Abstract
The utility model relates to an exhaust base ring of a compressor. The exhaust base ring is arranged at an upper cylinder cover and a lower cylinder cover of the compressor, and is connected with an exhaust hole in the cylinder cover in an interference fit manner or is directly machined from the cylinder cover; a guide groove for draining and guiding for reducing exhaust pressure loss is formed from the inner diameter of the exhaust base ring to a notch of a valve base; the guide groove is formed in an arc manner along the inner diameter of the exhaust base ring. Compared with the prior art, the exhaust base ring can reduce exhaust pressure loss as the guide groove functioning as draining and guiding is formed from the inner diameter of the exhaust base ring to the notch of the valve base; in addition, as the guide groove does not exceed the top diameter of the exhaust base ring, no leakage is caused when a valve piece is closed.
Description
Technical field
The utility model relates to a kind of compressor assembly, especially relates to a kind of compressor air-discharging seat ring.
Background technique
Rolling piston compressor belongs to positive displacement compressor, the relief opening interference fit of the exhaust seat ring of rotor-type compressor and cylinder cap or directly processed by cylinder cap, pressurized gas after having compressed are discharged by exhaust seat ring endoporus, impact force and gas difference force that simultaneously exhaust seat ring bears valve block, exhaust seat ring prevents that with the composition seal closure cavity such as valve block high pressure gas leakage from entering low-pressure cavity in breathing process in addition.The refrigerant that perfect condition lower compression machine is discharged from exhaust seat ring all points to valve seat indentation, there, and stream is unobstructed like this, and crushing is little.And the refrigerant that existing compressor air-discharging seat ring is discharged spreads to surrounding, stream loss is large.
Application number is the new exhaust seat ring structure that 200720069474.7 Chinese patent discloses rolling piston compressor, the new exhaust seat ring structure of this rolling piston compressor, comprise the exhaust port on the cylinder cap of exhaust seat ring and the rolling piston compressor that interference fit is connected with it, wherein, described exhaust seat ring inwall is cylindrical hole, its outer wall is taper shape or stepped shape, exhaust port on described cylinder cap is corresponding taper shape or the stepped shape coordinating with exhaust seat ring outer wall, because needs additionally carry out fine finishing to the entirety of exhaust port, thereby strengthen fabricating cost.
Model utility content
The purpose of this utility model be exactly provide a kind of convenient guiding air-flow in order to overcome the defect that above-mentioned prior art exists, reduce exhaust crushing, valve block is closed Shi Buhui the compressor air-discharging seat ring leaking is occurred.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of compressor air-discharging seat ring, be arranged on upper cylinder cover and the lower cylinder cap place of compressor, be connected or directly processed by cylinder cap with the relief opening interference fit on cylinder cap, drainage guiding is set can reduces the guiding groove of exhaust crushing thereby the internal diameter of described exhaust seat ring points to valve seat indentation, there, this guiding groove is circular-arc along the internal diameter of exhaust seat ring and offers.
Described guiding groove is the embedded breach being opened on exhaust seat ring internal diameter.
The radian of described guiding groove is no more than the footpath, summit of exhaust seat ring.
Compared with prior art, the utility model points to valve seat indentation, there at exhaust seat ring internal diameter guiding groove is set, and plays the effect of drainage guiding, reduces exhaust crushing, be no more than in addition the footpath, summit of exhaust seat ring due to guiding groove, leak thereby make valve block close Shi Buhui.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure, 1 is that exhaust seat ring, 2 is that guiding groove, 3 is upper cylinder cover.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of compressor air-discharging seat ring, its structure as shown in Figure 1-2, can be arranged on upper cylinder cover and the lower cylinder cap place of compressor, in the present embodiment, exhaust seat ring 1 is arranged on upper cylinder cover 3, and be connected with the relief opening interference fit on upper cylinder cover 3, thereby pointing to valve seat indentation, there, the internal diameter of exhaust seat ring drainage guiding is set can reduces the guiding groove 2 of exhaust crushing, this guiding groove is circular-arc along the internal diameter of exhaust seat ring and offers, furthermore, guiding groove 2 is for being opened in the embedded breach on exhaust seat ring 1 internal diameter.The radian of guiding groove 2 is no more than the footpath, summit of exhaust seat ring, leaks thereby make valve block close Shi Buhui.Owing to pointing to valve seat indentation, there at exhaust seat ring 1 internal diameter, guiding groove 2 is set, thereby can plays the effect of drainage guiding, reduce exhaust crushing.
Claims (3)
1. a compressor air-discharging seat ring, be arranged on upper cylinder cover and the lower cylinder cap place of compressor, be connected or directly processed by cylinder cap with the relief opening interference fit on cylinder cap, it is characterized in that, drainage guiding is set can reduces the guiding groove of exhaust crushing thereby the internal diameter of described exhaust seat ring points to valve seat indentation, there, this guiding groove is circular-arc along the internal diameter of exhaust seat ring and offers.
2. a kind of compressor air-discharging seat ring according to claim 1, is characterized in that, described guiding groove is the embedded breach being opened on exhaust seat ring internal diameter.
3. a kind of compressor air-discharging seat ring according to claim 2, is characterized in that, the radian of described guiding groove is no more than the footpath, summit of exhaust seat ring.
