Abstract
The utility model relates to auto parts and components and manufactures processing technique field, the novel noise abatement valve block of a kind of Valve EGR concretely, comprise rubber skeleton and metal connected unit, it is characterized in that: rubber skeleton is in " work " font, the outside of the upper surface of rubber skeleton is provided with some convex grains, the inside of rubber skeleton upper surface adopts keyway arrangements to be connected with the upper surface of metal connected unit, the lower surface of metal connected unit and the inner tight of rubber skeleton lower surface are fitted, the outside central authorities of rubber skeleton lower surface are provided with boss, and boss is connected with Valve EGR.The utility model compared with prior art, valve block adopts rubber skeleton and metal connected unit to combine, significantly increase the working life of valve block, and be provided with some convex grains in the outside of the upper surface of rubber skeleton, avoid when valve block collides with valve body or collides with support in high speed folding and produce noise.
Description
Technical field
The utility model relates to auto parts and components and manufactures processing technique field, is the novel noise abatement valve block of a kind of Valve EGR concretely.
Background technique
Along with automobile widely using and developing in China, Consumer also progressively improves for the requirement of automobile product, such as power character, fuel economy, Security and travelling comfort.And criteria for noise is very important point in travelling comfort requirement.
In current automobile electronic fuel oil jet system, the noise of Valve EGR has become the important sources that in whole electric injection system, noise produces, effect and the working principle of Valve EGR are: produce in automotive oil tank, and the fuel-steam after canister adsorbing contaminant, under the control of engine operating requirements and Engine ECU, by the folding of solenoid valve valve in valve body, again feed back in engine intake manifold, and enter in engine cylinder together with fresh air and burn.
Existing Valve EGR is generally all made up of the Valve EGR in upper shell, lower shell body and upper and lower casing, all that Valve EGR is arranged on the Valve EGR support of car body during installation, the mechanism of production of its noise is the high speed folding due to valve block, cause the vibration of whole valve body different direction, and and produce between Valve EGR support on car body and collide, thus send and valve body vibration with noise frequently.Especially, when valve body working load is large, the noise of generation obviously will affect the travelling comfort of car load.
Designing a kind of can the valve block of noise reduction be very important for this reason.
Summary of the invention
The utility model breaches a difficult problem for prior art, devise a kind of can the valve block of noise reduction.
In order to achieve the above object, the utility model devises the novel noise abatement valve block of a kind of Valve EGR.Comprise rubber skeleton and metal connected unit, it is characterized in that: rubber skeleton is in " work " font, the outside of the upper surface of rubber skeleton is provided with some convex grains, the inside of rubber skeleton upper surface adopts keyway arrangements to be connected with the upper surface of metal connected unit, the lower surface of metal connected unit and the inner tight of rubber skeleton lower surface are fitted, the outside central authorities of rubber skeleton lower surface are provided with boss, and boss is connected with Valve EGR.
Described some convex grains are that center is to one-tenth distribution according to the center of rubber skeleton upper surface outside.
The utility model compared with prior art, valve block adopts rubber skeleton and metal connected unit to combine, significantly increase the working life of valve block, and be provided with some convex grains in the outside of the upper surface of rubber skeleton, avoid when valve block collides with valve body or collides with support in high speed folding and produce noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
See Fig. 2,1 is rubber skeleton, and 2 is metal connected unit, and 3 is convex grain, and 4 is boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See Fig. 2, the utility model devises the novel noise abatement valve block of a kind of Valve EGR, comprise rubber skeleton 1 and metal connected unit 2, rubber skeleton 1 is in " work " font, the outside of the upper surface of rubber skeleton 1 is provided with some convex grains 3, the inside of rubber skeleton 1 upper surface adopts keyway arrangements to be connected with the upper surface of metal connected unit 2, the lower surface of metal connected unit 2 and the inner tight of rubber skeleton 1 lower surface are fitted, the outside central authorities of rubber skeleton 1 lower surface are provided with boss 4, and boss 4 is connected with Valve EGR.
Some convex grains 3 described in the utility model are that center is to one-tenth distribution according to the center of rubber skeleton 1 upper surface outside, reduce collision area during valve block collision, also striking force is separated into some component simultaneously, adds the working life of valve block, can not valve block be broken.
In concrete enforcement, because valve block adopts rubber skeleton 1 and metal connected unit 2 to combine, significantly increase the working life of valve block, and be provided with some convex grains 3 in the outside of the upper surface of rubber skeleton 1, avoid when valve block collides with valve body or collides with support in high speed folding and produce noise, improve the travelling comfort of driving greatly.
