Water inlet groove 14 is in communication with the opening on the side, away from water inlet sleeve ring 12, of sealing rubber ring 13.

[0026] Further, the sealing rubber ring 13 has a diameter larger on the side close to the water inlet ring 12 than on the other side, facilitating water flow and making the sealing rubber ring 13 expand to adhere to the surface of the test pipeline 3.

[0027] Further, the closed cover pipe 2 is provided with pressure relief openings on both sides, which are in communication with the water inlet groove 14, facilitating water drainage when the closed cover pipe 2 is removed.

[0029] Further, the fixed pipe shell 6 is fixedly connected with the rotating ring 8 at the inner wall of the end away from the test pipeline 3, and the rotating ring 8 is rotatably connected to the surface of the water injection pipe head 5, facilitating the rotation of the fixed pipe shell 6 and reducing the deformation of the water outlet pipe of the pressure testing equipment main body 1.
