[0002] Faucet is the popular name of water valve, is used for controlling the size switch of water flow, has the effect of water saving. The working principle of faucet is usually based on the principle of pressure difference. When operating the control rod, the control rod will adjust the opening and closing degree of the water valve, thereby controlling the size of water flow. At the same time, the throttling device can limit the amount of water flow by changing the shape and size of the passage, thereby realizing the water saving effect.

[0003] At present, more faucets adopt integrated casting forming setting, but the casting process is complex, and the mold cost is high. Therefore, part of the split type faucet appears in the market, which is produced separately (such as valve body, handle is separately cast or stamped), and then assembled by welding, the process is relatively simple, the cost is lower, and it is suitable for mass production.
