The invention discloses an underwater natural gas repairing hoop with an outer diameter adjusting function. The underwater natural gas repairing hoop comprises an outer shell, a rotating screw, a first extrusion spring, sealing outer shells, a threaded column and an extrusion block, wherein the sealing outer shells are arranged at the front end and the rear end of the outer shell, fixed transverse plates are arranged on the side faces of the sealing outer shell, and fixed vertical plates are arranged on the outer sides of the fixed transverse plates. The underwater natural gas repairing hoop with the outer diameter adjusting function is provided with the first extrusion spring and a second extrusion spring. In the using process, under the elastic force effect of the first extrusion spring, the first extrusion spring can extrude a tough rubber ring, and meanwhile the second extrusion spring can also extrude the tough rubber ring. Meanwhile, a movable limiting column can move in a cylindrical limiting through hole, so that the tough rubber ring can be more tightly attached to a natural gas pipeline. Thus, the functionality of the hoop is improved.
Description
technical field [0001] The invention relates to the technical field of hoops for repairing natural gas, in particular to a hoop for repairing natural gas which is suitable for underwater and has the function of adjusting the outer diameter. Background technique [0002] The full-surround repair hoop provides a fast and economical repair method for fractures, perforations, cracks and other damages of cast iron pipes, steel pipes, cement pipes, copper pipes, aluminum pipes, plastic pipes, and fiberglass pipes. For oil pipes and natural gas pipelines that cannot be repaired by welding and other methods when leakage occurs, the use of stainless steel surrounding repair hoops is an ideal solution without stopping the operation of the pipeline medium. [0003] However, none of the hoops currently on the market can adjust the outer diameter well, which makes the hoops have certain limitations, and cannot repair natural gas pipelines of different sizes. It is easy for water to ente...
