The top view which shows the surface of the state before attaching the heat insulating cover for piping which concerns on this invention to piping. The top view which shows the back surface of the state before attaching the heat insulating cover for piping which concerns on this invention to piping. The perspective view which shows the shape when attaching the heat insulating cover for piping which concerns on this invention to piping. The partially expanded perspective view which shows the state which mounted | wore piping with the heat insulating cover for piping which concerns on this invention.

  Next, an embodiment of the present invention will be described based on the drawings. FIG.1 and FIG.2 is a top view which shows the surface of the state before mounting | wearing piping with the heat retention cover 10 for piping which concerns on this invention. Moreover, FIG. 3 is a top view which shows the back surface of the state before mounting | wearing piping with the heat insulating cover for piping which concerns on this invention. In FIG. 2, the reinforcing portion 3 is bent to the surface side so that a slide fastener provided on one side can be seen. The piping heat insulating cover according to the present invention will be described with reference to these drawings.

  As shown in FIGS. 1 and 2, the piping heat insulating cover 10 of the present invention includes a heat insulating portion 1 in which a heat insulating material is included in a cover body 10 a, and a first portion provided in the vicinity of both ends in the short direction of the heat insulating portion 1. Attached to the attachment / detachment portions 2a and 2b, a rectangular reinforcement portion 3 provided with a reinforcing member that covers the entire first attachment / detachment portions 2a and 2b from the back side when the pipes are attached, and provided in the vicinity of both longitudinal ends of the heat retaining portion 1 It has 2nd attachment / detachment part 4a, 4b.

  The piping heat insulating cover 10 of the present invention has the above-described configuration, and the outer periphery of the pipe is covered by the first attaching / detaching portions 2a, 2b, and the pipe insulating heat cover 10 is covered by the second attaching / detaching portions 4a, 4b. Since the outer peripheral surface of the pipe in the vicinity of both ends in the longitudinal direction is covered, heat radiation from the pipe can be reliably prevented. As an example of the material of the cover main body 10a, a silicon cloth can be used. However, various materials can be adopted as long as the heat resistant fiber cloth has a metal layer on the front surface and the back surface.

  Moreover, since the contact with the 1st attachment / detachment part 2a, 2b and the outer peripheral surface of piping is interrupted | blocked by the reinforcement part 3, the heat radiation from 1st attachment / detachment part 2a, 2b can be prevented. An example of the material of the reinforcing portion 3 is a silicon cloth, but various materials can be adopted as long as the material is a heat-resistant fiber cloth having a metal layer on the front surface and the back surface.

  The first attaching / detaching portions 2a and 2b are constituted by slide fasteners that are provided along the longitudinal direction of the pipe when the pipe is mounted. Thereby, the attachment or detachment operation | work with respect to piping can be performed easily.

  The heat insulating material included in the heat insulating portion 1 is preferably glass wool. Thereby, the effect of heat insulation and heat retention can be improved. In addition, instead of glass wool, a fiber heat insulating material such as rock wool may be used. Moreover, it is good also as a structure which makes the reinforcement part 3 enclose the heat insulating material similar to the heat insulating part 1. FIG.

  The heat retaining section 1 has a plurality of sections 5a, 5b, 5c, and 5d formed in parallel to the longitudinal direction by sewing the front and back surfaces of the cover body 10a with the thread 9. Thereby, it can prevent that the heat insulating material included in the heat retaining part 1 is biased, and the pipe can be uniformly warmed.

  The second attaching / detaching portions 4a and 4b are formed by inserting the string 6 into the insertion holes 7a and 7b provided in the vicinity of both ends in the longitudinal direction of the heat retaining unit 1, and by pulling and tying both ends of the string 6 When installing the pipe, the vicinity of both end portions in the longitudinal direction of the heat retaining section 1 is in close contact with the pipe.

  Thereby, the heat insulating material of the heat insulating part 1 is not exposed to the outside, and heat radiation from both ends in the longitudinal direction of the pipe heat insulating cover 10 can be prevented.

  FIG. 4 is a perspective view showing a shape of the piping heat insulating cover according to the present invention when attached to the pipe, and FIG. 5 is a partially enlarged perspective view showing a state where the piping heat insulating cover according to the present invention is attached to the pipe. FIG. In FIG. 4, the piping is not shown. The attachment and detachment with respect to the piping of the heat insulating cover for piping according to the present invention will be described using these drawings.

  When the piping heat insulating cover 10 is attached to the pipe, the first attaching / detaching portions 2a and 2b formed of slide fasteners are arranged so that the surface of the pipe heat insulating cover 10 shown in FIG. 1 contacts the outer peripheral surface of the pipe. Are joined to form a cylinder as shown in FIG.

  Then, as shown in FIG. 5, by pulling and tying both ends of the string 6a (6b) of the second attaching / detaching portions 4a and 4b, the vicinity of both end portions in the longitudinal direction of the heat retaining portion 1 is in close contact with the piping 8 when the piping is mounted. It becomes a state.

  Therefore, the heat insulating material of the heat insulating unit 1 is not exposed to the outside, and heat radiation from both longitudinal ends of the pipe heat insulating cover 10 can be prevented.

  Further, in the state where the heat insulating cover 10 for piping is attached to the pipe, the rectangular reinforcing portion 3 is located inside the slide fastener, and the reinforcing portion 3 comes into contact with the outer peripheral surface of the pipe. There is no contact between the outer peripheral surface and the metal surface of the slide fastener.

  Therefore, heat radiation from the first attaching / detaching portions 2 a and 2 b can be prevented by the reinforcing portion 3. Moreover, the installation and removal with respect to the piping 8 of the heat insulation cover 10 for piping can be easily performed by the slide fastener of the 1st attachment / detachment part 2a, 2b and the string 6a (6b) of the 2nd attachment / detachment part 4a, 4b.

  The heat insulation cover for piping according to the present invention is used for heat insulation and heat insulation by wrapping around the outer periphery of a pipe through which a fluid such as steam or hot water flows.
