Abstract

The invention discloses a self-locking flange assembly allowing a high-pressure fluid to pass through. The self-locking flange assembly comprises two flanges; each flange comprises a flange plate anda fluid channel extending outwards from the flange plate; the flange plates of the two flanges are opposite; a sealing gasket is clamped between the two flange plates; the outer end surfaces, away from the sealing gasket, of the flange plates are slopes; the self-locking flange assembly further comprises two holding bodies; each holding body comprises an upper holding ring and a lower holding ring; the upper holding rings and the lower holding rings hold the slopes of the two flange plates respectively; each holding ring comprises a self-locking inclined surface matched with the correspondingslope; and the two holding bodies are fastened through bolts. According to the self-locking flange assembly, the two holding bodies are fastened through the bolts, the two flanges are held through thetwo holding bodies, and the sealing performance can be guaranteed even if the high-pressure fluid passes through the flanges.

Description

technical field [0001] The present invention relates to a flange assembly for high-pressure fluid to pass through. Background technique [0002] When high-pressure fluid flows through the pipeline, it needs to maintain high pressure, so the sealing performance of the flange on the pipeline is relatively high. Common in the prior art cannot maintain good sealing performance on high-pressure fluid pipelines. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned deficiencies of the existing flanges, the present invention provides a self-locking flange assembly for the high-pressure fluid to pass through, which can ensure the sealing performance when the high-pressure fluid flows. [0004] The technical solution of the present invention to solve the technical problem is as follows: a self-locking flange assembly for high-pressure fluid to pass through, including two flanges, the flanges include a flange, a fluid extending outward from the flange In the c...
