The most of the present utility model operation principle and preferred embodiment are described below
The critical piece of the whole device of this utility model is main valve body 1, and the internal middle of main valve body 1 has one to be lived by first
Plug 4-1, the second piston 4-2, guide rod 3 and the reversing unit of commutation passage 10 composition, reversing unit wraps jointly with main valve body outer wall
Enclose 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,
For connecting First Heat Exchanger connecting tube 9 and liquid cooling coil entrance connecting tube 11.Piston chamber 2 while being first piston chamber 5-1,
First piston chamber 5-1 is jointly surrounded formed by first piston 4-1, the first end cap 6-1 and main valve body 1 outer wall, for impression from
The pressure of the fluid of the second heat exchanger connecting tube 12.The another side of piston chamber 2 is the second plunger shaft 5-2, the second plunger shaft 5-2 by
Second piston 4-2, the second end cap 6-2 and main valve body 1 outer wall surround formation jointly, for impression from First Heat Exchanger connecting tube
The pressure of the fluid of 9.Having four connecting tubes and two guide's capillary tubies around main valve body 1, top is First Heat Exchanger connecting tube
9, 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 pipe is attached to liquid cooling coil and goes out
Mouthful connecting tube 12, connect first piston chamber 5-1 and the second heat exchanger connecting tube 12 be the first bypass connecting pipe 7-1 (preferably
Guide's capillary tube), connect the second plunger shaft 5-2 and First Heat Exchanger connecting tube 9 be the second bypass connecting pipe 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, this pressure reduction can be anti-
Reflect on first piston chamber 5-1 and the second plunger shaft 5-2, when the pressure reduction of the two plunger shaft reaches the action pressure reduction of reversing unit
Time, 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, major part high-pressure spray know from experience into
Entering piston chamber 2, a small amount of high-pressure spray cognition enters into the second plunger shaft from the second bypass connecting pipe 7-2 (preferably guide's capillary tube)
5-2, causes the high pressure of the second plunger shaft 5-2, and now the second plunger shaft 5-2 is high pressure and first piston chamber 5-1 is usual pressure,
Therefore reversing unit can move to reach the position near the first end cap 6-1 to first piston chamber 5-1, and after moving into place, first changes
Hot device connecting tube 9 will connect with liquid cooling coil entrance connecting tube 11, and the second heat exchanger connecting tube 13 will be with throttling arrangement 8
(preferred electron expansion valve) connects.At this moment, the high-pressure fluid flowing to piston chamber 2 will flow to liquid cooling coil entrance connecting tube 11, then
Flowing to the liquid cooling coil accessed, then flow back fluid cooling coil outlet connecting pipe 12, (preferred electron expands to enter into throttling arrangement 8
Valve), after throttling arrangement 8 (preferred electron expansion valve) throttles into low-pressure fluid, flow to second through commutation passage 10 excessively and change
Hot device connecting tube.
When high pressure fluid is from the second heat exchanger connecting tube 13, major part high-pressure spray knows from experience entrance piston chamber 2, on a small quantity
High-pressure spray cognition enters into first piston chamber 5-1 from the first bypass connecting pipe 7-1 (preferably guide's capillary tube), causes first to live
The high pressure of plug chamber 5-1, now first piston chamber 5-1 is high pressure and the second plunger shaft 5-2 is usual pressure, therefore reversing unit meeting
Moving to reach the position near the second end cap 6-2 to the second plunger shaft 5-2, after moving into place, First Heat Exchanger connecting tube 9 will
Connecting with throttling arrangement 8 (preferred electron expansion valve), the second heat exchanger connecting tube 13 will be with liquid cooling coil entrance connecting tube 11
Connection.At this moment will flow to liquid cooling coil entrance connecting tube 11 by commutation passage 10 from the second heat exchanger connecting tube 13, 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 valve),
After throttling arrangement 8 (preferred electron expansion valve) throttles into low-pressure fluid, flow into piston chamber 2, then flow to First Heat Exchanger connection
Pipe 9.Major part lowpressure stream cognition flows out from First Heat Exchanger connecting tube 9, 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) enters into the second plunger shaft 5-2, causes the low pressure of the second plunger shaft 5-2.Now the second plunger shaft
5-2 be low pressure and first piston chamber 5-1 still for high pressure, therefore reversing unit still keeps the original position near the second end cap 6-2
Put constant.So far, the high pressure fluid whole automatic reverse process when the second heat exchanger connecting tube 13 completes.
