Abstract
The utility model discloses a concave valve plate of a refrigeration compressor. The concave valve plate comprises a concave valve plate body (1), wherein an air inlet valve port (2) is formed in the concave valve plate body (1); a concave platform (3), which has a diameter greater than that of the air inlet valve port (2), is formed on the upper part of the air inlet valve port (2); and the concave platform (3) and the air inlet valve port (2) are coaxial with each other. By the concave valve plate of the refrigeration compressor, the integrity of the air inlet valve port can be ensured.
Description
Technical field:
The utility model relates to a kind of compressor valve board, specifically is the recessed valve plate of a kind of refrigeration compressor.
Background technique:
Compressor valve board is one of strength member in the refrigeration compressor, and the refrigeration of compressor is had immeasurable effect.Existing compressor has adopted recessed valve plate basically with valve plate, makes it have better refrigeration.In the working process of valve plate, the integrity of air valve mouth is of crucial importance, otherwise will influence the sealing between valve block and the valve plate.Then, the intake valve port of existing valve plate owing to have matching gap between plug and the drift, can produce the part burr when compression moulding, and it is damaged to cause product that intake valve port is occurred.Like this, the tightness that makes product is affected, and then has influence on the refrigeration performance of compressor.
The model utility content:
The technical problem that the utility model will solve is that a kind of recessed valve plate of refrigeration compressor that can guarantee the intake valve port integrity is provided.
The technical solution of the utility model is; A kind of recessed valve plate of refrigeration compressor with following structure is provided; It comprises recessed valve plate body; Described recessed valve plate body is provided with intake valve port, and the top of described intake valve port forms the concave station of a diameter greater than the intake valve port diameter, this concave station and intake valve port coaxial line.
After adopting above structure; Compared with prior art, the utlity model has following advantage: because of the top of intake valve port forms the concave station of a diameter greater than the intake valve port diameter, and this concave station and intake valve port coaxial line; After concave station is provided with like this; Intake valve port just can not produce burr when compression moulding, and then has avoided the damaged generation of intake valve port, has guaranteed the refrigeration performance of compressor effectively.
Description of drawings:
Fig. 1 is the main TV structure schematic representation of the recessed valve plate of refrigeration compressor of the utility model.
Fig. 2 is that A-A among Fig. 1 is to the broken section structural representation.
Shown in the figure: 1, recessed valve plate body, 2, intake valve port, 3, concave station.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As depicted in figs. 1 and 2, the recessed valve plate of the refrigeration compressor of the utility model, it comprises a recessed valve plate body 1.Described recessed valve plate body 1 is provided with intake valve port 2 and gives vent to anger valve port (unmarked).
Different with existing technology is that the top of described intake valve port 2 forms the concave station 3 of a diameter greater than intake valve port 2 diameters, and this concave station 3 and intake valve port 2 coaxial lines.
The recessed valve plate of the refrigeration compressor of the utility model is because of being provided with concave station, and when compression moulding, intake valve port just can not produce burr like this, and then has avoided the damaged generation of intake valve port, has guaranteed the refrigeration performance of compressor effectively.
Claims (1)
1. recessed valve plate of refrigeration compressor; It comprises recessed valve plate body (1); Described recessed valve plate body (1) is provided with intake valve port (2); It is characterized in that the top of described intake valve port (2) forms the concave station (3) of a diameter greater than intake valve port (2) diameter, this concave station (3) and intake valve port (2) coaxial line.
