The first wire holder 520 is formed with a bolt insertion hole into which the bolt can be inserted, and the inner circumferential surface of the bolt insertion hole is provided with a screw thread A screw groove can be formed. One end of the wire 510 passing through the first wire holder 520 is firmly fixed to the first wire holder 520 when the first coupling hole 540 and the first wire holder 520 are coupled to each other .

For example, the second coupling hole 550 may be formed in the second wire holder 510 in a direction perpendicular to the direction in which the wire 510 passes, with the other end of the wire 510 opposite to the one end of the wire 510 interposed therebetween, (Not shown). The second wire holder 530 may be formed with a bolt insertion hole into which the bolt can be inserted, and the inner circumferential surface of the bolt insertion hole may be provided with a screw thread A screw groove can be formed. The other end of the wire 510 passing through the second wire holder 530 is firmly fixed to the second wire holder 530 when the second coupling hole 550 and the second wire holder 530 are coupled to each other .

The adhered portion 560 may be configured such that the first chamber 100 and the second chamber 200 seal the first opening and the second opening of the first tube, respectively. In one example, the adhered portion 560 may include a fixed portion 562 and a moving portion 564. The fixing portion 562 may be disposed on the inner circumferential surface of any one of the first through hole 320 and the second through hole 420. The fixing portion 562 may have a thread on the outer circumferential surface thereof, A through hole 566 is formed.

The moving portion 564 has a fourth through hole 568 through which the wire 510 can pass and a thread groove corresponding to the thread of the fixing portion 562 is formed on the inner peripheral surface of the fourth through hole 568 And the moving part 564 is movable along the thread of the fixing part 562. [ That is, when the constant-angle portion 564 is rotated, it is possible to move along the thread of the fixed portion 562 according to the rotation direction.

For example, the wire 510 penetrates through the first wire holder 520, the second tube and the second wire holder 530 so that one end of the wire 510 penetrates through the first wire holder 520 The other end of the wire 510 passes through the second wire holder 530 and then the wire 510 is inserted into the first wire holder 520 through the first coupling hole 540 and the second coupling hole 550 And the second wire holder 530, respectively. When the moving part 564 is moved to be in close contact with any one of the first wire holder 520 and the second wire holder 530, the first clamp 300 is moved to the first opening side of the first tube The first chamber 100 can be pushed so that the first chamber 100 can seal the first opening of the first tube. Also, the second clamp 400 can push the second chamber 200 toward the second opening side of the first tube so that the second chamber 200 can close the second opening of the first tube.

The cleaning liquid supply passage 600 is connected to the second cleaning liquid supply port 310 and allows the cleaning liquid to be supplied to the second cleaning liquid supply port 310. The cleaning liquid discharge passage 700 is connected to the second cleaning liquid discharge port 410 and allows the cleaning liquid to be discharged from the second cleaning liquid discharge port 410. For example, a silicone hose made of a flexible material may be used as the cleaning liquid supply passage 600 and the cleaning liquid discharge passage 700.

The cleaning liquid container 800 can receive a cleaning liquid for cleaning foreign substances adhered to the inside of the condenser tube.

The cleaning liquid supply pump 900 can supply the cleaning liquid from the cleaning liquid accommodating portion 800 to the cleaning liquid supply path 600. A pump or the like which is generally used for supplying fluid may be used as the cleaning liquid supply pump 900. The rinse solution discharge port 700, the rinse solution receiving portion 800, the rinse solution supply pump 900, and the rinse solution supply passage 600 are connected to each other so that the rinse solution can communicate with each other.
