The first positioning mechanism 20 and the mounting mechanism 10 can also be pivotally connected, the first positioning mechanism 20 is provided with a pivot, the mounting mechanism 10 is provided with a sleeve, the pivot is fitted in the sleeve, a helical groove is arranged on the side wall of the pivot, and a plurality of clamping grooves are arranged on the upper inner side wall of the helical groove. The pivot and the sleeve can also jointly adjust the height of the first positioning mechanism 20 as needed.

[0047] In some embodiments, the opening pressure relief device 100 further comprises a connecting pipe 40 and a second positioning mechanism 50. One end of the connecting pipe 40 is connected with the clamp plate valve 30. The second positioning mechanism 50 is connected with the mounting mechanism 10 and clamps the connecting pipe 40.

[0049] For example, the opening pressure relief device 100 can further comprise an opening machine 60, which is arranged on the connecting pipe 40. After the clamp plate valve 30 and the connecting pipe 40 are installed, the opening machine 60 can be used to perform the opening pressure relief operation on the pipeline 200.
