Abstract
The utility model discloses a liquid sampler which takes the shape of a straight barrel with uniform diameters, wherein an annular platform is arranged at the bottom end of the straight barrel body; a sealing sheet which is movably connected with the annular platform is arranged on the annular platform; a material holding rod which is connected with the sealing sheet is arranged on the lower surface of the sealing sheet; an air inlet tube is arranged at the upper end of the straight barrel; and a valve is arranged on the air inlet tube. The liquid sampler provided by the utility model is convenient to operate, realizes full-height sampling, is strong in sample representativeness and reduces analysis errors.
Description
Technical field
The utility model relates to a kind of Liquid sampler.
Background technology
At petrochemical industry, the analysis of sample at first needs sampling, and therefore, sampling is an important ring of analytical procedure.Fluid sample is in storage process, and with the variation of liquid height, its density has gradient disparities.Present sampling mode has two kinds, and the one, stir again sampling after fluid sample is mixed, the representativeness of the time of stirring, influential effect sampling; The 2nd, by the instruments such as dipstick in upper, middle and lower three differing heights get the sample of aliquot, then three duplicate samples are mixed again, this mode is grab sampling, the average sample of obtaining lacks public credibility, representativeness is not strong, error is larger, operation is also inconvenient.
CN200820158068.2 discloses a kind of Novel liquid sampler, comprise support frame and on sampling pipe, sampling pipe comprises sampling long tube and sampling bend pipe, is communicated with successively sampling long tube, spherical valve, wobble pump, spherical valve and sampling bend pipe on skeleton.When can solving sampling, this Liquid sampler exist air to cause and to sample in the pipe, the blocking pipe problem that container bottom exists sediment to cause.But do not solve the not representative and problems such as analytical error brought of above-mentioned sampling, its structure is also comparatively complicated.
CN202066718U discloses a kind of sampling device for tank car, comprises stopple coupon, hand valve, stay cord, and stopple coupon one end is provided with the hand valve, and bolt has stay cord on the hand valve handle, and during hand valve opening, hand valve handle is horizontal position.This sampler has solved the representative and problem of the analytical error brought of sampling, but structure is still complicated.
CN202182832U discloses a kind of Liquid sampler, be shaped as the uniform straight tube of diameter, the straight tube bottom arranges the diaphragm seal that is flexibly connected with the straight tube bottom, one end of diaphragm seal is connected to the straight tube bottom by turning axle, the other end arranges tension rope, the tension rope upper end is arranged on the upper end of sampling thief cylindrical shell, and straight tube cylindrical shell bottom arranges fuel outlet valve.This Liquid sampler has solved the representative and problem of the analytical error brought of sampling, but structure is still complicated.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of Liquid sampler, and is easy to operate, particularly realized the full-height sampling, and sample representativeness is strong, has reduced analytical error.
This practicality provides a kind of Novel liquid sampler, described Liquid sampler structure is as follows: Liquid sampler be shaped as the uniform straight tube of diameter, straight tube cylindrical shell bottom is provided with the ring platform, arrange and encircle the diaphragm seal that platform is flexibly connected on the described ring platform, the lower surface of described diaphragm seal is provided with the blowing bar that is connected with diaphragm seal, the straight tube upper end is provided with draft tube, be provided with valve on the draft tube, described valve can be a kind of in ball valve, needle-valve, stop valve, gate valve, diaphragm valve, stopcock, butterfly valve, plunger valve, the bulb stopper valve, preferred ball valve.
In the utility model, the corrosion resistant metal cylinder of the general employing of straight tube cylindrical shell.The internal volume of Liquid sampler metal straight tube is about 1～5L, is preferably 1～2L.The diameter of metal straight tube is 20～80mm, is preferably 30
～50mm。Metal straight tube height is 800～2000mm, is preferably 1000～1600mm.The width of described ring platform is 5%～45% of straight tube diameter.Straight tube top also can arrange suitable handle, so that use.
In the utility model, an end of described diaphragm seal is connected on the ring platform by turning axle, and diaphragm seal arranges suitable O-ring seal with the position that the ring platform contacts.
Liquid sampler described in the utility model, simple in structure, easy to use, this sampling thief can be realized uniform sampling in the situation of disturbed sample not, the sample that gathers can the actual response sample character, reduce analytical error, eliminated sample because the difference that the density gradient difference causes has broad application prospects.
Description of drawings
Fig. 1 is the utility model Liquid sampler structural representation.
Embodiment
Below in conjunction with accompanying drawing Liquid sampler described in the utility model is described further.
Shown in Fig. 1, the utility model Liquid sampler be shaped as the uniform straight tube 1 of diameter, the straight tube bottom arranges ring platform 2, the diaphragm seal 3 that ring platform 2 upsides hinged one and ring platform 2 are flexibly connected, the bottom of diaphragm seal 3 connects a blowing bar 4, the upper end of straight tube 1 is provided with draft tube 5, and a ball valve 6 is set on the draft tube 5.
The utility model sampling thief using method is as follows:
(1) opens ball valve 6, straight tube vertically is inserted in the liquid container slowly, and diaphragm seal 3 is opened automatically in the process of inserting, and the gas in the straight tube is discharged from ball valve 6 simultaneously, when straight tube was inserted in the container fully, sample was the full-height sample in the container in the cylinder of this moment;
(2) close ball valve 6, propose sampling thief, straight tube sealed bottom sheet 3 in mentioning process owing to closed by the pressure of sample;
(3) when blowing bar 4 contacted with the small container of collecting sample, diaphragm seal 3 was opened, and opens simultaneously ball valve 6, and the liquid in the sampling thief just can flow in the small container, behind the sealed sample, finishes sampling.
