The reinforcement mechanism 4 includes In summary: the arc plate 41, the number of the arc plates 41 is two, the inner wall of the arc plate 41 is provided with a groove, so that the arc plate 41 is inserted into the two flanges 2, plugged into the outer wall of the flange 2, and fits the outer wall of the body 1, the first connecting plate 42 is fixedly connected to the two ends of the arc plate 41, the staff moves the arc plates 41 on both sides in turn, the arc plates 41 drive the first connecting plates 42 on both sides to move, the second connecting plate 43 is fixedly connected to the outer wall of the body 1, and fits the outer wall of the first connecting plate 42 and the outer wall of the arc plate 41, the first connecting plate 42 on both sides is fixedly connected to the outer wall of the body 1, and fits the outer wall of the first connecting plate 42 and the outer wall of the arc plate 41, The connecting plate 42 is attached to the second connecting plate 43, and both sides of the arc-shaped plate 41 are also attached to the second connecting plate 43. The stud 44 is fixedly connected to the side of the second connecting plate 43 away from the body 1 and passes through the first connecting plate 42. At this time, the first connecting plates 42 on both sides pass through the stud 44, and the nuts 45 are threadedly connected to the outer wall of the stud 44, and the bottom is attached to the outer wall of the first connecting plate 42. After completion, the staff rotates the nuts 45 on both sides in turn, rotates the nuts 45 on the stud 44, and attaches them to the first connecting plate 42, and the two sides nearest The curved plates 41 are fitted together to reinforce the connection position of the two anti-corrosion pressure pipes. The hidden component 46 is arranged inside the first connecting plate 42. The curved plate 41 is inserted into the two flanges 2. The first connecting plates 42 on both sides are fitted on the second connecting plate 43 under the drive of the curved plate 41 and pass through the studs 44. Finally, the nuts 45 are rotated onto the studs 44 to reinforce the connection position of the two anti-corrosion pressure pipes. The nuts 45 are hidden by the hidden component 46 to prevent other people from rotating them.
[0024] During the specific implementation process, it is worth noting that the staff moves the two bodies 1, and the two bodies 1 drive the flanges 2 to move, and fit the flanges 2 on both sides together. The staff rotates the bolts 3 to fix the two flanges 2 together. There are two arc plates 41, and the inner wall of the arc plate 41 is provided with a groove so that the arc plate 41 is inserted into the two flanges 2. The staff moves the arc plates 41 on both sides in turn, and the arc plates 41 drive the first connecting plates 42 on both sides to move. The first connecting plates 42 on both sides are fitted on the second connecting plates 43, and the two sides of the arc plate 41 are also fitted on the second connecting plates 43. At this time, the first connecting plates 42 on both sides pass through the studs 44. After completion, the staff rotates the nuts 45 on both sides in turn, rotates the nuts 45 on the studs 44, and fits them on the first connecting plate 42.

[0025] Furthermore, the hidden component 46 includes: a shell 461, which is attached to the outer wall of the first connecting plate 42, a slot 463, which is opened on the surface of the first connecting plate 42, and an elastic piece 462, which is fixedly connected to the inner wall of the shell 461 on the side close to each other. When the staff has finished turning the nut 45, the staff moves the shell 461, and the shell 461 drives the elastic piece 462 to move and is plugged into the inner wall of the slot 463. The elastic piece 462 is inserted into the slot 463, and the elastic piece 462 drives the block 464 to move. At this time, the block 464 is squeezed by the slot 463, causing the elastic piece 462 to bend. The jack 465 is opened on the first connecting plate 4 2, the card block 464 is fixedly connected to the side of the elastic sheet 462 away from each other, and is inserted into the inner wall of the insertion hole 465. When the card block 464 moves to the position of the insertion hole 465, the card block 464 is no longer squeezed by the slot 463, and the elastic sheet 462 rebounds, inserting the card block 464 into the insertion hole 465, fixing the shell 461, and covering the nut 45. The elastic sheets 462 on both sides are driven by the shell 461 to insert into the slot 463. At this time, the card block 464 is driven by the elastic sheet 462 to insert into the insertion hole 465, covering the nut 45, thereby hiding the nut 45 to prevent other people from rotating it.
[0026] During the specific implementation process, it is worth noting that after the staff has finished rotating the nut 45, the staff moves the housing 461, and the housing 461 drives the elastic sheet 462 to move, and the elastic sheet 462 is inserted into the slot 463. The elastic sheet 462 drives the clamping block 464 to move. At this time, the clamping block 464 is squeezed by the slot 463, causing the elastic sheet 462 to bend. When the clamping block 464 moves to the position of the insertion hole 465, the clamping block 464 is no longer squeezed by the slot 463, and the elastic sheet 462 rebounds, inserting the clamping block 464 into the insertion hole 465, fixing the housing 461, and covering the nut 45, thereby hiding the nut 45 and preventing other personnel from rotating it.
[0027] Specifically, first, the staff moves the two bodies 1, and the two bodies 1 drive the flanges 2 to move, and fit the flanges 2 on both sides together. The staff rotates the bolts 3 to fix the two flanges 2 together, and then the staff moves the arc plates 41 on both sides in turn, and the arc plates 41 are inserted into the two flanges 2. The arc plates 41 drive the first connecting plates 42 on both sides to move, and the first connecting plates 42 on both sides are fitted on the second connecting plates 43. The two sides of the arc plates 41 are also fitted on the second connecting plates 43. At this time, the first connecting plates 42 on both sides pass through the studs 44. After completion, the staff rotates the nuts 45 on both sides in turn, and rotates the nuts 45 on the studs 44. And it fits on the first connecting plate 42, and the arc-shaped plates 41 on both sides are fitted together to reinforce the connection position of the two anti-corrosion pressure pipes. After completion, the staff moves the shell 461, and the shell 461 drives the elastic sheet 462 to move, and the elastic sheet 462 is inserted into the slot 463. The elastic sheet 462 drives the block 464 to move. At this time, the block 464 is squeezed by the slot 463, causing the elastic sheet 462 to bend. When the block 464 moves to the position of the socket 465, the block 464 is no longer squeezed by the slot 463, and the elastic sheet 462 rebounds, inserting the block 464 into the socket 465, fixing the shell 461, and covering the nut 45.
[0028] Example 2, by Figure 1-3 It can be seen that the two flanges 2 are both fitted with sealing rings 21 on the sides close to each other. The two flanges 2 squeeze the sealing rings 21 to improve the sealing between the two flanges 2. The sealing rings 21 are annular in shape.
