Swivel-type precision ceramics control balance valve
A precision ceramics control balance valve includes a valve housing, a rotary base mounted in the valve housing, a valve lever mounted on the rotary base and protruding upward from the valve housing, a movable valve plate mounted in the valve housing and located under the rotary base, a fixed valve plate mounted in the valve housing and located under the movable valve plate, a valve seat mounted on a lower end of the valve housing to stop the fixed valve plate, the movable valve plate and the rotary base, a temperature limiting device mounted in the valve seat, a pedestal connected with the valve seat, and a balance unit mounted in the pedestal.
1. A control balance valve comprising:
a valve housing;
a rotary base mounted in the valve housing;
a valve lever mounted on the rotary base and protruding upward from the valve housing;
a movable valve plate mounted in the valve housing and located under the rotary base;
a fixed valve plate mounted in the valve housing and located under the movable valve plate;
a valve seat mounted on a lower end of the valve housing to stop the fixed valve plate, the movable valve plate and the rotary base; and
a pedestal connected with the valve seat;
wherein the rotary base is locked onto the movable valve plate, and the valve lever drives the rotary base which drives the movable valve plate to rotate relative to the fixed valve plate; the movable valve plate is provided with a first cold water hole and a first hot water hole which are arranged diagonally; the fixed valve plate has a center provided with a second cold water hole and a second hot water hole; the valve seat includes an upper section and a lower section combined together; and the lower section of the valve seat and the pedestal are formed integrally,
wherein the first cold water hole has a first extension to enlarge an extent of the first cold water hole, and the first hot water hole has a second extension to enlarge an extent of the first hot water hole; the first cold water hole and the first extension misalign with a first cold water channel and a first temperature regulating hole of the fixed valve plate, while the first hot water hole and the second extension misalign with the second hot water hole and a first hot water channel of the fixed valve plate under a state that the valve lever is not operated, so that the cold water and the hot water are stopped by the movable valve plate and cannot flow outward from the faucet through the control balance valve.
2. A control balance valve comprising:

a rotary base mounted in the valve housing;
a valve lever mounted on the rotary base and protruding upward from the valve housing;
a movable valve plate mounted in the valve housing and located under the rotary base;
a fixed valve plate mounted in the valve housing and located under the movable valve plate;
a valve seat mounted on a lower end of the valve housing to stop the fixed valve plate, the movable valve plate and the rotary base; and a pedestal connected with the valve seat;
wherein the rotary base is locked onto the movable valve plate, and the valve lever drives the rotary base which drives the movable valve plate to rotate relative to the fixed valve plate; the movable valve plate is provided with a first cold water hole and a first hot water hole which are arranged diagonally; the fixed valve plate has a center provided with a second cold water hole and a second hot water hole; the valve seat includes an upper section and a lower section combined together; and the lower section of the valve seat and the pedestal are formed independently and are assembled together,
wherein the first cold water hole has a first extension to enlarge an extent of the first cold water hole, and the first hot water hole has a second extension to enlarge an extent of the first hot water hole; the first cold water hole and the first extension misalign with a first cold water channel and a first temperature regulating hole of the fixed valve plate, while the first hot water hole and the second extension misalign with the second hot water hole and a first hot water channel of the fixed valve plate under a state that the valve lever is not operated, so that the cold water and the hot water are stopped by the movable valve plate and cannot flow outward from the faucet through the control balance valve.
