Mode of operation according to fluid mixing valve 1 of the present utility model and fluid flowing are described with particular reference to Fig. 6 A-B, Figure 12 A-C and Figure 13 A-B below. When user such as wishes to regulate water temperature, when this is such as regulated or opened current (switch base) in shower before opening current (switch base), by screw temperature control valve (TCV) bar relative to inner housing component and and then Flow-rate adjustment seat (switch base) rotate, thus changing overlapping area ratio between the first hole of Flow-rate adjustment seat and the adjustment hole of the second hole and temperature control valve (TCV) bar, and then change their discharge area, thus substantially changing the mixing ratio of hot and cold water, it is achieved the change of temperature. Such as, first fluid as shown in Figure 13 B is turned to from the first fluid shown in Figure 12 B, position such as cold water and second fluid, circulation area roughly equal (as mixing ratio is about 1:1) such as hot water, if the circulation area of cold water is more than second fluid, such as the position of circulation area (if mixing ratio is more than 1:1) of hot water.When user such as wishes to regulate flow after opening current, Flow-rate adjustment seat rotates relative to fixed balanced valve mechanism, and temperature control valve (TCV) bar rotates with this Flow-rate adjustment seat, thereby through the flow of the overlapping area (circulation area) and basic synchronization ground change first fluid and second fluid that regulate the first and second holes and the first and second fluid issuings, as synchronized to become greatly or synchronizing to diminish. With reference to Fig. 6 A-B, the first fluid of inflow, such as flow into from first fluid entrance such as cold water, and flow through the first balance inner chamber, first fluid outlet, the first hole and adjustment hole, and enter hybrid chamber. The second fluid that flows into, such as flow into from second fluid entrance such as hot water, and flow through the second balance inner chamber, second fluid outlet, the second hole and adjustment hole, and enter hybrid chamber. This first fluid such as cold water and second fluid such as hot water is mixed to form fluid-mixing such as warm water at this hybrid chamber, and flow out through the side opening of valve rod and the side opening of inner housing component, and the fluid-mixing current drainage channel of the longitudinal extension by being formed between the outer wall of the inwall of shell and the outer wall of inner housing component and balanced valve mechanism (the balance valve casing outer wall such as with installation portion) flows out this fluid mixing valve, and such as pass through in the runner feed line in valve seat, and such as it is sprayed to user or on head.

According in embodiment of the present utility model, it is shown that Flow-rate adjustment seat defines the first valve face of the flow regulating the first and second fluids, and valve rod, specifically adjustment valve plate limit second valve face in the downstream of the ratio regulating the first and second fluids. In an illustrated embodiment, because the frictional resistance applied directly or indirectly to the first valve face, when the second valve face rotates, the frictional force that the first valve face applies is not enough to drive the first valve face concomitant rotation by the second valve face. And because (such as by the first valve face) applies the frictional force to the second valve face directly or indirectly, when the first valve face rotates, this frictional force will drive the second valve face to rotate with the first valve face. Thus, when rotating temperature control valve (TCV) bar to regulate temperature, Flow-rate adjustment seat can't rotate, and then flow remains unchanged, and during rotation flow adjustment seat, temperature control valve (TCV) bar does not change relative to the position of Flow-rate adjustment seat, and then temperature remains unchanged. Apply sealing member that frictional resistance to the first friction generating mechanism of the first valve face such as includes being arranged between shell and inner housing component, such as O and/or the first and second packing rings of touching with Flow-rate adjustment seated connection, but it is contemplated that supplement or substitute other friction generating mechanism, for instance the sealing member set up. Apply a frictional force to sealing member that the second friction generating mechanism of the second valve face such as includes being arranged between valve rod and inner housing component, such as O, but it is contemplated that supplement or substitute other friction generating mechanism, for instance the sealing member set up. Although have employed frictional force frictional force generating mechanism in other words in an illustrated embodiment to configure to the above-mentioned rotation realizing valve rod and interior valve casing group, but it is also contemplated that other means, for instance by means of being used at the releasable fixed mechanism completing to fix after temperature regulates valve rod.
