Abstract
The utility model relates to a separating funnel which comprises a spherical container (1), wherein the top of the spherical container is provided with a liquid inlet (2) which is communicated with a cavity (11) in the spherical container, a top plug (3) which seals the liquid inlet is inserted in the liquid inlet, the bottom of the spherical container is provided with a liquid outlet tube (4) which is communicated with the cavity in the spherical container, and the middle part of the liquid outlet tube is provided with a funnel switch (5); and the separating funnel is characterized in that the upper part of the spherical container (1) is also provided with an emergency gas vent (6) which is communicated with the hollow cavity in the spherical container, and an end cover (7) is arranged at the emergency gas vent (6) for sealing. When the separating funnel is normally used, the end cover covers the emergency gas vent to maintain a sealing state, if the separating funnel is operated, the funnel switch instead of the top plug on the spherical container is opened at first by mistake, the separating solution drips, negative pressure can be generated in the spearing funnel, at the moment, the end cover on the emergency gas vent can be opened to enable inner pressure and outer pressure of the spherical container to be the same, the separating solution can smoothly drip through a discharge pipe, so the test process is completed.
Description
Technical field
The utility model relates to a kind of chemical test vessel, relates in particular to a kind of separatory funnel.
Background technology
In chemical test, adopt separatory funnel to carry out extraction, the isolated or purified of material usually.The structure of existing separatory funnel is all similar; Generally comprise spherical container; The top of spherical container has the inlet that communicates with the spherical container internal cavities; Be inserted with the top plug with the inlet sealing in the inlet, the bottom of spherical container has the drain pipe that communicates with the spherical container internal cavities, and the middle part of drain pipe is provided with the funnel switch.
Like a patent No. is the Chinese utility model patent " a kind of air guide separatory funnel " of ZL01258229.8 (notification number is CN2510155Y); The patent No. is the Chinese utility model patent " separatory funnel " of ZL200420120307.7 (notification number is CN2752242Y); The patent No. is the Chinese utility model patent " separatory funnel " of ZL201020286553.5 (notification number is CN201857255U), and they have all disclosed the essentially identical separatory funnel of structure.
It is following to carry out the separatory operating process with separatory funnel: the funnel switch cuts out; Pour two immiscible liquid again in the inlet into; Mode through manual work is hand is carried out mixing with immiscible liquid, lets it static then, makes the liquid natural layering of Different Weight ratio; Through the regulation and control of funnel switch, layering obtains the solution that is separated in regular turn again.
But there is a drawback in traditional separatory funnel; If forget for the moment the top plug of opening earlier on the spherical container, and what open is the funnel switch, lets separation solution drip through drain pipe; Will form negative pressure in the separatory funnel; Finally cause separation solution not drip, the top plug on the spherical container also is difficult to open simultaneously, and chemical experiment can't be carried out smoothly.
Summary of the invention
Even the utility model technical problem to be solved is a kind of maloperation that occurs to be provided, the separatory funnel that also can solution dripped to above-mentioned prior art present situation from drain pipe.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of separatory funnel; Comprise spherical container; The top of spherical container has the inlet that communicates with the spherical container internal cavities; Be inserted with the top plug with the inlet sealing in the inlet, the bottom of spherical container has the drain pipe that communicates with the spherical container internal cavities, and the middle part of drain pipe is provided with the funnel switch; It is characterized in that: the top of said spherical container also is provided with the emergent gas vent that communicates with the spherical container internal cavities, and emergent gas vent place is provided with end cap seal.
Above-mentioned emergent gas vent is the spiral mouth, and said end cap is threaded on this emergent gas vent.The mode that the end cap employing is threaded is connected on the emergent gas vent has the advantage of being convenient to open.Pouring end cap into can also adopt the mode of buckle to be connected with emergent gas vent.
Compared with prior art, the advantage of the utility model is: the top of spherical container also is provided with the emergent gas vent that communicates with the spherical container internal cavities, and the gas vent place is provided with end cap seal; During normal the use, end cap covered on emergent gas vent keep sealing state, if at the operation separatory funnel; Forget for the moment and open the top plug of opening earlier on the spherical container, and what open is the funnel switch, let separation solution drip; Will form negative pressure in the separatory funnel, then be to make the external and internal pressure of spherical container identical through opening the end cap on the emergent gas vent; Separation solution is dripped through drain pipe smoothly, accomplish process of the test.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, be a preferred embodiment of the utility model.
A kind of separatory funnel; It is generally glass material, comprises spherical container 1, and the top of spherical container 1 has the inlet 2 that communicates with spherical container internal cavities 11; Be inserted with top plug 3 in the inlet 2 with the inlet sealing; The bottom of spherical container 1 has the drain pipe 4 that communicates with spherical container internal cavities 11, and the middle part of drain pipe 4 is provided with funnel switch 5, more than is the conventional structure of separatory funnel.
Mainly being improved to of the utility model: also be provided with the emergent gas vent 6 that communicates with the spherical container internal cavities on the top of spherical container 1; Emergent gas vent 6 in the present embodiment is the spiral mouth; Promptly the periphery wall of emergent gas vent is provided with external screw thread; Emergent gas vent 6 places are provided with end cap 7 sealings, and end cap 7 adopts the mode that is threaded to be connected on this emergent gas vent 6
During normal the use, end cap covered on emergent gas vent keep sealing state, if at the operation separatory funnel; Forget for the moment and open the top plug of opening earlier on the spherical container, and what open is the funnel switch, let separation solution drip; Will form negative pressure in the separatory funnel, then be to make the external and internal pressure of spherical container identical through opening the end cap on the emergent gas vent; Separation solution is dripped through drain pipe smoothly, accomplish process of the test.
