1. Principle of electric butterfly valve
Electric butterfly valve belongs to electric valve and electric regulating valve. It is a common product of fluid control and rough adjustment in the industry. Taichen electric butterfly valve is a valve that is driven by the electric actuator to drive the centerline stem to connect the valve disc to rotate 90 degrees. . Generally divided into two types: adjustment type and switch type. The electric butterfly valve has simple operation and small flow resistance. The thickness of the butterfly plate is the only resistance when the medium flows through the valve body. At the same time, the valve has good fluid control characteristics. Taichen electric butterfly valve is very suitable for large-diameter occasions. It is not only light in weight, short in structure, quick in opening and closing, and convenient in installation, especially the price of soft sealing structure is more economical. Nowadays, electric butterfly valve is an indispensable product in the water industry. Using high-quality materials, the service life can reach 50 million times.
Common electric butterfly valves include electric soft sealing butterfly valve and electric bidirectional hard sealing butterfly valve. Taichen electric soft sealing butterfly valve adopts wafer connection, ductile iron material, and rubber sealing structure is the cheapest control product at present, and its working performance is also excellent. very stable. The electric two-way hard sealing butterfly valve produced by Taichen Valve Factory adopts the triple eccentric metal sealing structure to achieve the two-way flow of the medium, and at the same time, it can achieve the effect of zero leakage and long service life.

2. Classification of electric butterfly valve:
Electric Wafer Butterfly Valve: It is suitable for regulating flow and intercepting media in food, chemical, petroleum, electric power, papermaking, water supply and drainage, and gas pipelines with temperature ≤80～120℃.
Electric soft-sealed butterfly valve: suitable for lining, not only the valve seat, but also the butterfly plate can be lined. At present, it has reached the sealing and full lining technology. It can achieve the effect of not polluting the medium as a sanitary valve, which is unreachable by ordinary ball valves. sex.
Electric hard-sealed butterfly valve: the use of surfacing hard alloy makes the sealing surface high strength, good hardness, wear resistance, and can reach a life of more than 5,000 times.
Electric flanged butterfly valve: It is designed with three-dimensional eccentricity principle, so that the space movement trajectory of the sealing surface is idealized. Temperature, wear resistance, etc. are reliably guaranteed.
Electric regulating butterfly valve: The electric regulating butterfly valve is powered by 220V AC power supply, accepts 0~10mA or 4~20mA standard signal, drives the valve opening corresponding to this operation signal, and achieves the purpose of regulating medium pressure, flow, and temperature. The structure is simple, Easy to operate. It is especially suitable for ventilation systems and the regulation of media containing suspended particles.
Electric rubber-lined butterfly valve: suitable for use in fresh water, sea water, salt, weak alkali, weak acid, natural gas, air, steam, oil, food and other media.
Electric ventilation butterfly valve: The electric ventilation butterfly valve is made of the same material as the valve body into a sealing ring, which is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and adjustment of medium flow.
Electric telescopic butterfly valve: The telescopic butterfly valve is mainly used for regulating and intercepting the flow, compensating for the thermal expansion and cold contraction caused by the temperature difference of the pipeline, and also provides convenience for installation, replacement and maintenance of the valve.
