Anti reflux Valve, Automatic closing, Driving for Networks of low pressure Liquid, with the solid and / or contaminated sediments in suspension

摘要

The objective in developing this inventionIs to produce a device for automatically Controlling Automatic counter flows that can occur in the pipes for the Transport of Liquids Li driven by Gravity,Usually with little or no hydrostatic pressure and can give Solids or sediment transport in suspen - Sion.In this purpose, has been an essential condition that the internal section of the Val Vula remain constantly Open,Tar to prevent interference with the sediment content and facilitate the Movement of the Fluids that Roll freely, but at the time of submission of a COUNTERFLOWThere is an automatic closure that prevents access of the liquid returned.It is important to note that the solution here - Stands creates a radically different System employees currently, because until now, any element used for this purpose.Need to ACCUMULATE sufficient pressure to open com - doors, which at Rest remain Shut - das; Likewise,The system allows the optimal Evacuation of solids and sediments may contain Liquids.Among the many applications that can be given to this Invention are Networks of Driv - ing Water, usually roll on the bottom of the pipe.Without different pressure to give a slope of 1 or 1 1 / 2% and transporting solids and sediments in suspension, being exposed to kickbacks.Either to increase the level of the canals or rivers which Drain, or in any place where a tamponade in termedio, accidental, or ex assigned process Liquids,Saturate the capacity of the network and its contents to the Overflow - lateral Branch.
