The invention relates to the field of gas pipelines, and particularly discloses a field gas pipeline large-displacement protection device which comprises a plurality of sections of gas pipelines. A protection pipe is arranged between every two adjacent gas pipelines; the ends of the gas pipelines are sleeved with the protection pipes; spherical cavities are formed in the two ends of each protection pipe; hollow spheres are rotatably connected into the spherical cavities; the spheres are fixedly connected to the end part of the gas pipelines in a sleeving manner; corrugated pipes are arranged in the protection pipes; the two ends of the corrugated pipes communicate with the corresponding gas pipelines correspondingly; each protection pipe comprises two connecting pipes which are symmetrically arranged; sliding grooves which are distributed in a circular array mode are formed in the opposite faces of the connecting pipes; a positioning block is arranged between every two adjacent connecting pipes; the inner wall of each positioning block is fixedly connected with the middle of each corrugated pipe; a plurality of sliding rods are arranged at the two ends of each positioning block; the sliding rods are connected into the corresponding sliding grooves in a sliding mode; the gas pipelines are fixedly connected with bases; and the bases are fixedly connected with the ground. The field gas pipeline large-displacement protection device provided by the invention aims to solve the problem of gas leakage caused by fracture of gas pipelines due to large displacement of a rock-soil body during an earthquake.
Description
technical field [0001] The invention relates to the technical field of gas pipelines, and specifically discloses a large-displacement protection device for outdoor gas pipelines. Background technique [0002] Gas pipeline is a pipeline specially used to transport gas. It has the characteristics of convenient connection, convenient use and long service life. Since the distribution of gas resources in my country is extremely uneven, it is necessary to transport the mined gas through gas pipelines, so it is extremely Most of the gas pipelines are in the field environment. After the earthquake and other situations, it is easy to cause large displacement of rock and soil, and the large displacement of rock and soil is easy to cause large displacement of gas pipeline, which makes the gas pipeline on both sides have a height difference. It is easy to cause the connection of the gas pipeline to break easily; and in the field environment, the staff cannot repair the gas pipeline in tim...
