In order to avoid insufficient welding of the pipeline during the test. The pipeline is not pressure-proof and is burst, and the splash fragments generated by the burst damage people and objects, and the test pipeline 2 is provided with a pipeline explosion protection mechanism.
Specifically, the pipeline explosion protection mechanism comprises an outer protection cylinder 1 (a cylindrical structure formed by winding and welding a steel plate made of stainless steel metal), and the test pipeline 2 is positioned in the outer protection cylinder 1. Specifically, the welding position on the pipeline penetrates through the center of the outer protective cylinder 1 and is positioned in the outer protective cylinder 1.
Meanwhile, the pipeline explosion protection mechanism further comprises a plurality of clamping pieces 4 assembled and connected to the test pipeline 2, and the clamping pieces 4 are detachably assembled on the outer protection cylinder 1. Specifically, during the test, the pipe is locked by the clip member 4 (the clip member 4 is on the locked pipe, a certain degree of looseness is properly maintained, and complete locking is avoided), and during the test, the clip member 4 is fixed on the outer protective casing 1.
Meanwhile, a plurality of driving plates 11 are fixedly connected to the inner side wall of the outer protection cylinder 1 (the driving plates 11 comprise rectangular parts fixedly connected to the inner side wall of the outer protection cylinder 1, curved parts are integrally formed on the rectangular parts), and splashed water flow pushes the driving plates 11 to rotate the outer protection cylinder 1 in the process of pipeline explosion.
