Definitions

  • the invention relates to a hydraulic connection means for a vessel expansion on a hydraulic network.
  • the flow of water derived from the main line to the vessel expansion is low compared to the total flow.
  • the invention proposes to remedy these drawbacks in particular.
  • the invention also relates to the expansion vessel provided with said way.
  • the fluid distribution network such of water includes an expansion tank.
  • this expansion vessel has two chambers, one of which is delimited by an elastic bladder filled with a gas.
  • a hydraulic connection means 1 connects the vessel 2 expansion to a pipe 3 conveying the fluid of the network.
  • the arrival pipe is a length pipe variable and this pipe has a means 9 for modifying the length thereof response to the movement of the fluid in said inlet pipe.
  • This supply line comprises at least two sections 10.11 telescopic, one (10) fixed and the other (11) mobile, the mobile section 11 being housed in the fixed section and having a bearing surface 12 which extends in a plane intersecting in the direction F of the water flow in this pipe for, like a piston; be subjected to the pressure of the fluid circulating in said pipe of arrival.
  • the displacement of the mobile section optimizes the mixing of the water in the vase expansion with water from the pipeline.
  • the bladder membrane easily repels the mobile section and, in addition, the shape of the end of this movable section ensures a circulation even if there is contact between the bladder and the movable section.
  • connection means comprises, on the one hand, a isolation valve 13 intended to temporarily close the inlet pipes and to isolate them from the main pipe and, on the other hand, a tap 14 purge to empty the contents of the vase or to check the vase or any bladder leaks.
  • the drain valve is mounted on the discharge pipe and, preferably, this purge valve is integrated in the isolation valve of the minus the exhaust pipe.
  • the valve for isolating the inlet pipes and evacuation system comprises a single operating member 15 which moves the two shutters 16,17 each controlling a pipe.
  • Each of these inlet and outlet rooms has a seat on which applies the corresponding shutter.
  • the partition wall is formed by an annular piece attached to the operating member or obtained by machining or molding this rod maneuver.
  • At least one O-ring seal is provided.
  • the drain valve When the drain valve is integrated on the isolation valve, it is housed in an axial bore of the operating member.
