In order to further meet the needs of the development of modern buildings, the technical improvement, design and manufacture of WGD type damping butterfly valve composite shock absorber have been carried out. The combination of damping butterfly valve and damping pad has overcome its shortcomings. It has the advantages of compound vibration isolation and noise reduction, low natural frequency and good vibration isolation effect. It is superior to the sound transmission of isolated solids, especially the sound transmission of isolated high-frequency impact
