Definitions

  • the present invention relates to the field of liquid flows, especially in sewage systems, and more particularly relates to a device for adjusting or adjusting the level of liquid flowing in a pipe, as well as a distribution box. liquid equipped with such a device.
  • the current non-collective sanitation installations generally comprise at least a first purification unit composed of a sealed pit in which the suspended solids are decanted, possibly supplemented with a biological purification reactor and a clarifier, and then a final purification unit including the spreading of pre-purified effluents into the soil, in particular by means of infiltration trenches, sand filters or spreading bed.
  • the non-collective sanitation plants generally comprise, downstream of the purification units of said effluents from the houses, a view of distribution of the pre-purified effluents to a multiplicity of pipes (hereinafter referred to as downstream pipes) arranged in parallel , which are extended by perforated pipes or trenches for the percolation of said pre-purified effluents through layers of draining materials such as gravel or sand disposed in the surrounding soil, close to the sanitation installation .
  • downstream pipes a multiplicity of pipes
  • the ends of the downstream pipes are generally positioned so as to be all arranged on the same horizontal level, in order to distribute equitably in each of them the pre-purified effluent or effluents discharging into said view via a or several pipes, hereinafter called upstream pipe (s).
  • upstream pipe s
  • Part of the installation is then "off", while the other party receives all the effluents, which sometimes causes a congestion or overflow of the percolation zone, and / or an anticipated clogging of the downstream pipeline, which can no longer fulfill its role of final purification.
  • a solution to this problem has recently been provided by a device for raising the level of passage of the liquid in the ends of the downstream pipes, the device being formed of a shutter member with a V-shaped cross section that can be adapted to the said end. of pipeline.
  • a V-slot shape of the passage section significantly reduces the (flow rate) of the liquid flow in the closed pipe, compared to adjacent downstream pipes.
  • the narrowed section portion i.e., the lower portion of the V
  • the present invention aims to overcome the aforementioned drawbacks by proposing a device for adjusting the level of liquid flowing in a non-vertical positioning pipe which is simple, adjustable positioning and slightly reducing the flow rate downstream in said pipe .
  • the present invention proposes a device for adjusting the level of liquid flowing in a pipe with non-vertical positioning (horizontal or inclined pipe), characterized in that it comprises a disk, closing said pipe transversely, and having a hollow central portion which constitutes the liquid passage section, the edges of the recess (of said passage section) affecting the shape of a spiral portion, so as to create a closure section for the flow of the fluid, whose height is variable according to the orientation of the spiral edges of the passage section.
  • Such a device allows, thanks to the spiral shape of the passage section of the liquid, an easy flow thereof without risk of clogging.
  • a fine adjustment of the positioning of the spiral, that is to say the level of the passage section is also possible due to the rotation of the disc around the axis of the pipe, that is to say according to the adjusting the orientation of the spiral edges of the device.
  • the device according to the invention preferably comprises a connection sleeve of the disk to said pipe, preferably at the end of said pipe.
  • the connection sleeve may be conical in shape for a good fit with the pipe and a possible adaptation to different pipe diameters.
  • the device according to the invention may comprise tabs or tongues for fixing to said pipe, projecting on a face of the disk, (face facing the pipe) curved adapted to be housed inside the pipe for the purpose of keep the disc pressed against the end of the pipe.
  • These tabs can be bent and flexible.
  • these gripping means may be elements, of ergot type, protruding from the face of the disc.
  • these elements, lug-type may protrude from the face of the disk opposite to the face cooperating with the pipe / connection sleeve.
  • the gripping means may be gripping notches formed at the periphery of the disc, opposite the recessed central portion.
  • the device for adjusting the liquid level according to the invention is not fixed by permanently at the end of the pipe but can be adjusted again over time if the conditions require it (modification of the flatness of the ground, elevation of level between the different pipes ).
  • the present invention also relates to an assembly comprising a non-vertical positioning pipe and a device for adjusting the level of liquid flowing in said pipe as described above.
  • the present invention also relates to a liquid distribution box receiving the ends of at least one upstream pipe (incoming liquid) and at least two downstream pipes (liquid discharge) of substantially different diameters and / or arranged at heights substantially different in said distribution box, characterized in that at least one end of said downstream pipes is equipped with the device as described above, so as to adjust the level of liquid in the pipe or pipes and equalize the distribution of liquid in all downstream pipes by varying the angular position of the disk inducing the setting of the shutter threshold.
  • Such a liquid distribution box may, for example, constitute a view of the distribution of effluents from a sanitation installation, such as a non-collective sanitation installation.
  • the device 1 for adjusting the liquid level consists of two main parts, namely a disc portion 2 of substantially flat shape and a sleeve portion 3 extending substantially orthogonally to the rear face of the disc 2.
  • the disc 2 has a hollow central portion whose peripheral edges have the shape of a spiral 4 with a recess 5.
  • the conical sleeve portion 3 of the device 1 according to the invention is intended for connecting the disk 2 to a pipe 6.
  • the rear face of the disk of the device is adapted to the end of the pipe 6 to close at least a peripheral portion of its passage section.
  • the level of liquid that can flow from and to said pipe 6 is adjusted by the height h of the spiral edge of the disk at the bottom of it.
  • the front face of the disc is provided with a gripping pin 11 located for example, as visible on the figure 2 in the lower part of the disk at the right of the recess 5 (that is to say corresponding to the intermediate position of the level of the passage of the liquid) and can also be used as a reference for the adjustment of the angular position of each of the disks of a distribution look.
  • Such a device for regulating the flow of liquid in a pipe is quite appropriate in a liquid distribution box such as an effluent distribution port as shown schematically on the figure 4 .
  • a said distribution box 7 receives an upstream pipe 8 (arrival of the effluent) and a multiplicity of downstream pipes 9 in which the effluent must be distributed equitably with a view to its evacuation, for example, in percolation devices on a bed sand.
  • Each of the downstream pipes 9 may be equipped, at its end opening into the distribution box, a liquid level adjustment device comprising a disc with a spiral passage section according to the invention.
  • the angular positioning of the disk and therefore of the spiral makes it possible to adjust the shutter threshold, that is to say the threshold of passage of the liquid in said pipe.
  • FIG. 5 An example of setting the disk in two adjacent pipes of different heights is shown schematically on the figure 5 .
  • the left pipe is located at a lower level than the right pipe.
  • the angular position of the adjustment device 1 is displaced by rotation of the disk so that the height h of the bottom of the left spiral is greater than at height h 'of the right spiral.
  • the connecting sleeve or the fastening tongues are preferably made of material with the disc (monoblock device).
  • Possible materials are metallic materials, or polymeric materials, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyurethane (PUR), phenoplasts (PF), unsaturated polyesters (PET) or polyacetal (POM), without this list being limiting.
  • Polyvinyl chloride is preferred, being particularly resistant to hydrogen sulfide, frequently encountered in the pipes.
  • the liquid level adjustment device is entirely appropriate in effluent distribution manholes of a non-collective sewerage installation requiring the distribution of the purified effluents in a multiplicity of pipes for the purpose of controlling the effluent. infiltration of the effluents into the soil but can be used for any liquid distribution box in pipes for which a fine adjustment of the passage and the flow of the liquid.
