Automatic flow shut-off system |
摘要 |
An automatic flow shut-off unit for shutting off water to an appliance (e.g. commode) when a leak or overflow occurs. The unit includes an outer housing having a ball valve mounted thereon wherein the valve is connected between the water supply and the appliance. A tripper unit is mounted in the outer housing and has a plunger therein. The valve is connected to the plunger by a length of actuation material (e.g. flexible cable). A compression spring is positioned in the tripper unit to normally bias the plunger downwards. A cartridge having a water reactive material (e.g. commercially-available toilet paper) thereon is removably mounted in the outer housing wherein the water reactive material when dry supports the plunger in a cocked position but which will quickly weaken and disintegrate upon contact with water.
