Description
Technical Field
The utility model relates to a seamless steel pipe's inspection technical field specifically is a vertical crowded experiment external pressure cauldron locking mechanism that destroys of steel pipe.
Background
In order to check whether the performance of the produced steel pipe is qualified or not, a seamless steel pipe production enterprise needs to judge a performance index by obtaining data through an external extrusion destruction experiment; the external pressure kettle is the core equipment for the steel pipe external pressure crushing experiment. The steel pipes of different specifications, materials, wall thicknesses and production batches are subjected to external steel pipe extrusion damage experiment data acquisition, so that the external pressure kettle sealing and locking nut in the extrusion damage experiment is required to be frequently disassembled and assembled for replacing, installing and extruding damage samples. The existing external pressure kettle sealing flange locking adopts two forms, one is to use a large flange circumference to make a circle of bolt holes and tap the end face of the external pressure kettle and then connect and compress the end face by bolts; the other is that the direct locking mechanism and the internal and external threads turned on the inner wall of the external pressure kettle are directly locked by threaded connection, so that the locking workload is very large, the potential safety hazard is serious, and a large number of tools are required to be matched, and the failure rate is high.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a new locking mechanism that is used for external pressure cauldron to seal.
In order to achieve the above object, the present invention is realized as follows:
an external pressure kettle locking mechanism for a steel pipe vertical type crushing experiment comprises an autoclave (4), a test sample (5), a locking nut (1), a safety pin (2) and a high-pressure sealing flange (3); the high-pressure sealing flange (3) is inserted into the locking nut (1), the sample (5) is placed in a barrel of the high-pressure kettle (4), the locking nut (1) is arranged at an inlet of the high-pressure kettle (4), the inserted safety pin (2) is arranged between the locking nut (1) and the high-pressure kettle (4), and the locking nut (1) is prevented from being loosened in threaded connection between the high-pressure kettle (4) through the safety pin (2), so that the locking function is realized.
The external pressure kettle locking mechanism for the vertical steel pipe crushing experiment is characterized in that the external part of a locking nut (1) is cylindrical, threads are arranged on the surface of the locking nut, a conical hole with a stepped structure is formed in the locking nut (1), the appearance of a high-pressure sealing flange (3) is matched with the conical hole in the locking nut (1), and the locking nut and the high-pressure sealing flange (3) are sealed through the stepped structure between the locking nut (1) and the high-pressure sealing flange (3).
The external pressure kettle locking mechanism for the steel pipe vertical crushing experiment is characterized in that longitudinal grooves are formed in the surfaces of a locking nut (1) and the like, and the grooves are used for accommodating a safety pin (2), enabling the safety pin to be located between the locking nut (1) and an autoclave (4) and enabling the safety pin to be in an interference fit state after the locking nut (1) rotates for 1/6 circle.
This locking mechanism has following advantage:
1. the quick sealing and locking can be realized, and the experiment efficiency is improved;
2. the locking nut is installed in the high-pressure kettle by utilizing gravity and is finally tensioned by the safety pin, and extra installation tools are not needed, so that the equipment cost and the failure rate are reduced;
3. the quick locking mechanism does not need to mount a flange locking bolt, so that the labor intensity and potential safety hazards of experimenters are greatly reduced.
