Abstract

The utility model discloses a kind of boosters into return pipe assembly structure, the booster (5) is equipped with water inlet pipe (1) and return pipe (2), water inlet pipe (1) and return pipe (2) are welded on a connecting flange (3) by the booster into return pipe assembly structure, and formation is pressurized into return water pipe assembly (4).By adopting the above technical scheme, installation step is reduced, amount of parts and management workload are reduced, saves production cost；It is more relatively reliable than the leakproofness of copper gasket using the sealing of steel form of packers, it is more stable to the protection of engine.

Description

A kind of booster is into return pipe assembly structure

Technical field

The utility model belongs to the technical field of Vehicle Engine Structure design and development.More specifically, the utility model It is related to a kind of booster into return pipe assembly structure.

Background technique

Engine supercharger water inlet pipe and return pipe are pipelines cooling in booster operational process, prevent booster by The damage of high-temperature exhaust air is the important ring in entire cooling system.

The common booster water inlet pipe of the prior art and backwater pipe structure are as shown in Figure 1 and Figure 2.

Booster water inlet pipe 1 used at present and return pipe 2 are single pipe fitting, are tightened in booster by hollow bolt On, it is sealed between 5 ontology of water inlet pipe 1 and return pipe 2 and booster by seal washer.

The step of water inlet pipe and return pipe assembly of this structure, is more, and leakproofness is unstable.

Summary of the invention

The utility model provides a kind of booster into return pipe assembly structure, and the purpose is to reduce the workload of assembly.

To achieve the goals above, the technical solution that the utility model is taken are as follows:

The booster of the utility model is equipped with water inlet pipe and return pipe into return pipe assembly structure, the booster, Water inlet pipe and return pipe are welded on a connecting flange by the booster into return pipe assembly structure, formation be pressurized into return Water pipe assembly.

Between the connecting flange and the contact surface of booster ontology, gasket seal is set.

The gasket seal is steel gasket seal.

The surface of the gasket seal is equipped with coating for protection against corrosion or corrosion-inhibiting coating.

The utility model by adopting the above technical scheme, reduces installation step, reduces amount of parts and management workload, section About production cost；It is more relatively reliable than the leakproofness of copper gasket using the sealing of steel form of packers, more to the protection of engine Stablize.

Detailed description of the invention

Label in content and figure shown in attached drawing is briefly described as follows:

Fig. 1 is the supercharger structure schematic diagram of the prior art；

Fig. 2 is the structural schematic diagram of the booster of the prior art, return pipe；

Fig. 3 is the structural schematic diagram of the utility model.

In the figure, it is marked as

1, water inlet pipe, 2, return pipe, 3, connecting flange, 4, be pressurized into return water pipe assembly, 5, booster.

Specific embodiment

Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed Thin explanation, with help those skilled in the art to the inventive concept of the utility model, technical solution have it is more complete, accurate and Deep understanding.

The structure of the utility model as shown in Figure 3 is a kind of booster into return pipe assembly structure, the booster 5 It is equipped with water inlet pipe 1 and return pipe 2.

In order to overcome the shortcomings of the prior art, realizing the goal of the invention for reducing the workload of assembly, the utility model The technical solution taken are as follows:

As shown in figure 3, water inlet pipe 1 and return pipe 2 are welded on by the booster of the utility model into return pipe assembly structure On one connecting flange 3, formation is pressurized into return water pipe assembly 4.

Between the contact surface of 3 ontology of the connecting flange 3 and booster, gasket seal is set.

The utility model it is above-mentioned it is improved be pressurized into return water pipe assembly, be by the way that water inlet pipe 1 and return pipe 2 to be welded on On one connecting flange 3, formation is pressurized into return water pipe assembly 4, then by it when installing on booster 5, in its contact surface Between install a gasket seal, guarantee coolant liquid do not reveal.The technical solution of the utility model reduces installation step, reduces zero Number of packages amount and the workload of management, have saved production cost.

The gasket seal is steel gasket seal.The sealing of steel form of packers more may be used than the leakproofness of copper gasket It leans on, it is more stable to the protection of engine.

The surface of the gasket seal is equipped with coating for protection against corrosion or corrosion-inhibiting coating.The effect of coating for protection against corrosion or corrosion-inhibiting coating is Antirust and protection to gasket seal, and so that the sealing effect is better.

Jiangxi Teng Le Dynamics Co., Ltd 3M12 turbocharged engine, it is total into return pipe using the booster of this structure At reduction installation step optimizes engine structure, ensure that the performance of cooling system, facilitates the management of components.

The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model Protection scope within.
