Definitions

  • This invention relates to devices for managing fluid flow within fluid drainage systems, and more particularly to junction devices for fluid drainage systems.
  • FIG. 1 shows a conventional junction 10 commonly used in rain water down pipe systems.
  • the conventional junction 10 has a down pipe 12 and a connecting horizontal pipe 14 that is joined in a perpendicular orientation.
  • water flows and clings along the wall of the pipe in a spiral direction indicated by arrows 30, while air flows in the opposite direction indicated by arrow 20 in the center of the pipe.
  • Water also flows along connecting horizontal pipe 14 in the direction indicated by arrow 32.
  • the vertical down pipe 12 is typically fluidly connected to the main drainage sources such as the roof top of a building.
  • the horizontal branches typically fluidly connect the secondary drainage sources such as floor outlets, floor wastes, balconies, planter drainage, or the like as shown in FIG. 2 to the vertical down pipe 12.
  • a water plug 34 is formed in the down pipe 12 preventing the flow of air 20 causing the air to back flow 22.
  • Backflow occurs when the clear air passage in an open channel of a rain water down pipe system is completely filled with water and forms water plugs, thus preventing air from escaping upwards through the center of the pipe. Instead, air escapes through the side branches 14 causing backflow. Escaping air from the branches is known as positive air flow, whereas air being drawn into the pipe from the branches is known as negative air flow. Significant positive and negative pressures which may form inside the pipes during water flow contributes to backflow.
  • siphonic rain water down pipe SRWDP
  • siphonic drainage systems siphonic drainage systems
  • the main drainage is completely separate from the drainage of secondary drainage such as floor outlets, floor wastes, balconies, planter drainage and the like.
  • the main drainage is not fluidly connected with the secondary drainage because siphonic systems are drainage systems where the pipes are filled with water and contain no air and exhibit full bore water flow.
  • pipes commonly used in siphonic drainage systems are 1/3 of the size of pipes commonly used in conventional gravity rain water drain pipe systems (non-siphonic drainage systems).
  • the down pipe is typically 2" (50mm), and in non-siphonic drainage systems the down pipe is typically has a gauge of 6" (150mm).
  • the siphonic outlets feeding the down pipes in the siphonic drainage system are specially designed to prevent air from entering the system, and the pipe gauge or diameter of the down pipe in the siphonic drainage system connected to the siphonic outlets is chosen to be relatively smaller than in non-siphonic drainage systems to ensure that the pipe is completely filled with water. It is not recommended to connect a non-siphonic pipe or junction to a siphonic system as it will introduce air into the siphonic system and prevent full bore flow in the siphonic system thereby reducing the drainage capacity of the siphonic system.
  • US 3894302 describes a device for joining horizontal lines from one or more plumbing fixtures, such as toilet, to a vertical stack.
  • US 1582845 describes drainage fittings, in particular, for hanging battery wall toilets.
  • US 3376897 describes a pipe branch piece of a pressure line, which has one pipe leg of large diameter and at least two pipe legs of smaller diameter.
  • US 3346887 describes an aerating connector fitting for use in a sanitary drainage system.
  • JP11071794 discloses a collecting pipe for waste water for preventing variation of inside pressure in a pipe of one-pipe type drainage piping.
  • JP2001026957 discloses a drain pipe joint provided with a horizontal branch pipe connection part.
  • a fluid junction device according to Claim 1.
  • a fluid junction device for managing a first fluid flowing from at least two sources and a second fluid from at least one source, the second fluid capable of a negative pressure flow and a positive pressure flow, the device comprising the technical features of independent claim 1.
  • a drainage system comprising a plurality of devices according to claim 1, wherein the output of an upper device in fluid communication with the first port of the lower device.
  • the first port of the upper device is optionally fluidly connected to a siphonic outlet, and each device comprises an escape for the second fluid in either a positive pressure flow or negative pressure flow through the second port of each device.
  • FIG. 3 shows a cross-sectional view of an anti-backflow junction device 100 in operation in accordance with an embodiment of the invention.
  • FIG. 4 shows the cross-sectional view of the anti-backflow junction device 100 of FIG. 3 with perspective view showing a side port 142 exposed on the second port 104.
  • the cross-sections of FIG. 3 and FIG. 4 are taken along the line A-A shown in FIG. 5A of a top view of the anti-backflow junction.
  • the anti-backflow junction device comprises a body 108 with a cavity or passages having first port 102, a second port 104 and a third port 106.
