Problems solved by technology

[0005] The installation of the gasket using the hook connection method on the heating equipment is cumbersome, and a large number of people are required to participate in the assembly, and the defect rate is high. Wrong, once there is an installation error, it will be troublesome to disassemble. The tail of the hook will stick to the gasket, which will easily cause the gasket to deform and cause the seal to fail.

Embodiment 1

[0032] Such as Picture 1-1 , 1-3 As shown, a paste-type high-temperature-resistant gasket, the paste-type high-temperature-resistant gasket 1 is in the shape of a long strip, which includes a tubular heat-insulating layer 1-1 made of an outer layer of high-temperature-resistant heat-insulating material and a mesh wire elastic lining of the inner layer. Skeleton 1-2, high temperature resistant heat insulation materials include glass fiber, basalt fiber and carbon fiber, etc., any axial outer side of the tubular heat insulation layer 1-1 is provided with high temperature resistant double-sided adhesive strip 2, high temperature resistant self-adhesive adhesive strip 2 can be Continuously or discontinuously arranged on the axially outer side of the tubular heat insulating layer 1-1, or according to actual needs, continuously or discontinuously and not in the same straight line and pasted on the outer circumference of the tubular heat insulating layer 1-1, and then pasted The hig...

Embodiment 2

[0035] Compared with the first embodiment above, the beam opening structure 5 of this embodiment has the following deformations:

[0036] Such as diagram 2-1 As shown, in this embodiment, the end of the adhesive high temperature resistant gasket 1 is turned inward, and the cut part of the adhesive high temperature resistant gasket 1 is turned inside the gasket cavity to prevent debris from falling at the fracture. It has the characteristics of simple operation and material saving.

Embodiment 3

[0038] Compared with the above-mentioned embodiments, the beam port structure 5 of this embodiment has the following deformations:

[0039] Such as Figure 2-2 As shown, this embodiment adopts the method of binding the end of the paste-type high-temperature resistant gasket 1 with a staple 5-2, which can also achieve the purpose of preventing debris from falling at the fracture. This structure has the advantages of simple operation, firm connection, safety and reliability. specialty.

Abstract

The invention discloses an adhesive type high-temperature-resistant gasket. The adhesive type high-temperature-resistant gasket is in a long strip shape and comprises a tubular heat insulation layer on an outer layer and a net-shaped metal wire elastic framework of a lining. A high-temperature-resistant double-sided adhesive tape is arranged on any outer side in an axial direction of the tubular heat insulation layer. The invention provides the adhesive high-temperature-resistant gasket which is convenient and fast to install, operation errors are reduced or even eradicated and sealing performance is improved.

Description

technical field [0001] The invention relates to an adhesive type high temperature resistant washer. Background technique [0002] At present, it is necessary to use heat-insulating gaskets around the doors of charcoal ovens and some heating equipment, and these gaskets mainly play a role of heat insulation, heat preservation and sealing. [0003] Usually the material of these gaskets is felt or packing, and mineral wool is also used as a thermal insulation material. These structures usually cannot guarantee to maintain the original performance after high temperature. The felt and packing will shrink after being heated, and mineral wool There will be an impact on the environment. [0004] With the wide use of new materials such as glass fiber and carbon fiber, a new direction has been brought to the upgrading of heat insulation gaskets for heating equipment. A tubular gasket appears on the market, and the tubular gasket is installed on the heating equipment door. The method...
