Abstract
The utility model relates to the ventilating pipe technical field, in particular to the ventilating pipe for the central air conditioner technical field. The utility model comprises ventilating pipes consisting of inner layers, outer layers and thermal insulation layers which all are compounded by the magnesium oxide and the magnesium chloride materials and are strengthened by the no-alkali and medium-alkali fiber cloth, the ventilating pipes which are in muff coupling with each other are the direct pipes without flange sides or the steel tubing in different shapes. The utility model has a good connection effect and is easy to be assembled; in addition, the pipes can be freely cut to a rational length on the spot according to the specification and length of the building, as a result which, the utility model has the advantages of time saving and quick and convenient assembly, and can save half of time.
Description
The utility model relates to ventilating uses the Manifold technology field, relates in particular to central air-conditioner ventilation duct technical field.
Along with improving constantly of people's living standard, when people in use entreat air-conditioning, need with ventilation duct as the air channel, at present, the airduct that generally uses when central air-conditioner is installed is synthetic with materials such as magnesium oxide and magnesium chlorides, alkali-free and medium alkali fiber cloth add pretends the middle thermal insulating material that is provided with of internal and external layer, the ventilation duct of forming, the two ends of its ventilation duct are provided with flange, be connected into ventilation duct by flange by the Luo silk between ventilation duct and the ventilation duct, this ventilation duct is because the two ends of its pipe are provided with flange, cause qualification, can not must have the ventilation duct of different length according to the different structure in each house made to order according to different instant installation of each building structure to the length of ventilation duct own, wasted the time, waste material; In use the noise that main frame, wind speed caused there is not erasure effect; In addition, because composite material is by slight dewfall, anti-fontanel phenomenon, the ventilation duct surface is not attractive in appearance.
The purpose of this utility model provides a kind of above-mentioned defective that overcomes, convenient and quick construction, and sound-absorbing effect is good, and is specious, and the ventilation duct that can increase the service life.
The technical solution of the utility model is achieved in that
The utility model comprises by magnesium oxide and magnesium chloride material synthetic, by alkali-free and in alkali fiber cloth strengthen the ventilation duct formed as internal and external layer and thermal insulation layer, it is characterized in that, ventilation duct be can't blue limit straight tube or steel tubing in different shapes, adopt socket between ventilation duct and the ventilation duct.
Socket and outer hub or the directly outer socket of employing in socket is adopted.
Interior socket is that ventilation duct is connected this link with the ventilation duct joint by metal connecting piece and is T type shape, establishes sleeve pipe in the joint; Outer socket is directly to adopt the sleeve pipe socket in the tube and tube joint.
Ventilation duct internal layer composite flame-proof high density polyethylene quieter material, ventilation duct outer surface clad aluminum foil glass cloth.
The utility model advantage is:
1, owing to adopting socket tube and tube good connecting effect without the flange connection between the tube and tube, the length of airduct can be selected arbitrarily according to the house specification when installing and using, on-site cutting, outer hub in adopting, easy for installation and minimizing installation time 1/2.
2, since on internal layer the compound fire-retardant high density polyethylene of one deck, significantly reduced noise.
3, surface recombination aluminium foil glass cloth increases the anti-aging of airduct, has prolonged working life, and beautiful shape.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is connection diagrams in the utility model tube and tube.
Accompanying drawing 3 is T bar material metal connecting piece structural drawing.
1 is aluminium foil layer among the figure, the 2nd, and composite material, the 3rd, thermal insulation layer, the 4th, composite material (layer), the 5th, quieter material (layer), the 6th, sleeve pipe.
Introduce embodiment in conjunction with the accompanying drawings:
As shown in the figure, the utility model is that the flange with existing ventilation duct two ends removes and is straight tube or is steel tubing in different shapes, connection between the tube and tube can be fixed by metal connecting piece, this link is the ⊥ shape, also can adopt the ⊥ structural section to connect, and fix by screw, be provided with in the joint by the compound outer sleeve of inorganic material; Or the two directly adopts the sleeve pipe socket between two ventilation ducts.
The fire-retardant highly dense polythene quieter material 5 of the compound one deck of ventilation duct internal layer, the compound one deck aluminium foil of its outer surface glass cloth 1.
Claims (4)
1, a kind of composite ventilated pipe, it comprises by magnesium oxide and magnesium chloride material synthetic, by alkali-free and in alkali fiber cloth strengthen the ventilation duct formed as internal and external layer and thermal insulation layer, it is characterized in that, ventilation duct be can't blue limit straight tube or steel tubing in different shapes, adopt socket between ventilation duct and the ventilation duct.
2, composite ventilated pipe according to claim 1 is characterized in that, socket and outer hub or the directly outer socket of employing in said socket is adopted.
3, composite ventilated pipe according to claim 2 is characterized in that, said interior socket is that ventilation duct is connected by metal connecting piece with the ventilation duct joint, and this link is T type shape, establishes sleeve pipe in the joint; Outer socket is directly to adopt the sleeve pipe socket in the tube and tube joint.
4, composite ventilated pipe according to claim 1 is characterized in that, ventilation duct internal layer composite flame-proof high density polyethylene quieter material, ventilation duct outer surface clad aluminum foil glass cloth.
