Abstract
The utility model relates to a valve core of a needle valve for an automotive carburetor, which is composed of a valve core head and a valve core body. The upper portion of the valve core head is a cone with 60 DEG to 75 DEG, and the lower portion of the valve core head is a cylinder. The valve core body is a prism body, and a small cylindrical hole is arranged in the upper portion of the valve core body The cylinder of the lower portion of the valve core head is inserted into the small cylindrical hole of the upper portion of the valve core body, and is fixed by adhesive. Since the valve core head adopts oil-resistant rubber which has flexibility, the matching and sealing performance of the valve core head with a copper outer jacket is improved. The utility model efficiently solves the problem that an automobile carburetor is choked by oil, and the service life can be improved by 6 to 7 times. The utility model has simple structure, money saving and high durability.
Description
The utility model is a kind of automobile carburetor needle-valve spool.
Existing automobile carburetor needle-valve spool system adopts stainless steel material to make an integral body, because it is relatively poor with the fitted seal of copper overcoat, institute is so that have automobile ubiquity " fuel fouling " problem now.
The purpose of this utility model is to provide a kind of spool is made valve core head and valve core two parts, plug together then and be integral, valve core head adopts oil resistant rubber to make, and has ductility, therefore good seal performance, and can effectively solve the automobile carburetor needle-valve spool of automobile carburetor " fuel fouling " problem.
The purpose of this utility model is realized by following technological scheme: it is made up of valve core head (1) and valve core (2), and valve core head (1) top is 60 °～75 ° cone, and its underpart is a cylindrical body; Valve core (2) is a prism, has a small cylindrical opening, bottom that one big column hole (21) is arranged in its top, one air hole (22) is arranged between two holes, the cylindrical body of valve core head (1) bottom inserts in the small cylindrical opening on valve core (2) top, and drive fit is affixed with tackiness agent.Valve core head (1) adopts oil resistant rubber to make, as: fluorine rubber, silicone rubber or fourth-cyanogen rubber; Valve core can be tri-prismoid, and four prisms cylinder or multiedge cylinder adopt metallic material to make, as copper, aluminium etc.; Tackiness agent is a Kai Muluoke glue.
The utility model has the advantages that: because valve core head adopts oil resistant rubber, has ductility, therefore the fitted seal performance with the copper overcoat increases substantially, solved automobile carburetor " fuel fouling " problem effectively, can improve 5～6 times working life, original stainless steel spool uses about three months i.e. appearance " fuel fouling " phenomenons, and the utility model can use about a year and a half.The utility model is simple in structure, and economy and durability is applied widely, can be used in the various automobile carburetors.
In conjunction with the accompanying drawings and embodiments the utility model is described further:
Fig. 1 is an automobile carburetor needle-valve valve core structure schematic representation
Fig. 2 is an automobile carburetor needle-valve spool worm's eye view
In the described automobile carburetor needle-valve of embodiment spool, the oil resistant rubber that valve core head (1) adopts is a fluorine rubber, and its top is 70 ° cone, and circular cone bottom surface diameter is 7 millimeters, and its underpart is the cylindrical body of 4.5 millimeters of diameters; Valve core (2) is a four prisms cylinder, seamed edge is 8 millimeters, the employing copper material is made, the small cylindrical opening that 4.5 millimeters of one diameters are arranged in its top, the big column hole of 6.5 millimeters of one diameters is arranged at the bottom, 0.5 millimeter air hole of one diameter is arranged between two holes, and the cylindrical body of valve core head (1) bottom inserts in the small cylindrical opening on valve core (2) top, and is affixed with Kai Muluoke glue.
