Description

Heat-Retaining Structure of Steam Pipe Device and Method of Using Thereof}

The present invention relates to a heat insulation device for a steam pipe and a construction method using the same, and more particularly, a first pipe and a heat insulating material on an outer circumferential surface of a known steam pipe that supplies steam to a soup pot, including peripheral devices such as a pressure control and a shutoff valve. The outer spring pipe, the second pipe, etc. are configured to be sequentially installed, but the vacuum layer is formed in the spaced space of the first and second pipes to insulate and insulate the heat inside the steam pipe to increase the efficiency of the steam piping device, The present invention relates to a heat insulation device for a steam pipe and a construction method using the same, which minimizes the possibility of injury to the user such as burns by preventing the pipe from being exposed to the outside and preventing the gap between the steam pipe and the heat insulation device.

The present invention relates to a thermal insulation device for a steam pipe for feeding that can be cleaned without the risk of burns, and a construction method thereof, and more specifically, to steam to cook rice or soup using steam in a school, military, public places, etc. The present invention relates to a heat insulation device for safe and heat-resistant steam pipes that can maintain warmth and prevent burns as well as to prevent frequent burns when cleaning steam pipes for supplying steam to pots. .

Meal facilities are commonly used to refer to various devices and systems that can make rice and soup in large quantities for the meals of many people in schools, the military, and other groups. In the case of cooking utensils, in the past, the cauldron was used, and because of limitations in capacity and discomfort during heating or heat supply, cooking utensils such as soup pots using steam are frequently used.

The cooking utensils using steam are provided with steam which is a heat source through the steam pipe, and the cooking utensils are formed in a similar form to the steam generating system used in the heating boilers. Convenience, as well as high thermal efficiency, ease of operation and cooking, are now used in most school meal facilities.

Conventional feeding steam pipe is connected to the steam generating device installed in or around the feeding place serves to supply steam to the steaming pot, the steam pipe may be embedded in the wall, ceiling, floor of the feeding place. Although it may be exposed to the outside due to the hassle of construction, in particular, the part connected to the soup pot is impossible to be buried due to the need to be connected to the soup pot and has to be exposed to the outside.

Referring to a schematic laminated structure of a conventional steam feed pipe, a heat insulating material having a predetermined thickness is laminated on the outer surface of the steam pipe for thermal insulation, and the heat insulating material is made of a known glass wool insulating member, and is formed on a heat insulating tape such as a magic tape. It is wrapped around the steam pipe. In addition, the outer surface of the insulating tape is laminated with a heat insulating cover made of APS (Amino Propyltriethoxy Silane) to tin-containing material to take a structure that ensures a part of the thermal insulation.

The steam pipes that supply steam to these food facilities, cooking utensils, and cooking utensils are cleaned several times a day for hygiene reasons, and cleaning is mainly performed by spraying hot water or disinfectant water on the soup pot and surrounding steam pipes. In particular, when cleaning the steam pipe and its surroundings, the high surface temperature of the steam pipe often causes the cleaning personnel to be easily burned. To prevent this, spray the hose with a long hose at a certain distance from the steam pipe. In this case, there is a disadvantage that the cleaning is not done neatly, and there is a problem that a part of the body may be inadvertently contacted with the steam pipe by the hose, and there is a problem that a burn may easily occur. there was.

In addition, according to the heat insulation device of the steam pipe is to cover the surface of the steam pipe having a high surface temperature with a heat insulating material can prevent the above-mentioned problems of the primary, but because the heat insulating material is wrapped with a heat insulating tape, etc. When it is frequently touched, the adhesive force of the insulating tape is lowered, causing the insulation material to fall off and rattle on the outer circumferential surface of the steam pipe. In addition, due to this, the water used for cleaning the water into the insulation is unnecessarily changed, and the steam in the steam pipe is changed into condensate instantaneously, which may cause the steam cooker not to operate, and the insulation is pressed against the surface of the steam pipe by moisture. There has been a problem that impairs the fragility and thermal insulation of the overall insulation device.

