Description

Technical Field

[0001] The utility model relates to a special valve, in particular to a valve body structure of a special valve, belonging to the technical field of valves. Background Art

[0002] Special valves refer to valves that, compared with ordinary industrial valves, have special structures, special materials, special processes, special functions, or are suitable for special working conditions (media, temperature, pressure, media properties, etc.). Special valves play an important role in industrial production and are widely used in chemical, petroleum, metallurgy, electric power, military and other fields. For example, high-temperature valves can be used in heating of thermal power station boilers, high-temperature treatment of oil refining processes, and other occasions.

[0003] After searching, a Chinese patent application with publication number CN215673819U discloses a valve comprising a pipeline, with connecting flanges provided at both ends of the pipeline, a valve body provided on the pipeline, and the valve body being a rectangular box-shaped body, with both ends of the valve body being connected to the pipeline. A hydraulic rod is provided at the upper end of the valve body, which extends out of the valve body and connects to an external hydraulic device. A valve is provided at the lower end of the hydraulic rod. The downward extension of the hydraulic rod can drive the valve downward, thereby sealing the pipeline. To solve the above technical problems, the present utility model provides a valve that can prevent or reduce wear of the valve assembly.

[0004] Although the above patent can avoid or slow down the wear of the valve assembly, it is difficult to perform gas detection on the special valve before use. When the valve is installed, it is easy to collide, causing gas leakage and prone to safety accidents. To this end, we provide a special valve body structure to solve the above problems.
