Abstract
The utility model discloses an intake pipe pad of face pressure equipartition relates to the intake pipe pad field of face pressure equipartition, including filling up body, inlet port, bolt hole, location mounting hole. The cushion body is made of a single-layer hard stainless steel plate, and inclined sealing ribs with different widths and heights are pressed at the periphery of the air inlet according to different positions so as to obtain the uniformity of the sealing surface pressure and prevent the leakage of air inlet at a low surface pressure position. The utility model has the advantages that: the utility model discloses compare with other air inlet pipe cushions, the peripheral sealed face of inlet port presses more evenly unanimously, can not produce the seepage phenomenon, and long service life is favorable to encircleing the protection, has greatly improved the reliability and the durability of engine.
Description
Technical Field
The utility model relates to a field of engine intake pipe, concretely relates to intake pipe pad of face pressure equipartition.
Background
The air inlet pipe gasket is one of important sealing gaskets of the engine, and ensures that air entering each combustion chamber is uniform and consistent, and the vibration phenomena of gas explosion, uneven power and uneven sound of explosion of each cylinder caused by uneven air inlet due to air inlet leakage are avoided. The sealing ribs on the periphery of the past air inlet pipe gasket are uniform, so that the phenomena of uneven sealing surface pressure and air outlet leakage at a low pressure part are frequently generated, and the performance of an engine is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide an intake pipe pad of face pressure equipartition, it is good to have sealing technique, long service life, the advantage that does benefit to the environmental protection.
The purpose of the utility model is accomplished through following technical scheme: the air inlet pipe gasket with uniformly distributed surface pressure comprises a gasket body, wherein an air inlet hole, a bolt hole and a positioning installation hole are formed in the gasket body, an inclined sealing rib is arranged on the periphery of the air inlet hole, the width of the inclined sealing rib is gradually reduced from the position close to the bolt hole to the position far away from the bolt hole, the height of the inclined sealing rib is gradually increased from the position close to the bolt hole to the position far away from the bolt hole, and the sealing force of each part on the inclined sealing rib is kept consistent.
As a preferable technical scheme, the inclined sealing ribs with different widths are connected by adopting smooth transition or tangent lines.
As a preferable technical scheme, the cushion body is made of a single-layer stainless steel hard plate.
The beneficial effects of the utility model are that: compared with the prior art, the structure is more reasonable, the performance is more reliable, the sealing effect is better, the practical service life is longer, the surrounding protection is facilitated, and the reliability and the durability of the engine are greatly improved.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing 1, the air inlet pipe gasket with uniformly distributed surface pressure comprises a gasket body 1, wherein an air inlet hole 2, a bolt hole 3 and a positioning installation hole 4 are arranged on the gasket body 1, an inclined sealing rib is arranged at the periphery of the air inlet hole 2, the width of the inclined sealing rib is gradually reduced from a position close to the bolt hole 3 to a position far away from the bolt hole 3, the height of the inclined sealing rib is gradually increased from a position close to the bolt hole 3 to a position far away from the bolt hole 3, and the sealing force of each position on the inclined sealing rib is kept consistent. Preferably, the cushion body 1 is made of a single layer of stainless steel hard plate.
Further, the inclined sealing ribs with different widths are connected by adopting smooth transition or tangent lines. Referring to fig. 2 and 3, the height of the inclined sealing rib is varied and the width of the cross section is varied, in the cross-sectional viewsbase:Sub>A-base:Sub>A, H-H and G-G, the widthbase:Sub>A 2 of the inclined sealing rib is 2.5mm and the heightbase:Sub>A 1 is 0.45 ± 0.1mm, in the cross-sectional views B-B and F-F, the width B2 of the inclined sealing rib is 2.0mm and the height B1 is 0.55 ± 0.1mm, in the cross-sectional view C-C, the width C2 of the inclined sealing rib is 1.5mm and the height C1 is 0.6 ± 0.1mm, and in the cross-sectional views D-D and E-E, the width D2 of the inclined sealing rib is 1.0mm and the height D1 is 0.65 ± 0.1mm.
The utility model discloses the sealed muscle width and the height that set up in each cross-section department of intake pipe are the assorted, and the width reduces to keeping away from bolt hole department from being close to bolt hole department gradually, highly follow from being close to bolt hole department to keeping away from bolt hole department crescent to guarantee that the sealed power of everywhere on the sealed muscle of slope shape is approximate unanimous.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
