Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a two-piece threaded ball valve with a direct-mounted high platform. Background Art

[0002] A two-piece threaded ball valve is a commonly used type of ball valve. The spherical design of the valve core inside this type of valve structure can conveniently and flexibly control the flow of fluid. However, there are still some problems in the specific use of this type of two-piece threaded ball valve.

[0003] Two-piece threaded ball valves are often threaded at both ends to the corresponding pipeline structure, which leads to installation restrictions between the device and the pipeline, and is not easy to be flexibly disassembled and replaced independently during use. In addition, the operating handle used to control the on-off state is easily loosened due to the impact of the liquid medium during use, which will affect the stability of the opening and closing state of the device. Based on this, we propose a new two-piece threaded ball valve with a direct-mounted high platform. Utility Model Content
