[0004] The water immersion detection method needs to use a large-sized reservoir and a heavy-duty transport device, which has defects such as bulky, high cost, and poor operability. At the same time, the accuracy of water detection is not high, and the leakage situation cannot be directly reflected by the detection data; the direct pressure pointer The interpretation method is susceptible to pressure fluctuations caused by the influence of the surrounding environment; when a large leak occurs, the pressure in the interior of the cylindrical container quickly reaches the same pressure as the pressure in the sealed chamber, resulting in the constant reading of the pressure gauge, resulting in wrong judgments

The invention provides a cylindrical container door air tightness detection tool, which comprises a sliding portion, a fixing portion, a lead screw and a detection device. The detection device is disposed in the fixing portion. The fixing portion comprises a front fixing portion and a rear fixing portion. End faces of the sliding portion and the front fixing portion penetrate into the lead screw. The sliding portion is connected fixedly with a nut. A side bearing is mounted between the front fixing portion and the lead screw. The outer end face of the sliding portion is provided circumferentially with a groove, in which a face end rubber gasket is fixed. The outer side wall of the front fixing portion is provided circumferentially with a groove, in which an extrusion rubber gasket is disposed. A plurality of detection interfaces are disposed in the portion, located outside the face end rubber gasket, of the sliding portion. The tool has the advantages of light volume, low cost, simple operation, high work efficiency, reliable detection result and the like, is used for detecting the air tightness of a door of a cylindrical container, and can effectively ensure the security performance of the sealing of the cylindrical container.
Description
technical field [0001] The invention belongs to the technical field of air tightness detection, in particular to an air tightness detection tool for the door of a cylindrical container. Background technique [0002] Cylindrical containers are used in a wide range of applications as energy storage, buffering, voltage stabilization, and escape and refuge devices. The tank body is usually made of monolithic processing or welding, and it is not a place where leakage often occurs; the joint between the tank body and the door is generally sealed by an apron, which is often caused by factors such as aging, wear, or structural design defects of the apron. The tank body and the door are not tightly sealed, resulting in leakage, which brings serious safety hazards to the normal use of the container. [0003] It is an important measure to eliminate the above safety hazards to carry out the air tightness test on the joint between the tank body and the door of the cylindrical container....
