Internal thread ball valve: structure and application

Internal thread ball valve, also known as internal thread ball valve or internal thread ball type globe valve, is a common type of valve. Its main feature is to open or close fluid channels by rotating 90 degrees. Its working principle is to control the flow of fluid through a sphere. When the sphere rotates parallel to the pipeline axis, the fluid can pass through; When the sphere rotates 90 degrees perpendicular to the pipeline axis, the fluid flow is completely cut off.

Structural characteristics

Internal thread ball valve mainly consists of the following parts:

1. Valve body: It is the main body of the valve, used to connect pipelines.

2. Sphere: located inside the valve body, it can rotate freely and control the flow of fluid.

3. Valve stem: used to operate the switch of the ball.

4. Handwheel: usually located at one end of the valve stem, used to manually rotate the valve stem.

5. Seals: Ensure that the fluid does not leak when in the closed state.

The internal thread design allows this ball valve to be directly screwed into the pipeline, making installation simple and fast. In addition, due to its simple structure, small size, light weight, and good sealing performance, internal thread ball valves are widely used in pipeline systems in industries such as petroleum, chemical, metallurgy, and power.

Whether in the home or industrial field, internal thread ball valves are indispensable and important equipment. Its emergence greatly facilitated people's production and life, providing strong support for the development of modern industry.