In particular, if water comes into contact with the cracks or gaps between the steam pipe and the insulation device due to a decrease in the adhesive strength of the insulating tape and deformation of the insulating material, the water heated by hot steam splashes and burns the body of the cleaning personnel. A fatal problem could be pointed out.

It is characterized by comprising a high density glass fiber stitched in the heat transfer direction.

Although the above technique can have a more reliable thermal insulation effect by changing the material and structure of the glass fiber in a state where the space is sealed in a vacuum state, the surface of a very hot steam pipe only in the space sealed in a known vacuum state Not only is insufficient to insulate and insulate, there is no mention of a configuration that can seal the both ends of the insulation is not easily understood.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is a cutaway perspective view showing the basic shape of the heat insulating device of the steam pipe according to the present invention, Figure 2 is an exploded perspective view showing a schematic laminated structure of the heat insulating device of the steam pipe according to the present invention, Figure 3 It is sectional drawing which shows schematic sectional structure of the heat insulation apparatus of the steam piping which concerns on this invention.

As can be seen from Figure 1, the heat insulation device of the steam pipe according to the present invention includes a peripheral device such as a pressure control and shut-off valve in accordance with the present invention on the outer peripheral surface of the known steam pipe 1 for supplying steam to the soup pot The components are stacked so that the heat inside the steam pipe 1 is maintained to increase the efficiency of the steam pipe 1, prevent the steam pipe 1 from being exposed to the outside, and By not opening the gap, the possibility of injury to the user, such as burns, is minimized.

Referring to Figure 2 to 3 of the thermal insulation device of the steam pipe according to the present invention, the thermal insulation device, the first pipe 20 and the heat insulating material 35, the outer spring pipe ( 40) and the second pipe 50 are sequentially stacked, and the space between the first pipe 20 and the second pipe 50, that is, the heat insulating material 35, in a state in which both ends thereof are sealed with a support cap. And the outer spring pipe 40 is provided with a vacuum layer 60 formed so that the space in which the vacuum is formed to have a more effective thermal insulation insulation effect.

Specifically, the first pipe 20 is preferably made of a material such as stainless steel having excellent heat resistance and corrosion resistance to be configured in a cylindrical shape to surround the outer peripheral surface of the steam pipe 1, the diameter of the inner peripheral surface of the steam pipe It may be formed to be the same as the diameter of the outer circumferential surface of (1) to be in close contact, but if the contact is formed in this way the temperature of the first pipe 20 can be very high by the steam inside the steam pipe (1) In view of this, the diameter of the first pipe 20 is formed to be a certain level larger than the diameter of the steam pipe 1 so that the inner circumferential surface of the first pipe 20 is slightly spaced apart from the outer circumferential surface of the steam pipe 1 It is preferable to arrange as much as possible.

In this case, due to the difference in diameter between the space between the steam pipe 1 and the first pipe 20, that is, between the outer circumferential surface of the steam pipe 1 and the inner circumferential surface of the first pipe 20. A specific space is provided inside the first air layer 10 so that the air can be injected into the space through the air inlet provided at one side, and the first air layer 10 is the steam. The heat generated by the outer circumferential surface of the pipe 1 may be contained in the air molecules of the first air layer 10 to effectively insulate.

More preferably, the first air layer 10 has a density higher than that of general air in order to perform a more efficient thermal insulation function.

The first pipe 20 is more tightly coupled to the steam pipe 1 by using a sealing method by welding, so that the outer circumferential surface of the steam pipe 1 is spaced apart from the steam pipe 1 at regular intervals. The first air layer 10 formed therein may be sealed by a closing cap 80 to be described later, which will be described later with reference to the closing cap 80. Shall be.

The heat insulating material 35 is formed to surround the outer circumferential surface of the first pipe 20 to further enhance the heat retention of the steam pipe 1, and mixes glass wool to atherosine (rubber foaming agent) at a constant ratio. It means a known material or a heat insulating member made of each material.

