Abstract
PURPOSE:To offer a constant proportion mixing valve, which is to hold always the mixing proportion of two types of fluid, such as hot and cold waters, regardless of the amount of incoming fluid supplied from respective ducts by regulating the pressure difference constant between the hot water pressure in a line connecting two valve devices and the warm water pressure in a duct at the underflow of the valve device. CONSTITUTION:Drop of warm water pressure in a duct 4 at the time of a valves 7b opening this duct 4 yields pressure difference between the valve 5a side and opposite side of a diaphragm 5b, which will be displaced downward according to this pressure difference. Then the opening of the duct 4 is increased by the valve 5a, and warm water pressure in the duct 4 at the underflow of valve device 5 is raised. Thus, the pressure difference between hot water pressure in the duct 1 connecting two valve devices 3, 7 and the warm water pressure in the line 4 at the underflow of valve device 5 is held constant, and thereby the mixing proportion of fluids from duct 1, 4 can be maintained always constant.
