Abstract
The invention discloses a liquid and solid-liquid mixed sampler. The sampler is characterized in that the sampler is of a split structure, and comprises a pull rod, a barrel, a barrel end cover, a movable sleeve, a sealing ring and a replacement valve, wherein the lower end of the pull rod is connected to the sealing ring; the sealing ring is fixedly arranged at the lower end of the pull rod through a gasket and a screw, and is matched with the inner surface of the barrel; the lower end of the barrel is connected with the barrel end cover through a screw; the replacement valve is fixedly arranged on the barrel end cover; the movable sleeve is detachably connected to a pipe at the lower end of the barrel end cover. According to the liquid and solid-liquid mixed sampler, measured required substance content is required, misguide to production is avoided, and unnecessary economic loss can be avoided.
Description
The application is a divisional application, and original applying number is 201110438819.2, and original application day is on Dec 23rd, 2011, and former denomination of invention is " a kind of liquid and solid-liquid mixture sampler and sampling method ".
Technical field
The present invention relates to a kind of liquid and solid-liquid mixture sampler and sampling method, belong to the measuring apparatus and metering method that ensure safety in production.
Technical background
In the prior art, the sampler of liquid and solid-liquid mixture can only get surface sample, sample at all levels under can not getting liquid level, such as, in solidliquid mixture bottom sample, get beneath solid when forming vicissitudinous liquid, solid and liquid stratification, particularly, the sample at all levels in dark pond, large tank can not be got.Therefore, measure the desired substance content out of true come, often can mislead production, thus cause unnecessary economic loss.
CN201561883U relates to the sampler preventing sample gas from revealing, and for this reason, it must be overall that cylindrical shell imports and exports one end at sample, can not be dismountable structure.
The displacement valve of CN201378111Y at the tip of stopple coupon, inconvenient operation during sampling; And scale is on piston cylinder, in sampling operation process cannot directly, can go out to insert the degree of depth of mixing material intuitively.
The transparency protected urceolus of PC of CN201378111Y is also necessary, and 0-50 milliliter gas volume groove and 0-100 gas second push away fast groove and must be arranged on (scale, only for gas, is not used in liquid, is not used in potpourri) on sampling glass tube; Require fast sampling (thermometer and timer assembly must be provided with); Can be used for gas sampling, also can be used for liquid sample (not relating to the sampling of biased sample); Skull is fitted in the end of protection urceolus, skull can not to be become " detachably ", otherwise, just no longer there is the function of gas sampling! Nor 0-50 milliliter gas volume groove and 0-100 gas second may be pushed away fast groove and be arranged on the pipe at conversion threeway place, otherwise the effect of thermometer and timer assembly just loses, and the goal of the invention of " convenient operation " also just can not achieve.
JP5 Showa 7-97256U and CN201527368U sampling pipe with a scale is not sleeve pipe, but is fixedly connected on piston cylinder.
What CN2496009Y adopted is " the commercially available medical needle tubing that draws water ", this means that its barrel body end cover and cylindrical shell are the structures of one
The prejudice of conventional art is, barrel body end cover and cylindrical shell are all " one-piece constructions "!
Prior art all can only get the sample on surface, can not pump the following degree of depth of liquid level greatly, the sample of even bottom.Combination between prior art all can not obtain dismountable sampling " sleeve pipe ", is not easy to carry.And cannot unpick and wash after blocking, cause sampler to be cancelled, very uneconomical.
Any combination between prior art all can not obtain all detachable, the portable sampler in each position of the present invention.After blocking, links can be convenient for dismounting and washing, and sampler can not be caused to cancel.
In addition, only have the top scale on sleeve pipe of the present invention to be 0, the degree of depth inserting sampling medium is very clear on sleeve pipe.
Instant invention overcomes traditional technology prejudice, barrel body end cover so that the lower end of cylindrical shell can be connected to mode for convenience detach so that safeguard, cleaning or maintenance! Therefore, in sampler of the present invention, barrel body end cover and cylindrical shell are " Split type structures ".
Summary of the invention
The object of this invention is to provide a kind of liquid and solid-liquid mixture sampler and sampling method, it is accurate that it measures the desired substance content come, and can not mislead production, can avoid unnecessary economic loss.
For this reason, according to a first aspect of the invention, provide a kind of liquid and solid-liquid mixture sampler, it is characterized in that, comprise pull bar, cylindrical shell, barrel body end cover, moving casing, sealing ring and displacement valve; The lower end of described pull bar is connected on described sealing ring, and described sealing ring is fixed on the lower end of described pull bar by pad and screw; Described sealing ring matches with the inside surface of described cylindrical shell; The lower end of described cylindrical shell is connected with described barrel body end cover by screw thread; Described displacement valve is fixed in described barrel body end cover; Described moving casing is removably connected on the pipe of described barrel body end cover lower end.
