Application and characteristics of pneumatic butterfly valve
The shock absorber is widely used, with durable high elasticity and good performance of shock absorption, shock isolation and sound insulation. Its 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 data can be firmly bonded to the metal surface, it is not only easy to manufacture the device, but also can reduce the stiffness by applying multi-layer superposition, change its frequency range, and the price is low.
The performance of the shock absorber is related to the shape, formula and hardness of the pad. It has high hardness, large stiffness, large bearing capacity, low hardness, low stiffness and small bearing capacity. The hardness of some damping pads is divided into 40 ℃, and the introduction of ZD damping ball valve damper
The damping ball valve has the double advantages of low frequency and large damping of the steel ball valve damper, and eliminates the inherent resonance amplitude of the steel ball valve.
Damping damper (pneumatic butterfly valve with damping ball valve) has a wide load range and strong compliance. It can simultaneously produce obvious effects on active vibration isolation, passive vibration isolation and impact vibration isolation. It is a versatile vibration isolation product with multiple functions, suitable for the working environment of - 20 ℃ - 80 ℃. Its natural frequency is 1 within the normal working load range. The damping ratio is 0. 065 is an ideal damping product for air conditioners, thermostats, fans, cooling towers, refrigeration units, compressors, pumps and other airborne equipment.
