Description

Technical Field

[0001] The utility model relates to the field of cleaning, in particular to a large pipeline high-pressure cleaning nozzle. Background Art

[0002] Pipe cleaning refers to cleaning the pipeline to restore the surface of the material itself. After cleaning, a dense chemical passivation film is formed on the clean metal surface, which can effectively prevent the re-generation of dirt and effectively protect the equipment. The nozzle is a very critical component or even the main component in many types of spraying, misting, oil spraying, and sandblasting equipment. When cleaning, a high-pressure nozzle is generally used to spray water. A large-scale pipeline high-pressure cleaning nozzle disclosed by the search application number CN202021217076.7 records that the cleaning liquid flows into the main hole of the inlet and outlet shaft through the liquid inlet joint, and part of the cleaning liquid is discharged directly from the nozzle at one end of the inlet and outlet shaft, and the rest of the cleaning liquid is discharged from multiple side holes. The side hole is connected to the buffer tank, and the cleaning liquid is discharged through the nozzle after entering the buffer tank.

[0003] Compared with the diversion type, the independent liquid outlet structure of the side nozzle of the buffer tank has less energy loss of water flow and reduces the turbulence problem at the main hole diversion point, thereby improving the impact force and cleaning efficiency of the nozzle jet, and the cleaning block adopts an independent multi-layer split structure, which is easy to replace. However, the above description still has the following defects in actual use: the structure of the device is relatively complex when used, and there is a lack of connection and installation structure, which limits the use of the nozzle inside the pipeline. Therefore, it is necessary to design a practical large-pipe high-pressure cleaning nozzle. Utility Model Content
