Embodiment
Hereafter by the drawings and specific embodiments, the utility model is described further.
With reference to figure 1-3, a kind of single coaxial temperature controlled valve core, comprising:
One valve body 1, its have from top to bottom set gradually blend the mouth of a river 13, cold water inlet 11, water inlet of hot water 12;
One thermosensitive element 2 with temperature-sensitive end and telescopic end, described thermosensitive element 2 by guiding device 21 axial limiting, described temperature-sensitive end near described in blend the mouth of a river 13, blend the water-exit temperature information at the mouth of a river 13 for perception, and pass to described telescopic end;
One is arranged and the piston apparatus 22 that can slide at described valve inner with described thermosensitive element 2 interlock, described water inlet of hot water 12 place is provided with the first seal ring 121, when described piston apparatus slides to extreme lower position 22 times, described piston apparatus 22 and the first seal ring 121 are fitted, by completely closed for described water inlet of hot water 12.
Described piston apparatus 22 is located in described valve body 1, and slides in the region between cold water inlet 11 and water inlet of hot water 12; When the perception of described thermosensitive element 2 blends the temperature drift at the mouth of a river 13, described telescopic end extends, and described piston apparatus 22 slides towards the direction of hot water outlet 12, thus the flow of hot water outlet 12 is diminished; When described thermosensitive element sense 2 knows that the temperature blending the mouth of a river 13 is on the low side, described telescopic end shortens, and described piston apparatus 22 slides towards the direction of cold water water outlet, thus the flow of cold water water outlet is diminished.
Therefore, when cold water inlet 11 place does not have cold water to flow into, it is higher that the temperature-sensitive end of described thermosensitive element 2 experiences the current temperature blending the mouth of a river, described telescopic end is heated and is stretched to the longest position, thus drive described piston apparatus 22 to slide down to extreme lower position, described piston apparatus 22 and the first seal ring 121 are fitted, by completely closed for described water inlet of hot water 12.Therefore, water inlet of hot water 12 can be closed completely when cold water inlet 11 does not have cold water to flow into, thus ensure that user can not be scalded by overheated current.
In the present embodiment, also comprise a guide rod 3 and screw rod 4; Described guide rod 3 is installed in described valve body 1, and its one end is connected by transmission thread 31 with described screw rod 4, and the other end of described screw rod 3 is exposed to outside the top of described valve body 1; Rotating described screw rod 4 drives described guide rod 3 to slide up and down, when described guide rod 3 slides down to extreme lower position, described in blend the mouth of a river 13 and be closed.
The second seal ring 32 is provided with between described guide rod 3 and described valve body 1 inwall.Thus by the transmission thread 31 of guide rod 3 with blend the mouth of a river 13 and keep apart, transmission thread 31 can remain dry.Such transmission thread 31 after long-term use, also can not affect rotation feel because of generation incrustation scale, transmission thread 31 can normally be used for a long time.
Described screw rod 4 is provided with the through hole 41 of a connection outside air and valve body 1 inside, makes the pressure inside and outside valve body 1 consistent, can not affect the rotation of transmission thread, further ensuring the feel of transmission thread because of producing air pressure negative pressure.
Described mixing water outlet 13 mouthfuls of places are provided with the 3rd seal ring 131, and when described guide rod 3 slides down to extreme lower position, described guide rod 3 and the 3rd seal ring 131 are fitted, and are closed completely at the described mouth of a river 13 that blends.
Described guiding device 21 is provided with relief hole 211.Reduce the active force of hydraulic pressure to thermosensitive element 2 by relief hole 211, improve the stability of thermosensitive element 2.
Described cold water inlet 11 and water inlet of hot water 12 are respectively equipped with filter screen.The impurity in water can be filtered out, improve the clean outlet degree blending the mouth of a river 13.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
