Abstract
本实用新型公开了一种往复式压缩机阀板，其多个排出孔和多个吸入孔在它们的功能面上包括环形表面精加工部，所述环形表面精加工部能够在其相应阀门受到与其打开相反的压力时优化其相应阀门的就位。
The utility model discloses a valve plate of a reciprocating compressor, wherein a plurality of discharge holes and a plurality of suction holes comprise an annular surface finishing portion on their functional surfaces, and the annular surface finishing portion can be received on its corresponding valve. Optimize the seating of its corresponding valve when opening the opposite pressure.
Description
Technical field
The utility model relates to a kind of reciprocating compressor valve plates, relate more specifically to a kind of valve plate, tap and suction
The surface finish Ministry of worker for entering hole is particularly suitable for optimizing the corresponding dump valve of receiving and inlet valve.
Background technique
As it is well known to the skilled in the art, most of dynamic compression of refrigerant fluid is in reciprocating compressor
It is established by operation dump valve and inlet valve, the dump valve and inlet valve are mounted on valve plate, and the valve plate setting exists
The free end of compression cylinder.In general, dump valve is directed toward the "outside" side of valve plate (towards the multiple chambers limited on compressor head
Side), and inlet valve is directed toward the inside (side on the inside of the compression cylinder towards compressor) of valve plate.In general, traditional
The tap and inlet hole of valve plate only include cylindrical hole.
It means that in general, the edge of each tap and inlet hole includes the edge of circular arrangement, the edge
It is limited by approximate right angle.
Therefore, once being placed on their corresponding holes, each (it is discharged or sucks) sealing area of valve and adjacent to it
The entire scope of the valve plate of corresponding aperture is physically contacted.
On the other hand, when valve is by opposite pressure is opened with it, the seal area of each (discharge or sucking) valve
Domain tends to flexure and only establishes with the edge of its corresponding aperture be physically contacted.In view of the edge in hole has its manufacturing process intrinsic
Geometrical defect, valve seal region is not ideal, therefore hinders all optimum operations of compressor.
In this sense, when seeking scheme for the scene that is discussed, the utility model comes into being.
Utility model content
The all purposes of the utility model discussed realizes that the valve plate includes and discharge by reciprocating compressor valve plate
The side of system cooperation and the side and at least one tap that cooperate with multiple inlet valves and at least one inlet hole.Also
Imagine at least one recess portion to cooperate in the side and multiple dump valves cooperated with discharge system, for accommodating at least one valve
Stop part.
According to the utility model discussed, at least one tap includes annular in the recess portion cooperated with multiple dump valves
The surface finish Ministry of worker.
Moreover, in preferred and unrestricted mode, at least one inlet hole exists according to the utility model discussed
Side with inlet valve cooperation includes the annular surface finishing Ministry of worker, and includes at least on the side cooperated with multiple dump valves
One adjacent recess portion.
Detailed description of the invention
The utility model discussed will especially be described in detail on the basis of following illustrative embodiments, in which:
Fig. 1 shows one cooperated according to multiple dump valves of the utility model and reciprocating compressor valve plate that are discussed
Side；
Fig. 2 shows one cooperated according to multiple inlet valves of the utility model and reciprocating compressor valve plate that are discussed
Side；
Fig. 3 and Fig. 4 respectively illustrates the cut-off of the cut-off instruction and reciprocating compressor valve plate of reciprocating compressor valve plate.
Specific embodiment
As it is known by the man skilled in the art, when in the closed position, multiple dump valves of reciprocating compressor and multiple
Inlet valve is easy to be opened opposite pressure by with it.In this regard, the utility model is intended to disclose a kind of valve plate, more
A tap and multiple inlet holes include the annular surface finishing Ministry of worker, the annular surface finishing Ministry of worker on their functional surfaces
It can be in its respective valves by optimizing the in place of its respective valves when opening opposite pressure with it.
It as depicted in figs. 1 and 2, include matching with discharge system as the reciprocating compressor valve plate of the purpose of this utility model
The side (11) of conjunction and the side (12) cooperated with multiple inlet valves.It is also provided with multiple taps (2), multiple inlet holes (3)
With multiple fixation holes (5).Furthermore, it is also contemplated that recess portion (4) cooperates in the side (11) and multiple dump valves cooperated with discharge system,
For accommodating at least one valve stop part.
According to the utility model discussed, at least one tap (2) includes that annular surface finishes in recess portion (4)
Portion, the annular surface finishing Ministry of worker are obtained by usual processing technology.In addition, according to the utility model discussed, at least one
A inlet hole (3) by preferably with it is infinite in a manner of the side (12) cooperated with multiple inlet valves include annular surface finishing
Portion, and include adjacent recess portion (31) in the side (11) cooperated with discharge system.
About the annular surface finishing Ministry of worker on the side of recess portion (4) (12) and side (11), it has been found that they incline
To the contact between permission valve and the edge in each hole more evenly.About adjacent multiple recess portions (31), it has been found that it
Tend to optimize inlet valve opening, so as to compression circulation these time-optimized compressors consumption.
Have been described and illustrate the various embodiments of discussed utility model, it should be appreciated that the protection model discussed
It encloses and may include other possible modifications, which is only limited by the content of claim, and the hand including that may be equal with it
Section.
Claims (2)
