Abstract

The method involves attaching a plate radiator to a supply of a build-lateral heating system by a supply connection (2). A return connection (3) attaches the plate radiator to a return part of the heating system. A distributor fitting (1) connects a front plate of the radiator with the supply connection. A detachable drainage plug locks drainage at the distributor fitting, and locks a passage between the supply connection and the return connection in the distributor fitting. The passage is opened first by loosening the drainage plug, and after that the drainage is opened.

Description

The The invention first relates to a method for dewatering a panel radiator with a distributor set, the a flow connection for connecting the panel radiator to a flow of an on-site heating system and a return connection for connecting the panel radiator to a Return of the heating system has, and a front panel of the plate radiator with the flow connection and a Heating plate of the plate radiator connects to the return port, and with a detachable drain plug that on the one hand, a drainage opening on the distributor set and on the other hand, a passage in the distributor set between closes the flow connection and the return connection, wherein by releasing the Entwässerungsstopfens one hand the drainage opening and the other Openable passage and the plate radiator drainable is. Furthermore, the invention relates to such a panel radiator.

Panel radiators of the aforementioned type are generally known under the name "serial radiator". DE 295 11 076 U1 discloses such a plate heater with screwed into the distributor set drain plug with a disc-shaped "locking portion" for closing the passage. To drain the known panel radiator, the drain plug is unscrewed from the distributor set.

As soon as when unscrewing the drainage plugs of the known Panel heater is dissolved, the heating medium begins to get out of the panel radiator. To the stream the heating medium during dewatering of the known panel radiator To regulate, the drain plug is usually only slightly detached and otherwise remains in the distribution set.

This widely used methods include the risk that the passage between supply and return connection not or only incompletely opened because of Locking section unnoticed in the passage remains. Will the like incomplete dewatered panel radiators subsequently separated from supply and return of the heating system, so penetrates the remaining heating medium - for the User of the known Plattenheiz body unexpectedly - unhindered from the supply or return connection to the environment where it regularly causes significant damage.

In an advantageous embodiment of an inventive Panel radiator has a screw thread of the drain plug, which is screwed into the reducer, at least an axially permeable cross section. By the Cross section, the panel radiator already drained when the drain plug is just loosened, but not yet complete from the reducer is unscrewed.

Preferably, a radially acting sealing element is attached to a plate heater according to the invention to the drain plug, which closes the passage tight. Thus, a double fit between the abutting edge of the Ent wetting stopper in the reducer and the passage avoided.

embodiment

The Invention will be described below with reference to embodiments explained. Show it

1a a first distributor set of a panel heater according to the invention,

1b a section of the first distribution set,

1c another section of the first distribution set

2 a section of an alternative distributor set,

3a a section of the first distributor set with reducer and drain plugs,

3b a perspective view of a detail of the first distribution set and

3c a cut of this detail.

The in the 1a . 1b and 1c shown first distributor set 1 a plate heater according to the invention, not shown, has a flow connection 2 for connecting the panel radiator to a likewise not shown flow of a on-site heating system and a return port 3 for connecting the panel radiator to a return of the heating system.

The distributor set 1 connects starting from the flow connection 2 the flow through a pipe socket 4 with a front panel and starting from the return port 3 the return via another pipe socket 5 with a middle heating plate of the panel radiator. The front panel, with the distributor set 1 connected middle heating plate and another (rear) heating plate of the plate heater are not shown.

Between the pipe socket 4 . 5 is in the distribution set 1 a substantially cylindrical insert 6 fitted with a radial bore 7 to the flow connection 2 and an adjoining axial bore 8th to the front panel. To a screw hole 9 with a not shown half inch internal thread for screwing a (only in the 3a . 3b and 3c shown) reducer 10 indicates the use 6 a passage 11 on.

At the to the supply connection 2 directed radial bore in the insert 6 is a piece of pipe 12 attached, that on its outer lateral surface 13 in the distributor set 1 is tightly fitted. From the flow so the heating medium essentially only through the pipe section 12 and pour the holes into the front panel.

To the return port 3 indicates the use 6 at its outer periphery a flattening, so that the heating medium from the middle heating plate through the distributor 1 to the return connection 3 and in the return of the heating system or to the screw hole 9 can flow.

The in 2 in a sectional view corresponding to the section in 1c through the first distributor set 1 illustrated second distributor set 14 differs from the former only insofar as that to the radial bore 15 set pipe section 16 to the flow connection 17 is flared.

3a shows again the first distribution set 1 in a sectional view accordingly 1c , where in the screw hole 9 the reducer 10 with a drain plug 18 is used. The substantially tubular reducer 10 and the drain plug 18 are in 3b in a perspective view and in 3c shown again as a detail.

The reducer 10 points outside at the bottom 19 initially a half-inch external thread 20 for screwing into the screw opening 9 the distributor set 1 on, to which a groove 21 and an external thread 20 radially superior collar 22 followed. Above the collar 22 is a hexagon 23 and above it at the top 24 a tubular receiving socket 25 formed for a cap, not shown.

At the upper end 24 has the reducer 10 a holding area 27 with larger cross section and an internal thread, not shown. Between the cross sections of the drainage opening 26 and the holding area 27 has the reducer 10 a funnel-shaped transition region 28 on.

A lower half 29 of the drainage plug 18 with a constant circular cross section penetrates the drainage hole 26 of the ornamental ornament 10 and - in the assembled and closed state - the passage 11 the distributor set 1 , At the bottom half 29 points the drain plug 18 two grooves, not shown, in each of which a sealing ring 30 . 31 from a Elastomer is inserted. The sealing rings 30 . 31 seal the drainage opening 26 and the passage 11 fluid-tight.

Center points the drain plug 18 a square 32 with rounded corners on which segments of an external thread are formed. With this external thread is the drain plug 18 in the holding area 27 of the ornamental ornament 10 screwed. Between the square 32 and the internal thread of the reducer 10 are thus four circular section-shaped cross-sections are formed. The corners and external thread of the drain plug 18 as well as the flow-through cross sections are not shown.

At the upper end 33 points the drain plug 18 a square 34 for opening or closing the drainage opening 26 through passage 11 by means of an open-end wrench, not shown.

When mounting the panel heater according to the invention is the reducer 10 with the drain plug 18 as a preassembled module in the screw hole 9 the distributor set 1 screwed. At the same time the drain plug closes 18 the passage 11 the distributor set 1 ,

For dewatering the panel heater according to the invention is the drain plug 18 from the reducer 10 screwed. Here is the drain plug 18 first the passage 11 between flow connection 2 and return port 3 the distributor set 1 free. When further unscrewing gives the upper sealing ring 30 an annular drainage cross section of the drainage opening 26 free. The heating medium from the front panel and the rear heating plates of the panel heater can then from the distribution set 1 through the drainage cross section and the flow-through cross sections between the drainage plug 18 and the internal thread of the reducer 10 flow out.
