Description
Technical field
The utility model relates to laboratory dispensing device, is specially a kind of metering sampler.
Background technology
Chemistry and Bioexperiment often need to take out a certain amount of solvent from the container of sealing. The instrument of prior art many employings graduated cylinder one class takes out liquid from container and measures liquid. This process all exposes in atmosphere, and adopts the mode toppled over to get liquid, not only easily makes solvent by the foreign substance pollution in air, measures also inaccurate simultaneously.
Practical novel content
The utility model easily makes solvent contaminated to solve the existing mode quantitatively measured, it is intended to sampler not easily contaminated when providing a kind of solvent to measure.
The utility model offer base case is: metering sampler, comprise solvent barrel, wherein, also comprising Chou Ye mechanism and metering mechanism, described Chou Ye mechanism comprises pumping cylinder, the first check valve, the 2nd check valve and takes out liquid inlet pipe, described in take out that the bottom of solvent barrel is stretched in liquid inlet pipe one end, the other end is connected the first check valve, described first check valve is connected pumping cylinder, described pumping cylinder is connected the 2nd check valve, slidably connects piston in described pumping cylinder, and the piston rod of described piston stretches out pumping cylinder; Described metering mechanism comprises recorder jar and communicating pipe, and one end connection of described communicating pipe the 2nd check valve, the other end are connected recorder jar, and the sidewall of described recorder jar is provided with metering scale, and the bottom of described recorder jar is connected with liquid-outlet valve.
Principle of work: during sampling, pull piston rod, in pumping cylinder, air pressure diminishes, air pressure in solvent barrel by the solvent in bucket by taking out liquid inlet pipe, first check valve pushes away into pumping cylinder, promote piston rod, piston extruding solvent, now the first check valve now closes, solvent is through the 2nd check valve, communicating pipe enters recorder jar, operator while repeat appeal operation, while observing the height of the liquid level of the solvent in recorder jar and contrasting with metering scale, when the amount of the solvent in recorder jar arrives sampling value, stop the operation to piston, open liquid-outlet valve and just take out quantitative solvent.
Compared with prior art, the advantage of this scheme is: before opening liquid-outlet valve, in this scheme, solvent does not all have the container with outside and air contact, ensure that solvent is not quantitatively contaminated, first than the instrument manual operation adopting graduated cylinder one class in prior art, the contaminated possibility of solvent greatly reduces, and adopts piston rod as power mechanism simultaneously, can directly push-and-pull can complete to extract work, easy to operate and accurate.
Scheme two: based on scheme preferred, described metering mechanism also comprises siphon pipe, and described siphon pipe one end stretches into recorder jar and bottle cap with recorder jar is slidably connected, and the described siphon pipe the other end stretches into the bottom of solvent barrel. Useful effect: this scheme controls the amount measured by piston, but drip from promotion piston to solvent and recorder jar needs certain delay, so the solvent in recorder jar has when exceeding unavoidably, siphon pipe is set, by the scale of the lower end aligned recorder jar of siphon pipe, owing to solvent can make the pressure in bottle higher than the pressure of solvent barrel after entering recorder jar, exceed the solvent that scale contacts with siphon pipe in recorder jar and can be inhaled in solvent barrel.
Scheme three: preferred for scheme two, described recorder jar is also connected with vapor pipe, and described vapor pipe is provided with vent valve. Useful effect: but in recorder jar gas pressure intensity exceed external pressure too many time, it is necessary to open vent valve.
Scheme four: preferred for scheme three, the end of described piston rod is provided with handle. Useful effect: handle handled easily human users's piston is set.
Scheme five: preferred for scheme four, the bottle cap of described recorder jar is provided with sealing-ring, outside described sealing-ring is sheathed on siphon pipe. Useful effect: described siphon pipe to be slided with bottle cap, so the junction sealing of the two is easily gone wrong, arranges the stopping property that sealing-ring strengthens the two junction.
Scheme six: preferred for scheme five, recorder jar is fixedly connected with solvent barrel. Useful effect: recorder jar is glasswork, be placed on solvent logical on, knock over just easily broken during operation because of carelessness, be fixed in solvent logical on avoid damaging.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model metering sampler embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: solvent barrel 1, pumping cylinder 2, first check valve 41, the 2nd check valve 42, take out liquid inlet pipe 51, recorder jar 3, communicating pipe 52, liquid-outlet valve 31, siphon pipe 53, piston 21, piston rod 221, vapor pipe 6, vent valve 61.
Metering sampler as shown in Figure 1, comprise solvent barrel 1, wherein, also comprise Chou Ye mechanism and metering mechanism, described Chou Ye mechanism comprises pumping cylinder 2, first check valve 41, the 2nd check valve 42 and takes out liquid inlet pipe 51, described take out that the bottom of solvent barrel 1 is stretched in liquid inlet pipe 51 one end, the other end is connected the first check valve 41, described first check valve 41 is connected pumping cylinder 2, described pumping cylinder 2 is connected the 2nd check valve 42, slidably connecting piston 21 in described pumping cylinder 2, piston 21 bar of described piston 21 stretches out pumping cylinder 2; Described metering mechanism comprises recorder jar 3 and communicating pipe 52, and one end connection of described communicating pipe 52 the 2nd check valve 42, the other end are connected recorder jar 3, and the sidewall of described recorder jar 3 is provided with metering scale, and the bottom of described recorder jar 3 is connected with liquid-outlet valve 31.
