Abstract
The utility model relates to a soft air pipe for a rail vehicle air conditioning system, which comprises an air pipe body and an elastic element, wherein the elastic element is spirally arranged in the air pipe body; the cross section of the wind pipe body is in circular arc transition. The utility model relates to a soft tuber pipe for rail vehicle air conditioning system, under the elastic element's that oval-shaped air duct body and spiral were arranged cooperation, stability is good, and when the air duct body was crooked, its cross sectional dimension was unchangeable to the phenomenon that the part collapses can not appear.
Description
Technical Field
The utility model relates to a soft tuber pipe for rail vehicle air conditioning system. Belongs to the technical field of rail transit.
Background
The utility model discloses a branch blast pipe (application number: 200920037631) of air conditioning system, including the tuber pipe body, heat preservation, flange and sealed pad, be provided with the heat preservation in the outside of tuber pipe body, the tuber pipe body rivets with the flange rubber coating after, the flange bonds with sealed pad mutually, the tuber pipe body constitute by upper flame-retardant non-setting adhesive glass cloth, lower floor's flame-retardant non-setting adhesive glass cloth and spring wire, the spring wire is located between upper flame-retardant non-setting adhesive glass cloth and the lower floor's flame-retardant non-setting adhesive glass cloth.
Although the patent is a kind of soft air pipe, when in actual use, the spring on the two sides in the air pipe body is stressed unevenly, and the problem of local collapse exists.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a tuber pipe for rail vehicle air conditioning system.
The purpose of the utility model is realized like this:
a kind of soft air hose used for air conditioning system of the rail vehicle, its characteristic is: the air duct comprises an air duct body and an elastic element, wherein the elastic element is spirally arranged in the air duct body; the cross section of the wind pipe body is in circular arc transition.
Further, the elastic element is a wire spring.
Furthermore, a heat-insulating layer is arranged outside the air duct body.
Furthermore, the cross section of the wind pipe body is oval.
Furthermore, the elastic element is coated with flame-retardant adhesive glass cloth.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model relates to a soft tuber pipe for rail vehicle air conditioning system, under the elastic element's that oval-shaped air duct body and spiral were arranged cooperation, stability is good, and when the air duct body was crooked, its cross sectional dimension was unchangeable to the phenomenon that the part collapses can not appear.
Drawings
Fig. 1 is a schematic view of a flexible air hose for a rail vehicle air conditioning system according to the present invention.
Fig. 2 is a schematic view of the flexible wind pipe after bending.
Fig. 3 is a sectional view a-a of fig. 1.
Fig. 4 is a sectional view B-B of fig. 1.
In the figure:
the air duct comprises an air duct body 1, an elastic element 2, a flame-retardant adhesive glass cloth 3 and a heat-insulating layer 4.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-2, the utility model relates to a soft air pipe for a rail vehicle air conditioning system, which comprises an air pipe body 1 and an elastic element 2, wherein the elastic element 2 is spirally arranged in the air pipe body 1, the elastic element 2 is a steel wire spring, the spirally arranged elastic element 2 can not only serve as a framework support for the air pipe body 1, but also the cross-sectional dimension is not changed when the air pipe body 1 is bent, and meanwhile, the phenomenon of local collapse cannot occur;
the heat preservation layer 4 is arranged outside the air duct body 1, and under the action of the heat preservation layer 4, condensed water generated due to temperature difference can be avoided.
Referring to fig. 3, the cross section of the air duct body 1 is oval, the end of the air duct body 1 is in arc transition, and compared with the olive shape in the prior art, the end of the air duct body 1 is uniform in stress and good in stability during bending.
Referring to fig. 4, the elastic element 2 is coated with a flame-retardant adhesive glass cloth 3.
The utility model relates to a hose for rail vehicle air conditioning system, under the cooperation of the elastic element 2 that oval-shaped air duct body 1 and spiral were arranged, stability is good, and when air duct body 1 was crooked, its cross-sectional dimension was unchangeable to the phenomenon that the part collapsed can not appear.
In the above embodiments, the present invention has been described only by way of example, but various modifications may be made by those skilled in the art after reading the present patent application without departing from the spirit and scope of the invention.
