[0002] The antibiotic shut-off valve is a specialized shut-off valve designed for high-hygiene-requirement fields such as bio-fermentation and pharmaceutical manufacturing. It is primarily used to control the flow of sterile media such as antibiotics, preventing product contamination. ； The pneumatic actuator of the antibiotic shut-off valve refers to a drive device that uses clean compressed air as a power source to convert air pressure energy into mechanical linear thrust, driving the valve stem and valve disc of the antibiotic shut-off valve to move up and down, thereby realizing the opening and closing or switching control of the valve.

[0003] However, the existing pneumatic actuators of antibiotic shut-off valves are generally fixed to the two side sealing shells on their outer surface by multiple bolts. When the internal structure of this device malfunctions and needs to be repositioned, the operation of removing the side sealing shells is cumbersome and affects the maintenance efficiency of the device. Therefore, it does not meet the existing requirements. In response, we have proposed a pneumatic actuator for antibiotic shut-off valves. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The pneumatic actuator body 1 (model GT52), magnetic buckle 11 (model MAG) and spring 15 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4The present invention provides an embodiment of an antibiotic shut-off valve pneumatic actuator, comprising a pneumatic actuator body 1, a fixing head 3 fixed on both sides of the front and rear end faces of the pneumatic actuator body 1, a fixing spring 4 provided inside the fixing head 3, a rectangular fixing head 5 extending to the outside of the fixing head 3 connected to one end of the fixing spring 4, and the front end face of the rectangular fixing head 5 located in front of the pneumatic actuator body 1 and the rear end face of the rectangular fixing head 5 located behind the pneumatic actuator body 1 are both inclined surfaces 6; The pneumatic actuator body 1 has a side shell 2 on both the front and rear sides. A connecting groove 7 is provided on the outer surface of the side shell 2 corresponding to the fixed head 3. A slot 8 is provided on one side of the inner wall of the connecting groove 7. The fixed head 3 is inserted into the connecting groove 7, and a rectangular fixed head 5 extending to the outside of the fixed head 3 is inserted into the slot 8. A push plate 9 is provided on one side of the rectangular fixed head 5, which is slidably connected to the side shell 2. A push ring 10 is fixed to the front end face of the two push plates 9 located in front of the pneumatic actuator body 1 and the rear end face of the two push plates 9 located behind the pneumatic actuator body 1. When it is necessary to move the side shell... 2 When fixed on the outer surface of the pneumatic actuator body 1, the two connecting grooves 7 on the outer surface of the side shell 2 are respectively aligned with the two connecting grooves 7 on the front or rear face of the pneumatic actuator body 1, and pushed towards the pneumatic actuator body 1. As the side shell 2 gradually approaches the pneumatic actuator body 1, the inclined surface 6 on the outer surface of the rectangular fixed head 5 located outside the fixed head 3 will contact the entrance of the connecting groove 7. Under the action of the inclined surface 6, as the fixed head 3 gradually goes deeper, the rectangular fixed head 5 will be gradually pushed into the interior of the fixed head 3 and squeeze the fixed spring 4 connected to it. Once the fixing head 3 is fully inserted into the connecting groove 7, the rectangular fixing head 5 can be snapped into the slot 8 inside the side shell 2 by the reaction force of the compressed fixing spring 4, thereby fixing the side shell 2.

[0018] The face of the push plate 9 facing the fixed head 3 is in contact with the fixed head 3, and the top end of the push plate 9 corresponds to the inclined surface 6 on the outer surface of the rectangular fixed head 5. When it is necessary to remove the side shell 2 and open the internal structure of the pneumatic actuator body 1 for maintenance, push the push ring 10 towards the pneumatic actuator body 1. As the push ring 10 moves, the two push plates 9 fixed to it will move together. As the push plate 9 moves, the push plate 9 will contact the inclined surface 6 on the outer surface of the rectangular fixed head 5. As the push plate 9 continues to move, the rectangular fixed head 5 will be gradually pushed into the interior of the fixed head 3 again. When the rectangular fixed head 5 is completely removed from the interior of the slot 8, the fixation between the pneumatic actuator body 1 and the side shell 2 will also be released, and then the side shell 2 can be removed directly. The above technical solution enables quick disassembly and assembly of the side housing 2. When it is necessary to open the internal structure of the pneumatic actuator body 1 for maintenance, simply push the push ring 10 first, and then the side housing 2 can be removed to open the internal structure of the pneumatic actuator body 1, thereby improving the maintenance efficiency of the equipment.

[0019] The push plate 9 has a cylindrical groove facing the pneumatic actuator body 1. A metal column fixed to the inside of the side shell 2 is movably inserted inside the cylindrical groove. A spring 15 is sleeved on the outer surface of the metal column, and the two ends of the spring 15 are connected to the push plate 9 and the side shell 2 respectively. Through the spring force of the spring 15 connected to the push plate 9, the push ring 10 and the push plate 9 can be supported and positioned in the current position without being pushed by the push ring 10.

[0020] A magnetic buckle 11 is provided on both sides of the push ring 10. A strip-shaped groove 12 is provided on the outer surface of the magnetic buckle 11 at the position corresponding to the push ring 10, and the magnetic buckle 11 is made of a single magnet. A fixing groove 13 is provided on one side of the magnetic buckle 11 on the outer surface of the pneumatic actuator body 1. The shape of the end of the outer surface of the magnetic buckle 11 without the strip-shaped groove 12 corresponds to the inner wall shape of the fixing groove 13, and a square iron plate 14 is fixed inside the fixing groove 13 at the position corresponding to the magnetic buckle 11. Before normal use of the equipment, the strip-shaped groove 12 is... Align the push ring 10, and then move the magnetic buckle 11 toward the square shape of the pneumatic actuator body 1. As the magnetic buckle 11 moves gradually, the strip groove 12 on the outer surface of the magnetic buckle 11 will gradually lock onto the outside of the push ring 10. As the moving distance of the magnetic buckle 11 increases, the end of the magnetic buckle 11 without the strip groove 12 will lock into the inside of the fixing groove 13 on the outer surface of the pneumatic actuator body 1, and fix the magnetic buckle 11 to the outer surface of the square iron plate 14 by its own magnetic force, thereby fixing the magnetic buckle 11. The magnetic buckle 11, which is fixed to the outer surface of the push ring 10 by the strip slot 12 in the above technical solution, can fix the push ring 10. This structure can prevent the push ring 10 from being pushed accidentally, thereby preventing the internal structure of the pneumatic actuator body 1 from being opened.

[0021] A sealing ring is provided between the two fixing heads 3 fixed to the front end face of the pneumatic actuator body 1 and the two fixing heads 3 fixed to the rear end face of the pneumatic actuator body 1. A sealing groove is provided on the outer side of the sealing ring located on the outer surface of the side housing 2, and the outer surface of the sealing ring is in contact with the inner wall of the sealing groove. The sealing ring and sealing groove can increase the sealing between the pneumatic actuator body 1 and the side housing 2, thereby preventing leakage of the equipment during normal use.

[0022] The bottom end of the rectangular fixing head 5 is fixed with a square anti-detachment plate located inside the fixing head 3. The outer side of the square anti-detachment plate is provided with an anti-detachment groove located inside the fixing head 3. This structure can prevent the rectangular fixing head 5 from falling off the fixing head 3.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
