Description

Heat-insulating pipeline

Technical Field

The utility model relates to the technical field of pipelines, concretely relates to heat preservation pipeline.

Background

The heat preservation pipeline is one of the widely used tubular product in the industry, is often used for the heat preservation cold insulation work of trades such as the transport of central heating, cooling and hot oil and warm room, freezer, chemical industry, and heat preservation pipeline is provided with the heat preservation at the pipeline skin usually, and outside heat source direct action is on the heat preservation, and uses for a long time like this to make this heat preservation performance reduce to lead to the heat preservation effect not good, and current heat preservation pipeline be monolithic structure, is not convenient for to the change of heat preservation, leads to the replacement cost higher.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a thermal insulation pipeline to hope to overcome the background art in the problem.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a heat preservation pipeline, includes pipeline main body, pipeline main body includes from interior pipe layer, heat preservation, aluminium foil reflection stratum, explosion-proof layer, rubber and plastic layer and the anticorrosive skin that sets gradually outward, connect through self-tapping screw between heat preservation, aluminium foil reflection stratum, explosion-proof layer, rubber and plastic layer and the anticorrosive skin, interior pipe layer is provided with the bulge along length direction, and interior pipe layer is integral structure with the bulge, and the bulge upper surface is the arc surface and is provided with the screw that is used for connecting the self-tapping screw at the bulge upper surface, the upper surface and the aluminium foil reflection stratum inner wall laminating of bulge.

Furthermore, the heat preservation layer is made of polyurethane, a notch for the protrusion to penetrate through is formed in the heat preservation layer in the linear direction of the heat preservation layer, and the thickness of the heat preservation layer accounts for 40% -50% of the total thickness of the pipeline main body.

Further, the inner wall of the inner pipe layer is coated with aluminum silicate.

Furthermore, the explosion-proof layer is a galvanized wire netting, and the explosion-proof layer is connected with the inner wall of the rubber and plastic layer to form a whole.

Further, the anticorrosive outer layer is a polyethylene pipe.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses be provided with the aluminium foil reflection stratum in the outside of heat preservation, explosion-proof layer and rubber and plastic layer, through setting up the rubber and plastic layer in order to block partial heat, reach the buffering and weaken thermal effect, thereby avoid a large amount of heat direct action on the heat preservation, be unfavorable for the long-term use of heat preservation, through setting up the intensity of explosion-proof layer in order to increase the pipeline, set up the bulge in the inner tube layer outside and connect each layer through self tapping screw, make and dismantle between each layer, thereby be convenient for change and reduce the replacement cost.
