A ball valve is a rotary shut-off valve whose ball rotates around the valve shaft to control the flow of fluid. The main function of a ball valve is to control the flow, direction, pressure and working medium of the fluid. A detailed understanding of what a ball valve is will help you find the right valve manufacturers and select the best ball valve.
Structure of a ball valve
1. Ball: Spherical, with a channel formed in the middle of the ball,
and the on-off of the pipeline is controlled by rotating the ball.
2. Valve seat: A positioning device for the ball, usually made of
metal, plastic or elastic material.
3. Valve stem: An axis that runs through the center of the ball,
connecting the ball and the operating mechanism.
4. Operating mechanism: Includes manual and automatic operating
mechanisms to control the rotation of the ball.
Features of ball valves
1. Simple structure: The ball valve has a simple structural design
and is easy to manufacture and maintain.
2. Good sealing: The sealing ring made of materials such as
polytetrafluoroethylene has good sealing performance.
3. Easy to operate: Just rotate 90 degrees
to switch, easy to operate.
4. Wide range of applications: Suitable for various fluid media,
including corrosive media, mud, oil, etc.
Function of ball valve
1. Shut-off function: The ball valve can
close or open the medium in the pipeline, and play the role of cutting off or
unblocking the pipeline.
2. Adjustment function: The ball valve can
adjust the flow of the medium as needed, control the flow rate and pressure of
the medium.
3. Flow control function: The ball valve
has a simple structure and is easy to operate, and can quickly adjust the flow
of the medium in the pipeline.
4. Direction control function: The ball
valve can change the flow direction of the medium, which is suitable for
occasions where the flow direction of the medium needs to be changed.
Application field
The ball valve has the characteristics of
convenient operation, good sealing, and strong corrosion resistance, so it is
widely used in the following fields:
1. Industry: Ball valves are widely used in
petroleum, chemical, electric power, metallurgy and other industries to control
the flow, pressure and temperature of various liquids, gases, steam and other
media.
2. Construction: Ball valves are used to
control water supply, gas supply, drainage and other aspects in building
pipeline systems. For example, they are used to control the flow and
temperature of cold and hot water media in building air-conditioning systems.
3. Agriculture: Ball valves are widely used
in modern agriculture for agricultural irrigation, fisheries, animal husbandry
and other aspects.
4. Other fields: Ball valves are used in
mining, medicine, food, light industry and other industries to control various
media.
Summary
In short, as a commonly used shut-off
valve, ball valves play an important role in pipeline systems and are widely
used in different fields, with broad market prospects and development space.
