The installation of the air powered electric butterfly valve must be subject to the vibration damping dynamic calculation, and the effect is the best
1. The installation of the air energy electric butterfly valve shall be subject to the calculation of the damping power, and shall not be carried out based on experience, so as to avoid resonance, low damping efficiency and other phenomena, resulting in losses.
2. In order to ensure the balance of equipment installation, the deformation of electric butterfly valve of damping butterfly valve shall be adjusted to be consistent; The electric butterfly valve of damping butterfly valve of the same series and model shall have uniform load; Deformation F=9.8 (P-P1)/k (mm);
3. During the specific installation, the electric butterfly valve of the butterfly valve shall be installed symmetrically for the symmetrical machine equipment;
4. While keeping the equipment stable, slightly move the position of the electric butterfly valve to make the deformation of each electric butterfly valve consistent;
5. For asymmetric machinery and equipment, if the centroid deviation of its center of gravity is large, different models of electric butterfly valves in the same series can be used, so that each electric butterfly valve has the same deformation under different loads;
6. For the bracing isolation system, the center of gravity of the vibration isolator shall coincide with the center of gravity of the equipment as much as possible.
