The electric butterfly valve is a relatively simple one among all types of electric butterfly valves. Its main material is a small amount of metal or other materials. But don't underestimate this small element. Its effect is no less than that of other electric butterfly valves. It is generally used on some vehicles. Electric butterfly valve is also a kind of vibration damping and isolation element commonly used in engineering.
According to the stress, the electric butterfly valve can be divided into compression type, shear type, compression shear composite type, etc. The biggest advantage of the electric butterfly valve is that it has large damping, good vibration reduction effect near the resonance frequency, and is suitable for vibration isolation in vertical, horizontal and rotating directions. The stiffness has a wide range of options. Compared with steel butterfly valve, its disadvantage is that its vibration isolation performance is easily affected by temperature, and its performance is poor when used at low temperature. The static compression is low and the natural frequency is higher than 5Hz, so this electric butterfly valve is not suitable for equipment with low interference frequency (natural frequency lower than 5Hz) and heavy weight.
Many people do not expect that the engine will have something to do with the electric butterfly valve. In fact, as long as you remember, where there is vibration, there can be an electric butterfly valve, but this electric butterfly valve may be an electric butterfly valve, it may be an electric butterfly valve, or even other types of electric butterfly valves. It is obvious that they exist to reduce vibration and noise, which can kill two birds with one stone. Then why should the engine use the electric butterfly valve? It is very simple. As just said, where there is vibration, there is an electric butterfly valve. After the engine starts, there will be high frequency vibration and loud sound. At this time, vibration damping must be used to reduce the vibration sense and noise. In fact, this is to make people who are operating the engine more comfortable, and also to protect the engine from vibration, which will reduce its life. Take a car for example. If the engine of the car does not have an electric butterfly valve, you will feel very bumpy when driving on a flat road. And the noise is also very loud. This is the advantage of electric butterfly valve.
