Abstract
The utility model discloses a valve chamber cover gasket structure with good stability performance. The valve chamber cover gasket structure is characterized by comprising a long-frame-shaped gasket body made of paperboard materials, the upper end face and the lower end face of the gasket body are respectively coated with a black butyronitrile rubber layer with the thickness ranging from 0.04mm to 0.09mm, installing holes and strip-shaped positioning holes are distributed in one side of the long-frame-shaped gasket body, an installing hole, a fan-shaped positioning hole and a semi-circular positioning boss protruding outwards are distributed in the other side of the gasket body, one end of the gasket body is provided with an arc-shaped positioning protrusion, and the other end of the gasket body is provided with an arc-shaped positioning groove. The sealing performance of the gasket body is enhanced through the black butyronitrile rubber layer structures coating a paperboard, and due to the structural design of the strip-shaped positioning holes, the fan-shaped positioning hole, the semi-circular positioning boss all of which are formed in the two sides and the arc-shaped positioning protrusion and the arc-shaped positioning groove both of which are formed in the end, the valve chamber cover gasket structure is convenient to install and fix, good in stability performance and not prone to being moved and guarantees the sealing performance.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to the valve-chamber cover gasket construction that a kind of stability is good.
Background technique
The effect of valve-chamber cover packing ring is that auxiliary valve chamber cap pad is used for preventing leakage of oil and foul, water enters cylinder head, existing gasket construction is simple, is mostly the frame-shaped construction that adopts paper board material directly to make, and is provided with mounting hole and positioning hole, it is simple in structure, poor sealing performance is installed fixing inconvenience, poor stability simultaneously, easily mobile, affect its sealability.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and the valve-chamber cover gasket construction that a kind of stability is good is provided.
The utility model is achieved through the following technical solutions:
The valve-chamber cover gasket construction that a kind of stability is good, it is characterized in that: the packing ring body that includes long frame shape, described shim body adopts paper board material to make, on its upper and lower end face, be coated with respectively black butyronitrile glue-line, the thickness of described black butyronitrile glue-line is 0.04-0.09mm, one side of described long frame shape packing ring body is distributed with mounting hole and bar shaped positioning hole, the opposite side of described packing ring body is distributed with mounting hole, fan-shaped positioning hole and outwardly semicircle positioning boss, one end of described packing ring body is provided with arc positioning convex, the other end is provided with arc positioning groove.
The utility model has the advantages that:
The utility model is by the structure of the black butyronitrile glue-line that applies on cardboard, increased the sealability of packing ring body, simultaneously by the arc positioning convex of bar shaped positioning hole, fan-shaped positioning hole, semicircle positioning boss and end and the structural design of arc positioning groove of both sides, it installs convenient fixing, stability is good, be not easy to move, guaranteed sealability.
