Abstract
The utility model relates to a burette glass head for element analyzer comprising a drip tube and a siphon tube. The drip tube is provided with a dispenser tube. The device is characterized in that the upper end of the dispenser nozzle of the drip tube is added with a buffer tube and a liquid-holding tube. The tube body between the buffer tube and the liquid-holding tube is provided with floating balls. When the liquid inside the drip tube rises to the tube body between the buffer tube and the liquid-holding tube, the floating balls rise with the liquid and clog the channel that goes into the held liquid from the buffer body. The utility model has the advantages of simple structure, easy and convenient use and realizes the control of liquid dispensing without electrodes, thus fundamentally solving the problems that are caused by the electrodes and the control circuits. The device effectively cuts down the malfunction rates of carbon and sulphur analyzers, facilitates the users and reduces the service cost of analyzer suppliers.
Description
Technical field
The utility model relates to a kind of elemental analyser buret.
Background technology
Adopt carbon sulphur high speed analysis instrument to come the content of carbon-sulfure elements in the analysis of metallic materials at present mostly, this type of carbon sulphur high speed analysis instrument adopts the legal carbon of air-capacitor, iodimetric titration is decided sulphur, it is not high to have price, easy to use, the advantage of fast detecting, but use the buret liquid feeding of controlling by electrode owing to decide sulphur, and iodine titration solution has certain corrosivity, cause liquid feeding problems out of control such as electrode normal open after by hydrojet so the electrode plug that causes the malfunctioning and loading electrode of electrode control circuit that is corroded in use often occurs, bring very big inconvenience for analyzer user and instrument supplier.This problem long-term existence, never effective method gives basic solution.
Summary of the invention
To be solved in the utility model is exactly the existing liquid feeding problem out of control of deciding the normal appearance of sulphur buret electrode control liquid feeding of carbon and sulfur analytical instrument that existing employing iodimetric titration is decided sulphur.
The utility model comprises dropper, siphon pipe, top one end that it is characterized in that the filling opening of dropper increases separator tube and liquid storing tube, be provided with ball float in the body between separator tube and the liquid storing tube, when the liquid in the dropper rises in the body between separator tube and the liquid storing tube, thereby ball float can rise with liquid and stops up the passage that leads to liquid storing tube from separator tube.
The utility model is simple in structure, easy to use.It is by increasing separator tube, liquid storing tube, ball float above filling opening, when titrating solution is filled it up with, the ball float blocking channel, liquid can't continue to add, thereby not needing to have realized electrode control liquid feeding, fundamentally solved because the problem that electrode and control circuit thereof cause, can effectively reduce the fault rate of carbon and sulfur analytical instrument, make things convenient for the user, reduce analyzer supplier's cost of serving.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is a fundamental diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model is made of dropper 6, siphon pipe 5, liquid-feeding tube 4, separator tube 3, liquid storing tube 1 and ball float 2.Separator tube 3 and liquid storing tube 1 are all rounded, are located at top one end of the liquid-feeding tube 4 of dropper 6, and the top opening of liquid storing tube 1 communicates with atmosphere.The integral body that dropper 6 and the separator tube 3 that increases and liquid storing tube 1 are integral production when actual fabrication.Be provided with ball float 2 in the body between separator tube 3 and the liquid storing tube 1, when the liquid in the dropper 6 rises in the body between separator tube 3 and the liquid storing tube 1, thereby ball float 2 can rise with liquid and stops up the passage that leads to liquid storing tube 1 from separator tube 3.Siphon pipe 5 is located in the liquid-feeding tube 4, and the one end stretches into dropper 6.Liquid-feeding tube 4 is used for being connected with silica gel tracheae by solenoid control.Dropper 6 can be carved with scale, so that read the milliliter number of titration liquid in case of necessity, its lower end is the liquid outlet 7 that is used to connect titration pipeline 11.
Referring to Fig. 2, operation principle of the present utility model is as follows:
Before the carbon and sulfur analytical instrument analyzing and testing, iodine liquid 12 need be added burets 8 to zero points the place be the nozzle position that siphon pipe 5 is positioned at dropper 6 one ends.Then, pressure size according to low-voltage-powered gas 16, determine that iodine liquid fills it up with dropper 6 required times, adjust the time parameter of control circuit 14 by this time, control magnetic valve 15 (two-position three way) is opened, power gas 16 injects iodine liquid bottle 13 by liquid feeding tracheae 10, and air pressure is pressed into dropper 6 with iodine liquid 12 by liquid-feeding tube 9.After iodine liquid 12 was filled it up with, liquid held up ball float 2 (separator tube 3 plays cushioning effect in this process), and ball float 2 stops up the passage that leads to liquid storing tube 1, and liquid can't continue to add dropper 6.Liquid storing tube 1 is used for storing the iodine liquid 12 that spills when ball float 2 is tight inadequately because of stopping up appears in long-time use.The time of setting when control circuit 14 arrives, and magnetic valve 15 cuts out, do not reinject power gas 16 but by two-position three way magnetic valve 15 logical atmosphere, because the atmospheric pressure effect, the iodine liquid of filling it up with in the dropper 6 12 falls after rise to iodine liquid bottle 13 of iodine liquid bottle 13.When liquid falls after rise to siphon pipe 5 nozzle positions (during zero-bit), siphonage disappears, and liquid no longer falls after rise, and iodine liquid just in time adds to zero-bit, and carbon and sulfur analytical instrument can enter the analyzing and testing state, analyzes titration by exporting the 7 titration pipelines 11 that connect.
By above process, no matter original how much iodine liquid 12 in the buret 8 can guarantee that all the liquid feeding process just in time adds to zero-bit with iodine liquid 12, and no longer need electrode control, fundamentally solved because the problem that electrode and electrode control circuit bring, improved the reliability of carbon and sulfur analytical instrument.
Claims (2)
