The invention is described in further detail below with reference to the figures and specific examples.
With reference to fig. 2 and 3, the present invention discloses a valve core ceramic plate set structure capable of precisely adjusting temperature, which includes an upper ceramic plate 3 and a lower ceramic plate 4 matched with the upper ceramic plate 3, wherein a water mixing cavity 43 is sunk on the upper end surface of the lower ceramic plate 4, a cold water inlet 41 and a hot water inlet 42 are symmetrically arranged on the lower ceramic plate 4 at two sides of the water mixing cavity 43, a mixed water outlet 44 is arranged on the water mixing cavity 43, and the mixed water outlet 44 is arranged on the symmetrical center line of the cold water inlet 41 and the hot water inlet 42 and close to one side of the water mixing cavity 43, so that the cold water inlet 41, the hot water inlet 42 and the mixed water outlet 44 are on the same circumference; the meniscus cold water temperature regulating groove 31 and the hot water temperature regulating groove 32 are symmetrically arranged on the lower end surface of the upper ceramic plate 3 in a sinking mode, the cold water temperature regulating groove 31 and the hot water temperature regulating groove 32 are respectively arranged at the cold water inlet 41 and the hot water inlet 42 in a spanning mode, one side, adjacent to the cold water temperature regulating groove 31 and the hot water temperature regulating groove 32, of the cold water temperature regulating groove is arranged in a gradually reducing mode, and the width of a gradually reducing notch is smaller than the caliber of each water inlet.
As shown in fig. 1, the ceramic sheet set of the present invention is implemented in a constant pressure valve, and the constant pressure valve can ensure the pressure and balance of the hot and cold water inlet, so that the temperature adjustment accuracy of the constant pressure valve can be better embodied.
The embodiment of the invention is described by taking a constant pressure valve as an example: the constant pressure valve comprises a valve casing 0, an upper ceramic piece 3 and a lower ceramic piece 4 are assembled in the valve casing 0, a temperature adjusting block 1 is matched on the upper portion of the valve casing 0, a temperature control rod group 2 penetrates through the temperature adjusting block 1 and penetrates into the valve casing 0 to be matched with the upper ceramic piece 3, namely, the temperature control rod group 2 drives the upper ceramic piece 3 to rotate relative to the lower ceramic piece 4 so as to achieve the temperature adjusting function, an upper valve seat 5 is in sealing fit with the lower portion of the lower ceramic piece 4, and the upper valve 5 is matched with the lower valve seat 6 so as to install a balance valve 7.
As shown in fig. 1, a temperature indication mark 11 is arranged on the temperature adjusting block 1 to show the rotation angle of the temperature control rod group 2, wherein a scale mark is arranged at every 6 degrees, and the temperature of the temperature control rod group 2 is adjusted to about 2 degrees after rotating every 6 degrees within the temperature range of 34-49 degrees. When the temperature control rod group 2 rotates 6 degrees every time, the linkage upper ceramic plate 3 also rotates 6 degrees, and the cold water temperature adjusting hole 31 is overlapped with the cold water inlet 41 to define the water inlet area of the cold water; the hot water temperature control hole 32 overlaps the hot water inlet 42 to define a hot water inlet area. The cold water and the hot water are in a certain proportion, and the derivation formula of the proportion is as follows:
theoretical cold water temperature: 10 deg.C
Theoretical hot water temperature: 66 deg.C
From the law of conservation of endothermic heat release: CMh (66-T) ═ CMc (T-10)
To obtain: t ═ 66+10R)/(R +1)
Wherein: r is the ratio of cold water to hot water (R is SC/SH); m is the weight of water; SC is the hot water area; SH is the cold water area; t is the mixing temperature.
Thus, the mixed water with the set temperature is uniformly mixed in the mixing chamber 43, and the mixed water is discharged through the mixed water outlet hole 44, so as to achieve the effect of accurately adjusting the temperature. In a word, the temperature control rod group 2 drives the upper ceramic plate 3 to rotate, so that the cold water temperature adjusting tank 31 and the hot water temperature adjusting tank 32 of the upper ceramic plate 3 are overlapped with the cold water inlet 41 and the hot water inlet 42 to form an external water outlet in an open state.
The specific working state is shown in fig. 4A to 4F in combination with fig. 5 to 7:
1. when the cold water temperature adjusting tank 31 and the hot water temperature adjusting tank 32 of the upper ceramic plate 3 form an angle of 90 degrees with the cold water inlet 41 and the hot water inlet 42 of the lower ceramic plate 4, the constant pressure valve is in a closed state.
2. When the upper ceramic plate 3 rotates by 28 degrees, only cold water is discharged, namely hot water is fed, and the temperature is 10 ℃.
3. When the upper ceramic plate 3 rotates by 58 degrees, the ratio of the water inlet area of hot water to the water inlet area of cold water is 0.598, and the mixed water temperature is 34 ℃.
4. When the upper ceramic plate 3 rotates by 82 degrees, the ratio of the water inlet area of hot water to the water inlet area of cold water is 1, and the mixed water temperature is 38 ℃.
5. When the upper ceramic plate 3 rotates by 118 degrees, the ratio of the hot water to the cold water inlet area is 1.462, and the mixed water temperature is 49 ℃.
6. When the upper ceramic plate 3 rotates 150 degrees, only hot water is discharged at a limit angle, and the temperature is 66 ℃.
The following is a temperature regulation data analysis meter of the constant pressure valve
