[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a heat insulating cover around a valve, which covers a valve interposed in a pipe of a plant or the like to prevent heat radiation from the valve and save energy.

[0002]

[Prior art]

 FIG. 16 shows a view in which a valve 10 is interposed between a pipe 1 and a pipe 2 used in a plant or the like, and flanges 3 and 4 formed at ends of the pipes 1 and 2 and a valve 10 are shown. The flanges 11 and 12 formed on both sides are joined together and connected with bolts and nuts (not shown). A handle 13 is provided above the valve 10 for opening and closing an internal bumper and the like to adjust the flow path, and to control opening and closing such as opening and closing. Reference numeral 14 denotes a handle shaft.

In a plant or the like, the temperature of the fluid in the pipes 1 and 2 is high, and a heat insulating cover 15 is provided around the pipes 1 and 2 as shown in FIG. I'm wearing However, since the tip of the cover 15 and the entire valve 10 are exposed, heat is radiated from the non-covered portion, which poses a problem of energy saving. In particular, since a large number of valves 10 are used in a plant, the loss due to heat radiation of the entire plant is large.

[0004]

[Problems to be solved by the invention]

 Therefore, conventionally, a heat insulating cover that covers the periphery of the valve 10 has been provided, but there have been various problems. That is, the conventional heat insulating cover has a substantially square shape without considering the irregularities around the valve 10 and merely covers the end portions of the valve 10 and the cover 15, and furthermore, connects both sides through a cord. Because of this structure, the appearance was poor as a whole, and it took a long time to attach the heat insulating cover, and the workability was poor.

Another conventional heat retaining cover has a substantially cylindrical shape, and is attached around the valve 10 by making the diameter of a portion of the valve 10 different from a diameter of a pipe portion from a flange. is there. Although this thermal cover is good in appearance, it uses a thermal cover having a size corresponding to each size of the valve 10. There are many types and sizes of the valves 10, and even the same type of valve 10 has different dimensions and diameters between the flanges 11 and 12 if the manufacturer is different. In particular, valves other than globe valves have their own shapes. Therefore, after listening to the type and dimensions of the valve 10 to be used, the material of each member is cut to just fit the size, and the cut member is sewn to form a heat insulating cover.

[0006] Therefore, inventory management is difficult, and even when inventory management is performed, it is necessary to store a large number of types of inventory, which is very troublesome and promptly responds to users. There was a problem that it was not possible. Furthermore, there is a problem that even if a user places an order for the above-mentioned reason, the delivery date is delayed.

[0007] The present invention has been made in view of the above points, and has a beautiful appearance and a design effect. In addition, even if the dimensions are slightly different, the valve can be fitted around the valve well. Moreover, it is intended to provide a heat insulating cover around the valve which can be quickly mounted.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded plan view of the heat insulating cover 20 of the present invention. Basically, the heat insulating cover 20 is basically connected to both sides of the main body cover 21 by suturing so as to be movable in the lateral direction. It is composed of a pair of side covers 22 and 23 and a pair of neck covers 24 and 25 which are integrated by sewing at substantially the center portions of both ends of the main body cover 21.

First, the configuration of the main body cover 21 will be described. As shown in FIG. 2, which shows a cross-sectional view of the main body cover 21, the outer shell of the main body cover 21 has a flat outer sheet 30 and a flat inner sheet 31. And is formed in a bag shape. The inside of the bag-shaped main body cover 21 is filled with a heat insulating material 32.

The outer sheet 30 and the inner sheet 31 constituting the outer shell of the main body cover 21 are made of the same material, for example, a flexible and flame-retardant silicon-coated cloth. The heat insulating material 32 uses, for example, glass wool. These materials themselves are well known, and it goes without saying that the materials are appropriately changed according to the operating temperature conditions of the heat retaining cover 20 and used.

Since the shape of the heat insulating cover 20 is made substantially cylindrical when the heat insulating cover 20 is mounted on the valve, the outer sheet 30 has a larger area than the inner sheet 31. Then, the outer sheet 30 and the inner sheet 31 are stitched together at their peripheral edges. In this case, as shown in FIG. Sew with a sewing machine at the point. Of course, the material of the thread to be sutured is flame retardant. The edging member 28 is stitched on each side of the main body cover 21. The heat insulating material 32 is filled before the last side is sewn by the edging member 28, and then the edges of the outer sheet 30 and the inner sheet 31 are sewn by the edging member 28. The edge of the outer sheet 30 may be folded back toward the inner sheet 31 and stitched.

