，
通常使用支架或固定座等固定件。

4. 调节气缸：根据具体任务的要求，调节气缸的行程、速度、力量
等参数，通常使用控制阀或压力调节器等控制元件。

5. 使用气缸：根据具体的控制方式，使用气缸完成相应的任务，例
如推动物体、抓取物体、旋转等。

除了以上基本使用方法外，还应注意气缸的维护保养，包括定期清洗和加油润滑等。

同时，为了确保安全使用，应严格遵循气缸的使用说明书和相关安全规范。
