Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1,2,3 and Fig. 4, the self-operated three-way reversing valve that the utility model proposes comprises that valve body 1, valve gap 2, spool 3, spring 4, vaporizer take over 5, condenser takes over 6, compressor air-discharging takes over 7, seal ring 8; On valve body 1 dislocation arrange perpendicular to the vaporizer of valve axis take over 5 and condenser take over 6, and vaporizer is taken over the distance L 1 that shaft axis and condenser take between the shaft axis and should be taken over 5 the inside radius and the inside radius sum of condenser adapter 6 greater than vaporizer; Compressor air-discharging is taken over 7 and is arranged on the valve gap 2, is provided with up big and down small shoulder hole in valve body, and the outer rim sliding fit of hole 9 internal diameters and described spool 3 on the shoulder hole, pressure spring 4 are arranged under spool bottom and the shoulder hole between 10 bottoms, hole; The distance L 2 that 5 shaft axiss are taken over apart from vaporizer in the bottom surface in hole 9 on the shoulder hole should be taken over 5 inside radius greater than vaporizer.With being threaded, leak outside between valve gap 2 and the valve body 1, on the sealing surface between valve gap 2 and the valve body 1, adopt 8 sealings of 0 shape rubber seal for preventing refrigeration agent; Spool 3 can be made axially reciprocating with the distortion of spring 4 in valve body.
For ease of at 3 times stable pressure springs 4 of installing of spool,, an end of pressure spring 4 is placed on the shoulder of " protruding " word structure so spool 3 is made " protruding " shape structure.Heat pipe and steam compressed compound-refrigerating air-conditioning unit running refrigerating circulation time, for preventing that compressor air-discharging is in compressor suction duct is bled in vaporizer adapter 5, the utility model is offered external diameter and is equal to or greater than hole 9 diameters on the shoulder hole, the internal diameter circular groove 11 greater than 10 diameters of hole under the shoulder hole on 10 interfaces of hole under hole on the shoulder hole 9 and shoulder hole, the shoulder of spool 3 is closely on the contact sealing surface that hole 10 constitutes under circular groove 11 and shoulder hole; Take over 7 along compressor air-discharging and enter in the compressor for preventing unit refrigeration agent when the natural circulation, valve gap 2 bottoms be provided with external diameter less than shoulder hole on hole 9 diameters, internal diameter and compressor air-discharging take over the suitable annular boss of 7 internal diameters 12, " protruding " word end face of spool 3 closely contact on annular boss 12.
In the technical solution of the utility model, for easy to assembly, vaporizer can be taken over 5 and condenser take over 6 and constitute integral type valve component (see figure 2) with valve body 1, also compressor air-discharging can be taken over 7 and constitute integral type valve gap assembly (see figure 3)s with valve gap 2; Again pressure spring 4, spool 3 are packed in the integral type valve component, after putting into seal ring 8, integral type valve gap assembly is screwed in the integral type valve component, constitute self-operated three-way reversing valve.
In heat pipe shown in Figure 4 and steam compressed compound-refrigerating air-conditioning unit, when outdoor temperature is lower than room temperature, refrigeration compressor 13 quits work, solenoid valve 16 is opened, and unit enters natural circulation, and the position of spool 3 in valve body 1 of self-operated three-way reversing valve as shown in Figure 1 and Figure 4.Pressure spring 4 extends under the elastic force effect, promotes spool 3 along moving on the internal face in hole on the shoulder hole 9, closely contacts on the annular boss 12 of valve gap 2 bottoms until spool 3 tops, makes vaporizer adapter 5 take over 6 conductings with condenser.At this moment, the gaseous refrigerant that from vaporizer 14, evaporates through the vaporizer of self-operated three-way reversing valve take over 5, under the shoulder hole on hole 10, the shoulder hole hole 9, condenser take over 6 and enter condenser 15, condensed liquid is in solenoid valve 16 Returning evaporimeters 14, finish the natural circulation temperature-fall period of refrigeration agent, by 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 13 starts, solenoid valve 16 cuts out, and unit enters refrigeration cycle, and the position of spool 3 in valve body 1 of self-operated three-way reversing valve as shown in Figure 5.Refrigeration compressor 13 enters compressor air-discharging and takes over 7 after the air-breathing supercharging from vaporizer 14, this moment, spool 3 was under the effect of high pressure gas, the elastic force that overcomes pressure spring 4 moves down, up to the interface of being close to hole 10 under hole on the shoulder hole 9 and the shoulder hole, stop high pressure gas to enter vaporizer and take in 5, make compressor air-discharging adapter 7 take over 6 conductings with condenser.At this moment, hole 9, condenser are taken over 6 and are entered condenser 15 on the compressed machine 13 of gaseous refrigerant that absorbs heat in the room and evaporate from vaporizer 14, the compressor air-discharging adapter 7 of self-operated three-way reversing valve, the shoulder hole, condensed liquid is in throttling arrangement 17 Returning evaporimeters 14, finish the refrigeration cycle temperature-fall period, by steam compression type refrigerating with the transfer of heat in the room in outdoor environment.
When outdoor temperature is reduced to room temperature when following, solenoid valve 16 is opened once more, and refrigeration compressor 13 is out of service, makes unit return to the nature circulation again.At this moment, pressure spring 4 extends under the elastic force effect, promotes spool 3 along moving on the internal face in hole on the shoulder hole 9, closely contacts on the annular boss 12 of valve gap 2 bottoms until spool 3 tops, makes vaporizer adapter 5 take over 6 conductings with condenser.The gaseous refrigerant that from vaporizer 14, evaporates through the vaporizer of self-operated three-way reversing valve take over 5, under the shoulder hole on hole 10, the shoulder hole hole 9, condenser take over 6 and enter condenser 15, condensed liquid is finished the natural circulation temperature-fall period of refrigeration agent in solenoid valve 16 Returning evaporimeters 14.
So move in circles, utilize the pressure reduction that opens, shuts down generation of refrigeration compressor self in heat pipe and the steam compressed compound-refrigerating air-conditioning unit to change and the elastic force of pressure spring realizes that self-operated three-way reversing valve does not have the automatic reverse of additional power.
