Abstract
The invention discloses an air cylinder component of a piston compressor. The air cylinder component comprises a cylinder body, a piston carrying out reciprocating movement along the inner cavity of the cylinder body, a valve block sealing and covering the end portion of the inner cavity of the cylinder body and a gasket arranged between the cylinder body and the valve block in a sealing mode. A concave portion is arranged on the end portion, close to the valve block, of the piston, the center of the concave portion is the lowest concave point, and the concave depth of the lowest concave point is smaller than or equal to 0.015mm. Under the limitation of the constant-value distance between the center of the upper end portion of the piston and the valve block, the concave portion is arranged on the upper end face of the piston, when the piston is located on the uppermost portion inside the cylinder body, exhaust residue space formed among the cylinder body, the piston, the gasket and the valve block is effectively reduced, the total amount of the exhaust gas of the piston within a movement period is increased, and the performance and the working efficiency of the compressor are effectively improved.
Description
Technical field
The present invention relates to a kind of cylinder assembly of piston compressor.
Background technique
Piston compressor is generally adopted in refrigeration system, its working efficiency directly affects the work of whole refrigeration system, and the principal element that determines the working efficiency of piston compressor is cylinder assembly, cylinder assembly in conventional art (as shown in Figure 1), the end of the close valve block 4 ' of piston 2 ' wherein is rule or irregular convex, when piston 2 ' is positioned at the topmost part in cylinder body 1 ', cylinder body 1 ', piston 2 ', form the remaining space of exhaust between liner 3 ' and valve block 4 ', restriction due to the convex of the center of piston 2 ' upper end portion and the distance of the definite value between valve block 4 ' and piston 2 ' upper end portion, cause the remaining space of this exhaust larger, there is more residual gas not discharge, just cause the exhaust total amount of piston 2 ' within a cycle of motion to reduce, affect performance and the working efficiency of compressor.
Summary of the invention
For the technical deficiency of above-mentioned existence, the purpose of this invention is to provide a kind of cylinder assembly of piston compressor, it dwindles the remaining space of exhaust to improve performance and the working efficiency of compressor.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of cylinder assembly of piston compressor, comprise cylinder body, along the reciprocating piston of the inner chamber of described cylinder body, valve block, the sealing of end that be sealed on the inner chamber of described cylinder body, be arranged on the liner between described cylinder body and described valve block, the end of the close described valve block of described piston has recess and center is the depression minimum point, and the cup depth of described depression minimum point is less than or equal to 0.015mm.
Preferably, described recess is the sphere depression.
Preferably, described recess is the frustum depression.
Preferably, when described piston is positioned at the topmost part in described cylinder body, the minimum perpendicular distance between the upper-end surface of described depression minimum point and described cylinder body is much larger than 0.015mm.
Beneficial effect of the present invention is: under the restriction of definite value distance between the center of the upper end portion of piston and valve block, upper-end surface at piston arranges recess, while making piston be positioned at the topmost part in cylinder body, effectively dwindled the remaining space of the exhaust formed between cylinder body, piston, liner and valve block, just make the total amount of the gas that piston discharges within a cycle of motion increase, effectively improved performance and the working efficiency of compressor.
The accompanying drawing explanation
Accompanying drawing 1 is the structural representation (analysing and observe) of the cylinder assembly of the piston compressor in conventional art;
The structural representation (analysing and observe) of the cylinder assembly that accompanying drawing 2 is piston compressor of the present invention.
In accompanying drawing: 1, cylinder body; 2, piston; 3, liner; 4, valve block.
Embodiment
Below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
Above-below direction in this specification is identical with illustrated above-below direction in accompanying drawing 1 and accompanying drawing 2.
As shown in Figure 2, a kind of cylinder assembly of piston 2 compressors, comprise cylinder body 1, along the reciprocating piston 2 of the inner chamber of cylinder body 1, be sealed on the valve block 4 of end of the inner chamber of cylinder body 1, sealing is arranged on the liner 3 between cylinder body 1 and valve block 4, the end of the close valve block 4 of piston 2 has recess and center is the depression minimum point, for guaranteeing between piston 2 centers, upper end portion and valve block 4 apart from and guaranteeing that the peak of upper end portion does not touch valve block 4, the cup depth of depression minimum point is less than or equal to 0.015mm, the depression that preferably above-mentioned recess is sphere, can certainly make the frustum depressions such as circular cone depression or the frustum of a pyramid, and, when piston 2 is positioned at the topmost part in cylinder body 1, minimum perpendicular distance between the upper-end surface of depression minimum point and cylinder body 1 is much larger than 0.015mm.
Above-mentioned, when piston 2 is positioned at the topmost part in cylinder body 1, form the remaining space of exhaust between cylinder body 1, piston 2, liner 3 and valve block 4, recess arrangement due to the design's piston 2 upper end portions, in the situation that require piston 2 centers, upper end portion identical with the perpendicular distance between valve block 4, the remaining space of the design's exhaust is less than in original technology, just makes the total amount of the gas that piston 2 discharges within a cycle of motion increase, and has effectively improved performance and the working efficiency of compressor.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that spirit is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
