A Way of Regulating the Fluid Inflow into a Pressure Collector- Pipeline Under the Presence of the Input Flow

The inflow of fluid into collector-pipelines (CPs) increases along the CP according to non-linear law. It is found that under the presence of transit flow at the input of the pressure CP the latter in its initial segment distributes, but not collects, the fluid. A method of regulating the fluid inflow into CP has been invented. According to this method the fluid distribution is transformed into its inflow into the CP. It is proposed that kinetic energy of transit stream which inflows into the CP at its beginning be used for constricting of the fluid stream in inlet nozzle sites. It is recommended to use local constricting inserts. There forms a closed torus – shaped space between the outer surface of the elastic constricting insert and the inner surface of the CP wall. Into this space, the pressure available in the stream in the site in front of the preceding inlet nozzle is supplied. The force of this pressure displaces walls of the elastic constricting insert in radial direction towards the CP axis. The pressure in the site of the inlet nozzle becomes less than that outside the CP. The fluid outflow out of the CP stops and changes to inflow into the CP. This takes place in each inlet nozzle in the site of which an elastic constricting insert is placed.
