The first flange and the second flange can be quickly aligned and positioned through the plug block and the slot, and deviation and misalignment between the two can be prevented. At this time, the flange holes on the first flange and the second flange are automatically aligned, reducing the tedious and time-consuming alignment and positioning operations of the operator during the flange installation process.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) This solution can realize the rapid centering and positioning of the first flange and the second flange through the plug block and the slot and prevent the deviation and misalignment between the two. At this time, the flange holes on the first flange and the second flange are automatically aligned, reducing the tedious and time-consuming centering and positioning operations of the operator during the flange installation process.

[0020] (2) This solution prevents the sealing ring from being misplaced during installation due to its own elasticity and creep, thereby affecting the sealing performance of the flange connection. At the same time, the inner tubes 1 and 2 are abutted against each other, thereby improving the accuracy of the flange connection.

[0021] (3) This solution allows multiple rods to be inserted into the flange holes at one time through a connecting ring, and then the rotating ring is rotated to rotate the card block and insert it into the card slot to limit and fix the rods. The spring's own elastic force drives the limit plate to move vertically inward through the cooperation of the telescopic rod and insert it into the inner cavity of the rotating ring, thereby limiting the position of the rotating ring and achieving rapid installation of the first flange and the second flange. When disassembling, it is only necessary to manually pull the limit plate outward to drive the limit rod to leave the inner cavity of the rotating ring. This operation is simple and convenient, and multiple flange holes can be installed or disassembled at one time. There is no need to install each flange hole separately to reduce working time and ensure that the flange surface is evenly stressed. BRIEF DESCRIPTION OF THE DRAWINGS
