Fluid backup preventing system and method of use thereof

摘要

An apparatus for continuously controlling fluid flow in a sewer conduit, comprising: a) moisture sensors detecting levels of fluid in this conduit; b) an inflatable bladder, mounted in the sewer conduit for releasably sealing in fluid tight fashion a section of this conduit; an air compressor, for inflating the bladder; and a control box including a CPU, sensitive to the moisture sensor and actuating the air compressor responsively to conduit fluid level conditions reaching beyond a preset threshold value. The performance of the apparatus is independent of the speed of fluid flow in the sewer conduit.

主权项

1. An apparatus for use in a conduit in which a fluid flows to block the conduit upon detection of a problem condition for the fluid, comprising:
an inflatable bladder adapted to be mounted in a section of an inner cavity of the conduit, the inflatable bladder being inflatable/deflatable between a deflated inoperative condition and an operative inflated condition in which the bladder is inflated for sealingly closing the conduit section; at least one sensor assembly comprising a pair of wires connected to a sensor adapted to detect the problem condition of the fluid wherein the sensor is positioned in the conduit on at least one side of the inflatable bladder, and beyond a contact area between the inflatable bladder and the conduit, the side being that related to the problem condition of the fluid; a pressure system in fluid communication with the inflatable bladder to inflate the bladder to the operative inflated condition, and to deflate the bladder to its inoperable condition; a processor unit for actuating the pressure system when the problem condition is detected by the at least one sensor, and for subsequently deflating the bladder when the problem condition is no longer detected; and wherein said sensor assembly is at least partially covering and overlapping the inflatable bladder.
