Purchasing pneumatic valves only requires specifying the specifications, type, and operating pressure, which meets the procurement requirements. They can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. However, existing pneumatic valve actuators are not convenient for quick disassembly and secure installation of the drive lugs, thus affecting assembly and disassembly efficiency.

[0003] To solve the above problems, a pneumatic valve drive device is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic valve drive device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic valve driving device, including a pneumatic box, an air pump fixedly installed at the top of the inner side of the pneumatic box, a movable plate slidably installed in the middle of the inner side of the pneumatic box, a sealing ring fixedly installed at the connection between the movable plate and the pneumatic box, an air pump fixedly installed in the middle of the top of the pneumatic box, an air outlet pipe fixedly connected to the air outlet end of the air pump, the bottom end of the air outlet pipe passing through the sealing plate and correspondingly installed with the movable plate, reset springs fixedly installed at the bottom of both sides of the inner wall of the pneumatic box, a connecting seat fixedly installed in the middle of the bottom end of the movable plate, a connecting block engaged at the bottom end of the connecting seat, and a driving protrusion fixedly connected to the bottom end of the connecting block.

[0006] The limiting engagement between the connecting groove and the connecting block, and the limiting engagement between the fixing pin and the fixing groove, facilitates the initial positioning of the drive protrusion. The two fixing bolts, which are respectively fixed to the threads of the two threaded holes, facilitate further positioning and fixation of the drive protrusion, thereby ensuring the stable operation of the drive protrusion. By loosening the two fixing bolts, the drive protrusion is separated from the two threaded holes, and the connecting block is no longer fixed. Then, by applying a larger force to pull the drive protrusion downward, the fixing pin is separated from the fixing groove, which facilitates the quick disassembly and replacement of the drive protrusion. Preferably, both reset springs are configured to correspond to the movable plate.

[0007] Preferably, the bottom of both sides of the connecting block is provided with a fixing bolt threaded on it, and both sides of the connecting block are provided with threaded holes, and the two fixing bolts are respectively threaded to the two threaded holes.

[0008] Preferably, a connecting groove is provided at the connection between the connecting seat and the connecting block, and the connecting groove is engaged with the connecting block.

[0009] Preferably, a fixing slot is provided at the connection between the connecting block and the connecting groove, and a fixing post is fixedly provided at the connection between the connecting groove and the connecting block, and the fixing post is engaged with the fixing slot.

[0011] Preferably, the air pump has an air inlet pipe fixedly connected to its air inlet end, and the top end of the air inlet pipe extends to the outside and is fixedly connected to a filter.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: High-pressure gas is delivered to the space between the sealing plate and the moving plate through the air outlet pipe by an air pump, thereby pushing the moving plate and other structures to move downward, which in turn pushes the driving protrusion downward, thus opening the valve. The up-and-down movement of the driving protrusion is converted into the opening and closing action of the valve. The limiting engagement between the connecting groove and the connecting block and the limiting engagement between the fixed pin and the fixed slot facilitates the initial limiting of the driving protrusion. The two fixing bolts are respectively fixed to the threads of the two threaded holes to facilitate the further limiting and fixing of the driving protrusion, thereby ensuring the stable operation of the driving protrusion. By loosening the two fixing bolts, the connecting block is no longer fixed. Then, a larger force is used to pull the driving protrusion downward, causing the fixed pin to separate from the fixed slot, thus facilitating the quick disassembly and replacement of the driving protrusion.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0016] Please see Figure 1-4 This utility model provides a pneumatic valve driving device, including a pneumatic box 1. An air pump 2 is fixedly installed on the top of the inner side of the pneumatic box 1. A movable plate 5 is slidably installed in the middle of the inner side of the pneumatic box 1. A sealing ring 6 is fixedly installed at the connection between the movable plate 5 and the pneumatic box 1. The air pump 2 is fixedly installed in the middle of the top of the pneumatic box 1. An air outlet pipe 4 is fixedly connected to the air outlet end of the air pump 2. The bottom end of the air outlet pipe 4 passes through the sealing plate 3 and is correspondingly installed with the movable plate 5. Reset springs 7 are fixedly installed on the bottom of both sides of the inner wall of the pneumatic box 1. A connecting seat 8 is fixedly installed in the middle of the bottom end of the movable plate 5. A connecting block 9 is engaged at the bottom end of the connecting seat 8. A driving protrusion 10 is fixedly connected to the bottom end of the connecting block 9. Two reset springs 7 are correspondingly installed with the movable plate 5. Fixing bolts 11 are threadedly installed on the bottom of both sides of the connecting block 9. Threaded holes 12 are opened on both sides of the connecting block 9. The two fixing bolts 11 are threadedly connected to the two threaded holes 12 respectively. High-pressure gas is delivered through the air pump 2 to the space between the sealing plate 3 and the moving plate 5 via the air outlet pipe 4. This pushes the moving plate 5 and other structures downward, thereby pushing the drive protrusion 10 downward and opening the valve. The up-and-down movement of the drive protrusion 10 is converted into the opening and closing action of the valve. The limiting engagement between the connecting groove 14 and the connecting block 9, and the limiting engagement between the fixing pin 15 and the fixing groove 13, facilitate the initial limiting of the drive protrusion 10. The two fixing bolts 11 are respectively fixed to the threads of the two threaded holes 12 to further limit and fix the drive protrusion 10, thereby ensuring the stable operation of the drive protrusion 10. By loosening the two fixing bolts 11, the drive protrusion 10 is separated from the two threaded holes 12, and the connecting block 9 is no longer fixed. Then, a larger force is used to pull the drive protrusion 10 downward, causing the fixing pin 15 to separate from the fixing groove 13, thus facilitating the quick disassembly and replacement of the drive protrusion 10.

