Abstract
The utility model discloses an air inlet valve piston structure, which comprises a valve plate assembly, a piston and a cylinder sleeve. A valve disc is correspondingly arranged on the air inlet hole and the air exhaust hole of the valve plate. The air inlet valve piston structure is characterized in that a groove is arranged on a piston head, a part made of elastic materials is arranged in the groove and the position of the groove at the piston head corresponds to the position of the valve disc from top to bottom. The utility model has the advantages that the structure is simple, the installation is convenient, the damping and muffling function is obtained and thereby the service life of the valve disc is prolonged.
Description
Technical field
The utility model relates to the air compressor technical field, relates to the valve piston structure on a kind of air compressor more specifically.
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 beats on the piston head pressing plate, not only can make a noise, and shorten the working life of valve block.
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 has the air intake valve piston structure of buffering sound deadening.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of air intake valve piston structure, comprise valve board assembly, piston and cylinder liner, correspondence is provided with valve block on the inlet and outlet hole of valve plate, it is characterized in that, have groove on the piston head, be provided with elastomeric parts in the groove, the groove location of piston crown is corresponding up and down with the valve block position.
As further specifying of such scheme, described groove is arranged on the piston head end face, and the degree of depth of groove is greater than the thickness of valve block.
Described elastomeric parts is a sheet, is fixed in the groove by bonding mode.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts sets up the elastomeric parts corresponding with valve block at the end face of piston head, and in air inlet moment, air-intake valve plate is opened, and beats on the elastic material on the pressing plate, plays the buffering sound deadening, has also prolonged the working life of valve block thus.

Description of reference numerals: 1, valve board assembly 2, piston 3, cylinder liner 4, valve block 5, groove 6, elastomeric parts
Embodiment
As Fig. 1～shown in Figure 3, a kind of air intake valve piston structure of the utility model comprises valve board assembly 1, piston 2 and cylinder liner 3, correspondence is provided with valve block 4 on the inlet and outlet hole of valve plate, have two grooves 5 on the piston head end face, be provided with elastomeric parts 6 in the groove 5, generally select rubber for use.The groove location of piston crown is corresponding up and down with valve block 4 positions, and the degree of depth of groove 5 is greater than the thickness of valve block 4.Elastomeric parts 6 is a sheet, is fixed in the groove 5 by bonding mode.
In the using process, in air inlet moment, air-intake valve plate is opened, and beats on the elastic material on the pressing plate, plays the buffering sound deadening.
Above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that.Still can make amendment or the part technical characteristics is equal to replacement the embodiment of model utility; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
