Fluid circuit breakage protector

The invention discloses a fluid circuit breakage protector. The fluid circuit breakage protector is characterized by comprising a water inlet tube (18), a flow inductor (9), a valve (8), a valve electric actuator (17) and a control terminal (20), wherein the flow inductor (9) and the water inlet tube (18) are connected by threads; the flow inductor (9) is electrically connected to a control terminal (20) through a wire; the valve (8) and the water inlet tube (18) are in threaded connection; the water inlet tube (8) and the valve electric actuator (17) are in nested connection; and the valve electric actuator (17) is connected to a control terminal (20) through an electric wire. According to the fluid circuit breakage protector disclosed by the invention, the control panel and the control terminal can be in fixed power line connection, and can also be separately arranged but in wireless connection for fluid cut-off operation.
