Description

Technical Field

[0001] The utility model relates to the technical field of breathing valve detection equipment, in particular to a breathing valve detection equipment for a petroleum storage tank. Background Art

[0002] The oil tank breathing valve detection equipment is a special equipment used to detect the performance and safety of the breathing valve of the oil tank. During the storage and transportation of oil in the oil tank, the pressure in the tank will change due to temperature changes and oil evaporation. In order to ensure the pressure balance in the tank and avoid deformation or explosion of the tank body, a breathing valve needs to be installed. The breathing valve is an important part of the oil tank, and its performance is directly related to the stability of the pressure in the tank and the safety of the tank body. The oil tank breathing valve detection equipment determines whether the breathing valve is working normally by detecting the opening pressure, closing pressure, sealing performance and other indicators of the breathing valve. The equipment generally includes pressure sensors, data acquisition devices, computers and other parts, which can monitor and record the working status of the breathing valve in real time, ensure that the breathing valve works within the normal range, prevent abnormal pressure in the tank caused by breathing valve failure, and ensure the safe operation of the oil tank. The oil tank breathing valve detection equipment is an important guarantee for the safe operation of the oil tank, and is of great significance to preventing accidents such as oil leakage, fire, and explosion.

[0003] First, traditional testing equipment uses flanges to connect the testing equipment and the breathing valve, which is slow to install and inefficient. Second, traditional testing equipment directly connects the air pump to the breathing valve, which will cause the connection between the breathing valve and the tank to loosen, affecting its use.
