Problems solved by technology
[0002] At present, in the process of gas or liquid transportation, the connection between pipelines is generally fixed connection with sealing flange for transportation. However, the sealing flange connection is often loose during the connection process, resulting in gaps between flanges and leakage.
This kind of looseness is difficult to detect, and the longer the flange connection is, the less reliable the connection is, which poses a great safety hazard to the transmission of gas or liquid

The invention discloses a flange used for combined connection of a valve body, which comprises a left flange and a right flange, grooves are provided on the sides close to each other of the left flange and the right flange, and the left flange and the right flange are provided with several threaded holes from left to right, the threaded holes are internally threaded to connect the locking bolts, the left flange and the right flange are connected by locking bolts, the right end of the right flange A baffle is provided, a sealing tube is provided between the left flange and the right flange, both ends of the sealing tube are inserted into the groove, and a sealing gasket is fixedly installed on the outside of the sealing tube. The outer walls of the left flange and the right flange are fixedly connected by an outer spiral pipe. The beneficial effect of the invention is that the leakage of gas or liquid can be avoided, resources can be saved and safety can be ensured at the same time.
Description
technical field [0001] The invention relates to the technical field of flanges, in particular to a flange used for combined connection of valve bodies. Background technique [0002] At present, in the process of gas or liquid transportation, the connection between pipelines is generally fixed connection with sealing flanges for transportation. However, the sealing flange connection is often loose during the connection process, resulting in gaps between flanges and leakage. This kind of looseness is difficult to detect, and the longer the flange connection is, the less reliable the connection is, which poses a great safety hazard to the transportation of gas or liquid. [0003] Those skilled in the art are devoting themselves to solving the above-mentioned technical defects. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, the technical purpose of the present invention is a flange used for combined connection of valve bodies, whic...
