Leakage-proof oil tank

Abstract

The invention relates to the technical field of oil tank truck transportation, and discloses a leakage-proof oil tank which comprises a tank body, a leakage-proof device is mounted at the top of the tank body, a mounting seat is fixedly mounted on the outer side of the leakage-proof device, and a power supply is mounted in the mounting seat. A bag body is arranged in the oil tank body, a liquid inlet frame is arranged outside the bag body, when the tank body inclines, the pressure borne by the inclined face of the tank body exceeds the limited pressure at the moment, conductive liquid in the bag body flows into the liquid inlet frame, and conductive plates which do not make contact with each other circulate through the conductive liquid; as long as the internal oil tank inclines by a certain angle, current between the two current-conducting plates flows and supplies power to a coil, magnetic repulsive force of the coil acts on a movable plate, a channel between the tank body and a breather valve is blocked, therefore the situation that gasoline leaks from the breather valve when the inclination angle is small is avoided, the leakage-proof angle is improved, and leakage waste of gasoline is reduced.

Description

technical field [0001] The invention relates to the technical field of oil tank truck transportation, in particular to an anti-leakage oil tank. Background technique [0002] In the process of oil tank vehicle transportation, gasoline is generally loaded in oil tanks, and in order to balance the internal balance of the oil tank, a breathing valve is installed on the top of the oil tank. The working principle of the breathing valve is mainly that when the internal air pressure increases, the pressure will increase. It acts on the breathing valve, so that the positive pressure breathing valve disc opens, and then the gas is discharged outwards. When the internal air pressure decreases, the negative pressure breathing valve disc opens at this time, and the air is sucked inward to ensure the balance of internal and external gases. [0003] However, due to the bumps, ups and downslopes, and even dumping of the oil tank truck during transportation, when the oil tank tilts, the bre...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing oil tanker breathing valve proposed in the background technology, the present invention provides a leak-proof oil tank, which has the functions of preventing gasoline leakage, expanding the use angle of the blocked breathing valve device, and reducing gasoline waste. Advantages, solve the problems raised in the above-mentioned background technology
