The crude oil quantitative sampling device solves a series of problems of a conventional automatic sampling device and is reasonable in structure, accurate in sampling amount and good in working property.
Description
Technical field
The present invention relates to a kind of crude oil quantitative sampling device.
Background technology
Pipeline crude oil aspect, is typically necessary and is sampled analyzing, and is easy to analyze, draws the quality of output oil.People
The problems such as work sampling is due to cost and sample representation, is gradually replaced by automatic sampling.According to Ju Yuxiang etc.（Ju Yuxiang,
Lian Wen, Lv Chengkui）Introduction, existing pipeline Autosampler main hydraulic piston carries out quantitative sampling to crude oil, but this
Process is limited by the pressure of Hydraulic Station and hydraulic cylinder, and samples sealing ring between cylinder and hydraulic cylinder inside and two cylinder bodies and easily damage
Bad, fault rate is higher.Fu Jian etc.（Fu Jian, Li Hongmei, Wu Xiuli, 2006）Introduce, be utilized respectively electronic measuring scale and carry out quantitation
Sampling, but the error of measuring equipment likely results in the error of sampling, there is certain unstability.
Content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, crude oil quantitative sampling device of favorable working performance.
The technical solution of the present invention is：
A kind of crude oil quantitative sampling device, is characterized in that：Including the sampling probe stretching in crude oil pipeline, sampling probe leads to
Cross pipeloop and be sequentially connected manual ball valve, circulating pump, filter, first check-valve, the first Pneumatic three-way valve, the second non-return
Valve, second check-valve is communicated with crude oil pipeline by pipeloop, the pipeloop between first check-valve and Pneumatic three-way valve
Connect sampling pipeline；Pneumatic ball valve, quantitative pot, the second Pneumatic three-way valve are set gradually on described sampling pipeline, finally connects sample
Product receiving bottle；It is connected by pipeline between first Pneumatic three-way valve and the second Pneumatic three-way valve, setting below sample reception bottle rises
Fall platform.
Crude oil, by sampling probe, sequentially passes through manual ball valve, circulating pump, filter, first check-valve, the first Pneumatic three-way
Valve, second check-valve, eventually pass back to crude oil pipeline, remove the dead oil in exception pipeline；
PLC control system is connected with circulating pump, the first Pneumatic three-way valve, the second Pneumatic three-way valve and pneumatic ball valve, by PLC
Control system is controlled to circulating pump, the first Pneumatic three-way valve, the second Pneumatic three-way valve and pneumatic ball valve；
PLC control system opens the first Pneumatic three-way valve and pneumatic ball valve, and sample is by circulating pump through pneumatic ball valve, the second gas
Dynamic three-way valve, the first Pneumatic three-way valve return to crude oil pipeline, so make the sample in pipeloop with the crude oil of crude oil pipeline be
Synchronous；After PLC control system closing pneumatic ball valve, the first Pneumatic three-way valve, open the second Pneumatic three-way valve, in quantitative pot
Crude oil enters sample reception bottle；PLC control system according to set sampling interval time, automatic Predicated execution continue waiting for when
Between and circulating pump whether stop waiting, next start sampling and adjust preparation for returning to.
The present invention overcomes the series of problems of existing automatic sampling device, rational in infrastructure, and the sampling amount of sampler is accurate,
Favorable working performance.
Brief description
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of one embodiment of the invention.
