Wiring of electric shutter butterfly valve It can directly control different types of vibrations with different frequencies and regular swings, but these controls largely limit the normal thermal displacement of the pipeline that should be carried out. Therefore, when designing, it is necessary to consider the additional forces generated between the electric butterfly valve of the butterfly valve and the pipeline, which mainly rely on the role of the butterfly valve to resist the impact, When the butterfly valve rebounds after shock absorption, it will also have a resistance effect
