Description

Technical Field

[0001] The utility model relates to the technical field of breathing valves, in particular to a bearing device for online detection of breathing valves. Background Art

[0002] The petrochemical industry has extremely high safety requirements for storage tanks due to its special production environment. During the storage and transportation of the tank, the fluctuation of the internal pressure needs to be adjusted by the breathing valve to ensure the safe operation of the tank. The breathing valve can automatically open and release the pressure when the internal pressure of the tank exceeds the set value, or inhale air when the pressure is lower than the set value to maintain the pressure balance inside and outside the tank. In order to detect whether the function and performance of the breathing valve are normal, it is required to conduct annual inspections of the breathing valve regularly. Offline detection is costly and has high operational safety risks. The bottom valve is not allowed to appear between the breathing valve and the tank. It is necessary to design a breathing valve with online detection function.

[0003] There is a lack of online detection devices for breathing valves that support large size and heavy weight on the market. To ensure that the detection device has sufficient stability during quick lifting or separation, the existing detection devices may not provide sufficient stability during the lifting process, which increases the safety risks during the detection process. They cannot bear the weight of the breathing valve and the additional load that may be generated during the detection process. In addition, during the detection and maintenance process, the breathing valve needs to be lifted for inspection and operation. Based on the above problems, we propose a load-bearing device for online detection of breathing valves. Utility Model Content

[0028] Preferably, the driving member 102 comprises a rotating wheel 102a disposed outside the base 101a, and a handle 102b is disposed on the outer wall of the rotating wheel 102a.

[0029] Preferably, the transmission member 103 comprises a first reversing shell 103a disposed outside the rotating wheel 102a, a first rotating shaft 103b is disposed inside the first reversing shell 103a, a first bevel gear 103c is disposed at one end of the first rotating shaft 103b, and the other end is fixedly connected to the rotating wheel 102a.

[0030] Preferably, a second bevel gear 103d is meshed with an outer wall of the first bevel gear 103c, and a second rotating shaft 103e penetrates the interior of the second bevel gear 103d.

[0032] Among them, the plurality of threaded holes 101c are preferably four, distributed at 90°, the base 101a is provided with threaded holes corresponding to the plurality of threaded holes 101c, and the breathing valve can be further sealed by a screw connection; the blind plate 101d is an open hole plate, which is convenient for liquid flow. During detection, the blind plate 101d is replaced with a blind plate without holes for breathing valve detection; the rotating wheel 102a and the handle 102b are an integrated structure; one end of the first rotating shaft 103b passes through the first reversing shell 103a and is connected to the rotating wheel 102a; the first bevel gear 103c and the second bevel gear 103d are arranged inside the first reversing shell 103a, and both ends of the second rotating shaft 103e pass through the first reversing shell 103a; the first coupling 104a can compensate for displacement and buffer transmission to avoid the shaft length being subjected to force and easy deformation due to torque transmission.
