Problems solved by technology

Bolted flange connections are widely used in various industries such as petroleum, chemical industry, aerospace, etc. Since the bolted flange connection system works in a high-temperature and high-pressure working environment for a long time, bolted flanges are prone to bolt elongation and flange warping , Gasket deformation and other problems, and these problems will cause the bolted flange connection system to leak to a certain extent, if the system leaks, it is likely to cause economic losses and safety accidents

Abstract

The invention relates to a leakage-detecting device for a bolted flange connection system. The leakage-detecting device comprises a left pipeline, a right pipeline, a left flange, a right flange, a bolt, and a gasket, non-connecting ends of the left pipeline and the right pipeline are both closed and form a sealing cavity at the inner parts, the inner part of the sealing cavity is provided with a heating mechanism, the outer part of the sealing cavity is provided with a high pressure gas tank, the high pressure gas tank is connected with a balance valve and a flowmeter in sequence via a pipeline and finally communicated with the sealing cavity, and the leakage-detecting device also comprises sensors used for measuring the temperature and pressure in the sealing cavity. According to the leakage-detecting device, the structure is simple, the operation is convenient, whether the bolted flange connection system has leakage phenomenon can be detected, and the leakage rate of the bolted flange connection system can be accurately calculated.

Description

technical field [0001] The invention relates to a leak detection device of a bolt flange connection system, which is used for testing the leakage rate of the bolt flange connection system under high temperature. Background technique [0002] Bolted flange connection is a common connection method in pressure vessels and pipeline equipment. Bolted flange connection refers to compressing two flanges through bolts and sealing the two flanges through gaskets. Bolted flange connections are widely used in various industries such as petroleum, chemical industry, aerospace, etc. Since the bolted flange connection system works in a high-temperature and high-pressure working environment for a long time, bolted flanges are prone to bolt elongation and flange warping , Gasket deformation and other problems, and these problems will cause the bolted flange connection system to leak to a certain extent. If the system leaks, it is likely to cause economic losses and safety accidents. [000...
