摘要： In a washdown flush toilet, a water discharge trap conduit includes: an inlet pipe part connected to a bowl part receiving waste; a trap ascending pipe part connected to the inlet pipe part and forming an ascending flow channel; and a trap descending pipe part connected to the trap ascending pipe part and forming a descending flow channel. With regard to a cross section perpendicular to a flow direction of the ascending flow channel, a portion on a downstream side of the ascending flow channel is provided with an enlarged part having a cross section area larger than that on an upstream side of the ascending flow channel. A downstream end of the ascending flow channel and/or an upstream side of the descending flow channel is provided with a shrunk part having a cross section area smaller than that on the upstream side of the ascending flow channel.

摘要： A plumbing trap assembly for plumbing a condensation drain line into a sewer line includes a P-trap that is plumbed into a drain line of a sink. The P-trap has an inlet, an outlet and a lower bend that is positioned between the inlet and the outlet. The inlet is fluidly coupled to a drain of the sink and the outlet is fluidly coupled to a sewer line servicing the sink such that the lower bend forms a trap for sewer gasses. A condensation inlet is integrated into the P-trap thereby facilitating the condensation inlet to be fluidly coupled to a condensation drain line of an air conditioning unit. In this way condensation from the air conditioning unit can be drained into the sewer line which services the sink.

摘要： A joint device for drain pipes comprises a structural tube made of a rigid material and providing structural integrity to the joint device. The structural tube defines at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network. An annular seal of resilient sealing material is integrally connected to an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device.

摘要： A drain coupler includes a drain coupler body having a lower opening and an upper opening. A pliable seal is carried by or adjacent the upper opening, the pliable seal operable to form a water-tight seal about an exterior of a metallic throat section of a drain. Coupler engagement structure is carried by the drain coupler adjacent the upper opening of the drain coupler body. Cap engagement structure is carried by a cap. The cap engagement structure and the coupler engagement structure cooperatively enable removable engagement of the cap over the upper opening of the drain coupler body to temporarily cover the upper opening of the drain coupler. The cap is removable to allow insertion of the metallic throat section in the pliable seal.

摘要： The object of the present invention is to provide a washdown flush toilet which can maintain effective waste discharging performance even with a relatively smaller amount of flush water.
The present invention is a washdown flush toilet including: a bowl part configured to receive waste, and a water discharge trap conduit connected to a lower portion of the bowl part. The water discharge trap conduit includes: an inlet pipe part whose one end is continuous or connected to the lower portion of the bowl part; a trap ascending pipe part whose one end is continuous or connected to the other end of the inlet pipe part and which forms an ascending flow channel; and a trap descending pipe part whose one end is continuous or connected to the other end of the trap ascending pipe part and which forms a descending flow channel. With regard to a cross section perpendicular to a flow direction of the ascending flow channel, a portion on a downstream side of the ascending flow channel is provided with an enlarged part which has a cross section area larger than that on an upstream side of the ascending flow channel. A downstream end of the ascending flow channel and/or an upstream side of the descending flow channel is provided with a shrunk part which has a cross section area smaller than that on the upstream side of the ascending flow channel.

摘要： A water drain management apparatus used in clinical facility (43) or other facility includes a manifold plumbing fitting (32, 272, 384). The fitting includes a plurality of drain outlet connections for water discharge devices (40, 42, 222, 226, 230, 234). Such water discharge devices may include devices such as autoclaves, sterilizers, cleaners, washers, filters, humidifiers, condensing devices and other devices used in the facility. A plurality of drain fitting openings in the body of the fitting are connectable to respective water discharge devices, and openings that are not utilized are closable with plugs. Some manifold fittings (272, 344, 384, 482) include an air gap opening (288, 360, 392, 530). These configurations provide an air gap that prevents contamination due to back flow of water within the fitting reaching water discharge devices or the body inlet of the manifold fitting.

摘要： A pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.

摘要： A contamination unit for isolating a building from contamination of a sewer is disclosed. The contamination unit includes a housing with an inlet and an outlet, a trap assembly, and a fluid trigger. The inlet is in fluid communication with a fluid source, plumbing equipment, and/or condensating equipment to receive fluid. The housing has a reservoir to collect the fluid therein and to define a reservoir portion of a contamination barrier about the outlet. The trap assembly includes a trap conduit between the outlet and the sewer that is shaped to collect the fluid therein and define a trap portion of the contamination barrier. The fluid trigger is positionable about the housing to selectively release the fluid through the inlet and into the reservoir of the housing whereby the fluid in the contamination barrier is maintained to prevent the contamination from passing from the sewer into the building.
