Title
(EN) FLUSHING RIG
(FR) APPAREIL DE RINÇAGE
Abstract
(EN)
The invention concerns a flushing rig (10) for use in flushing a pipework system such as a heating or cooling system. The flushing rig (10) comprises: an inlet port (12) connectable to the pipework to be flushed; an outlet port (36) connectable to the pipework to be flushed; a pump (16) configured to propel water from the inlet port to the outlet port; a filter vessel (42a,b) connectable via a valve arrangement (24a, 24b, 32a, 32b) between the inlet port and the outlet port, the filter vessel containing a filter (42) for filtering water passing through the filter vessel; and a bypass passage (26) incorporating a bypass valve (28), so that when the bypass valve is open water is able to flow from the inlet port to the outlet port without passing through the filter vessel.
(FR)
L'invention concerne un appareil de rinçage (10) destiné à être utilisé dans le rinçage d'un système de tuyauterie tel qu'un système de chauffage ou de refroidissement. L'appareil de rinçage (10) comprend : un orifice d'entrée (12) pouvant être relié à la tuyauterie à rincer ; un orifice de sortie (36) pouvant être relié à la tuyauterie à rincer ; une pompe (16) conçue pour propulser l'eau à partir de l'orifice d'entrée vers l'orifice de sortie ; un récipient de filtre (42a,b) pouvant être relié par l'intermédiaire d'un agencement de soupapes (24a, 24b, 32a, 32b) entre l'orifice d'entrée et l'orifice de sortie, le récipient de filtre contenant un filtre (42) pour filtrer l'eau passant à travers le récipient de filtre ; et un passage de dérivation (26) incorporant une soupape de dérivation (28), de sorte que lorsque la soupape de dérivation est ouverte, l'eau peut s'écouler à partir de l'orifice d'entrée vers l'orifice de sortie sans passer à travers le récipient de filtre.