The edging member 28 is made of the same material as the outer sheet 30, and the member is turned over and used as the edging member 28. In such a case, the surface of the outer sheet 30 is silver, but the color of the back is white or milky white.

As shown in FIG. 1, a substantially arc-shaped concave portion 33 is formed at the center of both ends of the main body cover 21, and a substantially fan-shaped connection piece 34 is formed along the edge of the concave portion 33. One edge is connected by stitching. The connecting piece 34 is made of the same material as the outer sheet 30 and has flexibility. Further, the other edge of the connection piece 34 and the ends of the neck covers 24 and 25 are connected by sewing.

On both sides of the inner sheet 31 of the main body cover 21, connecting pieces 35 each having a substantially V-shaped cross section as shown in FIGS. 1 and 7 are integrally formed. The connection piece 35 will be described later. The connecting pieces 35 are formed along both ends of the body cover 21, one end of the connecting piece 35 is integral with the inner sheet 31, and the other end of the connecting piece 35 is a free end. The free ends of the connecting pieces 35 and the side covers 22 and 23 are integrally connected by stitching.

As shown in FIG. 1, hooks 36 are mounted on the left and right sides of one end of the main body cover 21, and a hook 40 paired with the hook 36 is provided on the other side of the main body cover 21. It is attached to each of the left and right ends.

Next, a method for forming the connecting piece 35 will be described. The inner sheet 31 of the main body cover 21 is a sheet having flexibility. Therefore, as shown in FIG. 6, a folded portion 50 is formed in the middle of the inner sheet 31. Bend at the middle part of the direction to make the cross section substantially V-shaped. Then, by suturing at the locations indicated by a, b, and c in the figure, the connection piece 35 having the flattened portion of the folded portion 50 as shown in FIGS. 1 and 7 is integrally formed with the inner sheet 31. I have to.

The free ends of the connecting pieces 35 formed as described above are sewn to the ends of the side covers 22 and 23 as shown in FIG. It is formed integrally with the main body cover 21. Here, the side covers 22 and 23 can freely project in the left-right direction with respect to the main body cover 21 by the connecting piece 35. FIG. 8A shows a state in which the connecting piece 35 is not extended, and FIG. 8B shows a state in which the connecting piece 35 is extended in the lateral direction. 22 and 23 can be adjusted so as to freely project in the left-right direction with respect to the main body cover 21.

Next, a description will be given of a mounting structure of the hook 40 paired with the hook 36. As shown in FIGS. 10 and 11, a hook 40 is attached to a strip-shaped mounting piece 51 made of the same material as the outer sheet 30 on the left and right sides of the end of the outer sheet 30 of the main body cover 21. is there. The attachment pieces 51 are sewn to the outer sheet 30 at both sides and substantially at the center indicated by a, b, and c in the figure so that gaps 52 are formed between the attachment pieces 51 and the outer sheet 30. . That is, since the attachment piece 51 and the outer sheet 30 are each flexible, a gap 52 can be easily formed between the attachment piece 51 and the outer sheet 30. To make the hooks 36, 40 fit easily.

Next, the configuration of the side covers 22 and 23 will be described. Since the side covers 22, 23 are symmetrical, only one side cover 22 will be described, but the other side cover 23 has the same configuration. As shown in FIG. 5, the side cover 22 is formed in a substantially bag shape by an outer sheet 43 and an inner sheet 44, and the inside is filled with a heat insulating material 45. In FIG. 1, the inner sheet 44 of the side cover 22 is indicated by oblique lines. The outer sheet 43 and the heat insulating material 45 of the side cover 22 are made of the same material as that of the main body cover 21, and the inner sheet 44 is made of, for example, flexible and flame-retardant Marinetex.

The peripheral portion of the outer sheet 43 is folded back on the upper surface of the peripheral portion of the inner sheet 44, and the portion is sewn with a sewing machine or the like. In this case, after filling the inside of the side cover 22 with the heat insulating material 45, the last side is sewn. The thickness of the heat insulating material 45 filled in the side cover 22 is smaller than the thickness of the heat insulating material 32 in a state where the main body cover 21 is filled. It should be noted that there is no particular problem with respect to the heat retaining effect even if the thickness of the heat insulating material 45 is made thinner than that of the main body cover 21, and the side covers 22 and 23 are folded inside the main body cover 21 via the connecting piece 35. This is because the valve may be attached to the valve.

