PURPOSE:To highten operability by providing a hot water and cold water mixing stopcock comprising a hot water valve and a cold water valve which are disposed on both sides of an oblong body, a measuring valve, a blade wheel for rotating the measuring valve with mixed water, and an open-and-close valve portion for simplifying the structure of the stopcock. CONSTITUTION:An oblong body A includes a hot and cold mixed water path 3 and a hot water path 1 and a cold waterpath 2 which are formed on both sides of the path 3. A hot water valve (a) and a cold water valve (a') which are opened and closed by handles 5, 5' are disposed on right and left sides of the body A, and nonreturn valves (b), (b') are disposed on the downstream side of the respective valves (a), (a'). The mixed water path 3 is divided at the midway portion into a main path 3a and a by- pass path 3b which are connected to the same outlet 16, and a measuring valve (c) and a manually-operated open-and-close valve (not shown) are disposed in each of the paths 3a, 3b. The measuring valve (c) comprises a measuring function portion c1 having a water volume setting cam 17, a speed reducing gear train 18 and a blade wheel 19 and an open-and-close valve portion c2 having a valve seat 20 and a valve body 21, whereby mixed water of controlled temperature is discharged from a discharge tube 52. |
