Abstract
Disclosed is a gas tightness test bench which comprises a rack, a workpiece clamping tool, a water tank lifting platform, and a pressure-increasing device. When the gas tightness test bench is in use, the pressure-increasing device generates high-pressure air which is connected to a valve clamped on the workpiece clamping tool. The water tank lifting platform can lift a water tank, and the valve is immersed into the water tank, so as to achieve the purpose of testing the tightness of the valve. The gas tightness test bench is convenient to operate and good in application effect.
