Description

Technical Field

[0001] The utility model relates to the field of pipe fittings, in particular to a stainless steel oil pipe joint device. Background Art

[0002] A pipeline refers to a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. Usually, after being pressurized by a blower, compressor, pump, boiler, etc., the fluid 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. Pipelines have a wide range of uses and are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] An oil pipe is a pipeline used to transport oil. An oil pipe joint is a connecting component used to connect two oil pipes. In the authorized Chinese utility model patent "CN215950660U, titled: A Stainless Steel Oil Pipe Joint Device Facilitating Installation", it sets fixing rings on the first pipe and the second pipe, makes a preliminary connection through a movable ring, and then fixes it through a limiting device, making the installation more stable. By setting the connecting end faces of the fixing ring and the movable ring as stepped and installing sealing gaskets on some end faces, it is convenient for the movable ring to be screwed with the fixing ring and can effectively prevent liquid from flowing out of the connection. However, in the above application, the movable ring and the limiting device are completely separated from the joint position during disassembly, resulting in the parts in the limiting ring and the limiting device being easily lost in the disassembled state, affecting the connection of the oil pipe. Moreover, the above application only relies on the limiting device to fix the pipe joint, and the pipe is prone to looseness or even separation when being dragged, affecting the stability of the oil pipe connection.
