Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel leakage detection, in particular to a pressure vessel leakage detection mechanism. Background Art

[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels are divided into reaction vessels, heat transfer vessels, separation vessels and storage and transportation vessels according to their use. Pressure vessels are mainly used to complete the physical and chemical reactions of working media, which are called reaction vessels. Leakage and explosion may occur during use. The power generated by leakage and explosion is very strong and can cause serious consequences. Therefore, pressure vessels are specified as special equipment, and there are strict requirements for their production and use.

[0003] For example, a pressure vessel leakage detection structure is disclosed in a Chinese patent (CN219714637U), which belongs to the technical field of pressure vessel leakage detection devices, and includes a base, a bracket is fixed on one side of the upper end of the base, a turntable 1 is installed in the base, and a motor is connected to the bottom end of the turntable 1. The utility model designs a detection mechanism composed of a film pressure sensor, a turntable 1, a motor, a turntable 2, a grid plate, and a pressure plate of an electric push rod. During the detection process, the electric push rod fixes the pressure vessel between the turntable 1 and the pressure plate through the pressure plate, and the motor drives the pressure vessel to rotate through the turntable 1 and the turntable 2. When there is a leak in the pressure vessel, the leaked gas will act on the film pressure sensor due to its impact force. The detection value of the film pressure sensor can be used to determine whether there is a leak. Compared with the method of observing water bubbles, this method not only has high detection accuracy and low error, but also has a simple detection process and a small workload.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for finding the specific leakage location, because it takes a certain amount of time for the gas to be transmitted to the film pressure sensor after the leakage, and the motor is still driving the pressure vessel to rotate at this time, so the detection result of the film pressure sensor has a lag phenomenon. At the same time, because the film pressure sensor can only determine whether the pressure vessel is leaking, the specific leakage location is difficult to find. Based on this, a pressure vessel leakage detection mechanism is proposed. Utility Model Content
