The quantity of discharge orifice 35 is capable of achieving the purpose of adjusting refrigerant flow rate.
As shown in Fig. 2 the first chamber 31 is placed in the second chamber 32.Will the chamber of two tubulars be arranged
Together, the outside of first chamber 31 is second chamber 32, and the cold-producing medium for flowing out first chamber 31 is directly entered second chamber 32
And flow away from valve export；The volume of second chamber 32 is larger, and the pressure into the cold-producing medium of second chamber 32 reduces suddenly, realizes
The purpose of reducing pressure by regulating flow.
Further, spring 34 is fixed with second seed cell 312, the spring 34 is connected with the piston plate 33.
One end of spring 34 is connected with the inwall of the second seed cell 312, and the other end of spring 34 is connected with piston plate 33；When piston plate 33 to
When moving away from valve inlet direction, spring 34 is compressed, when the active force and the pressure of the inner refrigerant of the first seed cell 311 of spring 34
When power is mutually balanced, piston plate 33 is no longer moved, and the total amount in the unit interval into the cold-producing medium of second chamber 32 keeps stable；
In the same manner, when the pressure drop of the inner refrigerant of the first seed cell 311, the active force of spring 34 is bigger than normal, and spring 34 drives piston plate 33
To moving near the direction of valve inlet, while the deformation that pushes away of spring 34 is gradually reduced, the motive force for being provided also is gradually reduced,
When spring 34 active force again with the first seed cell 311 in cold-producing medium provide pressure reach balance when, piston plate 33 is again
Reach stable state.A stable state is moved to by arrange that spring 34 makes piston plate 33, under making same state
The flow of cold-producing medium keeps stable, while can avoid the frequent movement of piston plate 33 and affect piston plate 33 with first chamber 31
Sealing property.
Preferably, moving direction interval setting of the throttle orifice 35 along the piston plate 33.As long as such piston plate 33
Certain distance is moved through, the first seed cell 311 of connection will change with the quantity of the throttle orifice 35 of second chamber 32, realize system
Cryogen Flow-rate adjustment.Such as：The throttle orifice 35 is linearly distributed along the moving direction of the piston plate 33；Or, it is described
Moving direction helically wire distribution of the throttle orifice 35 along the piston plate 33.The distribution mode of throttle orifice 35 can arbitrarily change,
As long as ensureing that its entirety is the moving direction distribution along piston plate 33, as long as so piston plate 33 produces certain distance
Displacement, the first seed cell 311 of connection will change with the quantity of the throttle orifice 35 of second chamber 32, realize Flow-rate adjustment.Section
The shape of discharge orifice 35 can be：The various structures such as circular, star-like, triangle, ellipse and regular polygon, as long as disclosure satisfy that section
The requirement of stream.
On the whole, the adaptive throttling valve 3 can be automatically adjusted by the pressure change in the first seed cell 311 and enter
The amount of the cold-producing medium of two chambers 32, and simple structure, low cost of manufacture is conveniently widely popularized and uses.
Embodiment two：
Under refrigerating state, when air-conditioning system indoor load changes, the on high-tension side cold-producing medium pressure flowed out by condenser 2
Power can change, and load is higher, and high-pressure side refrigerant pressure is bigger；Based on this principle, as shown in figure 1, the present embodiment is also
There is provided a kind of air-conditioning system, with the adaptive throttling valve 3 as described in embodiment one.When valve inlet is air-conditioning system high pressure
When side refrigerant pressure increases, the first seed cell 311 can increase therewith with the connection area of second chamber 32, and the unit interval is by being somebody's turn to do
The amount increase of the cold-producing medium of adaptive throttling valve 3, is that evaporimeter 4 is taken more colds, to ensure refrigeration.Utilizing should
Adaptive throttling valve 3, can make air-conditioning system realize automatically adjusting refrigerant flow purpose, just can be passed through with relatively low cost
The load of air-conditioning automatically adjusts the flow of cold-producing medium in air-conditioning system so that air-conditioning system can be with the change of environment temperature certainly
Adapt to adjust cold medium flux, the moment ensures the optimal running effect of refrigeration system.
It is concrete as shown in figure 1, the air-conditioning system specifically include by compressor 1, cross valve, condenser 2, evaporimeter 4 and
The refrigeration of the composition of adaptive throttling valve 3 heats loop, in the valve inlet of the adaptive throttling valve 3 and refrigerating circuit

Entrance connection.Under refrigerating state, when the load of air-conditioning system increases, the high-pressure refrigerant that condenser 2 flows out enters from valve
Mouth enters the first seed cell 311, and then under the high pressure effect of the high-pressure refrigerant, piston plate 33 starts movement, the first seed cell 311
Gradually increasing with the connection area of second chamber 32, and then flow into the refrigerant flow of second chamber 32 increases, i.e. unit
Increased by the refrigerant flow of the adaptive throttling valve 3 in time, the amount of the cold-producing medium in the unit interval into evaporimeter 4 increases
Plus, bring more colds into and freezed, reduce the load of air-conditioning system；When the load of air-conditioning system reduces, process is therewith
On the contrary.
When environment temperature is raised, refrigeration system high pressure pressure rise with rising, the now pressure at the two ends of piston plate 33
Balance will be broken, piston plate 33 to the direction away from valve inlet is moved, and the first seed cell 311 is increasing, with the first seed cell
The throttle orifice 35 of 311 connections is more and more, and the cold medium flux of refrigeration system is increasing, and the pressure of high pressure is just more and more lower；And
The power of spring 34 is also increasing with the increase of decrement, when refrigerant high pressure pressure and the power of spring 34 reach balance, piston
Plate 33 is no longer moved, and refrigeration system keeps current optimal refrigerating state operation, it is to avoid HTHP is protected and shutting down to freeze.
Conversely, when the environment temperature decreases, refrigeration system high pressure pressure rise with reduction, now two ends of piston plate 33
Pressure can also break balance, and to moving near the direction of valve inlet, the first seed cell 311 is less and less, and with the first seed cell 311
The throttle orifice 35 of connection is fewer and feweri, and the cold medium flux of refrigeration system is fewer and feweri, and the pressure of high-pressure refrigerant is just more and more lower,
And the power of spring 34 is also less and less with the reduction of decrement, when high-pressure and the power of spring 34 reach balance, piston plate 33
No longer move, refrigeration system keeps current optimal refrigerating state operation, it is to avoid low-temp low-pressure returns liquid and shutting down to freeze.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement and replacement can also be made, these improve and replace
