The actuator 11 includes two oppositely arranged planes 113 and an arc surface 114. The planar protrusion 1432 and the arc-shaped hole wall 1431 of the connecting portion 143 are arranged corresponding to the plane 113 and the arc surface 114 of the actuator 11 to prevent the connecting portion 143 and the actuator 11 from rotating relative to each other.

[0056] The shaft sleeve 30 includes a shaft sleeve 31, and the shaft sleeve 31 includes a connecting portion 311 and a connecting portion 312 connected to each other. The connecting portion 312 is provided with a connecting groove 3121 for accommodating the valve stem 202. The connecting portion 312 is also provided with at least one through hole 3122 communicating with the connecting groove 3121, and at least one stopper 3123 extends into the through hole 3122 to stop the valve stem 202. When the thin valve stem 202 is accommodated in the connecting groove 3121, the stopper 3123 can be adjusted to screw forward into the connecting groove 3121 until it abuts against the valve stem 202, so that the valve stem 202 is stably accommodated in the connecting groove 3121; when the valve stem 202 of appropriate size is accommodated in the connecting groove 3121, the stopper 3123 may not be required. The connecting groove 3121 may be square, corresponding to the two planes 2021 of the valve stem 202, so as to drive the valve stem 202 to rotate.

[0057] The shaft sleeve 30 includes a shaft sleeve 32, and the shaft sleeve 32 includes a connecting portion 321 and a connecting portion 322 connected to each other. The connecting portion 322 is provided with a connecting groove 3221 for accommodating the valve stem 202. The connecting portion 322 is provided with at least one through hole 3222 communicating with the connecting groove 3221, and at least one stopper 3223 extends into the through hole 3222 to stop the valve stem 202. When the thin valve stem 202 is accommodated in the connecting groove 3221, the stopper 3223 can be adjusted to screw forward into the connecting groove 3221 until it abuts against the valve stem 202, so that the valve stem 202 is stably accommodated in the connecting groove 3221; when the valve stem 202 of appropriate size is accommodated in the connecting groove 3221, the stopper 3223 is not required. The height H of the connecting groove 3121 is lower than the height of the connecting groove 3221, and the width W of the connecting groove 3121 is greater than the width of the connecting groove 3221. The shaft sleeve 31 or the shaft sleeve 32 can be selected according to the size of the valve stem 202. The connecting groove 3221 can be square, corresponding to the two planes 2021 of the valve stem 202, so as to drive the valve stem 202 to rotate.

[0058] The shaft sleeve 30 further includes a shaft sleeve 33, and the shaft sleeve 33 includes a connecting portion 331, a connecting portion 332 connected to the connecting portion 331, and a cover plate 333. The connecting portion 332 is provided with a connecting groove 3321 for accommodating the valve stem 202. It can be understood that the connecting groove 3321 can also be formed by the connecting portion 332 and the cover plate 333. The connecting portion 332 is provided with at least one through hole 3322 communicating with the connecting groove 3321, the cover plate 333 is provided with at least one through hole 3331, and at least one stopper 3332 extends into the through hole 3322 and the through hole 3331 to stop the valve stem 202. When the thinner valve stem 202 is accommodated in the connection groove 3321, the adjustable stopper 3332 can be screwed forward into the connection groove 3321 to adjust the distance between the cover plate 333 and the bottom wall 3323, and the cover plate 333 can stably accommodate the valve stem 202 in the connection groove 3321. When the valve stem 202 of appropriate size is accommodated in the connection groove 3321, the stopper 3332 is also required to stably connect the cover plate 333 and the bottom wall 3323. The height H of the connection groove 3121 can be lower than the height of the connection groove 3321, and the width W of the connection groove 3121 is greater than the width of the connection groove 3321. The height of the connection groove 3221 can be lower than the height of the connection groove 3321, and the width of the connection groove 3221 is less than the width of the connection groove 3321. The shaft sleeve 31, shaft sleeve 32 or shaft sleeve 33 can be selected according to the size of the valve stem 202. The connecting groove 3321 may be square and correspond to the two planes 2021 of the valve stem 202 to drive the valve stem 202 to rotate.

[0059] The suitable shaft sleeve 30 can be adjusted and selected to be connected with valve stems 202 of different sizes, so that the actuator 10 can open and close valves 201 of different sizes, and has better versatility.

[0060] The bracket assembly 50 includes a transverse bracket 51, two longitudinal brackets 52, two clamps 53, and two washers 54. Each longitudinal bracket 52 is connected to a corresponding connecting portion 512, and each clamp 53 connects a corresponding longitudinal bracket 52 to one end of the pipeline 200. Compared with the solution in the prior art that only one connecting member is connected to the pipeline 200, the present invention uses two clamps 53 and two longitudinal brackets 52 to connect to the pipeline 200, which are respectively located on both sides of the valve 201, so as to avoid deformation of the pipeline 200 during operation. A through hole 511 is provided at the approximate middle position of the transverse bracket 51, and the shaft sleeve 30 passes through the through hole 511 and is connected to the actuator 11. The two longitudinal brackets 52 are located at both ends of the transverse bracket 51, and the two longitudinal brackets 52 are arranged approximately perpendicular to the transverse bracket 51. Each connecting portion 512 is provided with a long hole 5121 extending in the transverse direction.

