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 compressor apparatus technical field, specifically a kind of inlet piston structure of compressor.
Background technique
At present, compresser cylinder on market is formed primarily of the valve plate of cylinder sleeve, cylinder cap and inside thereof, valve block, valve plate is fixed on cylinder liner top, is made by the mode of die casting, and cylinder liner then needs stretched technique to obtain, the joint of cylinder sleeve and valve plate arranges seal ring sealing, valve plate is provided with port and valve block, valve block is all slabbing, and valve plate and valve block are with screw fastening, 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, brings adverse effect to user.
Summary of the invention
Object of the present invention be exactly deficiency in order to solve prior art and the one provided not only structure is simple, easy for installation, and there is the sound reduction structure of air inlet piston of sound deadening.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of sound reduction structure of air inlet piston, comprise connecting rod and be arranged on the valve board assembly of interlinking lever end, pressing plate and leather cup is provided with in valve board assembly, pressing plate is provided with valve, it is characterized in that, the inlet hole of described valve is equipped with silencing filter, and silencing filter is formed primarily of the silencing cotton of hush pipe and interior setting thereof, and the top of hush pipe is provided with noise reduction lid.
Further illustrating as such scheme, the end of described connecting rod is provided with the pedestal with pressing plate male-female engagement, and the outer rim of pedestal is provided with step, and leather cup is fixed on pedestal outer rim ledge surface by pressing plate.
Described inlet hole is equipped with sealing valve block, sealing valve block is fixed on pressing plate end by a pad and screw.
Described hush pipe top edge stretches out, and the end face of pedestal is provided with the groove coordinated with hush pipe and top noise reduction lid thereof, and the bottom of groove is provided with through hole, and the bottom of hush pipe is also outstanding on pedestal through through hole.
Be provided with O RunddichtringO between described hush pipe and pedestal, noise reduction lid, O RunddichtringO press in the groove of base end face by pressing plate.
Described hush pipe both sides are provided with inlet hole, and noise reduction covers and is distributed with plural air outlet hole.
Described inlet hole is connected with suction tude joint.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention arranges the silencing filter that the silencing cotton primarily of hush pipe and interior setting thereof is formed on the valve plate inlet hole of piston, air enters from hush pipe both sides, valve board assembly is entered into from multiple air outlet hole respectively after silencing cotton filters, the noise of more than 95% can be absorbed, reach the effect of air inlet noise reduction.
