REINFORCEMENT VALVE FOR PREVENTING BACKFLOW IN DRAIN TRAP
The present invention relates to a reinforcement valve for preventing a backflow in a drain trap, which can be additionally installed inside a drain trap, which can perform the air backflow phenomenon pre-contributing to the quality of the quality of the drain trap and to performance improvement thereof, and which always has the best backflow blocking function regardless of a strong air pressure generated inside the drain trap and any change thereof. A conventional drain trap has a water gathering portion (20) formed beneath a trap body (10); an inflow-side drain tube (30) and a discharged-side drain tube (40) are connected to one side and the other side thereof, respectively, such that draining occurs therethrough; a blocking membrane (60) is configured between the water inflow opening (31) And the water discharge opening (41); and a water drain hole (51) is bored between the blocking membrane (60) and the bottom surface inside the trap body (10). Th e present invention is configured by installing a backflow-preventing reinforcement valve (100) on the front side of the blocking membrane (60), in which the water drain hole (51) is formed, such that, when water is drained from the corresponding household, the same is automatically opened by the water pressure, thereby allowing water to drain, and, when water draining is completed, the same is automatically closed by self-weight, thereby guaranteeing, through control, that, even if a strong air flow is introduced into the drain trap, no backflow of air occurs.
