What is the principle of air spring pneumatic butterfly valve?
The vibration and noise are almost always around us, affecting people's life and work, and sometimes causing great damage to buildings. The relationship between vibration and noise is very close. Because the essence of sound is vibration, it is necessary to conduct some research on vibration first to control vibration and noise. The reciprocating motion of an object near the balance position is called the vibration of an object. The vibration of a machine or other mechanism is transmitted from its surface to the air, and the other part is transmitted from the foundation of the machine or the objects connected to the machine through solids. The air vibration of 20HZ-2000HZ can be felt by people.
Vibration isolation principle of air spring: air spring is airbag. The basic structure is to fill a retractable closed container with compressed air, which can play the role of a spring by using the nature that the air recovers after being compressed. The so-called vibration isolation means that the vibrating machine is separated from other objects by an elastic or damping device to reduce the interference of the vibration source to other objects.
Shock absorbing airbag is mainly used for shock absorption. At present, automobile shock absorption and anti-collision airbags are the most widely used.

Introduction to Color of Pneumatic Butterfly Valves
About the introduction of the color of pneumatic butterfly valve products, are all stainless steel products bright in color? Neither.
Some customers think that the color of stainless steel pneumatic butterfly valve should be relatively bright. In fact, we will find that some types of stainless steel pneumatic butterfly valves are snow white or even dark silver gray. For example, 316L stainless steel corrugated pipe is not bright in snow white color.
I once thought that the bright color of 304 stainless steel pneumatic butterfly valve is the way to distinguish 304 from 201 pneumatic butterfly valve made of ordinary material. Later, I learned that some 201 pneumatic butterfly valves have bright colors, while some 304 pneumatic butterfly valves have dark colors. In fact, the bright color of stainless steel pneumatic butterfly valves is mainly due to the use of electroplating or polishing, while some 304 stainless steel pneumatic butterfly valves will reduce their luster due to manufacturing processes, such as pickling, but the acid and alkali resistance will not be affected.
