Dropping funel, which two kinds of liquid reagents can be added dropwise at the same time can also be used alone a tube body, and easily examine
Survey the temperature of added liquid.
In order to solve the problems existing in background technology, a kind of new double-pipe body constant pressure addition leakage of the utility model
Bucket, it includes upper interface, tube body, cock, collecting pipe, T-shaped constant pressure pipe, thermometer and lower interface；Described T-shaped constant pressure pipe or so
Both sides are arranged with two tube bodies, and T-shaped constant pressure pipe both ends are connected with the inside of tube body, and the top of tube body is equipped with upper interface, tube body
Bottom be equipped with collecting pipe, the collecting pipe of left and right two is interconnected and minimum end opening is located inside T-shaped constant pressure pipe, and T-shaped is permanent
The bottom of pressure pipe is equipped with lower interface, and cock is equipped between tube body and collecting pipe in order to control the flow velocity of liquid, the appearance of tube body
Face is equipped with graduation mark, and thermometer is stretched into inside the least significant end of collecting pipe through T-shaped constant pressure pipe.
As a kind of optimal technical scheme of the utility model, the upper interface is frosted interface, in order to ground
Plug is combined and sealed.
As a kind of optimal technical scheme of the utility model, the lower interface is frosted interface, in order to flask
Ground combine sealed.
As a kind of optimal technical scheme of the utility model, the least significant end of the collecting pipe is equipped with sharp mouth structure, with
Prevent from hanging liquid, it is ensured that liquid communication is smooth
As a kind of optimal technical scheme of the utility model, the cock is made of polytetrafluoroethylene (PTFE), has acidproof
The advantages of alkali, anti-oxidant, nonhazardous.
The utility model has the beneficial effect that：Constant pressure titration funnel can be adjusted according to the demand of actual conditions, full
The demand of different liquids is added dropwise in foot；And there are two tube bodies, improve the utilization ratio of flask interface；Bottom is equipped with confluence
Pipe, for carrying out liquid premix observation drop speed；It is used for surveying inlet temperature equipped with thermometer, it is ensured that feed liquor temperature meets instead
It should require；Centre is more preferable equipped with T-shaped constant pressure pipe constant pressure effect, and simple and reasonable, use is very convenient, is worth pushing away on a large scale
Extensively.
