The manual oil pouring port is sequentially provided with a sealing cover mounting flange 20, an oil pouring port filter screen 21 and a grating 22 from top to bottom, and the sealing cover mounting flange 20 is connected with the sealing cover 5. And sealing structures are arranged between the sealing cover 5 and the sealing cover mounting flange 20 and between the sealing cover 5 and the top of the tank body 1. The lower end of the manual oil pouring port is connected to an oil isolation area 6, and the oil isolation area 6 is a columnar separation area arranged in the tank body 1. The oil liquid isolation area 6 passes through the nitrogen seal layer and leads to the bottom of the tank body 1, the side wall of the bottom of the oil liquid isolation area 6 is provided with a liquid pressure release valve 18, and the upper part of the oil liquid isolation area 6 is provided with a one-way air valve 19 communicated with the nitrogen seal layer.
When manually pouring liquid into, open sealed lid 5, the air can get into fluid isolation region 6, and the liquid level of fluid isolation region 6 generally can the parallel and level or be higher than jar internal liquid level of body 1 because liquid relief valve 18 only can let wherein fluid flow out jar body 1 after 6 fluid in fluid isolation region reach certain pressure, and this can prevent that liquid relief valve 18 from exposing and leading to the air admission. After the oil liquid is poured, the oil liquid enters the tank body 1 through the liquid pressure release valve 18, and the sealing cover 5 is covered and tightly sealed after the oil liquid is supplemented. In this case, the oil isolation area 6 has air therein, which must be exhausted. And (3) filling nitrogen, wherein the nitrogen sealing layer is filled into the oil isolation area 6 through the one-way air valve 19, and the filled nitrogen can discharge air from the one-way air valve 19 on the sealing cover 5 to ensure that the oil is sealed by the nitrogen to form the nitrogen sealing layer. Therefore, the storage tank which needs to be manually poured with liquid under certain conditions can also ensure that the liquid is isolated from air, so as to prevent spontaneous combustion.
The tank body 1 is characterized in that a liquid level meter is arranged at the top of the tank body 1, and a measuring rod of the liquid level meter extends into the tank body 1.

Therefore, the flammable liquid is isolated from the air to prevent spontaneous combustion by filling the nitrogen gas at the upper part to form the nitrogen sealing layer, and the liquid is ensured not to be easily leaked even if the liquid volatilizes. The nitrogen sealing valve 11 ensures that the air pressure in the tank body 1 is maintained at a safe level, the pressure of the discharged liquid is reduced, the nitrogen is automatically supplemented, after the liquid is added, the redundant nitrogen can enter the nitrogen temporary storage tank 12 through the breather valve 14, and the normal pressure difference between the tank body 1 and the outside is ensured. Since the expiratory pressure of the breather valve 14 is greater than that of the one-way expiratory valve 13, there is no need to worry about the external gas entering the tank 1. When the temperature rises or liquid is added, the pressure of the nitrogen in the tank body 1 rises, and the pressure in the nitrogen temporary storage tank 12 is equivalent to the expiratory pressure of the one-way expiratory valve 13, so that the nitrogen in the tank body 1 can be discharged into the nitrogen temporary storage tank 12 and then discharged through the one-way expiratory valve 13. When the air temperature drops or liquid is discharged, the air pressure in the tank 1 is reduced, and the tank 1 firstly obtains nitrogen from the nitrogen sealing valve 11. If the nitrogen pipeline 2 cannot supplement nitrogen in time due to faults or insufficient nitrogen, the air pressure in the tank body 1 is reduced to a certain level, the nitrogen in the nitrogen can be supplemented to a nitrogen sealing layer through the breather valve 14 by the nitrogen temporary storage tank 12, the use of the storage tank is not influenced in a short time, and the time is reserved for maintenance and ventilation.
