Abstract
The invention discloses a kind of Reciprocting piston compressor valve seat end face structures, including valve plate body, valve plate body is equipped with inspiration valve seat end face and delivery valve seat end face, and the inward flange of inspiration valve seat end face and delivery valve seat end face is respectively equipped with chamfering structure, which can be fillet or oblique angle.The present invention has taken into account the reliability of compressor valve plate well, has flopped the Energy Efficiency Ratio of noise and compressor, it efficiently reduces suction valve chip and exhaust valve plate flops the deformation generated when respective valve seat end face and panting stress, facilitate the reliability of promotion suction and discharge valve block, and reduces slap noise.Simultaneously as chamfering structure has certain flow conductivity, thus it can also promote compressor refrigerating capacity, to promote complete machine Energy Efficiency Ratio.
Description
Technical field
The present invention relates to Reciprocting piston compressor technical field, specifically a kind of reciprocating-piston that is applied to compresses
The valve seat end face structure of machine.
Background technique
The inspiration valve seat end face and delivery valve seat end face of valve plate influence the reliability of suction and discharge valve block.On the one hand, work as valve
When piece flops downwards valve seat end face, suitable valve seat end face width is conducive to reduce the slap energy on unit area, and improvement connects
Touch the deformation and stress distribution of original state lower disc；On the other hand, with the progress of slap process, valve block and valve seat end face by
Face contact switchs to line contact.Since the inward flange design of existing valve seat end face is more sharp, contact area is smaller, leads to valve block more
Big deformation and by bigger stress, thus compressor be in long-play under operating condition or laboratory lifetimes operating condition with
Afterwards, it will form apparent line contact slap trace on valve block, finally make valve block broken, influence the reliability of compressor.In addition,
How to promote compressor complete machine Energy Efficiency Ratio under the premise of guaranteeing compressor reliability is an industry problems, and existing valve seat end
The inward flange design in face is more sharp, and flow conductivity is insufficient, can not effectively promote compressor refrigerating capacity, limit compressor complete machine
The promotion of Energy Efficiency Ratio.
Summary of the invention
Technical problem to be solved by the present invention lies in propose it is a kind of can preferably take into account the suction of compressor, exhaust valve plate can
By property, the Reciprocting piston compressor valve seat end face structure of slap noise and compressor complete machine Energy Efficiency Ratio.
In order to solve the above technical problems, a kind of Reciprocting piston compressor valve seat end face structure of the present invention includes valve plate sheet
Body, the valve plate body are equipped with inspiration valve seat end face and delivery valve seat end face, the inspiration valve seat end face and delivery valve seat end
The inward flange in face is respectively equipped with chamfering structure.
A kind of above-mentioned Reciprocting piston compressor valve seat end face structure, the inspiration valve seat end face and delivery valve seat end face
The chamfering structure of inward flange be fillet, the radius of corner of inspiration valve seat end face inward flange and the inspiration valve seat end face
The ratio point of the width of the radius of corner of the ratio of width and delivery valve seat end face inward flange and the delivery valve seat end face
It Wei 0.2~0.4.
A kind of above-mentioned Reciprocting piston compressor valve seat end face structure, the inspiration valve seat end face and delivery valve seat end face
Inward flange chamfering structure be oblique angle, the angle at oblique angle is respectively 15O~20O, the oblique angle water of inspiration valve seat end face inward flange
The ratio of the width of the length of the straight arm of angle and the inspiration valve seat end face and the oblique angle water of delivery valve seat end face inward flange
The ratio of the width of the length of the straight arm of angle and the delivery valve seat end face is respectively 0.2~0.4.
A kind of above-mentioned Reciprocting piston compressor valve seat end face structure, the inspiration valve seat end face and delivery valve seat end face
Inward flange can be using round, ellipse, kidney-shaped or irregular profiled shape.
A kind of above-mentioned Reciprocting piston compressor valve seat end face structure, the valve plate body are metallic sintered products or steel
Product.
The present invention uses simultaneously due to using above-mentioned technical solution, inspiration valve seat end face and delivery valve seat end face
Corner structure is initially when suction valve chip or exhaust valve plate flop respective valve seat end face with certain speed period
Face contact gradually switchs to line contact with the progress of slap process, and the chamfering structure of valve seat end face significantly reduces valve block
The panting stress for deforming and being subject to improves the reliability of suction valve chip and exhaust valve plate when periodically flopping valve seat end face,
And reduce the noise of valve block slap valve seat.Meanwhile the chamfer design of valve seat end face reduces air-breathing and exhaust to a certain extent
Flow losses in the process, flow conductivity are effectively enhanced, and compressor refrigerating capacity is improved, to improve compressor complete machine energy
Effect ratio.Therefore, it can not only reduce noise while guaranteeing vulnerable part valve block reliability using structure of the invention but also effectively promoted
Complete machine Energy Efficiency Ratio.

Specific embodiment
As shown in Figure 1, Reciprocting piston compressor valve seat end face structure of the present invention includes valve plate body 1, valve plate body 1
For metallic sintered products or steelwork, inspiration valve seat end face 2 and delivery valve seat end face 3 which is provided with.
Please refer to shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the inner edge fate of inspiration valve seat end face 2 and delivery valve seat end face 3
It She You not chamfering structure 4,5.Chamfering structure 4,5 can be fillet or oblique angle.If chamfering structure 4,5 is using fillet, air-breathing
3 inward flange of ratio and delivery valve seat end face of the radius of corner and 2 width of inspiration valve seat end face of 2 inward flange of valve seat end face
It is best that the ratio of radius of corner and 3 width of delivery valve seat end face, which is respectively in the range of 0.2~0.4,.If chamfering structure 4,5 is adopted
When with oblique angle, the angle at oblique angle is respectively 15O~20OIn the range of (angle of bevel be oblique angle bevel edge and level right angle side folder
Angle), and the ratio of the length on the oblique angle level right angle side of 2 inward flange of inspiration valve seat end face and 2 width of inspiration valve seat end face, and
The length on the oblique angle level right angle side of 3 inward flange of delivery valve seat end face and the ratio of 3 width of delivery valve seat end face is respectively 0.2~
