[0007] The technical problem to be solved by the utility model can also be further achieved through the following technical solutions: the first flange and the second flange connecting surface are wrapped with an anti-collision sealing ring along the circumferential direction, and the sealing ring is disconnected, and an elongated bolt tube is provided at the opening on one side of the disconnection, and bolt ears are provided at the opening on the other side that match the two ends of the elongated bolt tube respectively.

[0008] The technical problem to be solved by the present invention can be further achieved through the following technical solution: the first sealing groove is provided with a groove matching the limit block, and the limit blocks are provided with four and evenly distributed on the first sealing ring.

[0009] The technical problem to be solved by the utility model can also be further achieved through the following technical solution: a sealing gasket matching the sealing ring is arranged in the sealing groove, and the sealing gasket is a rubber sealing gasket.

[0010] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: the number of bolts for connecting the first flange and the second flange is four and they are evenly distributed between the first sealing ring and the second sealing ring.

[0011] Compared with the prior art, the present invention greatly improves the sealing performance of the flange as a whole by providing a first sealing ring, a second sealing ring, and corresponding first sealing grooves, a second sealing groove, and a gasket in the middle. The present invention is provided with a limit block during assembly, and the bolt hole positions after the upper and lower flanges are aligned and merged are also one-to-one. No secondary adjustment is required by the installer, which greatly improves the work efficiency. After the flange is assembled, the sealing ring is installed, which reduces the risk of collision and breakage during subsequent use and greatly improves the service life.
