摘要： A backflow prevention apparatus is provided with a check valve and a float-type backflow prevention valve, these being installed in this order as one proceeds from upstream to downstream. The check valve comprises a valve seat; a valve member that closes the valve at the valve seat due to an upwardly directed restoring force; and a restoring force exerting member that exerts an upwardly directed restoring force on the valve member. The float-type backflow prevention valve comprises an annular valve seat; a float that rises in accompaniment to a rise in a water level of wastewater to close the valve at the annular valve seat; a guide member that guides movement of the float in a vertical direction; and a constraining member that constrains a lowermost position to which the float can move.

摘要： A waterless trap for use in a drain assembly includes flow enhancing features to promote the vortex water flow of water received in the trap, an improved sealing arrangement to enhance the seal between a seal member and the housing to inhibit sewer gas leaks from an attached drain pipe by maintaining an evaporation barrier that assists in retaining water in a corresponding p-trap, and a plurality of air passages can allow the trap seal to open with ease when the drain pipe is pressurized. These features may be used in combination with one another or may be independently employed.

摘要： A sealing valve for a floor drain has three principal components held together by an actuating bolt. When tightened, the operating bolt compresses a central elastomeric member between a base portion of a first flanged member and a flat compression plate sealing off peripheral passageways as well as those extending through the flanged member and elastomeric member preventing incursion into the residence by sewage, sewer gases, bugs, rodents and other pests.

摘要： An odour-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 odour-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： The present invention relates to an odor trap intended for installing in a pipe to a drain. The odor trap comprises a tubular element (1) and a blocking means (2). The blocking means (2) makes it possible to close the pipe but is shiftable by fluid flowing in the odor trap in order to allow said fluid to pass, and in order, when the fluid has passed, to return to the position which closes the pipe. To achieve an odor trap in which the blocking means is well protected against undesirable external influences and the configuration of the odor trap is such that it is easy to fit, the tubular element (1) is made of inelastic material and the separate blocking means (2) disposed in the tubular element is made of elastically deformable material, said blocking means comprising a fitting portion (6) removably connected to a fitting portion (7) of the tubular element, and a blocking portion (8) which is integral via a peripheral edge (9) with the fitting portion of the blocking means, and which, when in the position which closes the flow cross-section of the pipe, abuts, via the peripheral edge, fluidtightly against the inside of the tubular element and which, possibly with parts of the fitting portion of the blocking means, is to a varying degree shiftable by the fluid to allow the fluid to pass.

摘要： A closure device for a drain pipeline includes an outer sleeve, an inner sleeve mounted in the outer sleeve, and a closure member. The outer sleeve is adapted to be installed between a drain of a sink or washbasin and a drainpipe. A flow port is defined in the inner sleeve. The closure member is movably supported in the inner sleeve in a vertical direction. The closure member is normally biased by a spring to close the flow port so as to block odor from flowing into an indoor space, and the closure member is moved downwards to open the flow port when draining water into the outer sleeve.
