Abstract
The utility model relates to a demonstration instrument for a memory alloy spring. The demonstration instrument comprises a water heater, a pedestal, a transparent glass tank and a panel, wherein the water heater is cylindrical, the transparent glass tank is cuboid-shaped and is made of high-temperature-resistant materials, both the water heater and the transparent glass tank are fixed on the pedestal; the top end of the water heater is provided with a water-heater cover which is flexibly connected with the water heater; the panel is fixedly connected between the water heater and the transparent glass tank, and a first communicating pipe and a second communicating pipe are connected between the water heater and the transparent glass tank in a sealed manner; the panel is provided with a water pumping switch and a heating switch, an electric-powered water pump is mounted in the first communicating pipe, and a water valve is arranged on the second communicating pipe. When the water pumping switch is pressed down, water in the glass tank can be pumped into the water heater by the electric-powered water pump; when the water in the glass tank is pumped out, the water pumping switch automatically bounces, the electric-powered water pump stops working and ensures that the water does not flow back; when the heating switch is pressed down, the water heater keeps heating continuously till the water is boiled up and preserves the temperature after boiling; and a partition plate is arranged slightly higher than the top end of the second communicating pipe in the transparent glass tank, and the partition plate is provided with a plurality of permeable holes.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, relates to a kind of memory alloy spring demonstrator.
Background technology
The characteristic of memory alloy spring is to remember under certain temperature the shape of oneself, during temperature variation, and alteration of form, when getting back to original temperature, memory alloy spring also restores to the original state.The demenstration method of existing memory alloy spring lecture experiment is: memory alloy spring is placed in the plastics basin; In the plastics basin, add hot water; The memory alloy spring shape changes, and pours out the hot water in the basin then, and memory alloy spring slowly restores to the original state again.In whole experiment, will add hot water and fall hot water, not only trouble is also dangerous.
Summary of the invention
In order to solve the problem of existence, the purpose of the utility model provides a kind of memory alloy spring demonstrator, not only safety but also the hot water that need not fall.
The utility model solves the technical scheme that its technical matters adopted: the memory alloy spring demonstrator, comprise water heater, base, clear glass pond, panel, and said water heater is cylindrical; The clear glass pond is cuboid and is processed by exotic material that both all are fixed on the base, and said water heater top is provided with the water heater lid with its flexible connection; Be fixedly connected with panel between said water heater and the clear glass pond, be sealedly connected with first communicating pipe and second communicating pipe, panel is provided with draw water switch and heater switch, in first communicating pipe electric water pump is installed; Second communicating pipe was provided with water valve, pressed the switch that draws water, and electric water pump can be extracted into the water in the aquarium in the water heater automatically; After draining the water in the aquarium; The switch that draws water is upspring automatically, and electric water pump quits work and guarantees that water does not flow backwards, and presses heater switch; Water heater will be heated to water boiling back insulation always; In the clear glass pond, a little more than second communicating pipe top end be provided with dividing plate, dividing plate is provided with a plurality of permeable holes.
During use, be put into memory alloy spring on the dividing plate in the aquarium, close water valve; Open the water heater lid, in water heater, inject an amount of water and build the water heater lid, press heater switch; After treating the water boiling in the water heater, open water valve, the hot water in the water heater is just through flowing in the clear glass pond second communicating pipe; After hot water floods memory alloy spring through a plurality of permeable holes, just can see that the shape of memory alloy spring sharply changes, close water valve; Press the switch that draws water, electric water pump just is extracted into the water in the aquarium in the water heater automatically, after the water in the aquarium is drained; Along with the reduction of temperature, memory alloy spring slowly returns to original state again.
The beneficial effect of the utility model is, simple and convenient practicality, experiment effect obviously, safety.
