Description

  The present invention relates to a heat shield cover, and more particularly, to a heat shield cover for safely covering a combustion gas pipe of a gas turbine reaching 600 degrees to 1200 degrees, an exhaust manifold of an internal combustion engine, and the like.

  As described above, the combustion gas pipes of gas turbines and exhaust manifolds of internal combustion engines that become hot as described above may cause a fire or adversely affect the human body and surrounding equipment. A thermal cover is coated.

  As the heat insulating cover, a large number of hooks are formed by punching a metal plate, a thin auxiliary heat insulating material having heat resistance and water resistance is fixed on the hook forming side, and a heat insulating material is fixed thereon. The entire surface of a thermal insulation material such as ceramic fiber or the like is wrapped with a surface material such as an aluminum foil, a stainless steel sheet, or a heat-resistant cloth, and the surface material is covered with a metal net. There are known ones equipped with a fixing wire for fixing the heat shield cover to an exhaust pipe or the like (utility model registration No. 3018095).

  The heat shield cover is fixedly attached to the combustion gas pipe, the exhaust manifold or the like in a close contact state. As a fixing means, a method using the wire 11 or the like (see FIG. 4), or a polymerization portion is a rivet. 12 is used (see FIG. 5). 4 and 5 show the case of a straight pipe, it goes without saying that it may be a curved pipe.

  However, in the case of a method using a wire or the like, it takes time to work, especially when concealing the joint on the back side of the pipe in order to emphasize the appearance, it is very difficult to work because of the work on the back side. It will be a waste. Further, since riveting is performed by inserting the tip of the riveter into the inside and outside of the joint, this method can be adopted when the combustion gas pipe to be mounted is a flanged pipe as shown in FIG. Can not.

  As described above, in the case of the conventional heat shield cover, there is a problem that the work for fixing to the combustion gas pipe or the like is troublesome or difficult to work, and the fixing means is limited by the pipe type. There is a problem.

  The present invention has been made to solve the above-described problems in the conventional heat shield cover, and it is an object to provide a heat shield cover that can be easily and quickly mounted and fixed regardless of the type of tube. To do.

  In order to solve the above-mentioned problems, the invention according to claim 1 is to maintain a linear shape with a circular arc cross section and a cover body in which the entire heat insulating material is covered with a heat resistant surface material such as an aluminum foil, a stainless steel thin plate, and a heat resistant cloth. Then, a heat shield cover composed of a steel-wound spring plate capable of reversibly deforming and deforming into a shoreline shape by eliminating the arc shape of the cross section is proposed. The wound spring plate may have locking means for locking each other at the end.

  In order to solve the above-mentioned problems, the invention according to claim 3 is directed to a cover body in which the entire heat insulating material is covered with a heat-resistant surface material such as an aluminum foil, a stainless steel plate, and a heat-resistant cloth, and the surface and / or the back surface of the cover body. Proposes a heat shield cover consisting of a steel spring plate with reversibly deformable steel that retains a straight line shape with a circular arc cross section that is fixed to the outer surface of the wire and deforms into a collinear shape by eliminating the circular arc shape. To do.

  In order to solve the above-mentioned problem, the invention according to claim 4 is directed to a cover body in which the entire heat insulating material is covered with a heat-resistant surface material such as an aluminum foil, a stainless steel plate, and a heat-resistant cloth, and one side and both sides of the cover body. From a reversibly deformable steel-wrapped spring plate that is housed in a bag formed on a side or an intermediate portion, retains a linear shape with a circular arc shape, and deforms into a saddle shape by eliminating the circular arc shape. Proposed heat shield cover.

  The heat shield cover according to the present invention includes a cover body having heat insulation and a wound spring plate for fixing the cover body to a combustion gas pipe or the like, so that the cover body and the wound spring plate are separated. If the cover body is covered with a combustion gas pipe or the like and then the wound spring plate is struck against the cover body, or if the cover body and the wound spring plate are integrated, the cover body is attached to the combustion gas pipe. The cover body can be securely and easily attached and easily removed by the action of the wound spring plate, respectively, by hitting it against the mounting part such as.

  The heat insulating cover according to the present invention has a cover body 1 in which the entire heat insulating material 2 is covered with a heat-resistant surface material 3 such as an aluminum foil, a stainless steel plate, a heat-resistant cloth, etc., and maintains a linear shape in a circular arc shape. It consists of a steel-wound spring plate 4 with reversible deformation that deforms into a shoreline shape by eliminating the arc shape.

  The cover main body 1 is as described above, and is basically the same as the conventional one. If necessary, the cover main body 1 is processed into a bellows shape as shown in FIG.

  The cover body 1 and the wound spring plate 4 may be separate or integrated. The example shown in FIG. 1 is the former, and the examples shown in FIGS. 2 and 3 are the latter.

  In the case of a separate body, a locking means for locking each other may be provided at the end of the wound spring plate 4. In the example shown in phantom lines in FIG. 1, a locking hole 6 is formed at one end of the wound spring plate 4, and a locking projection 7 that engages with the locking hole 6 is provided at the other end. After winding the wound spring plate 4, the locking projection 7 is fitted into the locking hole 6. Thus, it is possible to prevent the wound spring plate 4 from being loosened. Note that the locking hole 6 does not have to be a long hole as shown.

  When the length of the cover main body 1 is short, the number of the wound spring plates 4 may be one, but when the length of the cover main body 1 is long, a plurality of the spring plates 4 are used (two in the example of FIG. 1). The wound spring plate 4 may be fixed with an aluminum foil similar to that of the cover body 1, covered with a heat-resistant material, or colored so as not to stand out.

  In use, a desired portion is first wrapped with the cover body 1, and a wound spring plate 4 in a linear state is struck from above. Then, the wound spring plate 4 is immediately deformed into a winding shape, the cover body 1 is tightened, and the cover body 1 is fixed thereto. This fixing work is simple and can be easily and quickly performed regardless of whether the pipe to be loaded is a straight pipe or a curved pipe, even if it is in a confined space. .

  In the example shown in FIGS. 2 and 3, the cover body 1 and the wound spring plate 4 are integrated, and the wound spring plate 4 is inserted and arranged in the cover body 1. In other words, the bag portion 5 is formed on both sides of the cover main body 1 (there may be only one side or the intermediate portion), and the wound spring plate 4 can be inserted therein.

  In this case, as long as the heat insulating material 2 side of the cover main body 1 is struck against the mounting portion of the pipe, the cover main body 1 is curled up by the action of the wound spring plate 4 to wrap the pipe. .

  A configuration in which the wound spring plate 4 is fixed to the front surface of the cover body 1 and / or the outer surface of the back surface without forming the bag portion 5 is also conceivable. The method of use in this case is the same as in the example shown in FIGS.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
