Cold-hot water faucet

Abstract

The invention disclose a cold-hot water faucet which comprises a cold-hot water faucet body, wherein a cold water channel, a hot water channel, a water outlet channel and valves for adjusting the cold water flow and the hot water flow are arranged on the cold-hot water faucet body. The cold-hot water faucet is characterized in that the cold water channel and the hot water channel are respectively provided with one valve, the cold water channel, the hot water channel and the water outlet channel are converged, and the converged parts of the cold and hot water channels and the water outlet channel are respectively provided with an impeller and an impeller shaft. The cold-hot water faucet has the advantages that the pressure difference of the cold water and hot water is effectively adjusted; when other people opens the other water faucet in the same pipeline, only the total flow is reduced, the modulated cold-hot water proportion is basically not changed, and the water temperature is effectively controlled.

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. It can only be adjusted according to the water flow rate of the side with low water pressure. When the flow rate of the side with high water pressure is increased, the side with low water pressure will not be able to discharge water. When the water tap also affects the adjusted water temperature, although some hot and cold water faucets have been improved in technology, as the patent No.: 01276423.

[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. It can only be adjusted according to the water flow rate of the side with low water pressure. When the flow rate of the side with high water pressure is increased, the side with low water pressure will not be able to discharge water. When the water tap also affects the adjusted water temperature, although some hot and cold water faucets have been improved in technology, as the patent No.: 01276423. "T" type diversion tee, this kind of technical improvement, when the pressure difference between cold and hot water is large and the cold water needs to be opened greatly, the water pressure in the cold water pipe and the front part of the "T" diversion tee outlet pipe to the shower When the water pressure in the nozzle is greater than the water pressure in the hot water pipe, not only the hot water cannot come out, but the cold water will flow to the hot water pipe instead, and the water temperature cannot be controlled. Another patent number is: 201110191286.2 A kind of cold and hot water faucet, when the cold water enters The channel and the hot water inlet channel are integrally provided with impeller chambers, and the impeller chambers are provided with impellers, and the impellers arranged in the impeller chambers of the cold water inlet passages are connected with the hot water inlet channels. An impeller shaft and a shaft sleeve are arranged between the impellers in the impeller chamber of the water inlet channel, and the impellers are respectively axially connected and fixed at both ends of the impeller shaft, and the shaft sleeve is integrated with the body of the hot and cold faucet Set, the two ends of the shaft sleeve, the impeller shaft and the shaft sleeve are provided with a bush for sealing and self-lubricating, because the shaft sleeve is set between the cold water inlet channel and the hot water inlet channel, the cold and hot water The passages are sealed with seals and self-lubricating bushings arranged at both ends of the shaft sleeve. Although this method can effectively adjust the water pressure difference, once the bushings are worn, the water pressure on the higher side will be higher when the hot and cold water taps are closed The water will flow to the side with low water pressure, and it is possible that the cold water will flow back to the water tank of the water heater, causing unnecessary losses
