Description
Technical field
The utility model belongs to a kind of instruments used for education, particularly a kind of instrument of demonstrating siphonage.
Background technology
At present, in the teaching process of middle school physics, for more common siphonage, adopt the preach method directly to impart knowledge to one's students usually, the student can't relate to the reality in the life in learning process, more abstract.
The utility model content
The purpose of this utility model is to provide a kind of instrument of demonstrating siphonage, and this instrument can allow the student see the siphonage that flows and produce voluntarily owing to pressure official post liquid intuitively.
To achieve these goals, the technical solution of the utility model is as follows: a kind of siphonage demonstrator, comprise outer container, water tank, bend pipe and rising pipe, the top of outer container is provided with water inlet, and the side of outer container sets out the mouth of a river, and water tank is fixed in the outer container, bend pipe is arranged in the water tank and passes the bottom of water tank, the extension of bend pipe passes water delivering orifice, and water tank is sealed by waterproof material by the bend pipe place of passing, and rising pipe one end is communicated with the other end with water inlet and passes water delivering orifice.
As improvement, on the described rising pipe flow regulator is set, the water inlet of described outer container is provided with funnel.
Be convenient teaching, excite student's learning initiative, the water delivering orifice place of described outer container sets out mouth of a river sleeve pipe, the part that bend pipe and rising pipe pass water delivering orifice is positioned at the water delivering orifice sleeve pipe, the front of outer container is provided with the slotting door of being made by opaque material, and described water tank, bend pipe, rising pipe and funnel are made by transparent material.
The utility model is simple in structure, operates easyly, and effect is obvious, makes the student see siphonage intuitively, has enriched the content of courses.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the outside drawing of the utility model embodiment 2.
Embodiment
As shown in Figure 1, siphonage demonstrator of the present utility model comprises outer container 1, water tank 2, bend pipe 3 and rising pipe 4, and the top of outer container 1 is provided with water inlet 11, and water inlet 11 places are provided with funnel 14, and position on the lower side, the side of outer container 1 sets out the mouth of a river 12.Water tank 2 is fixed in the outer container 1, bend pipe 3 is arranged in the water tank 2 and passes the bottom of water tank 2, the extension of bend pipe 3 passes water delivering orifice 12, water tank 2 is sealed by polytetrafluoroethylraw raw material band by bend pipe 3 places of passing, rising pipe 4 one ends are communicated with the other end with water inlet 11 and pass water delivering orifice 12, and flow regulator 5 is set on the rising pipe 4, are used to adjust the aquifer yield of water pipe 4, when flow regulator 5 passes hour, the water major part in the funnel 14 enters in the water tank 2.Described water tank 2, bend pipe 3, rising pipe 4, funnel 14 are made by transparent organic glass.
When this instrument uses, need debug earlier.Prepare two beakers, a capacity is 500 milliliters, and a capacity is 100 milliliters.At first fill water with 500 ml beakers, slowly pour funnel 14 into, the water that comes out in the funnel 14 is divided into two strands immediately, and one flows into rising pipe 4, and another plume is gone into water tank 2.Regulate flow regulator 5, make water tank 2 interior water just not have the top of bend pipe 3.
During the demonstration of this instrument, fill water with 500 ml beakers, slowly pour funnel 14 into, the water that comes out in the funnel 14 is divided into two strands immediately, and one flows into rising pipe 4, and the water delivering orifice of rising pipe 4 is with 100 milliliters small beaker water receiving, and another plume is gone into water tank 2.When 500 milliliters water in the funnel 14 all drained off, 100 milliliters small beaker had just filled water, and the water in the water tank 2 had not just had bend pipe 3 tops.At this moment, 500 milliliters large beakers are placed on water delivering orifice 12 places, the water in the small beaker is poured into funnel 14 again, the water in the funnel 14 is divided into two strands once more, one flows into rising pipe 4, another plume is gone into water tank 2, when the water surface in the water tank 2 is higher than the top of bend pipe 3, because the pressure outside the bend pipe 3 is greater than the pressure in the bend pipe 3, siphonage has just produced, water in the water tank 2 can all flow out water tank 2 along bend pipe 3, flows in the large beaker at water delivering orifice 12 places, and the water in the large beaker has become 500 milliliters again.
As shown in Figure 2, embodiment 2 is with the difference of embodiment 1: water delivering orifice 12 places of outer container 1 are provided with a water delivering orifice sleeve pipe 13, and water delivering orifice sleeve pipe 13 is opaque, and the part that bend pipe 3 and rising pipe 4 pass water delivering orifice 12 all is positioned at water delivering orifice sleeve pipe 13.The front of outer container 1 is provided with inserts door 15, and it also is opaque inserting door 15.
This embodiment is when demonstration, owing to can't see inner variation, give feeling of people surface: the water of large beaker is entered, and the water that has only a small beaker that comes out is poured the water of this small beaker into again, and what come out is again the water of a large beaker.Increased interesting degree, can motivate students' interest in learning more.
