Abstract
The utility model discloses a flanged acid and alkali two-in-one titrating tube, which comprises an acid titrating head, an alkali titrating head and a liquid accommodating tube, wherein an external grinding opening is formed at one end , which is away from a liquid accommodating opening, of the liquid accommodating tube; liquid injection openings of the acid titrating head and the alkali titrating head are respectively provided with internal grinding openings matched with the external grinding opening; an upper flange disk is sleeved on the tube wall of, which is close to the external grinding opening, the liquid accommodating tube; and lower flange disks matched with the upper flange disk are respectively sleeved on the tube walls, which are close to the internal grinding openings, of the acid titrating head and the alkali titrating head. The flanged acid and alkali two-in-one titrating tube has a simple structure and is novel in design; and due to flange ports formed by the upper flange disk and the lower flange disks as well as the standard internal grinding openings and the standard external grinding opening, the acid and alkali titrating heads are matched with liquid accommodating tubes with different volumes to meet different use demands, so that the titrating tube is optimized and simplified in an analytical chemistry laboratory.
Description
Technical field
The utility model relates to a kind of chemical apparatus, relates in particular to the two-in-one buret of a kind of flange form soda acid.
Background technology
The buret of Experiment of Analytical Chemistry chamber use at present is made up of acid titrating head and alkali formula titrating head, is divided into the model of several kinds of 50ml and 25ml etc. again according to the capacity that uses.So can not be general because the acid titrating head is different with the structure of alkali formula titrating head; Accessory can not exchange between the not isometric buret; The laboratory must all kinds disposes one by one causes fund to overstock; And in a single day the part parts damages appear in buret, just can only whole buret abandoned to reconfigure and cause waste.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of flange form soda acid two-in-one buret.
To achieve these goals; The technical scheme that the utility model adopts is: the two-in-one buret of a kind of flange form soda acid; Comprise acid titrating head, alkali formula titrating head and liquid-holding pipe; Liquid-holding pipe is provided with outer grinding port away from an end of containing the liquid mouth; The liquid injection port place of acid titrating head and alkali formula titrating head is provided with the interior ground with the outer grinding port coupling respectively, and the tube wall of liquid-holding pipe is arranged with upper flange plate near the outer grinding port place, and the tube wall of acid titrating head and alkali formula titrating head is arranged with the lower flange that matees with upper flange plate respectively near interior ground place.
As preferably, the two-in-one buret of flange form soda acid also comprises fastening assembly, and the assembly that links closely comprises trip bolt and fastening nut.
As preferably, it is fastening that trip bolt penetrated upper flange plate and lower flange and fastening nut successively.
Compared with prior art; The advantage of the utility model is: simple in structure; Novel in design; The interior ground that utilizes flange-interface that upper flange plate and lower flange form and standard and outer grinding port are realized acid base titration head and co-content liquid-holding pipe collocation not to satisfy different user demands, realize optimization that the Experiment of Analytical Chemistry chamber disposes buret and simplification.

Among the figure: 11, liquid-holding pipe; 12, acid titrating head; 13, alkali formula titrating head; 21, upper flange plate; 22, lower flange; 31, outer grinding port; 32, interior ground; 41, trip bolt; 42, fastening nut.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of embodiment as the utility model; Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 4; The utility model comprises acid titrating head 12, alkali formula titrating head 13 and liquid-holding pipe 11; Liquid-holding pipe 11 is provided with outer grinding port 31 away from an end of containing the liquid mouth; The liquid injection port place of acid titrating head 12 and alkali formula titrating head 13 is provided with the interior ground 32 with outer grinding port 31 couplings respectively, and the tube wall of liquid-holding pipe 11 is arranged with upper flange plate 21 near outer grinding port 31 places, and the tube wall of acid titrating head 12 and alkali formula titrating head 13 is arranged with the lower flange 22 that matees with upper flange plate 21 respectively near interior ground 32 places.The two-in-one buret of flange form soda acid also comprises fastening assembly, and the assembly that links closely comprises trip bolt 41 and fastening nut 42.It is fastening with lower flange 22 and fastening nut 42 that trip bolt 41 penetrated upper flange plate 21 successively.
When people use; Can not only pass through the switching that replacing acid base titration head is realized the acid base titration pipe with the design of flanged fitting through the ground and the outer grinding port 31 of standard, and not isometric liquid-holding pipe 11 can also utilize flanged fitting and the design of standard ground to realize and the acid base titration head assembles to satisfy the user demand of experimental implementation to the buret of various models.Realize that the Experiment of Analytical Chemistry chamber is to the optimization of buret configuration and simplification.
Although having combined current taking as is that a most practical and preferred embodiment has been described the utility model; But be to be understood that; The utility model is not limited to the disclosed embodiments, and is intended to contain spirit and interior multiple modification and the equivalent arrangements of scope that is included in accompanying claims on the contrary.
