Abstract
An experimenting apparatus for collecting a plurality of bottles of gas at one time comprises a three-way pipe, which is characterized in that the three-way pipe is a forked three-way pipe whose two branch pipes are connected with two rubber catheters. The two rubber catheters are separately connected with two forked three-way pipes, and the four branch pipes of the two forked three-way pipes are separately connected with four rubber catheters with shape-nose catheters. Compared with the prior art, the utility model is characterized in simple structure, easy operation and convenient usage. The phenomenon is obvious during the experiment of demonstrating the oxygen's chemical property. The utility enhances the utilization ratio of the medicine, shortens the demonstrating time in class and mobilizes the thinking enthusiasm of the students.
Description
Technical field
The utility model relates to a kind of device of collecting gas, particularly relates to a kind of experimental provision that once can collect many bottles of gases, belongs to chemical experiment device.
Background technology
The teacher runs into the chemistry class that lecture experiment is arranged, and often instructional blocks of time is held and is forbidden, and be difficult to finish the classroom instruction task.Cause the main cause of this situation to be: the operating time of some lecture experiment is longer.For example, during explanation junior middle school " chemistry " chapter 1 second joint " chemical property of oxygen ", requirement of experiment can before make oxygen, but because the loss of gas, during the chemical property experiment of demonstration oxygen, phenomenon is not obvious, if now-making-now-using on the classroom though phenomenon is obvious, is collected many bottles of oxygen length consuming time, be difficult to finish the teaching task of a class hour, teaching efficiency is also bad.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improves by research, provides a kind of experimental provision that once can collect many bottles of gases.This novel experimental provision making simple in structure, easy, easy to use was both shortened the operating time, can reach better teaching again.
The technical scheme that the utility model provides is: this experimental provision that once can collect many bottles of gases, include three-way pipe, be characterized in that described three-way pipe is the forked type three-way pipe, connect two slat gum conduits respectively on two arms of this forked type three-way pipe, these two rubber catheters connect two forked type three-way pipes again respectively, connect the rubber catheter of four band sharp nozzle canulas on four arms of these two forked type three-way pipes respectively.
In technique scheme, the rubber catheter of the forked type three-way pipe that is adopted, rubber catheter and band sharp nozzle canula is apparatus common in the chemical experiment, should belong to prior art so no longer describe in detail.
Compared with prior art, the beneficial effects of the utility model are: tool is deposited simple in structure, easy making, characteristics easy to use, and phenomenon is obvious when the chemical property experiment of demonstration oxygen, has improved the utilization rate of medicine, shorten the class demonstration time, also transferred student's thinking enthusiasm.
Description of drawings
Accompanying drawing is the user mode schematic diagram that the utility model provides embodiment.
The specific embodiment
As shown in the figure, this experimental provision that once can collect many bottles of gases, include the forked type three-way pipe, connect two slat gum conduits 2 respectively on two arms of described forked type three-way pipe 1, these two rubber catheters 2 connect two forked type three-way pipes 3 again respectively, connect the rubber catheter 4 of four band sharp nozzle canulas on four arms of these two forked type three-way pipes 3 more respectively.
When demonstration adopts the gas drainage to collect oxygen, change the single hole plug conduit of former use into forked type three-way pipe 1, connect two slat gum conduits 2 on two arms of this forked type three-way pipe 1 respectively, these two rubber catheters 2 connect two forked type three-way pipes 3 again respectively, two forked type three-way pipes 3 connect the rubber catheter 4 of four band sharp nozzle canulas more respectively, again this device and oxygen generator are coupled together, be that the person in charge of forked type three-way pipe 1 passes the stopple of the glass tube 6 of containing chemical reagent and probes in the glass tube 6, the rubber catheter 4 of four band sharp nozzle canulas inserts four gas bottles 7 interior weights of being inverted in the water 5 that also press respectively in the device, avoid bottle 7 overturnings, the whole loss of oxygen in the bottle.After adopting the utility model, utilize original oxygen generator again, once can collect many bottles of gases simultaneously.
Claims (1)
1. the experimental provision that once can collect many bottles of gases, include three-way pipe, it is characterized in that described three-way pipe is the forked type three-way pipe, connect two slat gum conduits respectively on two arms of this forked type three-way pipe, these two rubber catheters connect two forked type three-way pipes again respectively, connect the rubber catheter of four band sharp nozzle canulas on four arms of these two forked type three-way pipes respectively.
