Description
Technical field:
The utility model is about liquid regulator, particularly the throttling arrangement of using about refrigeration machine.
Background technology:
Refrigeration unit generally adopts choke valve to regulate the flow of refrigerant fluid, since the complex structure of choke valve own, fragile again leakage.And existing choke valve is one-way throttle valve, the flow direction to the refrigerant fluid has requirement, when needing refrigerant, refrigeration system does two-way flow when adapting to different operating mode, usually in system, be arranged in parallel two various flows to choke valve, adopt a unlatching, another mode of closing to operate operation, this just makes that system architecture is numerous and diverse, operation inconvenience.
The utility model content:
The utility model purpose is to provide a kind of refrigeration machine throttling arrangement, solve using same throttling arrangement, when flowing forward or backwards, all can carry out effective throttling action by the flow direction of refrigerant voluntarily at the refrigerant fluid.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of refrigeration machine throttling arrangement is characterized in that: this throttling arrangement is arranged on two in the refrigerator system refrigerant fluid circuit fixed restriction orifice plates that keep at a certain distance away, the slip restricting orifice and a stop of placing restrictions on slip restricting orifice stroke that can slide between these two fixed restriction orifice plates; This fixed restriction orifice plate has centromere discharge orifice that diameter is d and the several planet throttle orifices that dispose around this centromere discharge orifice; It is d that this slip restricting orifice has diameter
1The centromere discharge orifice; The diameter d of tangent diameter of a circle D＞this slip restricting orifice centromere discharge orifice with counting the planet throttle orifice
1The diameter d of＞this fixed restriction orifice plate centromere discharge orifice.
The technical solution of the utility model further is: this stop is fixed on this slip restricting orifice one side, and perhaps this stop is fixed on the inwall of the refrigerant fluid circuit that is close to a side fixed restriction orifice plate.
Further again: the head piece area of this fixed restriction orifice plate is 2.0～3.0mm
2/ kw refrigerating capacity, the head piece area of slip restricting orifice is 0.3～0.5mm
2/ kw refrigerating capacity.
The beneficial effects of the utility model are:
1. compare with the one-way throttle valve of valve type, simple in structure, not fragile.
2. utilize the various flows of refrigerant fluid when cold machine state and warm-up mode to the thrust that is produced, promote slip restricting orifice left and right moving between two fixed restriction orifice plates, because the existence of stop, the slip restricting orifice does not lean on mutually mutually with two fixed restriction orifice plates during cold machine, and the slip restricting orifice leans on mutually with one of them fixed restriction orifice plate during warming-up, and the area of both throttling passages is inequality.Therefore throttling arrangement of the present utility model can be realized two-way throttling action.
3. this bidirectional throttle is automatically to realize, artificial switch operation, and control freely.
Description of drawings:
The schematic diagram that Fig. 1 is a kind of structure of the present utility model when the cold machine state of system.
Fig. 2 is the schematic diagram of structure shown in Figure 1 when warm-up mode.
Fig. 3 is the cutaway view of A-A mark among Fig. 1.
The specific embodiment:
See also Fig. 1 to shown in Figure 3, throttling arrangement of the present utility model is arranged on two the fixed restriction orifice plates 1 in the refrigerator system refrigerant fluid circuit 4, a slip restricting orifice 3 and a locator 2.Wherein two fixed restriction orifice plates 1 in a certain distance apart from one another, in refrigerant fluid circuit 4, form a fluid choke zone, the centromere discharge orifice 11 that on each fixed restriction orifice plate 1 diameter to be arranged be d, with several planet throttle orifices 12 around 11 configurations of this centromere discharge orifice, these several planet throttle orifices 12 are that the basic circle 13 of D is tangent with diameter respectively; The head piece area that each fixed restriction orifice plate 1 is made up of centromere discharge orifice 11 and planet throttle orifice 12 and the refrigerating capacity of refrigeration machine are complementary, and are 2.0～3.0mm
2/ kw refrigerating capacity.This slip restricting orifice 3 is positioned at the fluid choke zone that two fixed restriction orifice plates 1 surround, and it is provided with a diameter is d
1 Centromere discharge orifice 31, the head piece area of this centromere discharge orifice 31 also with the refrigerating capacity of refrigeration machine coupling, be 0.3～0.5mm
2/ kw refrigerating capacity.This stop 2 is arranged on a side of slip restricting orifice 3, this stop 2 is the thin-walled hollow tubular in the present embodiment, form one with slip restricting orifice 3, to help guided slidable restricting orifice 3 slippage in refrigeration matchmaker fluid circuit 4, but this stop 2 also can be the projection that is fixedly installed on refrigerant fluid circuit 4 inwalls of the contiguous side fixed restriction orifice plate 1 of this fluid choke zone, to realize that this slip restricting orifice 3 slides into when being blocked by this projection to this side fixed restriction orifice plate 1,1 of the fixed restriction orifice plate of slip restricting orifice 3 and this side still has enough spatial separation, makes planet throttle orifice 12 and centromere discharge orifice 11 on the fixed restriction orifice plate 1 of this side not covered.
Referring to Fig. 1, when refrigeration unit during in the operation of cold machine state, the refrigerant fluid flows from right to left, slip restricting orifice 3 is pushed to left slippage by the refrigerant fluid, until stop 2 and left side fixed restriction orifice plate 1 against, the stop 2 that the restricting orifice 3 that perhaps slides is fixedly installed on contiguous left side fixed restriction orifice plate 1 stops, the restricting orifice 3 that slides this moment does not contact mutually with the fixed restriction orifice plate 1 of both sides, has formed one group of throttling arrangement by two fixed restriction orifice plates 1 and slip restricting orifice 3 series connection.Simultaneously the aperture of centromere discharge orifice 11 on the fixed restriction orifice plate 1 on right side and planet throttle orifice 12 forms fluid-tight, and the fixed restriction orifice plate 1 step-down throttling through slip restricting orifice 3 and left side reaches the purpose of regulating flow by the dynamic equilibrium of refrigerant.
Referring to Fig. 2, when unit when warm-up mode moves, the refrigerant fluid flows from left to right, promotes 3 slippages to the right of slip restricting orifice, because stop 2 is one-sided settings, so slip restricting orifice 3 and right side fixed restriction orifice plate 1 are superimposed.At this moment, the aperture of left side fixed restriction orifice plate 1 is by fluid-tight, and the fixed restriction orifice plate 1 on right side and slip restricting orifice 3 only stay the centromere discharge orifice 11 of fixed restriction orifice plate 1 after superimposed and carry out the step-down throttling, because the diameter d of this centromere discharge orifice 11 is less than the diameter d of the centromere discharge orifice 31 of slip restricting orifice 3
1, therefore reach the requirement that reduces the warm-up mode cold medium flux.
The refrigeration unit of using throttling arrangement of the present invention is when fully loaded utilization, and the static pressure that the liquid-column height of fluid-tight side produces will be fully loaded with required refrigerant liquid and be pushed to second restricting orifice from first restricting orifice (flowing to by refrigerant); The liquid-column height of fluid-tight drops to fully loaded 1/4 when unit moves semi-load, because the deficiency of static pressure, refrigerant by first restricting orifice is half of full load, pressure reduction changes and to cause refrigerant liquid to produce flass between these the first and second two restricting orifices, a large amount of sudden strain of a muscle gas is mixing liquid refrigerants by second restricting orifice, therefore coolant quantity is also reduced to half thereupon, has realized the throttling function that random groups load size is regulated the refrigerant consumption voluntarily.
