Description

High-pressure steam leak repair unit {HIGH-PRESSURE STEAM PIPE LEAK REPAIR UNIT}

The present invention relates to a high pressure steam leak repair unit.

In general, high-pressure piping that transports steam is designed to be more durable at high temperatures and pressures than general piping. When the pressure of a steam pipe increases, the volume per unit weight decreases, so when the same amount of steam passes through the pipe at the same speed, the pipe size becomes smaller as the pressure increases. Accordingly, there is an API standard used as a standard for piping, and the thickness of the pipe also varies depending on the allowable pressure.

If some of these pipes are damaged due to aging or pinholes, repair work is required to ensure normal operation of the pipes. If the damage to the pipe is minor, it is not difficult to partially repair it, but if the damaged area is large, the entire pipe must be repaired, which reduces productivity and is inconvenient because steam must be blocked throughout the entire pipe. .

The present invention, which was conceived based on the technical background described above, seeks to provide a high-pressure steam leak repair unit that does not require blocking the steam of the entire pipe and can easily repair the pipe.

In the high-pressure steam leak repair unit according to an embodiment of the present invention, a patch part connected to a high-temperature and high-pressure steam pipe leak part to prevent the discharge of steam, a cover part located inside the patch part and connected to the pipe, and a cover part. It is injected into the space between the O-ring portion and the patch portion located between the pipe and the cover portion and may include a filler.

The patch portion may include a patch surrounding the leak portion of the pipe and a steel band located on the upper surface of the patch to secure the pipe and the patch.

The cover part is inserted into a bolt hole formed at a position corresponding to the patch part, and may further include a pressing part that penetrates the cover part and presses the patch part. It is connected to the steel band while placing the patch inside between the cover part and the pipe, and may further include a filling part with discharge holes formed on both sides. The filling portion protrudes from the upper surface toward the cover portion along the edge and may include a filling portion border in which a plurality of holes are formed. The filling portion may have a filling hole corresponding to the position of the patch portion and through which the pressing portion can penetrate.

The high-pressure steam leak repair unit according to an embodiment of the present invention, which was developed based on the above technical background, does not require blocking the steam of the entire pipe and can easily repair the pipe.

Referring to Figures 1 to 3, the high-pressure steam leak repair unit 1000 according to an embodiment of the present invention includes a cover part 100, a patch part 200, a filler 300, and an O-ring part 500. can do.

The cover unit 100 may be provided to cover a high-temperature, high-pressure steam pipe leak area. The cover portion 100 has a larger diameter than the pipe 10 and may be spaced apart from the pipe 10 by a predetermined distance. Accordingly, a space into which the filler 300 can be injected may be formed between the cover part 100 and the pipe 10.

In addition, the cover part 100 is joined on one side of the pipe 10, and is connected to a first cover 110 having a first joint portion 141 formed along the longitudinal direction of the pipe 10 and a first cover 110 on the other side of the pipe 10. A second joint part 142 is formed connected to the first joint part 141 and may include a second cover 120 that seals the first cover 110.

The first cover 110 covers a portion of the pipe 10, and the second cover 120 is connected to the first cover 110 to completely cover the pipe 10. For example, a plurality of first joint sub-holes 141a formed on the first cover 110 and located on the first joint portion 141 and a plurality of first joint sub-holes 141a formed on the second cover 120 and located on the second joint portion 142. A plurality of second joint holes 142a are corresponded to the same position and the joint bolt 143 and the joint nut 144 are connected through bolting, and the first cover 110 and the second joint hole are connected to the pipe 10. The cover 120 can be perfectly adhered. Through this, even if leakage of high-temperature and high-pressure steam occurs, it can be primarily blocked along with the filler 300.

Additionally, the cover unit 100 may have a plurality of injection holes 131a and 131b at both ends of the curved surfaces of the first cover 110 to the second cover 120. When the cover part 100 is coupled to the pipe 10, the filler 300 can be injected into the injection holes 131a and 131b through an injection pump. By injecting the filler 300 into the space between the patch part 200 and the cover part 100 surrounding the pipe 10, a buffering effect can be provided between the patch part 200 and the pipe 10 in preparation for possible leakage. there is.

The patch part 200 is connected to a high-temperature, high-pressure steam pipe leak area to prevent the discharge of steam. The patch portion 200 may include a patch 210 surrounding the leak portion of the pipe 10 and a steel band 220 located on the upper surface of the patch 210 to secure the pipe 10 and the patch 210. .

The patch 210 has a patch groove 210a formed in the center, and the steel band 220 can be inserted into the patch groove 210a and fixed in close contact with the pipe leak.

The patch 210 can be made of various flexible materials, preferably rubber.

