What are the advantages and disadvantages of electric butterfly valve? What are the characteristics??
What are the advantages and disadvantages of our electric butterfly valve? Let me introduce you to this little editor!
1. It can be made into products with various shapes and different hardness, with good elasticity and sufficient strength;
2. It can make the natural frequency of the vibration isolation system lower and have higher damping;
3. No matter under tension, compression, shear and modification, the deformation is relatively large.
Compared with electric butterfly valve of metal butterfly valve, its main defects are:
1. Its natural frequency is difficult to achieve below 5Hz;
2. Its ability to resist environmental pollution and temperature change is weak, and its service life is short.
characteristic:
The reason why vibration isolation pads are widely used is that they have durable high elasticity and good performance of vibration isolation, shock isolation and sound insulation; The appearance and pressing are convenient, and the shape and size can be freely selected to meet the requirements of stiffness and strength; It has certain damping performance and can absorb mechanical energy, especially the absorption of high-frequency vibration energy; Because the material and metal surface can be firmly bonded, it is not only easy to manufacture and install, but also can apply multi-layer superposition to reduce stiffness, change its frequency range, and the price is low.
Of course, like the electric butterfly valve, the vibration isolation pad also has its weaknesses, such as being vulnerable to temperature, oil quality, ozone, sunlight and chemical solvent corrosion, and its performance changes, aging and relaxation. Therefore, its service life is generally about 8 years, but without more than 10 years of corrosion.
The performance of the vibration isolation pad is not only related to the shape and formula of the pad,? It is also related to the hardness of, which is high in hardness, large in stiffness, large in bearing capacity, low in hardness, low in stiffness, and small in bearing capacity. The hardness of some damping pads can be divided into 40 ℃, 60 ℃ and 90 ℃. Be careful when selecting them.
