特徴としたポンプ圧送給水用凍結防止装置。 In a water supply piping system that is pumped by a pump, a first state is provided between a branch pipe branching from the water supply pipe of the water supply piping system and a drainage pipe, and a first state in which the branch pipe and the drainage pipe are cut off, and a first state in which the branch pipe and the drainage pipe are An electric valve opening/closing valve that switches the piping to the second state where it communicates, a summer side that maintains the branch piping and drainage piping in the first state, and a summer side that switches the branch piping and drainage piping to the first state when the pump is stopped. transition to the second state,
The valve opening/closing control device includes a summer/winter switching switch that selects the winter side to return to and hold the first state after a certain period of time set by a timer has elapsed, and has a built-in drive source for the electric valve opening/closing valve. When the summer/winter selector switch is set to the winter side, each time the pump motor is confirmed to have stopped,
It consists of a pump motor stop detection unit that is electrically connected so that the summer/winter selector switch is turned on to the winter side again. If the pump motor stops with the winter selector switch set to the winter side, the electric valve opening/closing valve will open, and after a certain period of time set by the timer, it will shut off again and hold. Features: Freeze prevention device for pump pressure water supply.
