Description
Technical field
The present invention relates to technical field of petroleum extraction, particularly a kind of quantitative sampling valve.
Background technology
Oil is a kind of thickness, dark brown liquid.There is oil storing upper crustal some areas, and principal ingredient is the potpourri of various alkane, naphthenic hydrocarbon, aromatic hydrocarbon.In oil extraction process, early stage needs the oil product carrying out oil well to sample, to obtain the important informations such as the oil offtake of oil well, quality and oil-field development data.The sample cock that current oil field uses mostly is common hand wheel type flashboard valve, the handwheel that common hand wheel type flashboard valve comprises valve body and opens or closes for application valve body, and the valve body of common hand wheel type flashboard valve is arranged on crude oil pipe outside by a short tube.When sampling, rotate handwheel, open hand wheel type flashboard valve, liquid sprays from the outlet of short tube.
Employing aforesaid way has the following disadvantages: 1. hand wheel type flashboard valve is arranged on crude oil pipe outside, the crude oil sample taken out flows out from oil pipe tube wall, when opening described handwheel, the dead oil being attached to viscosity on tube wall larger is taken out of together by by the fluid of oil pipe to Short Tube Orifices, the sample that representative that can not be real will gather, the therefore information brought of the more difficult crude oil measuring oil pipe internal flow exactly usually.2. catch with vessel and chemically examine from the oil of short tube ejection, easily make oil sample be polluted in sampling process, therefore can not ensure the accuracy of oil assay.3. adopt such device can not control when sampling to sample number, oil sample can not be extracted by automatic ration, lack and can not reach experiment aequum, needed again to gather, many then can cause waste.
Summary of the invention
The object of the present invention is to provide one can control sampling amount and prevent the contaminated quantitative sampling valve of oil sample.
For achieving the above object, basic technology scheme of the present invention is to provide quantitative sampling valve, comprises valve body, be provided with gear in valve body, the slide over side walls of valve body is connected with initiatively tooth bar, and initiatively tooth bar is provided with pull bar, the handheld terminal of pull bar is positioned at outside valve body, and initiatively tooth bar is connected with gears meshing; Valve body also slidably connects driven tooth bar on the sidewall relative with active tooth bar, and driven tooth bar is connected with gears meshing; Also be provided with import and outlet in valve body, import is positioned on the movement locus of driven tooth bar, and the lower end of import is provided with limited block, and the movement locus that outlet is positioned at initiatively tooth bar is positioned at the bottom of body wall.
In above-mentioned basic technology scheme, the import of valve body is connected with oil pipeline, and the outlet of valve body is connected with sampling capsule.Pushing drawing rod, initiatively tooth bar can along sidewall slide downward, and the movement locus that outlet is positioned at initiatively tooth bar is positioned at the bottom of valve body wall, and when active tooth bar slides down to bottom, initiatively outlet can be blocked in the back side of tooth bar.Meanwhile, initiatively tooth bar and gears meshing, can rotate by driven gear when initiatively tooth bar moves down, and driven tooth bar also same gears meshing, moving up of driven tooth bar can be driven during pinion rotation, import is positioned on the movement locus of driven tooth bar, after driven tooth bar moves up, import can be opened, and oil sample can flow in valve body, when the oil level in valve body is equal with import, namely reach the quantity of sampling.Pull hand lever again, initiatively tooth bar can along sidewall upward sliding, now outlet can be opened, oil sample just can flow to sampling capsule, meanwhile, initiatively the slip of tooth bar can cause the rotation of gear, and the rotation of gear can drive driven tooth bar slide downward, import can be blocked in the back side of driven tooth bar, prevents the oil in oil pipe from continuing to flow to valve body.The lower end of import is provided with limited block, carries out spacing to driven tooth bar, prevents driven tooth bar from continuing slide downward and import is opened.
The present invention arrange initiatively tooth bar, driven tooth bar respectively with gears meshing, when promote initiatively tooth bar time, close outlet, by the transmission of gear, driven tooth bar is moved up, opens import, put into oil sample inlet valve body, when the oil level in valve body is equal with import, pull initiatively tooth bar, open outlet, release measured oil sample, import can be blocked by driven tooth bar under the transmission of gear simultaneously, thus reaches the object of quantitative sampling.This device can not make oil sample directly be exposed in air, decreases the contaminated possibility of oil sample; Adopt valve body splendid attire oil sample, can measure the amount of sampling, there will not be too much waste, the very few phenomenon needing repeated sampling; The whole result that arranges is simple, easy to operate, very applicable, can use in every field liquid sampling.
Preferred version 1 to the further optimization of basic technology scheme obtains: the junction of the back side of described active tooth bar, the back side of driven tooth bar, pull bar and valve body is equipped with caulking gum, caulking gum can strengthen sealing, prevents from revealing at the junction oil sample of import, outlet and pull bar and valve body.
Preferred version 2 to the further optimization of basic technology scheme obtains: the handheld terminal of described pull bar is provided with draw ring, conveniently promotes pull bar and pulls, and regulates the position of initiatively tooth bar more accurately.
Preferred version 3 to the further optimization of basic technology scheme and preferred version 2 obtains: described pull bar is made up of folding chain, when pulling or promoting initiatively after tooth bar, a part because of pull bar extends to outside valve body, namely the pull bar outside collapsible valve body, be fastened on valve outer wall, to pull bar and active tooth bar fixation, prevented the slip of initiatively tooth bar, keep away manual-free to hold always, reduce labour.
Preferred version 4 to the further optimization of basic technology scheme obtains: the sidewall of described valve body is transparence, the sidewall of valve body is provided with scale mark, transparence can be used for the situation of observing oil sample in valve body, observe scale mark, can the oil sample amount of selecting extraction as required, instead of the oil level in valve body must be made equal with import.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of quantitative sampling valve embodiment of the present invention;
Valve body 1, gear 2, initiatively tooth bar 3, pull bar 4, driven tooth bar 5, import 6, limited block 7, outlet 8.
