Description
Technical field
The present invention relates to compressor apparatus field, specially a kind of exhaust valve plate structure and one kind are provided with the exhaust valve
The compressor of chip architecture.
Background technique
Existing compressor valve plate, generally narrow portion flat structures, and valve block interconnecting piece form is fairly simple, is typically easy to
Flutter and time-delay closing are generated, the noise between 630~1600Hz, overall noise of the band noise to compressor are generated
It can influence serious.The mode for increasing the thickness of compressor valve plate is generallyd use in the related technology, improves the intrinsic of compressor valve plate
Frequency increases cost, and valve block thickeies the performance that can also reduce compressor.
Summary of the invention
The problem of for background technique, the present invention provides a kind of exhaust valve plate structures and one kind to be provided with this
The compressor of exhaust valve plate structure adjusts the Constrained mode frequency of valve block using the relief fabric of narrow portion, in compressor operating
Reduce the flutter of compressor, to reduce the high-frequency noises of compressor, and in the case where not reducing throttle slice thickness, mentions
The efficiency of compressor is risen.
To achieve the above object, the invention provides the following technical scheme: a kind of exhaust valve plate structure, including valve block ontology,
The valve block ontology includes head, narrow portion and the flat part of integral structure, is offered on the flat part for connecting pressure
Contracting machine limits the through-hole of lift device, and the narrow portion is in relief fabric.
As a preferred technical solution of the present invention, the narrow portion includes at least one section of lug boss.
As a preferred technical solution of the present invention, the lug boss semicircular in shape, rectangle or sector structure.
As a preferred technical solution of the present invention, pass through fillet mistake between the lug boss and head and flat part
Cross connection.
As a preferred technical solution of the present invention, the height D of the lug boss is full in the thickness H of the valve block ontology
Sufficient D < H < 4D.
As a preferred technical solution of the present invention, the narrow portion layer serpentine structure.
A kind of compressor is provided with exhaust valve plate structure described above.
Compared with prior art, the beneficial effects of the present invention are: the present invention is by having set the narrow portion of valve block ontology to
Shape structure is lied prostrate to adjust valve block rigidity, to adjust the intrinsic frequency of exhaust valve plate, avoids the operation frequency multiplication of compressor, so that pressure
Contracting machine valve block reduces the structural noise generated at valve block and pneumatic noise in compressor operating, reduces compressor and integrally makes an uproar
Sound, terminal with compact integral structure is practical, and cost is low, has more vast market prospect.
