Model utility content
The purpose of this utility model is to provide Air Compressors Valve Plates noise reduction and position structure, and the position of the corresponding air-intake valve plate of pressing plate arranges rubber pad, and such air-intake valve plate operationally only collides with rubber cushion, thus plays the effect of noise reduction; The utility model also arranges spacing boss in valve block both sides in addition, positioning action is played when valve block is installed, position-limiting action is played during work, improve installation efficiency and installation precision, and screw slightly loosen time, valve block can not rotate, and effectively prevents because screw slightly loosens the air compressor lost of life caused.
For achieving the above object by the following technical solutions:
A kind of Air Compressors Valve Plates noise reduction and position structure, comprise cylinder, connecting rod, piston, valve plate and cylinder cap, described piston comprises piston cup and pressing plate, piston cup and pressing plate are fixed by screws in connecting rod top, piston cup is clamped in centre by pressing plate and connecting rod top, described valve plate drives into pore and exhaust port, inlet hole and exhaust port place are respectively arranged with air-intake valve plate and exhaust valve plate, air-intake valve plate is fixed on valve plate by screw and pad, exhaust valve plate is fixed on valve plate by valve block limiting stopper and screw, it is characterized in that: on the position of the corresponding air-intake valve plate of described pressing plate, be provided with rubber pad, the end face of a little higher than pressing plate in top of rubber pad, contact with rubber pad during air-intake valve plate work.
A through hole is had in the position of air-intake valve plate corresponding to described pressing plate, the little middle forming station stage structure in aperture, large top, aperture, through hole bottom, described rubber pad arranges the convex rubber pad mated with shape of through holes, the extruding at convex rubber pad lower compression plate and connecting rod top is fastened between pressing plate and connecting rod, convex rubber pad top is passed through hole and is made a little higher than pressing plate end face of convex rubber pad end face, and ensures that air-intake valve plate work does not contact with pressing plate end face.
The limiting stopper of described exhaust valve plate increases the end face of two boss or corresponding size, valve plate increases the groove or boss that are mated, when exhaust valve plate limiting stopper and valve plate are installed on valve plate, boss and groove fit there has also been positioning limit in exhaust valve plate both sides simultaneously; Increase by two positioning boss or groove near valve plate inlet hole, pad has end face or the boss of the corresponding size be mated, air-intake valve plate is arranged between two positive stop lug boss and plays positioning action.
The utility model arranges rubber pad on the position of the corresponding air-intake valve plate of pressing plate, and the end face of a little higher than pressing plate 4 in the top of rubber pad, such air-intake valve plate 10 operationally only collides with rubber cushion, thus plays the effect of noise reduction; The utility model is provided with boss at air-intake valve plate and exhaust valve plate both sides simultaneously, positioning action is played in the both sides of valve block, so both improve installation efficiency and installation precision, simultaneously when screw slightly loosens, valve block can not rotate, and effectively prevents because screw slightly loosens the problem of the air compressor lost of life caused.
