ABSTRACT:
A valve test apparatus, a solenoid valve test method and a venturi valve test method are provided. The valve test apparatus may include a gas supply unit, a solenoid valve holding unit, a first measurement unit, a venturi valve holding unit, a second measurement unit, a timer unit and/or a power supply unit. The solenoid valve holding unit may be connected to one end of the gas supply unit. The first measurement unit may be connected to the solenoid valve holding unit. The venturi valve holding unit, on which a venturi valve to be tested may be arranged. The venturi valve may be selectively connected to the solenoid valve holding unit together with the first measurement unit. The second measurement unit may be connected to the venturi valve. The timer unit may measure a time interval between when the solenoid valve is activated and when a measured value by the first measurement unit or second measurement unit is equivalent to a desired value.
