摘要： 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.

摘要： The storm drain with water trap is installed in the opening of a storm or sewer drain to close off the underlying drain channels and residual water therein from the open air, thus preventing escape of mold, mosquitoes, and other hazards into the air. The device has an insert having an open top and bottom. A shallow water trap pan is suspended below the insert. In dry conditions, the water trap contains little water, the relatively light weight of the trap and contained water allowing it to be lifted by springs against the bottom of the insert to form a seal. When runoff water flows into the drain, the greater amount of water and its weight draws the insert downward, extending the springs and opening a gap between the lower edge of the insert and the water trap pan to allow the runoff water to flow therethrough.

摘要： A method and apparatus for admitting liquid from a draining surface into a drain conduit and for preventing discharge of waste gas from the drain conduit into the atmosphere in response to a higher pressure in the drain conduit than at the draining surface. The method and apparatus typically are for use draining floors, basements, roofs, countertops, exterior paved areas, and surfaces draining into line that could discharge waste gas back into the environment. The invention provides floor drain assemblies and check valves with good drainage performance with out the use of P or U-traps, and is particularly well suited for use when drainage occurs irregularly. Floor drains according to the invention comprise check valves adapted for disposition within floor drains, the check valves generally comprising spring-loaded stops, elastic diaphragms, or sheath valves. Check valves according to the invention are preferably installable in existing drain structures, and are easily removable.

摘要： The present disclosure provides an apparatus for preventing offensive odors for a drain port, the apparatus including: a plate that is formed in a plate shape so that it can be stably attached to the upper part of a drain manhole, and has a through hole formed in the center; a drain pipe that is connected to the through hole in the lower direction of the plate, is bent laterally from the lower direction, and has a shape in which an end is cut diagonally; and a shielding film that is connected by a hinge to the end of the drain pipe, is opened by rainwater or sewage discharged from the drain pipe, or is closed by a load. With such a configuration, a drain pipe is formed to guide rainwater, and a shielding film that is opened by rainwater or closed by a load is provided at the end part of the drain pipe, thereby preventing offensive odors generated from the drain port and also preventing insects from flowing into the drain port.

摘要： An odor-trap device (1) for in particular flushing-water-free sanitary devices, for example urinals, comprises an outflow element (2) with a sealing wall (3), and also comprises a sealing membrane (4), which is in sealing contact with the sealing wall (3) in a closure position and, in the presence of a liquid, such as urine, is pushed away from the sealing wall (3) from the closure position into an open position, as a result of which a gap (19) is formed between the sealing membrane (4) and sealing wall (3), it being possible for the liquid to be led away through said gap, and further comprises a mounting element (5) for mounting the sealing membrane (4) in relation to the sealing wall (3). The odor-trap device (1) is characterized in that the seating membrane (4) has a seating surface (6) which runs substantially parallel to the sealing wall (3), wherein the sealing surface (6) butts against the sealing wall (3) substantially with surface-area contact, or wherein the sealing surface (6) is spaced apart from the sealing wall (3) such that the liquid film which is present, at least in part, between the sealing wall (3) and the sealing surface (6) provides a force of adhesion between the sealing wall (3) and seating surface (6).

摘要： A valve allows for drainage of gases while preventing backflow of gases from a drainage system through the valve. A drain can have a first, sealed position in which a component of the valve seals an opening through the valve and a second, open position in which the component of the valve is separated from the opening to allow a fluid to drain through the valve. When the fluid has drained through, the component of the valve can return to the closed position. The valve can include a pressure relief conduit to help equalize pressure across the valve and permit unrestrained draining of fluid through the valve. The valve can be positioned in a roof vent and can include a guard.
