Definitions

  • connection fitting according to the preamble of claim 1.
  • a connection fitting is eg from document DE-N-9421996 known.
  • Connection fittings for connecting a radiator to a heating circuit are known in various designs.
  • Connection fittings in particular valves directly connected to the heating circuit, which regulate the flow and return of heating medium to the radiator and back, usually have a fixed predetermined flow path for the flow and a fixed predetermined flow path for the return. This has the disadvantage that you can mount the valve when mounting on the on-site usually already existing nozzle of the heating only pointing in a predetermined direction or would have to cross the nozzle. Otherwise, an advantageous flow through the radiator would not exist.
  • valves in which the flow paths for the flow and for the return can be mutually changed or merged so that the valve can be mounted on the nozzles of the heating circuit and only then the flow paths of the valve are set ,
  • valves are known with which an adjustment or a change of the flow direction is adjustable during operation.
  • valves are known in which a part of the heating medium flowing into the valve flows through a specially designed, separately running channel directly and without detour via the radiator from the supply pipe to the return pipe and thus back into the heating circuit. This ensures that even when the valve position is blocked there is a constant heating medium flow and the heating circuit remains uninterrupted.
  • connection fitting of the type mentioned above is characterized in that a structurally simple way of regulating the flow or the flow paths during operation and effective shut-off of the radiator is made possible. According to the invention this is achieved in a connection fitting of the type mentioned by the characterizing features of claim 1.
  • the proposed measures make it possible to make the valve very small and compact. In addition, there are advantages through a simplified manufacturing process or by weight and material savings. The control options are also improved.
  • the features of claim 4 ensure that the flow paths for the heating medium are easily adjustable in an advantageous manner. As a result, the inflow from the heating medium to the radiator can also be prevented and a repair or replacement of the radiator is possible without affecting the heating circuit.
  • valve can be easily mounted on any side of the radiator or the connection can be made to the heating circuit in any radial direction.
  • valve or the chick are adjustable or adjustable from both sides.
  • a regulating unit is provided which is arranged in an ergonomically correct position.
  • connection fitting comprises a valve 1 and may optionally, as described below, in addition to the valve 1 include further components.
  • the valve 1 is connectable with its two terminals 13, 14 to a, in particular designed as a single-pipe system, heating circuit and connected via a further connection with a T-piece 2.
  • the radiator 9 itself has two connections, namely a radiator flow connection 8 and a Radiator return port 7. Between the T-piece 2 and the radiator flow connection 8, in particular on a connecting pipe 4, a regulating unit 3a, 3b is provided, which is either thermostatically regulated or manually regulated.
  • the regulating unit 3a, 3b can also be provided directly on the valve 1 or in the region of the T-piece 2.
  • the radiator flow connection 8 is located at the upper end of the radiator 9 and the heating medium is via the connecting pipe 4 and the regulating unit 3a, 3b via this radiator flow connection 8 into the radiator 9 fed.
  • the cooled heating medium leaves the radiator 9 via the radiator return connection 7 provided at the lower end of the radiator and flows via the T-piece 2 back into the heating circuit via the valve 1.
  • connection fitting only consists of or is formed from the valve 1 connected directly to the radiator 9 via corresponding connecting piece.
  • the valve 1 has two heating circuit side connections, namely a first port 13 and a second port 14 through which the heating medium from the heating circuit to the valve 1 and subsequently into the radiator 9 and from the radiator 9 via the Valve back into the heating circuit can flow. Which of the two connections 13, 14 is to serve as a supply connection is selectable.
  • a substantially cylindrical plug 15 which is rotatably mounted with respect to its central longitudinal or cylindrical axis 40 in a, preferably centrally located, recess or bore of the valve 1.
  • the plug 15 controls the flow paths of the heating medium from the heating circuit through the valve 1 to the radiator 9 and back or releases or blocks them.
  • the chick 15 is shown in detail.
  • the chick 15 has two mutually opposite recesses or recesses 400 of the cylindrical basic shape. Due to these recesses 400, which need not extend over the entire height range of the plug 15, a partition wall 30 is formed by the remaining cylinder body.
  • the plug 15 has two diametrically opposite, in particular circular, sealing surfaces 42 on, takes place at the predetermined positions of the plug 15 relative to the flow paths, in particular in a locking position 0 described in more detail below, a shutoff of the flow paths or in the housing partitions of the valve 1 formed flow openings.
  • two diametrically opposed, in particular convexly curved, guide surfaces 43 are formed by the recesses 400, through which the flow paths are formed or defined or limited and deflected.
  • At least one bypass opening 17 is provided, which in particular has a cylindrical basic shape, and whose central axis 50 extends substantially perpendicular to the central longitudinal axis 40 of the valve 1.
  • an open bypass connection 35 is provided, which connects the first connection 13 to the second connection 14 in a fluid-conducting or flow-related manner, almost independently of the position or position of the plug 15.
  • the size of the bypass opening 17 will be described later.
  • the valve 1 has in its with respect to the terminals 13 and 14 averted area provided for the heating flow 20 output channel 19, can flow through the heating medium through a, in particular laterally provided on the valve, outlet from the valve 1 to the radiator 9 out.
  • the valve 1 has a, in particular tubular, provided for the heating return 18 input channel 16, through the heating medium from the radiator 9 in the valve 1, in one, in particular helical or spindle-shaped wound, connecting channel 48, is fed.
