Abstract
The utility model discloses a sealing pressure-maintaining structure for a piston head of a compressor. The sealing pressure-maintaining structure comprises a connecting rod, a leather cup, screws and a pressing plate. The leather cup is fixed on the end face of the connecting rod through the screws and the pressing plate. The sealing pressure-maintaining structure is characterized in that a sealing ring is arranged between the pressing plate and the connecting rod. With the adoption of the sealing pressure-maintaining structure, a piston work cavity is separated from a hollow cavity positioned between the pressing plate and the connecting rod so as not to leak, so that the work pressure and the flux are guaranteed; in addition, the sealing pressure-maintaining structure for the piston head of the compressor has the advantages of simple structure, convenience in installation and good popularization value.
Description
Technical field
The utility model relates to the Compressor Technology field, relates to a kind of piston head sealing pressurize structure of compressor in particular.
Background technique
Air compressor through blade or rotor rotatablely move or the to-and-fro motion of piston with air compression in gas tank, and exhaust when needed.At present, the piston assembly of compressor on the market mainly is made up of connecting rod, leather cup, pressing plate and screw, and leather cup is through pressing plate and the screw end face at connecting rod; End face at connecting rod is provided with cavity, owing between screw, leather cup and the pressing plate sealing configuration is not set, because; Piston assembly is in running; Be easy to generate leakage, be difficult to guarantee the working pressure and the flow of compressor, influence the global stability of compressor.
The model utility content
The purpose of the utility model is exactly provide for the deficiency that solves existing technology a kind of not only simple in structure, easy for installation, and can guarantee the compressor piston head sealing pressurize structure of compressor operating pressure and flow.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of compressor piston head sealing pressurize structure; Comprise connecting rod, leather cup, screw and pressing plate; Leather cup is fixed in the end face of connecting rod through screw and pressing plate; It is characterized in that, be provided with seal ring between said pressing plate and the connecting rod.
As further specifying of such scheme: the middle part of said connecting rod end face is provided with the screw corresponding with said screw, and screw is outside equipped with circular groove, and seal ring is arranged in the circular groove.
The axis coinciding of said screw and circular groove.
The circular groove of said connecting rod end face is outside equipped with the annular chamber with its concentric, and the outer rim of annular chamber is provided with the locating column that cooperates with leather cup inner ring roof pressure.
The quantity of said locating column is more than three.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model is employed between piston pressing plate and the connecting rod and places seal ring; After on the connecting rod, the certain deformation amount is arranged through seal ring and screw lock pressing plate, leather cup; Cavity between pistons work chamber and pressing plate, the connecting rod is separated, be unlikely to leak, guarantee working pressure and flow.
