A leak-proof gas pipeline flange

Abstract

The invention belongs to the technical field of flanges, and specifically relates to an anti-leakage gas pipeline flange, which includes a left flange, a right flange, a locking module and a sealing module; A number of bolts are arranged between the flange and the right flange, and the tails of the bolts are provided with hexagonal nuts, the hexagonal nuts are fixedly connected to the No. A locking module is arranged on the flange. The invention uses the vibration of the pipe body to make the weight push the rocker to move up and down, so that the rotating disk rotates. The rotating disk makes the second gear rotate in one direction through the shift block and the right-angle groove, and the second gear re-tightens the hexagonal nut through the first gear. , improve the efficiency of the automatic locking of the hexagonal nut, which is beneficial to improve the sealing efficiency; use two annular sealing bags to squeeze each other, the plasticine inside the two annular sealing bags flows, and the left flange, the right flange and the pipe body Fill the gap between the pipes, effectively improving the sealing effect of the pipe body.

Description

technical field [0001] The invention belongs to the technical field of flanges, in particular to an anti-leakage gas pipeline flange. Background technique [0002] Pipe flanges are generally disks or rings forming an outer rim at the ends of pipes that are used to join a pipe to another pipe or pipe fitting. The flange usually has a series of bolt holes provided around its periphery to allow the pipe to be secured at the joint. A flange joint refers to the end-to-end connection of two pipes, where the connecting parts each have a flange that bolts the ends of the pipes together. Typically, rubber gaskets are provided between the faces of adjoining flanges of the flange joint. It is important that the faces of the adjoining flanges be as smooth and flat as possible to ensure a proper seal at the joint. When existing rubber gaskets are in contact with flanges, small gaps tend to appear. [0003] There are also some technical solutions for pipeline flanges in the prior art....

AI Technical Summary

Problems solved by technology

However, when the pipe flange is subjected to vibrations, the bolts at the connection position of the two flanges tend to loosen, which leads to the loosening of the flange and the leakage of the pipe. Therefore, a leak-proof gas pipe flange is proposed. It can automatically lock when the pipe body vibrates and the flange becomes loose, improving the sealing efficiency
