Abstract
The utility model discloses an air inlet valve piston structure of a compressor; the air inlet valve piston structure comprises a valve plate component, a piston and an air cylinder jacket; a valve sheet is arranged on an air inlet hole of the valve plate component; the air inlet valve piston structure is characterized in that a slant groove is arranged on the head of the piston; and the slant groove corresponds to the valve sheet on the air inlet hole of the valve plate component up and down in position. The air inlet valve piston structure has the functions of buffering and noise reduction, thereby prolonging the service life of the valve sheet; and the air inlet valve piston structure has a simple structure, is convenient to install and has good popularization value.
Description
Technical field
The utility model relates to the Compressor Technology field, a kind of specifically compressor air intake valve piston structure.
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 at intake process, air-intake valve plate is opened, and pats piston end surface, 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 accessibility, and have the compressor air intake valve piston structure of buffer protection valve block effect.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of compressor air intake valve piston structure, comprise valve board assembly, piston and cylinder liner, the inlet hole of valve board assembly is provided with valve block, it is characterized in that, have inclined plane groove on the described piston crown, the inclined plane groove position is corresponding up and down with the inlet hole valve block position of valve board assembly.
As further specifying of such scheme, described valve block is fixed in by fastening piece on the inlet hole of valve plate, and this fastening piece comprises screw and pad.
Described inclined plane groove is camber, and the inclined-plane links to each other with piston end surface.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts piston crown that inclined plane groove is set, its position is corresponding up and down with the inlet hole valve block position of valve board assembly, shape is close, in air inlet moment, air-intake valve plate is opened, beat on the groove inclined-plane on the pressing plate, the buffering sound deadening is played in the face contact, has also prolonged the working life of valve block thus.

Fig. 2 is a compressor arrangement schematic representation of the present utility model;
Fig. 3 is a piston structure schematic representation of the present utility model.
Description of reference numerals: 1, valve board assembly 2, piston 3, cylinder liner 4, cylinder cap 5, valve block 6, inclined plane groove
Embodiment
As Fig. 1～shown in Figure 3, a kind of compressor air intake valve of the utility model piston structure comprises valve board assembly 1, piston 2 and cylinder liner 3, and the top of cylinder liner 3 is provided with cylinder cap 4, there is interlayer between cylinder cap 4 inside and outside walls, this cylinder cap interlayer vacuum or sound insulation by filling material.The inlet hole of valve board assembly 1 is provided with valve block 5, and valve block 5 is fixed in by fastening piece on the inlet hole of valve plate, and this fastening piece comprises screw and pad.Have inclined plane groove 6 on the piston crown, inclined plane groove 6 is camber, and the inclined-plane links to each other with piston end surface, and the inclined plane groove position is corresponding up and down with the inlet hole valve block position of valve board assembly.
In the using process, in air inlet moment, air-intake valve plate is opened, and beats on the groove inclined-plane on the pressing plate, and the buffering sound deadening is played in the face contact, has also prolonged the working life of valve block thus.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (3)
