Abstract
Description
- The present invention, as stated in the title piece of this descriptive specification relates to an aeration valve adapted to a sewage network. In the anti-siphon traps presently in existence, when a drawdown or vacuum is created at their outlet, either through toilets being flushed or for some other reason, since there is no way to offset this vacuum, the liquid intended for the hydraulic seal of the trap is sucked towards the outlet, resulting in the partial or complete loss of its effectiveness, through the reduction or disappearance of said hydraulic seal with the ensuing emission of disagreeable odours to the exterior.
- Hence, the object of the invention in question is directed at overcoming the problem described in the foregoing paragraph in a simple manner, so that when the drawdown vanishes, from the sewage pipes, the aeration valve returns to its closed, idle position, whereby the bad and unpleasant odours that build up in the sewage pipes are also avoided.
- At present, in existing anti-siphon traps, when a drawdown or vacuum is formed at their outlet, either through the flushing of toilets or for some other reason, since there is no way to relieve this vacuum, the liquid intended for the hydraulic seal of the trap is sucked towards the outlet, resulting in the partial or complete loss of its effectiveness, through the reduction or disappearance of said hydraulic seal and the ensuing emission of disagreeable odours to the exterior.
- At present, to overcome these effects, sewage systems are fitted with parallel ventilating lines or aeration valves. In the case of newly constructed buildings, installing parallel ventilating lines is straightforward but expensive. Aeration valves are also costly.
- In buildings which are already standing, installing ventilating lines is practically impossible, while fitting aeration valves usually involves major structural work.
- To remedy the problems and drawbacks mentioned in the foregoing section, the invention proposes an aeration valve adapted to a sewage network with the intention of obviating a situation of total or partial vacuum that sometimes arises in sewage pipes, including the anti-siphon traps fitted in said sewage pipes.
- Thus, to counteract the suction effect produced by the vacuum, the valve of the invention has been developed which shall be installed in a short vertical tubular duct which communicates essentially with an outlet pipe from an anti-siphon trap. Notwithstanding, the short vertical duct in which the valve of the invention is installed, could also be mounted in other points of the sewage piping network.
- The vertical duct mentioned communicates with an upper chamber, inside which there is a tubular segment which communicates with the exterior through its underside, while over the mouth of this tubular segment is fitted a flexible seal which normally keeps said mouth shut. This flexible seal is held in position by means of a supporting or fastening element.
- The upper chamber is closed on its top side by means of a threaded cap and an intermediate airtight gasket.
- With the arrangement described, when a vacuum or drawdown is formed inside the sewage piping, it happens that the vacuum itself serves, by suction, to position the flexible seal upwards, thereby freeing the mouth of the tubular segment on which said flexible seal is normally seated, so avoiding the liquid being emptied from the anti-siphon trap thanks to the admission of air which is produced through the tubular segment.
- Once the drawdown or vacuum has been removed from the sewage piping, the flexible seal immediately returns to its normal, closed position, seated once again on the mouth of the short tubular segment which communicates via the underside with the exterior thereby blocking the admission of air, so avoiding unpleasant odours by preventing these from penetrating to the exterior.
- It is to be pointed out that anti-siphon traps with aeration valve incorporated can replace any other trap which does not have said valve with no need for complicated jobs or works.
- Herebelow, to assist in a better understanding of this descriptive specification and forming an integral part thereof, a number of drawings are attached in which in an illustrative and not restrictive manner, the object of the invention is shown diagramatically.
- Figure 1.- Shows a perspective of an anti-siphon trap which includes the aeration valve, object of the present invention.
- Figure 2.- Shows a partly sectioned elevation of that illustrated in the previous figure.
- Figure 3.- Shows a perspective of an accessory which is connected to the piping or anti-siphon trap which forms part of the sewage system. Said accessory incorporates the valve of the invention.
- With reference to the numbering scheme adopted for the figures, the aeration valve adapted to a sewage network is advantageously installed in a short
vertical duct 1 which communicates essentially with anoutlet pipe 2 of ananti-siphon trap 3. The short vertical duct communicates in turn with anupper chamber 4, inside which there is atubular segment 5 which communicates with the exterior through its underside. Over themouth 6 of thetubular segment 5 is seated a thin dome-shaped piece 7 which forms part of aflexible seal 8 which also includes a cylindrical,tubular body 9, theflexible seal 8 assembly, in its idle position, closing the mouth oftubular segment 5. - The
flexible seal 8 is correctly positioned by means of aretaining element 10 which essentially comprises aspindle 11, on the upper part of which is fitted theflexible seal 8 through the centrally located hole in the cylindricaltubular body 9, whilst the lower part is attached to and fits inside a narrowtubular prolongation 12 arranged coaxially withtubular segment 5. Moreover, the upper end of theretaining element 10 has aflat disc 13, the edge of which is extended downwards forming anannular wall 14, the free edge of which is situated close to the upper face of the thin dome-shaped piece 7 of theflexible seal 8. - The
upper chamber 4 is closed at the top by means of a threadedcap 15, with the insertion of anintermediate airtight seal 16. - Thanks to threaded
cap 15, it is possible to gain access to the inside ofupper chamber 4, not only for fitting the valve assembly of the invention, but also for access to the valve interior when necessary. - With the arrangement described above, when a vacuum or drawdown occurs in the sewage piping, the very vacuum effect mentioned serves to provide the suction which draws the thin dome-
shaped piece 7 pertaining toflexible seal 8 upwards thereby freeingmouth 6 oftubular segment 5 on which saidflexible seal 8 is normally seated, avoiding in this manner the emptying of the liquid from thecorresponding trap 3. - Once the drawdown or vacuum in the sewage piping has been removed, the
flexible seal 8 immediately returns to its normal closed position, seated once more on the mouth of shorttubular segment 5 which communicates on the underside with the exterior, so preventing the admission of air. - The valve of the invention can also be installed in anti-siphon traps by using a standard accessory 17 (male-female or female-female), as is illustrated in figure 3.
- This facility permits direct installing of the valve of the invention on normal anti-siphon traps as is shown in figures 1 and 2, and also on traps already installed, via the accessories (17) mentioned in the preceding paragraph, which incorporate the respective valve.
- Finally, it is also possible to fit the valve at other points of the sewage piping.
