Abstract
An easy-type water pressure reducing apparatus comprises a connecting tube having a bore extending through an inlet end and an outlet end. The bore has an annular seat with a smaller-diameter inlet chamber integrally extending at both sides to which a movable element with an inlet port to receive a spring element is mounted.
The movable element also includes positioning guide blocks to fit to water-guiding vents of the inlet chamber, and a ringed groove with a sealing ring to abut tight against the inlet chamber, forming a back-and-forth movable positioning space there-between. Therefore, when water pressure at the outlet end is larger than that at the inlet end, water flow blocked by a water plug of the movable element will push the movable element towards the inlet end, compressing the spring element and closing the water-guiding vents gradually to reduce the water flow and stabilize the water pressure thereby.
The movable element also includes positioning guide blocks to fit to water-guiding vents of the inlet chamber, and a ringed groove with a sealing ring to abut tight against the inlet chamber, forming a back-and-forth movable positioning space there-between. Therefore, when water pressure at the outlet end is larger than that at the inlet end, water flow blocked by a water plug of the movable element will push the movable element towards the inlet end, compressing the spring element and closing the water-guiding vents gradually to reduce the water flow and stabilize the water pressure thereby.
Claims (9)
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.
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.
2. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the inlet end of the connecting tube is defined by internal screw threads, while the outlet end thereof is defined by external screw threads thereof.
3. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the water plug of the movable element has an annular groove defining thereon to which a waterproof ring is mounted.
4. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the water plug thereof has the end surface defined by an arcuate grooved area.
5. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the conjoining edge of the bore and the inlet end of the connecting tube has a stop seat extending thereon, to which a watertight washer is mounted.
6. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the stop block of the movable element is molded in crosswise configuration with multiple orifices extending there-through to fluidly communicate with the inlet port thereof.
7. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the movable element has one end edge defined by an oblique guide surface extending along the positioning guide blocks thereon.
8 8. The easy-type water pressure reducing apparatus as claimed in Claim 1 wherein the inlet chamber of the connecting tube is equipped with a bottom surface having a conically-tapered abutment portion protruding thereon, and the inlet port of the movable element also has the internal surface of the guide surface defined by an annularly-oblique abutment surface thereon so that, when the water plug is pushed by the reflux of strong water pressure, the abutment surface can gradually close onto the abutment portion and synchronically work with the reflux of the water pressure to form a sufficient force compressing the spring element thereby; when the water pressure at the outlet end is lower than the elasticity of the spring element, the movable element will be bounced by the spring element to slide along the bore towards the outlet end thereof.
