Background

The throttling pressure reducing sleeve is a substance for reducing the flow rate and the pressure of fluid, is usually arranged in a pipeline to prolong the service life of the pipeline, and has the function of reducing the aperture at a proper position of the pipeline, so that when liquid passes through a necking, a flow beam can be thinned or shrunk. The smallest cross section of the flow stream occurs downstream of the actual throat, called the throat. At the flow reduction cross-section, the flow velocity is at its maximum, and an increase in flow velocity is accompanied by a large decrease in pressure at the flow reduction cross-section. As the stream expands into a larger area, the velocity decreases and the pressure increases, but the downstream pressure does not fully return to the upstream pressure as a result of the greater internal turbulence and energy consumption.

The conventional throttling orifice plate is an integral orifice plate, a plurality of holes are processed on the plate, fluid media flow into the throttling orifice plate from a plurality of throttling orifice plate branch inlets of the throttling orifice plate and flow out from a throttling orifice plate branch outlet through a throttling orifice of the throttling orifice plate, the throttling orifice plate only has weak pressure reduction effect on the media fluid in the process, the fluid media flowing out of the throttling orifice plate still have larger energy, and particularly, when the fluid media are high-pressure and high-speed, the phenomena of vaporization, flash evaporation, vibration and high decibel noise hazard of pipeline system equipment (valves) are easy to generate.
