The sawtooth-shaped
noise reduction structure comprises a frame, and damping discs are evenly distributed in an inner cavity of the frame. Holes,
noise reduction channels and cavities are evenly distributed on the surface of the damping disc, the
noise reduction channels are designed in a
lightning shape and arranged in a double-layer mode, the holes and the cavities are communicated with the
noise reduction channels, U-shaped outlets are formed in the surfaces of the cavities, and the holes, the
noise reduction channels and the cavities are designed in a gradient increasing mode. After entering from the middle hole in the surface of the damping disc, fluid firstly enters the lower-layer double-layer
lightning type
noise reduction channel, the
special design can increase the fluid flowing
tortuosity degree, and
fluid pressure is effectively dispersed and reduced. And then the fluid flows into the cavity area to be further buffered and integrated, and then slowly flows out through the middle U-shaped outlet. The process is similar to a
waterfall from high to low and then flows out after being gathered in a smooth area, so that the
fluid pressure is gradually released, and the pressure-reducing and noise-reducing effects are achieved. Meanwhile, fluid is guided and protected through reasonable flow guide design, the flow speed is reduced, the
cavitation phenomenon caused by too high flow speed or sudden pressure change is avoided, and the valve body is well protected.
