Abstract
The invention relates to a throttle valve sheet for an electrospray throttle valve body. The throttle valve sheet comprises a body, wherein the body is provided with a circle of which two sides are planes; two symmetrical holes are formed at a position of the diameter of the circle; two symmetrical salient points are arranged on one side of the diameter of the circle; and the body is made of polyxymethylene engineering plastics or polypropylene glycol adipate (PPA) engineering plastics produced by DuPont Company or polyamide66 (PA66) engineering plastics produced by DuPont Company. The throttle valve sheet has the advantages that: the excircle dimension and form tolerance of the throttle valve sheet can be guaranteed through one-step injection molding, engineering plastics of lubricating materials are increased, abrasion between the throttle valve sheet and a shell is reduced, and the service life of the product is prolonged.
Description
Technical field
The present invention relates to a kind of EFI throttle valve body, relate in particular to the throttle blade that is used for the EFI throttle valve body.
Background technique
The effect that is used for the throttle blade of EFI throttle valve body is to hinder flowing of air, is fastened on the throttle plate pin by screw, is following throttle plate pin and is rotating together, by the air mass flow of the angle decision closure that rotates.Throttle blade and valve housing intracoelomic cavity Spielpassung, when throttle plate pin rotated, throttle blade and interior cavity gap increase gradually controlled the flow that air passes through from inner chamber.
As Fig. 1, Fig. 2, shown in Figure 3: among the figure: the cylindrical 3 of throttle blade 8 contacts with throttle valve body housing inner chamber 4, throttle blade 8 locate two salient points 1 as spacing usefulness, be stuck on the throttle plate pin 5, the hole 2 of throttle blade 8 is corresponding with tapped hole 6 places of throttle plate pin 5 neat, and it is fastening with screw, throttle blade 8 is rotated with throttle plate pin 5, and cylindrical 3 increases gradually with the gap of valve housing intracoelomic cavity 4.
The used throttle blade material of electronic throttle valve body is selected Cuprum alloy or aluminum alloy usually for use in the prior art, and metal throttle blade in the past is by the plate stamping moulding, and the two sides is the plane.
In processing, carry out the punching press profile earlier, and then fine finishing cylindrical, this processing method technological process is long, critical process all wants fine finishing and operation to guarantee the ability height, otherwise can bring following problem: can produce burr and overlap during impact briquetting, planeness also can descend, and these stamping defects can increase mechanical processing difficulty; And machining will guarantee excircle dimension and figure tolerance simultaneously, if reach requirement the sealing between throttle blade and the housing inner chamber descended, and metal adds and can bring burr man-hour, and these burrs directly influence the flexibility of throttle blade when rotating.Because metal friction when rotating between the two because the difference of metal skin hardness can cause the wearing and tearing aggravation, influences the life-span of product.
The PA66 engineering plastics that PPA engineering plastics that engineering plastics POM of the prior art (polyoxygenated polyoxymethylene) or E.I.Du Pont Company produce or E.I.Du Pont Company produce have obtained application in other field, and how they being applied in throttle blade is that the technician will consider.Wherein the composition of PPA engineering plastics and PA66 engineering plastics can from
Www.plastics.dupont.comObtain on the website.
The technical issues that need to address of the present invention have provided a kind of throttle blade that is used for the EFI throttle valve body, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: body; Described body is a circle that the two sides is the plane; The hole of two symmetries is set in the diameter of a circle position; The salient point of two symmetries is set in diameter of a circle one side; The material of described body is the PPA engineering plastics of polyoxygenated polyoxymethylene engineering plastics (POM) or E.I.Du Pont Company's production or the PA66 engineering plastics that E.I.Du Pont Company produces.
Compared with prior art, the invention has the beneficial effects as follows: an injection moulding just can guarantee throttle blade excircle dimension and figure tolerance; The engineering plastics of increase lubriation material have reduced the wearing and tearing between throttle blade and the housing, have increased the life-span of product.
Description of drawings
Fig. 1 is the throttle blade structural representation;
Fig. 2 is the structural representation that combines with valve body among Fig. 1;
Fig. 3 be among Fig. 2 A-A to view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: body 8; Described body 8 is circles 3 that a two sides is the plane; The hole 2 of two symmetries is set in the diametrical position of circle 3; The salient point 1 of two symmetries is set in diameter one side of circle 3; The material of described body is the PPA engineering plastics of polyoxygenated polyoxymethylene engineering plastics (POM) or E.I.Du Pont Company's production or the PA66 engineering plastics that E.I.Du Pont Company produces.
The present invention has lubricating function owing to selected engineering plastics for use, has reduced between throttle blade and the housing and has worn and torn, and can guarantee the sealing of throttle blade cylindrical and throttle valve body housing inner chamber, has increased the life-span of product.
The present invention replaces original Cuprum alloy or aluminum alloy with engineering plastics, since precise injection molding, the traditional processing mode before closure processing changes, and an injection moulding just can guarantee throttle blade excircle dimension and figure tolerance.
