Performance introduction of damping electric butterfly valve
Damping is one of the three basic elements of handling shock. However, its performance parameters are difficult to test, and the valve effect is difficult to predict. Therefore, in general, the first way to stop the valve operation is to add mass, change stiffness, add isolators or dynamic shock absorbers, etc., while in some special places, the damping method is required. For example, some electric butterfly valves with thin plate structure, which make people feel helpless, can obtain satisfactory results by adopting damping method.
Damping electric 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 valve has two advantages: the low frequency of the tension spring damper and the large damping of the damper. By separating the advantages of the two points, the phenomenon of amplitude surge when the tension spring damper resonates is eliminated, and the natural frequency of the damper is also handled.
Damping electric 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.
