There is no need to rotate it multiple times like bolts are tightened to achieve the tightening effect, and professional tools are required to rotate the inner shaft 35. The safety of installation and disassembly is improved to a certain extent. When the regulating valve body 1 after the fixing is completed is used, the special-shaped hole 37 can be shielded by the sealing cover 40, so as to further improve the safety of use. At the same time, the setting of the block 41 can lock the inner shaft 35 to prevent it from rotating and loosening due to fluid impact.

[0038] See also Figure 1 , Figure 2 , Figure 5The mounting hole 31 is connected with the limiting hole 32 and the circular hole 33. A plurality of mounting holes 31 and the fixing sleeve 30 are provided. The plurality of mounting holes 31 and the fixing sleeve 30 are distributed in a circle. By using the connected mounting holes 31, the limiting hole 32 and the circular hole 33, the plug pin 34 can be inserted into the mounting hole 31 of the pipe to be installed and the mounting hole 31 of the regulating valve body 1 in sequence, so that the limiting block 36 can smoothly continue to pass through the limiting hole 32 and enter the circular hole 33. When the inner rotating shaft 35 is rotated, the limiting block 36 in the circular hole 33 can be synchronously rotated and gradually rotated to a position perpendicular to the limiting hole 32. The plurality of mounting holes 31 and the fixing sleeve 30 distributed in a circle can be fixed at multiple positions on the circumference of the flange ring 2 of the pipe to be installed and the regulating valve body 1, thereby ensuring the fixing effect of the pipe to be installed and the regulating valve body 1.

[0039] See also Figure 1 , Figure 2 The size of the plug pin 34 is compatible with the size of the mounting hole 31, the limit block 36 is compatible with the limit hole 32, and the diameter of the plug pin 34 is highly compatible with the diameter of the mounting hole 31, which facilitates the plug pin 34 to pass through the mounting hole 31, and the length of the plug pin 34 is twice the depth of the mounting hole 31, ensuring that the plug pin 34 can pass through the mounting hole 31 on the outer flange ring 2 of the pipe to be installed and the mounting hole 31 on the outer flange ring 2 of the regulating valve body 1 in sequence. The limit block 36 has a high degree of adaptability with the limit hole 32, so that when the position of the limit block 36 is parallel to the limit hole 32, the limit block 36 can pass through the limit hole 32 smoothly, and when the position of the limit block 36 is no longer parallel to the limit hole 32, a fixing effect is achieved.

[0040] See also Figure 1 , Figure 2 , Figure 3 The plug pin 34 is rotatably connected to the inner shaft 35, and the inner shaft 35 is fixedly connected to the limit block 36. When the hexagonal wrench is inserted into the special-shaped hole 37, the wrench can be applied with force to make the inner shaft 35 rotate smoothly, thereby driving the limit block 36 fixedly connected to the inner shaft 35 to rotate, thereby changing the relative position relationship between the limit block 36 and the limit hole 32, thereby realizing the fixation of the plug pin 34 to the pipeline to be installed and the regulating valve body 1 or releasing the fixation.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The diameter of the sealing cover 40 is matched with the groove, the height of the sealing cover 40 is greater than the depth of the groove, and the sealing cover 40 has a high degree of adaptability with the groove, which makes it convenient to insert the sealing cover 40 into the groove, hide the special-shaped hole 37, and improve the safety of the regulating valve body 1 after installation. The height of the sealing cover 40 is slightly higher than the groove, so that the sealing cover 40 slightly protrudes from the surface of the plug pin 34, and the through groove 44 is exposed outside the plug pin 34, which is convenient for using tools to pull the sealing cover 40 out of the groove.

[0042] See also Figure 2 , Figure 3 , Figure 4 The first card slot 42 and the second card slot 43 are both U-shaped structures, and the first card slot 42 and the second card slot 43 are symmetrically arranged. The symmetrically arranged U-shaped first card slot 42 and the second card slot 43 and the card block 41 together constitute a mechanism for locking the inner shaft 35, and the special structure and position setting of the first card slot 42 and the second card slot 43 ensure that after the inner shaft 35 rotates 90 degrees, the first card slot 42 and the second card slot 43 can still maintain a relative setting, so that no matter whether the pin 34 is used or not, the sealing cover 40 can be stably placed in the groove to avoid the sealing cover 40 being lost when not in use.