[0061] The longitudinal bracket 52 includes two connecting plates 521 arranged opposite to each other, and a gap 5211 is formed between the two connecting plates 521. The connecting plates 521 are also provided with a plurality of through holes 5213. The connecting portion 512 can be accommodated in the gap 5211. The fixing member 5212 such as a screw can pass through the through hole 5213 and the long hole 5121 to stably connect the connecting plate 521 and the connecting portion 512. The position of the connecting plate 521 in the long hole 5121 is movable. When it is moved to a suitable position, the position of the connecting plate 521 can be fixed by the fixing member 5212 and a nut. The washer 54 is also located in the gap 5211 and is arranged near the lower end of the connecting plate 521. The washer 54 is provided with two through holes (not shown) arranged at intervals. The fixing member 5212 can pass through the through hole 5213 and the through hole of the washer 54 to connect the washer 54 to the connecting plate 521.

[0062] The lower end of the connecting plate 521 has an inclined portion 522, and a through hole 5221 is formed on the inclined portion 522. The clamp 53 can pass through the through hole 5221 and be wrapped around the pipeline 200 to connect the longitudinal bracket 52 with the pipeline 200. The inclined portion 522 can be set on the pipeline 200. The size of the clamp 53 is adjustable, and can be adjusted by the adjustment portion 531. The through hole 5221 can be formed on the inclined portion 522, or on the straight plate of the inclined portion 522 and the connecting plate 521. When the clamp 53 is tightened, the connecting plate 521 will be squeezed, and the washer 54 can prevent the connecting plate 521 from being squeezed too much.

[0063] The connection hole 1421 of the connection part 142 may be square, preferably square, and the connection part 311 / 321 / 331 of the sleeve 30 may also be square, preferably square, and the four corners of the square connection part 311 / 321 / 331 may be arc-shaped, so that the connection part 311 / 321 / 331 can be inserted into the connection hole 1421 of the connection part 142. The connection part 311 / 321 / 331 can be accommodated in the connection hole 1421 in an adaptive manner, or accommodated in the connection hole 1421 in an interference manner, so that the connection part 311 / 321 / 331 can be movably accommodated in the connection hole 1421, that is, the connection part 311 / 321 / 331 can be accommodated in the connection hole 1421 in a telescopic manner. When the diameter of the pipeline 200 is large, after the clamp 53 is connected to the pipeline 200, the distance between the valve stem 202 and the actuator 21 is relatively close, so that the connecting part 311 / 321 / 331 can be further extended into the connecting hole 1421, ensuring that the valve stem 201 can be stably connected to the actuator 21 through the shaft sleeve 30; when the diameter of the pipeline 200 is small, after the clamp 53 is connected to the pipeline 200, the distance between the valve stem 202 and the actuator 21 is relatively far, so that the connecting part 311 / 321 / 331 can be further extended from the connecting hole 1421 (very small part is accommodated in the connecting hole 1421), ensuring that the valve stem 201 can be stably connected to the actuator 21 through the shaft sleeve 30.

[0064] The actuator 10 can be controlled by an external controller component to open and close the valve 202, and a battery can be provided in the external control component to provide power for the actuator 10. A controller 40 connected to the external controller component can also be provided in the housing 101 of the actuator 10, and a valve-controlled switch can be provided on the controller 40. When the external controller component issues an opening or closing instruction to the valve-controlled switch, the actuator 10 can drive the valve stem 202 to rotate forward or reversely through the actuator 11, thereby opening or closing the valve stem 202. Two in-position indicators 41 can be provided on the controller 40, which are respectively used to indicate whether the valve stem 202 has rotated to the in-position (whether it has rotated to the opening position and the closing position), and feedback to the controller 40 and the external controller component so that the actuator 11 stops driving the valve stem 202 to rotate. The controller 40 is provided with a through hole 42, and the actuator 11 can pass through the through hole 42 to connect with the operating member 60. When the valve 202 is not opened or closed by an external controller component, when the clutch 80 is pressed, the clutch lifts one of the transmission gears and moves it upward, so that the transmission gear connected to the actuator 11 is not connected to the transmission gear connected to the drive member 12. At this time, the operating member 60 can be rotated to manually open or close the valve stem 202; when the valve 202 needs to be opened or closed by an external controller component, when the clutch 80 is pressed again, one of the transmission gears moves downward, so that the transmission gear connected to the actuator 11 is connected to the transmission gear connected to the drive member 12.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
