Abstract
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.
Claims15
An apparatus for continuously controlling fluid flow in a conduit, comprising:
- a) sensor means, for detecting the level of fluid in this conduit;
- b) conduit sealing means, for releasably sealing in fluid tight fashion a section of this conduit;
- c) main power means, for actuating said sealing means;
- and
- d) control means, sensitive to said sensors means and actuating said main power means responsively to a conduit fluid level reaching beyond a threshold value;
- wherein the performance of said control means is independent of the speed of the fluid flow in the conduit.
A method for operating an apparatus for continuously controlling fluid flow in a conduit, the apparatus of the type comprising sensor means for detecting levels of fluid in this conduit, conduit sealing means for releasably sealing in fluid tight fashion a section of this conduit, main power means for actuating said sealing means, and control means, sensitive to said sensors means and actuating said main power means responsively to a conduit fluid level reaching beyond a threshold value so that the performance of said control means is independent of the speed of the fluid flow in the conduit;
- wherein the method comprises the following steps:
- a) said sensor means sensing a fluid level beyond said threshold value;
- b) said control means analysing data coming from the sensors means;
- and
- c) said control means actuating said conduit sealing means responsively to said data.
A method for installing and releasably locking a valve apparatus inside a clean-out duct of a sewer conduit, the valve apparatus for continuously controlling fluid flow in the conduit, the apparatus including:
- a) sensor means, for detecting the level of fluid in this conduit;
- b) conduit sealing means, for releasably sealing in fluid tight fashion a section of this conduit;
- c) main power means, for actuating said sealing means;
- and d) control means, sensitive to said sensors means and actuating said main power means responsively to a conduit fluid level reaching beyond a threshold value;
- wherein the performance of said control means is independent of the speed of the fluid flow in the conduit, the apparatus further including a discoid support member releasably mounted inside the clean-out duct, a hang screw rod assisting in the positioning of said discoid support system in said clean-out duct, said sealing means being an inflatable bladder, said inflatable bladder in deflated configuration movable to a set position inside the clean-out duct, and further including retaining clips to prevent accidental release of said apparatus from its said set position, wherein said method comprises the following steps:
- a) said hang screw rod moving the said apparatus inside said clean-out duct;
- and
- b) said inflatable bladder in deflated configuration emitting a sound cue emitted through said rod, indicating said deflated bladder has reached its said set position inside the clean-out duct.
