Abstract
The utility model relates to teaching aids, in particular to a multifunctional gas device. The multifunctional gas device is characterized in that a transparent bottle is arranged, an opening of the bottle is sealed by a rubber plug, a first inserting tube inserted into the bottom of the bottle, a second inserting tube inserted into the upper end portion of the bottle, and a funnel tube inserted into the bottle are respectively arranged on the rubber plug, a valve is arranged on each of the first inserting tube, the second inserting tube and the funnel tube, and the funnel tube is connected with a liquid distribution funnel. The multifunctional gas device is used for teaching experiments like gas preparation, gas collection, gas storage, gas exhausting, gas washing and gas metering, integrates multiple functions and has the advantages of simple structure, convenience in operating, good demonstrating effect and the like.
Description
Technical field
The utility model relates to teaching appliance, particularly a kind of Multifunctional, air body device of simple in structure, easy to operate, good demonstration effect.
Background technology
As everyone knows, the test class is to student's learning knowledge and strengthen understanding very effective, the knowledge of relevant gas aspect particularly, because gas be cannot see, impalpable characteristic, the pupil learns to be difficult for understanding, existing gas test utensil has the single deficiency of performance, and the cleaning of gas, storage, metering etc. all need independent utensil.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to operate, good demonstration effect Multifunctional, air body device is provided.
The utility model can reach by following measure:
A kind of Multifunctional, air body device, it is characterized in that being provided with transparent bottle, the bottleneck of bottle is by rubber stopper seal, be respectively equipped with the filler tube in first conduit of insertion bottle bottom, second intubate of inserting the bottle upper end and the insertion bottle on the rubber plug, be respectively equipped with valve A, C, B on first intubate, second intubate and the filler tube, filler tube is connected with separating funnel.
The utility model can be used to teaching tests such as gas processed, gas collection, gas storage, exhaust, gas washing and amount gas, gathers multi-function in integral whole, and has advantages such as simple in structure, easy to operate, good demonstration effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of Multifunctional, air body device, it is characterized in that being provided with transparent bottle 1, the bottleneck of bottle 1 is respectively equipped with on the rubber plug 2 on filler tube 5, the first intubate 3, second intubate 4 and the filler tube 5 in first conduit 3 of insertion bottle bottom, second intubate 4 of inserting the bottle upper end and the insertion bottle and is respectively equipped with valve A, C, B by rubber plug 2 sealings, filler tube 5 is connected with separating funnel 6, separating funnel 6 and valve are same as the prior art, and this does not give unnecessary details, and operate during use: gas processed: as CO
2, O
2, H
2Deng, valve-off C opens valve A, unplugs the rubber stopper solid of packing into, and liquid flows into from separating funnel, closes B, and the gas of generation is derived from conduit A.Can pass through B valve controlling flow amount, and then control produces the gas speed; Gas collection: this device integrates traditional drainage, the emptying gas method that makes progress, downward emptying gas method, can carry out multiple gases by the turnover direction of control gas and collect, and 1. emptying gas method is collected: close the B valve collection density gas (O bigger than air
2Or CO
2), gas is held into from C, and air brings out from A, the gas (H that collection density is littler than air
2), gas is held into from A, and air brings out from C, and 2. drainage is collected: add water from separating funnel, make a bottle filled with water, close B.Gas is held into from A, and water brings out from C, contains with beaker.Solved traditional drainage, water is many, wet hand, and problems such as complex operation, simple and quick; Store: after collecting full gas, ABC is closed, for a long time stored-gas.The glass sheet lid that has solved on traditional gas bottle does not live gas, easily the problem of gas leakage; Exhaust: traditional gas bottle can't be taken out gas again and probe into character after collecting gas.This device only need be opened the A valve, adds water from separating funnel, just can be gas from the discharge of A end, and experiment such as light and probe into; Gas washing: the liquid that absorbs impurity is housed in the gas bottle, mixed air from C hold into, A brings out; Amount gas: C end is put a graduated cylinder water receiving, and filled with water (also can not filling with) in the bottle: gas is held into from A, and water brings out from C.Surveying the volume of drainage water with graduated cylinder, then is gas volume, and the utility model can be used to teaching tests such as gas processed, gas collection, gas storage, exhaust, gas washing and amount gas, gathers multi-function in integral whole, and has advantages such as simple in structure, easy to operate, good demonstration effect.
