Pressure）, open atmospheric pressure after piston and the liquid in beaker be pressed into flask, fountain is formed in sharp nozzle canula mouthful.The experiment entertaining
The strong, visual effect of property is good, has surmounted the fountain experiment scope arranged in teaching material, has developed into a series of fountain experiment.
The structural representation of traditional gas fountain experiment device is shown in Fig. 1.The device needs to collect gas in advance, tested
Journey is cumbersome, operating difficulties, experimental phenomena be not obvious, and mounting stability is poor, the progress and effect of experiment is had a strong impact on, while also limiting
Application of the laboratory apparatus in different experiments environment is made.
The content of the invention
The purpose of this utility model is that there is provided a kind of double fountain experiment dresses of three Room gas the problem of presence for prior art
Put.
The double fountain experiment devices of three Room of the present utility model gas, including reative cell, the top of reative cell are provided with charge door,
The rubber stopper of dropping funel and conduit is provided with charge door；Small beaker is mounted with immediately below charge door；The two of reative cell
Side is respectively arranged with transparent left fountain room, had and left fountain room, the right side on right fountain room, and two side walls of reative cell
The aperture that fountain room is communicated；Left fountain mouthful, left fountain mouthful, and left fountain mouthful, a left side are provided with the bottom of left fountain room, right fountain room
Fountain is intraoral to be separately installed with the rubber stopper with sharp nozzle canula；Left fountain room is stretched into, in right fountain room in one end of sharp nozzle canula, separately
One end is connected with rubber tube, and below the liquid of the rubber tube respectively in the large beaker for the side of being inserted under；Rubber tube is provided with bullet
Spring is pressed from both sides, for control operation.
A bit of rubber tube is connected on the top of conduit and is clamped with spring clip, the bottom of other end intercalation reaction room, but
Do not contact bottom.
Whole device is fixed on an inverted T shaped frame.
Double fountain phenomenons can be presented in experimental provision of the present utility model, and interesting strong, simple to operate, phenomenon is bright
Aobvious, functional diversities can do fountain experiment device, be also used as the double Property Verification devices of gas, expand experimental provision
Suitable environment in experimental implementation.
Brief description of the drawings
Fig. 1 is the structural representation of traditional gas fountain experiment device；
Fig. 2 is the structural representation of the double fountain experiment devices of the Room multifunctional gas of the utility model three.
Embodiment
Below in conjunction with the accompanying drawings to the structure and experimental implementation of the double fountain experiment devices of the Room multifunctional gas of the utility model three
Process is described further.
Reference picture 2, a kind of double fountain experiment devices of three Room multifunctional gas, including reative cell 1, on the top of reative cell 1
Provided with charge door 2, the rubber stopper of dropping funel and conduit 3 is provided with charge door 2；The underface of charge door 2 is mounted with small
Beaker.The top of conduit 3 connects a bit of rubber tube and clamped with spring clip, the bottom of other end intercalation reaction room 1, but does not connect
Bottom out portion.Transparent left fountain room 5-1, right fountain room 5-2 are respectively arranged with the both sides of reative cell 1, and in left and right fountain room
Bottom be respectively equipped with left fountain mouthful 7-1, left fountain mouthful 7-2, and left and right fountain it is intraoral be separately installed with band sharp nozzle canula 6-1,
6-2 rubber stopper；One end of the sharp nozzle canula is respectively protruding into left and right fountain room, and the other end is connected with rubber tube, and the rubber
Below the liquid of pipe respectively in large beaker 9-1,9-2 of the side of being inserted under；Rubber tube is provided with spring clip 8-1,8-2, for controlling
Experimental implementation processed.Whole device is fixed on an inverted T shaped frame.
Open aperture 4-1,4-2 by being communicated with left and right fountain room respectively on two side walls of reative cell 1, make reative cell
（1）, left fountain room 5-1, right fountain room 5-2 gases communicates.
Reative cell, left and right fountain room are lucite product.
The course of work of the present utility model：Control the drop speed of dropping funel to be reacted, gas is respectively filled with left and right spray
Spring clip is closed after spring room 5-1 and 5-2.Sharp nozzle canula 6-1,6-2 rubber tube connected are inserted to the liquid of lower section large beaker respectively
Below body.A small amount of water is added into reative cell from dropping funel, spring clip 8-1 and 8-2 is opened, you can it was observed that double fountains.
If the density of the density ratio air of the gas prepared is big, spring clip 8-1 and 8-2 are opened, is leaked by controlling dropping liquid
Struggle against and add reactant in the small beaker into reative cell, its reactant reaction with being held in beaker is produced gas and is excluded sky
Gas.
If the density of the density ratio air of the gas prepared is small, the spring clip and sharp nozzle canula one on the top of conduit 3 are opened
The spring clip 8-1 and 8-2 at end, by controlling to add reactant in beaker of the dropping funel into reative cell, make its with beaker
The reactant reaction held produces gas and excludes air.
Illustrate specific operation process of the present utility model by taking the double fountain experiments of the gas of ammonia as an example below：
Added in flask into reative cell in appropriate calcium oxide solid, dropping funel and load a small amount of concentrated ammonia liquor.By spring
Folder 8-1,8-2 and the spring clip on the top of conduit 3 are opened, and are controlled the drop speed of dropping funel to carry out reaction and are produced ammonia and exclude sky
Gas.After ammonia is full of reative cell and left and right fountain room, 3 spring clips are turned off.The rubber that sharp nozzle canula 6-1,6-2 are connected
Leather hose is inserted below the liquid level of the copper-bath in the beaker of lower section and phenolphthalein solution respectively.Added from dropping funel into reative cell
Enter a small amount of water, the fluid sulphuric acid copper and phenolphthalein solution opened in spring clip 8-1 and 8-2, beaker are sucked up, you can it was observed that double
Fountain phenomenon.
The list that device carries out the fountain experiment of gas see the table below：
