Fig. 1 is the structural representation of titration outfit of the invention.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in detail, it is to be understood that guarantor of the invention
Shield scope is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As shown in figure 1, according to a kind of titration outfit of the specific embodiment of the invention, including buret 1 and drop velocity modulation section
Mechanism 2, buret 1 is on buret stand 3.The fast governor motion 2 of drop includes drop velocity modulation section fixed mount 21, flexible pipe 22 and drop velocity modulation
Section screw rod 23.Drop velocity modulation section fixed mount 21 can slide up and down on buret stand 3, and flexible pipe 22 is located at drop velocity modulation section fixed mount
On 21, the bottom of the upper end correspondence buret 1 of flexible pipe 22 is set.Preferably, flexible pipe 22 is acid and alkali-resistance plastic tube.Drop velocity modulation section is consolidated
Determine frame 21 and be provided with the screwed hole cooperated with drop speed control screw rod 23, drop speed control screw rod 23 is rotatably located at drop velocity modulation
On section fixed mount 21, left part fit settings with the flexible pipe 22, and screw rod, the control flexible pipe are controlled by rotating the drop speed
With the size of the fast adjusting screw rod joint place internal diameter of the drop, and then the controllable flow velocity for flowing out flexible pipe liquid.According to drop velocity modulation section
Screw rod identifies scale, clearly on the fast table of drop to the hose squeezing degree of titrating solution and associating for the fast speed of drop to different drop speed
Clear visual, testing staff drips fast scale size according to the drop speed instruction line correspondence on the spiro rod cap of the fast adjusting screw rod of drop, it is easy to
Control drop speed, controls dropping point terminal exactly.Avoid human error, it is ensured that the accuracy of testing result.
Preferably, the right-hand member of the drop speed control screw rod 23 is provided with drop velocity modulation section spiro rod cap 24.It is easy to rotate drop velocity modulation section
Screw rod.
Preferably, the titration regulation fixed mount is provided with the fast table 25 of drop, and the fast table 25 of drop is provided with centre bore, the drop speed
Control screw rod 23 is provided with the fast graduation mark of drop, the drop velocity modulation section through the centre bore for dripping fast table 25, the drop speed table 25
Spiro rod cap 24 is provided with the drop speed instruction line corresponding with the fast graduation mark of drop.
Preferably, 1/2 girth with diameter greater than the flexible pipe 22 of the fast adjusting screw rod 23 of the drop.
The operating method of titration outfit of the present invention is as follows：
Before titration, drop velocity modulation section spiro rod cap is rotated clockwise, the drop speed adjusting screw rod 23 on drop velocity modulation section fixed mount 21 exists
Rotated in screwed hole, the fast front end of adjusting screw rod 23 of drop is constantly moved ahead, and squeezing tube 22, the upper end of flexible pipe 22 is connected under buret 1
The liquid outlet at end.The lower section of flexible pipe 22 is correspondingly provided with the container 4 for being contained with sample to be titrated, and container 4 is placed on electronic scale 5.Drop velocity modulation
Section screw rod 23 pushes flexible pipe 22 to opposite with the binding face of flexible pipe, and flexible pipe is gradually extruded into flat, and pipe void reduces, and drips velocity modulation
Fast instruction line is dripped on section spiro rod cap 24 to be rotated as screw rod is rotated, and extremely drips 0 scale that fast instruction line points to drop speed table.Toward titration
Titrant is added in pipe 1, such as liquid level concave surface exceeds zero graduation line, counterclockwise slow to rotate drop velocity modulation section spiro rod cap 24, drop
Fast adjusting screw rod 23 is moved backward, and flexible pipe 3 is gradually released a bit, and titrant is oozed, by the regulation of liquid level concave surface to zero graduation line,
Drop velocity modulation section spiro rod cap 24 is rotated clockwise immediately, to 0 scale for dripping the fast fast table of instruction line sensing drop.Liquid to be titrated is put to titration
Under Guan Suolian flexible pipes, rotate in an anti-clockwise direction drop velocity modulation section spiro rod cap 24, the fast adjusting screw rod 23 of drop is moved backward, flexible pipe gradually by
Unclamp, the increase of flexible pipe internal pore, titrant flow velocity increase in flexible pipe, according to the fast instruction line correspondence of drop on drop velocity modulation section spiro rod cap 24
Fast scale is dripped on the fast table of drop and selects suitable speed titration.Nearly terminal when, rotate clockwise the fast adjusting screw rod 23 of drop, drip velocity modulation
The section continuous squeezing tube of screw rod 23, titrant flow velocity reduces in flexible pipe, and according to the fast table high scale of drop, rotary screw cap makes drop speed
Instruction line is directed at the neighbouring graduation mark of 0 scale and is titrated, and titrating solution is titrated with relatively slow drop speed, if desired for slower drop speed, can
The drop speed instruction line that velocity modulation section spiro rod cap 24 will be dripped is rotated to 0 graduation mark, drop speed slow easier grasp terminal opportunity, it is ensured that titration is accurate
Really reach home.