The heat insulating material 35, so as to significantly lower the temperature of the residual heat conducted in the process of the heat of the steam pipe 1 is transferred to the first pipe 20 passing through the first air layer 10 to the outside. In addition to minimizing the risk of burns by the user, when the temperature of the first pipe 20 decreases due to a low external temperature, the steam temperature of the steam pipe 1 located inside the inner circumferential surface of the first pipe 20 is increased. Do not lower together below the reference temperature.

The heat insulating material 35 is generally fixed with a heat insulating tape such as a heat resistant adhesive tape, but in the heat insulation device of the steam pipe 1 according to the present invention, the outer spring pipe 40 as a fixing means of the heat insulating material 35. The outer spring pipe 40 has a shape of a spring and arranges the insulating material 35 inside thereof, thereby wrapping a portion of the outer circumferential surface of the insulating material 35 and pressing it toward the first pipe 20. Is formed to be able to fix the thermal insulation material (35).

The reason why the outer spring pipe 40 is provided as a means for fixing the insulating material 35 in the heat insulation device of the steam pipe 1 according to the present invention is that the insulating material 35 is made of the conventional insulating tape or the like. In the case of fixing the thermal insulation tape, the heat of the steam pipe (1) conducted to the insulating tape side due to long-term use accumulates, thereby causing damage to the adhesive of the thermal insulation tape, thereby reducing the adhesive force of the thermal insulation tape, thereby making the thermal insulation material 35 stable for a long time. This is to minimize the possibility of not being fixed, and to maintain a more stable fixed state by applying a greater pressure to the heat insulating material (35).

In particular, in the process of forming the vacuum layer 60 in the space provided with the heat insulating material 35 and the outer spring pipe 40, there is a possibility that the heat insulating material 35 can be deformed or compressed, and thereby detached to the outside. The main purpose is to reduce, which will be described later.

A second pipe 50 is formed on an outer circumferential surface of the heat insulating material 35 fixed to the first pipe 20 by the outer spring pipe 40, and the second pipe 50 is the heat insulating material 35. And is formed to surround the outer spring pipe 40 in a sealed state so that substances such as water or dust do not penetrate into the insulating material 35 unnecessarily, thereby increasing durability of the thermal insulation device of the steam pipe 1 according to the present invention. In addition to the basic role, the space in which the first pipe 20 and the second pipe 50 are spaced apart, that is, the space in which the heat insulating material 35 and the outer spring pipe 40 are formed may be formed in a sealed state. Provide a space in which layer 60 is formed.

In order to be able to remove all the air remaining in the vacuum layer 60, the second pipe 50 is provided with an air inlet which is connected to the outside on one side and can be opened and closed, the air inlet 61 A known air suction device is connected to allow the air remaining in the space spaced from the first pipe 20 and the second pipe 50 to be sucked to the outside so that the heat insulating material 35 and the outer spring pipe 40 The space with) may be provided with a vacuum layer 60 formed with a vacuum.

The vacuum layer 60 is a steam provided inside the steam pipe (1) at the same time as the heat insulating device of the steam pipe (1) according to the present invention does not conduct the heat conducted in the steam pipe (1) to the outside By the function of heat insulation and insulation so that the temperature does not fall by the external temperature, it is possible to perform the effect of heat insulation and insulation at the same time very efficiently and stably compared to performing only the effect of heat insulation in a state filled with air.

The second pipe 50 may be welded so that both ends are in contact with the steam pipe 1 to maintain a sealed state, but the process of bending and welding the second pipe 50 is complicated and cumbersome. In view of the above, by providing the support caps at both ends, the heat insulation device of the steam pipe 1 according to the present invention can be fixedly fixed to the outer circumferential surface of the steam pipe 1 more simply and firmly.

As shown in FIGS. 2 to 3, the support cap 70 has an inner circumference cap having a diameter corresponding to the diameter of the first pipe 20 so that both ends of the first pipe 20 are inserted into the support cap 70. 71 and the second pipe 50 in a state of being bent at an angle toward the inner circumference cap 71 side, that is, the first pipe direction, extending bent vertically outward from the protruding start end of the inner circumference cap 71. ) Extends to a side end of the second pipe 50 from the first bent portion 72 and the extended end of the first bent portion 72 extending to a portion provided with It comprises a second bent portion 73 formed to be short in length.

