Definitions

  • the present invention relates to a deflector element for fluid deviation couplings for radiator element intercepting valves.
  • the invention relates to a deflector element, otherwise indicated as a deflector organ or deflector, for example as described with one of the possible embodiments in the patent application IT1290557 .
  • deflector elements of the type indicated above are utilized in so-called “single-pipe” valves, which are used for connecting several heating bodies, such as radiators in series or parallel.
  • Valves of this type are well-known, for example from US Patent US 3,618,855 , or patent EP-A-0 441 761 , patent GB 1 433 007 and also patent DE 29 04 271 .
  • These couplings exhibit one or more connections for connecting to a radiator to allow the fluid to be delivered and returned from it.
  • the coupling is connected to the single-pipe valve, which has two connections for connecting to input and output pipes of the heating fluid, as well as a shutter to control the quantity of fluid to be delivered to the relative radiator.
  • the coupling exhibits a deflector organ that allows separately channelling the fluid from one of the pipes, for example the input one, to the delivery connection of the radiator, and channelling the fluid from the return connection of the radiator to the other pipe, for example the output one.
  • the invention suggested by the patent IT 1 290 557 foresees the use of a deflector that can be rotated to direct the fluid into the right pipe, if it is facing differently when the valve is assembled. This known deflector is then put back into the coupling to prevent it from rotating after it has been inserted into the coupling.
  • the patent application BS 2002 U 000091 shows a single-pipe valve with a reversible input and a coupling with a deflector that can be rotated into its slot provided in the body of the coupling.
  • This deflector is provided with a slot that can be accessed from outside the valve, which is suitable for receiving a chuck key to control it to go from one position to another.
  • figure 1 shows a side view of a single-pipe valve with a coupling connected to a heating element
  • figure 2 represents a side section of the single-pipe valve with the coupling in figure 1 and the shutter closed;
  • figure 3 shows a prospective sectioned view of a deflector element according to a first embodiment
  • figure 4 shows a side section of the single-pipe valve with the radiator in figure 2 and the shutter open;
  • figure 5 shows a sectioned side view of a deflector element according to a second embodiment
  • figure 6 shows the deflector element in figure 5 according to the arrow view VI in figure 5;
  • figure 7 shows a side view of a detail of the element in figure 5 according to the arrow view VII in figure 5;
  • figure 8 shows a sectioned side view of a detail of a manoeuvring shaft of a deflector element according to a further embodiment
  • figure 9 shows a sectioned side view of a single-pipe valve with a coupling, with the shutter closed and the deflector in a first position
  • figure 10 shows a sectioned side view of the single-pipe valve with the coupling in figure 9, with the shutter closed and the deflector in a second position.
  • a single-pipe valve connected to a fluid deviation coupling 2 is globally indicated with reference numeral 3.
  • This coupling 2 exhibits two connections 41, 42 for connecting to a radiator 4 to allow the delivery, for example by means of a delivery pipe 37, and the return of a fluid from this.
  • the coupling 2 is connected to the single-pipe valve 3, which also has two connections 35, 36 for connecting to input and output pipes 39, 40 of the heating fluid, and a control organ 38, which is known in itself, of a shutter 24, to control the quantity of fluid to be delivered to the radiator 4 ( Figure 1).
  • the coupling 2 exhibits a deflector organ 1, which allows the fluid from one of the pipes 39, 40, for example the input one 39, which is connected to the respective input connection 35 to be carried separately to the delivery connection 41 of the radiator, and the fluid from the return connection 42 of the radiator to be carried to the other pipe, for example to the output one 40, which is connected to the respective output connection 36 of the valve 3 ( Figures 2 and 4).
  • the fluid on-off single-pipe valve 3 comprises a valve body 32, which defines a chamber for the fluid 22.
  • said valve body 32 is provided with a valve opening 33, which is suitable for holding operating means 171, 181 and 19 in rotation of said deflector element 1 ( Figures 1, 9 and 10) .
  • valve opening 33 is suitable for holding and sealing said operating means 171 and 181 of said deflector element 1.
  • a cap 34 is provided for closing said valve opening 33 ( Figures 2 and 4) .
  • a cap 34 is provided for covering the end of the operating means 171 and 181 the deflector element 1 coming out of said valve opening 33 ( Figures 9 and 10).
  • the fluid deviation coupling 2 connected to said single-pipe valve 3 holds the connected freely rotating deflector element 1 in one of its slots 43.
  • At least one delivery opening 28 and at least one return opening 29 are provided for the fluid, and a fifth opening 27 at the end of the coupling for connecting to the single-pipe valve 3, which is suitable for acting with the deflector element 1 ( Figures 2, 4, 9 and 10).
  • Said coupling comprises a dividing separator 26 that is suitable for separating the fluid, coming out of or going into a fourth opening 15 of the deflector element 1, which is held in the slot 43 of the coupling 2, from the fluid going into or coming out of a second opening 11 of said deflector element 1.
  • said separator 26 defines and divides the portion of chamber defined by the coupling downstream of the slot 43 for the deflector element, in two separate and leak-proof pipes, which, in a first position of the deflector element 1, put the fourth opening 15 of the deflector element fluidically in communication, for example with the delivery opening 28 of the coupling 2 and the second opening 11 of the deflector element 1, for example with the return opening 29 of the coupling ( Figure 9).
  • said separator 26 defines and divides the portion of chamber defined by the coupling downstream of the slot 43 for the deflector element, in two separate and leak-proof pipes, which, in a second position of the deflector element 1, put the fourth opening 15 of the deflector element fluidically in communication, for example with the return opening 29 of the coupling 2 and the second opening 11 of the deflector element 1, for example with the delivery opening 28 of the coupling.

  • Said second tubular portion comprises a third opening 14 for said second stretch of pipe 13 set substantially level with said first end 7.
  • Said second tubular portion 12 connects by sealing to the back wall 10 and forms a fourth opening 15 for said second stretch of pipe 13 in said back wall.
  • said second opening 11 and said fourth opening 15 are set in said back wall 10 substantially in order to be able to change position, when the deflector element 1 is rotated around its X-X axis.
  • Said deflector element 1 also comprises operating means 16 or 171 or 181 for said deflector element, which are suitable for positioning said second and fourth opening 11 and 15 so as to channel a delivery fluid 17 separately from a return fluid 18.

  • said operating means for the deflector element 1 comprise a slot 16 for an allen wrench or allen key 19.
  • said operating means for the deflector element comprise a driving shaft 171 or 181, which protrudes from the first end 7 of the deflector element ( Figures from 5 to 10).
  • said driving shaft 171 or 181 is connected removably to the deflector element.
  • the driving shaft 17 or 18 is coupled to one of its ends with interference in a slot provided in the deflector element 1, avoiding blocking the passage openings 9 and above all 14 for the fluid.
  • the driving shaft 171 or 181 comprises at least one connection radius 20, preferably, for example, a plurality of connection radiuses 20, at the end connected to the deflector element 1, for creating a connection for said shaft to the deflector element, which does not obstruct the free flow of the fluid in the deflector element.
  • said at least one radius 20 is connected to a control centre 16 of the deflector element.
  • said driving shaft 171 or 181 comprises a manoeuvring end 21 suitable for being set, at least partially, outside the chamber for the fluid 22, which is defined by the single-pipe valve 3.
