Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of safety valve group pipeline support, especially relates to a double door type pipe support for safety valve group pipeline. BACKGROUND

[0002] In engineering practical application, the safety valve group is an important safety component for protecting equipment and related process systems from overpressure damage. Reasonable pipeline support can ensure that the pipeline system remains stable when the safety valve is opened, avoiding damage to the equipment and related process systems due to vibration or displacement, and thus causing safety production accidents.

[0003] At present, the safety valve group pipeline support has various forms, and generally, different positions of the safety valve group are selected for support according to experience during engineering design, the pipe support forms are mostly T-shaped pipe supports and L-shaped pipe supports, and the installation method is field welding, and there is no special pipe support type for the safety valve group.

[0004] The main factor for selecting the steel structure material and structure type of the pipeline support in engineering design is the pipeline diameter condition. However, the safety valve group may be punched by the outlet pipeline during operation (safety valve take-off), which generates strong impact force, and therefore, a pipeline support with sufficient strength is needed to fix it and maintain the safe operation of the entire valve group and related process systems.

[0005] During the later operation process, if it is found that the strength of the pipeline support in the original engineering design is insufficient, a welded pipe support needs to be installed, but the welding method needs to be performed by fire and has great construction difficulty, and if not handled in time, it may cause safety hazards to normal production.
