During work, cold water flows into from cooling water inlet 81, and hot water flows into from hot water inlet 82, after cold water and hot water mixing, from
Mixed water exports 71 flow out, as shown in Figure 4.When mixing water water temperature is higher than steady temperature, sensing rod for temperature 31 is heated to be made in sensing rod for temperature
Thermo-sensitive material expansion, promote drive link 32 move upwards, because drive link 32 is conditioned cap in the presence of second spring 10
21 prop up, therefore under reaction force acts, sensing rod for temperature 31 moves down with piston 4 and compresses the first spring 5, makes the water inlet of hot water
Gap (gap i.e. between the hot water end 43 of piston 4 and valve seat 7) reduces, and cold water enters water space (the i.e. cold water end 42 of piston 4
Gap between the ring-shaped step) increase, so that the water temperature drop of mixing water is to steady temperature.When mixing water water temperature is low
When steady temperature, the thermo-sensitive material in sensing rod for temperature 31 shrinks, and under the restoring force effect of the first spring 5, piston 4 moves up, and makes
Hot water enters water space increase, and cold water enters water space reduction, so that the water temperature of mixing water rises to steady temperature.Working
During, even if the water space that enters of hot water is reduced to minimum, when even zero, still some hot water can be by piston 4
Overfall 41 flow into cage assembly in, it is ensured that hot water remains the flow not less than 2.5L/min, avoid gas heater because
Flow is small to cause the problem of lighting a fire of stopping working repeatedly, so as to avoid shower faucet water outlet sometimes hot and sometimes cold.
When user needs high-temperature water, adjusting screw rod 1 is rotated, it is passed sequentially through adjusting set 2, adjusting set 21, temperature-sensitive and moves
Dynamic component 3 moves up with piston 4, makes the water space that enters of hot water increase to maximum, and the water space that enters of cold water is then reduced to zero, because
This, the as high-temperature water flowed out from mixed water exports 71.When user needs water at low temperature, adjusting screw rod is rotated, it is led to successively
Overregulate set 2, adjustment cap 21, temperature-sensitive moving assembly 3 to move down with piston 4, make the water space reduction of entering of hot water (now, still have
A part of hot water can be flowed into cage assembly by the overfall 41 on piston 4), the water space that enters of cold water then increases to maximum,
Therefore, the as water at low temperature flowed out from mixed water exports 71.
A kind of constant temperature valve core of carry potential overflow mouth of the present utility model, except can apply to shower faucet, can also be applied
In tap for washbasin or Kitchen tap etc..
A kind of shower faucet of the present utility model, the constant temperature valve core for the carry potential overflow mouth being provided with described in above-described embodiment.
