It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. In this specification, the terms first, second, etc. are used to distinguish one element from another, and the element is not limited by the terms. In the accompanying drawings, some of the elements are exaggerated, omitted or schematically shown, and the size of each element does not entirely reflect the actual size.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a piping cleaning system (1) capable of cleaning scales, sludge and sediments in piping by high pressure water. Fig. 1 shows a piping cleaning system 1 capable of removing scales and the like in a piping P and discharging various sediments together with discharged water to the outside of the piping.

The pipe cleaning system 1 according to the preferred embodiment of the present invention includes a high-pressure water supply unit 100 for controlling high-pressure water supply, a nozzle 300 for spraying high-pressure water to the inner wall of the pipe P, And a hose (200) for supplying the hose (200).

Preferably, the piping cleaning system 1 according to the preferred embodiment of the present invention may additionally include a discharge water collection adapter 400 in the penetration portion for facilitating the entry of the hose into the piping P for cleaning have. The discharge water receiving adapter 400 is connected to the penetration portion of the pipe P by a variety of methods such as a flange, a nipple and a union so as to fluidly connect the hose 200 and the discharge water including the sediment, Etc. to help them collect.

The high-pressure water supply unit 100 is a component that allows the washing water to be supplied to the inner wall of the pipe P by using the nozzle 300 as a means of supplying a predetermined pressure of high pressure.

To this end, the high-pressure water supply unit 100 includes a reservoir T for storing wash water, a pump P for supplying wash water to the rear equipment along the high-pressure water pipe 110 in a high- A valve 140 for controlling the opening and closing of the high pressure water pipe 120, the pressure control valve 130 and the high pressure water pipe 110 so as to supply and / or block the high pressure water, A pipe 150, and a connector 160 for fluidly connecting the hose 200 and the high-pressure water pipe.

The reservoir T may be a movable water tank storing wash water, or alternatively may be replaced by various wash water sources such as a water pipe.

The pressure regulating valve 130 is interposed in the high pressure water pipe 110 as shown in the drawing. The pressure of the high pressure water supplied through the pump P is controlled by the length of the hose 200 and the pipe P, The hose and the piping are likely to be damaged. The pressure of the high-pressure water can be prevented from being guided to the downstream by the pressure regulating valve 130, which is higher than the predetermined pressure.

The high pressure water in a high pressure state higher than the set value will be bypassed to the reservoir T or the like through the bypass pipe 150 without being guided downstream along the high pressure water pipe 110 through the pressure control valve 130 .

The high pressure water supply part 100 can confirm the pressure of the high pressure water to be supplied to the piping P for cleaning through the pressure gauge 120 to the high pressure water pipe 110 in real time, It will help to improve the durability of. Although not shown, the main pressure gauge and the main valve may be further provided, or some of the components may be omitted.

2 to 3, a piping cleaning system according to a preferred embodiment of the present invention disposes a nozzle 300 at an end of a hose 200 for supplying high-pressure water.

The nozzle 300 includes a hemispherical head 310, a tubular hose insert 320 integrally formed at the rear of the head 310, a hose insert 320 at an inner center of the head 310, A plurality of nozzle holes 340 opened obliquely outwardly from the flow path 330 to the periphery (or side surface) of the head part 310, and a plurality of nozzle holes 340 around the hose insertion part 320 As shown in FIG. The plurality of nozzle holes 340 are formed to be inclined at 120 degrees with respect to the center axis of the nozzle 300 in the advancing direction. In addition, the plurality of nozzle holes 340 may be arranged at equal intervals in the circumferential direction at the periphery of the head portion 310.

The nozzle 300 enters the inside of the pipe for cleaning as shown in Fig. The high pressure water is then supplied to the nozzle 300 through the hose 200. The high pressure water is ejected to the plurality of nozzle holes 340 through the passage 330 of the nozzle 300 along the arrow direction. The water jet ejected rearward from the nozzle hole 340 is sprayed toward the inside of the pipe, and the contaminants such as scale, sludge, and sediment can be struck and cleaned inside the pipe. The removed contaminants flow toward the penetration along the spray direction of the water jet and can be drained to the outside of the pipe. In addition, the nozzle 300 of the present invention can easily move forward toward the end of the pipe through the water jet reaction force ejected to the rear side.

The hose inserting portion 320 is inserted into the hose 200 and has a serrated pressing protrusion 321 in the circumferential direction around the outer periphery of the hose inserting portion 320. The tightening ring 350 is disposed around the outer circumferential surface of the hose 200. The tightening ring 350 has a serration-like engaging projection 351 in the circumferential direction around the inner periphery of the tightening ring 350.

The pressing protrusion 321 has a gradual inclined surface 321c directed toward the end of the hose inserting portion 320 and a steeply inclined surface 321d directed toward the head portion 310 so that the hose inserting portion 320 is hose- It is possible to prevent the separation due to the pressure and the vibration of the cleaning liquid, which is a high-pressure water. Accordingly, the engaging projection 351 may be formed in a shape corresponding to the pressing projection 321.

Specifically, the tightening ring 350 is forcibly pressed toward the end of the hose 200 fitted to the hose inserting portion 320. The end of the hose 200 is engaged with the coupling protrusion 351 of the tightening ring 350 and the pressing protrusion 321 of the hose inserting portion 320 to be engaged with the nozzle 300, It is possible to guarantee the coupling state.

