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 to 1200 degrees, a muffler of an internal combustion engine, and the like.

  As mentioned above, gas turbine combustion gas pipes and internal combustion engine mufflers, etc. that become hot may cause a fire or adversely affect the human body and surrounding equipment. The cover is covered.

  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 muffler or the like in a close contact state. As the fixing means, a method using the wire 11 or the like (see FIG. 3), or a method of fixing the overlapping portion with the rivet 12. (See FIG. 4). 3 and 4 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. 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.

  In addition, when used in equipment with large vibrations such as construction machines, there is a problem that if the heat-insulating cover is not tightly wound, it is displaced due to vibrations.

  As described above, in the case of the conventional heat shield cover, there is a problem that the fixing work to the combustion gas pipe or the like takes time or is difficult to work, and the fixing means is limited by the pipe type. There is a problem, and further, there is a problem that if it is not tightly wound, it will shift by vibration.

  The present invention has been made to solve the above-described problems of the conventional heat shield cover, and it is an object to provide a heat shield cover that can be fixed and fixed easily and quickly with good appearance regardless of the type of pipe. And

  In order to solve the above-mentioned problems, the invention according to claim 1 is provided with a cover body in which at least the outer surface side of the heat insulating material is covered with a heat-resistant surface material such as an aluminum foil, a thin stainless plate, and a heat-resistant cloth, and one end edge of the cover body 1 or a plurality of male hooks are attached, and a heat insulating cover is proposed in which a female hook corresponding to the male hook is attached to the other end edge of the cover body.

  In order to solve the above-mentioned problem, the invention according to claim 2 is provided with a cover body in which at least the outer surface side of the heat insulating material is covered with a heat-resistant surface material such as an aluminum foil, a stainless steel thin plate, a heat-resistant cloth, and the like. 1 or a plurality of male hooks are attached, a female hook corresponding to the male hook is attached to the other end edge of the cover body, and a heat insulating cover is proposed in which a heat resistant fiber layer is provided on the inner surface side of the cover body.

  In order to solve the above-mentioned problem, the invention according to claim 3 is provided with a cover body in which at least the outer surface side of the heat insulating material is covered with a heat-resistant surface material such as an aluminum foil, a stainless thin plate, a heat-resistant cloth, and the like. 1 or a plurality of male hooks are attached, a female hook corresponding to the male hook is attached to the other end edge of the cover body, and a heat insulating cover is proposed in which a glass fiber layer is provided on the inner surface side of the cover body.

  In the heat shield cover according to the present invention, a male / female hook is attached to the edge of the cover body having heat insulation, and the edge is connected with the male / female hook after being wrapped around a muffler, etc. It is easy, quick and stable in a tightened state, and it can be done with good appearance, it is easy to remove, and it has the effect of improving work efficiency and cost, and if it is equipped with a glass fiber layer, its air Due to the holding layer, the heat shielding property is improved, and the cushioning property has an effect that it is difficult to move even if it receives a large vibration.

  The best mode for carrying out the present invention will be described with reference to FIGS. Although the illustrated example is a straight pipe type, there is no particular change even if it is a curved pipe type.

  The heat shield cover according to the present invention is provided with a cover main body 1 in which at least the outer surface side of the heat insulating material 2 is covered with a heat-resistant surface material 3 such as an aluminum foil, a stainless steel thin plate, a heat-resistant cloth, etc. A plurality of male hooks 4 and female hooks 5 corresponding to the male hooks 4 are respectively attached to the other end edges.

  The cover body 1 is as described above, and is basically the same as the conventional one. If necessary, the cover body 1 is processed into a bellows shape as shown in the drawing so that the bending deformation is easy. . And preferably, the glass fiber layer 6 is provided on the inner surface.

  In use, the desired location is wrapped with the cover body 1, the female hook 5 installation side edge is held down by hand, the male hook 4 installation side is pulled strongly with the other hand, and the male hook 4 is pushed into the corresponding female hook 5. . At that time, in order to make the cover body 1 tightly adhere to the combustion gas pipe or the like, the mounting positions of the male hook 4 and the female hook 5 need to be adjusted in advance to the pipe diameter. Thus, a stable tightening state can always be obtained. When removing the heat shield cover, the male hook 4 installation side edge of the cover body 1 may be pulled strongly. Of course, the male hook 4 may be on the inside and the female hook 5 on the outside.

  For example, in the case where a large vibration occurs like a construction machine, if the cover body 1 has a low degree of adhesion, the cover body 1 is easily displaced. In such a case, it is effective to use a heat-resistant fiber layer, preferably a glass fiber layer 6 provided on the inner surface. Glass fiber is resistant to heat, and the cushioned glass fiber layer 6 completely fills the gap between the cover body 1 and the pipe peripheral surface, thereby preventing the heat shield cover from shifting. Moreover, since the glass fiber layer 6 becomes air layer holding | maintenance, the heat-shielding effect improves.

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

It is a perspective view which shows the use condition of one Embodiment of this invention. It is a partial detail drawing which shows other embodiment of this invention. It is a figure which shows the structural example of the conventional heat insulation cover. It is a figure which shows the other structural example of the conventional heat insulation cover.
