DE102009003193A1 - Method for ventilating a panel radiator and panel radiator - Google Patents

Abstract

The method involves opening out the fluid channels in separated openings in a functional connection. The openings are sealed with detachable venting plugs. The fluid channels open into the surrounding area of the plate radiator (1) by releasing the venting plugs, and the heating plates are aerated. The openings are opened directly into the surrounding area by releasing the venting plugs. An independent claim is also included for a plate radiator with a sealing surface.

Description

The The invention initially relates to a method for venting a panel radiator with a connecting element between a front heating plate of the panel radiator and at least another heating plate of the panel radiator, depending a fluid channel of the heating plates, wherein the fluid channels open in separate mouths in a functional connection, and with a releasable vent plug, the the mouths closes, whereby by dissolving of the vent plug the fluid channels to a Surrounding the panel radiator open and the Heating plates are vented. Furthermore, the invention relates a set up for carrying out such a method panel radiator.

Method and plate heater of the aforementioned type are generally known under the name "serial radiator". Illustratively disclosed DE 196 14 330 C1 Such a plate heater, where the vent stopper for venting opens an orifice of the first fluid channel into the second fluid channel and an orifice of the second fluid channel to the surroundings of the plate heater.

At the initial filling rises in the heating plates of a serial Radiator the level of the heating medium at different speeds and the air is expelled at different speeds into the environment. This is z. B. also depends on how far the control valve is open and whether the circulation pump for the Heating medium during the filling and deaeration process running. When filling serial radiators of the aforementioned type with a common purpose of venting to the environment opened function connection for all hotplates flow out regularly the faster filled heating plate heating means from the functional connection, while the other hotplate still contains air.

At the Venting the known panel radiator flows regularly in the functional connection heating medium from the faster filled to the other hotplate and disturbs or prevents their complete venting.

Of the Bleed plug of a serial plate radiator In addition, it is usually not complete for venting removed from the functional connection, but only by turning dissolved in the thread. On the known panel radiator is the mouth of the first fluid channel in the second through a sliding radial seal, the mouth of the second ten Fluid channel sealed into the environment by a conical seat seal. When you release the vent plug so the Conical seat seal immediately, but the radial seal only at the complete Outlet from the mouth open.

Becomes the vent plug on the known panel radiator not far enough out of the functional connection, it remains the radial seal - unnoticed by the user - in the mouth and disturbs or prevents in turn the ventilation of the connected heating plate.
