1 is an exploded perspective view schematically illustrating a configuration of a differential pressure chip removing device 11 for pipes according to an embodiment of the present invention.

Referring to the drawings, the differential pressure chip removal device for piping according to the present embodiment, the support plate 17 in the form of a disc, the center portion of the support plate 17, the ball valve 45 is fitted in the upper end and the lower end The first suction pipe 15 to which the suction funnel 13 is fixed, the second suction pipe 29 inserted into the ball valve 45, and a bucket provided at an upper end of the second suction pipe 29. And 39.

As shown in FIG. 3, the support plate 17 is sealed by coupling to a support flange (55 in FIG. 4) of a known shutoff valve (51 in FIG. 4), and the first suction pipe 15 is formed at the center thereof. A through hole (69 in FIG. 3) for penetrating the hole is formed, and a plurality of bolt holes 19 are provided in the edge portion. In addition, four female screws 25 are formed at equal intervals in the region between the bolt hole 19 and the through hole 69. The female screw 25 is a portion that is screwed with the lower male screw 23 of the support bar 21 to be described later.

A bushing 27 is provided on an inner circumferential surface of the through hole (69 in FIG. 2) of the support plate 17, and an o-ring (71 in FIG. 2), which is a packing member, is provided on an inner circumferential surface of the bushing 27. As a result, the outer circumferential surface of the first suction pipe 15 and the inner circumferential surface of the support plate 17 are sealed by the O-ring 71 so that no leakage of fluid occurs in the state of FIG. 3.

The first suction pipe 15 is a pipe whose upper end extends to the upper portion of the support plate 17, and the suction funnel 13 is fixed to the lower end. The suction funnel 13 has an extended shape toward the lower side to cover the chip (c in FIG. 3) widely spread on the bottom of the pipe (64 in FIG. 3) as shown in FIG. 3 and the first suction pipe 15. You can guide inside.

In addition, the ball valve 45 coupled to the upper end of the first suction pipe 15 is a known valve is opened or blocked as the lever 47 rotates. The ball valve 45 may use a cock among the ball valves 45.

The second suction pipe 29 is a pipe having a lower end coupled to the ball valve 45 and an upper end penetrating the bottom surface of the bucket 39 and inserted into the bucket 39. In communication with the first suction pipe (15).

In addition, the upper end of the second suction pipe 29 is bent twice in the 90 degree direction is configured to face the bottom of the bucket 39. This is because when the fluid flows upward through the first suction pipe 15 and the second suction pipe 29 at a high speed and is discharged from the second suction pipe 29, the flow pressure of the fluid is sealed in the bucket 39. The cap 43 is not pushed.

The bucket 39 is a cylinder in which a plurality of holes 41 are formed on the outer circumference thereof, and the ball valve 45 is opened to receive the fluid and chips in the pipe (64 in FIG. 3) flowing upward. ) Discharges the fluid, and the chip serves as a temporary storage inside. To this end, the diameter of the hole 41 has a diameter small enough so that the chip c does not escape, and preferably has a diameter of about 1 mm to 5 mm.

In addition, the upper portion of the bucket 39 to clean the bucket 39 is provided with a sealing cap 43. The sealing cap 43 is a lid that is covered on the upper portion of the bucket 39, the sealing cap 43 is provided with a handle 68 and the outer peripheral surface is in close contact with the inner peripheral surface of the bucket 39.

On the other hand, the auxiliary support plate 35 is fixed to the outer circumference of the second suction pipe (29). The auxiliary supporting plate 35 is a disc having a predetermined thickness, and the through hole 66 is formed at a position corresponding to the vertical portion of the female screw 25.

Four support bars 21 are fixed between the support plate 17 and the auxiliary support plate 35. The support bar 21 is a circular rod, and the external threads 23 and 24 are formed at the lower end and the upper end, respectively. Lower ends of the support bars 21 are vertically screwed to the female screw 25 and the upper ends penetrate the through-hole 66 to the upper side, and then engage with the tightening nut 31.

Accordingly, as the tightening nut 31 is tightened, tensile stress is generated in the support bar 21, and the auxiliary support plate 35 is more strongly coupled to the support plate 17, and accordingly, the first ball valve 45 is first. The suction pipe 15 and the second suction pipe 29 is more strongly coupled.

