Abstract

A water valve may include a valve shell, and a rotating base is installed in the valve shell. A lower end of the rotating base is sequentially connected to a driving valve piece and a fixed valve piece, and the driving valve piece and the fixed valve piece are installed in the valve shell. A bottom portion of the driving valve piece comprises a concave portion to form a mixing chamber, and the mixing chamber has a first mixing space and a second mixing space, and the diameter of the first mixing space is larger than the second mixing space so as to increase the coverage of the mixing chamber. Each of two sides of the second mixing space comprises a pressure relief slot.

Claims

1. A water valve comprising a valve shell, and a rotating base installed in the valve shell;

a lower end of the rotating base sequentially connected to a driving valve piece and a fixed valve piece, and the driving valve piece and the fixed valve piece installed in the valve shell;

a center of a top portion of the rotating base comprising a valve rod upwardly protruding out of the valve shell;

the rotating base configured to engage with the driving valve piece, and through operating the valve rod, the rotating base, which is driven by the valve rod, adapted to drive and have synchronous rotation with the driving valve piece so as to change the relative positions between the driving valve piece and the fixed valve piece and to control on/off operation of a faucet, ratio of hot water and cold water, and the amount of water flow;

a base coupled with and blocking a bottom portion of the valve shell to secure the fixed valve piece, the driving valve piece, and the rotating base in the valve shell;

the base comprising a water inlet chamber, and a balanced valve installed therein;

wherein the valve shell comprises a housing, and an upper portion of the housing is connected to a ring portion which has a first opening at a central portion thereof, and the diameter of the ring portion is smaller than the housing;

the rotating base, the driving valve piece, and the fixed valve piece are positioned in the housing of the valve shell, and the valve rod is configured to upwardly protrude out of the valve shell through the first opening;

wherein a bottom portion of the driving valve piece comprises a concave portion to form a mixing chamber, and the mixing chamber has a first mixing space and a second mixing space, and the diameter of the first mixing space is larger than the second mixing space so as to increase the coverage of the mixing chamber;

each of two sides of the second mixing space comprises a pressure relief slot;

when the driving valve piece is rotated in one direction or the other direction, the pressure relief slot is communicated with a cold water hole or a hot water hole of the fixed valve piece so as to relieve pressure in the balanced valve which is installed in the base;

wherein the fixed valve piece comprises the arc-shaped cold water hole and the arc-shaped hot water hole which axially penetrate through the fixed valve piece respectively and are formed symmetrically;

a first water outlet hole and a second water outlet hole respectively and vertically penetrate through the fixed valve piece between the cold water hole and the hot water hole, and the first water outlet hole and the second water outlet hole are spaced apart toward two lateral sides of the cold water hole and the hot water hole;

wherein the base has a water inlet chamber and two water outlet chambers, which are formed separately in the base;

a first cold water inlet and a first hot water inlet, which are formed separately, are respectively connected at an upper end of the water inlet chamber and vertically penetrate the base;

the two water outlet chambers, which are respectively formed at two sides of the water inlet chamber, are respectively connected to a first drain and a second drain at upper ends thereof, and the first drain and the second drain respectively and vertically penetrate through the base;

the rotating base, the driving valve piece, and the fixed valve piece in the housing are stacked in sequence, and the base is connected to the valve shell so as to load the fixed valve piece, the driving valve piece, and the rotating base;

the fixed valve piece is engaged with a top surface of the base, and the first cold water inlet, the first hot water inlet, the first drain, and the second drain of the base are respectively aligned with the cold water hole, the hot water hole, the first water outlet hole, and the second water outlet hole of the fixed valve piece;

before the valve rod is operated, the mixing chamber of the driving valve piece is misaligned with the hot water hole, the first water outlet hole, and the second water outlet hole of the fixed valve piece such that cold water and hot water are blocked by the driving valve piece and not flow out from the water valve; and

wherein the balanced valve comprises two halves of cases, and the two cases are configured to fit together to accommodate a fixed valve pipe and a valve core therebetween;

each of the cases has a horizontal through hole formed at a lateral surface thereof, and the two through holes are faced to each other;

each of the cases comprises a water passage penetrating from a top surface to a bottom surface of the case and communicated with the through hole;

the two through holes are adapted to enable the fixed valve pipe and the valve core to be accommodated in the cases when the two halves of cases are fitted together;

the balanced valve is positioned in the water inlet chamber of the base to secure the fixed valve pipe in the cases, and the two water passages of the two cases are respectively aligned with the first cold water inlet and the first hot water inlet of the base;

the fixed valve pipe has an O-ring disposed thereon, and each of two lateral sides of the fixed valve pipe comprises a first recess section;

each of two ends of the valve core is concaved inwardly to form a valve room, and the two valve rooms are separated by a partition;

each of the two valve rooms has a second recess section formed on a surface thereof to enable the valve core to move in the fixed valve pipe along with the water pressure occurred by cold water inflow and hot water inflow, so as to change the relative position between the first recess section and the second recess section, thereby automatically balancing the water pressure in the water valve.

2. The water valve of claim 1, wherein the water valve comprises a temperature control unit which is adapted to limit the rotating angle of the valve rod.

3. The water valve of claim 1, wherein the water valve is positioned in a valve chamber of a shunt valve for use, and the shunt valve comprises a second cold water inlet, a second hot water inlet, a first water channel, and a second water channel respectively penetrating through a bottom portion of the valve chamber;

the second cold water inlet and the second hot water inlet are respectively connected to cold water source and hot water source, and the first water channel and the second water channel are respectively connected to two water equipments, such that through operating the water valve, cold water, hot water, or warm water mixed from cold water and hot water is configured to flow through one of the water equipments.

4. The water valve of claim 1, wherein a detachable adapter is connected to the valve rod, and through the adapter, the valve rod is configured to connect to different types of handles.

5. The water valve of claim 1, wherein the pressure relief slot is formed in a triangle shape.
