Description

Flange cover {

The present invention relates to a flange cover, and more particularly, to a flange cover that receives a fluid leaked from a flange and prevents fluid flowing through the pipe from leaking into the inside of the vessel.

A number of pipes are installed inside the vessel to transport various fluids including gas and oil. Considering the overall size of the vessel as well as the internal structure of the vessel, which is divided into various workplaces, it is difficult to form all the pipes installed in the vessel into one body without connecting portions. Therefore, the pipe may be elongated using a connecting portion such as a flange structure, or may be divided into several branches to connect the respective sections to each other. However, due to the nature of the connecting portion having the joint portion, it is inevitably vulnerable to leakage as compared with the case where the pipe is integrally formed.

If the fluid flowing inside the pipe leaks to the outside of the pipe through the connecting portion and leaks into the inside of the pipe, there arises a problem that the vessel is damaged or a serious safety accident occurs. For example, when ultra-high or low-temperature fluid flowing inside a pipe leaks through the flange connection and leaks to the workplace inside the vessel, it can cause serious injury to workers in the workplace as well as low temperature damage have. In addition, leakage of oil, such as oil, can lead to marine pollution problems without ending the pollution of the workplace, resulting in serious environmental problems. Therefore, it is necessary to confirm whether or not the fluid leaks from the flange which is the connecting portion of the pipe.

In order to prevent such a problem, conventionally, it is checked in advance whether or not leakage occurs at the flange connecting portion. In case leakage occurs, the opening / closing valve is opened to remove the leaked fluid. However, even if it is confirmed that leakage does not occur, there may be a sudden leakage of the fluid depending on the pressure or the situation inside the pipe. In such a case, if the flange is suddenly released for maintenance, the internal fluid flows down to the inside of the vessel There is a problem.

Therefore, there is a need for a technique for checking at a glance whether a fluid leaks from time to time, and for minimizing the human energy required to treat a leaked fluid.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, with reference to Figs. 1 to 3, a flange cover according to an embodiment of the present invention will be described in detail.

1 is a perspective view showing a flange cover according to an embodiment of the present invention.

1, a flange cover 1 according to an embodiment of the present invention includes a housing space 15 in which a housing space 15 for accommodating a flange F of a pipe P is formed, And a drain container 20 detachably connected to the drain outlet 12 and communicating with the accommodation space 15. The housing 10 is formed with a drain outlet 12,

The flange cover 1 according to the embodiment of the present invention can prevent the leaked fluid from flowing down into the vessel. More specifically, the housing 10 accommodates the flange F, so that even if the fluid leaks from the flange F, the leaked fluid is received in the drain container 20, It is possible to prevent damage or contamination.

Hereinafter, the structure of the flange cover 1 having such features will be described in more detail with reference to FIGS. 2 to 3. FIG.

FIG. 2 is a cross-sectional view of the flange cover of FIG. 1 cut along the A-A 'direction, and FIG. 3 is an exploded perspective view of the flange cover of FIG. 1.

The housing 10 has a structure in which a housing space 15 is formed therein and surrounds the entire periphery of the pipe P and the flange F so as to surround and enclose the entire flange F. Therefore, when the fluid that has flowed inside the pipe P leaks from the flange F, it is accommodated in the accommodation space 15. At this time, the housing 10 is formed with a drain outlet 12 communicating with the outside under the flange F, so that the leakage fluid contained in the housing space 15 can be discharged to the drain outlet 12. Particularly, a drain container 20 is coupled to the drain outlet 12, so that the leakage fluid contained in the housing space 15 can flow into the drain container 20 and is received in the drain container 20. Therefore, by separating the drain container 20, the leakage fluid can be easily removed.

2, the housing 10 surrounds the pipe P at the lower portion of the flange F and protrudes toward the flange F to seal the fluid leaked from the flange F to the drain container 20 And a guiding wall 11 for guiding the guiding wall 11a.

The guide wall 11 can serve as a kind of barrier wall. When the fluid leaks from the flange F and is received in the accommodation space 15, the gap between the outer surface of the pipe P and the housing 10 Thereby preventing the leakage fluid from flowing down along the space. This structure of the guide wall 11 makes it possible to prevent the leakage fluid from flowing along the outer surface of the pipe 10 even if the housing 10 and the pipe P are not in close contact with each other. The leakage fluid contained in the accommodation space (15) by the guide wall (11) is guided and flows into the drain container (20).

At least a part of the bottom surface of the housing 10 where the drain outlet 12 is formed may be recessed toward the drain outlet 12 to form the drain groove 13. Therefore, the leakage fluid is guided to the drain container 20 by the guide wall 11 and flows into the drain outlet 12 by the drain groove 13. [

The drain container 20 has a cylindrical shape and is configured to store a fluid therein. The drain container 20 is detachably coupled to the drain outlet 12. The inside of the drain container 20 is in communication with the receiving space 15 so that the receiving space 15 inside the housing 10 and the inside of the drain container 20 are connected.

