Abstract
A leak detection device and method for use in testing a wall with selective gas/liquid permeability. The wall is sealed inside a containment including an injection chamber and a test chamber. The injection chamber is in communication with an injection and pressurization source and the test chamber is in communication with a vacuum production device. A vaporized liquid detector is in communication with the test chamber operable to detect and/or measure a parameter related to a quantity of liquid vapor or a variation in the quantity of liquid vapor which is indicative of a leak condition through the wall.

A leak detection device for use with a wall having gas/liquid permeability, the leak detection device comprising:
- a test liquid circuit including a test liquid;
- an injection and pressurization device in communication with the test liquid circuit;
- a containment in selective fluid communication with the test liquid circuit, the wall sealingly positioned in the containment;
- an injection chamber positioned within the containment, the injection chamber in selective communication with the injection and pressurization device, the injection and pressurization device operable to selectively apply a liquid pressure to the injection chamber;
- a test chamber positioned within the containment;
- a vacuum production device in selective communication with the test chamber, the vacuum production device operable to selectively apply a vacuum pressure to the test chamber;
- and
- a vaporized liquid detector in communication with the test chamber, the vaporized liquid detector operable to at least one of detect or measure at least one parameter related to a quantity of liquid vapor or a variation of the quantity of liquid vapor in the test chamber, or a liquid vapor flow, the parameter indicative of a leak condition through the wall.
The leak detection device according to 2, wherein the containment further comprises:
- a sealed channel in communication with the injection chamber and the test liquid circuit, said test liquid supply circuit further comprising:
- a liquid supply reservoir;
- and
- a filter positioned between said liquid supply reservoir and said injection chamber.
The leak detection device according to 1, wherein the containment further comprises a sealed channel in communication with the injection chamber and the test liquid circuit, said test liquid supply circuit further comprising a liquid supply reservoir.
