Definitions

  • the invention relates to mixed central heating boilers, that is to say to devices intended for heating water in two circuits, one intended for central heating by circulation of hot water in radiators or the like. and the other to hot water draws called “sanitary" for the toilet, the kitchen ..., the calories necessary for the heating of this water being preferably generated by combustion of a combustible gas.
  • the invention overcomes these drawbacks and proposes to this end to constitute the connecting portions of boilers of the kind in question by special "bars", the construction of which is particularly simple and economical, bars making it possible to test the central heating circuit under pressure in the absence of the boiler proper, that is to say of the active portion, of this boiler, including the burner and the heater.
  • connection portions of the type in question according to the invention are essentially characterized in that they comprise four modular elements or "modules" molded assembled side by side by mutual juxtaposition and common crossing of tie rods preferably comprising ends threaded cooperating with clamping nuts, in that the first module comprises an inlet which can be connected to the boiler start-heating piping, an outlet which can be connected to the heating-starting pipe to the radiators, a conduit connecting this inlet to this outlet, a manual isolation valve mounted on this conduit, a safety valve connecting said conduit to an evacuation pipe, and a short-circuit section suitable for connecting the above conduit with the second module, in that this second module includes an input that can be connected to the boiler domestic hot water flow pipe, an output that can be connected the domestic hot water flow pipe to at least one draw-off tap, a conduit connecting this inlet to this outlet, a short-circuit section crossing said second module from the first to the third module, and a pressure gauge connected to this last section, in that the third module includes an outlet which can be connected to
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
  • FIG. 1, of these drawings very schematically shows a mixed central heating boiler, the connection portion of which is connected to the external piping consists of a bar established in accordance with the invention.
  • FIG. 2 shows the same bar schematically, but in more detail.
  • Figure 3 shows in side view an embodiment of said bar.
  • Figure 4 shows in perspective view one of the constituent modules of this bar.
  • the combined boiler considered comprises, inside a casing 1, a burner 2 supplied with pressurized combustible gas from a network 3 via a gas pipe 4 associated with safety means (not shown) and with a tap 5.
  • the closed heating circuit comprises, inside the casing 1, an exchanger 6 in which the circulating water collects the calories generated by the flames 7 of the burner 2 and, outside said casing, a pipe 8 passing successively the heating radiators 9 and a circulation pump 10.
  • the drawing-off circuit successively comprises, from an external source of pressurized water 11 generally constituted by a city network, an external intake pipe 12, an exchanger 13 inside the casing 1 also making it possible to collect the calories produced by the flames 7 and an outlet pipe 14 ending in at least one tap 15.
  • connection portion R which is interposed between the external pipes 8, 12 and 14 and the internal pipes comprising the exchangers 6 and 13.
  • connection portion R is here constituted by a set of molded hard plastic modules which are juxtaposed against each other and joined together by tie rods 16 advantageously constituted by rods whose threaded ends cooperate with tightening nuts 17.
  • the different modules are arranged in such a way that their simple juxtaposition connects the different short-circuit sections 26, 31, 38 and 46 comprised by the four modules end-to-end in a sealed manner.
  • end pieces of sections to be mutually connected are arranged so as to fit one into the other with the interposition of an O-ring 47 housed in an appropriate groove hollowed out in the external cylindrical face of the male end piece. of each pair end caps.
  • connection strip R it suffices then to place three plugs (not shown) respectively on the three mouths 18.33 and 40 of the connection strip R, as shown diagrammatically by crosses in FIG. 1, then to open the various taps 23.37 , 39 and 45.
  • the third module C is associated with a safety member 48 (FIG. 2) arranged so as to, on the one hand, make it possible to supply the heating circuit, and more precisely the short-circuit pipe. 26,31, 38,46 by the pressurized water from the network and, on the other hand, making it impossible to return to the conduit 36 -and therefore to the supply network 11- of a portion of the water circulating in the heating circuit and more precisely in the short-circuit pipe above.
