Patent KR-20200040707-A (KR)
Inventor: SONG JAE SEOP
IPC: F16L29/00
Filed: 2020-03-27
Abstract: The present invention provides a device which extends time for total destruction by fire by allowing water to flow in pipes of several upper floors of a building to allow water to flow to all floors to prevent total destruction of pipes in an early fire stage when a fire occurs since pipes of a building are lost in an early fire stage when a fire occurs to form holes between floors and rapidly spread the fire from lower floors to upper floors. Drain pipes, wastewater pipes, and rainwater pipes generally use PVC pipes, and thus are targets. When a fire occurs, a water supply system normally supplies water by an emergency generator. Therefore, an automatic electric opening/closing valve is installed immediately before a faucet mounted on the last outlet of a water supply pipe in an opened state or a water supply branch pipe (2) is installed immediately before the final faucet of each water supply pipe. The automatic electric opening/closing valve (3) operated by emergency generator power (7) supplied by the emergency generator is mounted in a closed state before a water supply faucet mounted on the end of the water supply branch pipe in an opened state. The electric opening/closing valve is automatically opened when a fire occurs and water flows through the water supply faucet (9) mounted in an opened state to allow water to flow in all pipes through a drain line, a wastewater line, and a rainwater line of upper floors to delay time for total destruction of pipes by heat of the fire to delay spreading of the fire from lower floors to upper floors in an early stage of the fire.