[0043] See also Figure 1 , Figure 3 There are multiple blocks 41, which are distributed in a circle. The blocks 41 are matched with the first slot 42 and the second slot 43. The blocks 41 have a high degree of fit with the first slot 42 and the second slot 43, so that when the sealing cover 40 is sealed on the special-shaped hole 37, the blocks 41 can be smoothly inserted into the first slot 42 and the second slot 43 to lock the inner shaft 35. The multiple blocks 41 distributed in a circle can limit the inner shaft 35 at multiple positions of the circle to ensure the limiting effect.

[0044] Embodiment 2:

[0045] See also Figure 2 , Figure 3 , Figure 4 A through groove 44 is provided on the sealing cover 40, an outer mark 6 is provided on the plug pin 34, and an inner mark 5 is provided on the inner shaft 35. The through groove 44 is provided so that when the inner shaft 35 needs to be rotated, a flat tool can be inserted into the through groove 44 to apply force to the sealing cover 40 to separate it from the plug pin 34. The internal mark 5 and the external mark 6 are provided so that the rotation angle of the inner shaft 35 can be indicated.

[0046] See also Figure 2 There are two groups of through grooves 44, and the two groups of through grooves 44 are symmetrically arranged. The two groups of symmetrically arranged through grooves 44 are convenient for using a flat tool to insert from both sides of the sealing cover 40 at the same time, and apply force to the sealing cover 40 from both sides at the same time, which can ensure the balance of force on the sealing cover 40 so that it can be moved out of the groove more smoothly, and the block 41 can also be smoothly separated from the first slot 42 and the second slot 43.

[0047] See also Figure 2 , Figure 3 , Figure 4There are two groups of external marks 6, which are distributed at 90 degrees. The two groups of external marks 6 are used to indicate two different states of the limit block 36 and the limit hole 32. When the two are parallel, the fixation is released, and when the two are vertical, the fixation is completed. The two groups of external marks 6 are distributed at 90 degrees, and the corresponding inner shaft 35 drives the limit block 36 to rotate 90 degrees.

[0048] The implementation principle of the utility model is as follows: first, align the mounting hole 31 on the flange ring 2 of the pipe to be installed with the mounting hole 31 on the flange ring 2 on the outer side of the regulating valve body 1, align the limit block 36 at the bottom of the inner rotating shaft 35 of the plug pin 34 with the limit hole 32, and pass through the two mounting holes 31, the limit hole 32 and the circular hole 33 in sequence; secondly, insert the hexagonal wrench into the special-shaped hole 37, apply force to the wrench, drive the inner rotating shaft 35 to rotate, and rotate it 90 degrees until the inner mark 5 is opposite to the other outer mark 6. At this time, the limit block 36 is perpendicular to the limit hole 32, and the pipe to be installed is fixed to the regulating valve body 1. The first card slot 42 and the second card slot 43 are also set every 90 degrees. When the inner rotating shaft 35 drives the second card slot 43 to rotate 90 degrees, the second card slot 43 just rotates to the position of the next first card slot 42 and is opposite to it; then, the card block 41 of the sealing cover 40 is aligned with the inner rotating shaft 35. The first card slot 42 and the second card slot 43 are aligned, so that the first card slot 42 and the second card slot 43 are inserted into the first card slot 42 and the second card slot 43, and the sealing cover 40 is inserted into the groove and the special-shaped hole 37, and the inner shaft 35 is locked to prevent it from rotating due to the impact of the fluid, which affects the stability of the fixation, until the insertion limit, at which time the sealing cover 40 will protrude a part of the plug pin 34, exposing the through slot 44 outside the groove; finally, repeat the above steps until all the plug pins 34 are installed; when it is necessary to disassemble, use a relatively flat tool to insert the through slots 44 on both sides at the same time, so that the sealing cover 40 leaves the groove and the special-shaped hole 37, the card block 41 leaves the first card slot 42 and the second card slot 43, and the special-shaped hole 37 is exposed, and use the hexagonal wrench to rotate the inner shaft 35 in the opposite direction, so that the inner mark 5 is aligned with the other outer mark 6, and the limit block 36 is parallel to the limit hole 32 again, and the plug pin 34 can be easily pulled out.