  • the first port and the second port are in fluid communication with fluid sources (not shown) which may be draining rain water collected from rooftops, balconies, floor wastes, floor outlets, planter drainage and the like.
  • the body 108 is configured with a lip or diverter 112 in the wall that defines a nozzle 110 with the sidewall of the body of the junction device along the wall of the first port and the third port opposite the second port.
  • a section of the side wall of the second port forms provides as gradual descent, an escape cut away 114, of the branch to the third port. This cut away section 114 maintains the diameter of the pipe size to ensure downward water flow exit from the second port to the third port.
  • a support 136 is provided between the first port and the second port to provide added structural support for the second port and make the junction device rigid, however, it will be appreciated that such support may not be necessary or other means of support may be envisaged.
  • the diverter 112 is shown in more detail in the top view of the junction device of FIG. 5A and the cross-sectional views of FIG. 6A and 6B taken at different cross-sections of the anti-backflow junction device 100 shown in FIG. 4 .
  • the diverter 112 is a protrusion, ramp, channel, lip, bump, latch, ledge, or the like that extends from wall or within the surface of the first port.
  • the diverter is integral with the side wall extending from the mouth of the first port such that the surface of the side wall is continuous with smooth surfaces.
  • the diverter may be formed as protrusion, ramp, channel, lip, bump, latch, ledge, or the like having smooth and angled configuration.
  • the diverter is integral with the side wall.

  • the bottom length is the distance from point 113 to point 115 around the head of the nozzle in a cross-section (not shown) including the point 124 shown in FIG. 4 .
  • the depth of the diverter extends from a first point 122 and a second point 124 as shown in FIG. 4 .
  • the diverter is sculpted as shown by channel 117, and the resulting diverter width 119 is shown that changes along the length of the diverter.
  • Diverter width is defined by the horizontal distance, relative the central axis of the first port, from point 124 to dashed line 128 in FIG. 4 . More specifically, diverter width is the distance from the surface of the diverter that is exposed to the water to the first port wall of the pipe as shown in FIG. 6A and FIG. 4 .
  • the dashed line 128 is an extension of the sidewall 126 of the first port by which the width of the diverter 112 may be seen from dashed line to the surface of the diverter exposed to the interior of the junction device 100.
  • the diverter width is the distance along a radial line diverging from the central axis 180 of the first port from the edge of the ledge of the diverter 112 to the side wall extension as shown as dashed line 128 in FIG. 4 of the opening of the first port taken along a desired cross section as shown in FIG. 6A .
  • the depth of the diverter is the vertical distance, relative the central axis of the first port, along the surface of the diverter forming the interior surface of the pipe that extends from point 122 and 124 shown in FIG. 4 .
  • the length of the diverter is shown in FIG. 5A and extends from the first point 113 to a second point 115.
  • the diverter has configuration such that in operation, the diverter 112 manages to divert the flow of the downward spiraling water entering the mouth of the first port 102 as indicated by arrows, and concentrates the flow of water against the opposite wall 111 of the second port 104 and third port 106, forming a water plug 134 at the first port proximate the diverter, between the diverter in the side wall 111 of the junction device 100 opposite the diverter 112.
  • the diverter 112 in this embodiment has a sloping, gradient or ramping orientation with respect to the side wall of the first port.
  • the diverter width 119 varies along the length of the diverter 112, and remains constant for the majority of the length at each cross section along the length, however, near the point 113,115 the diverter width is tapered. It will be appreciated that the width of the diverter may vary along either the depth or length or both or remain uniform. The length and/or depth of the diverter may also vary or be uniform along the depth and/or length, respectively. Some variations are shown and discussed in detail below with reference to FIG. 9A-12B .
  • the configuration of the side wall 111 and the diverter 112 form a nozzle 110.
  • the diverter 112 is in a position having the orientation where the first port cross-sectional area is reduced at the tip, at point 124, of the diverter forming the nozzle head.
  • the diverter 112 is designed to reduce the cross-sectional area of the first port within the shortest width and yet has the least resistance to the fluid flow so as to maximize fluid capacity. This desired function is achieved by the shape and angle of the diverter 112 shown.
  • the ratio of distances of the cross-sectional openings of the nozzle head 150, from the opposite wall of the first port 111 to the tip 124 of the nozzle head shown in FIG.
