Sewer flooding control system
Abstract
Abstract AN IMPROVED SEWER FLOODING CONTROL SYSTEM UTILIZED TO PREVENT THE FLOODING OF A BUILDING BASEMENT BECAUSE OF A BACKUP IN THE BUILDING SEWER OR THE SURGING OF SEWAGE IN THE SEWER. THE IMPROVED SEWER FLOODING CONTROL SYSTEM IS MOUNTED BELOW THE FLOOR LEVEL OF A BASEMENT TO BE PROTECTED AND IS ACTUATED BY THE PRESENCE OF SEWER FLOODING CONDITIONS IN THE SEWER. THE IMPROVED SYSTEM ALSO PROVIDES NOVEL MERANS FOR PREVENTING FLOODING OR DAMAGE AS A RESULT OF SURGING SEWAGE BOTH IN THE BASEMENT AS WELL AS WITHIN THE SYSTEM, AND ALSO PROVIDES NOVEL GUIDE MEANS FOR GUIDING A GLOAT AND PREVENTING DAMAGE FROM SURGING. WHEN FLOODING CONDITIONS EXIST, A FLOAT MEBER RISES WITH THE LVEL OF THE SEWAGE, AND IN TURN, CAUSES A VALVE TO CLOSE IN THE SEWER PIPE, THERBY PREVENTING ANY FLOW OF SEWAGE THROUGH THE PIPE. WHEN FLOODING CONDITIONS SUBSIDE, THE FLOAT IS CORRESPONDINGLY LOWERED WITH THE LEVEL OF SEWAGE AND THE VALVE IS OPENED.
