The connection adapter that is used for radiator

The present invention relates to a kind of in order to connect the method for adapter sealing and fixing on a radiator with one, described connection adapter has a housing that comprises two pipelines, and one of them pipeline is connected on the pipe joint that radiator becomes a mandarin with its flange connector and another pipeline is connected on the pipe joint that radiator refluxes.The invention still further relates to connection adapter itself, it is suitable for a valve, particularly a thermostat valve or a pump are connected on the radiator.In addition, the present invention relates to a kind of radiator of the connection that is suitable for adapter and comprise adapter and the system of radiator.

Two-tube connection like this is mainly used in the radiator, in the zone below become a mandarin and the reflux tube joint of radiator feeds.This mode that connects is known by so-called towel radiator (Handtuchheizk rper, towel calandria) for example, and it is packed into as radiator large-area and that be equipped with many single heating tubes in outdoor bathing place/bathroom.A specified standard is followed in the two-tube connection of this radiator usually.Therefore each pipe joint has 1/2 inch internal thread and has the spacing of 50mm.In internal thread, be screwed into plug-in unit, on plug-in unit, relend and help the locking nut converter of screwing on.The shortcoming of the connection of this known way is that at first the number of components owing to essential is many for they, thereby quite bothers in assembling, and it needs big structural volume.In order to manage the sealing of connection, adopt flax silk, teflon (Teflon) or special-purpose seal cartridge.Also known clamping ring spiral via the metal sealing connects.This known sealing seals via the screw thread or the outer wall of the pipe of mutual insertion.The assembling of this sealing is that take a lot of trouble and easy the leakage.

A shortcoming of macrostructure volume is that aesthetic impression is not good.Therefore special for the towel radiator its environment that adapts to outdoor bathing place/bathroom aesthetically be important, the attaching parts that wherein offend the eye or the thermostat valve of protrusion have a negative impact to the structure of very expensive sometimes this radiator.

The objective of the invention is now, at first provide a kind of in order to easy and reliably assembling connect the method for adapter.In addition, the objective of the invention is, a kind of small-sized and easy operating, adapter of comprising two pipelines is provided, especially for the connection of thermostat valve, it is matched with the structure of radiator in phase.Another purpose is, a kind of radiator is provided, and it is particularly suitable for using such connection adapter.

These purposes are by having the method for claim 1 feature, and the adapter with claim 4 feature reaches with the radiator with claim 13 feature.

Important basic design of the present invention is, one adapter is designed so that it has two end face flange connectors that particularly are positioned at a plane, flange connector is pressed to by means of each seal on the end face that is used as counterpart of pipe joint of radiator.Apply needed thrust via a fixture, this fixture is being to be easy to approaching and to act on the radiator on the other hand on the housing on the one hand.In known so far connection, realize the fixing of adapter via two spirals that connect, and different therewith, the firm housing of adapter is directly connected in radiator now, and compresses hermetically between adapter and radiator and be connected.Wherein seal via the sealing surface of each end face and realize, the latter can constitute arbitrarily and be provided with each other by means of sealing with being close to.According to the present invention, the active force stream that is produced by fixture is the flange by adapter by whole housing and not only.Therefore produce the very stable connection of adapter and valve that is connected or pump.

Therefore according to the present invention, end face and housing that the end face of each flange connector is close to pipe joint by means of each seal are fixed on the radiator with a fixture is removable.Wherein fixture acts on one and is connected on the parts of radiator, make by housing one active force stream takes place, this active force stream is connecting generation one thrust between adapter and the radiator, and this thrust affacts on the seal symmetrically as pre-power in this case.The active force stream of symmetry is particularly advantageous, because realized the uniform load and the sealing of pipe joint whereby.

Have many advantages according to assembling mode of the present invention, this mainly derives from can cancel needed so far locking nut: therefore, at first the assembling of adapter is especially simply and easily, its one of needs operation, particularly unique fixture, it is a come-at-able from the outside screw in a simple especially situation.Whereby, a kind of rapid and reliable assembling is possible.This fixed form provides the possibility of the plug-in unit (middleware) of saving member as needing in the past simultaneously, thereby and reduces cost and reduce structure space.Distance between adapter and the radiator can be reduced more than one centimetre by the present invention.
