Embodiment
In Fig. 1, shell 1 middle part is provided with cold water inlet 13 and hot water inlet 14, and the left end of shell 1 is a mixed water exports 16.Box type piston 5 is positioned at shell 1 middle part, and adjustable lever 8 is positioned at shell 1 right-hand member.The right-hand member of adjustable lever 8 is connected with temperature adjustment handwheel 9, and the right-hand member of the left end of adjustable lever 8 and slide block 7 passes through threads engaged.Be equipped with bias spring 6 between the left end of slide block 7 and the box type piston 5.Shell 1 left end that is provided with mixed water exports 16 is built-in with metal temperature control spring 2, is equipped with hollow spring shield 4 between metal temperature control spring 2 and the box type piston 5, and hollow spring shield 4 right-hand members are provided with discharge orifice 3.
(is example with 35 ℃) adjustable lever 8 adjusting sliders 7 move axially when temperature adjustment handwheel 9 rotates to that a certain scale set positions is a certain to blend coolant-temperature gage, bias spring 6 compressions, thus the precompression that box type piston 5 drives 4 pairs of metal temperature controls of hollow spring shield spring 2 produced.
When cold water inlet 13 and hot water inlet 14 can both normal water supplies, when using mixing water, the hot water hot water inlet 14 that flows through rapidly enters shell 1 inner chamber, box type piston 5 hollows of flowing through through hollow spring shield 4 hollows after behind metal temperature control spring 2 temperature-sensitives, flow out through mixed water exports 16.
Metal temperature control spring 2 perception water temperatures in shell 1 inner chamber, produce restoring force rapidly and drive hollow spring shield 4 promotion box type pistons 5 compression bias springs 6, increase the flow that the cold water of introducing cold water inlet 13 enters the discharge orifice 3 of hollow spring shield 4, reduce the flow of the hot water of introducing hot water inlet 14, under the effect of bias spring 6 elastic force, reach balance, box type piston 5 is static.