The reason why the first bent portion 72 is formed to be inclined to a predetermined level is to allow the support cap 70 to be more stably coupled to both ends of the second pipe 50, and the support cap 70 is formed in the vacuum layer 60. ) To increase the durability by more effectively withstanding the pressure applied to the support cap 70 due to the difference in air pressure between the vacuum layer 60 and the outside. The cap 70 is inserted into the inner circumference cap 71 so that the first pipe 20 penetrates, and then welds the extended end of the second bent portion 73 and the side end of the second pipe 50. In this way, the second pipe 50 can be sealedly coupled to the outer circumferential surface of the first pipe 20 to support the second pipe 50 and to form the vacuum layer 60 more stably. To be possible.

At this time, the inner circumference cap 71 of the support cap 70 may be welded to one side of the outer circumferential surface of the first pipe 20 in order to achieve a more stable coupling.

In addition, the support cap 70 only seals the vacuum layer 60 formed between the first pipe 20 and the second pipe 50, and thus the first pipe 20 and the steam pipe. Stable sealing of the first air layer 10 formed between (1) is problematic.

Of course, the first pipe 20 may be coupled to the steam pipe 1 in a sealing manner by welding as described above, but it may be insufficient in durability in order to completely seal the first air layer 10 by welding alone. In consideration of the fact that it can be, it is possible to further form a pipe closing cap for sealing the first air layer (10).

Referring to FIGS. 2 and 3, the closing cap 80 is formed on an outer side of the support cap 70, that is, on an opposite side of the side on which the first and second pipes are formed. The through hole 81 allows the steam pipe 1 to be inserted into a central portion of the disc having the same diameter as that of the second pipe 50, and the first hole around the through hole 81. And an insertion portion 82 extending vertically bent to the pipe 20 side. In this case, the insertion part 82 is inserted into a space between the first pipe 20 and the steam pipe 1, that is, a space in which the first air layer 10 is formed, thereby increasing the first air layer 10. It is to be sealed at the stage.

The closing cap 80 may be formed of a material having low thermal conductivity and thermoplasticity because the insert portion 82 is in direct contact with the steam pipe 1 and the temperature thereof may be very high.

At this time, both ends of the first and second pipes in which the closing cap 80 and the support cap 70 are formed have a higher temperature than other parts despite the low thermal conductivity and thermoplasticity of the material forming the closing cap 80. Although there will be no choice but to have the pipe closing cap 80 and the support cap 70 in close contact with each other, since the heat can be transferred to the second pipe 50, the closing cap 80 And the support cap 70 is filled with a non-conductor, such as rubber or silicon in the space to be provided with a predetermined level spaced apart so that the heat insulation device of the steam pipe 1 according to the present invention can be used more efficiently. can do.

To this end, a flange 90 may be further provided between the closing cap 80 and the support cap 70, the flange 90 extending with the insertion cap 91 as shown in FIG. 3. It is formed by including a portion 92, the insertion cap 91 is formed to protrude similarly to the inner circumference cap 71 of the support cap 70 so that the first pipe 20 can be fitted therein The outer side of the support cap 70, that is to be in contact with the start end of the first bent portion 72, the extension portion 92 of the portion in contact with the support cap 70 in the insertion cap 91 It extends in the vertical direction of the longitudinal direction of the said 1st pipe 20 from the opposite end (the protruding start end of the said insertion cap 91). The closing cap 80 and the support cap 70 may be spaced apart from each other by allowing the closing cap 80 to be mounted on the outside of the extension part 92, that is, of the support cap 70. The first bent portion 71 and the insertion cap 91 and the extension portion 92 to include a space forming a circumference.

