Abstract
The utility model discloses a liquid sampler, which is in a shape of a metal cylinder with even diameter. A movable sealing sheet and an oil discharging valve are arranged on the lower portion of the cylinder. The liquid sampler effectively resolves the problem that liquid is not even to sample.
Description
Technical field
The utility model relates to a kind of Liquid sampler.
Background technology
At petrochemical industry, the sampling of fluid product is an important ring of analytical procedure.Sample owing to the difference of density, changes with liquid height in storage process, and its density has gradient difference, and present sample mode has two kinds, and the one, oil drum is stirred the mixing sampling, the representativeness of the time of stirring, influential effect sampling; The 2nd, by dipstick and sample can,, to mix again three differing heights samplings, this mode is a grab sampling, and representativeness is not strong, and error is bigger, and operation is also inconvenient.
CN200820158068.2 discloses a kind of new liquid sampling thief; Comprise support frame and on sampling pipe; Said sampling pipe comprises sampling long tube and sampling bend pipe, on skeleton, is communicated with sampling long tube, spherical valve, wobble pump, spherical valve and sampling bend pipe successively.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.
Summary of the invention
To the deficiency of 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.
The utility model Liquid sampler structure is following: Liquid sampler be shaped as the uniformly straight tube of diameter, the diaphragm seal that straight tube bottom setting and straight tube bottom flexibly connect, a straight tube cylindrical shell bottom is provided with fuel outlet valve.
In the utility model, the general straight tube of corrosion resistant metal that adopts of straight tube.The internal volume of the straight tube of Liquid sampler metal is about 1L ~ 5L, is preferably 1L ~ 2L.The straight tube of metal diameter is 20mm ~ 80mm, is preferably 30mm ~ 50mm.The straight tube of metal is 800mm ~ 1700mm highly, is preferably 1200mm ~ 1500mm.The upper end of straight tube can be open design, also can be for cover plate be set, but on the cover plate air hole need be set.Straight tube top also can be provided with suitable handle, so that use.
The diaphragm seal that flexibly connects with straight tube bottom that straight tube bottom is provided with; One end of diaphragm seal is connected straight tube bottom by turning axle; The other end is provided with tension rope; The tension rope upper end is arranged on the upper end of sampling thief cylindrical shell, and the upper end can be provided with suitable fixed sturcture, is fixed on the appropriate location when being convenient to the tension rope tension.The optional position of tension rope can be provided with spring, forms the suitable tight power that connects when easy to use.Diaphragm seal is provided with suitable O-ring seal with straight tube bottom position contacting.
A kind of Liquid sampler of the utility model design; This sampling thief can be realized uniform sampling under the situation of disturbed sample not; The sample of gathering can the actual response sample character; Reduced analytical error, eliminated sample because the difference that the density gradient difference causes has broad application prospects.
Description of drawings
Fig. 1 is the Liquid sampler structural representation;
Wherein: 1, the straight tube of sampling thief metal, 2, fuel outlet valve, 3, diaphragm seal, 4, tension rope.
Embodiment
As shown in Figure 1, the utility model Liquid sampler be shaped as the uniformly straight tube 1 of diameter, the diaphragm seal 3 that straight tube bottom setting and straight tube bottom flexibly connect, a straight tube cylindrical shell bottom is provided with fuel outlet valve 2.Diaphragm seal 3 carries out opening and closing through tension rope 4.
The utility model sampling thief method of application is following:
(1) close fuel outlet valve 2, unclamp tension rope 4, make diaphragm seal 3 be releasing orientation fully, at this moment, diaphragm seal 3 is the vertical hanging state;
(2) vertical slowly being inserted in the liquid container of straight tube, be inserted at the end fully, sample is the full-height sample in the container in the tube of this moment;
(3) upwards strain stay cord 4, straight tube bottom end seal;
(4) propose sampling thief, clean the outside, open fuel outlet valve 2, put into ready small container to sampling, sampling is accomplished in sealing.
