Abstract

The utility model relates to building materials, particularly the improvement of an air conditioning pipe used for transferring hot and cold media. The utility model is characterized in that the outer wall of a base tube connected with a flange is sheathed with a heat-insulating layer and an outer tube in sequence. The base tube is fixedly connected with the outer tube through a rivet penetrating the heat-insulating layer. The processes are die moulding. The outer tube can be brushed with an antifouling paint layer for the goodly appearance and rust prevention of the tube wall. The utility model has the functions of fire prevention, water prevention, heat preservation, and sound insulation. Because of the adoption of casting from a single cut in the manufacturing manner, the utility model has low manufacturing cost, novel structure, practicality, and beauty.

Description

Once-through multi-functional air conditioner pipe

The utility model relates to structural material, specifically a kind of improvement of carrying cold and hot medium with the air-conditioning pipe.

Along with the generally raising of people's life, the building class is more and more higher, adopts building central centralized, half centralized air-conditioning cold and heat supply more and more, and this carries with regard to the pipeline that needs a large amount of cold and heat supplies.At present, the gas pipeline of this cold and heat supply often adopts steel plate to make or Glass Steel Tube, and pipe is outer to be incubated, and twines with thermal insulating material, and it is outer to do protection with galvanized sheet iron or aluminium platinum or other materials again.Its complex structure, construction sequence is loaded down with trivial details, and the cycle is long, the cost height, these materials are perishable, and working life is short.

The purpose of this utility model is the shortcoming at above-mentioned existence, provides a kind of simple in structure, is easy to construction, the air-conditioning pipe of long service life.

Technological points of the present utility model is: parent tube (5) outer wall that links to each other with flange (1) contains thermal insulation layer (3) and outer tube (2) successively, and parent tube (5) is through rivet (4) break-through thermal insulation layer (3) and outer tube (2) Joint.These processes are that one-off pattern is molded.Attractive in appearance and antirust for outer tube wall, its outer tube (2) can be brushed antiseptic oil enamelled coating (6).

The utility model has the advantages that: have the function of carrying cold and hot medium, because the riveted structure of inner and outer pipes, thin and the intensity of tube wall, rigidity are splendid, labor and material saving, structure is whole gathers, and it is little to take up space, do not need to stay construction operation space more, can reduce building cost, the job site is clean and tidy, also has the function of fire-proof and water-proof, heat preservation and soundproof.On manufacture method, adopt the casting once-through, thereby cost is lower, novel structure, both artistic and practical.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A view of Fig. 1.

The utility model parent tube (5) is to adopt fire-retardant inorganic chemical industry composite material to make, also available modified magnesite material, these materials are to inject mould by several powders and several auxiliary material mixing puddle form slurry, the moulding of molding chemical combination, this material is fire-resistant water-fast, the intensity height, plasticity is good, is easy to molding, can produce the pipeline of different shape size, utilize the insulation cold insulation sheet material and the coiled material of current function admirable again, when making airduct, it is once imported do in pipe framed, do one deck shell in appearance again, and suitable position makes it the common integral body (seeing accompanying drawing) that forms of inner and outer pipes and thermal insulation layer with interior tube and tube shell rivething.

Two ends of the present utility model adpting flanges (1), outer tube (2) shields to thermal insulation layer (3), simultaneously with interior pipe riveted joint, has strengthened the intensity of interior pipe, but tube thickness in the attenuate, thus material saved.Insulation cold insulation layer (square tubular sheet material, pipe coiled material) is generally with polystyrene foamed boards or rock cotton board; The size of the rivet of used cast molding (4) and rare close be definite as calculated according to caliber size and insulation layer thickness; Parent tube is to be responsible for, the pressure-bearing fed sheet of a media, and thickness determines according to caliber size and pressure-bearing.

Claims

1. once-through multi-functional air conditioner pipe has substrate, it is characterized in that parent tube (5) outer wall that links to each other with flange (1) contains thermal insulation layer (3) and outer tube (2) successively, and parent tube (5) is through rivet (4) break-through thermal insulation layer (3) and outer tube (2) Joint.
