Description

Technical Field

[0001] This utility model relates to a pressure monitoring device for domed oil tanks, belonging to the field of oil storage technology. Background Technology

[0002] As an important oil storage device, dome-shaped oil tanks are widely used due to their advantages such as simple structure, low cost and short construction period. However, high-risk operations such as oil transfer, soaking and flushing, tank cleaning and hot work are frequent. In addition, some oil tanks have been in use for more than 30 years, and the risk of deformation such as tank collapse and local bulging has increased sharply, which has greatly increased the safety pressure of oil depots.

[0003] A domed oil tank consists of three parts: the top, the walls, and the bottom. The pressure inside the tank is regulated by a breather valve. Currently, the main measures to prevent overpressure deformation of oil tanks include regular maintenance of the breather valve, timely checks of the U-shaped pressure gauge by the custodian, and the presence of personnel on duty during operations. However, during oil receiving and dispatching operations, and under conditions of large day-night temperature differences, the pressure difference between the inside and outside of the tank increases. If overpressure is not detected and addressed in time due to breather valve malfunction or negligence on the part of personnel, the tank will inevitably deform once it exceeds its pressure capacity, leading to serious accidents.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a pressure monitoring device for dome-shaped oil tanks. This device can monitor the internal pressure of the dome-shaped oil tank in real time and automatically, enabling early warning and proactive safety protection of the pressure in the dome-shaped oil tank, thereby effectively preventing overpressure deformation of the oil tank.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: The pressure monitoring device for the dome-shaped oil tank includes a first connection port and a second connection port arranged side by side. The second connection port is connected to the bottom port of a tee via a flange. The top port of the tee is connected to a pressure transmitter via a flange. An electric on / off valve and a backup breather valve are connected sequentially to the side port of the tee. The pressure transmitter is connected to the signal input terminal of the oil depot IoT terminal via a first line. The signal output terminal of the oil depot IoT terminal is connected to the electric on / off valve via a second line. The signal output terminal of the oil depot IoT terminal is connected to an alarm via a third line.

[0007] Furthermore, the first connection port and the second connection port are fixed to the dome-shaped oil tank and connected to the top of the inner cavity of the dome-shaped oil tank.

[0008] Furthermore, a main breather valve is connected to the first connection port via a flange.

[0009] Furthermore, the tee valve and the electric on / off valve, as well as the electric on / off valve and the standby breather valve, are all connected via flanges.

[0010] Furthermore, the pressure transmitter includes a transmitter body, which is made of an explosion-proof aluminum alloy housing.

[0011] Furthermore, a measuring end is provided at the bottom of the transmitter body, and the measuring end passes through the inner cavity of the tee.

[0012] Furthermore, a flange is fixed to the outside of the measuring end near the transmitter body.

[0013] Furthermore, the oil depot IoT terminal has a built-in real-time monitoring module, alarm management module, data storage module, and line graph analysis module.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention utilizes a pressure transmitter to monitor the pressure inside the dome-shaped oil tank in real time and automatically, and issues an early warning when the pressure is abnormal. At the same time, it automatically activates the backup safety mechanism and uses the backup breather valve to intervene, thereby effectively preventing the oil tank from overpressure deformation and ensuring the safe operation of the oil tank.
