Specific embodiment
With reference to the accompanying drawings and examples the present invention is further described.
Referring to Fig. 1,2,3 and Fig. 4, self-operated three-way reversing valve proposed by the present invention include valve body 1, valve gap 2, valve element 3,
Spring 4, evaporimeter adapter 5, condenser adapter 6, compressor air-discharging adapter 7, sealing ring 8；The dislocation arrangement on valve body 1
Perpendicular to the evaporimeter adapter 5 and condenser adapter 6 of valve axis, and evaporimeter adapter axial line and condenser adapter axial line
The distance between L1Should be greater than the inside radius of evaporimeter adapter 5 and the inside radius sum of condenser adapter 6；Compressor air-discharging is taken over
7 are arranged on valve gap 2, and up big and down small shoulder hole is provided with valve body, and the internal diameter of hole 9 is outer with the valve element 3 on shoulder hole
Edge sliding fit, compression spring 4 is arranged between valve element bottom and the bottom of shoulder hole lower opening 10；The bottom surface in hole 9 is away from steaming on shoulder hole
Send out the axial line of device adapter 5 apart from L2Should be greater than the inside radius of evaporimeter adapter 5.With being threadedly coupled between valve gap 2 and valve body 1,
To prevent cold-producing medium from leaking outside, sealed using O shapes rubber seal 8 on the sealing surface between valve gap 2 and valve body 1；Valve element 3
Axially reciprocating can be made in valve body with the deformation of spring 4.
For ease of stably installing compression spring 4 under valve element 3, therefore valve element 3 is made into " convex " shape structure, compression spring 4
One end be placed on the shoulder of " convex " word structure.It is anti-when heat pipe runs kind of refrigeration cycle with steam compressed compound-refrigerating air-conditioner set
Only compressor air-discharging Jing evaporimeters adapter 5 is leak into compressor suction duct, the present invention hole 9 and shoulder hole lower opening 10 on shoulder hole
The cannelure 11 that external diameter is more than the diameter of shoulder hole lower opening 10 equal to or less than the diameter of hole 9, internal diameter on shoulder hole is opened up on interface,
The shoulder of valve element 3 is in close contact on the sealing surface constituted in cannelure 11 and shoulder hole lower opening 10；To prevent unit from following naturally
Cold-producing medium is entered in compressor along compressor air-discharging adapter 7 during ring, arranges external diameter in the bottom of valve gap 2 straight less than hole 9 on shoulder hole
Footpath, the internal diameter annular boss 12 suitable with the internal diameter of compressor air-discharging adapter 7, " convex " the word top surface of valve element 3 is in close contact in ring
On shape boss 12.
In technical scheme, in order to easy to assembly, can be by evaporimeter adapter 5 and condenser adapter 6 and the structure of valve body 1
Integrated valve component (see Fig. 2), it is also possible to by compressor air-discharging adapter 7 be integrally formed with valve gap 2 formula bonnet assemblies (see
Fig. 3)；Compression spring 4, valve element 3 are loaded in integral valve body component again, after sealing ring 8 is put into, by integral type valve gap
Component is screwed in integral valve body component, constitutes self-operated three-way reversing valve.
In the heat pipe shown in Fig. 4 with steam compressed compound-refrigerating air-conditioner set, when the outdoor temperature is lower than the indoor temperature, refrigeration pressure
Contracting machine 13 quits work, magnetic valve 16 is opened, and unit enters Natural Circulation, and the valve element 3 of self-operated three-way reversing valve is in valve body 1
Position as shown in Figure 1 and Figure 4.Compression spring 4 extends under elastic force effect, promotes valve element 3 along shoulder hole on the internal face in hole 9
Move, until the tight of valve element 3 is contacted on the annular boss 12 of the bottom of valve gap 2 so that evaporimeter adapter 5 and condenser adapter 6
Conducting.Now, the evaporimeter adapter 5, shoulder hole of the gaseous refrigerant Jing self-operated three-way reversing valves for evaporating from evaporimeter 14
Hole 9, condenser adapter 6 in lower opening 10, shoulder hole enters condenser 15, the condensed Returning evaporimeter 14 of liquid Jing magnetic valves 16
In, the Natural Circulation temperature-fall period of cold-producing medium is completed, indoor heat is transferred to by the lower outdoor of temperature by separate heat pipe
In environment.
When outdoor temperature is raised, when Natural Circulation can not meet cooling and require, refrigeration compressor 13 starts, magnetic valve 16 is closed
Close, unit enters kind of refrigeration cycle, the position of the valve element 3 of self-operated three-way reversing valve in valve body 1 is as shown in Figure 5.Refrigeration pressure
Contracting machine 13 from evaporimeter 14 air-breathing supercharging after enter compressor air-discharging adapter 7, now valve element 3 in the presence of high pressure gas,
The elastic force for overcoming compression spring 4 is moved down, and until being close to hole 9 and the interface of shoulder hole lower opening 10 on shoulder hole, is prevented high
Pressure gas is entered in evaporimeter adapter 5 so that compressor air-discharging adapter 7 is turned on condenser adapter 6.Now, from evaporimeter
The compressor air-discharging of the gaseous refrigerant Jing compressors 13, self-operated three-way reversing valve for absorbing heat in room in 14 and evaporating connects
Hole 9, condenser adapter 6 on pipe 7, shoulder hole enters condenser 15, the condensed Returning evaporimeter of liquid warp knuckle stream device 17
In 14, kind of refrigeration cycle temperature-fall period is completed, the heat in room is transferred in outdoor environment by steam compression type refrigerating.
When outdoor temperature is reduced to below indoor temperature, magnetic valve 16 is again turned on, and refrigeration compressor 13 is out of service, makes
Unit return to the nature circulation again.Now, compression spring 4 extends under elastic force effect, promotes the hole 9 along shoulder hole of valve element 3
On internal face move, until the tight of valve element 3 contact on the annular boss 12 of the bottom of valve gap 2 so that evaporimeter adapter 5 and
Condenser adapter 6 is turned on.The evaporimeter adapter 5 of the gaseous refrigerant Jing self-operated three-way reversing valves evaporated from evaporimeter 14,
Hole 9, condenser adapter 6 in shoulder hole lower opening 10, shoulder hole enters condenser 15, and condensed liquid Jing magnetic valves 16 are returned
In returning evaporimeter 14, the Natural Circulation temperature-fall period of cold-producing medium is completed.
So move in circles, open, shut down product with refrigeration compressor itself in steam compressed compound-refrigerating air-conditioner set using heat pipe
Raw pressure reduction change realizes automatic reverse of the self-operated three-way reversing valve without additional power with the elastic force of compression spring.
