A coaxial three-control thermostatic valve core and its faucet

Abstract

The invention provides a coaxial three-control thermostatic valve core, which includes a moving porcelain piece, a static porcelain piece, a valve core sleeve and a valve sleeve seat. The valve sleeve seat is installed on the valve core sleeve; the bottom of the valve sleeve seat is provided with a hot water inlet Mixed water outlet and cold water inlet; the top of the moving ceramic plate is connected with a flow regulating sleeve, the top of the valve core sleeve is fixedly connected with a temperature regulating sleeve, and the top of the temperature regulating sleeve is installed with a temperature control valve rod to control the water temperature, and the outer periphery of the temperature regulating sleeve is rotated. There is a flow valve stem that controls the rotation of the flow regulating sleeve and drives the moving ceramic plate to rotate relative to the static ceramic plate to control the on-off of hot and cold water and the flow of cold and hot water; a heat-sensitive element is also installed in the mixed water flow channel of the valve sleeve seat, and the flow adjustment A mixing chamber is formed between the sleeve and the heat-sensitive element, and a regulator fixed on the heat-sensitive element is set in the water-mixing chamber. The heat-sensitive element drives the regulator to move up and down to adjust the water intake of cold and hot water to control the mixed water flow. Mixed water with a constant temperature flows out of the channel; the invention also provides a faucet with a coaxial three-control thermostatic valve core.

Description

【Technical field】 [0001] The invention relates to the technology of plumbing equipment, 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 hot and cold water faucets. When using ordinary faucets, because the adjusted water temperature is affected by changes in the water pressure of cold and hot water supply, it is very easy to cause the mixed water temperature. There are sudden fluctuations of hot and cold, especially when taking a bath, the user immediately feels cold, which will cause the body to feel uncomfortable and cause a waste of water resources. [0003] The constant temperature and constant pressure faucet is popularized by people because of water saving and environmental protection, and is more and more widely used in the bathing water supply system in various occasions. The problem of hot and cold outle...

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
