  • Leakage detecting instrument
    Publication number: 20020178794
    Abstract: A leakage detecting instrument includes a connecting device (1) and an air-inlet device (2) combined with the connecting device (1). The connecting device (1) has a cap (10) adapted to be firmly secured on an inlet tube (31) of a water tank (30) and a screw rod (13) rotably penetrates the cap (10). The screw rod (13) supportably extends between the cap (10) and the inlet tube (31) to provide resistance to an internal pressure of the water tank (30) when air is compressed into the water tank to detect leakage.