In addition, since the support bar 21 is positioned at equal intervals around the second suction pipe 29, the support bar 21 provides a supporting force so that the second suction pipe 29 is not bent in the lateral direction. That is, for example, even if a force is applied to the upper end of the second suction pipe 29 in the lateral direction, since the plurality of support bars 21 support the auxiliary support plate 35 horizontally, the second suction pipe 29 is You can always keep the vertical position without bending to the side.

2 to 4 are diagrams for explaining the operation of the differential pressure chip removal device for pipes according to an embodiment of the present invention.

FIG. 2 is a view showing a state in which the perforation hole 59 is already drilled in the pipe 64 by a well-known tapping machine for the pipe work.

As shown, a known branch tee 73 is welded around the perforation hole 59 of the pipe 64 and a shutoff valve 51 is coupled onto the branch tee 73. At this time, the fluid in the pipe is blocked by the blocking plate 53 of the shutoff valve 51 and continues to flow in the direction of arrow a without leaking to the outside.

The shutoff valve 51 is a well-known valve for turning the handle 63 to adjust the position of the shutoff plate 53, and a lead screw 61 is provided therein. The blocking plate 53 is engaged with the outer circumference of the lead screw 61 to perform a linear movement across the flow passage by the rotation of the lead screw 61.

Reference numeral 55 denotes a flange which is usually formed in the shutoff valve 51 as a support flange, and is a place where the support plate 17 of the present invention is hermetically coupled thereto. In addition, the symbol w is a welding site and the symbol c means a chip.

On the other hand, by drilling a hole (59) in the pipe 64 through the drilling operation, the chip (c) is stacked on the bottom of the pipe (64). The chip may be a metal chip or a synthetic chip depending on the material of the pipe. If left alone in a pipe, these chips can be swept along with the fluid, disrupting the flow of fluid, disrupting the operation of valves and other fluid machines, and even causing corrosion of the pipe.

In order to remove the chip from the pipe, the support plate 17 of the present invention is mounted on the support flange 55 of the shutoff valve 51 as shown in FIG. At this time, the blocking plate 53 of the shutoff valve 51 is open and the lower end of the first suction pipe 15 passes through the drilling hole 59 to be introduced into the pipe 64 in which the chip c is stacked. . The suction funnel 13 fixed to the lower end of the first suction pipe 15 is located above the chip c and stands by.

In this state, when the lever 47 is operated to open the ball valve 45 for a few seconds, the fluid that flows inside the pipe 64 is momentarily introduced into the suction funnel 13 to allow the first suction pipe 15 to be opened. And flows into the bucket 39 through the ball valve 45 and the second suction pipe 29 and is discharged to the outside through the hole 41 of the bucket 39. This is in accordance with the theory of hydrodynamics, which occurs because the diameters of the first and second suction pipes 15 and 29 are smaller than the diameter of the pipe 64, and the suction funnel 13 is opened as the ball valve 45 is momentarily opened. The surrounding fluid flows into the first suction pipe having a low pressure.

Meanwhile, as the fluid flows upward, the chip c is also swept up by the fluid and moves upward to reach the inside of the bucket 39. Since the chip c has a larger particle size than the diameter of the hole formed in the bucket 39, it is collected inside the chip 39 without escaping from the bucket 39.

In addition, according to the experiments of the applicant, it can be seen that the chip is most efficiently discharged when the opening time of the ball valve 45 is shortly adjusted to 2 to 3 seconds. In addition, when the amount of chips is too large to discharge all of the chips at once can be completely discharged by repeating the operation of the lever 47 several times.

4 is a state in which the chip removal apparatus of the present invention is removed after the chip is completely discharged from the pipe 64 through the above process, and the blocking plate 53 is sealed.

As shown in the drawing, all of the chips are discharged and clean inside the pipe 64, and the fluid continues to flow in the pipe.

The present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. .

The differential pressure chip removing device for piping according to the present invention made as described above inserts and installs a suction pipe through a drilled hole formed in a pipe for a lubrication operation, but the lower end of the suction pipe is close to the bottom of the pipe on which the chip is stacked. Can be sucked by the difference in the pressure of the fluid by opening for a few seconds, it is also possible to remove the chip in the form of fine powder, in particular by installing a funnel open to the lower end of the suction pipe to the chip even if the chip is scattered widely The removal rate is high and the operation is efficient.
