Description

Technical Field

[0001] The utility model relates to the technical field of pressure balancing equipment, in particular to a pressure balancing device for explosion-proof storage tanks used in gas stations. Background Art

[0002] The pressure balancing device for explosion-proof tanks used in gas stations is an important safety device designed for skid-mounted gas stations to adjust and stabilize the internal pressure of explosion-proof tanks. The device is mainly composed of a tank device and a balancing device, which is designed to ensure the stability of the internal pressure of the tank during refueling and storage, and to prevent safety risks caused by excessive or low pressure. The device fully considers the explosion-proof requirements and adopts specific materials and structural designs to ensure stability even in extreme cases to prevent explosion accidents. The balancing device includes components such as a device plate, a rotating motor, a balancing machine, a vent pipe, and a threaded pipe. When the internal pressure of the tank increases, the rotating motor drives the balancing machine to work, so that the vent pipe is plugged into the outlet pipe of the tank. The size of the vent pipe opening is adjusted by rotating the threaded pipe, thereby controlling the discharge of gas inside the tank to achieve the purpose of reducing pressure.

[0003] At present, when refueling in an explosion-proof oil tank, it is generally necessary to use a pressure balancing device to exhaust the air in the explosion-proof storage tank, and then refuel so that refueling and exhaust are carried out at the same time to ensure the safety of the oil tank. However, when the air pipe of the balancing device is connected to the explosion-proof oil tank, the gas is generally discharged after the exhaust seat is connected to the connecting seat, and the exhaust seat and the connecting seat are connected by the direction of plugging. Although the connection and disassembly are convenient to a certain extent, the exhaust seat and the connecting seat may be separated due to the influence of the internal air pressure of the explosion-proof oil tank, causing the exhaust pipe to fall off. Therefore, a pressure balancing device for explosion-proof storage tanks for gas stations is proposed. Utility Model Content
