Embodiment:
See that Fig. 1 to Fig. 9 shows: the sliding valve style self-operated three-way reversing valve of the utility model includes that valve body 10, compressor take over 21, vaporizer takes over 22, condenser takes over 23, slide block 30, connecting rod 40, first piston 51, second piston 52, spring assembly 60, high pressure capillary 71 and low pressure capillary tube 72; Wherein, The two ends of valve body 10 are respectively equipped with valve gap 11 and spring end cap 12, and compressor adapter 21, vaporizer adapter 22 and condenser are taken over 23 and be welded on the valve body 10, and slide block 30 is fixing through connecting rod 40; The first piston 51 and second piston 52 are positioned at connecting rod 40 two ends and valve body 10 inside are divided into three chambers; Spring assembly 60 is between second piston 52 and spring end cap 12, and high pressure capillary 71 is communicated with the chamber between compressor adapter 21 and end cap 11 and the first piston 51, and low pressure capillary tube 72 is communicated with the chamber between vaporizer adapter 22 and the spring end cap 12 and second piston 52; Compressor is taken over 21 and is arranged at slide block 30 tops; In the time of compressor start, inlet air flow is pressed to slide block 30, to reduce internal leakage.The sealing surface of slide block 30 is greater than the valve seat orifice area on the valve body 10, and behind compressor start, slide block 30 slides gradually, and the sealing surface of slide block 30 continues to slide and just can open the valve seat orifice on exhaust outlet of compressor and the valve body 10 after guaranteeing to close valve seat orifice fully.Certainly, the sealing surface of slide block 30 is equal to or slightly less than the area of valve seat orifice, also can realize the switching of three-way valve.
The utility model adopts compressor to take over (being compressor exhaust pipe) 21 air inlets, pushes down slide block 30 through air-flow, guarantees stability and reliability that three-way diverter valve switches, realizes effective switching of no additional power.
In heat pipe shown in Figure 3/both vapor compression compound-refrigerating air-conditioning unit, when outdoor temperature was lower than room temperature, refrigeration compressor 105 quit work; Solenoid valve 103 is opened; Unit gets into natural circulation, and pressure spring 61 extends under the elastic force effect, promotes the first piston 51 and second piston 52 and in valve body 10, moves to left; Closely contact on the end face of valve gap 12 bottoms until first piston 51 tops, make vaporizer adapter 22 take over 23 conductings with condenser; At this moment; From vaporizer 104, evaporate the gaseous refrigerant that and take over 23 entering condensers 101 through vaporizer adapter 22, slide block 30, condenser; Condensed liquid is in solenoid valve 103 Returning evaporimeters 104; Accomplish the natural circulation temperature-fall period of refrigeration agent, through separate heat pipe with indoor transfer of heat in the lower outdoor environment of temperature.
When outdoor temperature raise, natural circulation can not satisfy lowered the temperature when requiring, and refrigeration compressor 105 starts, and solenoid valve 103 cuts out, and unit gets into refrigeration cycle, and the first piston 51 and second position of piston 52 in valve body 10 are as shown in Figure 2.Refrigeration compressor 105 gets into compressor and takes over 21 after the air-breathing supercharging from vaporizer 104; The elastic force that this moment, first piston 51 and second piston 52 overcame pressure spring 61 under the effect of high pressure gas moves right; Contact up to spring seat 62 and spring spool 63; Stop high pressure gas to get into vaporizer and take in 22, make compressor adapter 21 take over 23 conductings with condenser.At this moment; From vaporizer 104, absorb heat in the room and evaporate the gaseous refrigerant that through refrigeration compressor 105, compressor take over 21, valve body 10, condenser take over 23 and get into condensers 101; Condensed liquid is in throttling arrangement 102 Returning evaporimeters 104; Accomplish the refrigeration cycle temperature-fall period, through steam compression type refrigeration with the transfer of heat in the room in outdoor environment.
When outdoor temperature is reduced to room temperature when following, solenoid valve 103 is opened once more, and refrigeration compressor 105 quits work, and makes unit return to the nature circulation again.At this moment; Pressure spring 61 extends under the elastic force effect; Promoting the first piston 51 and second piston 52 moves to left in valve body 10; Closely contact on the end face of valve gap 12 bottoms until first piston 51 tops, make vaporizer adapter 22 take over 23 conductings, from vaporizer 104, evaporate the gaseous refrigerant that and take over 23 entering condensers 101 through vaporizer adapter 22, slide block 30, condenser with condenser; Condensed liquid turns back in the vaporizer 104 through solenoid valve 103, accomplishes the natural circulation temperature-fall period of refrigeration agent.
So move in circles, utilize the pressure reduction that opens, shuts down generation of refrigeration compressor in heat pipe/both vapor compression compound-refrigerating air-conditioning unit 105 self to change and the elastic force of pressure spring 61 realizes that the sliding valve style self-operated three-way reversing valve does not have the automatic reverse of additional power.
The above is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
