Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a faucet control valve and, more particularly, to a faucet control valve for simplifying assembly, to thereby effectively provide the purpose of conveniently assembling, simplifying the process and reducing material costs.

2. Description of Related Art

The structure of a control valve 12 of a general faucet (as shown in FIG. 1), which is consist of an upper case 121, a lever 122, a holder 123, an upper valve sheet 124, a lower valve sheet 125 and a base 126, is used for installing inside the faucet body 11 (as shown in FIG. 2) for controlling water flowing in and out. The assembly inside the faucet is mainly installing the control valve 12 inside the body 11, the lever 122 on the top of the control valve 12 is connected to a handle 13 for operating the control of water flowing in and out. The bottom of the control valve 12 is attached on a valve body seat 14. At least a water inlet hole 142, a water outlet hole 145 and at least a positioning hole 144 are set on the top side of the valve body seat 14. A lateral hole 146 is set on the middle section of the valve body seat 15 and connected to the water outlet hole 145, and an outlet 143 is set on the outlet end of the lateral hole 146. An internal thread section 147 is set on the lower end of the water inlet hole 142 of the valve body seat 14 for an inlet tube 15 screwing on. Basically, there are no problems in using the abovementioned structure, but the production of the valve body seat 14 is truly troubled the industry. Since the volume of the valve body seat 14 is large, it consumes a large amount of copper and is produced through complicated processes, such as cutting, tapping and drilling. In the process, if there is any error occurred in one of the holes, the valve body seat 14 becomes a waste. In Recent years, especially under the condition of rising raw materials price, defective products produced in manufacturing process have become a heavy burden on manufacturing costs. The widely used control valve 12 structure cannot be connected to the inlet tube 15 if not use the valve body seat 14 for supporting the control valve 12, the industry is deeply troubled by rising material costs and complicated machining process.
