Referring to the operation of the present invention configured as described above is as follows.

First, for convenience, as shown in FIG. 1A, the first and second solenoid valves 15a and 15b are simultaneously turned on by the operation of the timer switch 14 to open “a” of the valve plate 13 and at the same time “c”. Is closed, and the pump 7 is operated by the driving of the motor 6 while the " b " is closed and the " d " is open, the solution 2 inside the first cylinder 19 It is discharged to the pressure tank 1 side through the suction and discharge tubes 16-"a" of the solution distribution section 10-the extension pipe 11-the pump 7-the solution supply pipe 5, The check valve 27a located at the inlet side of the first suction pipe 23 is opened, so that the liquid 18 flows into the first cylinder 19 through the first suction pipe 23, and at this time, Since the check valve 27b located at the outlet side of the first discharge pipe 25 is kept closed, the liquid 18 introduced into the first cylinder 19 is not discharged from the first cylinder.

At the same time, the solution 2 in the pressure tank 1 is transferred to the second cylinder 20 through the solution discharge pipe 9-"d" of the solution distribution section 10-the solution second suction and discharge pipe 17. In the process of pushing the valve body 21b to the right as it flows into the inside of the second cylinder 20, the liquid 18 begins to be compressed, and with the subsequent compression, the liquid 18 inside the second cylinder 20 After the liquid is compressed above the set pressure, the check valve 27d provided at the outlet side of the second discharge pipe 26 is opened, so that the liquid 18 inside the second cylinder 20 is discharged to the second discharge pipe 26. Is discharged to the outside through the check valve (27c) located at the inlet side of the second suction pipe 24 is maintained in the closed state, so that the liquid 18 through the second suction pipe 24 is the second cylinder It does not flow into the inside of.

In the above operation, the solution 2 inside the pressure tank 1 is provided with a check valve 8 on the solution supply pipe 5 even though a predetermined pressure is applied by the gas filled therein. The phenomenon of backflow to the 7) side is prevented.

Thereafter, when the first and second solenoid valves 15a and 15b are operated at the same time by driving the timer switch 14 and the first and second solenoid valves 15a and 15b are turned off together in contrast to FIG. 1a. Contrary to the above, "c" is opened at the same time as "a" of the valve plate 13 is closed, and "d" is closed at the same time as "b" is opened.

In this state, when the pump 7 is operated by the driving of the motor 6, the solution 2 in the pressure tank 1 becomes the "b" of the solution discharge pipe 9-the solution distribution part 10-the solution first. As the liquid 18 flows into the first cylinder 19 through the suction and discharge tubes 16 and pushes the valve body 21a to the right, the liquid 18 inside the first cylinder 19 starts to be compressed. After the liquid in the first cylinder 19 is compressed to a predetermined pressure or more by the subsequent compression, the check valve 27b provided at the outlet side of the first discharge pipe 25 is opened, so that the first cylinder 19 The liquid 18 in the interior of the discharge is discharged to the outside through the first discharge pipe 25, at this time the check valve (27a) located on the inlet side of the first suction pipe 23 is maintained in a closed state The liquid 18 is not introduced into the first cylinder through the first suction pipe 23.

At the same time, the solution 2 in the inside of the second cylinder 20 is the second suction of the solution by the pressure difference caused by the driving of the pump 7 and the discharge tube 17-"c" of the solution distribution part 10. -Extension pipe (11)-Pump (7)-The solution supply pipe (5) is discharged to the pressure tank (1) side, in this process the pressure difference occurs inside the second cylinder 20, so the second suction pipe (24) The check valve 27c located at the inlet side of the is opened.

As such, when the check valve 27c positioned at the inlet side of the second suction pipe 24 is opened, the liquid 18 flows into the second cylinder 20 through the second suction pipe 24. The check valve 27d positioned at the outlet side of the discharge tube 26 is kept closed, so that the liquid 18 introduced into the second cylinder 20 is not discharged from the second cylinder.

As described above, the liquid (condensate in the case of a boiler, refrigerant in the case of a turbo refrigerator) is sucked into the first and second cylinders 19 and 20 through the first and second suction pipes 23 and 24. The process of compressing and discharging at a predetermined pressure is repeatedly performed. The temperature of the solution 2 is circulated through the closed circuit of the solution 2 in the pressure tank 1 by the driving of the impeller pump 7. The rising phenomenon is emitted to the outside through the cooling fin (1a) formed on the outer surface of the pressure tank (1) to prevent the phenomenon that the solution (2) is overheated.

4A and 4B are schematic diagrams showing another embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along the line A-A of FIG. 4B, which is different from one embodiment of the present invention in terms of valve bodies 21a and 21b. ) Structure is different.

That is, in one embodiment, the valve body (21a) (21b) is a plate-like heat-resistant rubber for dividing the interior of the first and second cylinders (19, 20), but shown in another embodiment 4 and 5 In the valve body 21a (21b) is formed in the form of a tube, the inside of the extension tube 22 extending from the first, second suction, discharge tube 16, 17 of the solution extends to the inside of the tube and the extension tube In the phase, a plurality of through holes 22a are formed to circulate the solution.

Therefore, as shown in FIG. 4A, the first cylinder 19 is filled with the liquid 18, and the inside of the second cylinder 20 is filled with the solution 2. The second cylinder is provided through the second suction pipe 24. Referring to the process of compressing the liquid 18 in the interior of the first cylinder 19 to a predetermined pressure or more in the process of sucking the liquid 18 in the interior of the (20) as follows.

"C" is opened at the same time as "a" in 13) is closed and "d" is closed at the same time as "b" is opened.

In this state, when the pump 7 is operated by the driving of the motor 6, the solution 2 in the pressure tank 1 becomes the "b" of the solution discharge pipe 9-the solution distribution part 10-the solution first. Intake / discharge tube 16-The liquid 18 in the inside of the first cylinder 19 in the process of expanding the tube flows into the inside of the bag-shaped tube 21a through the through hole 22a of the extension tube 22. Starts to be compressed, and after the compression of the liquid inside the first cylinder 19 by the subsequent compression is over the set pressure, the check valve 27b provided at the outlet side of the first discharge pipe 25 is opened. The liquid 18 inside the cylinder 19 is discharged to the outside through the first discharge pipe 25, at which time the check valve 27a located at the inlet side of the first suction pipe 23 is closed. Since the liquid 18 is not introduced into the first cylinder through the first suction pipe 23.

At the same time, the solution 2 inside the tube 21b positioned in the second cylinder 20 is supplied with the through hole 22a-the solution of the second suction of the extension tube 22 due to the pressure difference caused by the driving of the pump 7. The discharge tube 17 is discharged to the pressure tank 1 through the "c"-extension tube 11-pump 7-solution supply tube 5 of the solution distribution section 10, and in this process, the second cylinder Since a pressure difference is generated in the inside of the 20, the check valve 27b located at the inlet side of the second suction pipe 24 is opened.

As such, when the check valve 27b positioned at the inlet side of the second suction pipe 24 is opened, the liquid 18 flows into the second cylinder 20 through the second suction pipe 24. The check valve 27d positioned at the outlet side of the discharge tube 26 is kept closed so that the liquid 18 introduced into the second cylinder 20 is not discharged from the second cylinder.

As described above, according to the present invention, the liquid is sucked into the first and second cylinders and compressed and discharged according to the contraction and relaxation of the valve body in the separated first and second cylinders, thereby automatically discharging the liquid without frequent failures of components. It is possible to suck and discharge, thereby greatly improving the reliability of the product.

In addition, it is possible to save foreign currency due to the substitution effect of expensive imported goods.
