As preferably, described water-water jet is the spiral water-water jet that inwall is provided with helical tooth from top to bottom.Hot and cold water is because acting on of pressure and gravity produces swirling flow under the effect of spiral water-water jet spiral fluted, thereby it is full and uniform that hot and cold water is mixed, and guarantees the stable of water-exit temperature, and making the detected temperature of thermosensitive element is the actual temperature of mixed water exports water temperature.
As preferably, described spiral water-water jet be shaped as cylindrical shape.Cylindrical outer wall can be affixed on valve interior wall, and inner chamber then forms desirable helical duct.
As preferably, the pitch of described helical tooth and tooth height ratio are 1～1.5: 1.
As preferably, described helical tooth adopts at least two line spirals.Three-way or the quadruple screw of the preferential employing of described helical tooth.Adopt quadruple screw, it is littler that the increase exhalant canal is used water resistance.
As preferably, establish adjustable lever on the described thermosensitive element, be provided with coil tension spring between adjustable lever upper end and handwheel bottom.Coil tension spring cooperates with the lower end Returnning spring can make moving up and down of thermosensitive element more accurate.
Further improve, described handwheel middle part downside is established the adjusting head, regulates head and is passed down through valve gap, regulate a lower end and establish deep gouge, regulate an outside, lower end and be provided with the screw thread that cooperates with the valve gap inwall, described coil tension spring is located in the deep gouge, and deep gouge and apical grafting coil tension spring are stretched in the adjustable lever upper end.
As preferably, be provided with spool between described thermosensitive element and valve interior wall, described spool expands with thermosensitive element and moves up and down to regulate cold water inlet and hot water inlet's size.Improve the validity of regulating.
As preferably, the sectional shape of described helical tooth is trapezoidal.Help the formation of helical duct.
The utility model is owing to adopted technique scheme, it is full and uniform that the water-water jet that the mixed water exports place establishes mixes hot and cold water, guarantee the stable of water-exit temperature, also making the detected temperature of thermosensitive element is the actual temperature of mixed water exports water temperature, make the mixed water exports water outlet more even, the valve regulated temperature is more accurate.Reduce the valve regulated number of times, improve valve working life.Simple in structure, cost is low, not limited by water temperature.
