As a common type of valve, ball valves play an important role in industrial and civil fields. Its main functions can be summarized as follows:
First, cut off and distribute the medium
Cut off the flow: The ball valve controls the flow path of the medium by rotating the ball, and when the ball is rotated to the vertical position of the pipeline, the flow of the medium can be cut off to achieve the closure of the pipeline.
Distribution media: In complex pipeline systems, ball valves can be used to distribute media flow to different branches or equipment to ensure reasonable distribution and utilization of media.
Second, adjust and control the flow
Flow regulation: Although the ball valve is mainly used for switch control, some specially designed ball valves (such as V-shaped ball valves) also have the function of regulating flow. By rotating the sphere to different angles, the channel can be partially opened or closed, thus achieving precise regulation of the flow rate.
Control pressure: In the need to control the pressure of the medium, the ball valve can be used with the pressure control system to control the pressure in the pipeline by adjusting the flow of the medium.
Third, change the flow direction of the medium
Multi-pass ball valve: Multi-pass ball valve (such as T-type and L-type) can not only cut off and distribute the medium, but also change the flow direction of the medium. By rotating the sphere to different positions, the confluence, diversion and flow direction of the medium can be realized.
Fourth, other roles
Good sealing performance: The ball valve uses a metal ball to form a seal between the seat, sealing performance is reliable, can withstand high pressure and temperature.
Easy operation: The opening and closing of the ball valve only need to rotate 90 degrees, easy and fast operation, and the required operating torque is small.
Wide range of application: Ball valve is suitable for a variety of media and working conditions, including water, solvents, acids, natural gas and other general working media, as well as oxygen, hydrogen peroxide, methane and ethylene and other harsh working conditions of the media.
Easy maintenance and repair: The structure of the ball valve is relatively simple, and the maintenance and repair are more convenient. When a seal or sphere needs to be replaced, it can be replaced simply by removing the corresponding component.
In summary, the ball valve has many functions in the pipeline system, such as cutting off and distributing media, regulating and controlling flow, changing the direction of media flow, etc. At the same time, its good sealing performance, simple operation mode and wide range of application make the ball valve widely used in various fields.
