In oneembodiment the fitting comprises of a receptacle body, a floatation device, and atop cover. The fitting is configured to allow passage of liquid in one direction whilerestricting the flow of gases in opposite direction.[0027] ​In one embodiment the fitting is retrofitted into an existing urinal. Inanother embodiment a urinal fixture/pan integrated with the fitting is provided.[0028] ​The following description is set forth for purpose of explanation in order toprovide an understanding of the invention. However, it is apparent that one skilledin the art will recognize that embodiments of the present invention, some of which4
are described below, may be incorporated into a number of different plumbingsystems and devices. Structures shown below in the diagram are illustrative ofexemplary embodiments of the invention and are meant to avoid obscuring theinvention.[0029] ​Reference in the specification to “one embodiment”, “in one embodiment”or “an embodiment” etc. means that a particular feature, structure, characteristic, orfunction described in connection with the embodiment is included in at least oneembodiment of the invention. The appearances of the phrase “in one embodiment”in various places in the specification are not necessarily all referring to the sameembodiment.A. Overview[0030] Fig​. ​1​ shows the diagram of the sanitary plumbing fitting as per anembodiment herein. As shown in Fig. 2, the fitting ​100​ may be fitted into a urinal panor a sanitary fixture ​102​ where it connects to a trap or a drain ​104​.[0031] Fig. 2​ shows the blown out diagram of the sanitary plumbing fitting as per anembodiment herein. The fitting comprises of a main receptacle body ​140​ that maybe fitted into the exit of a urinal pan (​102 of Fig. 1​). The receptacle body ​140​ may beelongated and may have tubular structure. Other shapes may be provided. Afloatation device ​120​ may be inserted into the receptacle body such that thefloatation device may move along atleast some part of the length of the receptaclebody.​​A top cover ​110 ​may be fitted on top of the receptacle body after inserting thefloatation device. In a typical usage scenario, the sanitary plumbing fitting may beplaced in a urinal pan. Upon urination in the pan or a fixture the urine flows downfrom the top cover along the length of the receptacle body. Upon reaching the partof the receptacle body the floatation device achieves sufficient buoyancy allowingfloatation thereof. Once the urine is drained the floatation device settles down onthe bottom surface of the receptacle body hence blocking the flow of gases upwardsfrom the bottom of the receptacle body. Even though various materials may be used5
for construction of the sanitary plumbing fitting, use of stainless steel improves thechemical resistance towards various chemicals used in cleaning and maintenance.B. Receptacle body[0032] Fig​. ​3​ shows a receptacle body of the sanitary plumbing fitting as per anembodiment herein. The receptacle body ​140​ may be coupled to the urinal panwhich further connects to the drain pipe. The receptacle body may have anelongated with top end ​146​ allowing placement of the top cover ​110​, while thebottom end ​145​ may have bent surface ​144​ which allows for quick passage of liquidand prevents the system from getting choked in the presence of solid particles. Inone embodiment, the bent surface ​144​ may be chamfered from the inside and/oroutside. In another embodiment, the bent surface ​144​ may be filletted from theinside and/or outside, thereby forming a hole over which the float ​120​ may rest. Thefloatation device/the float may rest over the hole by keeping the dimension of thehole smaller than the smallest cross sectional area The elongated portion maycomprise of threading on the outer surface ​148​ thereof, for secure fixing of thefitting into the exit of a urinal pan. The slope and filleted surface also increases theflow rate of the liquid and prevents the system getting locked due to vacuumgenerated in the pipeline. Further, the special slope at the bottom also makes thefloatation device stand straight axially thereby increasing the chances of thefloatation device sealing the passage during the times when the urine is not beingdrained.C. floatation device[0033] Fig​. ​4a​ and ​Fig. 4b​ illustrates the floatation device ​120​ of the sanitaryplumbing fitting as per an embodiment herein. The floatation device may bedesigned insertable into the receptacle body.[0034] ​The floatation device acts as a sealant and a one way passage which allowsthe liquids to pass into the drain pipe but does not allow the odour causing gases tocome back by sealing the passage in the receptacle body. The surface of the6
the floatation device and allow to drain them. New design of cap makes it easy toremove it during maintenance and cleaning thereby reducing the time and effort.The slope / fillet inside the receptacle body where the float sits, solves the problemof sticking of the float to the vertical walls of the receptacle body which in turn usedto create a gap. The slope / Fillet provided now makes the float slides to its actualposition and helps in complete sealing of the opening / drain hole.[0047] ​The system, method and the fitting described herein in some exemplaryembodiments may minimize the use of water may save anything between 50000 to150000 liters per pan per annum of water.[0048] ​The foregoing description of the invention has been described for purposesof clarity and understanding. It is not intended to limit the invention to the preciseform disclosed. Various modifications may be possible within the scope andequivalence of the claims appended.
