Electric flange butterfly valve is a device used for medium flow control and pipeline displacement compensation in industrial pipeline systems. It mainly achieves sealing and regulating functions of pipeline systems through flange connections. It is an automated control device that combines electric actuators and flange butterfly valves. It uses electric energy to drive the butterfly plate to rotate (0 ° -90 °) to achieve the opening and closing of pipeline media and flow regulation. It is widely used in fields such as petroleum, chemical, water treatment, and power.
Advantages:
Compact structure, flexible installation, flange connection for easy installation and disassembly, suitable for high-pressure large-diameter pipelines. Simple structure, small size, light weight, and saves installation space. Quick opening and closing, simple operation, the butterfly plate can be rotated 90 ° to complete opening and closing, with small operating torque and fast opening and closing speed.
The soft seal valve adopts elastic materials to achieve good sealing under low pressure; Hard sealed valves are designed with both metal hard seals and elastic seals to adapt to high temperature and high pressure conditions.
working principle
Electric actuator drive: After receiving the control signal, the motor starts and transmits the rotational motion to the valve stem through the transmission device. The valve stem drives the butterfly plate to rotate around the axis, with a rotation angle range of 0 °~90 °.
Butterfly board opening and closing control
Closed state: The butterfly plate rotates to 0 ° and tightly adheres to the valve seat, blocking the flow of the medium.
Open state: The butterfly plate rotates to 90 °, parallel to the fluid flow direction, forming a large circulation channel.
Adjustment status: Rotate the butterfly plate to between 0 ° and 90 °, and adjust the medium flow rate by controlling the opening.
Main functions
Flow regulation: By rotating the butterfly plate to control the medium flow, it is suitable for scenarios such as water supply and drainage, energy systems, etc. that require accurate flow control.
Displacement compensation: Adopting a flange connection structure, it can adapt to the displacement changes caused by thermal expansion and contraction of pipelines, reducing the risk of leakage.
Media interception: It plays a role in blocking the flow of media when necessary, such as in the safety cutoff requirements of industries such as chemical and pharmaceutical.
