Description

[0001] DESCRIPTION [0002] JACKET SLEEVE UNIT FOR VACUUM INSULATED PIPE [

The present invention relates to a jacket sleeve unit for vacuum insulation pipes, and more particularly, to a jacket sleeve unit for a vacuum insulation pipe, in which a connection portion of a vacuum insulation pipe is vacuumed to prevent heat transfer, .

Generally, a vacuum insulation pipe excellent in heat insulation is used as a pipe for transferring cryogenic liquefied gas (nitrogen).

Since the vacuum insulation pipe is composed of a double pipe structure including an inner pipe and an outer pipe, it is not easy to process and install it directly in the field, so that a vacuum insulation pipe spool of a double pipe structure is processed in the pipe factory in advance, The vacuum insulation pipe spool is connected and piped.

The connection of the vacuum insulation pipe is mainly used as a bayonet connection method according to the connection method and a connection method in which a jacket sleeve is welded to the connection part of the vacuum insulation pipe spool.

1 is a view showing a connection state of a vacuum insulation pipe using a conventional jacket sleeve.

The connection of the vacuum insulation pipe with the jacket sleeve 40 is performed by connecting the inner pipe connection part 30 and the outer pipe part 10 to the jacket sleeve 30 while the inner pipe 20 protruding from the outer pipe 10 is butted against each other Both ends of the jacket sleeve 40 are welded to the outer circumferential surface of the adjacent outer tube 10 to seal the inside of the jacket sleeve 40 from the outside.

The air inside the jacket sleeve 40 is discharged to the outside through the vacuum port 50 formed at one side of the jacket sleeve 40 to keep the inside of the jacket sleeve 40 in a vacuum state. The temperature of the cryogenic liquefied gas is prevented from being vaporized due to the heat penetration into the inner pipe connecting portion 30 protruding from the outer tube 10.

However, since the conventional jacket sleeve 40 is connected to the outer tube 10 through welding, the cold air of the inner tube 20 is transferred to the outer tube 10 connected to the inner tube 20, There is a problem that dew condensation occurs at a connection portion between the outer tube 10 and the jacket sleeve 40. [

Further, there is another problem that the work site is contaminated due to condensation generated at the connection portion between the outer tube 10 and the jacket sleeve 40. [

A related prior art is Korean Patent No. 10-1222622 (registered on January 09, 2013).

It is a first object of the present invention to provide a jacket sleeve unit for a vacuum insulation pipe in which a gasket is interposed between the outer tube and the jacket sleeve to prevent condensation from being formed at a connection portion between the outer tube and the jacket sleeve .

A second object of the present invention is to provide a jacket sleeve unit for a vacuum insulation pipe, which enables a jacket sleeve to be easily fixed to the outer surface of the jacket even if not an experienced operator.

For this purpose, the end caps 132 are inserted into the outer tubes 10a and 10b, 134 are formed. The through holes 134 are spaced apart from the outer peripheral surfaces of the outer tubes 10a and 10b so that heat is not transmitted to the outer tubes 10a and 10b. That is, the through hole 134 is formed to have a diameter L2 larger than the diameter 1 of the outer peripheral surface of the outer tube 10a, 10b.

On the one side of the end cap 132 facing one end and the other end of the jacket sleeve 110 are provided a pressing groove portion 138 facing the horizontal portion 122 of the gasket 120 and an inclined portion 124 of the gasket 120 And a pressing protrusion 136 facing the vertical portion 124 of the gasket 120. The pressing protrusions 136 are formed on the outer surfaces 10a and 10b when the jacket sleeve 110 is fixed, 136 and the slant projection 140 press the vertical portion 124 and the slope portion 124 of the gasket 120 and the press groove portion 138 presses the horizontal portion 122 while receiving the horizontal portion 122, do. The gasket 120 pressed by the press protrusions 136, the slant protrusions 140 and the press grooves 138 is deformed so that the outer circumferential surface of the outer tubes 10a and 10b and the outer circumferential surface of the jacket sleeve 110 The jacket sleeve 110 is tightly fixed to one side of the seating groove portion 112 and the end cap 132 and the jacket sleeve 110 is fixed to the outer tubes 10a and 10b without any flow due to the deformation of the gasket 120. [

The through hole 134 of the end cap 132 is supported so as to be spaced apart from the outer peripheral surface of the outer tubes 10a and 10b by the horizontal portion 122 of the gasket 120 fitted to the press-

A second flange portion 142 is formed on the outer circumferential surface of each end cap 132 to fasten the end cap 132 to the jacket sleeve 110. One end of the jacket sleeve 110, And a first flange portion 118 is formed at the other end. The first and second flange portions 118 and 142 are formed in a tapered shape whose outer surface is lowered toward the outer side.

The clamp 144 is disposed on one end side and the other end side of the jacket sleeve 110 so as to press the jacket sleeve 110 against the outer tubes 10a and 10b while pressing the end cap 132 toward the jacket sleeve 110 side .

This clamp 144 is widely used in the art, and the clamp 144 includes three arcuate clamp pieces 146a, 146b, 146c as shown in Figs. 2 and 3. The clamp pieces 146a, 146b and 146c are swingably connected by hinge pins. The first and second flange portions 118 and 142 abut on the inner circumferential surface of each of the clamp pieces 146a, 146b, and 146c, A flange fastening groove 148 having side surfaces corresponding to the tapered shape of the clamp pieces 146a, 146b, 146c is formed along the inner circumferential surface of each of the clamp pieces 146a, 146b, 146c. Protrusions 150a and 150b protruding in parallel to each other are formed at the ends of the clamp pieces 146a and 146c having free ends among the clamp pieces 146a, 146b and 146c connected to each other by the hinge pin. And a nut 154 is fastened to the bolt 152. As shown in FIG.

That is, the first and second flange portions 118 and 142 are fitted to the one clamp piece 146a while the flange coupling groove portion 148 is inserted so as to enclose the first and second flange portions 118 and 142, When the nut 154 is fastened to the bolt 152 in a state where the bolt 152 supported on the protrusion 150a of the clamp piece 146c is fitted in the opening formed in the protrusion 150b of the other clamp piece 146c, The both sides of the groove portion 148 are slid along the tapered surfaces of the first and second flange portions 118 and 142. At this time, the clamp pieces 146a, 146b and 146c are pressed toward each other, As a result, each end cap 132 is pressed and fixed to one end and the other end of the jacket sleeve 110, and one end and the other end of the jacket sleeve 110 are fixedly mounted to the outer tubes 10a and 10b.

Although the clamp 144 with three clamp pieces 146a, 146b and 146c has been described above, the clamp 144 is described in Korean Patent Publication No. 2003-0050647 and Korean Patent No. 10-0920209, And the like can be formed as two clamp pieces.

The jacket sleeve unit 100 for vacuum insulation pipe according to the present invention is formed in such a manner that the gaskets 120 are interposed between the jacket sleeve 110 and the outer tubes 10a and 10b so that the outer tubes 10a and 10b and the jacket sleeves 110 to prevent condensation from being generated on the connection portion between the jacket sleeve 110 and the outer tubes 10a, 10b.

The jacket sleeve unit 100 for a vacuum insulation pipe according to the present invention can be manufactured by pressing the end cap 132 against the jacket sleeve 110 using a clamp 144 that is easy to operate, The jacket sleeve 110 can be easily fixed to the outer tubes 10a and 10b so that the jacket sleeve 110 can be easily fixed to the outer tubes 10a and 10b So that the time and cost can be remarkably reduced.
