Description
Background technology
Referenced patent number be 15933 patent, we describe it is a kind of comprising multiple inlet holes, for closed loop compressor
Inlet valve.The suction of refrigerant and discharge process are circulated in refrigeration systems.Refrigerant is by by being connected to cylinder head
The inlet hole and discharge orifice of valve plate are handled.Inlet hole is processed so that rectangle valve plate has chamber, and side and the valve of chamber
Surface is vertical, and wherein valve surface is parallel.The surface of valve plate is vertical with the outside of valve plate.Valve plate includes two inlet holes, two
The upper surface of individual inlet hole is designed to have the region smaller than the lower surface of intake chamber, and the dividing plate of wherein inlet hole is located at
The centre in two holes.
Referenced patent number is 15933 patent, and in order to improve refrigerant flow, the expansion of inlet hole will be produced limited
The problem of being difficult to mechanical erection in space, and the stress increased during valve opening and closing at inlet valve can cause inlet valve
Failure.In addition, suction may opened and closed by minimizing the block board thickness between two inlet holes in the confined space
Dividing plate is damaged during valve.Therefore, the improvement of refrigerant flow depends heavily on the size of inlet hole.
Therefore, the patent of Patent No. 15933 has defect.Inlet hole on valve plate be processed to have may be by hole
The chamber of tapered slope formation on top.Inlet hole is processed to by rectangle valve plate, and the center line of inlet hole is with (putting down on surface
It is capable) valve surface is vertical.The surface of valve plate is vertical with the outside of valve plate.These chambers form connection between inlet hole.Suction
The surface region --- surface region is less than the lower surface of chamber --- in hole is by turbulization.Flowing is smaller by chamber lower portion
The obstruction of surface region, causes flow path to deviate.This will cause the speed, mass flow and emission factor of suboptimum, and this is
One improvement areas for attracting people's attention.
The new invention has two inlet holes, and inlet hole has larger diameter at top, has in bottom less straight
Footpath, in gradual change (incremental) inclined-plane, the beginning of top edge and the center line in hole are into the angle less than 90 degree.
The inclined-plane will eliminate the friction loss of refrigerant in cylinder, and this will cause the improvement of refrigerant flow and emission factor.
Refrigerant will flow through connecting portion between suction line and the first and second holes.Divider height between hole is equal to valve plate
Highly (referring to the details in complete claim).
The content of the invention
The valve plate for being modified to improve the refrigerant flow of compressor has two inlet holes, and valve plate is located at cylinder
With the end of inlet valve.Two holes have larger diameter at the top of intake panel, have in the bottom of intake panel less straight
Footpath.From plate top, hole gradual change inclined-plane with from plate bottom, hole gradual change inclined-plane into the angle less than 90 degree.
Two holes have standard shape, and the standard shape has the side of a part circular (semi-circular) and opposite side has
Linear shape.
Refrigerant flows through the connecting portion between suction line and the first inlet hole and the second inlet hole.Dividing plate between inlet hole
Keep and valve plate height identical height.
There are a discharge orifice, the center of the dividing plate between the discharge orifice and the first inlet hole and the second inlet hole on valve plate
On the same line.
It is an object of the invention to improve the emission factor of the refrigerant at inlet hole, reduce by the surface of chamber lower portion
Caused turbulent flow smaller than the surface in hole, and increase flow velocity and mass flow.This will make compressor more effectively work.
Invention field
It is a kind of to be related to improvement valve plate to improve the engineering design of the refrigerant flow of compressor.
The complete description of the present invention
Figures 1 and 2 show that the schematic diagram of the valve plate after inlet hole is improved, improving inlet hole (has and connects to increase
It is connected to the cylinder of motor driving piston) refrigerant flow in compressor.Piston is aspirated from the entrance with lower pressure
Refrigerant, and refrigerant is forced into outlet opening, to increase pressure and make refrigerant liquefaction.Refrigerant flows through the suction on valve plate 10
Enter hole and discharge orifice, wherein valve plate is attached to cylinder head portions.The flowing for increasing refrigerant is imitated in the reduction of any suction frictional force
Rate.
Valve plate 10 includes two inlet holes 11,12, and two inlet holes are located at the top of cylinder.First inlet hole and second is inhaled
Enter the chamber 20 that hole is processed to part circular shape, it has larger diameter at top 13 and had in bottom 21 smaller
Diameter, the wherein center line in gradual change inclined-plane and hole is into the angle 23 (Fig. 4) less than 90 degree.First inlet hole and the second inlet hole
The part circular shape of standard is characterised by, the part circular shape is by the arc 14 of side and the structure of linear plane 15 of opposite side
Into.The linear plane in two holes is positioned in parallel with each other.This tapered slope reduces friction loss, improves refrigerant inflow
The efficiency of inlet hole.This will improve compression efficiency by more excellent emission factor.Dividing plate 16 has with the identical of valve plate 10 highly,
Show good intensity.There is a discharge orifice 19 on valve plate 10, the discharge orifice is sucked according to the first inlet hole 11 and second
The identical arrangement mode of dividing plate 16 between hole 12 is positioned.
Fig. 3 and Fig. 4, which show (to see above) as previously described, is processed to the part circular chamber 20 with tapered slope
The viewgraph of cross-section of valve plate 10.
Fig. 5 shows the assembling form of valve plate 10 and suction line 18, the wherein center of suction line 18 and the first inlet hole 11
And the second suction dividing plate 16 between inlet hole 12 is aligned.The opening of suction line 18 is oriented to relative with valve plate 10.Relative
Side, inlet hole is processed to the chamber 20 of inclined part circular, rubs to reduce suction and refrigerant is effectively flowed
Cross cylinder.
Fig. 6 shows that refrigerant flows through the simulation of the first inlet hole 11 and the second inlet hole 12.The outer radius of cold-producing medium stream
Amplified by the tapered slope 20 of the surface region along valve plate 10.This shows its surface district for being designed to effectively utilize valve 10
Domain.Turbulent flow is reduced the figure illustrates the influence due to tapered slope, emission factor and flow velocity are bigger.The reduction of turbulent flow will cause
More preferable compression efficiency.
Fig. 7 shows the results contrast between the valve plate 10 of the present invention and former valve plate, and this compares by agriculture university of Thailand work
Aerospace Engineering system of journey institute (Department of Aerospace Engineering, Faculty of
Engineering, Kasetsart University) carry out.The figure illustrates the model (Kulthon models) and master mould phase
The relatively low turbulence energy of ratio, the turbulent flow chance that showing improved valve plate has is less than master mould.
Fig. 8 shows the form of the same item research carried out by Aerospace Engineering system of engineering college of agriculture university of Thailand.
As a result show, improved valve plate better performances, particularly emission factor increase by 4.37%, this produces bigger refrigerant flow.
