WIPO Patent Application WO/2014/069021
Kind Code:
A1
Abstract:
[Problem] To achieve a reduction in size, production costs, and installation work costs, with respect to a pump facility, by further aggregating components of the pump facility. [Solution] As a result of aggregating, in a header pipe and a discharge pipe, a check valve, a water stop valve, and a water-hammer-inhibition-device function, which are provided as separate components in conventional header pipes and discharge pipes, the number of components is reduced, production costs and installation work costs are greatly reduced, and a structure-simplification-accompanying reduction in the frequency of the occurrence of failures can be anticipated, and thus maintenance cost can also be reduced.
