[0023] Please refer to Figures 1-2In this embodiment, the flange seat 101 has a groove 301 on its surface, and a sealing ring 302 is disposed inside the groove 301, and the sealing ring 302 is fixedly connected to the flange seat 101. The sealing ring 302 is positioned and installed by setting the groove 301, and the sealing ring 302 can improve the sealing performance at the connection when the flange seat 101 is connected to the flange ring 201. A flat washer 402 is provided around the hexagon socket head cap screw 3, and the flat washer 402 is located on one side of the flange ring 201. A spring washer 401 is provided around the hexagon socket head cap screw 3, and the spring washer 401 is located on one side of the flat washer 402. The spring washer 401 provides additional tightening force and improves the tightness of the connection, and the flat washer 402 can increase the friction and prevent the hexagon socket head cap screw 3 from loosening.

[0024] Please see Figures 3-4 In this embodiment, the protective assembly includes a protective cover 501 and a water immersion sensor 502. The protective cover 501 is fixedly installed on one side of the oil tank 1, located around the flange seat 101. The water immersion sensor 502 is fixedly installed inside the protective cover 501, located directly below the connection between the flange ring 201 and the flange seat 101. The protective cover 501 protects the connection between the flange ring 201 and the flange seat 101, preventing external forces from affecting the connection. The water immersion sensor 502 alerts relevant personnel in the event of oil leakage. The model of the water immersion sensor 502 is BLM2-SJ516C. The protective assembly also includes a rotating door 503 and a hinge 504. The rotating door 503 is located on one side of the protective cover 501, and two sets of rotating doors 503 are provided. The rotating door and the protective cover 501 are rotatably connected via the hinge 504. The rotating door 503 can shield and protect the interior of the protective cover 501. A hinge 504 allows the rotating door 503 to rotate, facilitating the disassembly and maintenance of the flange seat 101 and flange ring 201 inside the protective cover 501. The protective assembly includes an oil drain port 505 and a cover 506. The oil drain port 505 is located at the bottom of the protective cover 501, and the cover 506 is located below it.

[0025] During operation, the flange ring 201 and the flange seat 101 can be fixedly connected by the internal hexagonal head screw 3, thereby fixing the oil drain valve body 2 to one side of the oil tank 1. This installation method is easy to install, has fewer welding surfaces, and is not prone to rust.

[0026] The spring washer 401 provides additional tightening force to improve the tightness of the connection. The flat washer 402 increases the friction to prevent the internal hexagonal head screw 3 from loosening, making the connection more stable.

[0027] The protective cover 501 can protect the connection and prevent external forces from affecting the connection. If oil leakage occurs at the connection, the water immersion sensor 502 can quickly alert relevant personnel. The protective cover 501 can also limit the leakage of oil and prevent it from polluting the environment.

[0028] By removing the cover 506, the oil inside the protective cover 501 can be drained through the drain port 505. The two sets of rotating doors 503 can be fixed by using the pin 602 and the connecting plate 601. When it is necessary to disassemble and maintain the interior, it is also convenient to open the rotating door 503 using the hinge 504.

The connection between the flange ring 201 and flange seat 101 is fixed by setting the internal hexagonal head screws 3. This installation method has fewer parts, is easier to install, has fewer welding surfaces, is less prone to rust, and is less likely to cause paint film peeling. It has better sealing performance and reduces oil leakage at the connection. This solves the problems of traditional drain valve installation structure, which is usually a pipe joint installation structure. It has many welding surfaces, complex structure, easy local paint film peeling, rusting of pipe joints, affecting appearance, and even causing oil leakage in severe cases. In addition, the operation of installing drain valve is cumbersome, time-consuming, and requires many parts.
