The sliding column 18 is slidably connected to the inclined hole 14, and the sliding column 18 is used to drive the clamping block 9 to rise and fall. The high point of the inclined hole 14 is e, and the low point is f. When the push-pull rod 13 moves forward, the sliding column 18 is synchronously driven to move forward, so that the sliding column 18 slides on the inclined hole 14, and the sliding direction is toward e, which can drive the clamping block 9 to move downward, so as to facilitate the locking and fixing of the flange ring 8; when the push-pull rod 13 moves back, the sliding column 18 is synchronously driven to move back, so that the sliding column 18 slides on the inclined hole 14, and the sliding direction is toward f, which can drive the clamping block 9 to move upward, so that the clamping block 9 is separated from the flange ring 8, so as to loosen the flange ring 8. The push-pull rod 13 is used to drive the sliding column 18 to move, and the push-pull rod 13 matches the rectangular hole 10, and the spring 17 is used to drive the clamping block 9 to move in the direction close to the spring 17. The connecting pipe 2 is connected to a driving sleeve 5 for driving multiple push-pull rods 13 to move synchronously, and the driving sleeve 5 is connected to a locking mechanism for locking the driving sleeve 5.

[0030] The flange ring 8 at one end of the pipe 4 can be inserted into the connecting plate 3, that is, the flange ring 8 is connected to the connecting port 7, and then the driving sleeve 5 is pushed to move in the direction close to the connecting plate 3, thereby driving the multiple push-pull rods 13 to move forward, so that the sliding column 18 slides in the inclined hole 14, driving the corresponding clamping block 9 to move downward, and the inclined surface 15 and the inclined surface 2 16 slide relative to each other, exerting an inward thrust on the flange ring 8, and at this time, the spring 17 is gradually stretched.

The T-shaped column 6 passes through the guide block 21, and the T-shaped column 6 is fixedly connected to the guide block 21. The spring 19 is used to drive the guide block 21 to move toward the bottom direction of the T-shaped column 6. The connecting pipe 2 is provided with a slot 22 matching the bottom of the T-shaped column 6. When the drive sleeve 5 is not pushed forward, the bottom of the T-shaped column 6 is against the outer surface of the connecting tube 2. At this time, the spring 2 19 is in a compressed state. During the forward movement of the drive sleeve 5, the bottom of the T-shaped column 6 slides on the surface of the connecting tube 2 until the drive sleeve 5 is connected to the connecting plate 3. The bottom of the T-shaped column 6 is aligned with the slot 22. The spring 2 19 drives the guide block 21 to move downward, and simultaneously drives the T-shaped column 6 to move downward, so that the bottom of the T-shaped column 6 is inserted into the slot 22, thereby realizing the positioning and fixation of the drive sleeve 5. The operation is simple and flexible.

The spring groove 30 is connected with a spring three 29, and the end of the spring three 29 is connected with a sealing seat 28, and the sealing seat 28 is attached to the ball 27. The spring three 29 applies a thrust to the sealing seat 28, so that the sealing seat 28 and the ball 27 are sealed, and even if there is wear, it will automatically compensate to prevent leakage hazards.

[0039] Working principle: When connecting the pipeline 4, insert the flange ring 8 into the connecting plate 3 to connect the flange ring 8 with the connecting port 7. Then push the drive sleeve 5 forward, the drive sleeve 5 pushes the multiple push-pull rods 13 forward, and synchronously drives the slide column 18 forward, so that the slide column 18 slides on the inclined hole 14, and the sliding direction is toward e, and then drives the clamping block 9 to move downward, and the inclined surface 15 and the inclined surface 2 16 slide relative to each other, so that the flange ring 8 moves inward. When the drive sleeve 5 is connected to the connecting plate 3, the side of the clamping block 9 is connected to the flange ring 8, the spring 17 is in an elongated state, and the connecting surface 1 26 is pressed against the sealing surface 1 23, and the connecting surface 25 is pressed against the sealing surface 2 24, so as to achieve a good sealing effect, and also realize the rapid docking of the pipeline 4 and the valve body 1, shortening the installation time. The bottom of the T-shaped column 6 is aligned with the slot 22. The bottom of the T-shaped column 6 is inserted into the slot 22 through the cooperation of the spring 2 19, so that the drive sleeve 5 is locked and fixed, thereby preventing the clamping block 9 from moving, so that the valve body 1 and the pipeline 4 are firmly connected. When the pipeline 4 needs to be disassembled, the T-shaped column 6 is directly lifted to separate its bottom from the slot 22, so as to loosen the drive sleeve 5, and the drive sleeve 5 can be pulled back. The spring 17 applies an upward pulling force to the clamping block 9, so that pulling the drive sleeve 5 is more labor-saving, and the push-pull rod 13 drives the slide column 18 to move back, so that the slide column 18 moves toward the f direction, drives the clamping block 9 to move up and separate from the flange ring 8, so as to quickly loosen the flange ring 8, making the pipeline 4 flexible to disassemble and highly practical.
