Abstract
The utility model discloses a whole car is experimental with tail gas collection connecting pipe, the connecting pipe is straight tube or return bend, and it includes: the connecting pipe comprises an inner layer, an intermediate layer and an outer layer, wherein the intermediate layer is arranged between the inner layer and the outer layer, the inner layer of the connecting pipe is made of scale iron and is directly connected with the exhaust pipe when in use, and the connecting pipe is hard, is not easy to wear and has long service life; the middle layer is made of asbestos and wraps the inner layer of scale iron, so that heat transferred by the exhaust pipe is isolated, and operators are prevented from being scalded; outer layer material is fish scale iron, and the fixed asbestos of parcel strengthens the exterior structure, prevents that operation process from to the asbestos wearing and tearing, and increase of service life is applicable to different angle automobile exhaust pipes, and the commonality is stronger.
Description
Technical Field
The utility model relates to a whole car is experimental technical field, concretely relates to whole car is experimental with tail gas collection connecting pipe.
Background
With the rapid development of science and technology, the requirements of automobile users on the performance of vehicles are higher and higher, an emission test is an indispensable test in the automobile development stage, and an exhaust emission test is one of important tests for testing the performance of automobiles. In the whole vehicle test process, collecting tail gas is an important step in the whole test process, and the two main reasons are as follows: firstly, analyzing tail gas after a test; secondly, handle tail gas, prevent the polluted environment, prevent to harm operating personnel health, the automobile exhaust pipe's angle, the shape are various, and it is very high to the connecting device requirement between automobile exhaust pipe and the tail gas collector.
The existing connecting device adopts the rubber material for pipe connection, the heat resistance of the rubber material is poor, the texture is soft, the connecting device is used for a long time, weathering and abrasion are fast, the connecting device needs to be changed regularly, after the test is completed, operators can be scalded easily, under the high-temperature environment and long-term use, the damage speed is fast, the connecting device needs to be changed irregularly, the automobile exhaust pipe is used for a long time, the ironing can be realized, the disassembly after the test is completed is inconvenient, and the tail gas collection is that the whole automobile test must be collected.
Disclosure of Invention
The utility model discloses a problem that exists in the prior art has been designed a whole tail gas collection connecting pipe for car test, is used for different angle blast pipes, adopts fish scale iron and asbestos material structure, and fish scale iron texture is hard on the contrary, difficult wearing and tearing, long service life; asbestos material heat-proof quality is better, avoids experimental completion back scald operating personnel.
Realize the utility model discloses a technical scheme be, a whole car is experimental with tail gas collection connecting pipe, characterized by, it includes: the inner layer 3, the middle layer 4 and the outer layer 5, the middle layer 4 is arranged between the inner layer 3 and the outer layer 5, and the middle layer 4 is made of asbestos.
Further, the inner layer 3 and the outer layer 5 are made of fish scale iron.
Furthermore, the connecting pipe is a straight pipe or an elbow pipe.
The utility model relates to a whole car is experimental with beneficial effect of tail gas collection connecting pipe embodies:
according to the tail gas collecting connecting pipe for the finished automobile test, the scale iron is used as an inner layer structure, so that the connecting pipe is not easy to wear, and the service life is prolonged; the middle layer adopts an asbestos structure, so that the heat insulation effect is good, and operators cannot be scalded; the outer layer adopts the fish scale iron structure, and fixed intermediate level asbestos strengthens the exterior structure, and increase of service life saves connecting piece consumption cost, is applicable to different angle automobile exhaust pipe, and the commonality is stronger.

Detailed Description
The present invention will be described in further detail with reference to the accompanying fig. 1-3, and the embodiments described herein are only used for explaining the present invention, and are not used to limit the present invention.
As shown in the attached fig. 1-3, a tail gas collecting connecting pipe for a whole vehicle test, the connecting pipe is a straight pipe or a bent pipe, and comprises: inlayer 3, intermediate level 4, outer 5 inlayer 3 and outer 5 between set up intermediate level 4, inlayer 3 and outer 5 material be fish scale iron, intermediate level 4 material be the asbestos.
As shown in attached figure 1, the tail gas collecting connecting pipe for the whole vehicle test is a straight pipe and is used for connecting the vehicle with the exhaust pipe being a straight pipe; as shown in the attached drawing 3, the tail gas collecting connecting pipe for the whole vehicle test in another form is a bent pipe, is used for a vehicle with an exhaust pipe bent downwards, and is high in universality; the inner layer 3 of the connecting pipe, which is a straight pipe or a bent pipe, is made of scale iron, and is directly connected with the exhaust pipe when in use, so that the connecting pipe is hard, is not easy to wear and has long service life; the middle layer 4 is made of asbestos and wraps the inner layer of scale iron to isolate heat transferred by the exhaust pipe and prevent scalding operators; outer 5 materials are fish scale iron, wrap up fixed asbestos, make its inlayer structure of laminating completely, and the parcel is tight, strengthens the exterior structure simultaneously, prevents that operation process from wearing and tearing to asbestos, increase of service life.
When the test is carried out, a tail gas connecting piece is selected according to the angle of an automobile exhaust pipe, one end of the tail gas connecting piece is arranged on an exhaust pipeline, and the other end of the tail gas connecting piece is arranged on a pipeline of a tail gas collector; when the performance test of the whole vehicle is carried out, the tail gas is collected, so that the tail gas is mainly prevented from polluting an environmental bin and causing physical damage to operators, and the tail gas needs to be analyzed in part of tests; and after the tail gas is collected, the connector is disassembled, and the test is completed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
