Abstract
The utility model discloses a water-outage automatic shutoff valve, belonging to the field of valves. The utility model solves the problem that water runs out through the valve after the water supply is resumed in case of forgetting to close the valve when finding a water outage after opening the valve. The water-outage automatic shutoff valve comprises a pipe with a water inlet and a water outlet. A valve seat and a valve spool matched with the valve seat are arranged between the water inlet and the water outlet. A valve spool limiting mechanism and a valve spool automatic resetting mechanism are arranged on the pipe. In case of water outage, if the valve is opened, the limiting mechanism falls off to limit the position of the valve spool, the valve spool automatic resetting mechanism acts and the valve spool is reset and works cooperatively with the valve seat to close the internal passage in the pipe. The utility model is suitable for water supply pipelines.
