The present invention relates to a structure of a ceramic balancing control valve of a faucet, especially for a ceramic balancing control valve to prevent excessive pressure difference.
To avoid the instability of water pressure caused by cold or hot running water, which results in fluctuation of the water temperature, therefore a balancing valve is installed in the ceramic control valve of the faucet. The structure is composed of a fixed valve pipe, with a movable spool in it. There are a few sets of gaskets within the body of the fixed valve pipe. Each side of the pipe body engraves a conduction gap. Each side has a concave groove compartment; the concave groove compartments are separated by a partition. A conduction gap is installed at each of the interior part of the concave groove compartment, so that the movable spool can be adjusted when there is a change of cold and hot water pressure, thereby changing the corresponding conduction gap of the movable spool and the fixed valve pipe to achieve automatic balancing of hot and cold water temperature; However, when the balancing valve is in use, the strong currents will run directly from the corresponding conduction gap of the movable spool and the fixed valve pipe into the ceramic control valve, and a great pressure difference will be formed between the ceramic control valve and the balancing valve. The pressure will cause the rapid displacement of the movable spool and produce a great deal of noise. When the movable spool is often in a highly active collision under the displacement, it is also likely to cause damages to those counterparts.
Therefore, there remains a need for a new and improved balancing control valve of a faucet to overcome the problems stated above.
When the conventional balancing valve is in use, the strong currents will run directly from the corresponding conduction gap of the movable spool and the fixed valve pipe into the ceramic control valve, and a great pressure difference will be formed between the ceramic control valve and the balancing valve. This is the problem that needs to be solved.
The present invention provides a structure of the faucet's ceramic balancing control valve, which includes a fixed valve pipe, a movable spool, two flow covers and two caps, which the fixed valve pipe has a consistently axial through hole. Each side of the pipe body engraves a conduction gap by formation with the through hole. A ring groove is set at the exterior of the conduction gap on the fixed valve pipe, and a sealing ring is provided on the ring groove. The movable spool is located inside the through hole of the fixed valve pipe. Each side has a concave groove compartment; the concave groove compartments are separated by a partition, and each side has a grooving tool that corresponds to the conduction gap in the second concave groove compartment. The two flow covers are facing the same setting, on the inside has a flow channel, in order to cover the fixed valve pipe of the balancing valves. On the upper and lower part, each has a flow channel, and the flow tube corresponds to a conduction gap of the fixed valve pipe. The outside of the two caps each provided with at least one circulation hole on the top of the caps combined with the flow tube, so that the inflow of water can change the outflow from circulation hole through the caps. Therefore, a structure of the faucet's ceramic balancing control valve can be obtained.
Comparing with prior arts, the present invention is advantageous because (i) the present invention provides a structure of the faucet's ceramic balancing control valve. When the cold and hot water is imported from the flow covers, it will first be blocked by the caps. After a water room is accumulated inside the flow covers, the reduction of water will flow from the circulation hole. It is served to prevent a large water flow from directly being poured into the ceramic control valve, which will form a large pressure difference between the ceramic control valve and the balancing valve; and (ii) the present invention provides a structure of the faucet's ceramic balancing control valve, which utilizes the set up of caps to reduce hot and cold water flow from the circulation hole. It can prevent the forming of excessive pressure between the ceramic control valve and the balancing valve. Therefore when it is in use, it does not generate great noise brought by the rapid displacement of the movable spool, it can also prevent excessive collision of the movable spool that accelerates the damage to the counterparts.

In another embodiment, the top and bottom part of the flow tube (32) are set with a gasket (33) at the top and bottom surface of the flow covers (30).
Comparing with prior arts, the present invention is advantageous because (i) when the cold and hot water is imported from the flow covers (30), it will first be blocked by the caps (40). After a water room is accumulated inside the flow covers (30), the reduction of water will flow from the circulation hole (41). It is served to prevent a large water flow from directly being poured into the ceramic control valve (50), which will form a large pressure difference between the ceramic control valve (50) and the balancing valve; and (ii) the present invention utilizes the set up of caps (40) to reduce hot and cold water flow from the circulation hole (41), which can prevent excessive pressure between the ceramic control valve (50) and the balancing valve. Therefore when it is in use, it does not generate great noise brought by the rapid displacement of the movable spool (20), and it can also prevent excessive collision of the movable spool (20) that accelerates the damage to the counterparts.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
