Description
The present invention relates to a piping cleaning system, and more particularly to a piping cleaning system using high pressure water.
As is well known, fluids such as water and gas are transported through piping. When piping is used for a certain period of time, physical and chemical phenomena of the fluid causes scale and sludge to accumulate inside the pipeline, thereby reducing the transport efficiency and contaminating the fluid.
Accordingly, those skilled in the art can replace the pipe or remove the scale and sludge inside the pipe through a cleaning nozzle that uses water pressure as in
The cleaning nozzle disclosed in
It is an object of the present invention to provide a piping cleaning system capable of ensuring smooth entry into piping and cleaning of scales and sludge adhered to the inside of a piping without being affected by the diameter,
In order to achieve the above object, a piping cleaning system according to a preferred embodiment of the present invention includes a high-pressure water supply unit for supplying cleaning water at high pressure, a hose for guiding high-pressure water, and a high- And a nozzle for spraying,

Here, the nozzle is coupled to the hose through the coupling projection of the tightening ring and the pressing projection of the hose insertion part at the end of the hose inserted into the hose insertion part.
In the embodiment of the present invention, the nozzle can eject the high-pressure water forward also through the front incidence hole formed from the flow path to the front of the head portion.
In the embodiment of the present invention, the pressing projection is formed in a sawtooth shape having a gradual slope and a steep slope, and the engaging projection may be formed in a sawtooth shape that engages with the pressing projection.
The present invention may further comprise a fitting with a tightening ring for assisting engagement of the nipple portion interposed between the two hoses arranged in series so as to enable the extension of the length of the hose. The nipple portion includes a disk, a hose insertion portion protruding symmetrically about the disk and having serrated pressing protrusions around the outer periphery, and a through hole penetrating the hose insertion portion and the disk. Further, the tightening ring is disposed around the outer peripheral surface of the end of one hose and the end of the other hose, and has serration-like engaging projections around the inner peripheral surface.
Here, the pressing projection is formed in a sawtooth shape having a gentle inclined surface and a steep inclined surface, and the engaging projection may be formed into a saw tooth shape which engages with the pressing projection.
The present invention may further comprise a discharge water collection adapter for separately providing the discharge path of the pollutant and the discharge water and the guide path of the hose and the nozzle. The discharge water recovery adapter is composed of a guide pipe and a discharge pipe branched in fluid communication with the guide pipe.
The other end of the guide tube may be connected to the piping for cleaning, while one end of the guide tube may be disposed toward the high pressure water supply.
The high-pressure water supply unit includes a reservoir for storing wash water; A pump for supplying the washing water in the storage tank to the rear end; A high-pressure water pipe connected to the pump and supplied with high-pressure water; A pressure gauge interposed in the high pressure water pipe to measure the pressure of the high pressure water; A pressure regulating valve interposed in the high pressure water pipe for controlling the pressure of the high pressure water; A valve for controlling opening and closing of the high-pressure water pipe; A bypass pipe for discharging wash water having an abnormal pressure to the outside; And a connector for fluidly connecting the high-pressure water pipe and the hose.
The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.
Prior to that, terms and words used in the present specification and claims should not be construed in a conventional and dictionary sense, and the inventor may properly define the concept of the term in order to best explain its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.
According to the present invention, it is possible to provide a piping cleaning system that ensures reliable connection of a hose that assists in the supply of high-pressure water and a nozzle that assists in the ejection of high-pressure water.
Particularly, the present invention simplifies the coupling structure of the nozzles to miniaturize the size and shape of the nozzles, thereby allowing a smooth entry into the bent pipe and the small diameter pipe.
The present invention can improve the cleaning effect of the inner wall of the pipe by removing contaminants such as sludge and scale attached to the inside of the pipe through the high-pressure water jet coming out of the nozzle, Unlike the pipe inlet of a permitted pipe, it can be collected through a bypass and the surrounding working environment can be kept clean.
In addition, the present invention enables the extension of the length of the hose to the fitting through the fitment.
