A tank safety accessory calibration device

Abstract

This utility model relates to the field of testing technology for safety accessories of storage tanks, and in particular to a calibration device for safety accessories of storage tanks. The device includes a calibration platform, a sealing detection cover, a vacuum suction gun, and a helium mass spectrometer. The top of the calibration platform is equipped with a sealing detection cover. In this utility model, helium gas is input into the cavity through the aforementioned calibration platform, sealing detection cover, vacuum suction gun, and helium mass spectrometer. The cavity is filled with helium gas through a jet nozzle, allowing the helium gas to be quickly and evenly distributed on the outside of the storage tank hydraulic safety valve. The vacuum suction gun is activated under negative pressure. If the storage tank hydraulic safety valve shell has a leakage area, the helium gas will enter the connecting sleeve, the vacuum suction gun, and the detection port of the helium mass spectrometer through the leakage area. The main body of the device facilitates the rapid and even distribution of the detection helium gas on the outside of the storage tank hydraulic safety valve, thereby improving the sealing detection efficiency of the storage tank hydraulic safety valve.
