Claims

[Scope of Claim for Utility Model Registration] A water tank that stores water up to a predetermined water level, and is arranged so that air leaking from the valve under test is introduced into the water of the water tank, and the presence or absence of leaking air can be confirmed by the generation of air bubbles. A first air conduit, one end of which is open to allow leakage air to escape to the outside if necessary; when measuring the amount of leakage air;
A second air conduit is placed in front of the open end of the second air conduit, which is arranged so that the amount of leaked air can be introduced into the water tank from the valve under test, and the release of leaked air from the open end is stopped for a certain period of time. An open/close valve with a timer that automatically measures the amount of leaked air over a certain period of time, and communicates with the bottom of the tank until the water reaches a specified level. A water conduit which is a communication pipe arranged to collect water and is used to send water pushed out from the bottom of the water tank by the pressure of the leaked air introduced into the water tank to the measuring container described below when measuring the amount of leaked air; and A valve leakage measuring device consisting of a measuring container for collecting and measuring water from an aquarium.
