Introduction to performance of damping pneumatic butterfly valve
Damping is one of the three basic elements of handling shock. However, its performance parameters are difficult to test, and its shock absorption effect is difficult to predict. Therefore, in general, the first way to stop the shock absorption control is to add mass, change stiffness, add isolators or dynamic shock absorbers, while in some special places, it is necessary to use the damping method. For example, for some pneumatic butterfly valves with thin plate structure, which make people feel helpless, damping method can achieve satisfactory results.
Damping pneumatic butterfly valve has the following benefits: it can stop the oscillation peak value under the resonance frequency; Reduce the transmission of oscillation along the structure; Falling tectonic noise. It is worth pointing out that damping is the most useful for suppressing oscillations in the resonant region, but it is less effective in the non resonant region.
The damping tension spring shock absorption has two advantages: the low frequency of the tension spring shock absorber and the large damping of the rubber shock absorber. By separating the advantages of the two points, the phenomenon of amplitude surge when the tension spring shock absorber resonates is eliminated, and the natural frequency comparison of the rubber shock absorber is handled.
Damping pneumatic butterfly valve is mainly completed by using the inherent characteristics of damping data and the reasonable planning of damping structure. Damping data is a new type of special data developed in the past decade, which has gained more and more effects in many fields. It is a kind of polymer data, which has high damping characteristics when converting modes, that is, it can consume energy when deformation, and can stop the peak value of structural oscillation in a wide frequency range.

Nonmetallic compensator (fabric compensator, fiber fabric compensator)
Usage: Fabric compensator (fiber fabric compensator) can compensate axial and angular directions, and has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and shock absorption. It is especially suitable for hot air pipes and soot pipes.
Connection mode:
① Flange connection type
② Receiving connection
Fabric compensator (fabric compensator) type:
① Compound form
② Angular type
③ Use of square non-metallic compensator
It is widely used in iron and steel plants, smelters, petrochemical plants, thermal power plants, cement plants, atomic power plants and other equipment such as flue gas desulfurization, dust removal equipment, air heating, flow assisted blowing and other equipment at the entrance and exit. It is much better than the metal expansion joint, so it is deeply criticized by users and vigorously promoted.
