Abstract

The utility model discloses a complex warming tube including an interlayer transporting tube, a medium warming tube and an outer layer protective tube. The utility model has the advantages of good warming effect, easy positioning, time and effort saving, greatly saving work strength of workers, saving cost and improving the work environment; therefore, the production provides an admirable complex warming tube for people.

Description

Compound thermal insulating pipe

(1) technical field: the utility model relates to the cold and hot component of a system of building construction, particularly a kind of compound thermal insulating pipe.

(2) background technique: its interior pipe of insulation pipe of delivering hot water or cold air is the long bobbin of metallic type in the cold and hot supply system of building construction at present; in order to be incubated or to prevent heat radiation; the trial work workman will be at one one combination bag of metal tube outer wall one deck perlite block; do thermal insulation layer and protective layer at perlite block outer wall bag one deck asbestos, malthoid or aluminium skin again, form insulation pipe at last.Here it is traditional pipeline binding type thermal-insulation mode of movement.This insulation pipe one side thermal insulation layer combination slit is many, and heat insulation effect is poor, wraps up construction complexity such as perlite block and asbestos on the other hand from level to level at the metal tube outer wall, and labor intensity is big, and working life is short, and the also easy befouling environment of asbestos material.

(3) summary of the invention: the purpose of this utility model will provide a kind of with synthetic admittedly integral body of internal layer delivery pipe, middle level thermal insulation pipe and the outer protection tube and high insulating effect exactly, and construction is easy to compound thermal insulating pipe.The utility model be achieved in that it be by interior, in, outer three layers of pipe combine.Its internal layer is long tubular delivery pipe; bag is put a coaxial protective tube in the periphery of internal layer delivery pipe; and make between the inwall of the outer wall of internal layer delivery pipe and the outer protection tube and form a long tubular cavity; in long tubular cavity, fill full thermal-protective material polyurethane integral foam; thermal insulation pipe in the middle of forming; and, form compound thermal insulating pipe by the synthetic admittedly integral body of delivery pipe three pipes of polyurethane integral foam with the thermal insulation pipe and the internal layer in outer field protective tube, mesosphere.In use as long as connect this Guan Yijie one joint affixed logical.The utility model high insulating effect is installed easily, and laborsaving saving time greatly reduces workpeople's labor intensity, saved engineering cost and improved working environment, and its appearance provides a kind of desirable compound thermal insulating pipe for people.

(4) description of drawings;

Accompanying drawing 1 is the utility model structural representation.

In the accompanying drawing 11---the outer protection tube, 2---the middle level thermal insulation pipe, 3---the internal layer delivery pipe.

(5) most preferred embodiment: with reference to accompanying drawing 1: internal layer delivery pipe (3) is long tubular; it adopts the PP-R plastics to make; bag is put a coaxial the outer protection tube (1) in the periphery of internal layer delivery pipe (3); protective tube (1) it adopt the PVC plastics to make; between the inwall of the outer wall of internal layer delivery pipe (3) and the outer protection tube (1), form an oval tubular cavity; filling with insulation material polyurethane integral foam in cavity; thermal insulation pipe (2) in the middle of forming; by the polyurethane integral foam with outer field protective tube (1); the synthetic admittedly integral body of delivery pipe (3) three pipes of thermal insulation pipe in mesosphere (2) and internal layer forms compound thermal insulating pipe.
