Abstract

The invention discloses a cold and hot air guide pipe, which mainly comprises a rubber layer, a basic frame, an inner fabric layer, an outer fabric layer and a reinforcing layer. The rubber layer and the inner fabric layer are sequentially covered outside a guide pipe body, the basic frame is wound outside the inner fabric layer helically, the outer fabric layer is adhered to the outer surface of the basic frame, and the reinforcing layer is wound on the outer fabric layer among different turns of the basic frame to prevent the outer fabric layer from shifting or falling off during use. The cold and hot air guide pipe can be used for delivering cold and hot air in environments with high or low temperature and under high pressure of 1Mpa.

Description

A kind of cold and hot airflow duct

Technical field

The present invention relates to a kind of honeycomb duct, specifically a kind of cold and hot airflow duct can be carried cold and hot air in high and low temperature environment and under the high pressure of 1MPa.

Background technique

At present; The honeycomb duct of the common cold and hot air of conveying is that general purpose rubber folder cotton fabric is processed; Or general purpose rubber folder RIPSTOP processes, and the technological deficiency that aforementioned honeycomb duct exists is: (1) since the restriction of material can't under high and low temperature and high-pressure environment, work; When (2) under the high and low temperature environment, using, be prone to hardening, become fragile, cause that adhesive plaster is aging, produce be full of cracks, making lost efficacy accelerates the lost of life; (3) the honeycomb duct sealability is not enough, can't bear too high air pressure, when bearing highpressure, can produce gas leak phenomenon.

Summary of the invention

For solving the problems of the technologies described above, the object of the present invention is to provide a kind of cold and hot airflow duct, can carry cold and hot air in high and low temperature environment and under the high pressure of 1MPa.

The present invention is achieved through following technological scheme.

The present invention mainly is made up of rubber layer, basic framework, interior fabric layer, outer fabric layer and back-up coat; Outside the honeycomb duct body, be with rubber layer and interior fabric layer successively; Interior fabric is outer to be wound with basic framework with spiral fashion; The basic framework outer surface is pasted with outer fabric layer, and back-up coat is wrapped on the outer fabric layer between every this skeleton of cycle basis, to prevent that moving and obscission from use appearring in outer fabric layer.

Said rubber layer is a silicone rubber; Said basic framework is an elastic member, can be spring or bellows; Fabric layer is the silica gel gummed cloth in said, is processed by silicone rubber and aramid fiber silk fabric; Said outer fabric layer is the aramid fiber silk fabric; Said back-up coat is an aramid line.

Compared with prior art; The beneficial effect that the present invention reaches is: 1. the honeycomb duct body is with rubber layer outward among the present invention, can play seal action, makes honeycomb duct can under certain pressure, carry out work; And the phenomenon that can not leak air can be born 1Mpa air pressure and air tight; 2. the basic framework among the present invention has played the support effect, makes honeycomb duct not yielding; 3. the inside and outside fabric layer among the present invention is a protective layer, can prevent that honeycomb duct from use wearing and tearing; 4. the raw material that each constituent elements adopts among the present invention are silicone rubber, aramid fiber silk fabric and aramid line etc., and product can be worked in-60 ℃～+ 250 ℃ temperature ranges, has improved working life; 5. the present invention has good sheathed, can be used to connect the product of different amount.

Fig. 1 is a structural drawing of the present invention;

Fig. 2 be among Fig. 1 A-A to profile.

Among the figure: 1-basic framework, fabric layer in the 2-honeycomb duct body, 3-, the outer fabric layer of 4-, 5-back-up coat.

Embodiment

Below through embodiment's form; Content of the present invention is done further explain; But the scope that should at this point not be interpreted as theme according to the invention only limits to following embodiment; Do not breaking away under the above-mentioned technological thought situation of the present invention, all various modifications, replacement and changes of making according to ordinary skill knowledge and customary means include within the scope of the invention.

Fig. 1 and Fig. 2 are respectively that structural drawing of the present invention and A-A are to profile; The present invention mainly is made up of rubber layer 2, basic framework 1, interior fabric layer 3, outer fabric layer 4 and back-up coat 5; Outside the honeycomb duct body, be with rubber layer 2 and interior fabric layer 3 successively; Be wound with basic framework 1 with spiral fashion outside the interior fabric layer 3; Basic framework 1 outer surface is pasted with outer fabric layer 4, and back-up coat 5 is wrapped in and prevents on the outer fabric layer 4 of 1 on every this skeleton of cycle basis that moving and obscission from use appearring in outer fabric layer 4.

Said rubber layer 2 is a silicone rubber; Said basic framework 1 is an elastic member, can be spring or bellows; Fabric layer 3 is the silica gel gummed cloth in said, is processed by silicone rubber and aramid fiber silk fabric; Said outer fabric layer 4 is the aramid fiber silk fabric; Said back-up coat 5 is an aramid line.
