Background

With the enhancement of energy-saving and environment-friendly awareness, how to well preserve and save the heat of pipelines for transporting heat energy or cold energy becomes an important subject faced by people. The reducing is an indispensable main accessory for pipeline energy transmission and also an important link for pipeline heat preservation. Traditional pipeline heat preservation inlayer mostly uses rock wool, and nonrust steel sheet or aluminum plate carry out the outsourcing again for the outer jacket, to the heat preservation of pipeline, need not only need corresponding processing machine equipment at the job site processing preparation, will have a large amount of processing personnel moreover, and whole construction is very time-consuming, and the cost of labor is too high, pollutes seriously. The disassembly is complex during maintenance, and the disassembled objects can not be used repeatedly, thereby causing loss and secondary pollution, causing waste and increasing the comprehensive cost of products. Along with the lack of the energy, energy-conservation more and more receives people's general attention, how to reduce the loss of heat energy or cold energy in pipeline transportation, improves pipeline heat preservation site constructor's work efficiency, prolongs pipeline insulation construction's life, improves pipeline insulation material reuse rate, and reduce cost becomes a technical problem that people need to solve urgently.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a metal outer protective layer reducing pipeline heat-insulating energy-saving shell which is simple in structure, good in heat-insulating effect, high in direct installation efficiency, detachable, reusable and capable of saving production cost, and a processing and manufacturing process of a construction site is omitted.

The purpose of the utility model is realized as follows: the utility model provides a metal outer jacket reducing pipeline heat preservation energy-saving shell, is including setting up the heat preservation on the reducing pipeline surface and setting up the outer jacket on the heat preservation, the heat preservation is two half tubular structure of reducing of cutting open, the heat preservation surface sets up the outer jacket, the outer jacket is the half tubular structure of reducing that matches with the heat preservation, the outer jacket includes catching groove and socket, and the socket lock is in the catching groove for the outer jacket parcel is on the heat preservation, its both ends of outer jacket use bore the tail nail fixed.

Preferably, the inner surface and the section of the heat-insulating layer are both provided with a layer of heat-insulating glue which is adhered to the outer surface of the reducing pipeline.

Preferably, the outer protective layer is made of 304 stainless steel or iron sheet or color steel or aluminum skin, and the thickness of the material is 0.3-0.5 mm.

Preferably, the insulating layer is made of rubber plastic or aluminum silicate, the thickness of the insulating layer is 30-100mm, and the heat conductivity coefficient is 0.025-0.03W/M.K.

As the preferred scheme, outer jacket both ends one end is provided with the protruding muscle in border, and the other end is provided with the protruding muscle of seam.

The utility model has the beneficial effects that: the metal outer protective layer reducing pipeline heat-insulating energy-saving shell can be manufactured into heat-insulating standard parts with the same specification and size by heat-insulating reducing, and the reducing of the standard part to be heat-insulating is wrapped in the reducing of the metal outer protective layer pipeline with the same specification and fixed only according to the specification and size of the reducing. The installation is simple, and the leakproofness is good, has left out the manufacturing process of job site, has improved the efficiency of construction, can used repeatedly, has avoided traditional heat preservation just condemned defect once demolishs. Wherein the outer jacket material is the metal material, can improve the effect of anti-wind blowing sun exposure rain by a wide margin, and it is effectual to keep warm, has prolonged life.