  • This connection channel 48 adjoining the plug 15 has a fluid-conducting connection to the second connection 14 and can be regarded as a partial region of the second connection 14. From there, the heating medium returns to the heating circuit.
  • the two channels 16 and 19 are in the embodiment according to the invention advantageously constructively designed so that the input channel 16 is at least partially in the output channel 19 and is at least partially enclosed by this.
  • Such a design is particularly space-saving. It is advantageous if the output channel and the input channel 16 have a common central axis 45.
  • a first flow position (I) by a rotation of the plug 15 is reached from the zero or locking position (0), starting in the clockwise direction, the chick 15 is in the present embodiment so that the following flow paths are permitted:
  • the heating medium passes through the acting as a supply port first port 13 on the chick 15th
  • the heating return 18 passes through the input channel 16 back into the valve 1 and leaves via the plug 15 and the connecting channel 48 via the second port 14, the valve 1 and flows back into the heating circuit.
  • a constant Rothfluidstrom flows through the bypass connection 35, from the first port 13 through the bypass port 17 via the second port 14 back to the heating circuit.
  • the bypass opening 17 is dimensioned such that in the first flow position I and in the second flow position II 40 to 70%, in particular 45 to 60%, preferably about 50%, of the heating medium flowing into the valve 1 through one of the ports 13 or 14 through the Bypass opening 17 flows back into the heating circuit without entering the radiator 9.
  • optimal distribution of the heat stored in the heating medium is ensured on the radiator of the heating circuit and the heating circuit itself.
  • the dimensioning of the bypass opening 17 is dependent on the size of the radiator, the number of connected to the heating circuit radiator and other factors and can be interpreted accordingly, knowing these parameters, i. Different chicks 15 with correspondingly large bypass openings 17 can be inserted into the radiators 9.
  • the dimensions of the bypass openings 17 in the individual radiators 9 of a single heating circuit can differ in such a way that For example, for the first radiator of a monotube heating circuit, a chick 15 is selected with a larger bypass opening 17 than for the last or the more rear connected radiator 9 of the heating circuit, in which a smaller bypass opening 17 may be necessary to this radiator 9 still enough to be able to supply thermal energy.
  • the heating medium should always leave the valve 1 through the outlet channel 19 as a heating flow 20 in the direction of radiator 9 and should always flow back as a heating return 18 from the radiator 9 via the inlet channel 16 into the valve 1.
  • This ensures that the heating medium always flows into the same connection of the heating element 9, namely advantageously the radiator feed connection 8, independently of the direction of flow in the heating circuit.
  • the inflow into the radiator 9 could be reversed, but this is unfavorable for heating considerations, since the heating power of the radiator is reduced.
  • the flow direction in the first port 13 or in the second port 14 changes depending on the position of the plug 15. This ensures that the valve 1 can be placed on the on-site usually preassembled nozzle, regardless of the predetermined in the heating circuit flow direction of the heating medium. That is, the valves 1 can be mounted without knowledge or consideration of the flow direction without having to cross over pipes.
  • the plug 15 In the blocking position (0), the plug 15 is positioned so that the sealing surfaces 40 obstruct the entrance to the outlet channel 19 and the connection between the inlet channel 16 and the connections 13 and 14. That is, the fluidic connection of the first terminal 13 and the second terminal 14 with the output channel 19 and with the input channel 16 is no longer given.
  • indicia in the form of arrows 23, 24 are provided, which indicate the direction of the flow and after which the position of the plug 15 can be made.
  • connection fitting further comprises in the embodiment according to the invention a T-piece 2, which is fluidically connected to the outlet channel 19 and the inlet channel 16 of the valve 1.
  • This T-piece 2 ensures that the heat flow from the valve 1 spatially separated from the heating return 18 20 is passed to the radiator flow connection 8 of the radiator and that the heating return 18 passes separately into the inlet channel 16 of the valve 1.
  • a tubular element 12 is provided in the T-piece 2, which in particular has the same diameter as the input channel 16 and is in direct flow communication therewith or, in particular tight, connected or connectable to this.
  • This tubular element 12 can advantageously be designed such that it projects at least partially through the radiator return connection 7 of the heating element 9 into the heating element 9.
  • Fig. 7a and 7b The tube element 12, the inlet channel 16 and the outlet channel 19 have a common central axis 45. This ensures that the valve 1 relative to or relative to the rigidly arranged in this embodiment T-piece 2 about this central axis 45 is rotatable or pivotable. This is important during installation or during assembly, since it is unimportant by this structural design, whether the valve 1 and the T-piece 2 are located to the left or right of the radiator 9.
  • the pivoting of the valve 1 relative to the T-piece 2 and the radiator 9 is also advantageous for the reason that thereby the connection to the heating circuit perpendicular to the axis 45 in any radial directions or angular position, preferably down into the ground or after behind the wall or at an angle, can take place or a connection to projecting from the wall on-site connections can easily be made.
  • the chick 15 and / or the T-piece 2 are substantially symmetrical with respect to a center plane 55 of the valve 1 perpendicular to the central longitudinal or cylindrical axis 40 of the chick.
  • the chick 15 is accessible from both sides of the center plane 55 and can also be switched or adjusted from both sides. This ensures maximum connection variability.
