Abstract

A high-temperature pipeline heat insulating layer belongs to the technology of heat insulation sealing design, relating to the improvement of the existing high-temperature conduit heat insulation sealing technology. The high-temperature pipeline heat insulating layer comprises an air interlayer (2), a heat insulating layer (6), a heat insulating layer lining ring (3), gas leakage detecting preformed holes (4) and a wire mesh (5), wherein the heat insulating layer (6) is supported with the outer surface of a high-temperature pipeline through the heat insulating layer lining ring (3); the air interlayer (2) is arranged between the heat insulating layer (6) and the outer surface of the high-temperature pipeline; and the gas leakage detecting preformed holes (4) are distributed on the heat insulating layer (6) and covered with the wire mesh (5). The high-temperature pipeline heat insulating layer takes air as a heat insulating medium; the heat insulating layer is made of a composite material formed at a high temperature and combined with the heat insulating lining ring structure, so that the use strength requirements can be met at low thickness; compared with the traditional high-temperature pipeline heat insulating layer, the weight of the heat insulating layer is greatly reduced, and also the maintenance can be performed conveniently; the heat insulating layer of the composite material formed at a high temperature is good in gas tightness; and as the gas leakage detecting preformed holes are formed on the heat insulating layer, probes can be arranged on the holes, so that the leakage detection function is easy to be implemented.

Description

A kind of new type high temperature pipeline heat insulation layer
Technical field
The invention belongs to the heat-insulating and sealing designing technique, relate to improvement existing high temperature conduit heat-insulating and sealing technology.
Background technique
The coated employing internal layer of the high temperature conduit heat insulation layer of installing on the existing aircraft is certain thickness blanket of glass wool, and outer form of twining glass tape can satisfy the catheter surface temperature requirement, but have following three problems:
1) the blanket of glass wool specification is limited, and heat insulation layer weight is heavier;
2) conduit is in case the damaged leakage of generation owing to the uncertainty that hot gas flows, can't utilize fixing detection line to survey;
3) breakage easily in use takes place in the cotton felt of heat insulation layer inner layer glass, glass outer silk ribbon, and maintenance workload is big.
Summary of the invention
The objective of the invention is: a kind of new type high temperature conduit heat insulation layer is provided, solves the problem of thermal insulation of high temperature conduit and leak detection, but and weight reduction.
Technological scheme of the present invention is:
A kind of high temperature conduit heat insulation layer, it is characterized in that, comprise air buffer, heat insulation layer, preformed hole and wire gaze are surveyed in heat insulation layer lining ring, gas leakage, wherein, heat insulation layer and high temperature conduit outer surface support by the heat insulation layer lining ring, are air buffer between heat insulation layer and the high temperature conduit outer surface, gas leakage is surveyed preformed hole and is arranged on the heat insulation layer, and covers with wire gaze.
It is even, consistent that described air buffer moves towards thickness along high temperature conduit.
Described heat insulation layer material therefor is a kind of in epoxy resin, polyether-ether-ketone, three kinds of materials of polyimide
Beneficial effect of the present invention: the present invention is adiabatic medium with air, the heat insulation layer composite material of high-temperature molding, and be aided with heat insulation layer lining ring structure, can be implemented in and satisfy the working strength requirement under the less thickness, compare with conventional high-temperature pipeline heat insulation layer, alleviated the weight of heat insulation layer greatly, also maintained easily; The composite material thermal insulation layer tightness of high-temperature molding is good, opens gas leakage thereon and surveys preformed hole, just can arrange detecting head at this tapping, is easy to realize the leak detection function.

Embodiment
As shown in Figure 1, a kind of device that satisfies thermal insulation of high temperature conduit and leak detection function comprises metal catheter 1, air buffer 2, and heat insulation layer lining ring 3, preformed hole 4 is surveyed in gas leakage, wire gaze 5, heat insulation layer 6, heat insulation layer 6 material therefors are epoxy resin.With air is adiabatic medium, can adjust the thickness of air buffer 2 according to the conduit different surfaces temperature requirement in using, heat insulation layer lining ring 3 can guarantee that heat insulation layer 6 still can keep certain profile under less thickness, and the thickness of air buffer 2 is even, and the catheter surface temperature is even; The sealed at both ends metal catheter 1 that arrives of heat insulation layer 6 is reserved gas leakage and is surveyed preformed hole 4, and covers with wire gaze 5 on the heat insulation layer 6, the gas that tube leaks goes out can only be surveyed preformed hole 4 by gas leakage and reserve, and can conveniently realize surveying.
