According to the material, they can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes. In order to filter the liquid inside the existing special-shaped steel pipes, filtering mechanisms are set on them. However, when cleaning the filtering mechanism, it is necessary to stop the water supply to the special-shaped pipe. However, after the water is stopped, a certain amount of backflow will be generated, which will bring some impurities inside the filtering mechanism back to the inside of the special-shaped pipe, which will reduce the cleaning effect.

[0012] Beneficial effects

[0013] The utility model provides a special-shaped steel pipe for fluid transportation with a guide groove inside, having the following beneficial effects:

[0014] (1) For the special-shaped steel pipe for fluid transportation with a guide groove inside, when water is supplied inside the special-shaped pipe body during the use of the utility model, the water liquid will move to the upper side position of the connecting pipe through the inside of the special-shaped pipe body. Under the action of water pressure, the sealing piston starts to move downwards until it separates from the connecting through groove. The connecting slide rod will move downwards, and the elastic element will be compressed and generate a restoring force. When it is necessary to clean the inside of the connecting pipe, the water liquid inside the special-shaped pipe body decreases, the elastic element starts to extend, the connecting slide rod will drive the sealing piston to move upwards until the sealing piston is connected to the connecting through groove. The sealing piston can block the impurities located inside the filter sleeve, improving the cleaning effect.

[0015] (2) For the special-shaped steel pipe for fluid transportation with a guide groove inside, during the use of the utility model, the connecting card block can be rotated forward, the positioning bolt starts to rotate, and the positioning bolt drives the connecting card block to move upwards until the limiting card slot separates from the connecting card block. At this time, the upper side end of the positioning bolt is flipped forward until it separates from the inside of the mounting plate. Finally, the front side end of the sealing cover plate is flipped downwards until the sealing cover plate is separated from the connecting pipe, so that the filter sleeve can be taken out for cleaning, and the operation is simple, convenient and easy to use.
