Cold and hot water tap

Abstract

The invention discloses a cold and hot water tap which comprises a cold and hot water tap body; a cold water channel, a hot water channel, a water outlet channel and valves for adjusting the fluxes of the cold water and the hot water are arranged on the cold and hot water tap body; and the cold water channel and the hot water channel are respectively provided with sub channels between the valves and the water outlet channel; and second valves are respectively arranged on the sub channels. When the valve of only one water inlet channel is opened, a secondary valve at the same side can be opened so as to avoid the resistance to the water flow from bevel wheels. When the valves of the cold water inlet channel and the hot water inlet channel are both opened, the second valves on the sub channels can be closed, so that when hemp threads or raw material tapes or other fibers enter the cold and hot water channels, the hemp threads or raw material tapes or other fibers cannot entangle the bevel wheels, so flexible rotation of the bevel wheels is guaranteed. When cold water and hot water respectively flow from the channels in which the bevel wheels are arranged, the bevel wheel in the channel with bigger water pressure rotates initiatively and the bevel wheel in the channel with smaller water pressure is driven to rotate, so the pressure difference between the cold water and the hot water can be effectively adjusted.

Description

[0001] technical field [0002] The invention relates to a cold and hot water faucet. [0003] Background technique [0004] With the improvement of people's living standards, most of the faucets for domestic water use hot and cold water faucets. Generally speaking, for example, the water outlet pressure of the solar water heater comes from the height difference between the water tank and the water outlet of the solar water heater, so that the pressure of cold water and hot water is different. Even if the water temperature has been adjusted when taking a bath, it will also affect the adjusted water temperature when other people open other faucets on the same pipeline, although some cold and hot water faucets have been technically improved, as the patent number is: 201110191286.2 A kind of cold and hot water faucet , the cold water inlet channel and the hot water inlet channel are respectively integrally provided with an impeller chamber, the impeller chamber is provided wi...

[0004] With the improvement of people's living standards, most of the faucets for domestic water use hot and cold water faucets. Generally speaking, for example, the water outlet pressure of the solar water heater comes from the height difference between the water tank and the water outlet of the solar water heater, so that the pressure of cold water and hot water is different. Even if the water temperature has been adjusted when taking a bath, it will also affect the adjusted water temperature when other people open other faucets on the same pipeline, although some cold and hot water faucets have been technically improved, as the patent number is: 201110191286.2 A kind of cold and hot water faucet , the cold water inlet channel and the hot water inlet channel are respectively integrally provided with an impeller chamber, the impeller chamber is provided with an impeller, and the impeller arranged in the impeller chamber of the cold water inlet channel is arranged on the An impeller shaft and a shaft sleeve are arranged between the impellers in the impeller chamber of the hot water inlet channel, and the impellers are respectively axially connected and fixed to the two ends of the impeller shaft. When the channel of the impeller flows through, it will drive the two coaxial impellers to rotate synchronously. Although this method can effectively adjust the water pressure difference, when only one of the cold water or hot water flows through to drive the impeller to rotate, the other is not opened. The water on the channel will generate pressure between the impeller and the valve, which will cause great resistance to the impeller, resulting in the slow rotation of the impeller on the open water inlet channel, so that the water flow will be greatly reduced
