Abstract
The utility model discloses a helium detection tool for internal leakage detection of a cooling pipe, relates to the technical field of internal leakage detection of the cooling pipe, and solves the technical problem that internal leakage detection of a water cooling pipe of which two ends are integrally welded is relatively difficult. Comprising a bottom plate and a supporting piece installed on the bottom plate and used for supporting the water-cooled pipe, the supporting piece comprises a water nozzle fixing clamp and a supporting block, the water nozzle fixing clamp and the supporting block are distributed at the top of the bottom plate in the length direction of the bottom plate, and the supporting block is used for lifting and limiting the tail end of the water-cooled pipe; the water nozzle fixing clamp is used for limiting a cooling pipe water nozzle at the end of a water cooling pipe, a pressing block is correspondingly arranged in the direction of one side of the water nozzle fixing clamp, and a driving piece used for controlling the pressing block to be close to the water nozzle fixing clamp is installed on the bottom plate. According to the utility model, by comparing the time difference of helium flowing to the inner leakage part and the time difference of helium flowing to the U-shaped loop, whether inner leakage occurs at the welding part of the cooling pipe water nozzle and the water cooling pipe can be conveniently detected.
