Z Connection fitting for panel radiators

I The innovation concerns a connection fitting for panel radiators in the form of a fitting arranged at the bottom.

i body with flow and return connections.

Such integrated connection fittings are located next to the radiator or, in the case of double-layered panels, between them.

I' sen both. A piece of pipe leads from the flow connection to an upper connection part . The valve body is assigned to this. A return connection, on the other hand, opens into a lower connection part.

Since sealing seats are made of brass or gunmetal for corrosion and machining reasons, this material is used both for the lower valve body and for the upper connecting part. This results in many machining steps and there are relatively many connections between the special material and the other steel parts, namely both in the lower valve and in the upper valve area.

I The connection fitting is to be made considerably simpler and cheaper . The processing steps and the connections between the special material and steel are to be reduced to a minimum.

\ The new connection fitting is characterized by a

I valve body acting directly on its return connection.

In contrast to the previously known ¹ connection fittings of this type, the fitting body and the vehicle body are now combined into one unit. Only the fitting body has to be made from the special material and machined. The connection of different materials is also limited to this fitting body. In addition, the parts are extremely simple in construction. The entire connection fitting is considerably simplified and cheaper thanks to the new design.

To convert from a one-pipe connection to a two-pipe connection, an adjustment device in the valve body was previously required, which also had to be machined. In the new valve body, a removable closure can be provided between the flow and return connections. This can be designed as a partition wall that is laid out when required. It can also be designed as a removable plug. Additional sealing to the outside is not required, as the closure is integrated in the valve body and is accessible from the return connection and sealed by the valve body attached here.

The attached drawing shows an example of the innovation. It shows:

Fig. 1: A vertical section through a connection fitting with pressure difference from the outside to the valve body,
Fig. 2: A longitudinal section through a valve body

with pressure difference from the inside on the valve body and Fig. 3: A section from Fig. 2.

In the lower part of a panel radiator 1, a fitting body 2 with a flow connection 3, a return connection 4, a flow connection 5 and a return connection 6 is arranged. From the flow connection 5

a pipe section runs to an upper connection part . Since there are no sealing seats, this is made of steel. No machining is required and there is a simple steel-shell connection. The return connection 6 ends in a lower connection part 9. The valve body 10 is directly assigned to it. Only the return connection 6 needs to be machined on the front side and connections between different materials are only created on the valve body 2.

Between the flow and return supports 3, 4 of the valve body 2 there is a closure 11 in the form of a partition wall that can be drilled out or a removable plug. After removing this, the connection valve can also be used for a single-pipe connection. Access to the closure 11 is tightly closed by the sealed valve body 10.

Claims (3)

Buderus Aktiengesellschaft G 16-412 TT/P -f/di- Protection claims 1. Connection fitting for panel radiators in the form of a fitting body arranged at the bottom with flow and return connections, characterized by a valve body (10) assigned to the fitting body (2) and acting directly on its return connection (6). 2. Connection fitting according to claim 1, characterized by a closure (11) removably arranged between the flow and return connection (3,4) of the fitting body (2). 3. Connection fitting according to claim 2, characterized in that access to the closure (11) is closed by the sealed valve body (10).
