Abstract
The utility model relates to a composite thermal insulation wind pipe and joint, which relates to a pipe and a pipe joint, particularly a ventilating pipe and the pipe joint which is used for a central air-condition. The utility model comprises a straight wind pipe, a bending pipe joint, and a three-way pipe joint. Openings of the straight wind pipe, the bending pipe joint, and the three-way pipe joint are provided with flange edges which are used for connection. The walls of the straight wind pipe, the bending pipe joint, and the three-way pipe joint are formed by the composite of metal inner layers, middle thermal insulation layers, and fire retardation inorganic glass fibre reinforced plastic outer layers. A paint layer which plays the role of protection and decoration can be coated on the outer surface of a fire retardation inorganic glass fibre reinforced plastic outer layer.
Description
The utility model relates to a kind of pipe and pipe joint, ventilation duct and pipe joint that particularly a kind of central air-conditioner is used.
Existing central air-conditioner has plenty of the sheet material of using field fabrication with ventilation duct and pipe joint, makes, installment work efficient is lower; What have does not have a heat insulation function, wastes energy; Have in order to be incubated at ventilation duct outer wrapping thermal insulation layer, both influenced outward appearance, increased the workload when installing again, the insufficient strength that has or be subject to external environment condition and corrode, sturdy and durable inadequately.
The purpose of this utility model is: the technological scheme of a kind of hvac duct and pipe joint is provided, makes this thermal insulation wind pipe and pipe joint be suitable for batch production production, have heat insulation function, simple installation is saved cost, and is sturdy and durable, and can fire-retardant fireproof.
The technical solution of the utility model is: hvac duct and pipe joint, comprise straight airduct, elbow, three-way union, and their opening end all is useful on the flange connecting limit, and screw is arranged on the flange edge.Their wall is composited for outer three layers by metal nexine, middle thermal insulation layer and fire-retardant FRIM.It is circle, square, rectangular straight tube, bend pipe, three-way pipe that the metal nexine adopts galvanized steel plain sheet, corrosion resistant plate, aluminium sheet or aluminium alloy plate to manufacture radially disconnected cross section.Middle thermal insulation layer adopts polyethylene foam, styrofoam, glass cotton to be clipped between metal nexine and the glass fibre reinforced plastics skin.Fire-retardant FRIM is outer to process with urea formaldehyde resin and fiberglass gridding or cloth.The outer field outer surface of glass fibre reinforced plastics has been coated with the coating or the enamelled coating of decoration, protective action.
Major advantage of the present utility model is: help batch production production, simple installation helps improving installment work efficient, and reduce cost of investment is installed, high insulating effect, favourable energy-conservation, and also sturdy and durable, fire-retardant fireproof, appearance better appearance.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1: the straight airduct sectional view of complex heat-preservation;
Fig. 2: complex heat-preservation elbow sectional view;
Fig. 3: complex heat-preservation three-way union sectional view.
Embodiment 1:
Hvac duct and pipe joint, comprise straight airduct (see figure 1), elbow (see figure 2) and three-way union (see figure 3), the two ends of straight airduct and elbow are useful on the flange edge 1 of connection respectively, screw 5 is arranged on the flange edge 1, three ends of three-way union also are useful on the flange edge 1 of installation respectively, screw 5 is also arranged on the flange edge, straight airduct, the wall of elbow or three-way union is by metal nexine 3, middle thermal insulation layer 2 and fire-retardant FRIM are composited for outer 4 three layers, earlier with sheet metal such as galvanized steel plain sheet, corrosion resistant plate, aluminium sheet or aluminium alloy plate are made into radially disconnected cross section for circular, oval, square, the metal nexine 3 of rectangular or other shapes, then with middle thermal insulation layer material such as polyethylene foam, the styrofoam or the glass bale of cotton are rolled in metal nexine 3 outsides, are processed into fire-retardant FRIM skin 1 at middle thermal insulation layer 2 external application urea formaldehyde resins and fiberglass gridding or glass cloth again.
Embodiment 2:
With embodiment 1 difference be: the coating or the enamelled coating that have been coated with decoration and protective action at the outer surface of fire-retardant FRIM skin 1.
Claims (5)
