Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a valve tightness detection device comprises a shell 1, a circular hole 2 is arranged at the bottom of the shell 1, an internal thread ring 3 is fixedly arranged at the bottom of the shell 1, a thread matched with the internal thread ring 3 is arranged on the outer wall of a detected valve and used for fixing the whole device, a cover body 4 is fixedly arranged at the top of the shell 1, a sliding hole 5 is arranged in the middle of the cover body 4, an upright post 6 is slidably arranged on the inner side wall of the sliding hole 5, a circular plate 7 is fixedly arranged at the bottom end of the upright post 6, a spring 8 is fixedly arranged at the top of the circular plate 7, the state shown in figure 1 is in a normal state, the top end of the spring 8 is fixedly arranged at the bottom of the cover body 4, a sealing element 9 is fixedly arranged at the top of the circular plate 7, the sealing element 9 can prevent gas entering the shell 1 from escaping from the sliding hole 5, a moving, the bottom of the frame body 11 is fixedly provided with a fixed block 12.

Specifically, the sealing member 9 includes a rubber ring 13, an upper adhesive layer 14 and a lower adhesive layer 15 are fixedly mounted on both upper and lower ends of the rubber ring 13, the upper adhesive layer 14 and the lower adhesive layer 15 are respectively fixed on the bottom of the lid 4 and the top of the circular plate 7, and when the circular plate 7 moves upward, the up-and-down movement of the circular plate 7 can be adapted by the deformation force and the sealing effect of the rubber ring 13.
