The invention discloses an anti-freezing water supply device and method. The anti-freezing water supply device comprises a sluice valve, a check valve, a faucet and a tee. The sluice valve comprises avalve body and a valve rod. The valve body is installed in a tap water pipeline network below the ground. The valve rod extends out of the ground. The water inlet end of the sluice valve communicateswith the tap water pipeline network. The outlet end of the sluice valve is connected with the first open end of the tee. The faucet is connected with the second open end of the tee through a pipeline. The check valve is connected with the third pipe open end of the tee. When the ground temperature is lower than 0 DEG C, tap water freezes if not flow, an anti-freezing device is started, the faucetis in a long-term open state, and water taking is controlled through opening and closing of the sluice valve. The sluice valve is opened, the check valve is closed under the circumstance of water pressure, and water flows out from the faucet. The sluice valve is closed after water is taken, water pressure in a water pipe is lowered quickly, the check valve is opened, and remaining water in the water pipe is discharged from an outlet. When water is not taken, the ground freezes, no water remains in the pipe, freezing is avoided, and the problem of freezing of tap water in a cold region can besolved.
Description
technical field [0001] The invention discloses an antifreeze water supply device and a method. Background technique [0002] In the Tibetan Plateau and some severe cold areas, winter enters from November to April of the following year, and the lowest temperature in some areas can reach -25°C. The extremely severe cold weather causes faucets to freeze and crack, making them unusable, causing serious harm to local people and animals. Drinking water brings a lot of inconvenience. Contents of the invention [0003] In order to solve the problem in the prior art that the faucet is easy to be frozen, the present invention proposes a new antifreeze water supply device and method, which can solve the problem of faucet frost heaving. [0004] The technical scheme that the present invention adopts is as follows: [0005] An antifreeze water supply device, comprising a gate valve, a check valve, a faucet and a tee; [0006] The gate valve includes a valve body and a valve stem, th...
