Device for Adjusting gas Flow proportional to the water flow, instantaneous Water Heaters, based on a system of variable Water passing area and Derivation

摘要

Control device of gas delivery in proportion to the volume of Water consumption, instantaneous Water Heaters, in order to maintain the water temperature to a value chosen and approximately Constant, regardless of the color of Water consumption.The detection of the Water consumption is achieved with the location of Two Water Chambers separated by a combination of a Membrane and a dish with a variable step and a Water diversion of water between the two Chambers. The temperature can be varied by rotation of a Shaft increases or decreases the Water flowing through the shunt.The combination between the water flow flowing through the variable step and the Regulation of the shunt make the Membrane with the album take a Balanced position which defines the position of the Valve and the gas Flow Rate.
