FIG. 2 is a perspective view of a first divided body 100 constituting a heat insulating apparatus 500 for a pipe shown in FIG.

Hereinafter, the longitudinal direction means the same direction as the longitudinal direction of the pipe or valve unit, and the width direction means the circumferential direction of the pipe or the same direction as the width direction of the pipe.

1 to 5, a piping insulation device 500 according to an embodiment of the present invention includes a structure in which a plurality of divided bodies 100 and 200 are removably assembled to enclose a pipe (not shown) I have.

1 to 5, the first divided body 100 and the semicircular second divided body 200 are assembled by assembling the semi-circular heat insulating device 500, And a plurality of second split bodies 200 may be provided so as to have an arc-shaped structure.

Hereinafter, a case will be described in which the first divided body 100 having a semicircular section and the second divided body 200 having a semicircular section are assembled to constitute the heat insulating apparatus 500 for a pipe.

Each of the first divided body 100 and the second divided body includes an inner heat insulating layer 150a, an outer heat insulating layer 150c disposed in an outer diameter direction of the inner heat insulating layer 150a, And an intermediate heat insulating layer 150b disposed between the external heat insulating layers 150c.

The outer surface of the first divided body 100 is protected by the first closed cover 130 and the outer surface of the second divided body 200 is protected by the second closed cover 230.

A heat insulating material having different heat resistance may be applied to the inner heat insulating layer 150a, the intermediate heat insulating layer 150b, and the external heat insulating layer 150c.

A heat insulating material may be applied to the inner heat insulating layer 150a in such a manner that heat resistance gradually decreases toward the intermediate heat insulating layer 150b and the external heat insulating layer 150c or the heat insulating material may be applied to the intermediate heat insulating layer 150b and / The heat insulating material may be applied to the outer heat insulating layer 150c so that the heat resistance gradually increases.

For example, the inner heat insulating layer 150a is applied with a heat insulating material having a first heat resistance, and the intermediate heat insulating layer 150b is applied with a heat insulating material having a second heat resistance degree, which is lower than the first heat resistance degree And the outer heat insulating layer 150c may be provided with a heat insulating material having a third heat resistance which is lower than the second heat resistance. Alternatively, a heat insulating material having a third heat resistance may be applied to the inner heat insulating layer 150a, a heat insulating material having a second heat resistance may be applied to the intermediate heat insulating layer 150b, May be applied.

Generally, it is known that the higher the heat resistance, the higher the price for a high temperature (for example, 1000 ° C or higher), while the insulation performance is relatively low. In addition, it is known that insulation materials which can be used for low temperature (for example, 350 ° C or less) are relatively inexpensive because they have relatively low heat resistance, so that they are economical and excellent in heat insulation performance.

As a result, when a heat insulating material having a relatively high heat resistance is applied to the entire interior heat insulating layer 150a, the intermediate heat insulating layer 150b, and the external heat insulating layer 150c, there is a problem that the heat insulating performance is lowered and the manufacturing cost is increased In the case where a heat insulating material having a relatively low heat resistance is applied to the entire interior heat insulating layer 150a, the intermediate heat insulating layer 150b and the external heat insulating layer 150c, it is economical and can improve the heat insulating performance. However, It is difficult to apply the present invention to piping.

In order to overcome such a problem and to provide an economical heat insulating device with excellent heat insulating performance, in the case of a pipe requiring a high temperature and maintaining high temperature, the inner heat insulating layer (the portion adjacent to the pipes 21, A heat insulating material having a first heat resistance (for example, 700 to 1300 ° C) is applied to the intermediate insulating layer 150a and a heat insulating material having a second heat resistance (for example, 400 to 650 ° C) And the external heat insulating layer 150c may be applied with a heat insulating material in a range of a third heat resistance (for example, 100 to 350 占 폚).

Examples of the heat insulating material applied to the inner heat insulating layer 150a include cerak-wool having a heat resistance of 1200 to 1300 占 폚 and a thermal conductivity of 0.16 W / mk / 600 占 폚, (E-class fiber) having a thermal conductivity of 0.06 W / mk / 400 DEG C and an example of the heat insulating material applied to the intermediate insulating layer 150b is a material having a heat resistance of 600 to 650 DEG C and a thermal conductivity of 0.069 W Examples of the heat insulating material applied to the external heat insulating layer 150c include glass wool having a heat resistance of 300 to 350 占 폚 and a thermal conductivity of 0.032 W / mk / 20 占 폚. (glass-wool).