The steel band 220 forms a steel band joint 221 at a radius of 90 degrees based on the position where the patch groove 210a is inserted, surrounds the pipe 10, and connects the steel band joint 221 to form a steel band. By bolting the joint bolt 230 and the steel band joint nut 240, the patch 210 and the steel band 220 can be tightly fixed to the pipe 10 to block leakage of high-temperature and high-pressure steam.

The filler 300 may be injected into the space formed between the pipe 10 and the cover portion 100. The filler 300 may be injected in the form of a high-viscosity liquid or gel, penetrate into the leakage area of the pipe 10, and then harden into a solid. Accordingly, the pipe leak area may be blocked by the hardened filler 300.

The O-ring part 500 is located between the cover part 100 and the pipe 10 and can effectively bring the cover part 100 into close contact with the pipe 10. For example, the O-ring portion 500 may be in the form of a circular rubber ring, and may include an O-ring groove 500a in the center that can be coupled and fixed to the pipe 10. The cover portion 100 may be coupled to the O-ring groove 500a by filling the space therebetween. For this reason, even after the filler 300 is injected into the space between the cover part 100 and the pipe 10, the cover part 100 and the pipe 10 are strongly fixed by the O-ring part 500, The filler 300 is hardened inside the cover portion 100 without leaking and can block high-temperature and high-pressure steam.

FIG. 4 is a cross-sectional view of a first embodiment of the high-pressure steam leak repair unit shown in FIG. 1.

Referring to Figure 4, the cover part 100 of the high pressure steam leak repair unit 1000 is inserted into the bolt hole 131 formed at a position corresponding to the patch part, and penetrates the cover part 100 to form the patch part ( It may further include a pressing part 130 that pressurizes 200, and the pressing part 130 may include a bolt hole 131 and a pressing cock 132.

The bolt hole 131 is a hole located in the center of the curved surface of the first cover 110 to the second cover 120, and is placed in a straight line to correspond to the patch portion 200 surrounding the pipe 10 and is a bolt hole. The pressurized cock 132 is inserted into (131) to more firmly block the discharge of high-temperature and high-pressure steam from the patch portion 200. In addition, it can be used for injecting the filler 300 in the same way as the plurality of injection holes 131a and 131b located in the cover part 100. Through this, it is easy to inject the filler 300 evenly from various directions regardless of the location of the pipe leak.

The pressure cock 132 is inserted into the bolt hole 131 located in the cover part 100 to pressurize the patch part 200 to help block leaks in the pipe. For example, the pressure cock 132 may have a circular or spring-shaped shape, and when the pressure cock 132 is rotated, it is pressed against the patch part 200 and the patch part 200 can be easily fixed. .

Figure 5 is a diagram showing the combined state of the piping and filling part shown in Figure 3.

Referring to Figure 5, between the cover part 100 and the pipe 10 of the high pressure steam leak repair unit 1000, the patch 210 is placed inside and connected to the steel band 220, and has discharge holes on both sides. It may further include a filling portion 400 in which 410 is formed.

The filling part 400 can be firmly fixed by coupling the steel band 220 located between the cover part 100 and the pipe 10 to the filling part border groove 421. Through this, when the high-viscosity filler 300 is injected through the bolt hole 131 or the injection holes 131a and 131b of the cover part 100, the steel band 220 or the filling part 400 is filled with the filler ( 300), it can be prevented from deviating from the pipe leak position.

In addition, the filling part 400 forms a 90 degree angle with the steel band joint 221 of the steel band 220 connected to the pipe 10 and can be coupled to the filling part edge groove 421. Even if the steel band 220 is fixed by fitting with the filling edge groove 421 like a piece, fixing may not be easy depending on the viscosity of the filling material 300. For this purpose, when the filling part 400 is coupled to the steel band 220, the filling part border groove 421 primarily fixes it, and secondarily, the steel band joint 221 fixes the filling part border groove 421. ), it can be combined at a 90 degree angle to block pipe leaks more effectively.

The filling part 400 corresponds to the position of the patch part 200, and may be formed with a filling hole 430 through which the pressing part 130 can penetrate and a plurality of discharge holes 410. When the filler 300 is injected into the upper surface of the patch part 200 surrounding the pipe leak through the filling hole 430 of the filling part 400, it is visually checked to what extent the filler 300 is filled in the filling part 400. It is not easy to judge. To this end, when the filler 300 is injected to fill the inside of the filling part 400, the excess filler is discharged through the discharge hole 410, thereby creating a gap inside the filling part 400 with the filler 300. You can judge what is filled without it.

The filling portion 400 protrudes from the upper surface toward the cover portion 100 along an edge and may include a filling portion border 420 in which a plurality of holes are formed. When the filler 300 is injected into the filling portion 400 and the excess filler is discharged through the discharge hole 410, the discharged excess filler is primarily cured. For example, if there is no filling border 420, the excess filler hardens in an indiscriminate shape, resulting in the excess filler sticking to parts other than the pipe 10 or the steel band 220. Hardening may occur, making it difficult to block solidly. The filling portion border 420 provides an approximate primary curing guideline for the filling material 300, and through this, piping leaks can be firmly blocked inside the filling portion 400. In addition, it can play the same role as the discharge hole 410 by discharging excess filler inside the filling portion rim 420 through a plurality of holes formed in the filling portion rim 420.

