Abstract
The utility model relates to a combined ventilation pipeline composed of non-combustion inorganic composite plates, and belongs to the technical field of the ventilation pipelines. The utility model is characterized in that an inner pipe and an outer pipe are respectively formed by the way that the non-combustion inorganic composite plates are connected with an interlayer angle type metal connector in an insertion way; a double-layer combined ventilation pipeline is formed by the way that the inner pipe and the outer pipe are sheathed; an air insulating layer is arranged between the inner pipe and the outer pipe. The utility model has the advantages of convenient installation, convenient maintenance, thermal insulation, heat preservation, corrosion resistance, fire resistance, etc., and is suitable for cold and warm ventilation air-conditioning systems.
Description
The utility model relates to a kind of changes in temperature ventilation equipment that air-conditioning system is ventilated that are used for, and belongs to the ventilation shaft technical field.
At present, the ventilation shaft of air-conditioning system galvanized iron sheet commonly used is made, and needs outsourcing heat-insulation layer and protective layer after the installation, has perishable, shortcomings such as fire protecting performance is poor, installation, maintenance inconvenience.
The purpose of this utility model is at above-mentioned weak point, provide a kind of corrosion-resistant, fire-retardant from put out that ability is good, installation, maintenance ventilation shaft easily, and this pipeline can reduce construction investment without insulation material.
The utility model is loaded among the outer tube by interior pipe box, constitutes double-layer combined ventilation shaft, and interior pipe, outer tube are plugged on the type metal plug connector of interlayer angle by the fireproof inorganic composite plate respectively to be formed.
The utility model, pipe can adopt the fireproof inorganic composite plate to carry out dottle pin with outer tube space in it, forms air heat insulating layer.
The utility model, the shape of cross section of ventilation shaft can be square or rectangular, and size and length can be made according to execution conditions, and interior pipe is a ventilation duct.
The utility model has following characteristics;
1, substitute galvanized sheet iron pipe, save steel, installation, maintenance is easy;
2, adopt the fireproof inorganic composite plate, humidity resistance is good, can be fire-retardant, and acid and alkali resistance, salt corrosion;
3, utilize the fireproof inorganic composite plate to separate inner and outer pipe, form air heat insulating layer,, reduce cost without insulation material.
The utility model can be widely used in the air-conditioning system in industrial buildings such as factory floor, hotel, restaurant, market, theater or mine, tunnel.
The utility model is described in further detail in conjunction with the accompanying drawings for following embodiment.
Fig. 1 is the cross-sectional structure figure of the utility model embodiment.
Fig. 2 is the perspective view of the utility model embodiment.
With reference to Fig. 1, Fig. 2, present embodiment is the rectangle ventilation shaft, constitute double-layer combined ventilation shaft among being set in outer tube 2 by interior pipe 1, interior pipe, outer tube are plugged on the interlayer angle type metal plug connector 4 by fireproof inorganic composite plate 3 respectively and form, the fireproof inorganic composite plate of interior pipe, outer tube correspondence constitutes the dottle pin in inner and outer pipe space, forms air heat insulating layer 5.The material that the fireproof inorganic composite plate 3 of present embodiment is made up of magnesia, magnesium chloride, glass cloth, talcum powder, sawdust etc. is made, and interlayer angle type metal plug connector 4 adopts stainless steel to make.
