Abstract

A boiler is provided with a heat exchanger having a front face provided with a sanitary inlet port, a sanitary outlet port, a heating inlet port and a heating outlet port, and a hydraulic group for connecting the secondary heat exchanger to a heating circuit and to a sanitary circuit; the hydraulic group is provided with a one-level pressure switch for the heating circuit, a three way valve provided with and electric actuation group, a sanitary flow switch provided with filter, and a by pass valve; the hydraulic group features a first connection assembly and second connection assembly; the hydraulic group having a flow pipe for connecting the first and the second connection assemblies and a by pass valve arranged inside the flow pipe, which is parallel to the front face of the secondary heat exchanger.

Description

    General
  • The present invention relates to a boiler provided with a functional group featuring an aggressive price/performance ratio, a reference architecture with system standardization, reduction of the number of components to prevent codes proliferation, simplification of assembly and testing procedures with consequent reduction of production time, modular design for use on boilers with different architectures.
  • A product featuring pexformance and reliability improvements enabling to minimize field failures and to switch from an hydraulic to a motorized system using components made of composite material.
    • Modified elements
  • The elements presenting a greater innovation as compared to the current model are in bold type (reference European patent no. 0652408, enclosed)
    • Inclusion of quick fastening systems with o-ring seals and fastening pin or clamping screw.
    • Inclusion of hoses with fastening pin at one of the two ends
    • Previous by-pass valve (head + spring + sealing ring nut) replaced by a by-pass valve, diameter 20, providing easier and more reliable disassembly
    • Application of a limestone-proof system consisting of a check valve (reference our European patent request no. 97830588.6 filed on November 11, 1997)
    • the group has been conceived as modular in order to obtain with the same components the following versions :
      • heating only
      • heating only with connection to remote boiler
      • heating + sanitary water
    • the hydraulic group inside the boiler has been standardized leaving to the template, provided separately with different configurations, the function to match the various types of plant loading system available in the different countries.
    • Inclusion of one-level safety pressure switch for heating purposes to replace the mechanical differential flow switch consisting of a diaphragm, a cap, a spring, a spindle and a micro for the electric signal. The differential flow switch authorizes gas ignition when the following two conditions under its control occur:
      • The water pressure is sufficient
      • The pump is running
      The one-level pressure switch, connected to the electronic card, checks the water pressure while circulation is kept under control by an intelligent probe. The one-level pressure switch is a completely new component and its use allows to replace the differential flow switch increasing reliability and making the control of water pressure easier.
    • Inclusion of a 3-way electric actuator allowing to switch from a 3-way hydraulic system with intermediate control lever (at rest when in heating position) to a direct electric actuator of new design with built-in over stroke (at rest when in sanitary water position) to reduce the user's waiting time for the hot sanitary water.
    • Inclusion of a sanitary flow switch complete with filter, allowing to switch from a diaphragm (venturi) priority system for sanitary water to a sanitary priority system with a float + magnet flow switch controlled by a reed switch to reduce the user's waiting time for hot sanitary water.
    Enclosed please find :
    • 3 color assembly views of the new hydraulic group
    • diagram of the new hydraulic circuit
    • exploded view of the new hydraulic group evidencing the sanitary flow switch, the 3-ways actuator and the new pressure switch
    • drawing of the heating by-pass
    • specifications and drawing of the electric actuator
    • specifications and drawing of the heating pressure switch
    • specifications and drawing of the sanitary pressure switch
  • It is an object of the present invention to achieve the above tasks in a straightforward and economic way. According to the present invention there is provided a boiler comprising a heating circuit, a sanitary circuit a main heat exchanger connected to the heating circuit, a secondary heat exchanger having a front face provided with a sanitary inlet port, a sanitary outlet port, a heating inlet port and a heating outlet port, and a hydraulic group for connecting the secondary heat exchanger to the heating circuit and to the sanitary circuit; said hydraulic group comprising a one-level pressure switch for the heating circuit a three way valve provided with and electric actuation group, a sanitary flow switch provided with filter, a by pass valve; the boiler further comprising a first connection assembly provided with quick fastening means comprising pin or clamping screw for connecting said first connection assembly to said secondary heat exchanger and second connection assembly comprising quick fastening means for connecting said second connection assembly to the secondary heat exchanger, the first connection assembly connecting the heating circuit to the heating outlet port and the sanitary circuit to the sanitary inlet port and the second connection assembly connecting the heating circuit to the heating inlet port and the sanitary circuit to the sanitary outlet port; characterised in that said hydraulic group comprises a flow pipe for connecting the first and the second connection assemblies and a by pass valve arranged inside said flow pipe; said flow pipe being parallel to said front face of the secondary heat exchanger.
