(10) pins of the J< 1 >, J< 2 >, J< 3 > is connected with one line of air discharging electromagnetic valves V< 1 >, V< 2 > to be connected in parallel with the power supply. The other line of the air discharging electromagnetic valves V< 1 >, V< 2 > is connected with (9) pins of the J< 2 >, J< 3 >. (3), (4) pins of the J< 1 >, and (8), (9) pins of the J< 1 > are respectively connected with (7), (6) pins of the J< 3 >, and (7), (6) pins of the J< 3 >. The utility model has the advantages of simple structure, compactness, and practicality. The utility model can regulate frequency for air feeding and air discharging for a vessel refrigerator in a stepless mode, and can flexibly regulate a duty ratio.
Description
The utility model relates to the distribution control device of vascular refrigerator.
Vascular refrigerator is simple in structure, and cold junction does not have vibration source, source of wear, and is reliable, and obtained breakthrough recent years on refrigeration performance, causes the common concern of cryogenic engineering circle.Compressor makes pulse tube refrigeration two kinds of development trends occur as " heart " of vascular refrigerator: a kind of is adapted valveless compressor, is operated under the high frequency about 15Hz, and the operating condition of simulation sterlin refrigerator is called the stirling-type vascular refrigerator; Another kind is that adapted has the valve compressor, and the operating condition of simulation G-M refrigeration machine is called G-M type vascular refrigerator.Existing result of study shows that low frequency, the high pressure ratio of G-M type vascular refrigerator, the characteristics of atm number make it be easier to obtain good refrigeration performance.And intake and exhaust frequency and dutycycle are the important parameters of vascular refrigerator, and the past people adopt rotary valve or variable-frequency control technique to come controlled frequency, and the former can't regulate once just installing, and the latter costs an arm and a leg, and be difficult to promote, and both all can't regulate dutycycle.
The purpose of this utility model provides a kind of step-less adjustment that realizes the inlet and outlet frequency of vascular refrigerator, and regulates the distribution control device of the vascular refrigerator of dutycycle neatly.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is an I type control circuit schematic diagram;
Fig. 2 is an II type control circuit schematic diagram;
Fig. 3 is an inlet and outlet magnetic valve working condition schematic diagram.
For realizing to intermitten and have two valves of time-delay to carry out freely controlling mutually that we have designed the compact and simple practical control system of a cover.In control system, we have only adopted three time relay (Solid-state Timer) H3BA that Japan OMRON is produced.H3BA has two groups of duplicate control ports, wherein one group be 1.-3. (often open), 1.-4. (normally closed), another group is
-9. (often open),
-8. (normally closed).
Owing to require periodically to move magnetic valve,, be used to provide enabling signal and the reset signal of other two H3BA so we determine that at first wherein a H3BA adopts the B mode of operation.Introduce the connection line of control system (two kinds of connected modes are arranged) below.
