Definitions

• This invention relates to a 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 with shut-off inserts or valves arranged in the interior of a multi-row radiator, 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.
• 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.
• 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.
• a shut- off insert with a closing element can be introduced into the connecting element.
• 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.
• the shut-off element is provided with corresponding vent holes, through which the air can stream out through the sealing plate.
• 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.
• 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.
• 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.
• 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.
• 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.
• the purpose of the invention is to improve the connecting elements used for multi-row radiators and to introduce a radiator with such a connecting element.
• the shut-off or control inserts integrated in the connecting elements should be manufacturable particularly easily and inexpensively while another objective is to improve the process of controlling the flow of the heating medium through the radiator, in particular in case of the multi-row plate radiator with inlet and outlet ports for the heating medium and usually with the first fully passable heating plate facing a heated room / space with at least one other heating plate that is arranged in a row behind it and said heating plate being designed for the intended reduction of the heating medium flow for cutting down or controlling the heating output.
• the connecting element for connecting two heating plates of the radiator consists of lateral connecting sockets and of the first threaded connecting bushing which is usually installed in the return branch of the heating system, said components being arranged to form a T-shaped casing located around a central spherical part of the connecting element, characterized in that the second threaded connection bushing for the valve shaft is attached across the plane of the intersections of the principal axes of the connecting sockets and of the first threaded connection bushing, said valve shaft extending sealed into the central spherical part of the connecting element with its with the radial recess or other adaptation provided cylindrical obturator, for which a cylindrical seat is formed with its lateral holes emptying into the lateral connecting sockets and into the threaded connection bushing.
• the invention ensures the achievement of the desired versatility and ease of manufacturing of the aforementioned connecting element whose essential design consists in the solution that it is designed in the way that the cylindrical seat consists in a cylindrical distributing tube with side holes that penetrates, in a sealed manner, through the second threaded bushing up to the opposite inner wall of the central spherical part, the correspondingly shaped protrusions of the tubular fittings being fitted to the body of the distributing tube through the connecting sockets tightly embedded into these connecting sockets.
• the contact fitting sections of the distributing tube with the protrusions and the opposite ends of the elements of this system in contact with the body of the connecting element are interconnected by overlapping, resistance welding or brazing, and / or combinations of these methods.
