Abstract:
1. A water discharging method applied in a hydrant apparatus, comprising: opening at least one switch of the hydrant apparatus to prepare for supplying water flow; and providing temperature control means to determine whether the temperature of the water flow is beyond a predetermined range or not at the moment when the hydrant apparatus is opened and then to intercept the water flow to prevent the water from flowing out of the hydrant apparatus if the temperature is beyond the predetermined range and to have the water flow out of the hydrant apparatus if the temperature is within the predetermined range; wherein the temperature control means sense the temperature of the water flow after water flows out of the hydrant apparatus; and then adjust the amount of the water flow of the hydrant apparatus along with the variation of the temperature of the water flow and reduce or intercent the water flow of the hydrant apparatus when the temperature is beyond or below the predetermined range.
