Coaxial three-control constant temperature valve element and faucet thereof

Abstract

The invention provides a coaxial three-control constant temperature valve element. The coaxial three-control constant temperature valve element comprises a movable ceramic chip, a fixed ceramic chip,a valve element sleeve and a valve sleeve base; the valve sleeve base is arranged on the valve element sleeve, a hot water inlet, a mixed water outlet and a cold water inlet are formed in the bottom of the valve sleeve base, the top end of the movable ceramic chip is connected with a flow adjusting sleeve, the top of the valve element sleeve is fixedly connected with a temperature adjusting sleeve, the top end of the temperature adjusting sleeve is provided with a temperature control valve rod for controlling the water temperature, the periphery of the temperature adjusting sleeve is rotatablysleeved with a flow valve rod which controls the flow adjusting sleeve to rotate and drives the movable ceramic chip to rotate relative to the fixed ceramic chip so as to control cold and hot water on-off states and cold and hot water flow, a thermosensitive element is arranged in a mixed water runner of the valve sleeve base, a mixed water cavity is formed between the flow adjusting sleeve and the thermosensitive element, an adjuster fixed to the thermosensitive element in a sleeving manner is arranged in the mixed water cavity, and the thermosensitive element drives the adjuster to move upand down to adjust the water inlet amount of the cold and hot water so as to control mixed water with the constant temperature in the mixed water runner to flow out. The invention further provides a water faucet with the coaxial three-control constant temperature valve element.

Description

【Technical field】 [0001] The invention relates to plumbing equipment technology, in particular to a coaxial three-control thermostatic valve core and a faucet thereof. 【Background technique】 [0002] With the improvement of people's living standards, most of the faucets for domestic water use cold and hot water faucets. When using ordinary faucets, due to changes in the adjusted water temperature due to changes in the cold and hot water supply pressure, it is easy to cause the water temperature of the mixed water supplied. There are sudden fluctuations in hot and cold, especially when bathing, the user will feel cold immediately, which will cause the body to feel uncomfortable, and cause a waste of water resources. [0003] Constant temperature and constant pressure faucets are promoted by people due to water saving and environmental protection, and are more and more widely used in bathing water supply systems in various occasions. The advantage of constant temperature and c...

Problems solved by technology

[0004] However, most of the faucets on the market currently use side outlets, resulting in complex structures, high costs, cumbersome processing techniques, difficult processing, and generally high prices, making it difficult to promote and popularize applications; although it can balance the changes in water supply pressure, the response is not enough. Sensitive, there is a certain delay, so the outlet water temperature is not constant enough
