[0031] It should be noted that the contraction body 10 is sleeved inside the connection port 2, and its aperture size is consistent with that of the connection port 2 to ensure a good sealing effect.
[0032] In some embodiments, the side end face of the abutting body 9 is closely attached to the outer end face of the connection port 2. The front clamping body 8 is integrally connected to the outside of the abutting body 9. The front clamping body 8 and the abutting body 9 are fixedly provided with a docking hole 13, and the aperture size of the docking hole 13 is consistent with that of the fixing hole 5.
[0033] It should be noted that the side end face of the abutting body 9 is closely attached to the outer end face of the connection port 2, and the front clamping body 8 is integrally connected to the outside thereof.

The shrinkage body 10 inside it is made of elastic rubber material, which can closely fit the inner wall of the connecting port to form the first layer of seal. At the same time, the abutting body 9 closely adheres to the outer end face of the connecting port 2, and the front clamping body 8 covers it to form the second layer of seal. The combined action of these two sealing structures ensures zero leakage at the connection between the valve and the pipeline. The elastic characteristics of the shrinkage body 10 enable it to adapt to minor deformations of the pipeline, while the hard rubber materials of the front clamping body 8 and the abutting body 9 provide additional structural support to prevent the sealing ring from deforming under high-pressure environments, thus maintaining a long-term stable sealing effect. Multiple groups of fixing holes 5 are arranged outside the connecting port 2 and are matched with the docking holes 13 on the connecting part. The valve body 1 is fixedly connected to the external pipeline by passing fixing bolts through these holes, ensuring the stability and reliability of the connection. The socket body 11 is fixedly clamped inside the valve body 1, and its external clamping port 12 allows for position adjustment within a certain range. This design enables even in the case of slight misalignment in the pipeline system, the connection between the valve and the pipeline can be optimized by finely adjusting the clamping port 12, reducing stress concentration and extending the service life.
