Gas.
It is understood that drainage and exhaust method, which each exist, is applicable in limitation.The gas humidity being collected into using drainage
Greatly, experimental implementation is relatively complicated；Exhaust method, since gaseous products are as air, majority be it is colorless and transparent, operator is difficult
Gas collection amount intuitively is distinguished, is typically only capable to by virtue of experience to complete to collect operation, to obtain the gaseous products of high-purity, one
The longer used time is spent, second is that also having partial gas product while obtaining high-pure gas product and leaking to
In atmosphere.In addition, there is also the gases being collected into export, uses for subsequent experimental for existing collection method and device
Technical problem.
Summary of the invention
The purpose of the invention of the present invention is to provide a kind of for collecting the gas of physical chemistry experimental gas product
Product tests collection device, and the present apparatus has gas collection easy to operate, No leakage, purity is high, keeps original physical property
Constant technological merit, overcomes the technological deficiency that existing gas collection method is limited to gas properties, and another technological merit is
It is easy to recycle export gaseous products for subsequent experimental.
Gaseous products provided by the utility model test collection device technical solution, and main technical content is: a kind of
Gaseous products test collection device, and the present apparatus includes gas collection portion and pump pressure portion, and the composition in gas collection portion includes wide-mouth bottle, gas collection
Capsule, the tracheae with control valve, wide-mouth bottle bottleneck are sealed by the first sealing bottle cork, and tracheae passes through first sealing bottle cork,
Collect in air bag merging wide-mouth bottle, becomes tracheae pipe end air bag；The pump pressure portion includes the tee tube of the first switching valve of installation
With pump pressure ball, tee tube down tube passes through first sealing bottle cork, and pump pressure ball is connected to the outer branch pipe pipe end of bottle of tee tube.
In above-mentioned overall technical architecture, the pump pressure portion further includes the second wide-mouth bottle, pump pressure air bag, atmosphere
The second tee tube of the second switching valve is managed and is equipped with, the second wide-mouth bottle bottleneck is sealed by the second sealing bottle cork, atmospheric communicating pipe
The second sealing bottle cork is passed through with the second tee tube down tube, pump pressure air bag is placed in the second wide-mouth bottle, becomes the second tee tube down tube
One bottle of tee tube of pipe end air bag, the outer branch pipe connection pump pressure ball of one bottle of the second tee tube, the outer branch pipe of another bottle and gas collection portion is outer
Branch pipe is connected.
Gaseous products disclosed by the utility model test collection device technical solution, and technological merit is: being not necessarily to basis
Gas properties use different collection methods, and reaction gas product collects operating method unification, the other physical performance of collection
Such as humidity is also no longer influenced by unit factor, and collection is easy to operate, gas purity is high, it is often more important that is convenient for subsequent experimental
Export avoids gas collection, letting out of being likely to occur in subsequent experimental export operation using the gaseous products collected
Leakage problem.
Detailed description of the invention
Fig. 1 is an embodiment contexture figure of the utility model.
Specific embodiment
Gaseous products disclosed by the utility model test collection device, and device composition includes gas collection portion and pump pressure portion.Collection
Gas portion, including wide-mouth bottle 3 and with the tracheae 2 of control valve 6, the bottleneck of wide-mouth bottle 3 is sealed by the first sealing bottle cork 13, collects air bag
In 4 merging wide-mouth bottles 3, become the bottle inner tube air bag for passing through the tracheae 2 of the first sealing bottle cork 13, tracheae 2 can be with reaction unit
It communicates, is collected into collection air bag 4 for gaseous products.The pump pressure portion, composition include the three of the first switching valve 5 of installation
Siphunculus 1 and pump pressure ball 7,1 down tube of tee tube therein pass through first sealing bottle cork 13, with sky in the bottle outside collection air bag 4
Between communicate, the outer branch pipe of the bottle of tee tube 1 is connected with pump pressure ball 7, and the outer branch pipe 15 of another bottle is gas outlet.
Operating method:
It is in the best state before the collection in gas collection portion to make in wide-mouth bottle 3 in sum aggregate air bag 4 to be vacuum state, by tracheae 2 and real
Reaction unit is tested to be connected, opening controlling valve 6, the first switching valve 5 close 1 down tube of tee tube, in an experiment, gaseous products by
The inflow of tracheae 2 is collected into collection air bag 4, until required amount, closes control valve 6, complete the collection of gaseous products；When need
When exporting for subsequent experimental, tracheae 2 is connected with subsequent experimental device, by requirement of experiment dosage opening controlling valve 6, first turn
Going to valve 5 makes 1 down tube of tee tube communicate position with pump pressure ball 7, and grip pressure is pumped ball 7 repeatedly, by promoting air pressure in wide-mouth bottle 3,
Force the gaseous products export of collection air bag 4.
In order to keep the export flow for collecting 4 gaseous products of air bag more smooth and steady, the is added in the pump pressure portion
Two wide-mouth bottles 9, pump pressure air bag 8, atmospheric communicating pipe 12 and the second tee tube 11 for being equipped with the second switching valve 14.Second wide-mouth bottle
9 bottleneck is sealed by the second sealing bottle cork 10, and atmospheric communicating pipe 12 and 11 down tube of the second tee tube pass through the second wide-mouth bottle 9
Second sealing bottle cork 10, pump pressure air bag 8 are placed in the second wide-mouth bottle 9, which is 11 down tube pipe end gas of the second tee tube
It is propped up outside 1 one bottles of the tee tube in capsule, the outer branch pipe connection pump pressure ball 7 of one bottle of the second tee tube 11, the outer branch pipe of another bottle and gas collection portion
Pipe 15 is connected.
The operating method of the present embodiment is:
Second switching valve 14 of the second tee tube 11, which is gone to, makes the pipe end of the second tee tube 1 be pumped air bag and pump pressure 7 phase of ball
Logical position, grip pressure is pumped ball 7 repeatedly, reaches suitable pressure in pump pressure air bag 8, and pump pressure air bag 8 is placed in the second wide-mouth bottle 9, first is that
Help intuitively to observe pump pressure 8 pressure size of air bag, also can avoid pump pressure 8 parectasis of air bag.The operation of gas collection portion gas collection
Same as above, when needing to export gas for subsequent experimental, tracheae 2 is connected with subsequent experimental device, by subsequent experimental requirement
The appropriate opening controlling valve 6 of dosage, and the first switching valve 5, which is gone to, makes 1 down tube of tee tube communicate position with the second tee tube 11, rotation
Second switching valve 14 makes 11 down tube of the second tee tube communicate position with 1 one bottles of tee tube outer branch pipes 15, is pumped 8 compressed gas of air bag
Into in wide-mouth bottle 3, collection 4 gaseous products of air bag are forced steadily to export using the High Voltage of pump pressure air bag 8.
