Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a hydraulically actuated actuator that is convenient to install, including a valve body 1 and a valve stem 2. A docking plate 3 is rotatably sleeved on the outer surface of the valve stem 2. The bottom end of the docking plate 3 is fixedly connected to the surface of the valve body 1. A hydraulically actuated actuator 5 is arranged above the valve body 1. A docking frame 7 is fixedly connected to the lower part of the hydraulically actuated actuator 5. A piston rod 6 is arranged below the hydraulically actuated actuator 5. The piston rod 6 is located inside the docking frame 7. A T-shaped docking block 9 is fixedly connected to the bottom end of the piston rod 6. A docking block 11 is fixedly connected to the top end of the valve stem 2. A groove 12 is formed inside the docking block 11. The inner wall of the groove 12 is slidably connected to the outer surface of the T-shaped docking block 9. A through groove 13 is formed on one side of the inner wall of the groove 12. A fixing component is arranged inside the through groove 13.

[0025] Further, the fixing component includes a clamping block 14. The outer surface of the clamping block 14 is slidably connected to the inner wall of the through groove 13. One end of the clamping block 14 is an inclined surface end and extends into the groove 12. A pull ring 18 is fixedly connected to one end of the clamping block 14. Limiting grooves 15 are opened on both sides of the inner wall of the through groove 13. Limiting blocks 16 are slidably connected to the inner walls of the two limiting grooves 15. The opposite ends of the two limiting blocks 16 are respectively fixedly connected to both sides of the clamping block 14. Pressure springs 17 are fixedly connected to one ends of the two limiting blocks 16. The ends of the two pressure springs 17 away from the corresponding limiting blocks 16 are respectively fixedly connected to the inner walls of the corresponding limiting grooves 15.

[0026] Further, a clamping groove 10 is opened on one side of the T-shaped docking block 9. The inner wall of the clamping groove 10 is in sliding contact with the inclined surface end of the clamping block 14. Four second threaded grooves 8 are opened inside the docking frame 7. Four first threaded grooves 4 are opened inside the docking disc 3. The inside of the four first threaded grooves 4 is adapted to the inside of the four second threaded grooves 8.

[0027] Further, when the staff installs the hydraulic actuator 5 on the valve body 1, then the docking frame 7 at the bottom of the hydraulic actuator 5 is located directly above the valve stem 2, and then the docking frame 7 is driven to move downward. Then the T-shaped docking block 9 moves downward at the same time. Then the T-shaped docking block 9 will fall into the groove 12. As the T-shaped docking block 9 slowly enters the groove 12, then the bottom end of the T-shaped docking block 9 contacts the inclined surface end of the clamping block 14, so as to squeeze and contact the inclined surface end of the clamping block 14. Then the clamping block 14 will be compressed and retracted into the through groove 13. When the T-shaped docking block 9 completely falls to the inner wall of the groove 12, under the action of the pressure spring 17, then the clamping block 14 will enter the clamping groove 10, so as to fix the T-shaped docking block 9 to the inner wall of the groove 12. At the same time, the bottom end of the docking frame 7 will fall onto the top end of the docking disc 3, and at the same time the first threaded groove 4 and the second threaded groove 8 are completely opposite, and then the adapted bolts can be used to connect and fix the inside of the first threaded groove 4 and the second threaded groove 8.

[0028] Further, through the fixing method of the T-shaped docking block 9 and the groove 12, the valve stem 2 and the piston rod 6 can be automatically connected after the hydraulic actuator 5 and the valve body 1 are installed. At the same time, with the clamping fixation of the clamping block 14 and the clamping groove 10, the T-shaped docking block 9 can be in a stable fixed state inside the groove 12, and the installation method is simple and fast, so that the staff can conveniently install the hydraulic actuator 5.

[0029] Further, through the arrangement of the limiting block 16 and the limiting groove 15, not only the clamping block 14 is limited in movement, but also the clamping block 14 slides more stably, and the T-shaped docking block 9 can be better fixed inside the groove 12.

[0030] Working principle: When the staff installs the hydraulic actuator 5 on the valve body 1, then the docking frame 7 at the bottom end of the hydraulic actuator 5 is located directly above the valve stem 2, and then the docking frame 7 is driven to move downward. Then the T-shaped docking block 9 also moves downward. Then the T-shaped docking block 9 will fall into the inside of the groove 12. As the T-shaped docking block 9 slowly enters the inside of the groove 12, then the bottom end of the T-shaped docking block 9 contacts the inclined surface end of the clamping block 14, so as to squeeze and contact the inclined surface end of the clamping block 14. Then the clamping block 14 will be compressed and retracted into the inside of the through groove 13. As the T-shaped docking block 9 completely falls to the inner wall of the groove 12, under the action of the compression spring 17, then the clamping block 14 will enter the inside of the card slot 10, so as to fix the T-shaped docking block 9 to the inner wall of the groove 12. At the same time, the bottom end of the docking frame 7 will fall onto the top end of the docking plate 3, and at the same time the first thread groove 4 and the second thread groove 8 are completely opposite. Then the adapted bolts can be used to connect and fix the inside of the first thread groove 4 and the second thread groove 8, so that the installation of the hydraulic actuator is completed.

[0031] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present utility model.
