The exhaust outlet 11 of compressor 10 is connected with second adjusting part 70 by blast pipe 17, forms second space 75 between the bottom of described second cylinder body 71 and described second piston 72, and the gas at exhaust outlet 11 places feeds in second space 75 by blast pipe 17.Blast pipe 17 is connected in the exhaust outlet 11 of described second adjusting part 70 and described compressor 10.Described second adjusting part 70 comprises also and is arranged at outside described second cylinder body 71 and second tube connector 76 that is connected with described second space 75 that blast pipe 17 is connected on second tube connector 76.Described blast pipe 17 is provided with second block valve 77, in order to connect or to block the medium in the blast pipe 17.
Described throttle seat 50 comprises mount pad 52 and is covered in lid 53 on the described mount pad 52.Described mount pad 52 comprises plate body 54, two the first side walls 55 that are oppositely arranged and 2 second sidewalls 56 that are oppositely arranged, described two the first side walls 55 and described 2 second sidewalls 56 are extended in the same way by the periphery of described plate body 54 and form, the length direction of described the first side wall 55 is consistent with the glide direction of described restricting orifice 41, described first cylinder body 62 is installed on wherein on one second sidewall 56, and described second cylinder body 71 is installed on other one second sidewall 56.Offer the wherein through hole 51 in described two through holes 51 on the described lid 53, offer the other through hole 51 in described two through holes 51 on the plate body 54 of described mount pad 52.The both sides up and down of described restricting orifice 41 contact with the inner surface of described two the first side walls 54 respectively, so that restricting orifice 41 is more stable slidably in throttle seat 50.
Before air-conditioning system 100 starts, because high-pressure gas pressure is identical with low-pressure gas pressure, utilize this moment first flexible member 65 and second flexible member 74 by first piston bar 64 and second piston rod 73 restricting orifice 41 to be controlled state before air-conditioning system 100 starts respectively, as shown in Figure 4, at this moment, area overlapping on described throttle orifice 42 and the fluid flow direction of described through hole 51 in described pipeline 13 is the 20%-30% of the sectional area of described throttle orifice 42, can not cause compressor 10 liquid supply rates excessive too greatly because of the aperture of the throttle orifice 42 of restricting orifice 41 when system starts, and cause compressor 10 absorbing gas belt liquid phenomenons.Behind the unit starting, along with the rising of high-pressure gas pressure and the reduction of low-pressure gas pressure, gases at high pressure act on the pressure F1 that pressure M1 on second piston 72 and low-pressure gas act on the first piston 63 and also change thereupon, when the pressure M1 that gases at high pressure act on second piston 72 increasing, low-pressure gas act on the first piston 63 pressure F1 more and more hour, the pressure that second flexible member 74 produces is designated as M2, the pressure that first flexible member 65 produces is designated as F2, according to dynamic balance condition: M1=F1+M2+F2, this moment, restricting orifice 41 will constantly be moved to the left, new equilbrium position of final arrival, when the difference of the pressure of the pressure of gases at high pressure and low-pressure gas is enough big, restricting orifice 41 can slide into high order end, the aperture of the throttle orifice 42 of restricting orifice 41 just overlaps with the aperture of the through hole 51 of throttle seat 50, at this moment, on described throttle orifice 42 and the fluid flow direction of described through hole 51 in described pipeline 13 overlapping area be described throttle orifice 42 sectional area 100%, that is to say, the throttling latus rectum of whole throttling arrangement is exactly the latus rectum of restricting orifice 41, also be the limiting aperture of this throttling arrangement, as shown in Figure 5.In system's running, restricting orifice 41 can be regulated rational restricting orifice 41 positions according to M1, F1, M2, F2, to reach optimal operational condition.
This restricting orifice 41 also needs to improve in conjunction with corresponding automatically controlled program the place of its deficiency in the practice process; for example; when air-conditioning system 100 when the small pressure difference operating mode is moved; the capacity of system is constant; and the difference of gases at high pressure and low-pressure gas is smaller; re-use the two difference that is applied to the power on the piston and regulate the position of restricting orifice 41; throttle diameter after just causing probably finally stablizing is big inadequately; the liquid supply rate deficiency that causes this moment; cause problems such as low-voltage variation; control the pressure of low-pressure gas so need automatically controlled program; need to disconnect the path that low-pressure gas enters first adjusting part 61 this moment; i.e. first block valve, 16 work; only utilize the pressure of gases at high pressure to promote restricting orifice 41; behind the Spring balanced of the pressure of gases at high pressure and second flexible member 74, restricting orifice 41 can reach the optimum position, in case situations such as low-voltage variation appear in locking system.When system moves under big pressure reduction operating mode, the liquid supply rate of system is excessive, need to disconnect the path that gases at high pressure enter second adjusting part 70 this moment, i.e. second block valve, 77 work, only utilize the pressure of low-pressure gas to promote restricting orifice 41, and then dwindle the fluid flow that flows through described throttling arrangement, prevent the contracting of compressor band hydraulic pressure.
Existing throttling arrangement generally all is the single orifice plate throttling, the fixing back of its throttle diameter just can not changed again, system can not change in running yet, it is excessive to appear under some little load condition liquid supply rate so, cause the contracting of system band hydraulic pressure, and then cause compressor 10 seize to occur, phenomenon such as burn.And adjustable throttling arrangement 40 of the present invention can be regulated flow automatically under operating modes such as start-up course or sub-load process, when satisfying each operating mode operation of system, the assurance system little load operation during the stage throttling arrangement regulate the latus rectum size automatically, security of system is stably moved, prevent excessive because of liquid supply rate, cause compressor 10 seizes that band hydraulic pressure contracting causes, phenomenon such as burn.
In sum, beneficial effect of the present invention:
1. the present invention can prevent that compressor 10 band hydraulic pressure contractings, race wet goods phenomenon that the operation of band liquid causes appear in locking system in start-up course.
2. the present invention can make system regulate the flow of the liquid that flows through throttling arrangement automatically in running, allows system move under best and safest state.
3. the present invention can use first adjusting part 61 separately or use second adjusting part 70 separately, the flow size that also can use the mode of first adjusting part 61 and second adjusting part 70 to regulate the liquid that flows through throttling arrangement simultaneously.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
