Definitions

  • the invention relates to a device for protection against the entry of water into a apparatus comprising a vent, in particular a gas regulator, placed in a tank closed by a cover and intended to be buried.
  • the bottom of these tanks has at least one drain hole so that water that has seeped into the tank can flow into the drained area surrounding the lower part of the tank.
  • water may enter the unit through its vent breathing and thus affects its functioning.
  • Patent application FR-2 727 773 describes gas pressure regulators housed in buried boxes and fitted with an anti-invasion vent system to prevent water from entering the regulator.
  • the wind thus has an extension which has an open volume downwards intended to prevent the rise of water in the vent.
  • the object of the invention is to provide a device for protection against entry. of water from an appliance fitted with a vent, which can be used for all appliances whatever their size, and which does not oblige to equip these devices with a integrated anti-invasion system.
  • the device intended to be buried in the ground, comprises a tank containing the device and its vent, the upper part of said tank being closed by a cover allowing access to the tank, and the lower part of said tank being in contact with the ground.
  • the tank has a duct having an opening located inside the tank, at a distance from the bottom of said tank.
  • the opening of the duct is closed by water, so as to produce in said tank a closed volume of air of waterproof way.
  • the conduit is a tube passing through the tank.
  • the conduit is a channel integrated into the structure of the tank.
  • the conduit is a bell placed at inside the tank.
  • a first variant of these different embodiments consists in closing the tank by a sealed cover mounted in a sealed manner on said tank, the venting of the tank being ensured by the conduit, which communicates with the outside of the tank.
  • This duct may include, in its upper part, an extension which opens to the outside of the tank.
  • the conduit does not communicate with the outside of the tank, but communicates with the vent of the device.
  • the tank is vented either by the lid, which is not waterproof or is mounted on said tank in a leaktight manner, either by a vent tube connecting the inside and outside of the tank but not communicating with the conduit.
  • the device described by the invention provides for providing the conduit with a mesh or a breathing membrane placed at its opening towards the bottom.
  • the device according to the invention comprises a tank 1 watertight containing a device 2 such as a gas regulator, the part upper part of this tank 1 being closed by a cover 3 allowing access said device 2, in particular for maintenance.
  • a device 2 such as a gas regulator
  • This tank 1 is placed at the bottom of a hole 4 made in the ground, closed by a buffer 5 comprising at least one orifice 6 which allows inside the hole 4 to communicate with the atmosphere.
  • the tank 1 comprises means of communication with the hole 4, so that the interior volume of the tank 1 is at atmospheric pressure.

  • the tank 1 has on its bottom at least one drain hole 14 allowing the evacuation of the water which could be present in the tank 1.
  • the device 2 placed in the tank 1 is provided with a breathing vent 15 opening out inside the tank 1. In this way, the device 2 is connected to a volume at atmospheric pressure which is a necessary condition of good operation for pressure regulators.
  • the tank 1 comprises a tube 16, the connection between the tube 16 and the tank 1 being waterproofed.
  • This tube 16 has inside the tank 1 a opening 18, located inside the tank 1 at a certain distance D from the bottom tank 1.
  • the tube 16 is passed through the flange 17 of the tank 1 and opens into the hole 4, outside the tank 1.
  • the upper end 19 of the tube 16 is located above the level of the cover 3 in order to guarantee the the atmosphere of the interior volume of the tank 1 even in the event of sand being deposited, gravel or others at the level of the cover 3.

  • the water will rise to a level located at a distance h from the opening 18 of the tube 16.
  • This device which can be installed on a standard tank, is suitable for all regulators, including large regulators, for example of type B and C for a flow rate of 30 to 80 m 3 / h. These regulators no longer need to be fitted with an anti-invasion vent system. In fact, it suffices that the breathing vent 15 of the regulator is situated above the level D + h. By placing the opening 18 of the tube 16 as close as possible to the bottom of the tank 1, for example at a distance of 10 mm, this condition is always fulfilled.

  • This facade vent configuration is more particularly used in case location of tank 1 in an area at high risk of rising water.
  • FIG. 3 represents a third variant of this first embodiment.
  • the tube 16 does not communicate with the outside of the tank 1.
  • the upper end 19 of the tube 16 can be closed by a plug 20.
  • the interior volume of the tank 1 is vented by the cover 3, which is not leaktight or that is not leaktightly mounted on tank 1.
  • vent tube 29 connecting inside and outside of the tank 1 but not communicating with the tube 16.
  • the tube 16 communicates with the breathing vent 15 of the device 2. This can be done for example by a flexible hose 21 connecting the vent 15 of the device 2 to a connector 22 present on the tube 16.
  • This device is applicable, on a standard tank, to all types of small devices not equipped with an integrated anti-invasion system, in particular to regulators working at flow rates between 6 and 30 m 3 / h.
  • a second embodiment of the invention consists in forming a channel 23 in the structure of the tank 1, as shown in FIGS. 4a, 4b and 5.
  • This channel 23 forms a zone inside the tank 1 which comprises at least three openings 18, 24, 25.
  • a first opening 18 is located in the part bottom of channel 23, at a certain distance D from the bottom of tank 1, and is generally oriented downwards.
  • a second opening 24 is located at the upper end of the channel 23 and opens into the hole 4 outside the tank 1.
  • a third opening 25 is made in the lateral part of the channel 23 inside the tank 1.

  • the tank 1 is closed by a sealed cover 3 and mounted in a sealed manner on said tank 1, so that the communication between the inside and the outside of the tank 1 is carried out only through channel 23.
  • the opening 24 of the channel 23 which communicates with the hole 4 at the outside of the tank 1 makes it possible to connect the inside of the tank 1 to the pressure atmospheric.
  • the channel 23 is equipped at this level.
  • the third opening 25 is closed, for example by a plug 27.
  • the interior of the tank 1 thus constitutes a closed volume which counteracts the rise water at a higher level. Any device 2 whose vent 15 is located above level (D + h) will therefore be protected from water intake.
  • This variant is ideal for large devices.
  • the tank 1 is, in this variant, closed by a sealed cover 3 and mounted sealingly on said tank 1.
  • the opening 24 of the channel 23 towards the outside of the tank is closed, for example by a plug 28.