As a result, in the case of a piping requiring high temperature maintenance, a high-temperature insulating material is used for the internal heat insulating layer 150a adjacent to the piping so as to function only for primarily lowering the high temperature, The intermediate insulation layer 150b can be economically installed and maximized the insulation performance at an intermediate temperature at which the temperature is lowered by the inner insulation layer 150a and the intermediate insulation layer 150b is formed using the insulation layer for intermediate temperature, 150a which is the last part of the heat insulating layer 150a having a lower temperature by the intermediate insulating layer 150b and the intermediate insulating layer 150b can be applied to the external insulating layer 150c. In the case of piping requiring low-temperature maintenance, it is possible to apply the present invention to the case of piping that requires maintenance at a high temperature and vice versa. Here, the heat resistant temperature range of the first heat resistance degree, the second heat resistance degree and the third heat resistance degree can be variously changed corresponding to the temperature of the pipe.

The heat insulating materials applied to the inner heat insulating layer 150a, the intermediate heat insulating layer 150b, and the external heat insulating layer 150c have micropores. That is, the ceramic, the class fiber, the mineral wool, the glass wool, etc. have micropores inside.

However, in the present invention, in order to improve the heat insulating performance, the air filled in the micro-pores is removed and an inert gas such as argon gas (Ar) or krypton gas (Kr) Insulation performance can be improved by injecting into the cavity. The inert gas such as argon gas is stable and the thermal conductivity is lower than that of air, so that the heat insulating performance can be improved.

The inert gas may be injected into the microvoids by using a quick coupler or the like to form the internal heat insulating layer 150a, the intermediate heat insulating layer 150b, and the external heat insulating layer 150c in a vacuum state, By injection. Other methods well known to those of ordinary skill in the art may be used.

The inner heat insulating layer 150a, the external heat insulating layer 150c, and the intermediate heat insulating layer 150b may be surrounded and protected by a heat insulating material protecting layer 154. The heat insulating material protection layer 154 may be formed to individually surround the inner heat insulating layer 150a, the external heat insulating layer 150c and the intermediate heat insulating layer 150b, The heat insulating layer 150c, and the intermediate heat insulating layer 150b may be enclosed in a single protective layer. And may have a double protective layer structure of a first heat insulating protective layer which is individually wrapped and a second heat insulating protective layer which surrounds the whole.

The heat insulating material protection layer 154 may be formed in close contact with the inner heat insulating layer 150a, the external heat insulating layer 150c, and the contact surface with the intermediate heat insulating layer 150b.

The heat insulating material protection layer 154 may be any material having a gas-impermeable material, but may have a material such as a fabric coated with a gas-impermeable material. Fabrics and the like are known as fibers having a special material for heat resistance.

The reason why the heat insulating material protection layer 154 is coated with the gas impermeable material is that the inert gas filled in the micro vacancies of the internal heat insulating layer 150a and the external heat insulating layer 150c and the inert gas filled in the internal space of the intermediate heat insulating layer 150b So that the gas does not leak to the outside.

Since the heat insulating material protection layer 154 is formed on a curved surface such as an inner diameter surface of the inner heat insulating layer 150a and an outer diameter surface of the outer heat insulating layer 150c, it is difficult to form the heat insulating material in close contact with a curved surface. For this purpose, the heat insulating material protection layer 154 may be formed so as to closely contact the curved surface by sewing a plurality of fiber pieces. In this case, however, the inert gas may leak out through the seam.

In order to prevent this, it is possible to form the heat insulating material protective layer 154 by joining the plurality of fiber pieces with a heat sealant or the like instead of sewing them. Alternatively, it is possible to form the curved surface of one fiber, fold the remaining portion, and join the folded portion with a sealant or the like to form the heat insulating material protection layer 154. Alternatively, after the plurality of fiber pieces are sewn to form the heat insulating material protection layer 154 so as to be in close contact with the curved surface, it is possible to seal the inside of the seaming portion with heat resistant sealant tape.

The first finishing cover 130 or the second finishing cover 230 is disposed on the outer surface of the outer protective layer 150c and is made of a metal material and is formed of the inner insulating layer 150a, The heat insulating layer 150c and the like can be stably protected or maintained.
