DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for beautifully dressing the surface of a valve or a flange connected to a pipe.

[0002]

2. Description of the Related Art The surface of a pipe through which a heated or cooled fluid passes and a valve and a flange connected to the pipe are covered with a heat insulating material. This is because the pipes and valves are insulated to reduce heat loss or to prevent dew condensation on the valves and flanges. As the heat insulating material, glass fiber, rock wool, or the like is often used.

A heat insulating material in which inorganic fibers such as glass fibers are densely assembled is inexpensive, has excellent heat resistance, and has excellent heat insulating properties. However, since the fibers appear on the surface, the surface cannot be finished cleanly. For this reason, it is necessary to fix and cover the surface of the heat insulating material with a decorative cover. An adhesive decorative tape having an aluminum foil adhered to the surface is used as a surface decorative cover for piping. The piping can be beautifully dressed by wrapping an adhesive decorative tape around the surface of the heat insulating material. However, since the bulb and the flange have a complicated shape with irregularities, it is extremely troublesome to cover with a pressure-sensitive adhesive tape. In addition, there is a disadvantage that the adhesive decorative tape cannot be coated cleanly.

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate a surface decorative cover of piping for embodying the technical idea of the present invention, and the present invention does not specify the surface decorative cover as follows.

Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

A typical example in which a surface decorative cover covers a valve or a flange connected to a pipe is shown in FIGS. FIGS. 1 and 2 show the surface decorative cover of the flange,
3 and 4 show a cosmetic cover for the valve. FIG. 1 shows a surface decorative cover of the flange 11 at a connection portion of the pipe 2, and FIG. 2 shows a surface decorative cover of the flange 11 for closing an end of the pipe 2. The surface decorative cover of the valve shown in FIGS. 3 and 4 covers the entirety of the valve 10 except for the handle 10A, and then coats the heat insulating material 3 to expose the handle 10A of the valve 10 to the outside. ing.

The surface decorative cover shown in FIGS.
It is manufactured by processing a sheet material 1 in which a topsheet 7 is adhered to the surface of a paperboard 4, and a suitable topsheet 7 is a net material 5 laminated with an aluminum foil 6. The surface decorative cover shown in the figure has a tubular portion 12 of a sheet material 1 which is curved and formed into a tubular shape which covers the outer peripheral surfaces of a valve 10 and a flange 11 covered with a heat insulating material 3, and both ends of the tubular portion 12. And an end surface closing portion 13 of the sheet material 1 whose surface is closed. Further, the sheet material 1 can be provided with a waterproof layer 18 such as a plastic sheet laminated on the inner surface of the paperboard 4 to improve water resistance.

The paperboard 4 of the sheet material 1 used for the cylindrical portion 12 and the end surface closing portion 13 contains waste paper pulp as fibers in an amount of 50% by weight or more of the whole fibers in order to reduce manufacturing costs. Recovered paper pulp is produced using waste paper generated in the paper manufacturing process and recovered paper obtained by collecting waste paper once used as paper. Used paper pulp is produced by disintegrating and deinking used paper. Recovered paper pulp can be produced at low cost, although the strength of the paper is low, since the fibers are cut short.

The paperboard 4 uses 50 to 100% by weight of waste paper pulp as a fiber, more preferably 55 to 9%.
5% by weight, more preferably 60-90% by weight of waste paper pulp is used as fibers. The paperboard 4 produced by increasing the amount of waste paper pulp can be made inexpensive by reducing raw material costs.

However, since the waste paper pulp has short fibers, the strength of the paperboard 4 decreases as the content increases.
In addition, when curved into a cylindrical shape, the polygonal line becomes more conspicuous. If the amount of waste paper pulp for producing base paper is reduced and a large amount of long synthetic fibers are added, the bending strength of the paperboard 4 in the longitudinal direction is improved, and the number of broken lines can be reduced. Therefore, in the sheet material 1 used for the surface decorative cover of the present invention, the content of the used paper is set to an optimum value in consideration of these points.

