Product Description

Working Principle of Electric Regulating Butterfly Valve

The electric regulating butterfly valve is composed of an electric actuator and a butterfly valve, so it has the advantages of easy operation and simple structure of the butterfly valve, and is also widely used in industries such as chemical and pharmaceutical industries. With the assistance of electric actuators, the development of butterfly valves has taken it to a new level. The principle of electric regulating butterfly valve is to drive the valve stem through an electric device, causing the butterfly plate to rotate 90 ° to achieve the opening and closing of the valve.

The principle of the electric actuator is actually very simple, just like the Razor in daily use, the energy source is electricity, which drives the operation of the valve plate, so as to open and close the valve and flow or stop the fluid. The electric actuator of electric regulating butterfly valves can be divided into switch type and regulating type, and the switch type electric regulating butterfly valve serves as a switch; The adjustable electric regulating butterfly valve plays a role in regulating flow, accurately adjusting the flow to micrometers, and is also a relatively expensive valve. As a device installed in pipelines, it may not seem very practical to inspect the on-off status of valves on site, resulting in the presence of feedback signals. The regulating type itself comes with feedback signals, while the switching type can choose whether to install feedback signals according to the specific needs of the customer. Here, I would like to introduce the storage method of electric regulating butterfly valves.

1. The product should be stored in a dry and ventilated room, and should not be stored outdoors; The sealing ring should not come into contact with oily substances to avoid aging.

2. Storage and Transportation:

A. Use blind covers at both ends of the diameter to prevent dust and rust, and keep the channel clean.

B. The machined surfaces of both ends of the electric regulating butterfly valve should be cleaned of dirt and coated with rust inhibitor.

Electric regulating butterfly valves with a storage period exceeding 18 months should be retested before installation and use to ensure the integrity of their structure and function.

When placing the electric regulating butterfly valve, it should be ensured that the electric device is not squeezed or the wiring terminals are damaged, and to prevent contact with corrosive substances. Handle with care to avoid damage to electrical components and Machine element.
