The three-piece ball valve is a valve widely used in fluid control systems. Its main uses include cutting off, distributing and changing the flow direction of the medium. Due to its structural characteristics and superior performance, it plays a key role in a variety of industrial and daily scenarios. The specific applications are as follows:
1. Applicable media
The three-piece ball valve is suitable for a variety of working media, including:
General fluid: such as common media such as water, solvents, acids, natural gas, etc.
Harsh conditions medium: such as corrosive or high-pressure fluids such as oxygen, hydrogen peroxide, methane, ethylene, etc.
2. Core functions
Cut-off function: Quickly cut off the flow of the medium in the pipeline to achieve efficient opening and closing (only need to rotate 90°).
Distribution function: By changing the flow direction (such as straight-through, three-way or right-angle design), the medium can be diverted or merged.
Control function: In the automation system, it is matched with pneumatic or electric actuators (with platform design) to achieve remote or automatic control.
3. Main application industries
Three-piece ball valves are widely used in the following fields due to their good sealing, strong pressure resistance (suitable for high-pressure environments), and convenient maintenance:
Chemical and petroleum: used to handle media such as acids, solvents, and oil products, and support system control and distribution.
Energy and electricity: plays the role of cutting off and flow regulation in power generation and natural gas transmission.
Light industry and food and pharmaceuticals: suitable for sanitary fluid management in food, pharmaceuticals, refrigeration and other industries (such as internal thread connection design).
Special industries: including papermaking, atomic energy, aviation, rockets and other fields, especially in vacuum or high-pressure systems.
4. Outstanding advantages
Convenient maintenance: The three-piece structure (the left and right valve bodies and the middle valve body are connected by bolts) is convenient for disassembly and replacement of sealing rings, reducing downtime.
High-pressure adaptability: Compared with one-piece or two-piece ball valves, it has higher pressure resistance, which can reach more than 6.9 MPa.
Full-bore design: small fluid resistance, strong flow capacity, suitable for high flow demand scenarios.
