Precautions for disassembly and installation of pneumatic valve cylinder

The cylinder of the pneumatic valve mainly provides gas power for the operation of the valve. What aspects should be paid attention to in disassembly and installation?

First, we need to disassemble the cylinder from the valve body. Starting from the cover of the two ports of the cylinder, completely disassemble the cover. When disassembling the piston, pay special attention to the direction of the gear bar, and then forcefully transfer the cylinder shaft in a clockwise direction. Make the piston move quickly to the outermost.

Close the valve hole and gradually ventilate, and then use a larger air pressure to completely push out the internal piston. In this method, you must pay attention to gradually ventilate the pneumatic valve, otherwise the piston will suddenly spray out. This situation is very dangerous. It may cause injury to the operator. Completely remove the stuck spring on the cylinder shaft. Then take out the cylinder shaft from the other end of the valve. After the above preparations are done, all the parts inside the valve can be cleaned collectively, and lubricating grease needs to be added to the parts. The key parts for adding lubrication are: the inner cavity wall of the cylinder, the piston sealing circle, the gear bar and the back ring sheet. The gear shaft and the sealing circle also need to add a certain amount of butter.

After adding grease to the pneumatic valve, you need to install it in the order of disassembly and the components in the reverse order. There are some items that need special attention during installation. Be sure to pay attention to the assembly position of the gear bar to ensure that the piston can move quickly when the cylinder is ventilated. To the innermost position of the cylinder.

After the piston is fully retracted, it is necessary to keep the top notch of the gear shaft and the cylinder body in a horizontal direction. When the pneumatic valve is closed, the piston moves to the outermost position. At this time, the upper notch of the gear shaft is perpendicular to the cylinder body. The order and position of installing the valves must be clarified, and the installation drawings must be understood before the specific assembly. Prepare the parts that need to be assembled in advance, check the parts first to see if there are missing parts, place the parts on the work surface in a certain order, make sure that each part is in the proper position when assembling, and the direction of the part is also required Keep it right.
