入防止装置。(1) A three-way pipe opening/closing valve installed in the water transmission pipeline, the inlet side connected to the upstream pipeline section of the opening/closing valve of the water transmission pipeline, and the outlet side connected to the opening/closing actuator of the pipe and line-to-line closing valve. It consists of a master valve, and a water pressure acting pipe which has one end connected to the inlet pipe of the master valve and the other end connected to the switching actuating part of the master valve and which causes the pipe outlet water pressure to act on the master valve switching actuating part, The opening/closing device for the pipeline opening/closing valve opens the pipeline opening/closing valve when the water pressure taken out from the water supply pipeline is equal to or higher than a predetermined water pressure, and closes the pipeline opening/closing valve by spring force when the water pressure falls below a predetermined water pressure. The three-way master valve applies this water pressure to the valve opening/closing actuator when the water pressure at the pipe outlet is above a predetermined water pressure, and when the water pressure at the outlet falls below the predetermined water pressure. A water supply pipe outflow/inflow prevention device characterized by being a snap-action three-way valve that switches to release water pressure acting on a valve opening/closing device to the drain pipe side.
