Description
Technical field
The utility model is related to chemical experiment fixture technology fields, and in particular to a kind of constant pressure funnel.
Background technology
In laboratory during lab scale PRODUCTION TRAITS, the dropwise addition of reaction reagent is carried out usually using constant pressure funnel,
The structure of existing constant pressure funnel is all similar, generally is the container of glass material, is equipped in the outside of glass funnel
With the glass tubule of holding constant pressure be connected to inside funnel, when with dropwise addition of the constant pressure funnel to carry out reaction reagent, first general
Feed inlet is opened, then inwardly pours into reaction reagent from feed inlet, and the speed of rate of addition is adjusted by the position of regulating switch.
But traditional constant pressure funnel is there are some drawbacks, for example constant pressure funnel is frangible by shaking during dropwise addition, or
Easily constant pressure tubule is smashed when laboratory is placed, constant pressure system is caused to be destroyed, greatly affected research effect, while nothing
The speed of method dropping liquid.
Invention content
It is easy to use the technical problem to be solved by the present invention is to provide a kind of simple in structure, it can effectively avoid easily
The constant pressure funnel of speed broken and that dropping liquid can be accurately controlled.
For the above-mentioned target of realization, the technical solution of the utility model is:A kind of constant pressure funnel, including funnel body,
The cock being arranged on inlet tube, outlet tube and funnel body outlet tube, it is characterised in that:On funnel body surface and outlet tube table
Face has been covered each by glass wall, and interlayer is formed between the glass wall and funnel body on funnel body surface, outlet tube surface point
Interlayer two is formed between glass wall and outlet tube table, interlayer one is connected with interlayer two, and helix tube is surrounded in interlayer one,
The inside that the upper end of helix tube extends to funnel body is connected with funnel body upper end, and lower end extends to the bottom for setting interlayer one
End.
Further, helix tube is hollow spiral glass tube, is fixedly installed in interlayer one.
Further, it is provided with dial at cock.
Further, dial is the data disks with data.
The utility model solves the problems, such as that existing constant pressure funnel is frangible during the reaction, and reaction efficiency is low and auxiliary
The problem for helping facility dependence strong effectively increases product yield and production efficiency and is accurately controlled the speed of dropping liquid.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Drawing explanation:1, funnel body, 2, inlet tube, 3, outlet tube, 4, cock, 5, interlayer one, 6, interlayer two, 7, spiral
Pipe, 8, dial.
Specific implementation mode
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, does not indicate or imply the indicated dress
It sets or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the utility model
Limitation.
It is described in detail the technical solution of the utility model in conjunction with attached drawing, a kind of constant pressure funnel, including funnel body 1,
The cock 4 being arranged on inlet tube 2, outlet tube 3 and funnel body outlet tube is covered respectively on funnel body surface and outlet tube surface
It is stamped glass wall, forms interlayer 1, the glass wall on outlet tube surface point between the glass wall and funnel body on funnel body surface
Interlayer 26 is formed between outlet tube table, interlayer one is connected with interlayer two, and helix tube 7, spiral are surrounded in interlayer one
Pipe is hollow spiral glass tube, is fixedly installed in interlayer one, the upper end of helix tube extend to the inside of funnel body with
Funnel body upper end is connected, and lower end extends to the bottom end for setting interlayer one.
Constant pressure funnel is designed as double-layer structure, helix tube is set in interlayer one, helix tube one end extends to funnel
Body interior, the other end are connected with by interlayer one with interlayer two, when being full of solvent inside funnel body, helix tube connection
With interlayer two inside funnel, pressure constant state is maintained, helix tube is set in interlayer one, avoids common constant pressure addition leakage
Bucket, constant pressure tubule are exposed to outside, the problem of being easy to break up in assembling device and taking and placing in laboratory, increase constant pressure addition
The service life and service life of funnel are provided with dial 8 at cock, and dial is the data disks with data, passes through rotation
Dial is set at plug, and the drop speed of liquid is controlled by the data of data disks.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is new not departing from this practicality
Under the premise of type spirit and scope, the utility model also has various changes and modifications, these changes and improvements both fall within requirement and protect
The scope of the utility model of shield.
