Abstract
The utility model discloses a compressor air intake silencer which is characterized in that the compressor air intake silencer and a compressor cylinder cover are an integrated structure which mainly comprises a labyrinth type airway arranged in the compressor cylinder cover and a cavity connected therewith, and the cavity is connected with a valve sheet of an air inlet chamber of a compressor cylinder through a round hole pipeline. The compressor air intake silencer achieves the physical silencing effect through the volume change of air from amplification and reduction to further amplification and reduction and has the advantages of simple structure, low production cost, good silencing effect and no need of additional installation, thereby having good popularization value.
Description
Technical field
The utility model relates to the Compressor Technology field, more particularly relates to a kind of air inlet noise-reducing structure of compressor.
Background technique
Traditional compressor air inlet noise-reducing structure is to adopt cotton medium of noise reduction or external sound-muffling box to carry out noise reduction, it is an absolute construction, be connected with cylinder, traditional cylinder head intake and exhaust chamber all is a common volume cavity volume, as Chinese patent application number is 98121335, the applying date is on October 9th, 1998, denomination of invention is the air suction silencer of compressor, it is characterized in that, comprise: main body, have the expansion chamber that makes the gaseous refrigerant expansion that is flowed into by vaporizer, the resonant chamber of resonance takes place in refrigerant therein that be used to extract the suction chamber of the refrigerant that expands at described expansion chamber and make the described suction chamber of suction; And suction pipe, being assembled together with described main body and described suction chamber and cylinder of compressor lid are interconnected, described suction pipe flows into the passage that described cylinder head provides for the refrigerant in the described suction chamber.The refrigerant of this patent resonance in resonant chamber can reduce the noise of characteristic frequency, and is simple in structure, and the quantity of part is few.Its shortcoming is a baffler manufacture cost height, need connect cylinder head with pipeline, installs inconvenient.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy for installation, and the compressor intake silencer of good muffling effect.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of compressor intake silencer, it is characterized in that: it and compressor cylinder cover are an overall structure, mainly be made of inner mazy type air flue and the connected cavity volume that is provided with of compressor cylinder cover, cavity volume connects the air-inlet cavity valve block of compresser cylinder by the circular hole pipeline.
As further specifying of such scheme, cylinder head inside is divided into two cavity volumes and an air flue, and air flue is connected between two cavity volumes.
The middle part of described cylinder head is provided with vertically and the dividing plate of transverse distribution, and the end of dividing plate and the joint of cylinder head also are provided with opening.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model adopts compressor cylinder cover inside that mazy type air flue and connected cavity volume are set, it is the path that is used for changing gas by stopping up earlier, by mazy structure gas is entered the another one cavity volume by big cavity volume through narrow air flue again, enter the air-inlet cavity valve block by the circular hole pipeline then.This structure is reached the effect of physics noise reduction by making gas by the volume-variation of amplifying, dwindling and then amplifying, dwindling.
