The present invention has its application in the industry of manufacturing bathroom furniture, specifically in the industry of manufacturing urinals or dry urinals, that is, urinals or dry urinals that do not drag waste through water. The advantage of our valve with respect to the valves of the prior art, is that our water seal does not require dragging water; it is the urine itself that achieves the seal without the odor developed by the urine of the water seal returning to the users' space; it incorporates an additional seal of spheres the use of consumables in the product, such as sealing oil, scent pads, among others. Structurally, our invention consists of an outlet valve, in a waterless urinal, towards the drainage, to prevent the return of foul odors, characterized by comprising a hydraulic trap formed by a tank where a certain volume of urine is formed, a funnel that discharges the new urine into the bottom of the tank, and an upper valve where the seal is carried out by one or two spheres in their respective seats.

A hybrid flushing system for water free urinals is presented with a housing having a wall portion forming a cavity for receiving a cartridge. The housing also includes a flushing fluid inlet portion for receiving a flushing fluid and a flushing fluid directing portion configured to direct the flushing fluid. A cartridge for installation into a housing is presented, including a cartridge wall, a flushing fluid receiving portion and a flushing fluid directing portion to direct flushing fluid received to any portion to clean areas of the housing, the cartridge, and connected plumbing. Steps for cleaning a hybrid flushing system are presented with an act of directing a flushing fluid into an area, where the area is one of a cartridge for a hybrid flushing system, a housing for a hybrid flushing system, and a plumbing system connected with the hybrid flushing system.

The inventive subject matter provides apparatus, systems, and methods in which a valve mechanism is incorporated into a drain to reduce or prevent noise or food fragments from emitting out of an operating garbage disposal. The valve mechanism is generally a skirt valve biased to a closed position, disposed within a housing, and inserted into a drain such that food or fluid passes through the valve into a downstream grinding device. Once the food or fluid has passed through the valve, the valve closes.

Provided is a drain trap that allows easy maintenance, yet has high durability with ability to prevent condensation. The drain trap includes a bottomed cylindrical main body portion 5 having a lateral wall 51 on which a receiving pipe portion 2 for receiving liquid and a discharge pipe portion 3 for discharging the liquid are formed, an attachable/detachable partitioning body 1 for partitioning an inside space 4 of the main body portion 5 into a reservoir space 7 and a discharge space 8, a lid portion 6 for closing the inside space 4 of the main body portion 5 and a sealing case 9 surrounding, under a sealed state, at least a portion of an outer surface of the main body portion 5 in which the reservoir space 7 is formed. An air gap 91 is formed between the sealing case 9 and the main body portion 5. The sealing case 9 and the main body portion 5 are formed transparent. The lid portion 6 is attachable/detachable when the sealing case 9 is attached to the main body portion 5.

Described is a resilient fluid control valve assembly. The resilient fluid control valve assembly includes a cartridge housing having an upper portion and a lower portion. The upper portion is formed to reside above a drain opening, while the lower portion is formed to reside within the drain opening. The resilient fluid control valve assembly further includes a resilient fluid control valve positioned within the cartridge housing. The resilient fluid control valve has a valve body portion and a sealing portion. When positioned within the cartridge housing, a portion of the valve body portion resides above the drain opening, and a portion of the sealing portion resides within the drain opening.
