The change of the water service pipe network directly affects the valve closing scheme library, and the valve closing scheme library is completely feasible to be reconstructed at intervals because the conventional change period of the water service pipe network is not large. The valve closing analysis method provided by the application can be applied to all fluid pipe network systems, and if the pipe network change period is short in a special fluid operation pipe network, the change period is required to be ensured to be not less than the construction time of the valve closing scheme library.
