Abstract
The utility model discloses a biological membrane sampling device for an oilfield wastewater pipeline in the field of oilfield wastewater detection. The device comprises an upper sleeve, a middle sleeve and a lower sleeve which are coaxially arranged from top to bottom, wherein the upper sleeve and the middle sleeve are connected with each other through a sealing washer; the middle sleeve and the lower sleeve are connected with each other through a ball valve; the lower sleeve is installed on the pipeline; the sampling device runs through the centers of the upper sleeve, the sealing washers, the middle sleeve, the ball valve and the lower sleeve; one end of the sampling device is connected with a pull handle, and the other end of the sampling device extends into the pipeline; and a sampling membrane is arranged on the bottom end of the sampling device. The device is simple in structure, convenient to install and convenient to operate, does not influence the production and safety in a using process and can be used in the oilfield wastewater pipelines for wastewater corroding and scaling condition researches.
Description
Technical field
The utility model relates to a kind of oilfield sewage pipe detection device, particularly a kind of biological membrane sampler.
Background technology
Test at sewage corrosion and scaling situation in the oilfield sewage pipeline in the prior art, generally carry out the test of corrosion and scaling situation or biological membrane is carried out sampling and testing by test piece, do not possess and carry out biological membrane and corrosion product sampled functions simultaneously, this just causes sewage corrosion and scaling situation measuring accuracy lower.
The utility model content
The purpose of this utility model provides a kind of biological membrane sampler that is used for the oilfield sewage pipeline, has solved deficiency of the prior art, and it is simple in structure, and it is convenient, easy to use to install, and has improved sewage corrosion and scaling situation measuring accuracy.
The purpose of this utility model is achieved in that a kind of biological membrane sampler that is used for the oilfield sewage pipeline, comprise the upper bush that from top to bottom is coaxially arranged with, middle sleeve and lower sleeve, link to each other through packing washer between described upper bush and the middle sleeve, link to each other through ball valve between described middle sleeve and the lower sleeve, described lower sleeve is installed on the pipeline, described upper bush, packing washer, middle sleeve, ball valve and lower sleeve center are run through and are provided with sampler, one end of described sampler is connected with carrying handle, the other end of described sampler extend in the pipeline and is provided with, and the sampler bottom is provided with the sampling diaphragm.
During the utility model work, the bottom of sampler is urged to the bottom of pipeline by carrying handle, after a period of time, sampler is upwards lifted, in this process, owing to have certain pressure in the pipeline, take sewage in the process out of for fear of lifting again, after the sampling diaphragm passes through ball valve, close ball valve, the sampler that will have biological diaphragm is again taken out.Compared with prior art, the beneficial effects of the utility model are that the utility model is simple in structure, and it is convenient, easy to operate to install, and can not influence in the use to produce and safety.The utility model can be used in the sewer line of field in the case study of sewage corrosion and scaling.
More safe and reliable in order further to guarantee operating process, the side of described middle sleeve is equipped with blowdown valve.Lift in the process, close ball valve after, can the air in the middle sleeve be drained by blowdown valve, further guarantee the reliability of operating.
For fear of the corrosion that sampler is received sewage, the bottom of described sampler is connected with the sampling insulation rod, and described sampling diaphragm is arranged on sampling insulation rod bottom.In the sampling process, make the sampling insulation rod be immersed in the sewage.
In order to make the sampling diaphragm pipeline inwall of can fitting, further improve measuring accuracy, described sampling diaphragm is an arc.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 carrying handle, 2 sampler, 3 upper bushes, 4 packing washers, 5 middle sleeves, 6 ball valves, 7 lower sleeves, 8 pipelines, 9 sampling insulation rods, 10 sampling diaphragms, 11 blowdown valves.
Embodiment
A kind of biological membrane sampler that is used for the oilfield sewage pipeline as shown in Figure 1, comprise the upper bush 3 that from top to bottom is coaxially arranged with, middle sleeve 5 and lower sleeve 7, link to each other through packing washer 4 between upper bush 3 and the middle sleeve 5, link to each other through ball valve 6 between middle sleeve 5 and the lower sleeve 7, lower sleeve 7 is installed on the pipeline 8, upper bush 3, packing washer 4, middle sleeve 5, ball valve 6 and lower sleeve 7 centers are run through and are provided with sampler 2, one end of sampler 2 is connected with carrying handle 1, the other end of sampler 2 extend in the pipeline 8 and is provided with, and sampler 2 bottoms are provided with sampling diaphragm 10, the side of middle sleeve 5 is equipped with blowdown valve 11, the bottom of sampler 2 is connected with sampling insulation rod 9, sampling diaphragm 10 is arranged on sampling insulation rod 9 bottoms, and sampling diaphragm 10 is an arc.
In the utility model when work, be urged to the bottom of pipeline 8 with the bottom of sampler 2 by carrying handle 1, makes sampling diaphragm 10 be fitted on pipeline 8 inwalls, after a period of time, sampler 2 is upwards lifted, in this process, owing to have certain pressure in the pipeline 8, take sewage in the process out of for fear of lifting again, after sampling diaphragm 10 passes through ball valve 6, close ball valve 6, open blowdown valve 11 simultaneously, air in the middle sleeve 5 is discharged, and sampler 2 taking-ups that will have the diaphragm 10 of sampling again get final product.
The utility model is not limited to the foregoing description; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
