Definitions

  • valve assemblies of this type in which the control valve uses the Venturi effect to actuate or drive a rod or a piston opening or closing the three-way valve, but such devices have large load losses in the domestic water supply plant.
  • valve assemblies or double valves using a flexible diaphragm valve for operating the three-way valve, that nevertheless have some shortcomings. Namely in these devices the command rod or stem is quite long and this makes the centering difficult with a resulting difficult and irregular working of the valve assembly. Moreover the flexible diaphragm is rigidly connected to a steel pan and also accomplishes a bypass function together with a disk having thin slots that are easily subjected to be clogged. This valve assembly moreover provides for complicated seal systems to ensure that the heating water circuit and the domestic supply water circuit are kept rigorously separated.
  • the present invention aims to provide a valve assembly of the above mentioned kind that overcomes the above mentioned shortcomings and limitations of the prior art.
  • valve assembly comprising a three-way valve and an associated control valve of mechanical type that are fitted on top of each other, characterized in that such control valve comprises: a discoid-shaped body provided with an inlet duct and an outlet duct; a pan and a flexible diaphragm having a central opening, both located within control valve and axially urged upward by a first helical spring; an axially movable central stop member carrying a first stem projecting upward from said valve body to actuate the overlying three-way valve; the lower portion of said pan carrying a laterally opened central projection that houses a plunger member having an axial hole and a second helical spring urging said plunger member to obstruct said pan opening, said central projection further having a second stem protruding downward from the valve body for actuating additional electric devices.
  • the valve arrangement according to the invention comprises two portions that are mechanically coupled together, but hydraulically separated, that is an upper three-way valve 1 in which heating hot water flows, and a lower control valve 2 of the diaphragm type in which the domestic water flows.
  • the two valves are arranged on top of each other thanks to a collar 50 provided with a flared portion 51 radially projecting from the valve 2 and housed within a lower cylindrical end 54 of the valve 1 having one or more holes 52 for receiving conical fastening screws 53.
  • the upper three-way valve comprises two inlet and outlet ducts 11 and 12 respectively, for the heating water circulating through the heating plant, and a third duct 13 along which the hot water from duct 11 can be directed, the duct being connected to a heat exchanger (not shown) in which the heating water can transfer heat to the domestic water before this latter is delivered.
  • a command member is slidably fitted which comprises two stems 14 and 18 with a plunger 15 and 16 carried at each end, respectively, such plungers being provided with guide and reinforcing axially extending members, e.g. located at 120°, and designated with 45 and 48, respectively.
  • the two stems 14 and 18 are axially aligned so that an axial force applied to one of them is axially transmitted to the other.
  • the plungers 15, 16 are of plastic material, integer with the members 45, 48, and each of them is equipped with a peripheral groove for housing a rubber sealing ring (O ring), designated by 61 and 62, respectively.
  • Te lower command stem 18 is actuated by the underlying diaphragm valve 2 by means of a command stem 29 as will be explained with more details later on, whereas a helical spring 19 housed in a spring retainer within the duct 12 urges downwardly the plunger 15.
  • a pan 26 with a central opening is secured to the flexible diaphragm 24 on the side facing the lower chamber 2B.
  • a brass bush 63 is fitted to the pan opening 37 and provided with an outer groove 64 in the upper portion housing the inner lip of the flexible diaphragm 24.
  • the pan 25 has a lower central projection 30 laterally opened or formed with axially extending studs, e.g. by four of such studs located at 90°.
  • the pan and the central projection 30 are formed as a single moulded piece of plastic material. From the bottom of the seat 30 a central rod 26 projects for actuating a switch 66 (shown with phantom lines) e.g. for starting the boiler.
  • the lower surface of the pan 25 is biased by a helical spring 23 having the lower end housed in a spring retainer 28 formed at the bottom of the body portion 2B.
  • the force of the spring 23 is properly selected so that in the rest conditions the spring urges upward the pan 25 and the overlying diaphragm 24 until they abut a central stop member 31 provided with openings 32 for the water passage.
  • the upper portion of the central stop member 31 carries the actuating stem 29 projecting from the collar 50 and capable to act on the stem 18 of the three-way valve.
  • the plunger member 33 opens against the force of the spring 35 when the pressure increases and beside working as a flow limiter (by changing the hole size) it also accomplishes the bypass function of the control valve.
  • the assembly according to the invention which employs two guided short command stems does not have centering problems and the actuation results in being quite smooth. Moreover, when using an assemply according to the invention, it is possible to repair a malfunction affecting the domestic water supply without the need of emptying the heating plant and viceversa.
