Description

Collet

Technical field

This application involves heat insulation and preservation device fields, in particular to a kind of collet.

Background technique

Existing collet has a single function the air inlet system and exhaust system of equipment and engine using common heat-barrier material Package processing, this kind of collet do not have or not all with Water-proof and oil-proof, the characteristic for preventing fluid from entering collet. Heat-insulated cover material enters if any water will be greatly reduced heat insulation, enter if any the instantaneous splash of oily flammable liquid, easily make every The carrier that hot material becomes burning can make collet have fire risk, glue is distributed with around usual collet in the case of a high temperature Pipe, cable etc. are flammable body, if collet catches fire, the flammable body for surrounding of easily igniting leads to that more massive fire occurs.

The interior contact layer material of existing collet is usually netted or fabric structure, has the disadvantages that the knot Structure easily makes the fiber of collet be perforated through interior contact layer hole and drifts in air or be attached to equipment surface to cause environment Pollution, or stimulation or lesion are caused to personnel's skin or respiratory tract；Easily enter hot-air, and then influences the thermal insulation of collet Energy；The internal layer of collet is contact arrangement surface, if equipment has vibration or equipment surface uneven, easily inner layer material is caused to mention Preceding wear damage is to cause collet whole service life to shorten.

In addition, the edge of existing collet carries out bound edge processing using fabric, wear-resisting property is poor, and bound edge is easy damage Bad, internal material, which is easy to expose, after bound edge damage influences heat-proof quality, and the sharp edges of internal material be easy to cause personal injury.

For the above problem in the prior art, currently no effective solution has been proposed.

Utility model content

It is good that the main purpose of the application is to provide a kind of heat insulation and preservation effect, and grease proofing equal sputter of fluid instantaneously pass through surface Insulating is penetrated into, the good collet of bound edge wear-resisting property is bad to solve existing collet grease-proof and waterproof effect, equipment spray The greasy dirt splashed penetrates into key technical problem easy to cause fire inside collet by gap between inside and outside layer surface latitude and longitude, and Environmental pollution caused by existing heat insulation layer fiber is exposed, heat-proof quality difference and easily generation abrasion influence service life, bound edge Wear-resisting property is poor, and heat-proof quality is influenced after damaged, causes the technical issues of personal injury.

To achieve the goals above, according to the one aspect of the application, a kind of collet is provided, the collet includes Sheet-metal layers, heat insulation layer and the tissue layer set gradually from inside to outside, the edge of the collet are provided with bound edge net, institute Bound edge net is stated using wire mesh.
