Claims

[Claims for Utility Model Registration] (1) A valve body for opening and closing a flow path provided in a valve box, a spindle for opening and closing the valve body with an opening/closing handle connected to one end, and a valve body provided in the flow path for opening and closing the valve body. a water storage amount detector that integrates the number of rotations of the impeller and the impeller to detect the amount of water flowing from the start of water flow, a valve closing mechanism that can bias the spindle in the valve closing direction, and a water storage amount setting. and a comparison means for comparing the detected value of the water storage amount setting device and the set value of the water storage amount setting device, and operating the valve closing mechanism to close the valve when the detected value is equal to or higher than the set value, the comparing means 1 is a fixed-rate water stop valve with variable water storage capacity that compares the detected value with the set value set by the water storage volume setting device at the time of the comparison.
