Abstract
The invention relates to an anti-theft airtight quick sampling valve, which includes a micro ball valve, a sampling tube and a sampling control tube, and is characterized in that an inlet male thread of the micro ball valve is connected with a female thread of a sampling connector on a sampling pipeline; a female thread thereof is connected with the sampling control tube; an outlet of the micro ball valve is in threaded connection with a pressing cap with a backstop annular groove; an annular rubber seal gasket is arranged between the pressing cap and the outlet of the micro ball valve; the sampling tube passes through the pressing cap, the annular rubber seal gasket and a ball core hole, and is inserted into the sampling control tube. When the anti-theft airtight quick sampling valve is used for sampling, no blind sample region exists, airtight sampling without evacuation can be realized, qualified samples can be sampled, accuracy of sample test analysis data can be ensured, reliable parameters can be provided for development and analysis of oil gas fields, and requirements of formulation of a development scheme of oil gas fields can be met.
Description
Technical field
The present invention relates to a kind of crude oil sampling controlling organization, specifically a kind of antitheft airtight fast-type sample valve.
Background technology
The oil field is to the Physical Property Analysis of crude oil and natural gas, all carries out assay by the gentle sample that draws oil sample at gathering line and gas gathering line and obtains reference data producing dynamic analysis, and obtaining qualified sample is key problem in technology.There are following shortcoming in present sample valve structure and sampling mode to obtaining qualified samples: the one, and emptying sampling, first dead sample in sample valve and the sample connection is bled off, get again the real online fresh sample that flows, this follow the example of not only waste energy, contaminated environment, also destroyed the flow regime of oil gas water, the sample that takes out is gas entirely or is water entirely or is oil entirely, can not reflect online truth.The 2nd, present sample valve structure, certainly exist dead sample in the sample valve and in the sample connection, do not bleed off and just can not guarantee that the sample of getting is fresh fully, it is impossible that the existence of above-mentioned two kinds of shortcomings will obtain very qualified sample, must change sample valve structure and sampling mode.
Summary of the invention
The purpose of this invention is to provide a kind of antitheft airtight fast-type sample valve, overcome the defective that above-mentioned prior art exists.
Technical scheme of the present invention is achieved in the following ways:
The present invention includes micro ball valve, probe tube and sampling control valve, the male thread that it is characterized in that the import of micro ball valve is connected with sample connection box thread on the sampling line, box thread is connected with sampling control valve male thread or the control valve male thread of taking a sample is connected with the sample connection box thread, and the male thread of sample connection is connected with the box thread of micro ball valve; The outlet of micro ball valve is threaded with the pressure cap that is provided with the retaining cannelure, is provided with the ring-shaped rubber sealing mat between pressure cap and micro ball valve outlet; Probe tube passes the pressure cap ring-shaped rubber pad and ball core hole is inserted in the sampling control valve.
Sampling control valve one end is provided with male thread, and the other end is provided with blind plate, and the middle part is provided with ball seat, and ball seat is provided with ball sealer, is provided with sample holes in the ball seat upper periphery, is provided with helical spring at ball sealer between the blind plate, and week is provided with rubber seal in the middle and lower part.
Probe tube one end is provided with the enclosed sampling joint of male thread or box thread and sampling control valve, and other end periphery is provided with injection port, and the probe tube periphery is arranged with two retaining posts in sampling control valve front.
Pressure cap one end internal diameter is large, and other end internal diameter is little, and what internal diameter was large is provided with box thread in interior week, and internal diameter is little is provided with the retaining cannelure interior week, and retaining cannelure to external port is arranged with two and enters notch, and periphery is provided with the spanner rib.
The present invention takes a sample without dead sample district, can realize not emptying enclosed sampling, can guarantee to get qualified samples, can guarantee the accuracy of sample laboratory analysis of data, analyzes to the exploitation of oil gas sky reliable parameter is provided, and satisfies the requirement of formulating the oil-gas field development scheme.

The specific embodiment
For further disclosing technical scheme of the present invention, elaborate by embodiment below in conjunction with Figure of description:
The present invention includes micro ball valve 3, probe tube 1 and sampling control valve 9, the male thread that it is characterized in that the import 4 of micro ball valve 3 is connected with sample connection box thread on the sampling line, box thread is connected with sampling control valve male thread or the control valve male thread of taking a sample is connected with the sample connection box thread, and the male thread of sample connection is connected with the box thread of micro ball valve; The outlet of micro ball valve 3 is threaded with the pressure cap 2 that is provided with the retaining cannelure, is provided with the ring-shaped rubber sealing mat between pressure cap 2 and micro ball valve 3 outlets; Probe tube passes the pressure cap ring-shaped rubber pad and ball core hole is inserted in the sampling control valve.
Sampling control valve 9 one ends are provided with male thread, and the other end is provided with blind plate, and the middle part is provided with ball seat 6, ball seat 6 is provided with ball sealer 7, be provided with sample holes 5 in ball seat 6 upper periphery, to being provided with helical spring 8 between the blind plate, week is provided with rubber seal in the middle and lower part at ball sealer 7.
Probe tube 1 one ends are provided with the enclosed sampling joint of male thread or box thread and sampling control valve, and other end periphery is provided with injection port, and the probe tube periphery is arranged with two retaining posts in sampling control valve front.
Pressure cap 2 one end internal diameters are large, and other end internal diameter is little, and what internal diameter was large is provided with box thread in interior week, and internal diameter is little is provided with the retaining cannelure interior week, and retaining cannelure to external port is arranged with two and enters notch, and periphery is provided with the spanner rib.
The present invention is in application process, and micro ball valve 3 is mounted on the sample connection of sampling line, and it is motionless that sampling control valve 9 is installed in micro ball valve 3 imports 4.Probe tube 1 be with oneself with, close when micro ball valve 3 is flat, when sampling, probe tube 1 and sealing sampler are connected carry-on being with, to micro ball valve 3 places, micro ball valve 3 is opened, this moment ball sealer 7 in pipe pressure and the effect of helical spring 8 under tight with ball seat 6 sealings, the interior sampled medium of pipe does not flow out.After opening micro ball valve 3, probe tube 1 is injected, slowly push away forward, ball sealer 7 is opened in fast front ejection when pushing up to ball sealer 7, instantaneous retaining post on the probe tube is advanced the retaining cannelure from entering notch, a retaining post that rotates to an angle blocks, probe tube 1 can not got by sampled overpressure, slowly open the sampling control valve on the probe tube, sample will slowly flow in the sealing sampler, can not produce large impact to sample, sampling is complete when the pressure of sealing sampler and the pressure balance in the sampled pipe.
