Product details

The effect is to reduce the aperture at the appropriate place in the pipe, and when the liquid passes through the shrinking mouth, the flow beam will become thinner or shrink. The minimum cross section of the flow bundle appears in the downstream of the actual shrinkage mouth, which is called the shrinkage section. At the contractive section, the velocity is the maximum, and the increase of velocity is accompanied by the great decrease of pressure at the contractive section. As the stream beam expands into a larger area, the velocity decreases and the pressure increases, but the downstream pressure does not fully return to the upstream pressure, due to greater internal turbulence and energy expenditure.
