Benefits of Damped Electric Butterfly Valves
The electric butterfly valve of damping butterfly valve has a strong ability of working compliance. It can also work normally at minus 40 degrees or minus 110 degrees, which is a working state that ordinary electric butterfly valves cannot reach. It has a very significant effect in active valve, passive vibration isolation or shock vibration, and can also effectively block the sound transmission of solids. It has achieved very obvious results in reducing noise, isolating vibration, renovating vibration pollution and maintaining the environment.
The damping data on the surface of the metal structure can effectively restrain the vibration of the structure on the natural frequency, and can greatly reduce the structural noise. For example, coating damping materials on the inner walls of passenger cabins of trains, cars and aircraft can effectively reduce noise and improve the environment. The wheels of metro trams use five constrained damping layers, and the noise drops from 114dB (A) to 89dB (A). The damping data quality accounts for 4.2% of the wheel mass. The noise of the saw blade drops from 95dB (A) to 81dB (A) after the constrained damping layer is applied.
