Description
Technical field
This utility model relates to a kind of chemical apparatuses, particularly to a kind of anti-suck oil vacuole ventilating joint.
Background technology
During chemical experiment aeration, often can use oil vacuole ventilating joint, when anhydrous and oxygen-free operates, generally need
Reaction vessel being carried out evacuation and then leads to the operation of noble gas, before logical noble gas, container is vacuum, in order to prevent sky
Gas suck-back enters reaction system, need to fill an oil vacuole ventilating joint, and traditional oil vacuole ventilating joint pressure in bubbling pipe is less than outward
During boundary's air pressure, in the sealing liquid suck-back being still easily caused in bubbling bottle to bubbling pipe and conical flask, it is allowed to lose fluid-tight effect.
It addition, in chemical experiment, frequently refer to the reaction that gas is participated in or generated, heating gas processed or to having
When poison harmful gas carries out exhaust collection, also through being commonly encountered suck-back phenomenon.The main cause that this suck-back phenomenon produces is airtight
Pressure within system is little, inside and outside generation pressure difference, causes liquid generation suck-back, its consequence or cause the glass of reactor
Burst or suck-back liquid reacts with the product in device, cause the pollution of product.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-suck oil vacuole ventilating joint, can effectively prevent
Sealing liquid suck-back in bubbling bottle.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of anti-suck oil vacuole ventilating joint, bag
Including bubbling bottle, bubbling pipe and escape pipe, described bubbling pipe has head section and a vertical rear of a level, and rear is from top to bottom
Extend to bubbling bottle bottom through bubbling bottle outer wall, head section be communicated with an arm for coupled reaction device, described in go out
Trachea connects on bubbling bottle top, has a spherical hollow space in the middle part of rear.
There is in the middle part of head section a reclinate bending section.
Be provided with check valve in tail end lower end, described check valve includes the connection many semi-circular bend pipes in rear lower end,
Also including the one block of ring glass plate moving up and down being enclosed within rear, when glass plate moves down, glass plate can cover
On the bend pipe mouth of pipe.
Being wrapped with a circle sealing shroud at arm, described sealing shroud is that polytetrafluoroethylmaterial material is made.
The beneficial effects of the utility model are: spherical hollow space forms one on bubbling pipe rear and intercepts cavity, works as bubbling
Sealing liquid in Ping is by time in suck-back to spherical hollow space, and because spherical hollow space cross-sectional area is big, volume is big, and sealing liquid suck-back enters spherical hollow space
After, in bubbling bottle, sealing liquid liquid level is gradually reduced, until disengaging with the bubbling pipe rear lower end mouth of pipe, and the sealing liquid in spherical hollow space
Between liquid level and the spherical hollow space upper end mouth of pipe, formation one is every dead level, and along with the continuation of suck-back, the sealing liquid in spherical hollow space is by certainly
Body action of gravity natural back flow is in conical flask, and then can play good anti-suck effect；Bending section energy in the middle part of head section
Stockpiling a small amount of sealing liquid, the sealing liquid in bending section can reduce the gas gap excessively in the middle part of head section, serves restriction effect, further
Prevent sealing liquid suck-back；Check valve, when sealing liquid suck-back, the bend pipe mouth of pipe can be sealed by glass plate because of gravity, prevents
Sealing liquid is flowed in bubbling pipe from bend pipe, further prevents sealing liquid suck-back to enter bubbling pipe；The effect of sealing shroud is not
Only can improve the sealing effectiveness between arm and conical flask, and overcome glass stopper easy and glass under corrosive conditions
The problem that interface sticks together.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is main TV structure schematic diagram of the present utility model,
Fig. 2 is this utility model perspective view about check valve,
Fig. 3 is this utility model main TV structure schematic diagram in use.
In figure: bubbling bottle 1, bubbling pipe 2, escape pipe 3, arm 4, rear 21, head section 22, spherical hollow space 23, bending section 24,
Bend pipe 25, glass plate 26, every dead level 27.
Detailed description of the invention
If Fig. 1 is to shown in 3: a kind of anti-suck oil vacuole ventilating joint, including bubbling bottle 1, bubbling pipe 2 and escape pipe 3, described
Bubbling pipe 2 has head section 22 and a vertical rear 21 of a level, and rear 21 extends to through bubbling bottle 1 outer wall from top to bottom
Bubbling bottle 1 bottom, is communicated with an arm 4 for coupled reaction device in head section 22, and described escape pipe 3 connects at bubbling bottle
1 top, has a spherical hollow space 23 in the middle part of rear 21.
Spherical hollow space 23 forms one on bubbling pipe 2 rear and intercepts cavity, when the sealing liquid in bubbling bottle 1 by suck-back to ball
Time in shape cavity 23, because spherical hollow space cross-sectional area is big, volume is big, after sealing liquid suck-back enters spherical hollow space, and sealing liquid liquid in bubbling bottle
Face is gradually reduced, until disengaging with the bubbling pipe rear lower end mouth of pipe, on the sealing liquid liquid level in spherical hollow space and spherical hollow space
Between the end mouth of pipe, formation one is every dead level 27, and along with the continuation of suck-back, the sealing liquid in spherical hollow space 23 is by self gravitation effect certainly
So it is back in bubbling bottle 1, and then good anti-suck effect can be played.
There is in the middle part of head section 22 a reclinate bending section 24.
Bending section 24 in the middle part of head section 22 can stockpile a small amount of sealing liquid, and the sealing liquid in bending section 24 can reduce in head section 22
Gas gap is crossed in portion, plays certain restriction effect, further prevents sealing liquid suck-back.
Be provided with check valve in tail end lower end, described check valve includes the connection many semi-circular bend pipes in rear 21 lower end
25, also include the one block of ring glass plate 26 moving up and down being enclosed within rear 21, when glass plate 26 moves down, glass
Plate 26 can cover on bend pipe 25 mouth of pipe.
Check valve, when sealing liquid suck-back, bend pipe 25 mouth of pipe can be sealed by glass plate 26 because of gravity, further prevents
Stop sealing liquid to be drawn in bubbling pipe 2.
Being wrapped with a circle sealing shroud 41 at arm 4, described sealing shroud 41 is made for polytetrafluoroethylmaterial material.
Politef has excellent corrosion resistance, and the sealing shroud 41 using polytetrafluoroethylmaterial material to make is possible not only to
Improve the sealing effectiveness between arm 4 and reactor, and overcome glass stopper easy and glass interface under corrosive conditions
The problem sticked together.
