Description

Connecting pipe for connecting turbocharged engine

Technical Field

Background

The automobile air inlet system guides air outside the automobile into the air inlet system through an air inlet, the air filter is used for filtering and purifying the introduced air, and the filtered cold air is guided into the turbocharged engine through the connecting pipe to be combusted. The temperature of the interface of the turbocharged engine and the air filter is high, about 170 ° to 180 °, so a rubber tube made of high temperature resistant material must be used to connect the air inlet of the turbocharged engine. Commonly used rubber materials are such as: the temperature that Ethylene Propylene Diene Monomer (EPDM), nitrile rubber (NBR) and polyvinyl chloride (PVC) blend can bear is lower than 170 degrees, and the blend can not be used for manufacturing the air inlet of the rubber pipe directly contacting with the turbocharged engine. The materials commonly used for manufacturing the rubber tube at present are as follows: ethylene acrylate rubber (AEM). The AEM material has excellent performance and can bear higher temperature, but the AEM material has higher price, and the cost of the rubber pipe made of the AEM material is doubled compared with that of the rubber pipe made of the common rubber material.

Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

Fig. 1-3 show a connecting tube for connecting a turbocharged engine, comprising: a rubber tube 100 and a high temperature resistant ring 200. An annular gap 110 is formed on the inner wall of one end of the rubber tube 100, and an annular groove 120 is formed on the circular arc surface close to the inner side in the annular gap 110. An annular bulge 210 is arranged on the outer peripheral surface of one end of the high temperature resistant ring 200, the annular bulge 210 is matched with the annular groove 120, and the outer peripheral surface and one end surface of the high temperature resistant ring 200 are abutted against the annular gap 110.

The rubber tube 100 can be fixedly connected with the high temperature resistant tube by matching the annular notch 110 with the annular groove 120. The high-temperature resistant pipe can be directly connected to a high-temperature connector of the turbocharged engine, so that the requirement of high-temperature resistance of the connecting pipe is met. In addition, since the rubber tube 100 is not in direct contact with the turbocharged engine, the pipe made of common rubber materials (such as Ethylene Propylene Diene Monomer (EPDM), nitrile rubber (NBR), and polyvinyl chloride (PVC)) can meet the working condition requirements. Most of the materials in the connecting pipe are common rubber, so that the cost of the connecting pipe is effectively reduced.

In this embodiment, the material of the refractory ring 200 is ethylene acrylate rubber (AEM). In other embodiments, the high temperature resistant ring 200 may be made of other rubber materials capable of withstanding a high temperature of 180 °.

In order to better connect the rubber tube 100 and the high temperature resistant ring 200, the rubber tube 100 and the high temperature resistant ring 200 are connected through a vulcanization process. The adoption of the vulcanization process can lead the rubber tube 100 and the high temperature resistant ring 200 to generate chemical changes, and the connection between the rubber tube 100 and the high temperature resistant ring is tighter. In addition, the performance of the original rubber material can be changed through a vulcanization process, so that the rubber material can meet the use requirement.

In this embodiment, the rubber tube 100 is corrugated in the axial direction. The corrugated rubber tube 100 can absorb the vibration of the equipment, and reduce the influence of the vibration of the equipment on the rubber tube 100.

In addition, the outer peripheral surfaces of both ends of the rubber tube 100 are respectively provided with an annular limiting ring 130, and the annular limiting rings 130 are used for fixing an external clamp. The annular limiting ring 130 can limit the connection position of the clamp, and connection failure caused by sliding of the clamp from the rubber tube 100 is avoided.

In the scheme, the rubber tube 100 is provided with a vent pipe 140 for connecting an external vent valve, the vent pipe 140 is communicated with the rubber tube 100, and the vent pipe 140 is an internal threaded pipe. The vent valve can be used to keep the air pressure in the connecting tube balanced, avoiding the creation of high pressure hazards. The vent pipe 140 adopts an internal thread structure, so that the vent valve can be conveniently connected, and meanwhile, the good sealing performance is achieved.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
