Floating Ball is a common valve design, mainly used to control the flow of fluid. The following is a detailed introduction to floating ball valve:
1. Structure and working principle
Ball: The core component of the floating ball valve is a hollow sphere, which can float freely in the valve body.
Valve seat: There is a valve seat on each side of the ball, usually made of elastic material (such as PTFE) to ensure sealing.
Valve stem: The valve stem is connected to an external operating mechanism (such as a handle or actuator) to control the rotation of the ball.
Working principle: When the hole of the ball is aligned with the pipeline, the fluid can pass; when the ball is rotated 90 degrees and the hole is perpendicular to the pipeline, the fluid is blocked.
2. Main features
Good sealing: The ball of the floating ball valve is close to the valve seat under the action of fluid pressure to form a good seal.
Easy operation: Only 90 degrees of rotation is required to achieve switching, and the operation is fast and convenient.
Wide range of application: Suitable for a variety of media such as water, oil, and gas.
Compact structure: small size, light weight, easy to install and maintain.
3. Application areas
Oil and gas: used for fluid control in pipelines.
Chemical industry: suitable for the control of various corrosive media.
Water treatment: used for the control of water supply and drainage systems.
Power industry: used for fluid control of boilers and cooling systems.
4. Advantages
High sealing: good sealing performance can be maintained under both low and high pressure conditions.
Low flow resistance: when fully open, the flow channel has the same diameter as the pipeline, and the flow resistance is small.
Long life: the material selection of the valve seat and the ball is reasonable, wear-resistant and corrosion-resistant, and has a long service life.
Easy maintenance: simple structure, easy to disassemble and maintain.
5. Disadvantages
High pressure limit: under high pressure conditions, the ball may generate greater friction, affecting operation.
Temperature limit: the temperature resistance of the valve seat material is limited, and the sealing performance may be affected in high temperature environment.
