Description
[technical field]
The utility model relates to a kind of sampling systems, more particularly, to a kind of isothermal and isobaric continuous sampling system.
[background technique]
Whether the crucial method for being to sample and sample are representative whether pipeline transporting oil accurate measurement.It is logical at present
Technology is: indicating have medium flowing in pipeline when pressure sensor has value when medium inlet, the signal that it will test
It is uploaded to PLC；Medium temperature signal is also uploaded to PLC by the temperature sensor on the pipeline of medium inlet simultaneously；In PLC
The signal and initial setting value that CPU will test are compared, if pressure, temperature reach setting value, PLC will provide output
Electronic positive rotaring signal is controlled, motor starts to rotate forward, and the medium of pipeline starts due to the effect of electric gear wheel pump in sample bypass stream
It is dynamic to enter Trunk Line by filter；It powers to setting time PLC to solenoid valve, medium enters fixed volume tank by threeway,
Medium in fixed volume tank is pressed into sampling bottle under the pressure of the spring, terminates primary sampling.Hereafter by the frequency week of design
Phase work, until the amount of sampling reaches scheduled amount, signal is uploaded to PLC by weighing sensor, and it is all that PLC closes motor cutting
Control, starts above-mentioned circulation by start button until next time.Due to medium be directly be driven into sampling bottle utensil, so by
In ambient temperature and it will cause light component with pipeline pressure difference and can be lost, heavy constituent, which can go bad, etc. influences sample effect
Drawback.
[summary of the invention]
In order to overcome the shortcomings in the background art, the utility model discloses a kind of isothermal and isobaric continuous sampling system, passes through
The cooperation of piston cylinder and batcher, realizing will need the medium sampled to be stored in piston cylinder, ensure that the sample in piston cylinder
Medium isothermal and isobaric in product and pipeline and the purpose that continuous sampling can be carried out.
In order to realize the goal of the invention, the utility model adopts the following technical solution:
A kind of isothermal and isobaric continuous sampling system, including it is sample gas outlet, piston cylinder, sample gas inlet, circulating pump, quantitative
The input terminal of device and sample outlet, circulating pump connects sample gas inlet, and the output end of circulating pump is separately connected the input of batcher
It holds, one end of sample gas outlet and piston cylinder, sample outlet is separately connected the output end of batcher and the other end of piston cylinder,
