Product introduction
The three-piece ball valve is a prevalent type of valve utilized across various sectors, including oil, chemical, and metallurgical industries. Its intricate internal design necessitates a detailed examination. This discussion will dissect the three-piece ball valve's anatomy, focusing on its exterior, construction, and operational mechanism.
**Exterior and Material Overview**
The three-piece ball valve is composed of a pair of flanges sandwiching a spherical element. This design ensures simplicity, robust sealing properties, and an extended operational lifespan. The primary construction materials include carbon steel and stainless steel, with the option to opt for alternative materials based on specific environmental demands.
**Detailed Internal Components**
1. **Flange Assembly**: The flanges, both upper and lower, serve as the structural backbone of the valve. They house essential components such as spring washers and sealing rings.
2. **Central Sphere**: The sphere, the valve's pivotal element, is made up of two semicircular sections joined by bearings. A sealing ring is strategically placed between these sections to ensure a tight seal.
3. **Valve Stem**: This component links the operating handle to the central sphere, facilitating the transfer of force. It also incorporates a sealing ring to prevent any leakage of the contained medium.
4. **Sealing Mechanism**: The valve's sealing mechanism relies on spring washers and sealing rings. The spring washers provide support to the central sphere, while the sealing rings are crucial for preventing any medium leakage.
**Operational Dynamics**
The valve operates through the rotation of the handle, which in turn rotates the stem and the central sphere. When the sphere aligns with the flange's opening, it allows the medium to pass through the valve. Further rotation of the handle adjusts the flow direction. In the closed position, the sphere forms a tight seal with the flange, preventing any leakage.
