Description

A rotating part of a tap water antifreeze faucet

technical field

The utility model belongs to the technical field of faucets, in particular to a rotating component of a tap water antifreeze.

Background technique

The water outlet of the water pipe is generally exposed above the ground. When winter comes, the pipe at the water outlet is easy to freeze and freeze, which causes inconvenience in use. The existing antifreeze valve mainly uses a built-in temperature sensor, which can accurately sense the water temperature and can be opened and closed without any power supply. As the ambient temperature decreases, the antifreeze valve opens when the water temperature is close to the freezing point, and the low-temperature water in the system is quickly discharged. When the water temperature rises to the set value, the pressure antifreeze valve is closed and the drainage is stopped. This process will be cycled as needed to keep the amount of water drained from the system to a minimum while preventing freezing. This antifreeze tap for tap water needs to be drained to achieve antifreeze, resulting in a waste of water resources. Secondly, there is another way to use electric heating to heat the external water pipes to prevent freezing, which causes energy waste.

There is also a freeze-proof faucet. This type of faucet features a shut-off valve located at one end of an extension tube or sleeve that is located in the wall or in the warmer interior area of the building that is formed by the wall. The shut-off valve is operated by an extension rod connected to an external handle. The antifreeze feature of the cock is caused by the antifreeze valve, which shuts off the water flow at one point in the wall or in the building, and the remaining water in the extension pipe flows outward by gravity and is discharged through the antifreeze valve outlet.
