Variety and application range of pneumatic ball valve
Classification of shock absorber:
High elasticity is a kind of durable performance with good vibration absorption, vibration isolation and sound insulation; Inhibit beauty and convenience, and freely choose shapes and sizes to meet the required strength and stiffness; Damping performance is certain, which can absorb mechanical energy. High frequency vibration energy absorption is particularly prominent because of this, it is widely used in the needs of various vibration equipment. This article mainly introduces the classification of shock absorbers.
At present, there are many kinds of shock absorbers on the market, which can be easily designed into many types according to different application conditions. According to the classification specifications of shock absorbers, and according to the classification and specifications of shock absorbers, the classification of products is valuable for readers.
At present, shock absorbers are widely used in various machinery, automobiles, railway locomotives, water transportation, aircraft and other fields, and play an increasingly important role. It is no exaggeration to say that dampers are required in all central areas requiring valves and isolation. According to different application conditions, industrial pneumatic ball valves can be designed into many types.
The shock absorber is widely used due to its effective application of the following characteristics:
It has high elasticity and viscoelasticity. Compared with steel materials, it has small elastic deformation and elastic modulus; The impact stiffness is greater than the dynamic stiffness, dynamic stiffness and static stiffness ratio, which is conducive to reducing the impact deformation and dynamic deformation. It is an elliptical delay line of stress-strain curve, and its area is equal to all the vibration periods of thermal vibration (damping); The shape adjusted by the formula design can be freely selected, and can be adjusted by the hardness formula design to meet the different directions of the required stiffness and strength. There is no certain shape. By adjusting the formula composition to control the hardness in all directions, the required strength and stiffness of the internal friction can be met. The damping effect is good, which is conducive to the interpenetrating resonance, high-frequency vibration and noise attenuation. Compared with the elastic modulus of metal, it can avoid large sliding elastic deformation, low maintenance quality, and easy disassembly and installation. The impact stiffness is higher than the static stiffness and dynamic stiffness, which is conducive to impact deformation.
These non waiting advantages of dampers have played a great role in promoting their universal application. Especially for the automotive industry, automotive pneumatic ball valve plays an important role.
