Below I will analyze in detail all aspects of Velan high temperature ball valve, including its definition, structural characteristics, working principle, technical advantages and application fields.

2. Structural features of Velan high temperature ball valve

Overall structure: Velan high temperature ball valve is composed of valve body, ball, valve stem, sealing ring and other components. Among them, the valve body is made of special materials and can withstand thermal stress and mechanical stress in high temperature environments. The ball is located in the center of the valve body and rotates to cut off or regulate the fluid. In order to ensure reliable sealing in high temperature environments, sealing rings are usually made of materials with strong high temperature resistance, ball valve supplier.

Sphere design: The ball of Velan high temperature ball valve usually adopts spherical design with streamlined channel, which can reduce fluid resistance and improve flow coefficient. In order to ensure mechanical strength and corrosion resistance in high-temperature environments, the ball material is usually stainless steel or high-temperature alloy.

Sealing structure: In order to ensure reliable sealing in high temperature environments, Velan high temperature ball valves adopt metal-to-metal sealing structures or metal-to-non-metal sealing structures. Among them, the metal-to-metal sealing structure can withstand thermal stress and mechanical stress in high-temperature environments, ensuring reliable sealing under high pressure differences; while the metal-to-non-metal sealing structure can utilize the elastic properties of non-metal materials to achieve a tighter seal. Effect.

3. Working principle and technical advantages of Velan high temperature ball valve

Working principle: The working principle of Velan high temperature ball valve is to open, close and adjust the fluid channel by rotating the ball. When the ball rotates 90 degrees, the fluid channel is fully opened or closed; when the ball rotates to a certain angle, the fluid flow can be adjusted. By controlling the rotation angle of the sphere, precise control of fluid flow can be achieved. At the same time, in order to ensure reliable operation in high temperature environments, Valen high temperature ball valves are usually equipped with special actuators or driving devices, gate valve factory.
