Thermostatic valve core and self-heating metal thermostatic tap made by using same

Abstract

The invention belongs to the technical field of thermostatic heating devices and relates to a thermostatic valve core and a self-heating metal thermostatic tap made by using the same. A cold water region is communicated with a cold water inlet; the cold water region and a heating water region are communicated by a water inlet valve; the heating water region is internally provided with an electric heater, the heating temperature of the electric heater is controlled by a water temperature automatic controller; the lower parts of the cold water region and the heating water region are respectively communicated with the inner cavity of a cold and hot water mixed region through two arc openings arranged on the cylindrical surface of the thermostatic valve core; the seal groove at the outer cylindrical surface of the thermostatic valve core is provided with an annular sealing ring which is sealed relative to a shell; the other end of a valve rod of the thermostatic valve core is externally connected to a temperature controlling hand wheel; a water outlet valve is arranged between the cold and hot water mixed region and a water discharging region; and an water outlet is arranged on the water discharging region. The invention has the advantages of convenient use, energy saving and water saving, reasonable structural design, thermostatic water discharging, low cost, long service life and high precision to control temperature, and can save water resources.

Description

technical field [0001] The invention belongs to the technical field of constant temperature heating devices, in particular to a constant temperature valve core and a self-heating metal constant temperature water tap made of the same. Background technique [0002] At present, the hot and cold mixed water outlet constant temperature faucets on the market usually do not directly heat the water temperature in the faucet. The hot water in the faucet is generally provided by solar hot water tanks or electric / gas water heaters or boilers. One: solar hot water The water in the tank uses the sun as the heating energy source. If it is rainy season or there are continuous cloudy days, the water in the solar hot water tank cannot receive solar energy, so it cannot provide heat for the water in the solar water tank. Two: water heater The water supply needs to be heated by electric heating pipes or gas combustion to heat the water in the larger water tank, but it takes a while for the wat...

[0002] At present, the hot and cold mixed water outlet constant temperature faucets on the market usually do not directly heat the water temperature in the faucet. The hot water in the faucet is generally provided by solar hot water tanks or electric / gas water heaters or boilers. One: solar hot water The water in the tank uses the sun as the heating energy source. If it is rainy season or there are continuous cloudy days, the water in the solar hot water tank cannot receive solar energy, so it cannot provide heat for the water in the solar water tank. Two: water heater The water supply needs to be heated by electric heating pipes or gas combustion to heat the water in the larger water tank, but it takes a while for the water heater to heat the water, which brings inconvenience to customers; there is also a constant temperature faucet that mixes hot and cold water. During use, due to the change of water supply pressure or the heating of hot water temperature, it is difficult to balance the cold and hot water. Generally, it is necessary to manually test the water temperature and adjust the temperature. When manually testing the water temperature and adjustment, occasionally you will burn if you do not pay attention to the water temperature. , There is also a waste of water resources, which brings much inconvenience to people's lives;

[0003] There are thermostatic valve cores in the hot and cold mixed water outlet constant temperature faucets in the existing market, but due to the unreasonable design of the thermostatic valve cores, the main temperature sensing materials inside generally use waxy temperature bulbs, and the waxy materials are heated and expanded by heat conduction to push the column This type of thermostatic spool has some disadvantages: high cost, short life, low accuracy of temperature control
