[0046] Figure 1 It is an exploded view of the temperature control valve used in the specific embodiment of the present invention. Figure 2 for Figure 1Another exploded view of the temperature regulating valve is shown. Figure 3 for Figure 1 The sectional view of the assembled state of the temperature regulating valve is shown in FIG. Figures 1 to 3 As shown, the temperature regulating valve comprises a valve body 16 , a main shaft 8 , at least two bushings 14 and a first drive mechanism 1 .

[0063] Preferably, the width of the through hole 141 of the bushing 14 is gradually changing along the circumferential direction, and the through holes 141 of two adjacent bushings 14 are arranged in opposite directions. When the main shaft 8 rotates, the water blocking member 6 on one side rotates from the larger diameter end of the through hole 141 to the smaller end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually decreases, and the water blocking member 6 on the other side rotates from the smaller diameter end of the through hole 141 to the larger end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually increases.

If the main shaft 8 rotates outward, the water flow area of ​​the through hole 141 of the left bushing 14 gradually increases as the left water-blocking component 6 rotates away, and when the left water-blocking component 6 rotates to the top of the main shaft 8, the through holes 141 of the left bushing 14 are all opened; at this time, the water flow area of ​​the through hole 141 of the right bushing 14 gradually decreases as the right water-blocking component 6 rotates, and when the right water-blocking component 6 rotates to the bottom of the main shaft 8, the through holes 141 of the right bushing 14 are all closed.

Fig. 22 for Figure 1 Another schematic diagram of the water blocking member of the temperature regulating valve shown in FIG. Fig.21 and Fig. 22 As shown, the water blocking member 6 includes a support column and a water blocking portion.

[0088] In order to improve the sealing performance of the water blocking member 6 to the bushing 14, in addition, preferably, the water blocking member 6 includes a support column and a water blocking portion connected to the support column, the support column is sleeved with a disc spring 7 and inserted into the mounting hole, the water blocking portion overlaps the mounting groove, and the surface of the side facing away from the support column is provided with an arc-shaped protrusion that matches the water inlet.

[0089] The following further introduces the use process of the temperature control valve.

[0090] The water outlet provides mixed water through the water outlet pipe 18, one of the two water inlets is connected to the hot water source through the relative water inlet pipe 3, and the other is connected to the cold water source through the relative water inlet pipe 3; both the hot water source and the cold water source can supply water to the valve cavity, and the valve cavity provides space for mixing hot water and cold water.

[0091] Two water-blocking parts 6 are arranged on the main shaft 8, and a water-blocking part 6 is arranged at each water inlet. The two water-blocking parts 6 are distributed on opposite sides of the axial direction of the main shaft 8. The outer sleeve of each water-blocking part 6 is connected to a bushing 14. The through hole 141 of each bushing 14 is arranged opposite to the water inlet. The width of the through hole 141 of the bushing 14 is gradually changing along the circumferential direction, and the through holes 141 of two adjacent bushings 14 are arranged in opposite directions.

[0092] When one water blocking member 6 completely seals the through hole 141 opposite to it, the other water blocking member 6 completely opens the through hole 141 opposite to it, so that one water inlet is closed due to the sealing effect of the water blocking member 6, and the other water inlet is opened due to the opening effect of the water blocking member 6. The first driving mechanism 1 or the second driving mechanism 10 drives the main shaft 8 to rotate in the valve cavity and the bushing 14, and the main shaft 8 drives the two water blocking members 6 to rotate; so that each water blocking member 6 switches between opening the through hole 141 and closing the through hole 141 to control the opening and closing degree of the corresponding through hole 141, thereby adjusting the water inlet. By controlling the cold water inlet and the hot water inlet, the water outlet of the specified temperature is adjusted.

[0093] When the main shaft 8 rotates, one water-blocking member 6 rotates in the corresponding bushing 14 from the end with a larger diameter of the through hole 141 to the end with a smaller diameter, so that the water flow area of ​​the through hole 141 gradually decreases, and the other water-blocking member 6 rotates in the corresponding bushing 14 from the end with a smaller diameter of the through hole 141 to the end with a larger diameter, so that the water flow area of ​​the through hole 141 gradually increases.

[0094] For example, when the water temperature is low, the water blocking member 6 corresponding to the water inlet connected to the hot water source rotates from the smaller diameter end of the through hole 141 to the larger end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually increases, and the amount of hot water inflow increases; at the same time, the water blocking member 6 corresponding to the water inlet connected to the cold water source rotates from the larger diameter end of the through hole 141 to the smaller end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually decreases, and the amount of cold water inflow decreases. The amount of hot water entering the valve cavity increases and the amount of cold water decreases, and the temperature of the mixed water in the valve cavity increases.

[0095] For example, when the water temperature is high, the water blocking member 6 corresponding to the water inlet connected to the hot water source rotates from the larger diameter end of the through hole 141 to the smaller end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually decreases, and the amount of hot water inflow decreases; at the same time, the water blocking member 6 corresponding to the water inlet connected to the cold water source rotates from the smaller diameter end of the through hole 141 to the larger end in the corresponding bushing 14, so that the water flow area of ​​the through hole 141 gradually increases, and the amount of cold water inflow increases. The amount of hot water entering the valve cavity decreases and the amount of cold water increases, and the temperature of the mixed water in the valve cavity decreases.

[0096] From the above description and practice, it can be known that the temperature regulating valve provided by the present invention has the following advantages compared with the prior art: the two water inlets are connected to the hot water source and the cold water source respectively, the water outlet supplies water to the user, and the cold water and the hot water are fully mixed in the valve body so that the water outlet provides water at a specified temperature. After reaching the specified temperature, the water outlet supplies water stably. The valve body not only provides the function of regulating the water flow rate, but also provides a space for fully mixing the cold and hot water, outputs the water at a specified temperature, and avoids the influence of the temperature and pressure changes of the inlet hot water or the inlet cold water on the outlet water temperature.

[0097] Those skilled in the art should understand that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit of the present invention should be included in the protection scope of the present invention.
