Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an angular stroke actuator with a rotary valve. Background Art

[0002] A rotary valve is a device used to control fluid or gas in a pipeline. It controls the passage of fluid or gas by rotating the valve disc. When the valve disc is aligned with the valve seat, the passage is fully open; when the valve disc is rotated to disalign with the valve seat, the passage is completely closed.

[0003] When the valve is opened and closed by electrical control, it is controlled by an angular stroke actuator, which usually consists of a motor, a transmission device and an output shaft connected to the rotary valve. When the angular stroke actuator works, the rotary valve will open or close.

[0004] However, the angular stroke actuators of rotary valves are mostly fixedly installed on the upper end of the valve body and cannot be adjusted in position. When the installation space is limited, the valve cannot be effectively installed and has low flexibility of use. Therefore, we propose an angular stroke actuator with a rotary valve to solve the existing problems. Utility Model Content
