Apparatus for decalcifing water by producing turbulence |
摘要 |
An inlet nipple and a housing having a water passage extending therethrough that have first, second and third water bore portions of progressively larger diameters in a downstream direction. A variable throttle point is formed by a fixed member and a movable member acting in conjunction with the bore portions that produce a turbulent flow causing cavitation downstream of the throttle point independently of the quantity of flow. In one embodiment the movable member includes a closure portion seatable against a seat formed at the intersection of the bore portion and an annular portion that in conjunction with a bore portion forms an annular water flow space downstream of the closure portion. In the second embodiment the fixed member has a closure portion converging toward an aperture in the movable member which is in the shape of a cup. A filter insert is secured to the housing to collect precipitated material while a layer of galvanically soluble metal is provided on the movable member to have water flow thereover.
