Technical Field

[0001] The utility model relates to a pipeline anti-pressure device, especially a pipeline anti-pressure device. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

Two wedge-shaped blocks are symmetrically buckled on both sides of the arched bridge frame. The arched bridge frame includes an inverted U-shaped frame. The edge of the U-shaped frame is turned outwards to form a buckling part. The U-shaped frame and the buckling part form a "ji"-shaped structure. The wedge-shaped block includes a vertical support plate and a panel welded together. A plurality of longitudinal support plates are welded at equal intervals on the inner sides of the vertical support plate and the panel.
