[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a valve sealing detection device, including a mounting seat 1, a bracket 2, a bidirectional threaded rod 3, a sleeve 4, a motor 5, a support frame 6, a positioning cylinder 7, a threaded rod 8, a spring 9, a detection plate 10, a clamping arm 11, a support platform 12, an injection platform 13, a ventilation pipe 14, an electric telescopic rod 15 and a vacuum pump 16.

[0025] The bidirectional threaded rod 3 passes through the inside of the bracket 2, the outer side of the bidirectional threaded rod 3 is sleeved with a sleeve 4, and the left end of the sleeve 4 is installed with a motor 5, the upper end of the sleeve 4 is connected to a support frame 6, and the outer end of the support frame 6 is installed with a positioning cylinder 7, and the interior of the positioning cylinder 7 is installed with a threaded rod 8, the outer side of the right end of the threaded rod 8 is sleeved with a spring 9, and the inner end of the spring 9 is provided with a detection plate 10, and the inner end of the detection plate 10 is installed with a clamp arm 11;

[0027] like Figure 1 and Figure 4As shown, the bidirectional threaded rod 3 passes through the interior of the bracket 2, and the sleeve 4 is sleeved on the outer end of the bidirectional threaded rod 3, and the inner end of the sleeve 4 is connected to the bidirectional threaded rod 3 by means of threads, and the threads at the left and right ends of the bidirectional threaded rod 3 are arranged in opposite directions, and the sleeve 4 is symmetrically arranged about the central axis of the bidirectional threaded rod 3. When using the valve detection device, first place the valve to be detected on the upper surface of the support platform 12, and then start the motor 5, so that the right end of the motor 5 drives the bidirectional threaded rod 3 to rotate clockwise. Due to the different arrangement of the threads on the surface of the bidirectional threaded rod 3, the sleeves 4 at the left and right ends of the bidirectional threaded rod 3 move towards each other, and both approach the inside to squeeze and limit the valve wall, thereby clamping the valve, which is convenient for avoiding valve displacement during the subsequent inflation of the valve.

The clamp arm 11 is symmetrically arranged about the central axis of the injection platform 13, and a circular semi-slot hole that fits the valve wall is opened in the middle of the clamp arm 11. When the clamp arm 11 clamps the device, the threaded rod 8 can be rotated to rotate the interior of the threaded rod 8, thereby fine-tuning the position of the valve, so that the lower end of the two-way threaded rod 3 is aligned with the upper mouth of the valve, which improves the detection accuracy of the device, prevents gas leakage, and improves the sealing of the entire device. When the clamp arm 11 clamps the valve, the electric telescopic rod 15 is started and moved downward, so that the injection platform 13 is buckled at the upper end of the valve, and then the vacuum pump 16 is started to inflate the interior of the vent pipe 14 and inject it into the interior of the valve through the injection platform 13. The air leakage on the side of the valve is detected by the detection plate 10, which is convenient for evaluating the air tightness of the valve, judging whether there is air leakage, and the detection result is accurate.
