    • A valve operating system that includes a drive shaft, a drive lever that is fixedly provided thereon and can pivot in a direction of movement of a valve body, a follower arm that is fixedly provided on the valve body, a link, a first connecting shaft that connects one end of the link and the drive lever, and a second connecting shaft that connects the other end of the link and the follower arm; in response to a movement of the valve body from a first position to a second position by pivoting of the drive lever, a center of the first connecting shaft approaches from one side a straight line connecting two centers of the drive shaft and the second connecting shaft, and after the valve body reaches the second position, further pivoting of the drive lever is carried out through a predetermined angle so that the center of the first connecting shaft moves to the other side of a dead point on the straight line. Thereby a valve body can be held at one position with hardly any dependence on the output of an actuator, thus greatly reducing the load on the actuator.
    • 一种阀操作系统,包括驱动轴,固定地设置在其上并能够在阀体的运动方向上枢转的驱动杆,固定地设置在阀体上的从动臂,连杆,第一连接轴 连接所述连杆的一端和所述驱动杆;以及第二连接轴,其连接所述连杆的另一端和所述从动臂; 响应于通过驱动杆的枢转使阀体从第一位置移动到第二位置,第一连接轴的中心从连接驱动轴和第二连接轴的两个中心的直线的一侧接近 并且在阀体到达第二位置之后,驱动杆的进一步枢转以预定角度被执行,使得第一连接轴的中心移动到直线上的死点的另一侧。 因此,阀体可以保持在一个位置,几乎不依赖于致动器的输出,因此大大减小了致动器的负载。

    • A manipulator arm mechanism includes a pivot shaft, a first arm, a second arm, and an actuator. The first arm includes a first end and a second end opposite to the first end. The second arm also includes a first end and a second end opposite to the first end. The pivot shaft is connected to the first end of the first arm, and the pivot shaft has a first axis. The first end of the second arm is rotatably connected to the second end of the first arm and rotates around a second axis, and an angle between the first axis and the second axis is between 0° to 180°. The actuator is connected to the second end of the second arm.
    • 操纵臂机构包括枢转轴,第一臂,第二臂和致动器。 第一臂包括与第一端相对的第一端和第二端。 第二臂还包括与第一端相对的第一端和第二端。 枢转轴连接到第一臂的第一端,枢轴具有第一轴线。 第二臂的第一端可旋转地连接到第一臂的第二端并围绕第二轴线旋转,并且第一轴线与第二轴线之间的角度在0°至180°之间。 致动器连接到第二臂的第二端。
