Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breathing pipes, and more specifically, to a foldable oil tank breathing ventilator. Background Art
[0002] The oil tank breathing vent pipe is used to stabilize the air pressure in the oil tank by connecting the air inside and outside the oil tank. When the oil in the oil tank decreases, air flows into the oil tank through the breathing vent pipe to ensure the stability of the air pressure in the oil tank; when the oil in the oil tank increases, air flows out of the oil tank through the breathing vent pipe to ensure the stability of the air pressure in the oil tank. It can maintain the balance of air pressure inside and outside the oil tank, avoid the occurrence of these safety problems, and prevent abnormal oil tank pressure and oil inlet and outlet failures.
[0003] However, according to the requirements of the oil tank breathing ventilation pipe, the breathing valve should be 4.2m or more above the ground. This means that during daily maintenance and inspection, maintenance personnel must perform high-altitude operations, which is not only inconvenient but also easily leads to high-altitude fall accidents.

The folding device is a bowl-shaped interface member which is symmetrical up and down and can be sealed to each other. An upper bowl-shaped interface member 4 is fixedly provided with an upper rotating hinge 401 on the outer edge, and a lower bowl-shaped interface member 5 is provided with a lower rotating hinge 501 on the outer edge. Both the upper rotating hinge 401 and the lower rotating hinge 501 are provided with a through hole 6 for inserting a rotating shaft 7. The upper bowl-shaped interface member 4 and the lower bowl-shaped interface member 5 can rotate with the rotating shaft 7 as the axis.
[0038] Through the above technical solution, when the upper ventilation duct 2 needs to be maintained and repaired, the upper rotating hinge 401 is rotated with the rotating shaft 7 as the axis, so that the upper ventilation duct 2 is rotated downward until it reaches a suitable maintenance and repair position. At this time, due to the telescopic performance of the bellows 8, the upper ventilation duct 2 and the lower ventilation duct can still perform normal breathing functions;
[0039] Specifically, the bowl-shaped interior of the upper and lower bowl-shaped interface parts is provided with a pagoda joint 9 for connecting the bellows 8, and the bellows 8 and the pagoda joint 9 are fixed with the aid of a clamp. The bellows 8 is used for air circulation through the upper ventilation pipe 2 and the lower ventilation pipe 3, and the bowl-shaped exterior of the upper and lower bowl-shaped interface parts is provided with a pipe with an internal thread 10, which is fixed to the ends of the upper and lower ventilation pipes through the internal thread 10. The connection of the pagoda joint 9 with the bellows 8 is easy to install and has good sealing performance. And the bellows 8 in this embodiment is an oil-resistant and acid-resistant bellows 8.
[0040] Specifically, a sealing ring is provided between the bowl openings of the upper and lower bowl-shaped interface members, and a clamping ring 11 is provided on the outer edge of the bowl openings of the upper and lower bowl-shaped interface members, and the clamping ring 11 is used to fix the clamping hoop 12.
[0041] Through the above technical solution, the purpose of the sealing ring is to ensure the sealing of the interface between the upper and lower bowl-shaped interface parts. The clamp 12 is used to fix the upper and lower bowl-shaped interface parts, and the clamp 12 has the advantage of being easy to disassemble.
[0042] Specifically, a reinforcing cover is arranged in the cavity of the bowl-shaped interface member, one end of which is fixed to the pipe in the cavity of the bowl-shaped interface member, and the other end is fixed to the convex surface of the bowl-shaped interface member, playing a role similar to a reinforcing rib, thereby enhancing the service life of this embodiment.
[0043] Specifically, the lower bowl-shaped interface member is provided with a vent hole 17, which is used to connect the air in the cavity of the bowl-shaped interface member 5 with the outside air, effectively preventing the internal air pressure of the bowl-shaped interface member 5 from damaging this embodiment due to weather changes.
