Technical field
The present invention relates to a kind of chemical experiment gas collecting apparatus, more particularly, to a kind of pressure adjustable based on magnetic rheology effect
The chemical experiment gas collecting apparatus of control.
Background technology
As science and technology is less than progress, the chemical research experiment of scientific research personnel's expansion deepens continuously, more and more
Unknown materials are found, since we are the processes recognized from initial perceptual knowledge to rationality to the understanding of novel substance, if
Quickly it can be understood at the beginning of having a kind of experimental provision let us to be found from novel substance, then entire reality will be promoted
The process tested accelerates the efficiency of experiment.Particularly, for gas, most common collection mode be by gas bottle into
Row is collected, and if there is a kind of device, us can be helped to recognize the pressure of the gas being collected during gas is collected
If force characteristic, the speed of experiment will be greatly improved, valuable time is saved for researchers.
Magnetorheological fluid is made of micron order ferromagnetic particle, base fluid, additive.Under the conditions of zero magnetic field intensity, magnetic current
Become liquid and shows as good fluidity, the low New ton fluids of viscosity, under conditions of having externally-applied magnetic field, the instantaneous (millisecond of magnetorheological fluid
Magnitude) to high viscosity, the Bingham transitional fluids of lazy flow.Research shows that the shear yield stress of magnetorheological fluid can reach
50-100KP, for operating temperature range between -40 DEG C -150 DEG C, the Reversible Cycle change frequency of magnetorheological fluid is about 3,000,000
Secondary, therefore, the chemical experiment gas collecting apparatus of the pressure adjustable control based on magnetic rheology effect has long lifespan, is swift in response, works
The features such as temperature range is wide, and air pressure adjustable range is big.
It is operated under shear mode, the damping force of magnetorheological fluid can be calculated with following formula：
In formula：Viscosity (slope of shear stress after the surrender of actual measurement) after the liquid surrender that η is and magnetic field intensity is unrelated；ν
For the shear strain rate of fluid；τyFor mangneto shear yield stress；Sgn (ν) considers the reciprocating motion of piston.
Invention content
The chemical experiment gas collecting apparatus for the pressure adjustable control based on magnetic rheology effect that the object of the present invention is to provide a kind of, should
Device is mainly used for observation and judges whether pressure has an impact the gas in gas bottle in chemical experiment.
In order to effectively realize that function as described above, the present invention are realized as follows：The device is mainly
By head cover, piston, bolt, magnetorheological fluid, shell, cage ring, electromagnetic coil, piston cap, gas bottle, air inlet pipe, exhaust bottle, row
Tracheae, pressurizer and sealing ring composition.Head cover, shell, gas bottle are bolted, and piston cap, piston, air inlet pipe are solid
Connect together, pressurizer is embedded in inside piston, and head cover is provided with through-hole, sealing ring is set in the through-hole, the sealing ring with into
Tracheae forms prismatic pair, and head cover, shell, piston cap form sealing space, and magnetorheological fluid riddles this sealing space, and piston is opened
There is annular groove, magnetorheological fluid is isolated with electromagnetic coil around wherein, and by cage ring for electromagnetic coil, and gas bottle side is provided with
Aperture, and be connected with exhaust bottle by exhaust pipe.
The size of current being passed through in electromagnetic coil is adjusted, space generates the magnetic field of some strength, magnetic where magnetorheological fluid
Rheological phenomena occurs for rheology liquid so that and magnetorheological fluid has certain shear yielding power, therefore, if it is desired to piston cap moves,
Have to make the gas in gas bottle to be more than under the electric current shear yielding power possessed by magnetorheological fluid to the pressure of piston cap,
When the gas that outside chemical reaction generates flows into gas bottle by air inlet pipe, continuous with gas flows into so that in gas bottle
Gas pressure constantly increases, and until being more than shear yielding power possessed by magnetorheological fluid, magnetorheological fluid is flowed by damp channel
In pressurizer, piston cap is pushed to move up, gas is expelled to exhaust bottle, the gas in gas bottle by gas by exhaust pipe
Drops.Therefore, we can adjust the size of current in inflow electromagnetic coil to control magnetorheological fluid shear yielding power in advance
Size so that the yield force slightly larger than we want observe gas pressure, in this way we could want at us
The variation that gas is observed under pressure, as the continuous of gas flows into so that the pressure in gas bottle constantly increases after observe,
Finally gas is discharged.It is unlikely to whole device and is damaged since air pressure is overloaded.
The present invention be based on magnetic rheology effect, therefore, the present invention have long lifespan, be swift in response, operating temperature range it is wide,
The big feature of pressure regulation spectrum.
Description of the drawings
Fig. 1 is the principle schematic diagram of the present invention.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of chemical experiment gas collecting apparatus of the pressure adjustable control based on magnetic rheology effect of the present invention is main
It is by head cover 1, piston 2, bolt 3, magnetorheological fluid 4, shell 5, cage ring 6, electromagnetic coil 7, piston cap 8, gas bottle 9, air inlet
Pipe 10, exhaust bottle 11, exhaust pipe 12, pressurizer 14, sealing ring 15 form.Head cover 1, shell 5, gas bottle 9 pass through bolt 3
Connection, piston cap 8, piston 2, air inlet pipe 10 are fixed together, and pressurizer 14 is embedded in 2 the inside of piston, and head cover 1 is provided with logical
Hole sets sealing ring 15 in the through-hole, which forms prismatic pair, head cover 1, shell 5, the formation of piston cap 8 with air inlet pipe 10
Sealing space, magnetorheological fluid 4 riddle this sealing space, and piston 2 is provided with annular groove, and electromagnetic coil 7 passes through around wherein
Cage ring 6 is isolated by magnetorheological fluid 4 with electromagnetic coil 7, and 9 side of gas bottle is provided with aperture, and passes through exhaust pipe 12 and exhaust bottle
11 are connected.
The size of current being passed through in electromagnetic coil 7 is adjusted, the magnetic field of some strength is generated in 4 place space of magnetorheological fluid
13, rheological phenomena occurs for magnetorheological fluid 4 so that magnetorheological fluid 4 has certain shear yielding power, therefore, if it is desired to piston
Lid 8 moves, it is necessary to so that the gas in gas bottle is more than under the electric current possessed by magnetorheological fluid 4 pressure of piston cap 8
Shear yielding power flows into gas bottle 9, with the continuous inflow of gas when outside chemical reacts the gas generated by air inlet pipe 10
So that the gas pressure in gas bottle 9 constantly increases, until being more than shear yielding power possessed by magnetorheological fluid 4, magnetorheological fluid 4
It is flowed into pressurizer 14 by damp channel, pushes piston cap 8 to move up, gas is discharged by exhaust pipe 12 for gas
To exhaust bottle 11, the air pressure in gas bottle 9 declines.Therefore, we can adjust the size of current flowed into electromagnetic coil 7 in advance
To control the size of 4 shear yielding power of magnetorheological fluid so that the yield force wants the pressure of the gas of observation slightly larger than us,
We could observe the variation of gas under the pressure that we want in this way, make with the continuous inflow of gas after having observed
Pressure in gas bottle 9 constantly increases, and finally gas is discharged.It is unlikely to whole device and is damaged since air pressure is overloaded.
