A device for the maintenance of the pipes, in particular, the descaling and deoxidation.

摘要

The device for cleaning a network of bathroom pipes comprising a pump (4) for circulating a cleaning fluid (16) and a piping network (18), comprises valves (7) connected to inlets and outlets of the pipes, a pH meter to measure the pH of the cleaning fluid, a main valve to control the water inlet in the piping network, a filtration unit, and a fluid injecting zone. The valves are controlled individually to form a closed circuit, whose configuration is variable. The cleaning fluid is an acid solution injected in the network. The pH of the fluid is measured in upstream of the injection zone. The device for cleaning a network of bathroom pipes comprising a pump (4) for circulating a cleaning fluid (16) and a piping network (18), comprises valves (7) connected to inlets and outlets of the pipes, a pH meter to measure the pH of the cleaning fluid, a main valve to control the water inlet in the piping network, a filtration unit, and a fluid injecting zone. The valves are controlled individually to form a closed circuit, whose configuration is variable. The cleaning fluid is an acid solution injected in the piping network. The pH of the fluid is measured in upstream of the injection zone, and adjusted by injecting the cleaning fluid or by introducing water in the closed circuit. The filtration zone is placed in upstream of the injection zone and in downstream of the pH meter. An independent claim is included for a process for cleaning the pipes.
