Abstract

PURPOSE:To simply construct heat-insulating installations, by providing face- shaped heaters around a pipe and by providing a heat-insulating material around each of the face-shaped heaters. CONSTITUTION:A face-shaped heater 5 formed by providing a vinyl sheet on each side of a face-shaped heat-producing layer is stuck on the inside of a heat insulating material 3 in semicylindrical shape, and thus a heat-insulating installation 1 is formed. The heat-insulating installations 1 in the semicylindrical shape are installed from on both sides of a pipe 7. Therefore, since a plumber has only to put the heat-insulating installations 1 around the pipe 7, the plumber can simply construct the heat-insulating installations 1. Furthermore, the function of the face-shaped heater 5 is not lost even if the face-shaped heater 5 is cut at any position, and hence the face-shaped heater 5 can be easily wrought at a construction site.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to heat insulation equipment for piping.

[0002]

2. Description of the Related Art Heretofore, for a pipe for flowing a liquid whose viscosity is increased at a low temperature or a liquid which is not preferable to be frozen at a low temperature, the pipe is kept warm as follows.

In the example shown in FIG. 4, a heat insulating material 103 is provided around the pipe 101 to make it less susceptible to the outside air temperature.

In the example shown in FIG. 5, a heat insulating material 203 is provided around the pipe 201, and the steam pipe 2 is provided inside the heat insulating material 203.
No. 05 is provided so that steam or hot water may flow in the steam pipe 205.

In the example shown in FIG. 6, a heating wire 303 is wound around the pipe 301, and a heat insulating material 305 is further provided to heat the heating wire 303 to raise the temperature of the pipe 301.

[0006]

However, such a heat retaining method has the following problems. In the example shown in FIG. 4, the heat insulating material 103 is as thick as 10 to 20 cm, the piping space is large, and the piping rack for supporting the piping 101 is large. In the example shown in FIG. 5, a facility for producing and circulating steam or hot water is required. In the example shown in FIG. 6, if the heating wire 303 is not arranged sufficiently densely, only a part of the pipe 301 will be heated, and if the fluid inside the pipe is to be heated on average, it will be heated more than necessary. There is a need.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a heat insulation facility for pipes which is easy to construct and consumes less electric power.

[0008]

In order to achieve the above-mentioned object, the present invention is characterized in that a planar heating element is provided around the piping and a heat insulating material is provided around the planar heating element. It is the heat insulation equipment.

[0009]

In the present invention, the heat of the sheet heating element is maintained to keep the piping warm.

[0010]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a perspective view of a heat insulation facility for piping according to an embodiment of the present invention. The heat insulation equipment 1 is one in which a planar heating element 5 is attached inside a semi-cylindrical heat insulating material 3.

FIG. 2 is a side view of the pipe 7 provided with the heat insulation equipment 1, and FIG. 3 is a sectional view taken along line AA of FIG. As shown in FIGS. 2 and 3, the heat insulation equipment 1 shown in FIG. 1 is attached around the pipe 7. In this case, the semi-cylindrical heat insulation equipment 1 shown in FIG. 1 is attached from both sides of the pipe 7.

The sheet heating element 5 is a sheet heating layer provided with vinyl sheets on both sides. An electric current is supplied to the heat generating layer via the lead wire to generate heat. This sheet heating element 5
Has a sheet shape, is highly flexible, and generates heat even when cut at any position.

As described above, the sheet heating element 5 is provided around the pipe 7.
The heat insulation equipment 1 having the above is provided to heat the pipe 7 by generating heat at a necessary time.

In the heat insulation equipment 1, the sheet heating element 5 is the heat insulating material 3.
Since the heat insulation equipment 1 is attached in advance to the circumference of the pipe 7 by the same method as the conventional one, the construction is simple. Since the planar heating element 5 does not lose its function even if cut at an arbitrary position, it can be processed at the construction site according to the length of the pipe, and the construction is easy. Further, since the pipe 7 can be heated in a planar shape, the power supply can be reduced as compared with the case where the heating wire 303 shown in FIG. 6 is arranged in a planar shape.

[0015]

As described above in detail, according to the present invention, it is possible to provide a heat insulation facility for piping which is simple to construct and consumes less power.