As described above, the filler 95 formed of a material having low thermal conductivity such as silicon or rubber is inserted into the space between the closing cap 80 and the support cap 70 formed by the flange 90 to further improve thermal conductivity. Make it lower. The filler 95 may be formed to surround all of the closing cap 80 exposed to the outside to more securely protect the safety of the user.

In addition, when the heat insulating material 35 is in direct contact with the surfaces of the first pipe 20 and the second pipe 50, the heat insulating material (if used for a long time according to the characteristics of the material constituting the heat insulating material 35) The problem that the heat insulating effect is reduced by damaging the heat insulating material 35 due to a problem such as a portion of the contact with the first and the first and second pipes in 35) occurs.

In order to solve this problem, the heat insulating device of the steam pipe 1 according to the present invention is further provided with an inner spring pipe 30, the support 45 is further added to the inner and outer spring pipe (30, 40). The inner spring pipe 30 may be formed between the first pipe 20 and the heat insulating material 35 to surround the inner circumferential surface of the heat insulating material 35.

In this case, the inner and outer spring pipes 30 and 40 are both provided, and each of the spring pipes 30 and 40 further includes a support part 45 to be provided at a predetermined interval from the first and second pipes. It may be, the support portion formed on one side of the outer spring pipe 40, so as to be fixed in a state spaced apart from the second pipe, each simply on one side of the outer spring pipe 40 It may be configured by having a bar protruding toward the second pipe, but since the structure has a limit in durability and bearing capacity, the support portion 45 in the heat insulation device of the steam pipe 1 according to the present invention. ) May be configured so that the diameter of one portion of each of the outer spring pipe 40 is larger than the diameter of the other portion.

That is, the support part 45 is formed in the outer spring pipe 40 of the shape similar to that of a material such as an elongated wire deformed in a cylindrical shape, formed in several places the diameter is larger than the other parts to the outer spring It is formed along the circumference at a certain portion of the pipe 40.

The support part 45 formed on the outer spring pipe 40 protrudes to contact the surface of the second pipe, and the other part is spaced apart from the surface of the second pipe in a state supported by the support part 45. In addition to being able to be stored, the area of the vacuum layer 60 can be formed to be wider, so that more efficient heat insulating effect can be expected. In addition, even when all the remaining air is discharged to the air inlet to form the vacuum layer 60, the possibility that the insulating material 35 can be separated is also greatly reduced.

The support 45 may be formed to be spaced apart from the first pipe in such a manner that one portion of the inner spring pipe 30 is smaller in diameter than the other portion.

Even with the above configuration, it is possible to effectively achieve the basic purpose of the heat insulating device according to the present invention. The second pipe may further include a hollow tube 51, a buffer tube 52, and an impact absorbing member 53.

Figure 4 is a cross-sectional view showing a longitudinal section of the heat insulation device of the steam pipe according to the present invention.

Referring to FIG. 4, the hollow tube 51 is formed to have a hollow space at a portion inside one side of the circumferential surface of the second pipe, that is, between the inner circumferential surface and the outer circumferential surface of the second pipe, and extend to a predetermined length. The direction of the hollow tube 51 is formed in the longitudinal direction from one end to the other end in the longitudinal direction of the second pipe.

 The hollow tube 51 is provided to solve the problem that the second pipe can be easily damaged by a relatively small impact because the inside of the second pipe is formed of a vacuum layer, and the second pipe is made of stainless steel. By forming a plurality of hollow pipes 51 in the pipe, the impact transmission medium can be increased to disperse the impact.

The hollow tube 51 is preferably formed to have a square longitudinal section in consideration of the coupling with the buffer tube 52 and the shock absorbing member 53 to be described later.

A buffer tube having a shape different from that of the hollow tube 51, preferably in the shape of a longitudinal cross section, so that the hollow tube 51 may be accommodated in the hollow tube 51 by fitting. And a 52, one side of the buffer tube 52 is configured to be in contact with one side of the side wall of the hollow tube 51 in order to more easily disperse the external impact to reduce unnecessary flow. It is desirable to be.

