I.Basic Structure

The structure of butterfly valve is mainly composed of several core parts. The valve body as the infrastructure of the butterfly valve, its shape is mostly round or oval, and the material selection is extremely sophisticated, such as corrosion-resistant cast iron,

high-strength cast steel and stainless steel resistant to special media. The valve body not only provides stable support for the butterfly valve, but also builds a fluid flow channel, the selection of different materials is designed to fit the complex and diverse industrial production environment, whether it is conventional water, gas transmission, or corrosive chemical fluid transmission, can cope with freely. The butterfly plate is the core component of the butterfly valve, which is like a rotating disk placed inside the valve body, and the size is precisely adapted to the valve diameter. During operation, the disc rotates flexibly around a specific fixed shaft, and the fine gap between the edge and the inner wall of the valve body not only ensures the smooth rotation of the disc, but also maintains the compactness of the overall structure of the valve.

II.Working Principle

The working principle of the butterfly valve is based on the rotating motion of the butterfly plate around the axis of the valve stem. When the butterfly valve needs to be opened, the drive device receives the opening instruction, generates the corresponding torque and transmits it to the butterfly plate through the valve stem, and the butterfly plate begins to rotate counterclockwise around the axis. As the disc rotates, the seal between it and the seat is gradually separated, and the fluid channel is gradually opened to allow fluid to pass through the valve. When the disc is rotated to the 90° position, the valve is fully open, and the fluid flows almost unhindered in the pipe, and the flow rate is maximum. When the butterfly valve is closed, the driving device outputs torque in reverse according to the closing instruction, and the valve stem drives the butterfly plate to rotate clockwise. As the plate moves closer to the seat, the fluid passage Narrows. When the disc is turned back to the initial 0° position, the disc is tightly fitted with the sealing surface of the valve seat, completely blocking the fluid flow and closing the valve. During the whole opening and closing process, the precise adjustment of the fluid flow can be achieved by precisely controlling the rotation Angle of the butterfly plate.

Sealing Property

The sealing design of the butterfly valve is unique, and the valve seat is closely fitted with the butterfly plate to form a tight sealing structure. When the valve is closed, it can effectively resist the impact of high pressure fluid and prevent medium leakage. Even in the face of corrosive media, special sealing materials can ensure long-term stable sealing effect, provide a safe and reliable guarantee for industrial production, and avoid production accidents and environmental pollution caused by leakage.

Compact Structure

The butterfly valve uses a compact structure design, compared with other types of valves, small size, light weight. This feature makes it unnecessary to use large lifting equipment during the installation process, saving labor and time costs. At the same time, in the pipeline system with limited space, the butterfly valve can be flexibly installed and will not occupy too much space, which provides convenience for pipeline layout optimization.

Low Operating Torque

The butterfly valve is designed so that the disc rotates with minimal operating torque during opening and closing. When manually operated, the operator only needs to easily turn the handle to realize the opening and closing action of the valve, which greatly reduces the labor intensity. If electric, pneumatic or hydraulic drive is used, the power required for the drive device is also reduced, which improves the ease of operation and reduces energy consumption.

Three-eccentric Center

Butterfly Valve

The core advantage of the three-eccentric center butterfly valve is its excellent sealing performance. The unique three-eccentric structure is the key. The first eccentric makes the sealing surface of the butterfly plate in linear contact with the seat during initial contact, greatly increasing the specific sealing pressure. The second eccentric optimization of the opening and closing trajectory of the disc reduces the friction and wear of the sealing surface to ensure long-term stable sealing. The third eccentricity ensures that the sealing surface is detached when the butterfly plate is fully opened to prevent media erosion damage. With enhanced polytetrafluoroethylene, rubber and other high-performance sealing materials, in high pressure, high vacuum and strong corrosion and other harsh conditions, can also achieve zero leakage, providing reliable fluid seal protection for industrial production.

We have an excellent technical team

J-VALVES Company Specializes In The Production of High-quality Butterfly Valve Products

The working principle of the butterfly valve is based on rotational motion. The driving device causes the valve stem to drive the butterfly plate to rotate. When the butterfly plate is parallel to the axis of the pipeline, the valve is fully open and the fluid flows smoothly; when it is vertical, the valve is fully closed to cut off the fluid. During the rotation of the butterfly plate, changing the angle with the flow direction of the fluid can adjust the

cross-sectional area of the flow. The smaller the angle, the greater the flow, and vice versa.
