As shown in Figure 10, expansion switch valve mentioned above can include valve body 500, wherein, inner flow passage on the valve body 500 formed with import 501, outlet 502 and connection between import 501 and outlet 502, first valve element 503 and the second valve element 504 are installed on inner flow passage, first valve element 503 causes import 501 directly to be connected with outlet 502 or disconnect connection, and the second valve element 504 causes import 501 to be connected with outlet 502 by restriction 505 or disconnect connection.
Wherein, " the directly connection " that first valve element is realized refers to that the cooling agent from the entrance of import 501 of valve body 500 can cross the first valve element and the outlet 502 of valve body 500 is insusceptibly flowed directly to by inner flow passage, and " the disconnecting connection " that the first valve element is realized refers to that the cooling agent from the entrance of import 501 of valve body 500 can not cross the first valve element and the outlet 502 of valve body 500 can not be flowed to by inner flow passage." being connected by restriction " that second valve element is realized refers to that the second valve element can be crossed to flow to the outlet 502 of valve body 500 after the throttling by restriction from the cooling agent of the entrance of import 501 of valve body 500, and " the disconnecting connection " that the second valve element is realized refers to that the cooling agent from the entrance of import 501 of valve body 500 can not cross the second valve element and the outlet 502 of valve body 500 can not be flowed to by restriction 505.
So, by the control to the first valve element and the second valve element, expansion switch valve of the invention can at least to realize three kinds of states from the cooling agent that import 501 enters.That is, 1) cut-off state；2) the direct connected state of the first valve element 503 is crossed；And 3) cross the throttling mode of communicating of the second valve element 504.
Wherein, the liquid refrigerant of HTHP is again after the throttling of restriction 505, the vaporific hydraulic pressure refrigerant of low-temp low-pressure can be turned into, it can be created conditions for the evaporation of refrigerant, i.e. the cross-sectional area of restriction 505 is less than the cross-sectional area of outlet 504, and by controlling the second valve element, the aperture size of restriction 505 can be adjusted, with flow of the controlling stream through restriction 505, prevent because refrigerant it is very few caused by freeze deficiency, and prevent from causing compressor generation liquid hit phenomenon because refrigerant is excessive.That is, the cooperation of the second valve element 504 and valve body 500 can make it that expanding switch valve has the function of expansion valve.
So, by installing the first valve element 503 and the second valve element 504 on the inner flow passage of same valve body 500, to realize the break-make control of import 501 and outlet 502 and/or throttling control function, it is simple in construction, it is readily produced and installs, and when expansion switch valve provided by the invention is applied to heat pump, the refrigerant charge of whole heat pump can be reduced, cost is reduced, simplifies pipeline connection, the more conducively oil return of heat pump.
