Application and characteristics of rubber pneumatic butterfly valve
Rubber shock absorber is widely used. It has 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 rubber material can be firmly bonded to the metal surface, it is not only easy to manufacture the device, but also can apply multi-layer superposition to reduce the stiffness, change the frequency range, and the price is low.
The performance of rubber shock absorber is related to the shape, formula and hardness of the rubber pad. It has high hardness, high stiffness, large bearing capacity, low hardness, low stiffness and small bearing capacity. The hardness of some rubber shock absorbers is divided into 40 ℃, ZD damping spring shock absorber
Damping spring has the double advantages of low frequency and large damping of steel spring shock absorber to eliminate the inherent resonance amplitude of steel spring.
Damping damper (pneumatic butterfly valve with damping spring) 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, suitable for working environment of - 20 ℃ - 80 ℃. Its natural frequency within the normal working load range is 1. 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.

Three characteristics of non-metallic corrugated contraction joint
Our company specially introduces non-metallic corrugated contraction joints to a wide range of users. Literally, the main material of the tube body forming the contraction joint is fiber fabric or other special non-metallic materials.
Product characteristics:
(1) Compensated thermal shrinkage: non-metallic contraction joints can provide larger multi-dimensional direction compensation in a smaller size range.
(2) Compensating device error: because system error is unavoidable in pipeline connection, non-metallic contraction joint can better eliminate device error.
(3) Noise elimination and vibration isolation: fiber fabrics and thermal insulation cotton can absorb sound and isolate vibration transmission, which can effectively reduce boiler
