Abstract

The invention discloses an inner container leakage detection method. The inner container leakage detection method comprises steps that nitrogen and hydrogen gas is injected into an inner container, and hydrogen detection is conducted on an annular weld joint, a linear weld joint, a water inlet and outlet pipe weld joint and an installation pipe opening weld joint on the inner container through a hydrogen detector. The method is advantaged in that automatic leakage detection of the inner container is achieved, labor cost and labor intensity of workers are reduced, and leakage detection efficiency and precision are improved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a leak detection method for an inner container. Background technique [0002] At present, water heaters are commonly used electrical appliances in people's daily life. The inner tank in the water heater is processed by welding (generally including circular welds and linear welds), and the inner tank is welded with water inlet and outlet pipes (water inlet and outlet pipes). Water pipe), at the same time, in order to install the electric heating tube and magnesium rod, the inner tank is welded with a corresponding installation nozzle to install the electric heating tube and magnesium rod. Therefore, after the inner tank is assembled, it is necessary to perform leak detection on the weld seam of the inner tank and related assembly parts. In the prior art, the leak detection method of the water heater liner is as follows: seal the assembled liner and fill it with high-pressure gas, then p...
