Embodiment 1
[0034] Embodiment 1 shows a typical application of the temperature switch based on the volume change effect of the phase transition of the low melting point metal of the present invention. figure 1 It is a structural schematic diagram when the temperature switch is in a closed state; figure 2 It is a structural schematic diagram when the temperature switch is in an open state.
[0035] Such as figure 1 and figure 2 As shown, the low melting point metal phase transition temperature switch of the present embodiment consists of a hollow housing 1, a fixed rod 2, a hollow piston 3, a spring 4, and a space 5 filled between the top of the fixed rod 2 and the inner top of the hollow piston 3 The liquid metal composition in
[0036] In this embodiment, a fluid inlet J1 is provided on the side wall of the hollow housing 1 and a fluid outlet C1 is opened on the top wall of the hollow housing 1;
[0037] The fixed rod 2 is vertically fixed on the inner bottom end wall of the hollow...
Embodiment 2
[0046] Embodiment 2 shows a typical application of the temperature switch based on the phase transition volume change effect of the low melting point metal of the present invention as an automobile thermostat; image 3 , Figure 4 A schematic diagram of its structure.
[0047] Such as image 3 and Figure 4 As shown, the structure of the temperature switch based on the low-melting point metal phase transition volume change effect of this embodiment is basically the same as that of Embodiment 1, the difference is:
[0048] A fluid inlet J1 and two fluid outlets (a small circulation outlet Cx located at the bottom of the side wall of the hollow housing 1 and a large circulation outlet Cd located on the top wall of the hollow housing 1) are provided on the hollow housing 1; The heated cooling water of the automobile engine 8 flows in from the fluid inlet J1 located in the middle of the side wall of the hollow casing 1, and the hot water flowing out through the small circulatio...
Embodiment 3
[0053] Example 3 shows a typical application of the temperature switch based on the phase transition volume change effect of the low-melting point metal of the present invention as a thermostatic water mixing valve. Figure 5 A schematic diagram of adjusting the mixing ratio of cold and hot water for the thermostatic mixing valve to ensure a constant outlet water temperature.
[0054] Such as Figure 5 As shown, the structure of the temperature switch based on the volume change effect of the low-melting point metal phase transition in this embodiment is basically the same as that in Embodiment 1, the difference is:
[0055] This embodiment has two fluid inlets (hot water inlet J1 and cold water inlet J2) and one fluid outlet (mixed water outlet C1). Cold and hot water enter from their respective inlets, mix in the water mixing valve, and then flow out through the mixing water outlet C1.
[0056] The materials of the hollow casing 1, the fixed rod 2 and the hollow piston 3 in...
