Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof valve detection, in particular to a device for detecting liquid leakage of an explosion-proof valve. Background Technique

[0002] Explosion-proof valves are widely used in many fields such as petrochemical industry, machinery manufacturing, energy and power. As a key safety protection device, its sealing performance and reliability directly affect the overall safety of the system. However, during actual operation, due to reasons such as medium corrosion, pressure fluctuations, and material aging, the explosion-proof valve may experience liquid leakage. This not only causes waste of resources but may also trigger safety accidents, pollute the environment, and even threaten the lives of personnel. Therefore, it is of great significance to develop an efficient and accurate device for detecting liquid leakage of explosion-proof valves.

[0003] A device for detecting liquid leakage of a battery explosion-proof valve with the reference publication number of CN219142125U includes a chassis, a mobile conveying mechanism, a handling mechanism, and a camera detection mechanism. The mobile conveying mechanism is installed on the chassis. The mobile conveying mechanism is provided with a sliding platform. The handling mechanism is installed on the sliding platform. The top of the handling mechanism is provided with a clamping part, and a battery is clamped on the clamping part. Above the battery clamped by the handling mechanism along the sliding direction of the sliding platform, a camera detection mechanism is installed. The bottom of the support plate of the handling mechanism is connected to the sliding platform, and the top of the support plate is connected to a lifting cylinder. A motor is connected to the side sliding table of the lifting cylinder, and the output shaft of the motor is connected to the bottom of a rotating seat. A sliding table cylinder is connected to the rotating seat. Two sliding tables on the top of the sliding table cylinder are both provided with clamping pieces. This device scans the battery on the handling mechanism with lifting and rotating functions through a camera, realizing a comprehensive detection of liquid leakage of the battery explosion-proof valve and improving the detection accuracy. According to the above, although this device can be well applied, it usually only relies on a camera to detect whether the explosion-proof valve leaks liquid, making the detection method of this device relatively single. Because it is not convenient to detect liquid leakage of the explosion-proof valve in multiple ways, the detection accuracy of this device is still difficult to reach the established expectation and needs to be improved.
