Definitions

  • the invention refers to the field of systems for supplying a fluid from a primary circuit to a secondary circuit, with physical separation of the fluid in the primary circuit from the fluid in the secondary circuit. More particularly, but not exclusively, the invention relates to a water supply system in buildings, for example for drinking water, starting from a public supply network, containing water under pressure, to a user represented, for example, by the circuit of a single building. Another type of use of the invention is, for example, for supplying water to a single sink or sanitary fitting and for forced drainage of water therefrom.
  • a system for conveying fluid through pipes must generally be suitably pressurized and can at times, for accidental reasons, be subject to a vacuum, drawing the fluid back in the opposite direction. This occurrence cannot always be avoided with check valves.
  • the aim of this invention is to overcome the problem of repressurizing user water without being obliged to use separate power consuming devices, such as electric pumps and the like.
  • the system of this invention comprises a first fluid circuit connected to a source of fluid under pressure and supplying a second fluid circuit by pouring or sprinkling; the second circuit supplies the user.
  • a first fluid actuator is installed on the first fluid circuit;
  • a second fluid actuator is installed on the second fluid circuit;
  • the first and second fluid actuators have their mobile members physically constrained one to the other;
  • valves are provided on the circuit so as to supply alternately one and the other chamber of the first actuator, which thus acts as a fluid motor to move the second actuator, which pressurizes the fluid in the user's circuit.
  • the new system or plant makes it possible to use fluid pressure in the first circuit to pressurize fluid in the second circuit without requiring power to be supplied from outside the system, thus without additional operating costs or with minimal additional costs, also overcoming the problem of pump noise, in that the repressurization system is particularly noiseless.
  • FIG. 1 shows a system according to the invention, placed between a water supply consisting of the municipal network, indicated by R, and a user, indicated by U.
  • the system indicated as a whole by reference 10, comprises a primary circuit 12 and a secondary circuit 14.
  • the primary circuit 12 is connected to the municipal network R and comprises, downstream thereof, two pipelines 15 and 16, parallel to each other, connected to opposite chambers A and A' of a fluid actuator 1, consisting, in the particular example, of a cylinder-piston assembly.
  • a valve 1A is on the pipe 15 and a valve 2A on the pipe 16, both being controlled valves.
  • the circuit 12 Downstream from the actuator device 1, the circuit 12 comprises two pipelines 17 and 18, respectively, parallel one to the other, the pipeline 17 being equipped with the valve 4A and the pipeline 18 with the valve 3A, both controlled valves.
  • the pipelines 17 and 18 then converge into the pipe 19 which ends in a spray or pouring head 20.
  • the secondary circuit 14 comprises a free-surface reservoir C, supplied by the sprayer 20 (but in which the fluid or liquid l is physically separated from the sprayer 20), a pipeline 21 downstream from the reservoir C, which supplies two parallel pipelines 23, 24 with valves 3B and 4B which open into opposite chambers B and B' of a fluid actuator 2.
  • the actuator is a cylinder-piston.
  • two pipelines 25 and 26 leave chambers B and B', respectively, and are connected, parallel one to the other, to a pipeline towards the user U.
  • a valve 2B is present on the pipeline 25, a valve 1B on the pipeline 26.
  • the valves 1B, 2B, 3B and 4B can be check valves or controlled valves.
  • the pistons of the actuator devices 1, 2 are rigidly connected one to the other in this particular case by a single stem S.
  • valve 1A feeding the chamber A opens and so at the same time does the valve 3A connected to the chamber A', maintaining the valves 2A and 4A closed, as illustrated in Figure 3.
  • valves 3B and 1B open.
  • the network pressure acts in the chamber A of the actuator 1 and, overcoming the pressure in the chamber A', delivers the liquid contained in A' through the sprayer 20, whilst when the piston 102 moves inside the cylinder 101, there is a simultaneous movement of the piston 202 inside the cylinder 201 which allows the chamber B to fill and the chamber B' to empty. If the size of the actuator 1, acting as a fluid motor, and the size of actuator 2, acting as a pump, are equal, the pressure in chamber A will be substantially equal to the pressure in chamber B', provided there is no friction.
  • Figure 6 shows a scheme of a system 10x in which, instead of cylinder-piston actuator devices, per se known diaphragm actuator devices are used, indicated by 1x and 2x. Since operation of the system remains essentially identical, no detailed description of the system in Figure 6 is provided, and the same reference numbers as for the preceding figures have been maintained.
  • Figure 7 shows various ways of using the system or plant of the invention.
  • a system 10 can be applied at the inlet to a building where the overall circuit of the building is connected to the municipal water supply network R.
  • the pipelines of the municipal network are drawn with a thick unbroken line.
  • the system 10 makes it possible to pressurize the clean water supply circuit of the residential building (drawn with a broken line) though maintaining the physical separation in C with respect to the municipal network and exploiting the network pressure to obtain the supply circuit pressure.
  • FIG. 7 another three systems 10 are illustrated, used in this case on the water circuit of the residential building, to provide pressure in the drains of service apparatus situated on a lower level that the level of the sewage network.
  • the primary circuit in this case consists of the residential water supply circuit (broken line) and the secondary circuit consists of the sewage circuit (chain).
  • the system 10' makes it possible to exploit the clean water pressure present in the domestic water circuit to wash a toilet bowl with falling water and forcibly evacuate the drain. The same applies to the system 10'' situated upstream and downstream from a washroom and to the system 10''' situated upstream and downstream of a sink.