Figure 6 is an exploded perspective view of a second embodiment of the high-pressure steam leak repair unit shown in Figure 1.

Referring to Figure 6, the cover part 100 of the high pressure steam leak repair unit 1000 is formed along the inner surface of the first cover 110, and includes a first reinforcing joint part connected to the second joint part 142 ( A second reinforcing part (151, 152) is formed along the inner surface of the first reinforcing part 150 and the second cover 120, and a second reinforcing joint part (161, 162) connected to the first joint part 141 is formed ( 160) may be included. The first reinforcement part 150 and the second reinforcement part 160 are located between the pipe 10 and the first cover 110 and the second cover 120, and can surround the entire pipe 10.

Additionally, the first reinforcing joint portions 151 and 152 and the second reinforcing joint portions 161 and 162 are formed of a plurality of tabs, and the tabs may be connected alternately. For example, the first reinforcing joint parts 151 and 152 and the second reinforcing joint parts 161 and 162 are divided into two ends centered on the inner surfaces of the first reinforcing part 150 and the second reinforcing part 160, and each first reinforcing tab (151a, 152a) and second reinforcement tabs (161a, 162a) may be arranged to cross each other. The second reinforcement tabs (161a, 162a) of the second reinforcement joint parts (161, 162) are placed in empty spaces of the first reinforcement tabs (151a, 152a) of the first reinforcement joint parts (151, 152) to form the first reinforcement part (150). When the second reinforcement parts 160 completely surround the pipe 10, they can be connected alternately and arranged so that no voids are created in the first reinforcement joint parts 151 and 152 and the second reinforcement joint parts 161 and 162. there is.

By alternately surrounding the pipe 10 with the first reinforcement joint parts 151 and 152 and the second reinforcement joint parts 161 and 162, the pressure inside the pipe 10 due to pipe leaks can be evenly distributed. Specifically, when the pressure inside the pipe 10 rises due to a pipe leak, excessive force is applied to the patch portion 200 surrounding the pipe leak, and when accumulated, internal steam is discharged, damaging not only the pipe 10 but also the patch. This may cause damage to the unit 200 and the cover unit 100.

When the pressure inside the pipe 10 is applied in the direction of the first reinforcement joint parts 151 and 152 through the configuration of the first reinforcement part 150 and the second reinforcement part 160, the first reinforcement joint parts 151 and 152 are The pressure is relatively distributed to the second reinforcing joint parts 161 and 162, which were alternately coupled while being pushed outward, and the pressure is concentrated in only one direction, thereby preventing the leakage area of the pipe from increasing or damage to other parts.

Figure 7 is a cross-sectional view of a third embodiment of the high-pressure steam leak repair unit shown in Figure 1.

Referring to FIG. 7, the cover portion 100 of the high-pressure steam leak repair unit 1000 is formed along the inner surfaces of the first cover 110 and the second cover 120, and has a protrusion portion 170 with a plurality of protrusions. ) may further be included.

The protrusion 170 is formed on the inner surface of the first cover 110 and the second cover 120 and may be located between the pipe 10 and the cover portion 100. A strong pressure may leak from the pipe 10 due to an increase in air pressure inside the pipe 10 due to a pipe leak. It may be initially dispersed through the filler 300, but if additional pressure leakage occurs inside the pipe 10, the pipe 10 expands, and the pipe 10 comes into direct contact with the cover portion 100 and covers it. Part 100 is damaged and effective pressure blocking cannot be achieved.

Through the configuration of the protrusion 170, the pressure leaking from the pipe 10 can be distributed and blocked. Specifically, when pressure begins to leak due to an increase in air pressure inside the pipe 10, the pipe 10 expands, and the outer surface of the pipe 10 is exposed to the protrusion 170 present on the inner surface of the cover portion 100. They come into contact. The direction of pressure changes toward the inner surface of the pipe 10 in the part that has not yet come into contact with the protrusion 170, and as this is repeated, the protrusion 170 exerts force while contacting the outer surface of the pipe 10 in all directions. It can be dispersed.

With the above-described configuration, an embodiment of the present invention can easily and precisely repair leakage areas of high-temperature and high-pressure steam pipes.

Although the embodiments of the present invention have been described above, the spirit of the present invention is not limited to the embodiments presented in the present specification, and those skilled in the art who understand the spirit of the present invention will understand the spirit of the present invention within the scope of the same spirit, including addition of components, Other embodiments can be easily proposed by changes, deletions, additions, etc., but this will also be said to fall within the scope of the present invention.