The present invention can sufficiently secure the cleaning force as well as the fastening force with the hose even with a small nozzle as compared with the conventional tubular nozzle. That is, according to the present invention, which can adopt a small nozzle, it is possible to smoothly advance the nozzle even at a small-diameter pipe having a diameter of 15 mm or less and at a bent portion of the pipe so as to sufficiently enter the pipe end portion of the pipe, It will be possible.

Figure 4 illustrates another example nozzle. The nozzle of Figure 4 is a further variation of the nozzle shown in Figures 2 to 3, and since it has a very similar structure except for the front incidence hole 341, similar or identical The description of the configuration will be omitted here.

In order to secure a space necessary for forward movement of the nozzle 300 when the adhesion of the scale is serious enough that the forward movement of the nozzle through the jetting of the water jet is not easy, A part of the water can be designed to be injected toward the front of the nozzle 300. [

As shown, the nozzle 300 forms a front incidence hole 341 on a coaxial line with the channel 330, which is in fluid communication with the hose 200. The front incidence hole 341 is formed from the end of the flow path 330 to the front of the head part 310 so that the water jet of high pressure water can be blown forward. The water jet ejected by the front incidence hole 341 separates the contaminants adhered to the front of the nozzle from the inside of the pipe to secure the moving space of the nozzle.

5 to 6 are views for confirming the coupling relationship between the hose and the fitting.

The pipe cleaning system according to the present invention may further include a fitting 500 capable of extending the hose 200 according to the length of the pipe P for cleaning.

As shown, the fitting 500 consists of two tightening rings 550 with a nipple portion 510 provided with a through hole 514.

The nipple part 510 includes hose inserting parts 512 and 513 symmetrically symmetrically with respect to the disk 511 and penetrates the hose inserting part 512 and the axis of the disk 511 and the hose inserting part 513 Through holes 514 are formed. The extension of the length of the hose interconnects one hose and the other hose in fluid communication with each other via a connecting member called a fitting 500. The fitting 500 used for connecting the hose is connected to the hose 200 at a high pressure And a tightening ring 550 for pressing the hose inserting parts 512 and 513 and the hose 200 so as not to weaken the binding of the fittings due to water for a long time due to vibration and pressure.

The hose inserting parts 512 and 513 are inserted into the respective hoses 200 arranged in a line and include serration pressing protrusions 512a and 513a in the circumferential direction around the outer periphery of the hose inserting parts 512 and 513. The tightening ring 550 is disposed around the outer circumferential surface of the hose 200. The tightening ring 550 has a serration-like engaging projection 550a in the circumferential direction around the inner periphery of the tightening ring 550.

The pressing protrusions 512a and 513a are provided with gentle inclined surfaces 512c and 513c directed toward both ends of the hose inserting portions 512 and 513 and sharp inclined surfaces 512d and 513d directed toward the disc 511, The portions 512 and 513 can be easily inserted into the hose 200 when the hose 200 is inserted into the hose 200, but can be prevented from being separated due to pressure and vibration of the high-pressure water. Accordingly, the engaging protrusion 550a may be formed in a shape corresponding to the pressing protrusions 512a and 513a.

Specifically, the tightening ring 550 is forcibly pushed toward the end of the hose 200, that is, the disk, which is fitted to the two hose inserting portions 512 and 513 arranged symmetrically. At this time, the end of the hose 200 is engaged with the coupling protrusion 550a of the tightening ring 550 and the pressing protrusions 512a and 513a of the hose insertion portions 512 and 513, Length extension can be achieved.

7 is a view schematically showing the discharge water recovery adapter 400 mounted in the penetration portion of the pipe P for cleaning.

The discharge water recovery adapter 400 is composed of a guide pipe 410 and a discharge pipe 420 branched in fluid communication with the guide pipe 410. Preferably, the discharge water recovery adapter 400 may be formed of a T-shaped pipe member by connecting the guide pipe 410 and the discharge pipe 420 to each other at right angles.

As shown in Fig. 1, the other end of the guide pipe 410 is detachably coupled to a penetration portion of the pipe P for washing. For example, the other end of the guide pipe 410 may be coupled with a penetration portion of the pipe P and a connecting member such as a nipple or a union by forming a male screw thread around the outer circumferential surface of the guide pipe 410. However, Lt; RTI ID = 0.0 > a < / RTI >

The hose 200 is guided along one end of the guide pipe 410 and is drawn out to the other end thereof along a pipe P fluidly connected to the other end of the guide pipe 410. When the high pressure water is supplied, the contaminant removed through the water jet of the high pressure water sprayed to the inner wall of the pipe through the nozzle 300 mounted at the end of the hose 200 flows to the penetration part together with the high pressure water discharge water. The discharged water containing contaminants travels along the discharge pipe 420 through the other end of the guide pipe 410 in the direction of the arrow, and is guided to a collection vessel other than one end of the guide pipe 410.

The guide pipe 410 is preferably formed to have a larger size than the hose and the nozzle so as to ensure the movement of the hose 200 and the nozzle 300.

Further, in order to ensure smooth discharge of the discharged water, it is preferable that the discharge pipe 420 is arranged downward and the guide pipe 410 is arranged horizontally.
