Abstract
The invention discloses a sound reduction structure of an air inlet piston. The sound reduction structure comprises a connecting rod and a valve plate assembly arranged on the end part of the connecting rod; the valve plate assembly is provided with a press plate and a picking leather; a valve is arranged on the press plate; and the sound reduction structure is characterized in that a sound reduction filter is arranged on an air inlet hole of the valve, the sound reduction filter mainly comprises a sound reduction tube and sound reduction cotton arranged in the sound reduction tube, and the top part of the sound reduction tube is provided with a sound reduction cover. The sound reduction structure is simple and convenient in installation, has favorable promotion valves, and plays a role in sucking air and reducing sound.
Description
Technical field
The present invention relates to the compressor apparatus technical field, specifically a kind of air inlet piston structure of compressor.
Background technique
At present, compresser cylinder on the market mainly is made of cylinder sleeve, cylinder cap and inner valve plate, valve block thereof, valve plate is fixed on the cylinder liner top, makes by the mode of die casting, and cylinder liner then needs stretched technology to make, the joint of cylinder sleeve and valve plate is provided with the seal ring sealing, valve plate is provided with port and valve block, and valve block all is a slabbing, and valve plate and valve block are fastening with screw, structure is comparatively simple, therefore extensive use in existing compressor.But in air inlet moment, air-intake valve plate is opened, and gas can make a noise through inlet hole, and the user is brought adverse effect.
Summary of the invention
Purpose of the present invention is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy for installation, and has the air inlet piston noise-reducing structure of sound deadening.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of air inlet piston noise-reducing structure, the valve board assembly that comprises connecting rod and be arranged on interlinking lever end, be provided with pressing plate and leather cup in the valve board assembly, pressing plate is provided with valve, it is characterized in that, the noise reduction filter is housed on the inlet hole of described valve, and the noise reduction filter mainly is made of the noise reduction cotton of hush pipe and interior setting thereof, and the top of hush pipe is equipped with the noise reduction lid.
As further specifying of such scheme, the end of described connecting rod is provided with and the concavo-convex pedestal that cooperates of pressing plate, and the outer rim of pedestal is provided with step, and leather cup is fixed in pedestal outer rim ledge surface by pressing plate.
The sealing valve block is housed on the described inlet hole, the sealing valve block by a pad and screw in the pressing plate end.
Described hush pipe top edge stretches out, and the end face of pedestal is provided with the groove that cooperates with hush pipe and top noise reduction lid thereof, and the bottom of groove is provided with through hole, and through hole and outstanding on pedestal is passed in the bottom of hush pipe.
Be provided with the O RunddichtringO between described hush pipe and the pedestal, pressing plate presses noise reduction lid, O RunddichtringO in the groove of pedestal end face.
Described hush pipe both sides are provided with inlet hole, and noise reduction covers and is distributed with plural air outlet hole.
Be connected with the suction tude joint on the described inlet hole.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention is provided with the main noise reduction filter that is made of the noise reduction cotton of hush pipe and interior setting thereof on the valve plate inlet hole of piston, air enters from the hush pipe both sides, through entering into valve board assembly from a plurality of air outlet holes respectively after the cotton filtration of noise reduction, can absorb the noise more than 95%, reach the effect of air inlet noise reduction.