As the paperboard 4, a homogeneous chip ball or a white chip chip ball is used. Paperboard 4 that is a chip ball
Is to use waste paper pulp with a round paper machine and reduce the thickness from 0.5 to
It is 2 mm, preferably 0.8 to 1.5 mm. For homogeneous chip balls, each layer is made of the same raw material,
The white-backed chipball uses upper white paper pulp on the back side. In the white back chip ball, a net material 5 and an aluminum foil 6 are laminated and adhered to a white surface on the back surface.

Further, the thickness of the paperboard may be 0.5 to 2 mm, preferably 0.8 to 1.5 mm instead of the chip ball.
mm paperboard can also be used. White paperboard is manufactured by laminating a surface paper made of bleached chemical pulp with a layer of waste paper pulp.

On the surface of the paperboard 4, a surface sheet 7 in which a net material 5 and an aluminum foil 6 are laminated is adhered. The mesh material 5 reinforces the paperboard 4, and the aluminum foil 6 beautifully decorates the surface of the pipe 2 and reflects heat to improve the heat insulating property. The aluminum foil 6 is adhered to the surface of the net material 5 and formed into a shape along the surface of the net material 5, that is, a surface shape having countless irregularities instead of a mirror surface.
The irregularities of the aluminum foil 6 are provided according to a certain rule,
The surface is beautiful.

The sheet material 1 is formed by bonding a net material 5 to the surface of the paperboard 4 and further bonding an aluminum foil 6 on the net material 5. Further, it can be manufactured by bonding an aluminum glass cloth, which is obtained by laminating a net material and an aluminum foil. Aluminum glass cloth is commercially available as a material obtained by bonding an aluminum foil to the surface of a mesh material obtained by lattice-braiding glass fibers. The aluminum glass cloth is formed by thinly assembling glass fibers into a wire, and braiding the wire into a lattice to form a net. A surface decorative cover in which an aluminum glass cloth is adhered to the surface of a paperboard can be made extremely strong by being reinforced with glass fibers. Also, it can be easily manufactured by bonding aluminum glass cloth to the surface of paperboard.

However, in the surface decorative cover of the present invention, the net material used for the surface sheet 7 is not specified to glass fiber. For example, as shown in FIG. 5, a belt-shaped plastic film 5A is braided in a lattice to form a thin sheet-like net material 5, or as shown in FIG. 6, the plastic film 5A and the plastic fiber 5B are combined. A mesh material 5 braided in a mesh shape can also be used. The net material 5 of FIG. 6 is bonded to the paperboard 4 so as to bend in the direction indicated by the arrow in the figure. further,
As shown in FIG. 7, a mesh material 5 in which a plastic wire, glass fiber, carbon fiber, thin metal fiber, or the like is braided in a lattice shape can also be used.

On the surface of the paperboard 4, a net 5 and an aluminum foil 6 are bonded as a surface sheet 7 via an adhesive. After laminating and bonding the paperboard 4, the net material 5, and the aluminum foil 6, the sheet material 1 is curved into a cylindrical shape by passing between the rolls 8 as shown in FIG. Sheet material 1
It is formed into a cylindrical curve in a direction along the outer circumference of the bulb 10 and the flange 11 covered with the heat insulating material 3.

Ideally, the radius of curvature to be curved is equal to the outer diameter of the heat insulating material 3 covering the outer periphery of the valve 10 and the flange 11. However, in the surface decorative cover of the present invention, since the end surface closing portions 13 are connected to both ends of the curved tube portion 12, the cylindrical portion 12 can be kept in a curved shape by the end surface closing portions 13. Therefore, the radius of curvature curved by the roll 8 is set to a shape that can easily connect the end face closing portion 13.

In the apparatus shown in FIG. 8 for bending the sheet material 1 into a cylindrical shape, a belt 9 is hung on a roll 8, and the sheet material 1 is pinched and curved by the belt 9 and the roll 8. This device has a feature that the sheet material 1 can be smoothly curved to a small radius of curvature and formed into a cylindrical shape. In addition, this device can freely change the radius of curvature for bending by changing the position of the roll 8.
