Abstract

The utility model relates to a heat insulation ventilating duct and a connecting interface. The wall of the ventilating duct is composed of an outer wall of the ventilating duct made of inorganic glass fibre reinforced plastics, an inner wall of the ventilating duct made of fibre cloth and a heat insulation layer made of centrifugal glass wool. The heat insulation layer is arranged between the inner and the outer walls of the ventilating duct and is made into one body with the inner and the outer walls of the ventilating duct. An H-shaped connecting interface is used by the butt-joint of the ports of the ventilating ducts. The utility model has the advantages that the acid and alkali corrosion proof performance is good and the service life is long; the heat insulation effect is good and the generation of the secondary noise is avoided; the design of the connecting interface of the ventilating duct enables the phenomenon of fluid leakage to be avoided; the effects of burning resistance and water leak prevention are good.

Description

Almightiness type ventilation duct and connection interface

The utility model relates to a kind of insulation ventilation duct and connection interface, belongs to F16L9/14, F16L23/02 field in the international classifiation table.

Background technique of the present utility model: at present, the structure of the ventilation duct that adopt in the ventilation field is: inwall is an iron sheet structure, reinforces thermal insulation layer then thereon.It is not enough point: the one, not antiacid, caustic corrosion, life-span be short, generally at 3--8; The 2nd, thermal and insulating performance is undesirable; The 3rd, itself does not have acoustical absorptivity the iron sheet airduct, under certain wind speed, easily produces the secondary noise; The 4th, T font connection interface makes the pipeline joint easily produce the leakage current body and runs the leakage phenomenon.

Purpose of design of the present utility model: avoid the deficiency in the background technique, designing a kind of one is that antiacid, caustic corrosion, life-span are long; The 2nd, good effect of heat insulation; The 3rd, do not produce the secondary noise; The 4th, conveniently dock and can avoid running Lou the Almightiness type ventilation duct and the connection interface of phenomenon.

Design proposal of the present utility model: the inwall of air duct wall is made of fibre cloth (as glass fibre cloth), and purpose is: under the prerequisite with antiacid, caustic corrosion, fire-retardant, water leakage, avoid the secondary generating noise.Centrifugally glass-wool is as the purpose of insulation layer: it not only has good heat insulating effect, and antiacid, alkali, and is fire-retardant.The purpose of FRIM or sheet iron or the material ventilation duct outer wall that constitutes with the spraying of glass fibre cloth and gypsum is: have good tension, anti-folding, anti-collision strength, and fire-retardant, percolation-proof effect good.Connection interface adopts the purpose of I shape to be: under guaranteeing prerequisite stable and reliable for performance, avoided the race phenomenon of pipeline inner fluid.Its organization plan: Almightiness type ventilation duct and connection interface, it comprises pipeline (1), connection interface (2) is I-shaped structure, the ventilation duct outer wall (3) that the wall of ventilation duct (1) is made of FRIM or sheet iron or glass fibre cloth and gypsum spraying structure, the insulation layer (4) that ventilation duct inwall (5) that fibre cloth (as glass fibre cloth) constitutes and centrifugally glass-wool constitute constitutes, the insulation layer is positioned at ventilation duct, be made as one between outer wall and with the ventilation duct inside and outside wall, ventilation duct and the docking structure of ventilation duct port are that the conduits wall of ventilation duct adopts the I shape connection interface to be connected with the conduits wall of ventilation duct.

The utility model is compared with background technique, and the one, structural design novelty, uniqueness, simple; The 2nd, antiacid, the caustic corrosion performance is good, the life-span is long; The 3rd, good effect of heat insulation and avoided the secondary generating noise; The 4th, the design of ventilation duct connection interface has not only guaranteed its join strength and reliability, and the fluid of having avoided occurring in the connection interface butt joint in the background technique runs the leakage phenomenon; The 5th, fire-retardant, percolation-proof effect good; The 6th, cost is low, is easy to promote.
