Description

[0001] The present invention relates to a vertical pipe flange,

The present invention relates to a mechanism for preventing the leakage of fluid by piping leakage, and more specifically, to a leakage piping spill prevention mechanism of a vertical piping flange for preventing leakage of fluid on pipes of various facilities used in offshore plants and the like .

In general, piping flanges used in offshore plants have a high leakage rate. In the case of piping with high pressure fluid, the scattering of fluids in the flanges not only physically damages surrounding operators, but also causes volatile fluids to leak If it is scattered, the vaporization is accelerated and the explosion risk is caused.

In particular, if toxic or flammable liquid leaks through the flange, it may be necessary to prevent scattering and to collect and isolate the leaked liquid to protect the operator and the workplace from further hazards. It is most desirable to fundamentally prevent leakage from the flange. However, in a situation where it is practically impossible, the reduction of the scattering phenomenon in the case of the flange leakage contributes to the improvement of the safety of the operator.

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

The present invention proposes a mechanism for preventing leakage of fluid from a flange (12) of a vertical pipe (10). But is not limited to, vertical piping 10 and flange 12, among pipings that are susceptible to leakage of high-pressure fluid from an offshore plant or the like. At present, a suitable protective member for the flange 12 of the vertical pipe 10 is not commercialized. Therefore, a leakage preventing cover using a metal is installed and then a collecting / discharging member using a nonmetal is additionally provided . Therefore, it is insufficient to secure safety compared with a case where a relatively large amount of air is required.

The cover 20 according to the present invention has a structure in which the upper plate 21, the lower plate 22, and the side plates 23 are wrapped around the flange 12 to prevent the fluid from scattering. 1, the upper plate 21 is disposed on the upper side of the upper flange 12, the lower plate 22 is disposed on the lower side of the lower flange 12, the side plates 23 are disposed on the upper plate 21, And the lower plate 22. The cover 20 is formed by integrally forming the upper plate 21, the lower plate 22, and the side plate 23 as shown in FIG. 2 and bending the tool 20 manually. In this case, the top plate 21 and the bottom plate 22 are divided into a plurality of sections 27.

According to the detailed construction of the present invention, the cover 20 is characterized by having a support plate 25 extending from the upper plate 21 and the lower plate 22 so as to be in close contact with the vertical pipe 10. The support plate 25 extends in a reduced diameter than the side plate 23 to enclose the vertical pipe 10. The upper plate 21, the lower plate 22 and the side plates 23 are not in contact with the flange 12 by the support plate 25 and are kept at a constant interval. The support plate 25 leaks to the flange 12 to prevent the liquid stored in the cover 20 from leaking again.

According to the detailed configuration of the present invention, the lower plate 22 of the cover 20 is formed with a gradient 22a so as to be lowered from the center to the edge. In FIG. 1, when the lower plate 22 is formed into a generally convex curved surface, a gradient 22a lowering from the edge is formed. This serves to collect the fluid leaking between the flanges 12 onto the gradient 22a and temporarily store them.

According to the detailed configuration of the present invention, the cover (20) is provided with a drain tube (15) at the edge of the lower plate (22). 1, the drain tube 15 is provided at a lower end side of the lower plate 22 with a predetermined length. In this way, the fluid collected at the lowest part of the gradient 22a can be quickly discharged to the drain tube 15. [

According to the present invention, the fixing means 30 separably supports the cover 20 on the vertical pipe 10 and the flange 12. The fixing means 30 is divided into two parts in which the support plate 25 is fixed to the vertical pipe 10 in close contact with each other and both ends of the side plate 23 are in close contact with each other. Various embodiments of the fastening means 30 are shown in Figures 1-3.

According to the detailed configuration of the present invention, the fixing means 30 includes a fastening plate 32 formed on the cover 20 and fastened with bolts, a cicadic ring 34 attached to the cover 20 in a male and female form, a cover And a hose clamp (36) for covering the outer surface of the hose (20). The fastening plate 32 extends in a flange shape at both ends of the side plate 23 and the support plate 25 as shown in FIG. 2, and a bolt is inserted into the fastening hole and tightened with a nut. As shown in FIG. 3, the cicada ring 34 is fixed to both ends of the side plate 23 and the support plate 25 so that the cicadas 34 of the male type are hooked and engaged with the cicadas 34 of the female type. The hose clamp 36 engages the outer surface of the support plate 25 as shown in FIG. 1, and then tightens the bolts to reduce the diameter. The fastening plate 32 of the fastening means 30, the cicada ring 34, and the hose clamp 36 can be selected and installed in an appropriate combination.

According to the present invention, the sealing means 40 is provided on the cover 20 so as to prevent the leakage of the fluid from the flange 12. The sealing means 40 is installed so as to block a gap through which the fluid leaks from the vertical pipe 10 and the cover 20 provided on the flange 12.

According to the detailed configuration of the present invention, the sealing means 40 is selectively applied to the sealing material 42 stacked on the cover 20 and the packing 45 fitted to the cover 20. [ The sealing material 42 is formed by applying a material such as rubber to the support plate 25 and integrally laminating the same. The packing 45 is formed separately and applies a structure to be sandwiched between both ends of the upper plate 21, the lower plate 22 and the side plate 23 and the incision 27. Of course, the sealing material 42 of the sealing means 40 and the packing 45 may be selectively applied.

On the other hand, as a modified example of the present invention, it is possible to adopt a configuration in which rubber having high elasticity is applied to the entire sides of the cover 20 of Fig. 2 and integrated. That is, if the entire contour of the cover 20 including the incision 27 is insert-molded into the sealing member 42, quick installation and tight sealing can be performed simultaneously even if the packing 45 is omitted.

1, when the cover 20 of the present invention is installed so as to surround the flange 12 on the vertical pipe 10 and then a separate hose (not shown) is connected to the drain tube 15, . As shown in FIG. 4, when the cover 20 of the present invention is installed in the horizontal pipe, the drain tube 15 can be positioned at the lower end to perform the same function of preventing leakage and scattering of the fluid.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. Accordingly, such variations or modifications should fall within the scope of the utility model registration claims of the present invention.
