The specific embodiment
Referring to Fig. 1, air-conditioner is made up of compressor 1, cross valve 2, outdoor heat exchanger 3, indoor heat exchanger 4, choke valve 5.See Fig. 5; Choke valve 5 is made up of valve seat 10, valve pocket 11 and spool (external screw thread spool 6, sliding valve core 7); The passage that valve seat is provided with between first valve port 21, second valve port, 22, the first valve ports and second valve port that connects the air conditioner refrigerating pipeline respectively is a valve pocket 11, is provided with internal thread segment in the valve pocket; In internal thread segment, be connected with external screw thread spool 6, be equipped with the throttling duct on external screw thread spool and the sliding valve core.
Referring to Fig. 2-3, external screw thread spool 6 has external thread part 61, and the external screw thread spool is provided with throttling duct 62, and an end of spool is provided with chamfering 66, and the other end of external screw thread spool 6 is provided with groove 63, is provided with sealing ring 64 in the groove 63, sealing ring 64 and valve pocket interference fit.Be provided with the hexagonal platform 65 that caves in the groove ends of external screw thread spool.
Referring to Fig. 4, sliding valve core 7 slides in the slideway 12 of valve pocket, is provided with throttling duct 71 in the sliding valve core 7, evenly is provided with four sliding ribs 72 on the excircle of sliding valve core.Sliding rib slides in slideway, makes the excircle of sliding valve core 7 and sliding chamber 12,72 at sliding rib form sliding rib runner.The end of sliding valve core 7 is provided with the sealing awl 73 of taper.
Referring to Fig. 5, slideway 12 is located at the top of valve pocket, and the bottom of slideway 12 is slideway frustums of a back taper.Sealing awl 73 is suitable with the slideway frustum in the slideway, when sealing awl 73 compresses the slideway frustum, forms sealing between the two.Be provided with internal thread segment in the valve pocket below slideway 12; External screw thread spool 6 is threaded in this valve pocket section; The bottom of the valve pocket of internal thread segment is provided with the valve pocket awl of back taper; The chamfering 66 of external screw thread spool 6 is bored the suitable sealing that reaches with the valve pocket in the valve pocket, and cold-producing medium is only flow through from the throttling duct of the spool of flowing through through the external screw thread spool time.Be provided with screen modules 14 and Non-return ring 13 in first valve port 21.On valve seat, also be provided with the 3rd valve port 23.Be provided with in the 3rd valve port by spool 15, the three valve port places and be provided with removable sealing shroud 16.
When air conditioner heat-production was worked, compressor 1 was discharged to cross valve 2 with the cold-producing medium of HTHP, flows to indoor heat exchanger 4 through cross valve; The heat release in indoor heat exchanger 4 of the gaseous refrigerant of HTHP is condensed into liquid refrigerant, and flows to choke valve 5, referring to Fig. 5; Cold-producing medium is after screen modules 14, and the cold-producing medium of cleaning gets into sliding chamber 12, promotes sliding valve core 7 and moves downward; Make the chamfering of sliding valve core 7 be close on the slideway frustum, make sliding chamber 12 be closed condition, cold-producing medium gets into the below of valve pocket through the throttling duct 71 of sliding valve core 7; After the throttling duct throttling of external screw thread spool 6; Leave choke valve 5 and inlet chamber external heat exchanger 3, get back to compressor 1 behind the gaseous state that flashes to low-temp low-pressure that in outdoor heat exchanger 3, absorbs heat, heat circulation again.The diameter of the throttle orifice of external screw thread spool 6 and length according to the required flow precise design of cooling condition with process, guarantee that the cold-producing medium pass through reaches the flow of specified refrigeration, realizes the specified refrigeration of heat pump air conditioner system.
When refrigeration work; Compressor 1 is discharged to cross valve 2 with the cold-producing medium of HTHP, flows to outdoor heat exchanger 3 through cross valve, and cold-producing medium release heat in outdoor heat exchanger is condensed into liquid refrigerant; And flow to choke valve 5; To indoor heat exchanger 4, flow to cross valve through choke valve again, get back in the compressor.Referring to Fig. 6; When cold-producing medium gets into choke valve 5 because that external screw thread spool 6 outsides and valve seat are able to inner chamber is airtight, so cold-producing medium through the throttling duct throttling of external screw thread spool 6 after in the slideway 12 of entering valve pocket; Cold-producing medium promotes sliding valve core 7 and moves upward; The Non-return ring 13 that the sliding rib 72 of the periphery of sliding valve core 7 receives on the valve pocket is spacing, and cold-producing medium filters the back through screen modules and flows out from first valve port through by bypass path that forms between the adjacent sliding rib and throttling duct 71.
