Abstract
The utility model aims at providing a novel precise micro burette. The novel precise micro burette comprises a liquid adding funnel, wherein the liquid adding funnel is connected with a conduit; a filter layer is arranged on the conduit; a pressure-regulating valve arranged on the conduit is further connected and mixed with a liquid storage unit; the lower end of the conduit is connected with a burette by a fluid director; and a V-shaped liquid adding tank is arranged on the burette. The novel precise micro burette disclosed by the utility model has the beneficial effects that operation is simple and convenient, experiment can be precisely measured and analyzed in a micro manner, cost is low, functions are complete, liquid can be added in both directions at the same time for controlling the measurement according to needs, and working efficiency is effectively improved; automatic control can be realized by the arranged pressure-regulating valve, so that errors caused by human factors are reduced, titration precision is improved, liquid volume and flow rate can be effectively set, and titration accuracy and precision of the liquid can be improved.
Description
Technical field
The utility model relates to volumetry mensuration field, the specifically a kind of long-pending novel precise plan weighing buret of liquid of measuring that is applied to medical treatment, chemical industry measurement analysis room.
Background technology
Be applied at present in the sky amount test analyzer in industrial and mining enterprises, universities and colleges and laboratory, in traditional measurement, use common buret always, although simple in structure, chemicals consumption is larger higher with cost, manual control many factors, reduced precision, there is error in the air pressure factor particularly existing in existing buret, cause measuring accuracy to reduce when precision measurement, need to be improved to overcome above-mentioned deficiency to prior art.
Utility model content
The utility model object is to provide a kind of Novel precision micro-burette, makes it improve the accuracy of precision measurement, reduces bubble in buret and accelerates the present situation of flow velocity.
In order to realize the utility model object, by the following technical solutions: comprise addition funnel, described addition funnel is connected with conduit, and filtering layer is set on conduit, on conduit, also pressure regulator valve is set and reservoir is connected and fixed; In conduit lower end, by air deflector, be connected with buret, V-type be set on buret and add flow container.
Further, set out balloon valve and air inlet ball valve on described pressure regulator valve, measured value that can randomly regulating conduit internal gas pressure, with more accurate precision of measurement.
Between described air deflector and buret, be 55 degree angles and install, effectively improve in prior art, because buret 90 degree connect, the present situation that produces bubble is set, to accelerate flow velocity, avoid the situation of stopping up, saved the time.
The beneficial effects of the utility model are: easy and simple to handle, accurately experiment is analyzed in microdetermination, and cost is low holds concurrently, multiple functional, can two-wayly as required with entering liquid feeding control, measure, and effectively increase work efficiency; The pressure regulator valve that Yin Ben device arranges, can realize automatic control, reduces the error that human factor causes, improves the precision of titration, and liquid volume and flow velocity can be set easily and effectively, improves the veracity and precision of liquid titration.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further elaborated: comprise graduated tube, addition funnel, described addition funnel is connected with conduit 2, and filtering layer 3 is set on conduit 2, pressure regulator valve 5 is also set on conduit 2 and is connected and fixed with reservoir 6; In conduit 2 lower ends, be connected by air deflector 9 with buret 8, on buret, 8 arrange V-type and add flow container 7.On described pressure regulator valve 5, set out balloon valve 10 and air inlet ball valve 11.Between described air deflector and buret, being 55 degree angles installs.During operation is used: liquid enters the interior inflow through filtering layer 3 of conduit 2, and waste liquid is kept somewhere, air pressure is through give vent to anger ball valve or the air inlet ball valve adjustment manifold pressure value of pressure regulator valve setting.In figure, between air deflector and buret, be 55 degree angles and install, further improve flow velocity and the volume size of drop, have and change the measured value that reduces personal error operation.The utility model does not describe part in detail and is known technology, and the common variation that those skilled in the art carries out within the scope of technical solutions of the utility model or replacement all should be included in protection domain of the present utility model.
