Patent ID: 7283913

Claim:
A method of executing a leak control system ( 1 ) comprising at least one stop valve ( 2 ) with an associated flow meter ( 3 ) arranged in the supply pipe 5 ( 4 ) of the pipe installation, and at least one stop valve ( 5 ) with an associated flow meter ( 6 ) arranged in the return pipe ( 7 ) of the pipe installation, said stop valves ( 2 , 5 ) as well as associated flow meters ( 3 , 6 ) being connected to a control box ( 8 ), characterized in that the control box comprises at least one valve monitor ( 9 ) connected to each stop valve ( 2 , 5 ) to control/record the possible state of the individual stop valve ( 2 , 5 ): open or closed, and an executer which is started by the control logics of the control box in 15 consideration of the operating conditions of the pipe installation, and which performs a given sequence of actions during which it controls/monitors the valve monitors ( 9 ), which leak control system ( 1 ), on the basis of start and execution of the sequence of actions, performs a number of measurements and data collections on the basis of which it subsequently evaluates the functionality of the stop valves ( 2 , 5 ) and/or the elasticity and/or the tightness of the pipe installation.
