Abstract

PURPOSE: To ensure a simple and assured sealing for the test liquid of the center hole by attaching removably the air pipe head to the sealing valve stuck to the sealing balloon.
CONSTITUTION: The head part 5 of the air pipe 6 is connected to the cap 13 of the sealing valve 4, and then the balloon 3 is inserted into the center hole 1a of the shaft 1. Then the valve 8 is opened to send the air via the tube 6, and thus the balloon 3 fills out to seal up the hole 1a. Then the operation tube 7 is turned by 90° after closing the valve 8 to detach the stopper 5a from the groove 13a. Under these conditions, the tube 6 is drawn out of the hole 1, and thus the valve 11 is pressed by the spring 12. As a result, the air in the balloon 3 does not leak out, and the coating test liquid is blocked by the balloon 3. In such way, a simple and assured sealing is secured for test liquid of the center hole.