The buffer tube 52 may be configured to be made of the same material as the second pipe, but preferably, the buffer tube 52 is formed of a material having less rigidity than that of stainless steel so that the impact can be more easily dispersed. When the buffer pipe 52 is formed to have a density and rigidity different from that of the material of the second pipe, when the external shock is transmitted from the second pipe to the buffer pipe 52, the wave is changed so that the shock value is constant. Has the effect of being able to be reduced in size.

The buffer pipe 52 is made of a material having a stronger elasticity than the second pipe and the buffer pipe 52 so as to not only disperse the impact more easily, but also to be more firmly maintained in vibration due to the impact, The shock absorbing member 53 is formed to have a volume smaller than that of the buffer tube 52 and is accommodated in the buffer tube 52. The shock absorbing member 53 is most preferably made so that the longitudinal section has a triangular shape, which means that the one or three corners of the shock absorbing member 53 in the hollow tube 51 is buffered. It has a structure that is in contact with or attached to the inner wall of the pipe 52 to have a stable structure. The shock absorbing member 53 formed as described above not only does not flow unnecessarily in the buffer tube 52, but also maintains a firmly fixed state and secures a stable space in which the volume does not change. to provide.

As described above, after the hollow pipe 51, the buffer pipe 52, and the shock absorbing member 53 are further provided inside the second pipe, the second pipe may be damaged in order to minimize damage of the second pipe due to external impact. The buffer member 54 is inserted into the remaining space in which the buffer tube 52 is accommodated in the hollow tube 51, and in the remaining space in which the shock absorbing member 53 is accommodated in the buffer tube 52. A second air layer 55 is formed through which compressed air is injected so that the density of the air is large.

The shock absorbing material 54 is made of a soft material such as silicon or rubber to disperse the impact applied from the outside of the second pipe, and the second air layer 55 is made of high density condensed air. In addition to the dispersion of the steam pipe (1) to be able to insulate and insulate the heat conducted once more.

When the external force acts on the second pipe by the above-described configuration, when the external force extends to the hollow tube 51 through the surface of the second pipe, the buffer member 54 primarily buffers the buffer member 54. Thereafter, after the shock is dispersed in the buffer tube 52, the shock is absorbed in the second air layer 55, and finally, the shock transmitted from the shock absorbing member 53 is finally absorbed. It is possible to provide up to five orders of impact absorption in the second pipe. As a result, when the shock is applied to the second pipe, which is constantly under constant air pressure from the outside due to the vacuum layer, the shock can be appropriately absorbed several times.

In addition, a third pipe 100 is further formed in the heat insulation device of the steam pipe to allow the user to visually sense the temperature of the surface of the heat insulation device, and at the same time, to more effectively prevent a user's burn. Can be.

Referring to FIG. 4 again, the heat insulation device of the steam pipe according to the present invention is formed to surround the outer circumferential surface of the second pipe, but a plurality of grooves formed in a predetermined depth inward from the surface to the inner circumferential surface from one side of the outer circumferential surface ( A third pipe 100 with 101 may be further provided.

The third pipe 100 is formed to surround the outer circumferential surface of the second pipe, as shown in FIG. 4, primarily to insulate the steam pipe 1, and the groove 101 described above. The second thermal insulation effect and the user to simultaneously grasp the surface temperature of the thermal insulation device by the provided is provided.

The cover 101 is made of a flexible material around the opening of the groove 101 in a state where a plurality of grooves 101 are formed on the surface of the third pipe 100 to shield the inside of the groove 101. 102 is attached to the bar, the stretch cover 102 is made of a material such as latex used in a known balloon, etc. in such a way that the perimeter of the stretch cover 102 is attached to the periphery of the opening of the groove 101 Is formed.

The third air layer 103 filled with a predetermined density is formed in the groove 101 shielded by the stretchable cover 102, and the air molecules contained in the third air layer 103 are formed in the third air layer 103. The volume of the pipe 100 is changed according to the extent to which the pipe 100 is heated by the steam pipe 1 to apply pressure to the stretch cover 102 so that the stretch cover 102 can be stretched.

