Description

Technical Field

[0001] The utility model relates to an elbow leak plugging and sealing fixture, in particular to a pressure pipeline leak plugging and sealing elbow fixture. Background Art

[0002] With the rapid development of economy, the number of pipelines used in facilities such as petroleum, chemical industry, electric power, nuclear energy, military shipbuilding, and civil use has increased. Various high-temperature, high-pressure, toxic, harmful, and corrosive fluid media are often transported in production process pipelines. Most major accidents are caused by pipeline leakage, which brings unbearable disasters and losses to people. Therefore, the safety requirements for pipeline use are very high. Since the weakest part of the pipeline is the elbow, it is easy to leak due to stamping corrosion. When leakage occurs, due to the irregular elbow, the fixture design is very complicated, which greatly restricts the emergency rescue construction of sudden leakage in many production processes. The existing technology mainly adopts the method of cutting the large elbow and putting the small elbow, adding baffles at both ends, and injecting glue to seal to achieve the effect of plugging the leak. However, the difficulty of rapid positioning causes the plugging to be not tight, and the rigidity and sealing of the fixture are poor, so that the fixture bears low pressure during glue injection, and the plugging point bears low pressure, which still cannot effectively solve the plugging and sealing problem after the pipeline leaks.
