[0020] When the connecting disk 6 needs to be disassembled, first pull the pull rod 81, and the movement of the pull rod 81 drives the first clamping plate 82 to move. When the first clamping plate 82 moves, it drives the buffer spring 85 to buffer. Then, when the first clamping plate 82 moves, it drives the sliding sleeve 86 to assist in moving on the surface of the sliding rod 87. At this time, the second clamping plate 83 is separated from the surface of the first clamping plate 82, and then the connecting disk 6 can be pulled out, so that the connecting disk 6 can be quickly and effectively disassembled.

[0027] The working principle of the bellows stop valve which is easy to disassemble and assemble provided by the utility model is as follows:

[0028] When in use, first rotate the rotating disk 3 to open the valve body 1 to allow the fluid to flow. Then, when the connecting disk 6 needs to be disassembled after a period of use, first pull the pull rod 81. The movement of the pull rod 81 drives the first clamping plate 82 to move. While the first clamping plate 82 moves, it drives the buffer spring 85 for buffering. Then, while the first clamping plate 82 moves, it drives the sliding sleeve 86 to assist in moving on the surface of the sliding rod 87. At this time, the second clamping plate 83 is separated from the surface of the first clamping plate 82, and then the connecting disk 6 can be pulled out, so that the connecting disk 6 can be quickly and effectively disassembled.
