Description

The utility model refers to reusable thermal insulation clothing that is used for thermal insulation of industrial fittings in heating networks, facilities and apparatus in the energy, chemical and oil refining industries.

BACKGROUND OF THE INVENTION

Known thermal insulation clothing for thermal insulation of facilities and pipelines, which consists of at least one thermal insulation body made up of a thermal insulation layer, which on one side is provided with a retaining element, which is a webbing. In the process of mounting thermal insulation clothing, the thermal insulation bodies are connected in place to one another by a heat-resistant metal thread. Prior to this, each insulation body is cut to the required size and shape and wrapped around the insulated object so that its insulation layer adjoins the outer surface of the insulated object portion and the retaining element contacts the environment. The thermal insulated garment wrapped around the heat-insulated object is retained in working position by connecting its longitudinal edges to each other by using a heat-resistant metal thread (1).

Also known is thermal insulation clothing for carrying out thermal insulation of facilities and pipelines, which differs from the one described above in that its retaining element is a heat-resistant metal foil / 2 /.

Known thermal insulation garments have low cost-effectiveness, which is that they are disposable only, because any dismantling of thermal insulation garments from the insulated object leads to its destruction, and their installation process is complicated and time-consuming and requires use special working tools and special work clothing for the staff. The complexity and labor-intensive capacity of construction of thermal insulation clothing is due to the fact that the size of the produced thermal insulation bodies constituting the complex thermal insulation clothing is limited and during its construction it is necessary to connect in place the individual parts with a heat-resistant metal thread. Personnel carrying out the thermal insulation operation of the site must be provided with special working clothing to protect it as much as possible from the accumulation of particles from the submerged thermal insulation layer (wad) in unprotected parts of the human body. Also, known thermal insulation garments have an aesthetic appearance.

The technical nature of the utility model

The task of the utility model is to create good-looking thermal insulation clothing that is highly cost-effective, resulting in easy and quick repeated installation and dismantling of the thermal insulation site without the use of special working tools and work clothing for service personnel.

This task is accomplished with a reusable thermal insulation garment comprising at least one insulation body made up of a thermal insulation layer provided with a retaining element. The retaining element comprises a thermal insulation layer along its entire length and consists of sewed to one another with a heat-resistant thread outer and inner parts made of heat-insulating fabric. The outer part of the retaining element is provided with at least one connecting element.

In one embodiment, the bonding element of the reusable thermal insulation garment consists of two parts. Its first part consists of a belt terminating with a buckle, which is fixed by a seam of heat-resistant thread to one end of the outer part and parallel to the two transverse ends of the retaining element. The second part of the connecting element consists of a second belt, provided at both ends with adhesive tapes, fixed by a seam of heat-resistant thread to the other end of the outer part and at the same parallel to the two transverse ends of the retaining element and at the same distance from them as the first. belt.

In this case, to the two ends of the reusable garment, along its width, and parallel to the first and second belts of the connecting element, the respective fastening elements, terminating with grooves in which the respective heat-resistant cords are threaded, are sewn with a thread-resistant thread.

When the shape of the thermal insulation object is complex and / or the size is very large, the number of thermal insulation bodies is more than one and they are connected to each other either by sewing along their connecting lines or by connecting elements. The shape and dimensions of thermal insulation bodies are determined by the shape and dimensions of the thermal insulation object.

In the case of the use of multiple thermal insulation bodies forming a composite thermal insulation reusable garment, it is preferable that the connecting element consists of a heat-resistant connecting thread, threaded in succession through a plurality of supports, fixed near the edges of the outer part of the retaining element. rivets.

The advantage of reusable thermal insulation clothing according to the utility model is its increased cost-effectiveness, which is reflected in its reusable use, due to the fact that the retaining element is made of flexible textile fabric, which rarely receives damage during disassembly and subsequent installation of thermal insulation. reusable clothing during repair / prophylaxis of the insulated object, and its construction allows for easy and quick re-assembly and dismantling without deterioration of parameters. thermal insulation clothing reusable without using special tools for its construction be designed and constructed in advance and for each type and frame size insulated object. The connection of its ends fixed to each other to form a reusable thermal insulation garment and fixing the formed reusable thermal insulation garment to the insulated object is accomplished only with the connecting and fastening elements present on the outside of the retaining element, which do not require special working tools and special working clothing for the staff, because the submerged thermal insulation layer is completely covered by the fabric of the retaining layer, which is why The particles remain inside the retaining element and are not in contact with exposed parts of the personnel body.

Another advantage of a reusable thermal insulation garment according to the utility model is its good appearance due to the retaining element being made of flexible heat-resistant fabric.