  • the ratio to achieve is a balance between the maximum capacity of the anti-backflow junction device and the effectiveness of the anti-backflow junction device. For example, the ratio for percentage of reduction may be from approximately 10% to 25%. It will be appreciated that the ratio of the opening of the first port and the opening of the nozzle head may vary for specific applications, and may be less than 10% or more than 25%.
  • junction of the second port 104 with the first port 102 to the third port 106 as shown is a graduated junction with smooth edges and curves with escape cut away section 114.
  • Another function of an embodiment of second port section 114 besides allowing air to escape is to maintain the pipe diameter of the second port. Maintaining the pipe diameter in the second port also helps to prevent blockages by foreign items and debris such as leaves, twigs, soil and the like at the second port. This also allows the overall size of the anti-backflow junction device 100 as small and compact as possible.
  • FIG. 16 shows a flow diagram of a method 400 in accordance with an embodiment of the invention.
  • the flow of water 130 from the first source 402 is channeled or diverted by diverter 112 in the side wall which forms the nozzle 110 that increases the velocity of the flow of water 132 downstream of the nozzle 110 and out third port 106.
  • the air flow 120 is left clear for the air to escape 406 through the second port 104.
  • the configuration ensures a controlled situation at every junction within the body of the device.
  • the nozzle 110 formed by the diverter 112 at the junction ensures the formation of the water plug 134 and therefore ensures that the pressure build up at above the nozzle.
  • the forming of the pressure above the nozzle 110 creates a pressure jet which passes through the nozzle at increased velocity. Pressure is released after the nozzle 110.
  • the pressure builds and increases again above the next downstream nozzle. This situation is repeated at every junction and may be predicated and controlled.
  • the pressure jet that is formed by the nozzle 110 may cause a high velocity pressure jet that accelerates the water beyond the junction, thereby ensuring a clear air passage at the junction.
  • the anti-backflow fitting works in both negative and positive pressure which is a phenomenon that occurs with water and air flowing in pipes and drainage systems. In most cases the air inside the anti-backflow fitting 100 is forced downwards through the next nozzle together with water traveling at high velocity. In such cases the high velocity pressure jet causes the junction to be under negative pressure. In cases where the discharge is submerged or where the nozzle do not allow sufficient amount of air discharging downwards, the junction of the anti-backflow fitting is under positive pressure. Air escapes through the clear air passage created by the nozzle.
  • the configuration of the anti-backflow fitting 100 in accordance with an embodiment of the invention ensures a clear air passage is maintained at each junction of the anti-backflow fitting, such that water is being prevented from being brought up through the passage by the downward pressure jet.
  • the device 100 having this configuration provides predictability and controllability.
  • the flow capacity of the anti-backflow fitting can be determined by physical testing. Empirical testing has shown that a flow rate of 20 I/s without any backflow, whereas conventional junctions experience backflow at as little as 2-3 l/s. Due to the principle that each junction forces the formation and release of pressure, there are no unpredictable pressure fluctuations at the junctions.
  • the action of the nozzle configuration 110 increases the velocity of the fluid to jet flush the junction and the entire system. This jet action enables the self-cleansing of the pipe interior and minimizes blockages.
  • the pressurized system allows a significantly higher flow rate through a pipe as compared to the conventional gravity system.
  • the junction may be fitted for pipes of any number of dimensions and cross-sections.
  • the ports of the junction may be adapted for a gauge of 3" (75mm) for the first port and 2" (50mm) for the second port, 4" (100mm) for the first port and 3" (75mm) for the second port, and the like.

  • the ports may be adapted to receive the same or different sized pipes.
  • the first port may be adapted to receive larger dimensioned pipe than the second port and/or the third port.
  • the third port may have a dimension that is equal to the first port and/or second port, or may have a different gauge than the first and second ports.
  • the pipes may be tubular and the cross-section of the pipe may be circular or any number of other cross-sections, such as rectangular, square, oval or the like.
  • the thickness of the pipe walls may be any thickness conventionally used, for example, about 2-3mm.

  • FIG. 8 shows a front elevation perspective view of the anti-backflow junction having the second port of the junction with multiple ports in accordance with an embodiment of the invention.
  • FIG. 8 specifically shows at multiple ports at the second port 140 having ports 104, 142 and 144. It will be appreciated that any of the ports may be configured with one, two or multiple ports. Each of the ports may be in fluid connection with the same source or different sources of fluid.
  • connection between the ports may be made with a pipe, connecting pipe, another junction or fitting, or the like.
