Description

Universal connecting element providing connection of two heating radiator plates Field of the Invention This invention relates to a universal connecting element providing connection of two heating radiator plates, wherein said connecting element consists of composite connecting and attaching cylindrical components and attaching bushings to form T-shaped casings in their inner part with arranged shut-off inserts or valves for a multi-row radiator therein, in particular for the multi-row plate radiator when importance is given on a higher heating output of its front plate facing the heated room / space
Description of the Prior Art
Connecting elements providing connection of two heating radiator plates are themselves known. The document DE 101 35 215 CI describes a heating plate radiator consisting of at least two heating plates. Here, the centre holes of the heating plates that are mutually offset are assigned in the longitudinal direction individually in angle or as T-shaped casings, connecting and attaching sleeves that are composed of spherical sections with connecting sockets. The flow distribution inside the attaching and connecting sockets makes sure that the heating medium seamlessly streams from the inlet into one of the heating plates and from other heating plate again to the outlet.
DE 299 80 186 Ul also describes a multi-row radiator with connecting elements. A shut- off insert with a closing element can be introduced into the connecting element. To enable the shut-off insert to carry out the function of a venting member, the end of the shut-off insert situated in the neck comprises a sealing plate with a through hole, which is closable by a sealing component carrying a spindle. On its front side, the shut-off element is provided with corresponding vent holes, through which the air can stream out through the sealing plate.
One example of approach that consists in preferring higher heating output of the front heating plate facing a heated room at a multi-row heating plate radiator, is known from the published patent application (PV 1998-2158), according to which the relevant double-row or multi-row heating plate radiator is preferably provided with a single inlet port, which is connected only with the front heating plate facing the heated room. The heating medium, which flows through this inlet port, is distributed along the upper edge of the front heating plate and by means of suitably dimensioned feeding channels situated perpendiculary to them and that are preferably equally spaced in the frontal area facing the heated room. Regardless of whether the radiator is operated at full or partial load, the heating medium is in that way primarily supplied to the front heating plate and subsequently to the remaining heating plates of the multi-row heating plate radiator. Consequently, the front radiator plate with the same heating output will be warmer, thus presenting more pleasant touch feeling than existing systems. Preferably, this advantageous effect is even intensified by the fact that the front heating plate features a higher radiation ratio.
To facilitate the flow of heating medium from the front heating plate to at least one subsequent heating plate or similar item that are positioned behind it, at least one connecting element or possibly a tube is arranged in the system, and said connecting element is preferably situated at the bottom front corner area of the frontal radiator heating plate, from which then the partly cooled-down heating medium flows into the lower part of the second heating plate situated behind it or possibly into the subsequent plate in the case of the multi-row heating radiator. Regarding this second heating plate, the heating medium is supplied at first upwards to the upper longitudinal edge of the second or possibly the subsequent heating plate, where the liquid is again directed through the upper distribution channel provided, then it is supplied by means of perpendicularly attached flow channels to its second lower corner area with a connected outlet port. In such a arrangement, it is supposed that the heating medium transfers the greater part of its heat to said front heating plate, while entering, already partially cooled down, the second or subsequent heating plates, ensuring, in such a way, a reduced heating output.
The obvious drawback of this arrangement is that the control of the reduced heating output of the second or subsequent heating radiator plates of the multi-row heating unit can not be done. Another drawback of this solution consists in the fact that if compared with standard solutions of the multi-row heating radiators, where the hot heating medium streams equally in all heating plates to be cooled down, the heating output of the entire heating plate radiator is generally lower because the hot heating medium flows into the front heatmg plate at first while a second or subsequent heating plates are supplied with already cooled- down heating medium, thereby reducing the heating output of the second and possibly subsequent heating plates. In terms of a controlled streaming of the heating medium into the multi-row heating radiator and with regard to the specific conditions in its partial load mode and in order to comply with achievable heating output and to increase comfort in the heated space and especially to improve the control possibility, a solution was proposed (WO 2009015706), which uses another valve in combination with one of the upper connecting elements that are connected to the inlet port of the heating medium, by means of which it is possible to direct the mass flow of the heating medium to the second rear heating plate through an overflow connection, and the used connecting element is provided with an internal screen.
A disadvantage of the solution consists in using an overflow connection or overflow coupling, which significantly complicates and increases the production cost of multi-row heating radiators of such a design, and moreover, it causes problems with radiator cleaning for the end-user, and therefore the mentioned solution did not prove enough in practice.
Nature of the Invention

For most variants of the connecting element in terms of its various functions, it is advantageous according to the present invention that the barrier segment is provided with a blind orifice oriented perpendicularly to the stabilizing sealing flange, said blind orifice emptying in the body of the barrier segment as a planar seat created for fitting distributing or closing elements, or parts thereof.
According to the present invention, the barrier segment of the universal connecting element featuring a three-way valve function is preferably provided with three radial holes emptying into its blind orifice and with the radial cut-out that is arranged at the same level with the rest of the circular segment with inwardly extending pivotable poppet stem of the valve shaft.
According to the present invention, the barrier segment of the universal connecting element with the venting function is provided with two radial holes emptying into the blind orifice and with a transversal channel arranged at the same level with the downstream axial channel at the hollow poppet extending inwardly with the venting group located at the end of its control shaft. According to the present invention, the barrier segment of the universal connecting element with the venting function is provided with one radial hole emptying into its blind orifice and with an internal channel directed from the opposite side of the common tube, which open both together with the blind orifice at the forehead level of the stabilizing sealing flange to realize the function of the distributing, closing or venting element, etc.
