Technical experts detail the principle and use of electric butterfly valve

The electric butterfly valve is composed of a high-precision electric actuator and a high-quality butterfly valve. It has the high-precision actuator and the butterfly valve is easy to operate and simple in structure. The electric butterfly valve is widely used in chemical, pharmaceutical and other industries. And because of the assistance of electric actuators, the development of butterfly valves has taken a new step. The working principle of the electric butterfly valve: the valve stem is driven by the electric device, so that the butterfly plate produces a 90° rotary motion to achieve the opening and closing of the valve.
The principle of electric actuator: through the connection of 220V or 380V power supply, the output shaft of the actuator is driven by the power supply, and the output shaft drives the operation of the valve plate, thereby achieving the function of opening and closing the valve and circulating or shutting off the fluid. The electric actuator of the electric butterfly valve can be divided into a switch type and an adjustment type, and the switch type electric butterfly valve functions as a switch; and the regulating type electric butterfly valve functions to adjust the flow rate, and can accurately adjust the flow rate to a thousand degrees. It is also a valve with a relatively high price. The valve, as a device installed in the pipeline, does not seem to be very realistic if it is checked in the field, so there is a feedback signal. The adjustment type itself has a feedback signal, and the switch type can choose whether to install the feedback signal according to the specific needs of the customer.
Here, I will introduce you to the storage method of the electric butterfly valve.
1. The product should be stored in a dry and ventilated room and should not be stored in the open air; the sealing ring should not be in contact with oily substances to avoid aging.
2, Storage: A, both ends of the path with a cover, dust, rust, keep the channel clean. B. The processing surfaces on both ends of the electric butterfly valve should be cleaned of dirt and coated with anti-rust product.
3. Electric butterfly valves with a storage period of more than 18 months should be re-tested before installation to ensure structural and functional integrity.
4. When the electric butterfly valve is placed, it should be ensured that the electric device is not damaged by the extrusion and the terminal, and the contact with corrosive substances is prevented. Handle with care to avoid damage to electrical components and mechanical parts.
