The operating principle of extraction type polymer solution sampler of the present invention and existing sampler and analysis:
Existing Wellhead sampler operating principle:
As shown in Figure 3, existing Wellhead sampler, the liquid flowing valve of pipeline valve and sampler is slowly opened successively during sampling, liquid enters sampler cavity under the effect of line pressure, because the pressure reduction in line pressure and sampler is larger, initial stage liquid is in spray regime and enters sampler, along with the increase of amount of liquid in sampler, pressure tends to balance state gradually, then the tapping valve at sampler top is slowly opened, now in sampler, original gas-liquid and the liquid that just entered from pipeline discharge under the effect of the pressure simultaneously, until liquid stream is continuous, till stable, require that drain time is more than 15 minutes, generally discharging liquid measure is during this period 10 ~ 15 liters, the liquid of releasing is by liquid waste processing.Close pipeline valve and liquid flowing valve, open sample valve, the liquid in sampler cavity flows out from sample valve under the effect of liquid level difference, and liquid discharges rear closedown sample valve and tapping valve, terminates sampling.
Find out from the principle of existing Wellhead sampler:
1, in an initial condition owing to being empty in the cavity of sampler, when under the effect at line pressure in the process of opening liquid feed valve, liquid at high speed flows into sampler cavity, and the polymer solution now entered in sampler is seriously sheared;
2, when liquid feed valve and pipeline valve are opened completely, enter the flow velocity of the liquid of sampler mainly by the degree of tapping valve unlatching and the impact of line pressure, the restriction portion of liquid is in the AB section of pipeline and sampler connecting portion, the degree pressure that is larger or pipeline opened when tapping valve is larger, liquid is faster at the flow velocity of AB section, and the mechanical shearing be simultaneously subject to is also more obvious.And the control situation of different operators to tapping valve is also different, the shear rate causing institute's sample thief to be subject to is also variant; When line pressure fluctuates, flow stream velocity also fluctuates thereupon, and this is also that sampling operation personnel are uncontrollable, stops note or cannot sample without during pressure when pipeline.
The operating principle of extraction type polymer solution sampler of the present invention:
As shown in Figure 4, sampler of the present invention vent valve in an initial condition is often opened, liquid feed valve and tapping valve are in closed condition, and in cylinder barrel cavity bottom, namely the soffit of piston and the upper surface of cavity cover for seat are in " dieback " state to piston.After confirming that sampler connects, open the liquid feed valve of pipeline valve and sampler successively, liquid slowly enters the fluid course space of sampler cavity cover for seat under the effect of line pressure, then the tapping valve discharge opeing of sampler is slowly opened, lifting rate equals AB section volume, cavity cover for seat fluid course volume, the twice of discharge opeing tube connector volume summation, general discharge liquid measure 0.3 ~ 0.4 liter, close tapping valve, sampler inside cavity pressure and line pressure are in equilibrium state, rotate handwheel, screw rod and handwheel synchronous axial system, slow jigger lifting piston, low-pressure area is defined by the space that piston is abdicated in cylinder barrel, in pipeline, liquid is inhaled in cylinder barrel gradually by AB section fluid course, the gas of upper piston area is discharged from vent valve, pipeline valve is closed when reaching and estimating sampling amount, pressure now in cylinder barrel is equal with the pressure in pipeline, continuation being carried piston makes the pressure in cylinder barrel reduce, close liquid feed valve, sampler is taken off at connecting short section place between two valves, opening liquid feed valve puts in container by institute's sample thief, sample complete.
Learn from the principle of extraction type polymer solution sampler of the present invention:
1, the flow velocity entering the solution of sampler in sampling process controls by the speed of jigger lifting piston, has nothing to do with the pressure of pipeline, because sampler has swabbing action, even if so pipeline is without pressure or stop note and also can not affect sampling;
2, the flow rate of liquid controlling to enter sampler by slow jigger lifting piston can make liquid more steady at the AB section flow velocity of throttling, effective like this side effect alleviating mechanical shearing and produce solution.
3, in cavity cover for seat, the space of flow channel for liquids is less, the initial stage of drastically reduce the area enters the amount of solution be sheared in cavity, namely decreases the discharge value of waste liquid, saves the time of sampling simultaneously, improve operating efficiency, and decrease liquid waste processing operation and environment pollution.

Analysis of experiments
1, two kinds of samplers on-the-spot polymer solution sample viscosity contrast test data result got under same condition as can be seen from table 1:
Extraction type polymer solution sampler of the present invention than existing sampler get polymer solution viscosity retention ratio all have raising in various degree at every turn, exceed 2.5 ~ 7.3 percentage points.Illustrate that extraction type polymer solution sampler effectively can alleviate the mechanical shearing of polymer solution in sampling process and the viscosity loss caused.
2, learn in two kinds of sampler applicable cases contrasts of table 2:
Adopt extraction type polymer solution sampler than using existing sampler, one is save sample time, and two is the discharge values that drastically reduce the area waste liquid, also eliminates link and the environment pollution of liquid waste processing simultaneously.
3, extraction type polymer solution sampler of the present invention and existing sampler another distinguish and be: discharge the flow velocity of sample when the polymer solution got enters flow velocity and the setting-out of sampler cavity by the impact of pipeline injection pressure.If there is enough liquid in pipeline, even if the liquid in pipeline can be taken out too when pipeline stops note.
