DE202005002147U1 - Radiator, esp. tubular radiator has sealing element with top bore connected to intake socket and to intake guide with intake flow deflection through 90degrees to regulator valve - Google Patents

Abstract

The radiator consists of tubular elements connected via overflows, with one element (3) having a connection socket for intake (7), another element an outlet connection socket, and an end element (4) with regulator valve. The first element is sealed relative to neighboring ones (2,a) via upper and lower sealing elements (9,10). One sealing element (10) has a bore in its head area, directed towards the intake socket. The bore is connected to an intake guide, which deflects the flow through 90[deg] in direction of the regulator valve (17). The intake flow is directed via the guide and a connection tube (12) to the regulator, and the return flow is directed via a return section in the head area between the two neighboring elements.

Description

The Invention relates to a radiator, in particular tubular radiator several at her head and foot forming an overflow opening with each other linked limbs, each with a limb in the foot area with a connecting piece for the supply and another member provided with a connection piece for the return is and integrates a control valve in an end member in the head area is.

Of the radiator is characterized by the fact that the connection of supply and return from vertical attached below and preferably almost centrally to individual members of the radiator is. Such radiators are already known. There is a connection from the flow connection by means of a bent tube to one of the end elements. There it is Connecting tube liquid-tight connected to the end element. Thus, the end element becomes part of Forward port. In the headboard of this end element sits a built-in Valve, which shuts off the flow to the actual radiator or regulates.

From the DE 43 08 336 C2 For example, a so-called mehrsäuliger heat body, with hand or thermostatic valve, which is located directly in an end member of the heat body, known, the connections for the supply and return to the foot are arranged and directed vertically downwards and between front and Return a seal is located. A similar solution is in the EP 0 862 025 A2 shown.

Another similar connection, in which the connection between the pipe and the connecting piece via a liquid-tight plug connection or a screw connection takes place directly in a lateral opening of the connection piece, is in the DE 296 10 869 U1 described. The connection piece is welded from below into a lateral opening in the hub.

at all known designs the supply connection is directly coupled with the end element, i.e. there are right and left versions of the radiator to Realization of different connection conditions required.

The The object of the invention is to provide a further solution for a central connection of a tubular radiator, the simple installation of the connection elements in universal Ensures connection where possible should, the forward and reverse inside the radiator easy to pass each other.

According to the invention this Problem solved by the features of claim 1. Further advantageous embodiments The invention will be described by the features in the appended claims.

Radiator, in particular Tubular radiator off several at her head and foot forming an overflow opening with each other associated heating elements, each with an element in the foot area with a connecting piece for the flow and another element with a connecting piece for the returns is provided and in an end element in the head area a control valve is integrated, wherein the provided with the flow nozzle element (Feed element) in the foot area is arranged and against the two laterally adjacent elements in the head and foot area sealed with sealing elements, being between the two laterally adjacent elements in the head and foot each a pipe connection consists, wherein the sealing element in the head area at the pipe circumference provided with a bore or opening directed to the flow nozzle is and to this hole a within this sealing element arranged tubular guide for forwarding of the forerunner, which the flow through 90 ° in Direction control valve directs.

Especially It is advantageous that the sealing element in the head area of the Vorlaufelementes the flow over the leadership and the connecting pipe to the control valve in the end element passes and the return over a return cross section between leads the two laterally adjacent elements in the head area.

To A special feature of the invention is that the transition between the leadership and the connecting pipe over a particularly fitting he follows. The transition but can also for a further feature of the invention over a self-sealing thread were made.

To preferred features of the invention are the connections between the sealing element in the head area and the pipe connection to the valve and the valve seat in the end element as plug-in or screw connections executed.

To special features of the invention, it is possible that the leadership in Sealing element as a tubular elbow is formed and the return cross section is the difference between the outer dimensions of the elbow and the inner diameter of the sealing element results.

It is particularly advantageous if the guide is designed in the sealing element as a molded piece with integrated pipe, the disc to at least laterally spaced from the inner diameter of the sealing element and thus releases the return cross-section.

The The invention is explained in more detail below with reference to an exemplary embodiment and associated drawings.

It demonstrate:

1 : a sectional view of a radiator with a central arrangement of flow and return and with flow,

1a : a side view of the radiator behind 1 .

2 : a sealing element in sectional view,

3 : Elements or elements of a radiator with sealing element in exploded view,

4 : another variant according to 3 with sealing element in exploded view,

5 a further variant of the sealing element in sectional view,

5a a side view of the sealing element after 5 ,

In the 1 a tubular heater is shown in longitudinal section.

The tubular radiator 1 consists of several at her head and foot 5a . 5b to form an overflow interconnected elements 2 . 3 and 4 , each one element 3 in the foot area 5b with a connecting piece 7 for the lead and another element 2a with a connecting piece 8th is provided for the return and in an end element 4 in the head area 5a a control valve 17 is integrated.

The with the flow pipe 7 provided element 3 is here preferably arranged centrally and against the two laterally adjoining elements 2 and 2a in the head and foot area 5a . 5b with sealing elements 9 . 10 is sealed, being between the two laterally adjoining elements 2 and 2a in the head and foot area 5a . 5b in each case there is a pipe connection and in the sealing element 10 in the head area 5a a connecting pipe 12 is arranged, which with the control valve 17 in the final member 4 in the head area 5a communicates. The unneeded connections of the end elements 4 are each with blind plugs 15 sealed.

The sealing element 10 is in the 2 represented and formed according to the invention in a special way. The sealing element 10 on the one hand establishes the connection for the return between the limbs 2 and 2a over the return cross section 103 safe and on the other hand, the flow is over the hole 101 , the leadership 102 (formed here as a tubular elbow), optionally a connector 104 and the connecting pipe 12 and to the control valve 17 directed. Due to the relatively large return cross section, the flow through the radiator is not hindered.

The transition between the leadership 102 and the connecting pipe 12 ( 1 ) is by means of a seal 13 and, depending on the version, via the connection piece 104 ( 2 ) sealed.

The flow of the heating medium in the radiator goes out of the 1 show, where flow and return are designated V and R.

The flow element 3 does not necessarily have to be centered or nearly centered. A lateral or almost lateral arrangement is of course also possible.

In the 5 and 5a becomes a further variant (according to claim 9) of the sealing element 10 shown. The at an angle of 90 ° running guide 102 is here in a fitting 106 introduced by drilling or produced by casting and in the sealing element 10 arranged, with the guide 106 at least laterally from the inner diameter of the sealing element 10 is spaced and thus the return cross section 103 releases.
