Embodiment 2
As Fig. 4 and Fig. 5, the present embodiment is at hot water intake tunnel 91, hot water effluent's passage 92, cold water intake tunnel 93, the cold water exhalant canal 94 of the stable ceramic piece stem through-hole 90 arranged outside arc of stable ceramic piece 9, hot water intake tunnel 91 is positioned at outside hot water effluent's passage 92 and length (arc length) is greater than the length (arc length) of hot water effluent's passage 92, and cold water intake tunnel 93 is positioned at outside cold water exhalant canal 94 and arc length is greater than the arc length of cold water exhalant canal 94.Offer eccentric hot water control water flow passage 81 and cold water control water flow passage 82 in moving plate stem through-hole 80 periphery of dynamic porcelain piece 8 lower surface, hot water control water flow passage 81 and cold water control water flow passage 82 are processed with decompression through hole 83.Tension force to ceramics when decompression through hole 83 can reduce dynamic pressure (current) is set, strengthens the sealing between dynamic and static ceramics, reduce the frictional force between dynamic and static ceramics simultaneously, improve feel during valve core rotation.Fig. 6 and Fig. 7 is the schematic diagram that between quiet, dynamic porcelain piece, hot water channel and cold water channel are all closed, Fig. 8 with Fig. 9 is the schematic diagram that between quiet, dynamic porcelain piece, hot water channel is communicated with cold water channel.
After hot water, cold water enter ceramics respectively, enter regulator through ceramics through water inlet of hot water 1b, cold water inlet 1c, after mixing pool mixes, mixing water outwards flows out from the mixed water exports 30 of base 3.The dynamic porcelain piece of the present embodiment does not change the water yield of the hot water or cold water entering regulator when rotating, drive constant temperature valve rod by driving lever seat, constant temperature valve rod driving regulator carries out temperature adjustment, and dynamic porcelain piece slides can close or open cold and hot water inlet, adjust flux.
With reference to Figure 10 and Figure 11, it is the top and bottom perspective views of the present embodiment valve core.The entering hot water channel and enter cold water channel and be communicated with up and down of valve core 1, the water inlet end face a1 entering hot water channel and the water inlet end face b1 entering cold water channel are on the bottom surface of valve core and in circular arc (fan-shaped), and the line of the mid point of two sections of circular arcs is as x-axis (lines of two fan-shaped geometric center lines).The water inlet end face c1 of the water outlet end face a2 entering hot water channel, the water outlet end face b2 entering cold water channel, hot-water outlet channel, go out cold water channel water inlet end face d1 on the end face of valve core and in fan-shaped, identical and the circumferentially uniform intervals distribution of the water inlet end face c1 of the water outlet end face a2 entering hot water channel, the water outlet end face b2 entering cold water channel, hot-water outlet channel, the water inlet end face d1 shape size going out cold water channel, enter the water outlet end face a2 relative x-axis deflection angle α of hot water channel, α is between 10 ~ 30 °, and the α of the present embodiment is 20 °.Valve core adopts the structure in four points of water routes, the discharge area of water inlet and water outlet can be increased, thus add the flow of spool, because the position (water inlet end face a1 and water inlet end face b1 position) of water inlet is certain, four points of water routes have rotated between 10 ~ 30 degree, not only can improve the technique of the water inlet of tap, and add discharge area (as shown in dash area in Figure 11, dash area is exactly rotation 20 degree of discharge areas had more).
With reference to Fig. 8, when the relative x-axis deflection of the water outlet end face a2 entering hot water channel, the included angle A between hot water effluent's passage 92 edge and x-axis is 10 °, and the included angle B between cold water exhalant canal 94 edge and x-axis is 43 °, A of the present utility model can between 5 ~ 15 °, and B can between 40 ~ 50 °.Hot water or cold water's exhalant canal on stable ceramic piece, with four points of water route deflection several angles of valve core, can regulate high temperature or low temperature water outlet by regulating the discharge area of hot water or cold water to realize spool.
As shown in figure 12, for full cold water state during the water of pass, now, when the hot water control water flow passage 81 of dynamic porcelain piece staggers with hot water effluent's passage 92 of stable ceramic piece, the cold water control water flow passage 82 of dynamic porcelain piece staggers with the cold water intake tunnel 93 on stable ceramic piece, and hot water and cold water pathway are all closed, with reference to Figure 13, stir driving lever, dynamic porcelain piece is made to slide into open position, the hot water intake tunnel 91 of stable ceramic piece is communicated with hot water effluent's passage 92 by hot water control water flow passage 81, the cold water intake tunnel 93 of stable ceramic piece is communicated with cold water exhalant canal 94 by cold water control water flow passage 82, hot water and cold water pathway are all opened, because hot water effluent's passage 92 has deflected several angle, under full cold water state, hot water control water flow passage 81 does not have not overlap completely with hot water effluent's passage 92 conducting, hot water discharge area is made to be less than cold water discharge area, cold water flow is large, the lowest temperature water outlet of spool is realized when cold water discharge area is maximum.
As shown in figure 14, be all hot water's state during the water of pass, now, when hot water effluent's passage 92 of hot water control water flow passage 81 stable ceramic piece of dynamic porcelain piece staggers, cold water control water flow passage 82 staggers with the cold water intake tunnel 93 on stable ceramic piece, and hot water and cold water pathway are all closed, with reference to Figure 15, stir driving lever, dynamic porcelain piece is made to slide into open position, the hot water intake tunnel 91 of stable ceramic piece is communicated with hot water effluent's passage 92 by hot water control water flow passage 81, the cold water intake tunnel 93 of stable ceramic piece is communicated with cold water exhalant canal 94 by cold water control water flow passage 82, hot water and cold water pathway are all opened, because cold water exhalant canal 94 has deflected several angle, under all hot water's state, the incomplete conducting that do not overlap with cold water exhalant canal 94 of cold water control water flow passage 82, cold water discharge area is made to be less than hot water discharge area, hot water flow is large, the highest temperature water outlet of spool is realized when hot water discharge area is maximum.
Further, hot water control water channel 81 and the cold water control water channel 82 of the present embodiment are fan-shaped, and central angle is 60 °, has maximum discharge area to carry out guaranteed flow when rotating in the switching position to make dynamic porcelain piece.Hot water control water channel 81 can be the same with the shape of cold water control water channel, also can be different, difform hot water control water channel and cold water control water channel is adopted to be identical in order to ensure hot and cold water water inlet area, as in the present embodiment, because hot water control water channel is different from the distance between the center of circle with cold water control water channel, identical in order to ensure hot and cold water water inlet area, hot water control water channel is special-shaped passage, is roughly the fan-shaped of I-shaped.
The amount of extending under the effect of hot and cold water due to thermosensitive element and shorten is certain, the rotation angle of Single-handle dual-control constant-temperaturevalve valve core is generally 120 degree, if ceramics high temperature or discharge area, low temperature position constant, realize the helical pitch that high temperature or low temperature will increase constant temperature valve core, helical pitch crosses the self-locking performance that conference loses screw thread, just causing cannot accurately temperature adjustment, and the present embodiment changes hot water or cold water's area of intaking by stable ceramic piece high/low temperature position under water flowing state and realizes helical pitch one timing spool and can regulate high/low temperature.
