Description

Technical Field

[0001] This utility model relates to the technical field of rotatable oil tank metering orifices, and particularly to rotatable oil tank metering orifices. Background Technology

[0002] Currently, all oil gauging ports are fixed connections. During daily operations, when opening the measuring port to measure oil and take samples, the dipstick must always remain in contact with the soft metal of the gauging port, making it impossible to effectively prevent the inhalation of oil vapor. According to on-site operational requirements, oil tanks used for trade transactions must be manually measured daily, resulting in a heavy workload. Over time, this will inevitably impact human health. Furthermore, the existing fixed metering ports on oil tanks prevent adjustments to the operator's position based on wind direction, ensuring the operator remains upwind. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a rotatable oil tank metering orifice, ensuring that the operator is always positioned upwind.

[0004] This utility model provides a rotatable oil tank metering orifice, including a metering orifice disposed on an oil tank, a fixed part connected to the metering orifice via a flange, a connecting part connected to the fixed part, and a rotating part rotatably connected to the connecting part. An oil hole cover is disposed on the top of the rotating part, and the oil hole cover is hinged to the metering orifice. The fixed part and the rotating part are internally vacuumed, and the connecting part, the rotating part, and the connecting part are coaxially arranged.

[0005] Preferably, the outer wall of the rotating part is provided with a roller, the inner wall of the connecting part is provided with a limiting groove adapted to the roller, and a sealing ring is provided between the rotating part and the connecting part.

[0006] Preferably, the fixing part is provided with a first flange, and the oil tank is provided with a second flange. The first flange and the second flange are connected by a first bolt and an electrostatic bridging copper strip of the first flange.

[0007] Preferably, the first flange electrostatic bridging copper sheet includes a [type gasket] that is connected to the upper surface of the first flange and the lower surface of the second flange, respectively.

[0008] Preferably, the upper part of the rotating part is provided with a third flange, and the lower part of the oil hole cover is provided with a fourth flange. The third flange and the fourth flange are connected by a second bolt and a second flange electrostatic bridging copper sheet.

[0009] Preferably, a pressure rod is provided on the top of the oil hole cover;

[0010] One end of the pressure rod is hinged to the fourth flange, and an opening pedal is provided at the end near the hinge. The other end of the pressure rod is provided with a limit groove, and a fastening screw adapted to the limit groove is hinged to the fourth flange.

[0011] Preferably, the pressure surface of the opening pedal is provided with a corrugated groove.

[0012] Beneficial effects of this utility model

[0013] This invention provides a rotatable oil tank metering orifice that follows wind direction changes, ensuring the operator remains upwind during operation. This reduces fatigue and operational errors caused by poor positioning, thus minimizing metering errors and static electricity generation. It calculates accurate oil data while meeting standard operating procedures, minimizing the risk of occupational diseases from leaking oil vapors during tank top measurements and sampling. The invention features a simple structure and flange connection, allowing for repeated disassembly and maintenance. It is suitable for metering orifices on various oil tanks.
