In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Referring to FIG. 1, Fig. 1 is a kind of structural schematic diagram of specific embodiment of refrigerator refrigeration system provided by the present invention.
In the embodiment, refrigerator refrigeration system includes compressor 101, condenser 102 and evaporator 103, wherein condenser
102 entrance is connected with the outlet of compressor 101, and the outlet of evaporator 103 is connected with the entrance of compressor 101.
The refrigerator refrigeration system further includes the valve gear 100 being set between condenser 102 and evaporator 103.
Please also refer to Fig. 2, Fig. 2 is a kind of diagrammatic cross-section of specific embodiment of valve gear in Fig. 1.
As shown, the valve gear 100 includes driving part and valve base part 20, wherein valve base part 20 has import
221 and outlet 222, import 221 is connected to the valve chamber R1 of valve gear.
The valve gear 100 further includes the sliding block 30 supported by valve base part 20, bottom surface and the valve base part 20 of sliding block 30
Top surface is bonded.
The sliding block 30, which has, rotates around it center flow path portion circumferentially and closure part, wherein circumferentially, flow path portion
Circulation area is different, and flow path portion is connected to valve chamber R1.
Driving part can drive 30 opposite valve seat component 20 of sliding block to rotate, so that flow path portion is connected to outlet 222, to
It is connected to import 221 and outlet 222, or closure part is made to close outlet 222, to separate import 221 and outlet 222.
It is appreciated that distance of the flow path portion away from 30 center of rotation of sliding block, flow path portion when sliding block 30 should be enable to rotate
It is connected to outlet 222.
As above, which is equipped with valve gear 100 between condenser 102 and evaporator 103, passes through valve gear
100 flow into the cold medium flux of evaporator 103 to adjust；Wherein, the part design for adjusting flow is sliding block by valve gear 100
Structure, circumferentially arranged flow path portion and closure part on sliding block 30, wherein flow path portion is connected to valve chamber R1, valve base part 20
Import 221 is also connected to valve chamber R1, drives the rotation of sliding block 30 to make the outlet of flow path portion and valve base part 20 by driving part
222 connections to make import 221 be connected to outlet 222, or make closure part close outlet 222, to make import 221 and go out
Mouthfuls 222 are separated, in this way, by the rotation of 30 opposite valve seat component 20 of sliding block come realize import 221 and outlet 222 connection or
Partition, makes valve gear 100 have the function of Close All, and the case where be not in stuck failure when fully closed, in this way, working as ice
After the compressor 101 of case refrigeration system is shut down, it can realize that 102 pressurize of condenser reduces energy consumption.
In addition, circumferentially, the circulation area of flow path portion is different, in this way, being rotated by sliding block 30, makes 30 upper runner portion of sliding block
Different location 222 be connected to outlet, the adjusting of flow is realized with this, because the circulation area of flow path portion circumferentially is easy to set up
And adjusting, it can be according to the smaller of system requirements setting, so being easy by the setting of the circulation area of 30 flow path portion of sliding block will

Entrance be connected, capillary 151 is wound in muffler 152, as shown in Figure 1.
The structure design of the heat exchanger 105 is using the high temperature refrigerant between condenser 102 and evaporator 103 come heating evaporation
The low temperature refrigerant that device 103 flows out can make refrigerant system configurations more simple and compact to avoid additional setting heating source.
It should be noted that as above after design, although being provided with capillary between condenser 102 and evaporator 103
151, it will be appreciated that the capillary 151 has not had substantive throttling function, only used as heat exchange function.
Specifically, it being wound in muffler 152 in order to facilitate capillary 151, the aperture of capillary 151 smaller can be arranged, than
Such as 0.7mm, it should be understood that throttling that is too small, and influencing valve gear 100 can not be arranged in the aperture of capillary 151, specifically,
The caliber setting of capillary 151 should make its circulation area not less than the maximum flow area of the flow path portion of valve gear 100.
In specific scheme, device for drying and filtering 104 is additionally provided between condenser 102 and capillary 151, to filter refrigerant
In impurity.
Accurate adjust of the refrigerator refrigeration system of the present invention, cold medium flux mainly passes through what valve gear 100 was realized, below
Each component of valve gear 100 is illustrated emphatically.

The structural schematic diagram of sliding block another kind angle；Fig. 5 is the vertical view of sliding block shown in Fig. 2；Fig. 6 be Fig. 5 in A-A to section show
It is intended to.
In specific embodiment, the flow path portion of sliding block 30 is specially the not exactly the same runner hole 31 in multiple apertures, specifically
Ground, multiple runner holes 31 are circumferentially arranged around the center of rotation of sliding block 30 in arcuation, in this way, between two runner holes 31 of outer end
Position formed sliding block 30 closure part.
In scheme shown in Fig. 4 and Fig. 5, the flow path portion of sliding block 30 is set there are five runner hole 31, with visual angle shown in Fig. 5,
Along clockwise direction, five runner holes 31 are followed successively by 31a, 31b, 31c, 31d and 31e.
In illustrated scheme, the aperture of five runner holes 31a, 31b, 31c, 31d and 31e are incremented by successively, and adjacent two runner
Angle between hole 31 is equal, that is to say, that on the arc section in arrangement runner hole 31, multiple runner holes 31 are uniformly arranged.This
After sample design, sliding block 30 often turns over identical angle, i.e., is once adjusted to flow, convenient for the operation to valve gear 100.
As above, flow path portion is set as to the structure in multiple runner holes 31, the hole of number and each runner hole 31 to runner hole 31
Diameter is easy to control, convenient for controlling flow, to meet the demand for control of refrigerator and similar small refrigeration systems.Such as a kind of tool
In body embodiment, the aperture of runner hole 31a, 31b, 31c, 31d and 31e are set as 0.15mm, 0.18mm, 0.21mm successively,
0.24mm, 0.27mm.
It is appreciated that in practice, when arrangement, the aperture in each runner hole 31 can be irregular, in addition, in arrangement runner hole 31
Arc section on, multiple runner holes 31 can arrange uneven.Only in contrast, rule, uniformly arrangement as illustrated, more
Convenient for the control to product.
Further, with reference to figure 4, multiple inner groovies 35 are offered in the bottom surface of sliding block 30, respectively with multiple runner holes 31
Position correspond to, and the size of each inner groovy 35 is all higher than corresponding runner hole 31.
