It is an interesting electric butterfly valve that can block vibration and reduce noise, deal with vibration hazards and protect the environment
Characteristic analysis of electric butterfly valve and electric butterfly valve of damping butterfly valve Electric butterfly valve and electric butterfly valve of butterfly valve are two different electric butterfly valves with considerable difference, but their function is to reduce vibration. When choosing electric butterfly valve, many people do not know whether to buy electric butterfly valve or electric butterfly valve of butterfly valve
So Shanghai Dongfeng Environmental Protection Co., Ltd. shares the differences between them: the characteristics of electric butterfly valve: 1. It has high elasticity and viscoelasticity; 2. Compared with steel material, the elastic deformation is very large and the elastic modulus is very small; 3. The impact stiffness of is greater than the dynamic stiffness, and the dynamic stiffness is greater than the static stiffness, which is conducive to reducing the impact deformation and dynamic deformation; 4. The stress-strain curve is an elliptical hysteresis line, and its area is equal to the vibration energy (damping) converted into heat in each vibration cycle, which can be adjusted through formula design; 5. Is incompressible material (Poisson's ratio is 0.5); 6. The shape can be freely selected, and the hardness can be adjusted through formula design to meet the requirements of stiffness and strength in different directions; 7. Its natural frequency is difficult to reach below 5HZ; 8. Its resistance to environment and high temperature changes is weak, and its life is short; 9. No sliding part