FIG. 4 is a plan view of the side cover 22. A base of a belt 46 is sewn to one end of the outer sheet 43, and a buckle 48 is provided at the other end of the outer sheet 43. The base of the buckle piece 47 is sewn. The belt 46 and the buckle piece 47 are made of the same material as that of the main body cover 21, and a single member is folded back.

A hook 41 is attached to one end of the side cover 22, and a hook 42 paired with the hook 41 is attached to the other end. Then, the hooks 41 and 42 are fitted, and the belt 46, that is, the side cover 22 is fastened by inserting the distal end of the belt 46 attached to the distal end side of the side cover 22 into the buckle 48. be able to.

Next, the configuration of the neck covers 24 and 25 will be described. As shown in FIG. 9, an outer sheet 60 and an inner sheet 61 are formed in a bag shape, and the inside thereof is filled with a heat insulating material 62. ing. The outer sheet 60, the inner sheet 61, and the heat insulator 62 of the neck covers 24, 25 are made of the same material as that of the side covers 22, 23. As in the case of the side covers 22 and 23, the neck covers 24 and 25 are formed such that the peripheral edge of the outer sheet 60 is folded over the peripheral edge of the inner sheet 61 and sewn at these portions.

As shown in FIG. 1, the neck covers 24 and 25 are formed in a substantially rectangular shape, and the base of a belt 63 formed of the same material as the outer sheet 60 is provided on the inner surface of one of the neck covers 24. Are sewn, and the base of a buckle piece 65 having a buckle 64 fastened to the belt 63 attached to the end thereof is similarly sewn. The belt 63 and the buckle pieces 65 are made of the same material as the outer sheet 60, and are formed in the same manner as the belt 46 and the buckle pieces 47.

By the way, according to the shape and the size of the valve 10, the body cover 21, the side covers 22, 23, and the neck covers 24, 25 of each member constituting the heat insulating cover 20 are formed in a plurality of sizes in advance. Each member is combined and sewn in accordance with an order from a user to form a heat insulating cover 20 as a finished product. The main body cover 21, the side covers 22, 23, and the neck covers 24, 25 are formed in advance so as to have different vertical dimensions and horizontal dimensions, respectively.

Here, in the related art, a heat insulating cover having a size just fitting to the valve 10 is formed by accurately cutting the size of the valve 10. However, in the present invention, the heat insulating cover is connected to the main body cover 21. The pieces 35 allow the side covers 22, 23 to protrude laterally by the width of the connecting piece 35, and the neck covers 24, 25 also protrude vertically from the body cover 21 by the connecting piece 34. Therefore, even if the size and shape of the valve 10 are slightly different from each other by the dimension amount that allows the protrusion, the valve 10 can be sufficiently covered.

When the sizes of the main body cover 21, the side covers 22, 23 and the neck covers 24, 25 are determined, the side covers 22, 23 and the neck covers 24, 25 are sewn to the main body cover 21, and the heat insulating cover 20 is formed. Will be formed. The outer edge of the connection piece 34 of the body cover 21 and the edge of the outer surface sheet 60 of the neck covers 24 and 25 are stitched along the sides, and the neck covers 24 and 25 are attached to the body cover 21 respectively. . Here, the neck covers 24 and 25 are protruded from the main body cover 21 by the flat and flexible connecting pieces 34 on the main body cover 21 side.

As shown in FIG. 1, one end of the connecting piece 35 is formed integrally with the inner sheet 31 of the main body cover 21, and the other end is connected to the side covers 22, 23. Then, the side covers 22 and 23 are attached to the main body cover 21. Here, as shown in FIG. 7, the connecting piece 35 made of the same material as the outer sheet 30 has flexibility, so that the connecting piece 35 shown in FIG. By extending in such a flat shape, the side covers 22 and 23 can freely project to both sides with respect to the main body cover 21.

