A container weld seam leak detection device

Abstract

The invention relates to a container welding seam leakage detecting device, which effectively solves the problem of welding seam air leakage detection inconvenience. The container welding seam leakagedetecting device has the technical scheme that the container welding seam leakage detecting device comprises an electric ascending and descending platform, wherein a vertical first rotating shaft isarranged on the platform; a flat plate is arranged on the first rotating shaft; the flat plate is provided with a vertical lead screw; a second motor for driving the lead screw is fixed on the flat plate; a telescopic rod is arranged on the lead screw; a framework is arranged at the right end of the telescopic rod; a second rotating shaft is arranged on the framework; a turntable is fixed on the second rotating shaft; a plurality of first through holes are uniformly distributed in the turntable; a cover cap is arranged outside the first through holes; a fixing disc is sheathed on the second rotating shaft; a plurality of second through holes corresponding to the first through holes are formed in the fixing disc; a branch pipe is communicated with the through hole positioned the uppermost part in the plurality of second through holes; the framework is provided with a plurality of horizontal friction wheels positioned under the turntable; the friction wheels rotate and can drive the turntable to rotate through the second rotating shaft, so that the first through holes sequentially correspond to the branch pipes. The speed is accelerated; the accuracy is improved.

Description

technical field [0001] The invention relates to the field of pressure vessel detection, in particular to a container weld seam leakage detection device. Background technique [0002] The leak test can only be carried out after the container has passed the pressure test. The leak test includes air tightness test, ammonia leak test, halogen leak test and helium leak test. If the toxicity of the medium is relatively high and no leakage or penetration is allowed, use ammonia, halogen or helium, and the details shall be carried out by the manufacturer in accordance with the regulations in the design documents. However, there are certain difficulties in actual operation such as helium leak detection test. [0003] The detection standards of the helium positive pressure method mainly include "Helium Mass Spectrometry Positive Pressure Leak Detection Method" (QJ3089-1999), "Pressure Vessel Weld Seam Helium Mass Spectrometry Sniffer Cover Leak Test Method" (QJ2862-1996). [0004] W...
