GM 05.278.8DE System for connecting a radiator

Description

The invention relates to a connection fitting system which enables a universal connection of valve or compact radiators.

In addition to the well-known and widespread radiator connection types with separate flow and return units ("compact") with an external valve housing and lockshield valve, or with integrated distributor sets with flow and return connections located under the radiator ("valve"), there are also connection types with so-called ballast sets or foot valves. These connection types are characterized by the fact that the connection lines are routed at a fixed distance to or from the radiator, but with ballast sets the visually disturbing pipework can be seen above the height of the radiator, and with foot valves the control element (thermostat head) is located near the floor, making it difficult to operate. In addition, foot valves can only be used for multi-layer radiators, as the mass flow has to be routed serially through the plates. Adapters and transition angles are required for installation as a valve radiator. At least two sealing plugs are required to close the return.

The object of the invention is to develop a system for the universal connection of a radiator, which improves the previously known connection systems.

According to the invention, this object is achieved by the features of claim 1. Advantageous embodiments of the invention are contained in the associated claims 2 to 10.

The advantages to be achieved according to the invention are based, among other things, on the fact that a system for connecting a radiator through which a heat transfer medium flows has two

connecting parts which are connected to one another via a riser pipe, wherein the housings of the two connecting parts have a plurality of connection openings, firstly for the flow connection to at least one plate of a single or multi-layer radiator, secondly for the connection to the heating medium return, thirdly for receiving a connection screw for the connection to the heating medium flow or for receiving a valve insert and fourthly for the connection of the two housing parts via the riser pipe.

An advantageous embodiment of the connection fitting can result if, depending on which side of the radiator the connection parts are provided on, a lateral connection opening of the two connection parts serves either to accommodate the valve insert or the connection screw for connection to the heating medium supply line. A further advantageous embodiment of the connection fitting can result if, depending on which side of the radiator the connection parts are provided on, the upward or downward facing connection opening of the two connection parts either serves to connect to the heating medium return line for returning the heating medium, or is closed with a sealing plug.

Based on this, a preferred embodiment provides that the heating medium flow can be guided to the valve insert via the screw connection and the riser pipe and the heating medium return can be returned via the connection opening of the connection parts, which points downwards. According to a further feature of the invention, a transition piece can be inserted into this connection opening for connection to the heating medium return. On the other hand, a connection angle can be connected to the screw connection for connection to the heating medium flow, with a spacer seal being arranged between the screw connection and the connection angle.

In another preferred embodiment, however, it is provided that the

Connection as a compact radiator, whereby the upward and downward connection openings of the two connection parts are closed with sealing plugs, and if necessary when connecting the flow set - upper part
the riser pipe can be closed by a plug in the lower connection part.

The connection system according to the invention allows the radiator to be connected upside down on the right or left side. The fastening tabs are still located on the back of the radiator.

The present invention is explained in more detail below with reference to advantageous embodiments based on the accompanying drawings. In

Drawings and the associated figure descriptions reveal further features and advantages of the invention. They show

Figure 1: schematic representation of a system for connecting a radiator variant 1,

Figure 1a: Detail view "X" from Figure 1,

Figure 2: schematic representation of a system for connecting a radiator variant 2,

Figure 2a: Detail view "Y" from Figure 2,

Figure 3: Schematic representation of a system for connecting a radiator variant 3.

Figure 1 shows a radiator with a first version of a mirror-image connection set. Radiators with this set can be connected via

Head can be turned, i.e. the radiators can be connected on the left or right. The system comprises the connection parts 3, 3\ which are connected to the riser pipe 4 via the connection openings d. Internal threads are provided on the valve insert side. The housings of the connection parts also have connection openings b for the flow connection to the plate b of the radiator H. The opening c in the lower connection part 3' is provided for the connection to the heating medium return R. For this purpose, a transition piece 6 must be inserted into the housing part. The opening c in the upper connection part 3 is closed with a plug 1. The opening a in the lower connection part 3' serves to accommodate the connection screw 7 for the connection to the heating medium flow V and in the upper connection part 3 to accommodate the valve insert 2. The thermostat head can be screwed onto this (not shown). The connection angle 8 can be connected to the connection screw 7. Figure 1a shows the underside of the set in an enlarged detailed view.

Figure 2 shows a radiator with a first version of a mirror-image connection set. Figure 2a again shows a detailed view. Radiators with this set can be turned upside down, i.e. they can be connected on the left or right. The difference to the variant

I consists in the fact that a spacer seal is installed in the lower part of the fitting between the connection screw 7 and the connection angle 8.

I1 is provided. This allows different connection dimensions to be compensated. External threads are provided on the valve insert side. The screwing is done here using a union nut 10. The thermostat head (not shown) can be screwed onto the valve insert 2 using a union nut 13.

Figure 3 shows the connection option as a compact radiator with a mirror-image connection set, whereby the connection parts 3, 3" are connected via the riser pipe 4. In the downward-facing

A closure plug 1" is provided in the opening c on the bottom of the fitting and a closure plug 1 is provided in the upward opening c on the top of the fitting. If necessary when connecting the supply line fitting - upper part, the riser pipe 4 can be closed by a plug 12 in the lower connection part 3'.
