Design principle of electric butterfly valve
The strain of electric butterfly valve mainly depends on the configuration of internal and external structures and the setting of materials.
Therefore, how the rubber function adapts to this change is the general principle of the overall formula design of rubber.
The first thing to consider when designing the compound formula is to control the function of hub materials;
The second is to start from the overall deformation structure, and put forward the mechanical function requirements of rubber bearing shear strain from the strain and compression deformation changes of various parts. The constant elongation stress of the material represents the stress strain property of the electric butterfly valve.
Therefore, the constant elongation stress is usually taken as the mechanical function index of the rubber compound. Carbon black is used as reinforcing material in the rubber compound of electric butterfly valve, which can improve its constant elongation stress, reduce the dynamic deformation and compression deformation of rubber compound under constant load, and reduce fever. Although the type of raw rubber used is different, the constant elongation stress in the rubber layer of each part should be fairly distributed.
