Accompanying drawing explanation
Fig. 1 is the structural representation of education experiment self-loopa siphoning installation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to instructions word to make those skilled in the art.
As shown in Figure 1, the invention provides a kind of education experiment self-loopa siphoning installation, comprising: discharge casing 1; Water storage tank 2, its inside is provided with common port electrode 3, low level electrode 4 and high level electrode 5, described common port electrode 3, outside described high level electrode 5 and described low level electrode 4 all cover have insulating sleeve to make it can not mutual conduction.Common port electrode 3 and low level electrode 4 partner the low liquid level liquid level of electrode detection, and common port electrode 3 and high level electrode 5 partner the change of electrode detection high liquid level.The test section of described high level electrode 5 is arranged on the nearly opening part of water storage tank 2 inside, and the test section of described low level electrode 4 is arranged on the position a little more than the height of liquid level in water storage tank 2 described at the end of siphon and described discharge casing 1.Discharge casing 1 and water storage tank 2 are transparent cabinet, are convenient to observation experiment result.
Drainpipe, it comprises the first pipeline section 6 be interconnected, N-shaped pipeline section 7 and the second pipeline section 8, one end of described first pipeline section 6 connects a fluid suction head 11 and is placed in bottom described water storage tank 2, described first pipeline section 6 is provided with the arm 9 of an opening obliquely, on described arm, 9 are provided with vacuum pump 10, and vacuum pump 10 can be used for extracting the air in drainpipe, and the lower end of described second pipeline section 8 to extend in discharge casing 1 and is provided with draining valve 12.
Water pump 13, its suction hose 14 is communicated with described discharge casing 1, and its rising pipe 15 is communicated with described water storage tank 2.
In described education experiment self-loopa siphoning installation, also comprise:
Brandreth platform, it comprises base 16, pillar 17 and the little table top 18 be screwed on described pillar, the surface of described pillar 17 is provided with screw thread, described base 16 has fixing capsule means, and described water storage tank 2 is arranged on described little table top 18, and described discharge casing 1 can be placed on described base 16.
In described education experiment self-loopa siphoning installation, described high level electrode 5 is connected with high fluid level control device, and described high fluid level control device also connects described draining valve 12; Described low level electrode 4 is connected with low fluid level control device, and described low fluid level control device also connects described water pump 13 and voice unit.
