Description

Technical Field

[0001] The utility model relates to the field of pneumatic valve cylinder maintenance, in particular to a maintenance tooling for pneumatic valve cylinders. Background Technique

[0002] A pneumatic valve is a valve that uses compressed air as a power source. It controls the opening and closing of the valve through a pneumatic actuator. Pneumatic valves are widely used in industrial automation control systems, especially in occasions where remote control or frequent operation is required. A pneumatic valve cylinder is an actuator that uses compressed air as a power source and is widely used in various automation control and mechanical devices.

[0003] In existing industrial pipelines and process pipelines, various pneumatic valves need to be applied. For pneumatic valves with relatively frequent actions, it is necessary to regularly replace the valve sealing ring and the maintenance kit of the cylinder. However, there are currently no relevant tools or toolings for replacing the maintenance kit of pneumatic valve cylinders on the market. When performing maintenance, it is relatively difficult to replace the maintenance kit of the cylinder, thus affecting the maintenance efficiency.

[0004] Therefore, it is necessary to design a maintenance tooling for pneumatic valve cylinders that can install and disassemble this device, facilitate the replacement of the cylinder maintenance kit, and improve the maintenance efficiency. Content of the Utility Model

[0005] In order to overcome the shortcomings that there are currently no relevant tools or toolings for replacing the maintenance kit of pneumatic valve cylinders on the market, and it is relatively difficult to replace the maintenance kit of the cylinder during maintenance, thus affecting the maintenance efficiency, the utility model provides a maintenance tooling for pneumatic valve cylinders that can install and disassemble this device, facilitate the replacement of the cylinder maintenance kit, and improve the maintenance efficiency.

[0006] The technical solution is: a maintenance tooling for pneumatic valve cylinders, including a bottom plate, a connecting platform, fixing screws, a cover plate, welding nuts and ordinary nuts. The upper side of the middle part of the bottom plate is connected with a connecting platform. Four fixing screws are connected to the upper side of the bottom plate. A cover plate is sleeved between the upper parts of the fixing screws. A welding nut is connected to the upper side of the middle part of the cover plate. Ordinary nuts are threadedly connected to the fixing screws, and the ordinary nuts are all in contact with the cover plate.

[0007] Optionally, the connecting platform is conical.

[0008] Optionally, the ordinary nuts are all hexagonal.

[0009] Optionally, it further includes bolts, and bolts are threadedly connected to the welding nuts.

[0010] Optionally, the nuts of the bolts are hexagonal.

[0011] Optionally, a central hole is opened on the connecting platform.

[0012] The beneficial effects are as follows: 1. By loosening the ordinary nut of the present utility model, the ordinary nut is disengaged from the fixed screw rod, and then the bolt is rotated in the reverse direction to disengage the bolt from the welded nut. Then, the cover plate is removed, and then the bottom plate, the connecting table and the fixed screw rod are removed, so that the installation and disassembly of the device can be carried out, facilitating the replacement of the cylinder maintenance kit and improving the maintenance efficiency.

[0013] 2. By sleeving the cover plate on the fixed screw rod of the present utility model, the cover plate contacts the piston rod. Then, the ordinary nut contacts the fixed screw rod, and then the ordinary nut is rotated. Under the action of the thread, the ordinary nut moves downward to contact the cover plate, so that the clamp and the cover plate can be fixed, preventing the clamp and the cover plate from shifting during the installation process and causing damage to the piston or the inner wall of the cylinder, and improving the stability of using the device.

[0014] 3. By slowly moving the bolt downward, the piston rod, the piston ring and the sealing strip are moved downward into the cylinder sleeve, so that the piston rod, the piston ring and the sealing strip can be installed, preventing the sealing strip and the piston ring from not being fully clamped into the groove during installation or being extruded out of the groove during the process of entering the cylinder sleeve, resulting in damage to the sealing strip and the piston ring, improving the sealing effect of the piston and extending the service life of the cylinder.

[0018] The present utility model will be further described below in conjunction with the drawings and the specific embodiments.

[0019] A pneumatic valve cylinder maintenance tooling, as Figure 1 and Figure 2As shown in the figure, it includes a bottom plate 1, a connecting platform 2, fixing screws 3, a cover plate 4, welding nuts 5, ordinary nuts 6 and bolts 7. The upper side of the middle part of the bottom plate 1 is connected with the connecting platform 2. The connecting platform 2 is conical. Four fixing screws 3 are connected to the upper side of the bottom plate 1. A cover plate 4 is sleeved between the upper parts of the fixing screws 3. The upper side of the middle part of the cover plate 4 is connected with a welding nut 5. Ordinary nuts 6 are connected to the fixing screws 3 through threads. The ordinary nuts 6 are all in contact with the cover plate 4. The ordinary nuts 6 are all hexagonal. A bolt 7 is connected to the welding nut 5 through threads. The nut of the bolt 7 is hexagonal. A central hole 8 is opened on the connecting platform 2.

[0020] When maintenance is required for a pneumatic valve cylinder, this device can be used. Move this device to the place where maintenance of the pneumatic valve cylinder is needed. Sleeve the cylinder sleeve on this device so that the connecting platform 2 is aligned with the center of the cylinder sleeve. Then replace the piston rings and sealing strips on the piston. After replacement, tighten them with a clamp. Then insert the piston rod into the central hole 8 on the connecting platform 2. Then sleeve the cover plate 4 on the fixing screws 3 so that the cover plate 4 is in contact with the piston rod. Then pick up the ordinary nut 6 by hand so that the ordinary nut 6 is in contact with the fixing screw 3. Then turn the ordinary nut 6. Under the action of the thread, the ordinary nut 6 moves downward to contact the cover plate 4, so as to fix the clamp and the cover plate 4, preventing the clamp and the cover plate 4 from shifting during the installation process and causing damage to the piston or the inner wall of the cylinder, and improving the stability of using this device. Then pick up the bolt 7 so that the bolt 7 is in contact with the welding nut 5. Turn the bolt 7 by hand. Under the action of the thread, the bolt 7 slowly moves downward, and then the piston rod, piston rings and sealing strips move downward into the cylinder sleeve, so as to install the piston rod, piston rings and sealing strips, preventing the sealing strips and piston rings from not being fully clamped into the groove during installation or being extruded out of the groove during the process of entering the cylinder sleeve, causing damage to the sealing strips and piston rings, improving the sealing effect of the piston, and extending the service life of the cylinder. After the installation is completed, by loosening the ordinary nut 6, the ordinary nut 6 is disengaged from the fixing screw 3. Then turn the bolt 7 in the reverse direction so that the bolt 7 is disengaged from the welding nut 5. Then remove the cover plate 4, and then remove the bottom plate 1, connecting platform 2 and fixing screws 3, so as to install and disassemble this device, facilitating the replacement of the cylinder repair kit and improving the maintenance efficiency.
