antifreeze faucet

Abstract

This application relates to an antifreeze water faucet, which includes a faucet body, a water pipe, a valve body, and an opening and closing handle. There is a sealing head, and a connecting rod is installed in the water pipe. One end of the connecting rod is hinged with a lifting rod. The length, the outer wall of the connecting rod near the faucet body is provided with an inner sealing ring, and the end of the water pipe near the faucet body is provided with an outer sealing ring. When the opening and closing handle is fully opened, the inner sealing ring is located above the outer sealing ring and maintains a gap. When the opening and closing handle is closed , the inner sealing ring moves down past the outer sealing ring to the bottom of the outer sealing ring and maintains a gap. There is a stopper on the faucet body, and the stopper restricts the opening and closing handle to maintain a half-open state. At this time, the outer sealing ring and the inner sealing ring conflict and close The faucet body, this application has the effect of reducing the waste of water resources.

Description

technical field [0001] The present application relates to the field of faucet manufacturing, in particular to an antifreeze faucet. Background technique [0002] Tap water is an indispensable living resource in daily life. However, in the cold winter, especially the water pipes and faucets that are installed outdoors and located above the soil layer are easily affected by low temperature, which makes the residual water in the interior freeze into ice, and the water freezes. After the volume becomes larger, it will not only affect the flow of tap water in the next use, but also need to be thawed before use, and may also cause the water pipe or faucet to directly burst and crack. [0003] As a result, an antifreeze faucet is currently provided that can drain the water from the faucet and the pipeline on the soil layer after being closed. It is located in the soil layer, and a drainage hole is also arranged. After closing the water inlet, the drainage hole is opened to dischar...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the faucet can achieve the function of drainage and antifreeze when the ambient temperature is below the freezing point, but there is still a long period of time in a year when the ambient temperature is above the freezing point. A large amount of water resources are wasted at one time, which does not meet the water saving requirements