That is, when the volume of the third air layer 103 is increased by the heat conducted to the third pipe 100, the expansion cover 102 swells upward and has a shape like embossing. When the amount of heat conducted to the third pipe 100 is insufficient and the volume of the third air layer 103 decreases, the expansion cover 102 sinks downward (that is, to the inner side of the groove 101). will be.

When the third pipe 100 is heated to cause the expansion cover 102 to swell, the user may notice that the third pipe 100 has been heated visually and not only pay attention, but also accidentally. Even if the user's skin comes into contact with the outside of the third pipe 100, the elastic cover 102 protrudes, thereby preventing direct contact with the surface of the third pipe 100, thereby minimizing the user's image.

At this time, the amount of air molecules contained in the third air layer 103 is, in general (that is, even when the third pipe 100 is not heated above a certain temperature) in a state where the stretch cover 102 is stretched to a certain level. The density of air molecules may be greater than that of outside air to maintain the

Figure 5 is a flow chart illustrating a schematic procedure for a method for constructing a heat insulation device of the steam pipe according to the present invention.

Referring to the embodiment of the important configuration of the heat insulation device of the steam pipe 1 according to the present invention with reference to Figure 5, the heat insulation device is constructed by sequentially stacking each configuration in the steam pipe (1) First, the first pipe 20 is welded to a portion of the steam pipe 1 exposed to the outside. In this case, as described above, the first pipe 20 should be attached to be formed at a small distance from the outer circumferential surface of the steam pipe 1.

Thereafter, the inner spring pipe 30 is laminated on the outer circumferential surface of the first pipe 20, and the insulating material 35 is laminated thereon, and the second pipe 50 is then laminated on the outer circumferential surface of the insulating material 35. The outer spring pipe 40 can be fixed in such a manner as to be laminated on it.

In this case, for ease of construction, the inner and outer spring pipes 30 and 40 may be laminated so as to surround the outer circumferential surface of the first pipe 20 integrally in a pre-coupled state with the heat insulating material 35.

In the process of mounting the second pipe 50 on the outer circumferential surface side of the outer spring pipe 40, the air inlet 61 may be formed, and the air inlet 61 may include the second pipe ( It is preferably provided on one side of 50) to be opened and closed with the outside.

Thereafter, the inner spaces of the first and second pipes are sealed by welding the support caps 70 at both ends of the components, respectively, and then the first and second pipes are used by using the air inlets 61. The air remaining in the inner space of the discharged to the outside to form a vacuum layer (60).

At this time, it is preferable to allow all of the air molecules to disappear in the vacuum layer 60, but in this case, the first and second pipes and the heat insulating material 35 and the inner and outer spring pipes 30 and 40 are deformed by external pressure. As many as possible, it may be configured to leave only a very small amount of air in the vacuum layer 60 as needed.

Next, the flange 90 is inserted into the outer side of the support caps 70, that is, both end sides of the configuration, and the closing cap 80 is welded to the outer side of the first pipe 20. And the space between the steam pipe (1).

Thereafter, an air inlet of the first air layer 10 is formed, and the air inlet may be formed at one side of the insertion part 82 of the closing cap 80. Since the air is injected into the first air layer 10 through the air inlet, the air injection method is a well-known technique using a piston or a pump, and thus description thereof is omitted.

In this case, it is preferable to use air condensed at a predetermined temperature or less, so that a large amount of air molecules can perform a more stable buffer function, and more specifically, even at low temperatures It is preferable to use air of minus 10 to 3 ° C. as dry air from which moisture is removed so as not to occur.

Thereafter, the filler 95 is inserted into the spaced space between the support cap 70 and the closing cap 80, thereby completing the construction method of the thermal insulation device of the steam pipe 1 according to the present invention.

As described so far, the configuration and operation of the heat insulation device of the steam pipe and the construction method using the same have been described in the above description and the drawings. Without being limited, various changes and modifications are possible without departing from the technical spirit of the present invention.
