Method for cleaning service water systems or heating installations and device for carrying out the method

摘要

A method for cleaning service water systems or heating installations to which overpressure is applied from a central supply is characterised in that a) by separation from the central supply (9) and simultaneous opening of the service water system (23) or of the heating installation, the overpressure is suddenly reduced, specifically in such a way that there is a slight evacuation against the direction of flow in operation; b) closure is performed again after a short time and the overpressure builds up; c) the operations of pressure relief and pressure application are multiply repeated successively, and d) these operations are performed under automatic control. In the device for carrying out the method, there is arranged in a main line (10) between the central supply (9) and the service water system (23) or heating installation a three-way valve (24) which can be adjusted by means of a motor (27) provided with a controller (28). <IMAGE>
