Definitions

  • the invention relates to a device for preventing aspiration by siphon effect (siphoning) in hydraulic taps provided with a cartridge comprising flow control members in the form of flat plates of hard material.
  • the object of the present invention is to provide a hydraulic valve comprising a cartridge comprising flow control members in the form of flat plates of hard material, which valve must itself include a valve. independent ventilation of the cartridge.
  • An accessory object of the invention is to provide a tap having the above-mentioned characteristic which, moreover, must be capable of accepting a normal cartridge, as it is usually inserted in taps devoid of a ventilation valve. .
  • Yet another object of the invention is to achieve the objects above indicated by a minimum increase in the cost price.
  • the one-way valve with elastic lip remains closed.
  • the pressure in the interior region of the tap becomes higher than atmospheric pressure, and the one-way valve with elastic lip is kept tightly closed by this pressure, thus avoiding any loss of water through said entry passages.
  • the non-return valve with elastic lip opens automatically, thus allowing the entry of air through said inlet passages and to the interior region of the valve, which is in communication with the flow outlet. In correspondence of this exit, therefore, it can never establish an appreciable depression, and this surely prevents any siphoning phenomenon.
  • the stated principle of the invention can be implemented constructively in different modes, either with regard to the arrangement of the inlet passages, or with regard to the arrangement of the one-way valve with elastic lip and of the organ which acts as a valve seat.
  • a first possibility is to produce these passages by means of openings made for this purpose in the cover itself.
  • a second possibility is to produce these passages in the form of channels formed partly in the opening of the cover intended for its coupling with the contained cartridge, and partly in the external region of the cartridge itself.
  • a third possibility is to make these passages by means of channels formed only in the opening of the cover intended for its coupling with the cartridge.
  • a fourth possibility is to make these passages only in the external region of the cartridge.
  • the one-way valve with elastic lip it can be installed between the valve cover and the contained cartridge, or between the cover and the valve body.
  • the elastic body constituting the valve with elastic lip can also act as a seal which, in any case, should be interposed between the cover and the valve body.
  • this member may be constituted by an internal surface of the cover, or by an internal surface of the body of the tap, or even by a part of the cartridge having the shape of a bead.
  • the tap schematically includes a hollow body 1 and a cover 6, screwed onto the body 1 by means of a thread 3.
  • a seal 2 is interposed between the body 1 and the cover 6.
  • a cartridge is introduced, of which there is a housing 11 crossed by flow openings 12, a bead portion 13 and an upper portion 14 from which an operating member 15 projects.
  • the parts 14 and 15 of the cartridge pass through a central opening in the cover 6.
  • the inlet passages consist of openings 7 formed through the cover 6.
  • an annular body 9 of elastic material from which protrudes outward an elastic lip 10 which extends beyond the openings 7 and bears against the internal surface of the cover 6, which acts as a valve seat.
  • the elastic lip 10 therefore divides the internal space of the valve body 1 into an interior region 4, which is in communication with the flow openings 12 of the cartridge (as well as with any flow passage not shown, constituting the outlet of the tap), and an outer region 5, which is in communication with the ambient air through the openings 7 of the cover 6.
  • the elastic lip 10 remains pressed against the surface internal of the cover 6.
  • the pressure in the interior region 4 becomes higher than atmospheric pressure, due to the resistances opposed to the flow downstream of the tap, and this pressure pushes strongly the elastic lip 10 against the cover 6, thus preventing any outflow of water through the passages 7.
  • the pressure in the interior region 4 becomes (in a minimum measure) more reduced than atmospheric pressure.
  • the latter by acting in the outer region 5 against the elastic lip 10, raises the latter from the inner surface of the cover 6. Then the ambient air can freely enter the inner region 4 of the valve body, compensating for the depression which tended to establish itself, so that it cannot assume appreciable values. Any siphoning phenomenon is thus prevented.
  • the elastic body 9 with the lip 10 therefore acts as a one-way valve preventing siphoning.
  • the elastic body 9 of the one-way valve with elastic lip acts as a spacer to hold the cartridge 11-15 in position in the body 1 of the valve, but it does not have the function of establishing the sealing between the valve body and the cover.
  • Figure 1 also shows, by way of modification, as in an alternative form, the elastic lip 10 ′ of the one-way valve could be shaped.
  • the lip 10 'bears in a sealed manner, not against the internal surface of the cover 6, but against the internal surface of the body 1 of the valve, which in this case acts as a valve seat.
  • the different parts of the tap, of the cartridge and of the one-way valve, which correspond to parts according to FIG. 1, are indicated by the same reference numbers increased by 20 units; they will not be described later.
  • the cartridge bears directly against the cover 26, and the annular body 29 of the unidirectional valve is clamped between the body 21 and the cover 26. In this way it acts as a seal between said parts, and consequently there is no
  • the packing 2 according to FIG. 1 has not been provided for any more. Otherwise, the operation which is obtained is identical at all to that which has been described with respect to the embodiment according to FIG. 1.
  • the different parts of the tap, of the cartridge and of the one-way valve, which correspond to parts according to FIG. 1, are indicated by the same reference numbers increased by 40 units; they will not be described later.
  • the annular body 49 of the one-way valve is clamped between the body 41 and the cover 46 and it acts as a seal between these parts.
  • the lip 50 of the one-way valve is directed towards the bead portion 53 of the cartridge, which, in this case, acts as a valve seat.
  • the inlet passages could also be constituted by openings made through the cover 46, as in the previous cases, but here they can also be constituted by channels 56 formed in the external part 54 of the cartridge and by corresponding channels formed in an internal flange 48 of the cover 46, serving as a shoulder for the cartridge. Apart from that, the behavior which one obtains is still identical to that which has been described in connection with the embodiment according to FIG. 1.
  • channels constituting inlet passages 76 ′ could also be provided only in the external region of the cartridge. In this case it would not be necessary to provide channels in the flange 68 of the cover 66, forming a shoulder.
  • FIG. 5 corresponds to the diagram according to FIG. 1, but we see here that the internal surface of the cover 86, acting as a valve seat, can also be the cylindrical internal surface of the cover, instead of its surface internal plate as in FIG. 1.
  • the lever operating member 95 is coupled to an articulation ball 96 fitted between the upper part 94 of the cartridge, acting as an upper semi-cushion. , and a lower semi-cushion 99 forming part of the housing 91.
  • a seal 98 is inserted between these parts.
  • the internal end 97 of the operating member engages a slide 100, guided in the cartridge by a guide ring 101, and coupled with a movable flow control plate 102 made of hard material.
  • the latter can slide in sealing contact with a fixed flow control plate 103 of hard material, mounted in a bottom 104 of the housing 91 of the cartridge.
  • the bottom 104 of the cartridge is coupled by means of projections 105 with seats at the bottom of the body 81 of the valve, to which the supply lines 106 arrive.
  • the number 107 designates a possible arrangement of the flow conduit, which on the other hand can be also provided in any other position, according to the installation requirements.
  • the operation of a tap and a cartridge like those which have been described is well known and does not require to be described in detail.
  • the interior region 84 of the valve body is in communication with the flow conduit 107 and it receives the water, which has been mixed in the cartridge, through the openings 93 of the housing 91 of the cartridge.
  • This interior region extends, through the gap between the housing 91 of the cartridge and the body 81 of the valve, to the one-way valve 89-90 which, under normal conditions, separates the interior region 84 from the exterior region 85
  • the latter is in communication, through the openings 87 of the cover 86, with the ambient air.
  • the lip 90 of the one-way valve rises from the internal cylindrical wall of the cover 84.