[0017] In this embodiment, the pneumatic box 1 serves as the main frame of the entire device. It is made of high-strength, corrosion-resistant metal materials, such as stainless steel or aluminum alloy, to ensure good structural integrity and sealing under various harsh working environments. Its interior is rationally divided into different functional areas, providing stable space for the installation and operation of various components. The air pump 2 is the power core of the device, fixedly installed on the top of the inner side of the pneumatic box 1. It employs advanced air compression technology to quickly and stably compress outside air into high-pressure gas, which is then delivered to the outlet pipe 4 through the outlet end. The air pump 2 features high efficiency, energy saving, low noise, and stable operation. Its output pressure and flow rate can be precisely adjusted according to the actual working requirements of the valve. The reset spring 7 is made of a highly elastic metal material, such as spring steel. Its function is to push the valve open after the moving plate compresses the gas during downward movement, and when the air pump 2 stops supplying air, it uses its own elastic force to push the moving plate back to its initial position, thus automatically closing the valve. The design of the reset spring 7 has been precisely calculated and optimized to provide a stable and reliable reset force, ensuring accurate valve reset under various working conditions. Example 2

[0018] Please see Figure 1-4This utility model provides a pneumatic valve driving device, including a pneumatic box 1. An air pump 2 is fixedly installed on the top of the inner side of the pneumatic box 1. A movable plate 5 is slidably installed in the middle of the inner side of the pneumatic box 1. A sealing ring 6 is fixedly installed at the connection between the movable plate 5 and the pneumatic box 1. The air pump 2 is fixedly installed in the middle of the top of the pneumatic box 1. An air outlet pipe 4 is fixedly connected to the air outlet end of the air pump 2. The bottom end of the air outlet pipe 4 passes through the sealing plate 3 and is correspondingly installed with the movable plate 5. The bottom of both sides of the inner wall of the pneumatic box 1 is fixed. A reset spring 7 is provided. A connecting seat 8 is fixedly provided at the middle of the bottom of the moving plate 5. A connecting block 9 is engaged at the bottom of the connecting seat 8. A driving protrusion 10 is fixedly connected to the bottom of the connecting block 9.

A fixing groove 13 is provided at the connection between the connecting block 9 and the connecting groove 14. A fixing post 15 is fixedly provided at the connection between the connecting groove 14 and the connecting block 9. The valve is connected to the fixed slot 13. High-pressure gas is delivered through the air pump 2 to the space between the sealing plate 3 and the moving plate 5 via the air outlet pipe 4. This pushes the moving plate 5 and other structures downward, thereby pushing the drive protrusion 10 downward and opening the valve. The up-and-down movement of the drive protrusion 10 is converted into the opening and closing action of the valve. The connection slot 14 and the connecting block 9 are engaged to limit the connection, and the fixed pin 15 and the fixed slot 13 are engaged to limit the connection. The two fixing bolts 11 are fixed to the threads of the two threaded holes 12 to further limit and fix the drive protrusion 10, thereby ensuring the stable operation of the drive protrusion 10. By loosening the two fixing bolts 11, the connection block 9 is no longer fixed. Then, the drive protrusion 10 is pulled downward with a larger force to separate the fixed pin 15 from the fixed slot 13, thus facilitating the quick disassembly and replacement of the drive protrusion 10.

[0019] In this embodiment, by setting a sealing ring 6 at the connection between the moving plate 5 and the pneumatic box 1, employing multiple sealing measures between the air outlet pipe 4 and the sealing plate 3, and using a snap-fit ​​connection design for the connecting components, gas leakage can be effectively prevented, ensuring the efficient operation of the pneumatic drive system 1. The excellent sealing performance not only improves energy utilization but also reduces potential safety hazards caused by gas leakage. The various components of the device are rationally designed, possessing a certain degree of versatility and adjustability. The output pressure and flow rate of the air pump 2 can be adjusted according to the actual working requirements of the valve, and the elastic force of the reset spring 7 can also be changed by replacing springs of different specifications. This adaptability allows the device to be widely used in various types of valves and industrial scenarios. The design of the drive protrusion 10 is customized according to the valve's drive requirements, enabling precise cooperation with the valve's drive components to convert the up-and-down movement of the moving plate 5 into the opening and closing actions of the valve.

The up-and-down movement of the drive protrusion 10 is converted into the opening and closing action of the valve. The limiting engagement between the connecting groove 14 and the connecting block 9 and the limiting engagement between the fixing pin 15 and the fixing groove 13 facilitates the initial limiting of the drive protrusion 10. The two fixing bolts 11 are respectively fixed to the threads of the two threaded holes 12 to further limit and fix the drive protrusion 10, thereby ensuring the stable operation of the drive protrusion 10. By loosening the two fixing bolts 11, the drive protrusion 10 is separated from the two threaded holes 12, and the connecting block 9 is no longer fixed.
