Background Technology

[0002] High-temperature and high-pressure anti-sulfur throttling valve is a type of throttling valve that can operate in high-temperature and high-pressure environments, and is particularly suitable for working conditions containing corrosive media such as hydrogen sulfide; this type of valve is usually made of special materials and undergoes special treatment to enhance its resistance to sulfide corrosion. The high-temperature, high-pressure, sulfur-resistant throttling valve's outer shell is manufactured through casting. After processing, it requires grinding and polishing. Not all areas need grinding; the areas requiring grinding are the pipe connections, specifically the outer surface of the flange connection of the throttling valve's outer shell. In existing technology, grinding is performed using a device, as disclosed in the patent announcement CN218518337U, which is a grinding device for the outer shell of a sulfur-resistant throttling valve. This device includes a support, a grinding table rotatably connected to the top surface of the support, and a first drive motor fixedly connected to the bottom surface of the support. One end of the output shaft of the first drive motor is fixedly connected to the grinding table. Next, a drive bevel gear is rotatably connected to the bottom surface of the grinding table, and a second drive motor is fixedly connected inside the grinding table. One end of the output shaft of the second drive motor is fixedly connected to the drive bevel gear. A set of first threaded screws is rotatably connected to the inner wall of the grinding table. One end of each set of first threaded screws is fixedly connected to a driven bevel gear. The peripheral surfaces of each set of driven bevel gears mesh with the drive bevel gear. The peripheral surfaces of each set of first threaded screws are threadedly connected to a moving block. The top surface of each set of moving blocks is fixedly connected to a clamping rod.

In the aforementioned prior art, the main body of the antisulfur throttling valve is fixed from the bottom during grinding. Its positioning mechanism is complex and unstable, and it cannot be rotated during grinding. The grinding and positioning mechanisms are adjusted by screw drive, which is complex and costly.

The second angle grinding and polishing block 8 is fixedly connected to the inner surface of the first angle grinding and polishing block 7 by bolts 9; this facilitates the fixing of the second angle grinding and polishing block 8 to the first angle grinding and polishing block 7. The fixing is convenient and firm, and the grinding clamping distance can be adjusted. The flange of the anti-sulfur throttling valve housing body 4, which is not easy to thicken, can be adjusted to fit and grind, making grinding convenient. The outer end of the second angle grinding and polishing block 8 is provided with a positioning protrusion, which is attached to the inner surface of the first angle grinding and polishing block 7.
