Abstract

A branch water supply device for a water supply pipe controls the supply of water. A connecting pipe has a pipe body, with pipe inlet and outlet formed at opposite ends. A first valve pipe has a first pipe body, with first inlet and outlet formed on both portions. The first valve pipe is connected to the connecting pipe such that the first inlet communicates with the inside of the pipe body. A second valve pipe has a second pipe body, with a second outlet formed on a portion. The second valve pipe is connected to the first valve pipe and communicates with the inside of the first pipe body. An opening/closing means, provided on a connection between the first and second valve pipes, opens and closes the connection between the first and second valve pipes so that water is selectively supplied to the first and second valve pipes.

Claims

1. A branch water supply device for a water supply pipe comprising:

a connecting pipe having a pipe body, with a pipe inlet and a pipe outlet formed at opposite ends of the pipe body;

at least one first valve pipe having a first pipe body, with a first inlet and a first outlet formed on both portions of the first pipe body, wherein the first valve pipe is connected to the connecting pipe such that the first inlet communicates with an inside of the pipe body;

at least one second valve pipe having a second pipe body, with a second outlet formed on a portion of the second pipe body, wherein the second valve pipe is connected to the first valve pipe and communicates with an inside of the first pipe body; and

at least one opening/closing mechanism provided on a connection between the first and second valve pipes, wherein the opening/closing mechanism opens and closes the connection between the first and second valve pipes so that water is selectively supplied to at least one of the first and second valve pipes,

wherein the opening/closing mechanism includes;

an opening/closing recess provided inside the first valve pipe, with one portion thereof communicating with the first inlet and another portion thereof communicating with the first outlet;

an opening/closing block rotatably received inside the opening/closing recess to open and close at least one of the first outlet of the first valve pipe and the second outlet of the second valve pipe depending on a rotated position thereof;

a fixed cover plate coupled with an entrance side of the opening/closing recess to isolate an inside of the opening/closing recess from outside, wherein the fixed cover plate has position indicators formed at regular intervals in a radial direction; and

an operating knob coupled with the opening/closing block via a connector, which extends through the fixed cover plate, so as to rotate integrally with the opening/closing block, wherein the operating knob is configured to face one of the position indicators, which are in different directions, depending on the rotated position.

2. The branch water supply device according to claim 1, wherein the opening/closing recess has a conical leakage-preventing surface that narrows in a direction toward bottom, the opening/closing block has a conical configuration that narrows in a direction toward bottom so as to be in close contact with the leakage-preventing surface, and a spring is provided between the fixed cover plate and the opening/closing block to support the opening/closing block using a downward elastic force.

3. The branch water supply device according to claim 1, wherein the connector has a fitting protrusion, which protrudes upward through the fixed cover plate and is coupled with the operating knob, and a spring is provided around the fitting protrusion to support the connector using a downward elastic force with respect to the fixed cover plate.

4. The branch water supply device according to claim 3, wherein the fixed cover plate has a protrusion on an upper portion thereof, wherein the protrusion seats the operating knob thereon, has a fitting-hole in an inside thereof, the fitting protrusion of the connector fitted into and coupled with the fitting-hole, and has a support recess in a lower portion thereof in which one end of the spring is positioned.

5. The branch water supply device according to claim 4, wherein the operating knob has a fitting recess into which the fitting protrusion of the connector is fitted, the fitting recess has a bolt-fitting-hole with a fitting step formed thereon, and a knob-fixing bolt is fitted into the fitting recess through the bolt-fitting-hole and coupled with a nut recess formed in the fitting protrusion of the connector.

6. The branch water supply device according to claim 3, wherein the opening/closing recess has a spacer recess below the leakage-preventing surface so that the leakage-preventing surface is spaced apart from a lower end of the opening/closing block.

7. The branch water supply device according to claim 1, wherein the opening/closing block has a first opening/closing hole penetrating a central portion thereof and a second opening/closing hole extending from a portion of the first opening/closing hole in a direction, which intersects the first opening/closing hole, the second opening/closing hole communicating with the first opening/closing hole.

8. The branch water supply device according to claim 1, further comprising a seal for sealing the first outlet of the first valve pipe and the second outlet of the second valve pipe.

9. The branch water supply device according to claim 8, wherein the seal includes:

a holding hook provided on the first valve pipe or the second valve pipe;

a threaded stopper fitted into and coupled with the first outlet of the first valve pipe or the second outlet of the second valve pipe; and

a holding string connecting the holding hook to the stopper.

10. The branch water supply device according to claim 2, wherein the connector has a fitting protrusion, which protrudes upward through the fixed cover plate and is coupled with the operating knob, and a spring is provided around the fitting protrusion to support the connector using a downward elastic force with respect to the fixed cover plate.

11. The branch water supply device according to claim 10, wherein the fixed cover plate has a protrusion on an upper portion thereof, wherein the protrusion seats the operating knob thereon, has a fitting-hole in an inside thereof, the fitting protrusion of the connector fitted into and coupled with the fitting-hole, and has a support recess in a lower portion thereof in which one end of the spring is positioned.

12. The branch water supply device according to claim 11, wherein the operating knob has a fitting recess into which the fitting protrusion of the connector is fitted, the fitting recess has a bolt-fitting-hole with a fitting step formed thereon, and a knob-fixing bolt is fitted into the fitting recess through the bolt-fitting-hole and coupled with a nut recess formed in the fitting protrusion of the connector.

13. The branch water supply device according to claim 10, wherein the opening/closing recess has a spacer recess below the leakage-preventing surface so that the leakage-preventing surface is spaced apart from a lower end of the opening/closing block.

14. The branch water supply device according to claim 2, wherein the opening/closing block has a first opening/closing hole penetrating a central portion thereof and a second opening/closing hole extending from a portion of the first opening/closing hole in a direction, which intersects the first opening/closing hole, the second opening/closing hole communicating with the first opening/closing hole.

15. The branch water supply device according to claim 2, further comprising a seal for sealing the first outlet of the first valve pipe and the second outlet of the second valve pipe.

16. The branch water supply device according to claim 5, wherein the seal includes:

a holding hook provided on the first valve pipe or the second valve pipe;

a threaded stopper fitted into and coupled with the first outlet of the first valve pipe or the second outlet of the second valve pipe; and
