Sometimes, the seat surface of the valve seat is not sealed at once, but is partially sealed sequentially, so that the hunting phenomenon can be effectively eliminated.
- the third aspect of the invention provides a control valve element 3 that is held in a suspended state by two panels of a noiser panel 4 and a temperature-sensitive panel 5, and moves the control valve element 3 during the control operation.

- the lower guide g2 the lower end of the control valve 3 In addition, they are connected together so that they also extend, and this is inserted into the guide tube 27 provided with the lumen of the valve seat bracket 2b.
- the guide cylinder 27 into which the lower guide g2 is inserted is formed so that its inner diameter slightly increases as it is directed toward one end side (outer end side).
- the lower guide g2 is guided with the upper end side of the guide cylinder 27 as a fulcrum. Inclination and rotation can be performed by an amount corresponding to the increase in the inner diameter of 27. By this inclination and rotation, the control valve body 3 is smoothly guided so as to be displaced to the side opposite to the eccentric side.
- Fig. 1 is a cross-sectional plan view of a hot and cold water mixing tap in a form in which a conventional control valve body is supported by a balance of two panels.
- FIG. 2 is a cross-sectional view of the main part of the above.
- FIG. 3 is a longitudinal cross-sectional view of an embodiment of a hot and cold water mixing tap for carrying out the means of the present invention.
- FIG. 4 is an explanatory view of a yarn wiping process of the embodiment described above.
- FIG. 5 is a cross-sectional view showing a state in which an adjustment screw and a pulling panel are further assembled to the above unit.
- FIG. 6 is an explanatory diagram of a process of assembling the above unit to the main body of the casing.
- FIG. 7 is a cross-sectional view of the above-described embodiment in a state where mixed water is set to be discharged.
- FIG. 8 is a cross-sectional view of the above-described embodiment in a state where hot water discharge is set.
- FIG. 9 is a cross-sectional view showing a state where water discharge is set in the embodiment.
- FIG. 10 is a longitudinal sectional view of another embodiment.
- FIG. 11 is a longitudinal sectional view of the valve seat bracket of the embodiment.
- FIG. 12 is a longitudinal sectional view of the valve seat bracket of the embodiment same as the above and a control valve body that collides with the valve seat bracket.
