The electric butterfly valve is composed of a valve composed of an electric actuator and a butterfly valve, so it has the advantages of simple operation and simple structure of the butterfly valve. It is also widely used in chemical, pharmaceutical and other industries. And because of the assistance of the electric actuator, the development of the butterfly valve has reached a new level. The principle of the effect of the electric butterfly valve: the valve stem is driven by an electric device to make the butterfly plate produce a 90° rotation movement to reach the opening and closing of the valve.
The electric actuator of the electric butterfly valve can be divided into on-off type and adjusting type. The on-off type electric butterfly valve has the effect of switching; and the adjusting type electric butterfly valve has the effect of adjusting the flow rate, which can accurately adjust the flow rate to thousand divisions. It is also a relatively expensive valve.
Storage method of electric butterfly valve:
1. The product should be stored in a dry and ventilated room, not in the open; the sealing ring should not be touched with oily substances to avoid aging.
Storage and delivery of electric butterfly valves:
1. Use stuffed caps at both ends of the diameter to prevent dust and rust and keep the passage clean.
2. Electric butterfly valves with a storage period of more than 18 months should be tested from the beginning before installation to ensure the integrity of the structure and function.
3. When placing the electric butterfly valve, ensure that the electric equipment is not kneaded and the terminal is damaged, and to prevent touching corrosive substances. When transferring, you should take care to avoid damaging electrical components and mechanical parts.