  • a safety member 48 FIG. 2
  • This member 48 is connected to the discharge pipe 25 of the first module by means of discharge sections 49, 50, 51 understood respectively by the first three modules A, B and C and arranged, like the short sections. above circuit, so as to be automatically connected end to end in a sealed and automatic manner by the simple mutual juxtaposition of the three modules considered.
  • the barrier member 39 is here a valve with two valves 52 and 53 mounted in series on the same rod 54 and adapted to communicate respectively the conduit 36 with a compartment a and the section 38 with a compartment b both crossed by said rod and connected to each other through safety member 48.
  • a third compartment c disposed between the two compartments a and b and also crossed by the rod 54 is brought into the open air through a conduit 55.
  • This conduit is used to evacuate to the outside the few drops of water which could leak at the level of the crossings, by the rod 54, of the dividing partitions between, on the one hand, the compartments a and c and, on the other hand, the two compartments b and c , crossed, which are sealed with O-rings or the like 56.
  • valves 52 and 53 are closed simultaneously by actuation of a single rod 54.
  • the security member 48 sometimes called a "backflow preventer" can be constituted in any manner known per se and is not the subject of the present invention.
  • This member 48 can be incorporated into module C or attached to it, in particular using screws.
  • the fourth module D advantageously comprises a relief valve 57 (FIG. 2) mounted on the section 46, this valve being biased towards its closed position by a spring 58 calibrated so that it opens only if it exists in the heating circuit a pressure drop exceeding a given threshold, for example due to the closing of too many thermostatic valves.
  • the isolation valve 45 fitted to the fourth module D is advantageously fitted with a filter 59 which is easily removable when the valve in question is closed, a filter making it possible to retain impurities coming from the heating circuit and to prevent their sending into the body. boiler heating.
  • the fifth module E comprising an inlet 60 connectable to the piping 4 for external supply of pressurized gas, an outlet 61 connectable to the piping 4 for supplying gas to the burner 2 of the boiler, a conduit 62 connecting this inlet to this outlet and the isolation valve 5 above mounted on said conduit 62.
  • the molded material making up the modules can be different according to the modules, and adapted to the operating temperatures, the modules assigned to a circulation of cold or lukewarm water (C and D) or to the electrical connections (F) can be made of a less efficient material than those assigned to a circulation of hot water (A and B) or that of gas (E).
  • This material could be a metal such as an aluminum alloy, but is preferably an injected plastic, which has many advantages (economy, lightness, resistance to corrosion ).
  • This plastic material is for example a polyether sulfone (commonly called PPS), a polyether imide (PEI) or a polyphenylene sulfone (PES) for modules A, B, C, D and F and even for a peripheral portion of module E, the internal portion of said module E, directly in contact with the gas, then being formed by a metal core.
  • PPS polyether sulfone
  • PEI polyether imide
  • PES polyphenylene sulfone
  • Said material can also be an epoxy resin to constitute the entire module E.
  • Each molded module advantageously comprises a prismatic or cylindrical peripheral belt 63 (FIG. 4) whose contour is substantially rectangular with rounded corners, four rectilinear channels 64 respectively disposed at the four corners of this belt and intended to receive the tie rods 16 and a plurality of straight or bent tubular sections T braced by generally flat sails V extending perpendicular to the generatrices of the prism or cylinder defining the belt.
  • module B which has been shown isolated in perspective in FIG. 4 is module B.
  • said strip R is previously mounted on a wall, at a relatively great distance from it, for example of the order of 20 cm, using two metal cheeks 66 crossed by the ends of the tie rods 16 .
  • connections with the external pipes 21, 14, 12, 43 and 4 can then be easily carried out on the waiting inputs and outputs 20, 29, 35, 42 and 60, behind the bar R, between it and the wall, in particular using screw connections.
  • connection of the boiler to the bar R thus mounted and connected is then carried out by placing this boiler above this bar, the ends of the pipes 19, 28, 34, 41 and 4 internal to said boiler opening side by side towards the bottom below it, then lowering the boiler so as to juxtapose suitable connecting members terminating said end pieces against those which are on standby in 18,27,33,40 and 61 and finally by assembling the juxtaposed fittings two by two.
