Abstract
The utility model relates to a booster midbody and diffuser plate sealing mechanism. The annular ring-shaped diffusion plate comprises an intermediate body and a diffusion plate, wherein one end of the intermediate body adjacent to the diffusion plate is provided with an annular bulge, one surface of the diffusion plate corresponding to the annular bulge is provided with an annular surrounding table, and the annular surrounding table surrounds the annular bulge. It features that a flexible sealing ring is arranged between the annular boss and the pressure-expanding plate. By adopting the sealing mechanism, the maintenance is convenient, and the production efficiency and the sealing effect can be improved.
Description
Technical Field
The utility model relates to a mechanical seal mechanism. In particular to a sealing mechanism between an automobile supercharger intermediate body and a diffuser plate.
Background
In the automobile supercharger production industry, it is known that in order to prevent the engine oil in the intermediate oil passage of the supercharger from leaking, the intermediate and the diffuser plate must be sealed. The traditional sealing mode is to compound a layer of rubber film on one end face of the intermediate body adjacent to the diffuser plate. Although the sealing between the intermediate body and the pressure-expanding plate can be realized by compounding a layer of rubber film on the end face of one end of the intermediate body adjacent to the pressure-expanding plate, the rubber film is compounded on the end face of the intermediate body and is coated manually. And manual operation, not only production efficiency is low, still can not guarantee the homogeneity of coating for sealed effect is poor. And because a layer of rubber film is formed on the end face of the intermediate body by adopting a coating mode, the rubber film is easy to fall off during maintenance. Therefore, the rubber film needs to be coated once after the assembly and disassembly, and the maintenance is troublesome.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the utility model is to provide a booster midbody and diffuser plate sealing mechanism. By adopting the sealing mechanism, the production efficiency is high, the sealing effect is good, and the maintenance is convenient.
The utility model discloses the above-mentioned problem that solves is realized by following technical scheme:
the utility model discloses a booster midbody and diffuser plate sealing mechanism, including midbody and diffuser plate, the midbody one end adjacent with the diffuser plate has annular arch, and the diffuser plate corresponding with annular arch has the annular to enclose the platform in one side, the annular encloses the platform and surrounds in the protruding outside of annular. It features that a flexible sealing ring is arranged between the annular boss and the pressure-expanding plate.
The diameter of the outer circle and the diameter of the inner circle of the flexible sealing ring are the same as the diameter of the outer circle and the diameter of the inner circle of the annular bulge respectively. The flexible sealing ring is a rubber gasket.
According to the scheme, the flexible sealing ring is arranged between the annular bulge and the diffuser plate. During installation, manual operation is not needed, and compared with the background technology, the sealing effect of the production efficiency is greatly improved. And because the end face of the intermediate body is provided with the flexible sealing ring to realize the sealing effect, the maintenance only needs to replace the flexible sealing ring, and compared with the prior art that the flexible sealing ring is disassembled and assembled once and needs to be coated with a rubber film once, the maintenance is very convenient.
Drawings
Fig. 1 is a schematic view of a sealing mechanism of a supercharger intermediate and a diffuser plate according to the present invention.
Detailed Description
As shown in fig. 1, the intermediate body and the diffuser plate sealing mechanism of the present invention includes an intermediate body 5 and a diffuser plate 4. An annular bulge 2 is processed at one end of an intermediate body 5 adjacent to the diffuser plate 4, an annular surrounding table 1 is processed on one surface of the diffuser plate 4 corresponding to the annular bulge 2, and the annular surrounding table 1 surrounds the annular bulge 2. A flexible sealing ring 3 is arranged between the annular bulge 2 and the diffusion plate 4.
The diameter of the outer circle and the diameter of the inner circle of the flexible sealing ring 3 are the same as the diameter of the outer circle and the diameter of the inner circle of the annular bulge 2 respectively.
The flexible sealing ring 3 is a rubber gasket.
