Abstract:
1. An easy-type water pressure reducing apparatus, comprising a connecting tube and a movable element wherein the connecting tube has both ends respectively equipped with an inlet end and an outlet end with a bore extending there-through; the bore has an annular seat protruding at the middle section thereon, and a smaller-diameter inlet chamber integrally extending at both sides of the annular seat thereon; the inlet chamber having oblique guide slopes defining the internal surface of the middle section can accommodate the movable element defined by an inlet port and having a spring element received therein; the inlet chamber of the connecting tube also has water-guiding vents cut thereon at the same side of the inlet end thereof, and the inlet port of the movable element has a stop block extending therein to restrict the position of the spring element thereby; the movable element also includes positioning guide blocks extending at one end edge thereon to fit into the water-guiding vents thereby, and a ringed groove with a sealing ring mounted thereto to abut tight against the internal surface of the inlet chamber, forming a back-and-forth movable positioning space there-between; the movable element has a larger-diameter water plug with a waterproof ring mounted thereto extending at the other end thereon to abut tight against the internal surface of the outlet end of the connecting tube thereby; whereby, the movable element can be pushed by the elasticity of the spring element to move towards the outlet end thereof; when the water pressure at the outlet end is larger than that at the inlet end thereof, water flow will be blocked by the water plug to generate a flushing force, pushing the movable element towards the inlet end and compressing the spring element therewith so that the water-guiding vents blocked by the movable element will gradually close up and become smaller and smaller so as to cut down the influx of the water flow and achieve the purpose of reducing and stabilizing water pressure thereby.
