Abstract
The utility model provides an acidification device for experiments, its includes parts such as U type cup, cock, cock cover, drain pipe, ground stopper, venthole, there are aperture and U type cup intercommunication in a U type bottom of cup portion and a cock cover body coupling above the cock cover, now have aperture and drain pipe intercommunication, the ground stopper is located the following of cock cover, and the parcel is in the outside of drain pipe, it has the venthole to open in ground stopper lateral wall lower part, the cock is located the cock cover, and the cock is solid cylinder, and the swing handle is connected to one side of cylinder, there are a through -hole and two apertures of cock cover to communicate from top to bottom in the cock. The utility model discloses an advantage: 1, can be through the velocity of flow of cock control liquid to it is controllable to make dilution in -process liberated heat. 2, the ground can feed through with following container seals, makes acidification device and other containers stabilize and is connected, prevents to topple.
Description
Technical field
This utility model relates to the glass device of a kind of use for laboratory, a kind of means for feeding acid specifically tested.
Background technology
At present many experiments need to carry out under strong acid media because concentrated sulphuric acid have extremely strong corrosivity, zest and
Water absorption, mixes with water and can discharge substantial amounts of heat.During so being diluted the operation of concentrated sulphuric acid, concentrated sulphuric acid is slow along chamber wall
In slow injection water, and continuous Glass rod stirs.And in experimentation, if the flow speed control of concentrated sulphuric acid improper with water and other
Reagent generation vigorous reaction, cause bumping, easily cause casualties.
Utility model content
Easily causing the problem of bumping to solve diluting concentrated sulfuric acid process in experiment, this utility model experiment acid adding fills
The technical scheme put is as follows:
A kind of experiment means for feeding acid, it includes the portions such as U-shaped cup, cock, cock set, drain pipe, grinding port plug, venthole
Point, it is characterised in that: being connected with cock set one bottom U-shaped cup, cock set has aperture to connect with U-shaped cup above, has little below
Hole connects with drain pipe；Grinding port plug is positioned at below cock set, is wrapped in the outside of drain pipe；Have in grinding port plug lower sidewall
Venthole；Cock is positioned at cock set, and cock is solid cylinder, and the side of cylinder connects swing handle；A through hole and rotation is had in cock
Two apertures of plug sleeve connect up and down.
When the grinding port plug of this device connects with the sealing of other containers, the liquid of U-shaped cup forms it into the space of sealing, U
The liquid of type cup flows out under gravity, when the gravity of external atmosphere pressure with U-shaped cup liquid self is equal to receptacle gas
During the pressure of body, the liquid of U-shaped cup stands.
According to Boyle's law, now the pressure of gas and volume are inversely.Venthole on grinding port plug makes container
Inside connects with ambient atmosphere, and container internal pressure is equal to atmospheric pressure；Now liquid just can lean on the action of gravity of self to delay
Flow slowly in container below.
The beneficial effects of the utility model:
1, rotate cock, make U-shaped cup become an independent container；Pouring solution into, rotate cock, liquid flows slowly
Under, the flow velocity of liquid can be controlled by cock, so that liberated heat is controlled in dilution.
2, ground can seal with container below and connect, and makes this device and other containers consolidate and is connected, prevents because of instrument
Topple the unexpected injury caused.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 4. drain pipe 5. grinding port plug 6. ventholes are overlapped in cock 3. cock of 1.U type cup 2..
Detailed description of the invention
Embodiment 1
As it is shown in figure 1, a kind of experiment means for feeding acid, it includes U-shaped cup 1, cock 2, cock set 3, drain pipe 4, ground
The parts such as plug 5, venthole 6, are connected with cock set 3 one bottom U-shaped cup 1, have aperture to connect with U-shaped cup 1 above cock set 3,
Aperture is had to connect with drain pipe 4 below；Grinding port plug 5 is positioned at below cock set 3, is wrapped in the outside of drain pipe 4；At grinding port plug
5 lower sidewall have venthole 6；Cock 2 is positioned at cock set 3, and cock 2 is solid cylinder, and the side of cylinder connects swing handle；Rotation
A through hole is had to connect up and down with two apertures of cock set 3 beyond the Great Wall.
