Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: a valve for quick docking in chemical production, comprising a valve body 1 and a pipe 2, wherein the end of the pipe 2 is provided with a connecting flange 201, and the end of the valve body 1 is provided with a docking installation structure for quick docking with the pipe 2. The docking installation structure includes a connecting disc 3 provided at the end of the valve body 1, and a guide block 301 provided at the end of the connecting disc 3. A first sealing gasket 4 is provided on the inner wall of the connecting disc 3, and a protrusion 7 is provided on the outer wall of the connecting disc 3. A rotating block 701 is rotatably mounted at the end of the protrusion 7, and a fastening screw 702 is threadedly mounted at the end of the rotating block 701.

[0020] like Figures 1-5 As shown, the cross-section of the connecting plate 3 is U-shaped, and the end of the connecting plate 3 facing the connecting flange 201 is open. The connecting plate 3 is provided at both ends of the valve body 1. The guide blocks 301 are distributed at equal angles at the open end of the connecting plate 3, and the corners of the end of the guide blocks 301 are beveled. The outer wall of the connecting flange 201 is provided with positioning holes that are compatible with the guide blocks 301.

[0021] like Figures 1-4 As shown, the first sealing gasket 4 covers the inner wall of the connecting plate 3, and the end of the first sealing gasket 4 is designed at an angle. The inner wall of the first sealing gasket 4 is in contact with the side wall of the connecting flange 201. A second sealing gasket 5 is provided between the connecting flange 201 and the connecting plate 3. A sealing flange 501 is provided on the outer wall of the second sealing gasket 5. The sealing flange 501 is symmetrically arranged on both sides of the second sealing gasket 5. A sealing groove 6 that matches the sealing flange 501 is provided at the end of both the connecting flange 201 and the connecting plate 3.

[0022] like Figures 1-5 As shown, the protrusions 7 are distributed at equal angles on the outer wall of the connecting plate 3. The length of the rotating block 701 is less than the distance between the outer wall of the pipe 2 and the outer wall of the protrusion 7. The rotating block 701 has an L-shaped cross-section. The fastening screw 702 is perpendicular to the connecting flange 201. A fastening pressure block 704 is rotatably installed at the end of the fastening screw 702. The side of the fastening pressure block 704 away from the fastening screw 702 abuts against the outer wall of the connecting flange 201. A handle 703 is provided at the end of the fastening screw 702.

[0023] When installing the valve and pipe 2, first align the connecting flange 201 of one end of pipe 2 with the opening end of the U-shaped connecting disc 3 at the end of the valve body 1. Initial positioning is achieved using the guide blocks 301 evenly distributed at the opening end of the connecting disc 3. The angled design of the guide blocks 301 guides the connecting flange 201 to be smoothly inserted until the guide blocks 301 are fully engaged with the matching positioning holes on the outer wall of the connecting flange 201, completing the precise alignment of the valve and pipe 2 and avoiding the alignment problems encountered with traditional bolt connections. At this point, the first sealing gasket 4 on the inner wall of the connecting disc 3 will fit tightly against the side wall of the connecting flange 201, and simultaneously... The second sealing gasket 5 between the flange 201 and the end of the connecting plate 3 is inserted into the sealing groove 6 at both ends by the symmetrical sealing flanges 501 on both sides, forming a double seal. Then, the L-shaped rotating block 701 at the end of the protrusion 7 on the outer wall of the connecting plate 3 is rotated so that the fastening pressure block 704 at the end of the rotating block 701 is aligned with the connecting flange 201. The handle 703 at the end of the screw is rotated to drive the fastening screw 702 to be pushed along the thread until the fastening pressure block 704 at the end of the screw is tightly abutted against the outer wall of the connecting flange 201. The fastening operation can be completed by a single person without the need for multiple people to cooperate in bolt installation, achieving rapid docking.

[0025] When there are differences in the length of the pipes 2 being connected, the telescopic structure at the feed end of the valve body 1 can be adjusted to adapt to them. In the telescopic structure, the T-shaped telescopic inner tube 9, which is fixedly connected to the connecting plate 3, can slide along the inner wall of the U-shaped telescopic outer tube 8. The T-shaped cross-section of the telescopic inner tube 9 and the U-shaped cross-section of the telescopic outer tube 8 are matched to prevent them from separating during the sliding process, ensuring structural stability. When the telescopic inner tube 9 slides to adjust its length to adapt to the pipe 2, the T-shaped sealing ring 901 fitted at its end is always in close contact with the inner wall of the telescopic outer tube 8 to avoid media leakage in the telescopic gap and ensure sealing reliability.
