Embodiment
As shown in Figures 1 to 3.The utility model discloses a kind of labyrinth type miniflow adjustable valve, including valve sleeve body 1, valve
Core 2；Valve sleeve body 1 have a valve pocket, valve element 2 by can relative to valve pocket axial-movement in the way of be placed in the valve pocket；In valve pocket
The corresponding position of body 1 and 2 two ends of valve element, is respectively equipped with the inlet 11 and liquid outlet 12 of connection valve pocket, the valve pocket and
The conical structure for being shaped as fitting each other of valve element 2.
Several spaced ring-shaped groove, the interval between each ring-shaped groove is distributed with along the external peripheral surface of valve element 2
Section forms raised rib stricture of vagina 21；When downward turn valve element 2, when making valve element 2 be in open mode, liquid stream enters valve by inlet 11
Chamber, and successively step by step through ring-shaped groove, the choked flow and cushioning effect in each road ring-shaped groove, the pressure of liquid stream drops step by step successively
It is low, reduce the liquid stream after pressure and finally flowed out by liquid outlet 12.
The valve pocket and valve element 2 are less than step by step the taper at fluid outlet end, as positive cone towards the taper of liquid stream entrance point
Shape, makes liquid stream be entered after valve pocket by inlet 11, liquid outlet 1 is entered after spreading step by step and is flowed out.
The valve pocket and valve element 2 are more than step by step the taper at fluid outlet end, as back taper towards the taper of liquid stream entrance point
Shape, makes liquid stream be entered after valve pocket by inlet 11, liquid outlet 12 is entered after shrinking step by step and is flowed out.
The surface of the rib stricture of vagina 21 is plane contact with the inwall of valve pocket.The taper of the valve pocket and valve element 2 is 5 °～20 °
In the range of adjust.Certainly depending on concrete taper can be required according to concrete application.
The axis perpendicular of the upper side for being opened in valve pocket of the inlet 11, its axis and valve element 2；It is described go out liquid
Mouth 12 is opened in the axis coaxle of the lower end of valve pocket, its axis and valve element 2.
The upper end of valve element 2 is provided with one handle 3, and by rotary handle 3 axially-movable in valve pocket of valve element 2 is made, to change
Gap between the surface of rib stricture of vagina 21 and valve pocket internal face, and then realize the regulation of flow.
Using this utility model labyrinth type miniflow adjustable valve, realize that the rate-determining steps of micrometeor are as follows：
When downward turn valve element 2, when making valve element 2 be in open mode, liquid stream enters valve pocket by inlet 11, and successively by
Level crosses ring-shaped groove, and the choked flow and cushioning effect in each road ring-shaped groove, the pressure of liquid stream is reduced step by step successively, reduces pressure
Liquid stream afterwards is finally flowed out by liquid outlet 12, and then realizes accurate micrometeor control.
When valve pocket and valve element 2 are arranged using positive taper, liquid stream is entered after valve pocket, in the effect of positive taper by inlet 11
Under, liquid stream enters liquid outlet 12 and flows out after spreading step by step；

As shown in figure 3, using laboratory table be a kind of refrigeration system of single stage compress, including compressor, condenser, evaporation
Device and labyrinth type miniflow adjustable valve of the present utility model.The outlet connection condenser of compressor, working medium is changed within the condenser
After heat, vaporizer is flowed into by labyrinth type miniflow adjustable valve and is exchanged heat, then through gas separation unit, finally return to compressor complete
Into circulation.
According to the pressure requirements of different system units, a number of miniflow adjustable valve may be selected and is connected to part
In, the inverted cone that taper is 15 ° is selected in present case.It is coupled between condenser and vaporizer, as cooling flow
J-T choke valves.
According to the requirement of different system, the taper of valve pocket and valve element 2 can be processed as arbitrarily angled, different taper can shadow
The pressure controlled sensitivity of sound.
The size of taper determines pressure controlled sensitivity.When cone height is identical, taper is bigger, the length in labyrinth
Longer, sensitivity is bigger, and fine-tuning capability is stronger；Taper is less, and the length in labyrinth is shorter, and sensitivity is less, and fine-tuning capability is weaker.
Appropriate body length and taper is set, different adjustment scope and sensitivity requirement is capable of achieving.In the axial movement of cone
In, its raised rib stricture of vagina 21 changes with the gap of valve pocket internal face, realizes its working medium flow control.
Choked flow and cushioning effect in maze-type structure, high pressure come flow often cross a rib stricture of vagina 21 will reduce its own pressure
Power, the road number of ring-shaped groove is more, and length is longer, then also more notable to the reducing effect of power pressure.
As described above, just can preferably realize this utility model.
Embodiment of the present utility model is simultaneously not restricted to the described embodiments, and other are any without departing from of the present utility model
Spirit and the change, modification, replacement made under principle, combine, simplify, should be equivalent substitute mode, being included in
Within protection domain of the present utility model.