The drain container 20 may have a spiral formed on the inner circumferential surface or the outer circumferential surface of the inlet so as to be spirally coupled to the housing 10. That is, the second spiral 24 is formed at the end of the inlet side of the drain container 20 and the first spiral 14 connected to the second spiral 24 is formed in the housing 10, The drain container 20 can be easily coupled by rotating the drain container 20 to the housing 10 by using the second spiral 14 and the second spiral 24 and by rotating the drain container 20 in the opposite direction to release the spiral coupling, .

The first spiral 14 may be formed on the outer peripheral surface or the inner peripheral surface of the drain discharge port 12. [ More specifically, when forming the first spiral 14 on the outer circumferential surface of the drain outlet 12, a second spiral 24 that can be connected to the first spiral 14 is formed on the inner circumferential surface of the drain vessel 20, When the first spiral 14 is formed on the inner circumferential surface of the drain outlet 12, the second spiral 14 connected to the outer circumferential surface of the drain container 20, So that the inner circumferential surface of the drain outlet 12 and the outer circumferential surface of the drain vessel 20 are helically connected. The first spiral 14 is formed on the outer circumferential surface of the drain outlet 12 and the second spiral 24 is formed on the inner circumferential surface of the drain container 20. However, the present invention is not limited thereto, and the drain outlet 12 And the second spiral 24 is formed on the outer circumferential surface of the drain container 20 so that the drain container 20 is partially inserted into the housing 10 so as to be spirally engaged with the first spiral 14 .

In order for the leakage fluid accommodated in the accommodation space 15 to be guided by the guide wall 11 and the drain groove 13 to be more easily accommodated in the drain container 20 through the drain outlet 12, It is more preferable that the drain outlet 12 is partially protruded to the outside of the housing 10 so that the outer circumferential surface of the drain outlet 12 and the inner circumferential surface of the drain vessel 20 are helically connected.

As described above, the drain container 20 can be detachably coupled to the housing 10 by the spiral connection, so that the drain container 20 can be easily exchanged. For example, when the amount of fluid leaking from the flange F is large, it can be immediately replaced with a larger drain container 20 so that the leaked fluid overflows to the outside of the drain container 20 or the flange cover 1 It is possible to prevent falling into the inside of the vessel.

Further, at least a part of the drain container 20 is made of a transparent material, and the fluid contained therein is immediately visually confirmed. Therefore, it is possible to easily check whether the fluid leaks by checking the fluid leaked to the drain container 20, and visually confirm the leaked amount or speed. Thus, when the amount of fluid leaked is high or the speed is high, The large drain container 20 should be prepared in advance so that the replacement operation can be performed immediately.

When the fluid leaks from the flange F, the leaked fluid is stored while flowing down to the drain container 20 through the drain outlet 12 while being primarily accommodated in the receiving space 15. It is also possible to remove only the drain container 20 from the housing 10 to discard the fluid stored in the drain container 20 and re-combine with the housing 10 to replace the drain container 20 with the larger drain container 20, 10). ≪ / RTI > However, if the softening is prolonged and leakage occurs repeatedly, the inside of the flange cover 1 may be contaminated or corroded. In this case, the housing 10 of the flange cover 1 should be replaced. The flange cover (1) according to the present invention allows the housing (10) to be detached, so that the replacement operation can be simplified.

3, the housing 10 includes a first housing 10a covering a part of the outer circumferential surfaces of the pipe P and the flange F and a second housing 10b joined to the first housing 10a, (10b).

The first housing 10a and the second housing 10b are fixed by bolts B and n. The first housing 10a and the second housing 10b are provided with engaging portions 17 formed at both ends of the first housing 10a and the second housing 10b, When the bolt B is inserted into the coupling hole 18 of the selected one coupling portion 17, the nut N is coupled from the other coupling portion 17 side to the first housing 10a and the second housing 10b.

3, the flange cover 1 can be separated from the drain container 20, the first housing 10a, and the second housing 10b, respectively, so that the flange cover 1, There is no fear that the fluid will flow into the vessel when the flange cover 1 is removed to remove the leakage fluid. In other words, since the leakage fluid contained in the accommodating space inside the flange cover 1 is all stored in the drain container 20, the leakage fluid can be easily removed only by separating the drain container 20, The first housing 10a and the second housing 10b are separated from each other so that the inside of the flange cover 1 can be cleaned without repairing the flow of leakage fluid and the maintenance work of the flange F or the replacement operation of the housing 10 It is possible to perform smoothly.

The flange cover (1) can be applied to the entire flange installed on the joint of the pipe. The flange cover (1) is characterized in that the work time required to cope with the leakage is reduced and the human energy wasted in the repair work can be reduced very efficiently. When the flange cover is disassembled for reinforcement work of the flange, there is no fear that the fluid flowing in the flange cover will flow down.
