[0022] 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.

[0023] Example 1

[0024] See also Figure 1-3 In the figure, a high-sealing regulating valve comprises a regulating valve body 1, a mounting box 3 is fixedly provided on the outer sides of the left and right ends of the regulating valve body 1, an adjusting block 5 is arranged inside the mounting box 3, a through hole 1 6 and a through hole 2 7 are provided on the right side of the adjusting block 5, the through hole 2 7 is located at the upper end of the through hole 1 6, a bearing seat 8 is fixedly provided on the upper end surface of the regulating block 5, a mounting seat 9 is fixedly provided on the upper end surface of the mounting box 3, a threaded groove 10 is provided on the upper end surface of the mounting seat 9, a threaded rod 11 is connected to the inner thread of the threaded groove 10, a rotating disk 12 is fixedly provided on the upper end surface of the threaded rod 11, the other end of the threaded rod 11 is installed inside the bearing seat 8, three mounting ring grooves 13 are provided on the outer side of the regulating block 5, and a sealing ring 14 is arranged inside the mounting ring groove 13.

[0025] See also Figure 2 The left and right sides of the installation box 3 are both provided with through grooves 4, and the through grooves 4 match the through hole 1 6 and the through hole 2 7.

[0026] In this embodiment, the through groove 4 is provided to facilitate the communication between the through hole 1 6 or the through hole 2 7 on the regulating block 5 and the pipeline on the regulating valve body 1 .

[0027] See also Figure 2 , the second through hole 7 is an L-shaped through hole.

[0028] In this embodiment, the second through hole 7 is provided to facilitate sealing of both sides of the valve core of the regulating valve body 1 when the valve core is damaged, thereby facilitating repairs by personnel.

[0029] Working principle: When in use, the personnel align the flange 2 on the regulating valve body 1 with the installation end of the main pipeline, and then use bolts to install the regulating valve body 1 on the main pipeline. At this time, the sealing ring 19 can seal the flange 2 and the installation end of the main pipeline. Then the personnel connect the bypass pipeline with the connecting pipe 20 through the flange 21, and a spare regulating valve is installed on the bypass pipeline; when the regulating valve body 1 is not damaged, the main pipeline can communicate with the valve core of the regulating valve body 1 through the through hole 6, so that the regulating valve body 1 can play a regulating role; when the regulating valve body 1 is damaged, the personnel rotate the rotating disks 12 on both sides, and the rotating disks 12 can drive the threaded rod 11 to rotate, and the threaded rod 11 can rotate. The rod 11 is acted upon by the threaded groove 10 on the mounting seat 9, thereby being able to drive the adjusting block 5 to move downward. In the process of the adjusting block 5 moving downward, the spring 15 is gradually compressed, and the rebound force of the spring 15 acts on the pressure sensor 17 through the pressure plate 16. The personnel can judge the position of the adjusting block 5 according to the pressure transmitted by the pressure sensor 17. When the pressure of the pressure sensor 17 reaches the specified value, the personnel can stop rotating the rotating disk 12. At this time, the through hole 27 is connected with the main pipeline and the bypass pipeline. The main pipeline can flow to the connecting pipe 20 and the bypass pipeline through the through hole 27, thereby avoiding the regulating valve body 1. At this time, the personnel can inspect and repair the regulating valve body 1 without stopping the machine, thereby ensuring production efficiency.

[0030] Example 2

[0032] In this embodiment: the model of the pressure sensor 17 is CYYZ11. When the adjusting block 5 is adjusted downward, the spring 15 is gradually compressed. The pressure sensor 17 senses the pressure of the spring 15 rebounding through the pressure plate 16. The personnel can adjust the adjusting block 5 according to the pressure. When the pressure reaches a predetermined value, the adjustment of the adjusting block 5 can be completed. At this time, the two ends of the through hole 2 7 are connected to the main and auxiliary pipelines.

[0033] See also Figure 1 A flange 2 is fixedly provided at the left and right ends of the regulating valve body 1.

[0034] In this embodiment, the flange 2 is provided to facilitate the connection between the regulating valve body 1 and the main pipe. By aligning the flange 2 with the installation end of the main pipe, personnel can use bolts to install the regulating valve body 1 and the main pipe.

[0035] See also Figure 1A mounting ring groove 2 18 is provided on the right side of the flange 2 , and a sealing ring 2 19 is provided inside the mounting ring groove 18 .

[0036] In this embodiment, the installation ring groove 18 is provided to facilitate the installation of the sealing ring 19. When the flange 2 is fixedly connected to the installation end of the main pipe, the sealing ring 19 can play a role in strengthening the seal, thereby avoiding leakage.

[0037] See also Figure 4 A connecting pipe 20 is provided on the back of the installation box 3, and a flange 21 is fixedly provided on the other end of the connecting pipe 20.

[0038] In this embodiment, the connecting pipe 20 matches the second through hole 7 , and after the second through hole 7 is adjusted to a specified position, the bypass pipeline and the connecting pipe 20 are connected to the main pipeline through the second through hole 7 .