FIGS. 13 to 15 show a state in which the heat insulating cover 20 formed as described above is mounted around the valve 10. Apply the heat retaining cover 20 spread from below the lower part 10 and wind the valve 10 around it. Then, the hooks 36 and 40 of the main body cover 21 are respectively stopped, and furthermore, both side portions of the side covers 22 and 23 cover the ends of the peripheral surface of the heat retaining cover 15 so that the side covers 22 are closed. , 23 are moved laterally to determine the position. Then, the hooks 41 and 42 are fitted, and the belts 47 of the side covers 22 and 23 are fastened to fix the ends of the side covers 22 and 23 to the cover 15 (the pipes 1 and 2 side). Further, since the end portions of the side covers 22 and 23 are fastened by the belt 47, the inner surfaces of the side covers 22 and 23 can be reliably brought into contact with the outer surface of the cover 15, so that the area around the valve 10 can be reduced. Heat dissipation can be reliably prevented.

As shown in FIG. 13, when the heat insulating cover 20 is mounted on the valve 10 side, the diameter from the middle of both sides of the main body cover 21 is adjusted so as to fit in the size from the flanges 11 and 12 to the cover 15. Is gradually reduced, and the whole is inclined. As a result, as shown in FIG. 13, the heat retaining cover 20 can be attached neatly even around the valve 10 having irregularities, and can be stored beautifully.

The neck covers 24, 25 are positioned by moving the two neck covers 24, 25 located in a substantially cylindrical shape around the handle shaft 14 of the valve 10 up and down by the connecting piece 34. Then, the belt 63 is stopped so as to completely cover the upper part of the valve 10, so that the neck covers 24 and 25 are attached to the upper part of the valve 10. As described above, the heat retaining cover 20 of the present invention can be easily and quickly attached to the valve 10 by the hook and the belt. Of course, it is possible to easily remove the heat retaining cover 20. In addition, since the belt is stopped, the heat retaining cover 20 can be brought into close contact with the pipes 1 and 2 and the handle shaft 14 side, so that the heat retaining property can be further improved.

FIG. 13 is a side view showing a state where the heat insulating cover 20 is mounted, FIG. 14 is a cross-sectional view, and FIG. 15 is a partially broken plan view. As shown in FIG. 14, since the valve 10 itself, the pipes 1 and 2 and the end of the cover 15 are completely covered, it is possible to prevent heat radiation from the valve 10 and its surroundings, thereby exhibiting an energy saving effect. I can do it. In particular, the distance between the end of the cover 15 and the valve 10 is not always constant due to its construction. However, since the side covers 22 and 23 can be expanded and contracted in the horizontal direction by the connecting piece 35, the pipes 1 and 2 are It can be covered without exposing it. Further, since the ends of the main body cover 21 and the side covers 22, 23 are overlapped and covered on the upper surface of the mating part of the main body cover 21 and the side covers 22, 23, heat radiation from the mating part is also prevented. can do.

Further, in order to fit the heat insulating cover 20 around the valve 10, the side covers 22, 23 and the neck covers 24, 25 are respectively moved with respect to the main body cover 21 to mount the heat insulating cover 20. It is as if the heat insulating cover 20 is cut and formed in accordance with the dimensions of the valve 10, so that the heat insulating cover 20 fits around the valve 10 well, improves the appearance, and exhibits a design effect. It is a thing.

In the embodiment described above, the side covers 22 and 23 and the neck covers 24 and 25 are configured so as to be able to expand and contract with respect to the main body cover 21. In the covers 24 and 25, the connection pieces 34 are used, but the present invention is not limited to this. For example, at the place where the main body cover 21 is attached to the side covers 22, 23, and the neck covers 24, 25, a planar fastener having dimensions in the protruding direction is attached, and the side covers 22, 23, or the neck cover 24 are attached. , 25 may be removably attached to any protruding position with a planar fastener. In this case, it goes without saying that a heat-resistant material is used for the sheet fastener.

By the way, as shown in FIG. 14, the position of the valve 10 is not always interposed between the straight pipes 1 and 2, and the pipe is connected to only one of the valves 10. The other may be connected to a bent pipe. Further, the valve 10 may be directly attached to the opening on the device side, or the other of the valve 10 directly attached to the device side may be attached to a bent pipe. In such a case, as shown in FIG. 13, when the side covers 22 and 23 are protruded in the lateral direction and attached to the valve 10, the side covers 22 and 23 become an obstacle. Therefore, as shown in FIG. 12, the side covers 22 and 23 are folded inside the main body cover 21 so that the valve 10 is covered with the main body cover 21 alone.
