Water supply control assembly with automatic shut-off and duty cycle reset |
摘要 |
A water supply control assembly is disclosed for cutting off the supply of water to a house or building in the event of excessive water consumption. In one embodiment, a valve is secured to a distribution conduit in fluid communication with a pressurized source of fluid. A water flow sensing unit is secured between the inlet port and the flow discharge port. A magnet is mounted therein to a displaceable member and moved into and out of magnetic field coupling proximity to a timing reed switch in response to the onset and termination of pressurized water flow through the water flow sensing unit. A controller is coupled to the timing reed switch in order to actuate the valve to a water shut-off condition in response to the continuous flow of pressurized water for an elapsed flow time in excess of a preset duty cycle limit.
