Preferably, in the above-mentioned flange, said reinforcement space is arranged at the intersection of the flanged surface and the sidewall of said flange.
Preferably, in the above-mentioned flange, said reinforcement space is that the flanged surface and the outer side wall of said flange is connected to form through median surface.
Preferably, in the above-mentioned flange, said median surface specifically is a sphenoid surface.
Preferably, in the above-mentioned flange, be provided with said reinforcement space around the said flanged surface.
Preferably, in the above-mentioned flange, said reinforcement space and said bolt hole intersect.
A kind of gas exhaust manifold structure comprises gas exhaust manifold and the flange that is arranged on the pipe end of gas exhaust manifold, and said flange is specially above-mentioned each described flange.
Preferably, in the above-mentioned gas exhaust manifold structure, said flange and said gas exhaust manifold are integral structure.
The utility model provides the flanged surface of flange to be provided with the reinforcement space; The certain area of flanged surface of flange of wherein having strengthened volume exclusion makes the area of flanged surface reduce, when the flanged surface of this flange and gasket seal or other junction surface compress; Area of contact reduces; Lifting surface area diminishes, interaction force one timing between flanged surface and gasket seal or other junction surface, and lifting surface area is less; So the intensity of pressure that flanged surface and gasket seal or other junction surface receive is bigger, make that sealing effect between the two is better.
In order to reach above-mentioned second purpose, the utility model also provides a kind of gas exhaust manifold structure, and this gas exhaust manifold structure comprises above-mentioned any flange.Because above-mentioned flange has above-mentioned technique effect, the gas exhaust manifold structure with this flange also should have the corresponding techniques effect.
In sum, the flange that the utility model provided can solve the relatively poor problem of sealing effect between flanged surface and the gasket seal effectively.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the utility model; Employed accompanying drawing is made brief account in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the gas exhaust manifold structure that provides among the utility model embodiment and the structural representation of flange thereof;
Fig. 2 is the gas exhaust manifold structure that provides among the utility model embodiment and the sectional view of flange thereof.
Mark is following in the accompanying drawing:
1-gas exhaust manifold, 2-flange, 21-flanged surface, 22-sphenoid surface, 23-bolt hole.
Embodiment
In order further to understand the utility model; Below in conjunction with embodiment the utility model preferred implementation is described; Describe just in order to further specify the feature and advantage of the utility model but should be appreciated that these, rather than to the restriction of the utility model claim.
First purpose of the utility model is to provide a kind of flange; The structural design of this flange can solve the relatively poor problem of sealing effect between flanged surface and the gasket seal effectively, and second purpose of the utility model provides a kind of gas exhaust manifold structure that comprises above-mentioned flange.
To combine the accompanying drawing among the utility model embodiment below, the scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiments that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides the flanged surface 21 of flange to be provided with the reinforcement space; The certain area of flanged surface 21 of flange of wherein having strengthened volume exclusion makes the area of flanged surface 21 reduce, when the flanged surface 21 of this flange compresses with gasket seal or other junction surface; Area of contact reduces; So lifting surface area diminishes, interaction force one timing between flanged surface 21 and gasket seal or other junction surface, lifting surface area is less; So flanged surface 21 is bigger with the intensity of pressure that gasket seal or other junction surface receive, make that sealing effect between the two is better.
In order further to optimize technique scheme; In the above-mentioned flange; Can wherein strengthen the intersection that the space can be arranged on flanged surface 21 and madial wall with strengthening the intersection that the space is arranged on flanged surface 21 with the sidewall of flange, also can be arranged on the intersection of flanged surface 21 and outer side wall; Can also be through removing the part materials to form the reinforcement space with the positions that flanged surface 21 intersects at the madial wall of flange or outer side wall; Certainly can also pass through other modes,, equally also can reach the purpose that the area that makes flanged surface 21 reduces such as on flanged surface 21, groove being set.
Wherein, identical in order to guarantee this flange with the caliber that other pipeline connects formed pipeline, can be with strengthening the intersection that the space is arranged on flanged surface 21 with the outer side wall of flange; Wherein flanged surface 21 is connected through median surface with outer side wall; Promptly remove the part material with the intersection of outer side wall and form median surface at flanged surface 21, wherein, for more convenient to operate; Can be set to sphenoid surface 22 by median surface; Directly like this get final product, can certainly be concave surface or convex surface, do not do qualification at this with Tool in Cutting.
In order further to optimize technique scheme, better in the above-mentioned flange in order to make sealing effect, also can around flanged surface 21, all be provided with and strengthen the space, so also make the stressed more even of flanged surface 21.If this flange is connected with the higher device of other temperature, such as being connected with gas exhaust manifold, the temperature of the bolt that then both is connected also can increase; Cause the thermal stress of bolt to increase; Therefore bolt is more fragile, so for bolt is dispelled the heat more easily, can bolt hole that strengthen space and flange 23 be intersected; The part of bolt contacts with strengthening the space like this, and radiating effect is more obvious.
Based on the flange that provides in the foregoing description, the utility model also provides a kind of gas exhaust manifold structure, comprises gas exhaust manifold 1 and the flange 2 that is arranged on the pipe end of gas exhaust manifold, and wherein flange 2 is above-mentioned any one flange.Because this gas exhaust manifold structure has adopted the flange in the foregoing description, so the beneficial effect of this gas exhaust manifold structure please refer to the foregoing description.
Wherein, in order to increase the intensity of above-mentioned gas exhaust manifold structure, can be integral structure with gas exhaust manifold 1 with flange 2, processing technology is simpler simultaneously.
