Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is more specifically described in detail.
Embodiment
As shown in Figures 1 to 3.The invention discloses a kind of labyrinth type miniflow adjustable valve, including valve sleeve body 1, spool 2；
Valve sleeve body 1 has a valve pocket, spool 2 by can relative to valve pocket axial-movement in the way of be placed in this valve pocket；At valve sleeve body 1
With the corresponding position of 2 two ends of spool, it is respectively equipped with inlet 11 and liquid outlet 12, described valve pocket and the spool 2 of connection valve pocket
The conical structure being shaped as fitting each other.
External peripheral surface along spool 2 is distributed the ring-shaped groove that several is spaced, the interval between each ring-shaped groove
Section forms protruding rib stricture of vagina 21；When downward turn spool 2, when making spool 2 be in open mode, liquid stream is entered valve by inlet 11
Chamber, and the most step by step through ring-shaped groove, in choked flow and the cushioning effect of each road ring-shaped groove, the pressure of liquid stream drops the most step by step
Low, reduce the liquid stream after pressure and finally flowed out by liquid outlet 12.
Described valve pocket and spool 2 step by step less than the tapering of fluid outlet end, are positive cone towards the tapering of liquid stream entrance point
Shape, after making liquid stream be entered valve pocket by inlet 11, enters liquid outlet 1 step by step and flows out after diffusion.
Described valve pocket and spool 2 step by step more than the tapering of fluid outlet end, are back taper towards the tapering of liquid stream entrance point
Shape, after making liquid stream be entered valve pocket by inlet 11, enters liquid outlet 12 and flows out after shrinking step by step.
The surface of described rib stricture of vagina 21 and the inwall of valve pocket are plane contact.The tapering of described valve pocket and spool 2 is 5 °～20 °
In the range of adjust.Depending on the most concrete tapering can require according to concrete application.
The axis perpendicular of the upper side being opened in valve pocket of described inlet 11, its axis and spool 2；Described go out liquid
Mouth 12 is opened in the axis coaxle of the lower end of valve pocket, its axis and spool 2.
The upper end of spool 2 is provided with one handle 3, makes spool 2 axially-movable in valve pocket by rotary handle 3, to change
Gap between surface and the valve pocket internal face of rib stricture of vagina 21, and then realize the regulation of flow.
Use labyrinth type miniflow adjustable valve of the present invention, it is achieved the rate-determining steps of micrometeor is as follows:
When downward turn spool 2, when making spool 2 be in open mode, liquid stream is entered valve pocket by inlet 11, and successively by
Level crosses ring-shaped groove, and in choked flow and the cushioning effect of each road ring-shaped groove, the pressure of liquid stream reduces the most step by step, reduces pressure
After liquid stream finally flowed out by liquid outlet 12, and then realize accurate micrometeor control.
When valve pocket and spool 2 use positive tapered arrangement, after liquid stream is entered valve pocket by inlet 11, in the effect of positive taper
Under, liquid stream enters liquid outlet 12 after spreading step by step and flows out；
When valve pocket and spool 2 inverted cone are arranged, after making liquid stream be entered valve pocket by inlet 11, enter out after shrinking step by step
Liquid mouth 12 also flows out.
As it is shown on figure 3, the laboratory table used is the refrigeration system of a kind of single stage compress, including compressor, condenser, evaporation
The labyrinth type miniflow adjustable valve of device and the present invention.The outlet of compressor connects condenser, after working medium heat exchange within the condenser,
Flow into vaporizer by labyrinth type miniflow adjustable valve and carry out heat exchange, then through gas separation unit, finally return to compressor and complete to follow
Ring.
According to the pressure requirements of different system units, optional a number of miniflow adjustable valve is connected to parts
In, the inverted cone selecting tapering to be 15 ° in present case.It is coupled with between condenser and vaporizer, as cooling flow
J-T choke valve.
According to the requirement of different system, the tapering of valve pocket and spool 2 can be processed as arbitrarily angled, and different taperings can shadow
Ring pressure controlled sensitivity.
The size of tapering determines pressure controlled sensitivity.When cone height is identical, tapering is the biggest, the length in labyrinth
The longest, sensitivity is the biggest, and fine-tuning capability is the strongest；Tapering is the least, and the length in labyrinth is the shortest, and sensitivity is the least, and fine-tuning capability is the most weak.
Suitable body length and tapering are set, different adjustment scope and sensitivity requirement can be realized.Axial movement in cone
In, the rib stricture of vagina 21 of its projection changes with the gap of valve pocket internal face, it is achieved its working medium flow controls.
In choked flow and the cushioning effect of maze-type structure, high pressure flow often cross a rib stricture of vagina 21 will reduce himself pressure
Power, the number of channels of ring-shaped groove is the most, and length is the longest, then the most notable to the reducing effect of power pressure.
As it has been described above, just can preferably realize the present invention.
Embodiments of the present invention are also not restricted to the described embodiments, other any spirit without departing from the present invention
With the change made under principle, modify, substitute, combine, simplify, all should be the substitute mode of equivalence, be included in the present invention's
Within protection domain.
