Definitions

  • the invention relates to drain trap devices intended to trap solid materials from wastewaters streaming out of sanitary and/or plumbing and/or industrial waste stream equipment, such as a sink, bath, shower tray, industrial drains, etc.
  • Such drain trap devices most often involve a siphon portion, providing a water seal against reflux of odours, which retains solid materials in its lower part.
  • This type of drain trap devices is well know in the art. These devices require occasional draining and/or cleaning to remove deposits of solid materials (such as, in particular, hair parts, often agglomerated with soap and greasy remains, small objects accidentally fallen in the drain, etc.) from the siphon and maintain the proper operation of plumbing installation.
  • the invention thus provides a drain trap device for sanitary and/or plumbing equipment, comprising an inlet portion to receive fluids from the sanitary and/or plumbing equipment and an outlet portion to discharge fluids into a plumbing system, said inlet and outlet portion being connected via a underlying siphon portion, in which drain trap device the siphon portion comprises a draining valve.
  • said draining valve comprises in particular a ball valve mechanism.
  • valve mechanisms is well known in the art; it is in particular often used in heating installations.
  • ball valve mechanisms can be used in carrying out the present invention, with the ball portion made of PVC, tetrafluoroethylene (such as "TEFLON"), polypropylene, brass, ceramic material, etc., and with seals made of tetrafluoroethylene, ceramic material, etc.
  • Preferred ball valve mechanisms involve the combinations of a brass ball with tetrafluoroethylene seals or of a ceramic ball with ceramic seals.
  • the ball valve mechanism ideally constitutes the bottom part of the siphon portion of the drain trap.
  • the ball valve mechanism may however have to be positioned extending laterally with respect to the siphon portion of the drain trap, such as for instance in the case of bath or shower tray siphons, where the siphon portion is often placed too near a floor surface to position the ball valve as the bottom of the siphon.
  • the drain trap device comprises a siphon portion with a inner tubular section extending into a lower part of the siphon portion to provide a fluid seal mechanism (a construction well known, per se, in conventional drain traps), whereas the ball valve mechanism comprises one hemispheric valve part which can be rotated from a closed position to an open position, and vice versa, without interfering with said inner tubular section.
  • the ball valve may be provided with any type of handle (fixed or removable) in function of the practical or aesthetic criteria set by the user.
  • Figure 1 shows a drain trap device according to the invention, designated in its totality by reference numeral 1;
  • the upper part (above line A) of the drain trap device according to the invention is generally similar to most drain trap devices well known in the art, involving a siphon system, and is only represented on the drawings for a proper understanding of the essence of the invention (as incorporated in the lower part of the drain trap device), i.e. the fact that the drain trap device comprises a draining valve, preferably a ball valve mechanism;
  • the bottom part (below line A) of the drain trap device according to the invention designated by reference numeral 2 in the drawings, comprises a rotating handle 3 for actuating the draining valve of the drain trap.
  • the upper part of the drain trap device 1 comprises an inlet 4 to the siphon system, for receiving waste waters from a sanitary or plumbing equipment (not represented) and an outlet 5 for discharging the waste waters.
  • the inlet 4 of the drain trap can be connected to the sanitary or plumbing equipment through connecting means 5, well known per se.
  • the pipe 4 constituting the inlet of the drain trap, can slide up and down within a tubular section (plastic pipe) 7, to allow height adjustment of the inlet 4 with respect to the outlet 5.
  • the inlet pipe 4 and the tubular section / pipe 7 (comprising a bevelled, thickened upper extremity, not visible in the drawings, but well known per se in the art) are connected to each other in a water tight manner by means of a tightening screw ring 8, well known per se.
  • the bottom part of the siphon generally constitutes a downwardly convex closing lid, which is screwed in the upper part.
  • the bottom part 2 of the device screwed in the upper part, essentially comprises a ball valve mechanism, provided and adapted in such a way that operating the ball valve does not interfere with the lower extremity of said pipe 7 (constituting the inner tubular section of the siphon providing the fluid seal mechanism).
  • the actual ball valve 9, made of brass with an outer layer of chromium or nickel, of the ball valve mechanism is maintained in said bottom part 2 by means of a first, fixed, internal abutment ring 10 providing support for a first "TEFLON" seal ring 11, and by means of a second internally screwed abutment ring 12 providing support for a second "TEFLON" seal ring 13.
  • the ball valve of the specific embodiment of the invention represented in the drawings involves a valve ball, which is partly cut-away on one side of the ball (called here the "hemispheric" ball part of the ball valve), in the way more clearly represented in figures 3 and 5 of the drawings.
  • This distinguishing feature with respect to the more conventional ball valve shape allows the operation of the ball valve mechanism without interference with the inner pipe 7, even if the pipe 7 reaches far into the bottom part of the siphon in order to provide an optimal fluid seal.
  • the bottom portion of the pipe 7 is narrowed with respect to the upper portion to provide even less risk from interfering with the inner bore of the ball valve during the movement of the valve and even more importantly, to furthermore provide a larger passage for the waste fluids in the drain trap device to reduce the risk of obstruction.
  • the ball valve mechanism is operated by means of the rotating handle 3, which is connected to the valve ball 9 by means of an axle 14, reaching through the housing of the bottom part 2 of the drain trap device, in a completely fluid tight way.
  • the shape and size of the handle 3 is not specifically relevant in the context of the actual invention, and may therefore involve any convenient, aesthetic and/or unobtrusive design, provided that the users can easily rotate the handle.
  • Figure 6 shows an alternative embodiment of the drain trap device according to the invention, comprising a tubular section (plastic pipe) 7 only extending to above the ball valve, without a narrowed bottom portion.
