Abstract

The invention discloses a foldable ventilation tube for an oil storage tank of a gas station. The foldable ventilation tube for the oil storage tank of the gas station comprises a fixed ventilation tube body, a rotatable ventilation tube body, a mounting flange and a rotating device, in the use of the novel foldable ventilation tube for the oil storage tank of the gas station, when inspection andmaintaining operation needs to be carried out, a release operating rod is unlocked from a locking pin, the rotatable ventilation tube body is enabled to slowly fall down by holding the release operation rod, then the rotatable ventilation tube body is in a horizontal shape, and therefore inspection and maintenance work can be carried out. The foldable ventilation tube for the oil storage tank of the gas station is simple in structure, convenient to install, capable of being operated by a single person and capable of saving the maintenance time, the safety is improved, all the inspection and maintenance work can be completed by a worker on the ground, and the risk of high-altitude operation is avoided while the inspection and maintenance work is simplified.

Description

technical field [0001] The invention relates to the technical field of breathing tubes for oil storage tanks, in particular to a foldable breathing tube for oil storage tanks in gas stations. Background technique [0002] The oil and gas pressure in the oil storage tank of the gas station will continue to change with the ambient temperature and the amount of oil stored. Therefore, the oil storage tanks in the gas station are equipped with breathing tubes to balance the pressure inside and outside the oil tank to prevent the oil tank from being damaged due to pressure. Too large or too small will cause deformation or damage, while maintaining a certain oil and gas pressure in the tank to reduce oil and gas evaporation. [0003] The oil tank breathing tube is a safety system to ensure the safe operation of the oil tank and reduce the evaporation loss of oil. Regular inspection and maintenance of the breathing tube is an important measure to ensure the normal operation of the o...
