Abstract
A hydrant apparatus comprises at least an outlet pipe, at least a switch for controlling the water flow, and at least a temperature limiting component. The outlet pipe is used for flowing water out of the hydrant apparatus. The switch, coupled to the outlet pipe, is used for controlling the water flow and adjusting the temperature of the water flow. The temperature limiting component limits the temperature of the water flow inside a predetermined range.
Claims8
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.

A hydrant apparatus, comprising:
- at least an outlet pipe for flowing water out of the hydrant apparatus;
- at least a switch coupled to the outlet pipe for controlling the water flow or adjusting the temperature of the water flow, or both of controlling and adjusting the water flow;
- and
- at least a temperature limiting component that limits the temperature of the water flow within a predetermined range;
- wherein the temperature limiting component is provided on the switch;
- wherein the temperature limiting component is a movement limiting structure having at least one rail and the rail is used to limit the movement of the switch.
