Abstract
The utility model relates to a needle tubing type sampler. The needle tubing type sampler comprises a needle tubing (1), a plug valve (2), a cylinder tube (3), a seal ring (4), a piston (5) and a central lever (6), and is characterized in that the needle tubing (1) of the needle tubing type sampler is in threaded connection with one end of the plug valve (2), the other end of the plug valve (2) is in threaded connection with the cylinder tube (3), the piston (5) is arranged in the cylinder tube (3), and the T-shaped central lever (6) is connected with the piston (5) after penetrating through a central hole in the top of the cylinder tube (3). The needle tubing type sampler is novel in design, convenient to operate, capable of achieving non-leakage emptying-free sampling, safe, healthy and environment-friendly, and capable of avoiding oil gas damage, saving energy resources, preventing hydrogen sulfide-containing toxic gases from polluting the environment pollution and poisoning an operator, and lightening the labor intensity of on-duty workers.
Description
Technical field
The utility model relates to a kind of hand sampling utensil of petrochemical industry, specifically a kind of needle tube type sampler.
Background technology
, at petrochemical industry,, as the supervision measure to production run, regularly emit a small amount of product and detect test for laboratory on pipeline, to grasp real-time production data and product quality.Wherein emit a small amount of product and be called sampling on pressure piping.On existing sampling method, gas and liquid are all taked directly to open the valve discharging, in discharge process, can cause product to reveal, sampling is on-the-spot must prepare additional measures.Such as getting its water cut of oil in test of crude,, according to related request, at first want liquid storage in emptying sampling line, then just the instrument such as available measuring cup is contained and is drawn oil sample, and the oil product of drippage after previous emptying oil product and sampling finish all enters on-the-spot oil tray or other containers of connecing.Rock gas is taken a sample (as chemically examining hydrogen sulfide content etc.), need to open sample valve emptying enough time, then just can extract the rock gas sample under exhaust condition, at this moment having a small amount of gas flies away in atmosphere, not only waste energy, contaminated environment, and it is healthy directly to endanger the sampling personnel.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, has designed a kind of needle tube type sampler.
The utility model comprises: needle tubing, stopcock, cylinder barrel, O-ring seal, piston, center-pole.The needle tubing of its needle tube type sampler is connected with the threaded one end of stopcock, and the other end of stopcock is threaded with cylinder barrel, is provided with piston in cylinder barrel, and the center pit that " T " center-pole passes the cylinder barrel top connects with piston.
Piston in above-mentioned needle tube type sampler is circumferentially with O-ring seal.
Stopcock in above-mentioned needle tube type sampler is the angie type stopcock.Needle tubing top in above-mentioned needle tube type sampler is cone, and upper end is provided with external thread, and bottom is arranged with liquid flow hole, and bottom is round end.
The beneficial effects of the utility model are: modern design, easy to operate, can accomplish to exempt from emptying sampling without leaking, safety, healthy, environmental protection, avoid oil gas to damage, energy savings, prevent that the leak environmental pollution and the operating personnel that cause of the toxic gases such as sulfide hydrogen are poisoning, alleviates post workman's labour intensity.
Description of drawings
Fig. 1-the utility model master looks the complete section structural representation.
In accompanying drawing, 1. needle tubing, 2. stopcock, 3. cylinder barrel, 4. O-ring seal, 5. piston, 6. center-pole; A. liquid flow hole.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
The needle tube type sampler is comprised of needle tubing 1, stopcock 2, cylinder barrel 3, O-ring seal 4, piston 5, center-pole 6.The needle tubing 1 of its needle tube type sampler is connected with the threaded one end of stopcock 2, and the other end of stopcock 2 is threaded with cylinder barrel 3, is provided with piston 5 in cylinder barrel 3, and the center pit that " T " center-pole 6 passes cylinder barrel 3 tops connects with piston 5.
Method of operating
At first, while getting liquid with certain pressure, gas sample, cut-out tap valve 2, open sample valve, needle tubing is inserted the rubber plug that is threaded with the sample valve outlet and penetrates, when needle tubing enters into the pipeline middle part, put liquid container well, open stopcock 2, in pipeline, liquid flows along needle tubing 1, enter sampling container through stopcock 2, obtain cut-out tap valve 2 after suitable volumes liquid, extract needle tubing 1 out and get final product.
Secondly, when the excessively slow liquid of pressure power deficiency or flow velocity, gas sample, can pull piston 5 at the interior generation negative pressure extracting of cylinder barrel 3 sample, during sampling according to piston 5 strokes, while obtaining required sample, close the sampler valve and extract needle tubing 1 out,, due to elastic reaction sealing immediately after needle tubing 1 withdraws from of rubber plug, avoid revealing.When chemically examining operation, open stopcock 2, pushing piston 5, the interior liquid of cylinder barrel 3 or gas enter assay apparatus through needle tubing 1.
Claims (4)
