Head K direction enters compressibility 2 and is compressed, and low pressure refrigerant A is compressed into high pressure refrigerant B, finally will from high-pressure exhaust 21
Refrigerant is discharged, and forms a complete refrigerant compression process.
It is provided with scroll plate (also known as whirlpool disk) 4, structure such as Fig. 2～Fig. 4 of end face seal between traditional whirlpool disk in compressibility 2
Shown, sealing strip 5 is filled up completely with the seal groove in full scroll plate 4, and the face projecting by sealing strip 5 to seal, and plays compression process
Middle solve the problems, such as interior leakage between different compression chambers.
Above-mentioned sealing structure fully relies on sealing strip and exceeds some surpluses of end face to seal, and uses with long,
Sealing strip fair wear and tear, ultimately results in leakage in occurring between each compression chamber, leads to refrigerant compression not exclusively, and impact compressor is overall
Refrigerating capacity and Energy Efficiency Ratio.
Utility model content
The technical problems to be solved in the utility model is the sealing property how lifting end face between swirl compressor spinning disk, makes
Function must be compressed, and using the longer time, refrigeration will not decline.
In order to solve above-mentioned technical problem, the technical solution of the utility model is to provide to hold between a kind of swirl compressor spinning disk
Face sealing structure, including scroll plate, the end face of scroll plate is provided with seal groove, be provided with sealing strip in seal groove it is characterised in that：
Gap is left between described seal groove and sealing strip bottom；One end of described seal groove is provided with and the insertion of described gap, is used for
Be passed through the refrigerant after compression with by described sealing strip up lifting so that described sealing strip is complete all the time with another vortex tray bottom
The hole of contact.
Preferably, the width in described hole is more than described seal groove；The depth in described hole is identical with described seal groove.
Preferably, described sealing strip and seal groove superstructure match, but the depth of described seal groove is more than sealing strip.
Preferably, described seal groove side is provided with step, and described sealing strip side also is provided with matching with described seal groove
Step.
Preferably, described seal groove both sides are provided with step, and described sealing strip both sides also are provided with matching with described seal groove
Step.
When compressor is in operating, scroll plate compression refrigerant, the high pressure refrigerant after simultaneously compressing is from seal groove one end
Hole enter the bottom space of seal groove, using high pressure refrigerant by sealing strip up lifting, so that sealing strip and another whirlpool
Capstan bottom completely attaches to all the time.
The utility model passes through to open a seal groove with the level on the line end face of compressor whirlpool, using high pressure refrigerant
Sealing strip being lifted, thus improving end face seal between the disk of whirlpool, the sealing of scroll compressor compresses system can be made more may be used
Lean on, sealing will being led to because use time is permanent to be deteriorated, improving the refrigeration under long-time use it is ensured that pressing
The pressure at expulsion of contracting machine, increased the service life of compressor.

Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than restriction scope of the present utility model.In addition, it is to be understood that in the content having read the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment 1
The structural representation of end face seal between the swirl compressor spinning disk that Fig. 5 provides for the present embodiment, in conjunction with Fig. 6～Fig. 8,
Between described swirl compressor spinning disk, the structure of end face seal is to open a seal groove with the level on the end face of scroll plate 4
41, open a hole 42 being more than sealing well width in one end of this seal groove 41, the depth in hole 42 is identical with seal groove 41；Exist again
The built-in sealing strip 5 with the level of seal groove 41, the depth of seal groove 41 is more than sealing strip 5, makes bottom and the sealing of sealing strip 5
Groove 41 forms a space.
Wherein, seal groove 41 only side band step, sealing strip 5 also corresponding only side band step.To be sealed by step
Bar lifts so that sealing strip 5 bottom is not contacted with seal groove 41 bottom.
