Operation principle and the preferred embodiment of the present invention are described below
The critical piece of the whole device of the present invention is main valve body 1, and the internal middle of main valve body 1 has one by the
One piston 4-1, the second piston 4-2, guide rod 3 and the reversing unit of commutation passage 10 composition, reversing unit
Jointly surround with main valve body outer wall and define a piston chamber 2.Piston chamber 2 and First Heat Exchanger connecting tube 9
Permanent communication, the piston chamber 2 residing for guide rod communicates, and is used for connecting First Heat Exchanger connecting tube 9 and liquid cold dish
Tube inlet connecting tube 11.Piston chamber 2 while being first piston chamber 5-1, first piston chamber 5-1 is by first
Piston 4-1, the first end cap 6-1 and main valve body 1 outer wall surround formation jointly, change from second for impression
The pressure of the fluid of hot device connecting tube 12.The another side of piston chamber 2 is the second plunger shaft 5-2, the second piston
Chamber 5-2 is jointly surrounded formed by the second piston 4-2, the second end cap 6-2 and main valve body 1 outer wall, is used for experiencing
Pressure from the fluid of First Heat Exchanger connecting tube 9.Four connecting tubes and two elder generations are had around main valve body 1
Leading capillary tube, top is First Heat Exchanger connecting tube 9, and three connecting tubes of lower section are from left to right sequentially connected with
Throttling arrangement 8 (preferred electron expansion valve), the second heat exchanger connecting tube 13, liquid cooling coil entrance connecting tube
11, throttling arrangement 8 (preferred electron expansion valve) also has a pipe to be attached to liquid cooling coil outlet connecting pipe
12, connect first piston chamber 5-1 and the second heat exchanger connecting tube 12 is that the first bypass connecting pipe 7-1 is (excellent
Elect guide's capillary tube as), connect the second plunger shaft 5-2 and First Heat Exchanger connecting tube 9 is the second bypass
Connecting tube 7-2 (preferably guide's capillary tube).
Auto reversive principle is, when there is pressure reduction from the fluid of the first and second heat exchangers, and this pressure
Difference can be reflected in first piston chamber 5-1 and the second plunger shaft 5-2, when the pressure reduction of the two plunger shaft reaches
During the action pressure reduction of reversing unit, reversing unit can move towards that plunger shaft that pressure is relatively low, thus completes
Commutation.
The process of implementing is, when high pressure fluid is from First Heat Exchanger connecting tube 9, and major part high pressure
Fluid can enter piston chamber 2, and a small amount of high-pressure spray is known from experience from the second bypass connecting pipe 7-2 (preferably guide's hair
Tubule) enter into the second plunger shaft 5-2, cause the high pressure of the second plunger shaft 5-2, now the second plunger shaft
5-2 is high pressure and first piston chamber 5-1 is usual pressure, and therefore reversing unit can be to first piston chamber 5-1

11, then flow to the liquid cooling coil accessed, then flow back fluid cooling coil outlet connecting pipe 12, enter into throttling arrangement
8 (preferred electron expansion valves), after throttling arrangement 8 (preferred electron expansion valve) throttles into low-pressure fluid
Flow into piston chamber 2, then flow to First Heat Exchanger connecting tube 9.Major part lowpressure stream is known from experience from First Heat Exchanger
Connecting tube 9 flows out, and a small amount of high-pressure spray is known from experience from the second bypass connecting pipe 7-2 (preferably guide's capillary tube)
Enter into the second plunger shaft 5-2, cause the low pressure of the second plunger shaft 5-2.Now the second plunger shaft 5-2 is low
Pressure and first piston chamber 5-1 be still high pressure, therefore reversing unit still keeps original the most close second end cap 6-2
Invariant position.So far, the high pressure fluid whole automatic reverse when the second heat exchanger connecting tube 13
Process completes.
