How does the valve hand wheel act to control the noise of the valve within a reasonable range? In the previous section, we addressed the issue of regulating the noise of the valve. From a technical point of view, today we will say that the noise control range should be below 85 dB in the fluid. Under the influence of power noise, the maximum value can reach 100dB. In this case, the effect is very serious, so we must strictly control the noise range.
Then this is related to the design of the regulating valve itself. Of course, this is closely related to the various components such as the valve handwheel and the valve core. Considering its noise factors, it is mainly to respond to fluid dynamic noise. Since the liquid obstruction flow can easily cause flash evaporation and cavitation, and flash and cavitation generate noise, controlling the noise requires a way to control the flash and cavitation of the obstructed flow. This requires more professional knowledge, technical support customer service Q:454584030, not a single sentence can be made clear.
The design criteria of the valve hand wheel is to control the overall pressure, and the technical personnel professionally analyzes the scale, angle, and material of the design. The production side controls strictly and cannot ignore any details.
