DETAILED DESCRIPTION

[0028] The application will be further described in detail below with reference to the accompanying drawings.

[0029] The detection device for the underwater high-sealing safety valve disclosed by the application comprises a mounting part 1 arranged outside the safety valve and used for sealing treatment of the mounted valve. Figure 1 and Figure 2 The mounting part 1 comprises two mounting pieces 11, and the mounting part 1 is symmetrically arranged along a vertical plane where an axis of the pipeline is located. The two mounting pieces 11 are fixedly connected through a plurality of fasteners 16. The plurality of fasteners 16 are divided into two groups. The two groups of fasteners 16 are respectively arranged on upper and lower sides of the mounting piece 11. Each group of fasteners 16 comprises four fasteners 16, and the four fasteners 16 are symmetrically arranged along a vertical plane where a first opening 12 axis is located.

[0030] The mounting part 1 is provided with a cavity. An upper end of the mounting part 1 is provided with the first opening 12 for the rotating handle of the safety valve to pass out. In order to ensure positioning accuracy during installation of the mounting part 1, the first opening 12 is provided with an annular groove 121 for cooperation with the safety valve. The safety valve is clamped in the annular groove 121, thereby further enhancing sealing performance and installation stability of the mounting part 1. Second openings 13 for pipeline connection are arranged on both sides of the mounting part 1. The inner wall of the second opening 13 abuts against the outer wall of the pipeline. In order to enhance sealing effect of the second opening 13, the second opening 13 is provided with a rubber ring 131. The rubber ring 131 is sleeved on the pipeline. When the two mounting pieces 11 are close to each other, the second opening 13 drives the inner wall to abut against the outer wall of the pipeline.

[0031] As shown in Figure 1 and Figure 2 Due to large underwater pressure, in order to enhance service life of the mounting part 1, a plurality of annular support plates 15 for supporting the mounting part 1 are vertically arranged on the inner wall of the mounting part 1. The support plates 15 are arranged along an axis perpendicular to the pipeline. The side of the support plate 15 away from the mounting part 1 abuts against the outer wall of the pressure valve or the outer wall of the pipeline, thereby further enhancing support performance of the mounting part 1.

[0032] As shown in 2 and Figure 3 In order to realize the real-time detection of the leakage of the pressure valve, two third openings 14 are arranged on the side wall of the mounting part 1, and the third openings 14 are communicated with the cavity of the mounting part 1. A detection assembly 2 for detecting the third openings 14 is arranged on the inner wall of the mounting part 1, and the detection assembly 2 comprises a rotating plate 21 for closing the third openings 14, a torsion spring 22 for driving the rotating plate 21 to reset, and a detection part 23. One side of the rotating plate 21 is rotatably connected to the inner wall of the mounting part 1, and the two ends of the torsion spring 22 are fixedly connected to the rotating plate 21 and the mounting part 1, respectively. The one side of the mounting plate is abutted to the inner wall of the mounting part 1 by the torsion spring 22, so as to realize the closing of the third openings 14. The detection part 23 is fixedly arranged on the side edge of the rotating plate 21 away from the torsion spring 22. The rotating plate 21 drives the detection part 23 to abut to the inner wall of the mounting part 1, and when the rotating plate 21 rotates, the detection part 23 is driven to move away from the inner wall of the mounting part 1.

[0033] As shown in 1, in order to further monitor the water flow in the third openings 14, a flow detection meter 3 is arranged in the third openings 14, so as to realize the real-time detection of the water flow in the third openings 14, and facilitate the preliminary evaluation of the leakage of the safety valve by the staff. In order to ensure the accuracy of the detection of the leakage of the safety valve by the detection device, the third openings 14 are arranged in two, and the two third openings 14 are arranged on the two sides of the mounting part 1 along the pipeline axis.

[0034] The implementation principle of the embodiment is as follows:

[0035] First, the two mounting parts 11 are moved close to each other and mounted on the outside of the safety valve, and the two mounting parts 11 are fixed by the fasteners 16. When the safety valve leaks, the pressure in the mounting part 1 decreases, and the water flow on the outside of the mounting part 1 passes through the third openings 14, and the water flow drives the rotating plate 21 to rotate against the torsion spring 22, so as to make the detection part 23 move away from the inner wall of the mounting part 1.

[0036] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
