Title
(DE) VERFAHREN UND VORRICHTUNG ZUM ZEITWEILIGEN VERSCHLIESSEN EINER FERNWÄRME-ROHRLEITUNG
(EN) METHOD AND DEVICE FOR THE TEMPORARY CLOSURE OF A DISTRICT HEATING PIPELINE
(FR) PROCEDE ET DISPOSITIF DE FERMETURE TEMPORAIRE D'UNE CANALISATION DE CHAUFFAGE URBAIN
Abstract
(DE)
Zum zeitweiligen Verschließen einer mit einem Rohrleitungsfluid und insbesondere mit heißem Wasser gefüllten Fernwärme-Rohrleitung (10) , in die in vorbestimmten Abständen Absperrarmaturen (11) fest eingebaut sind, wird zumindest eine der Absperrarmaturen geschlossen. Zusätzlich wird unmittelbar stromauf der geschlossenen Absperrarmatur eine elastisch expandierbare Absperrblase (13) in die Rohrleitung eingebracht und mit einem Druckmedium, insbesondere Wasser gefüllt und expandiert. Die Absperrblase liegt im expandierten Zustand auf ihrer dem Rohrl ei tungs fluid abgewandten Seite an der Absperrarmatur an und ist dichtend gegen die Innenwandung der Fernwärme-Rohrleitung gespannt, wobei sie im expandierten Zustand an der Absperrarmatur anliegt.
(EN)
For the purpose of temporarily closing a district heating pipeline (10) filled with a pipeline fluid, particularly hot water, in which shut-off valves (11) are permanently installed at predetermined intervals, at least one of the shut-off valves is closed. In addition, an elastically expandable shut-off bladder (13) is introduced into the pipeline directly upstream of the closed shut-off valve and is filled with a pressure medium, in particular water, and expanded. On its side opposed to the pipeline fluid, the shut-off bladder bears in the expanded state against the shut-off valve and is braced in a sealing manner against the inner wall of the district heating pipeline.
(FR)
L'invention concerne la fermeture temporairement d'une canalisation (10) de chauffage urbain remplie d'un fluide de canalisation et notamment d'eau chaude, dans laquelle sont solidement montés des appareils de sectionnement (11) à des distances prédéterminées. A cet effet, au moins un appareil de sectionnement est fermé. De plus, un élément gonflable d'obturation (13) expansible élastique est monté dans la canalisation directement en amont de l'appareil de sectionnement fermé, est rempli d'un agent de pression, notamment d'eau et est dilaté. A l'état en dilaté, l'élément gonflable d'obturation est en contact, par son côté opposé au fluide de canalisation, avec l'appareil de sectionnement et est tendu de manière hermétique contre la paroi interne de la canalisation de chauffage urbain.
