Abstract
The utility model relates to an oil guide device of a non-standard oil drain valve of an oil filling equipment, which is used for guiding an oil sample into a sampling bottle or an injector when the non-standard oil drain valve of the oil filling equipment in a power system extracts the oil sample. The structure of the oil guide device is that a fixed part connected with an oil drain valve hole is arranged above an oil guide box; an oil discharging hole is formed in the oil guide box; the lower part of the oil guide box is connected with an oil nozzle. According to the oil guide device, the original sampling valve structure of oil abandoning equipment is not changed, the escape of water and gas which are dissolved in oil of the oil sample are alleviated when a non-standard sampling valve of the oil filling equipment samples the oil, so that the site sampling of the oil filling equipment closely meets the GB7597 requirement, and the test precision is improved; the oil guide device can slow down the flowing speed of oil flow through the oil guide box, so that frequent exchange between the oil sample and air is avoided; the oil guide device is conveniently connected with a sampling three-way device recommended in the GB7597 requirement, and therefore full-sealing sampling is realized.
Description
Technical field
The utility model relates to a kind of auxiliary device drawn oil sample, relate in particular in a kind of electric system when the non-standard fuel outlet valve of oil-filled equipment draws oil sample, oil sample is imported to the non-standard fuel outlet valve oil-guide device of oil-filled equipment in sampling bottle or syringe, can be widely used in the oil-filled equipment sampling works such as electric power system power plant, transformer station.
Background technology
In electric system, the oil-filled equipment sample valve is unified standard not, and the sample valve that each manufacturer adopts is multifarious, brings certain difficulty to the work of operational outfit periodic sampling; GB7597 oil for electric power sampling method requires should be at hermetically sealed and free of contamination situation down-sampling, the oil sample connected mode is reliable, prevent that dissolved water in fuel from dividing and gas is overflowed, avoid air to sneak into and produce a large amount of bubbles in oil while sampling, to guarantee the representativeness of institute's oil recovery sample.
Although the new oil-filled equipment fuel outlet valve of installing is without unified standard in electric system, but each manufacturer also follows the GB7597 requirement gradually, requirement to greatest extent is near the mark, to spot sampling, work brings certain facility, but still have the non-standard sample valve of large number quipments installation or the equipment on-line operation of nonstandardized technique construction and installation in system, these equipment bring inconvenience to later stage sampling work, at first these old equipment fuel outlet valve shapes differ, general oil outlet is thicker, aperture is at 1-2 centimetre, under the oil pressure effect, during sampling, oil sample is spurting, on-the-spot generally the need with the sampling of wide-mouth sampling jar, pour into again in narrow-mouthed bottle or syringe, can't meet sampling requirement, secondly the equipment that the part nonstandardized technique is installed is because of design or defective mounting, make fuel outlet valve and plant bottom case close together, can't be directly with sampling bottle or syringe sampling, thereby make recover the oil and polluted or under-represented, way commonly used is to make oil sample be spurting to spray in the wide-mouth sampling jar, pour into again in narrow-mouthed bottle or syringe, affect the accurate judgement of test figure.
The utility model content
The utility model is for above-mentioned problems of the prior art, a kind of portability is provided and can be applied to the non-standard fuel outlet valve oil-guide device of oil-filled equipment of distinct device, solved in the prior art fuel outlet valve inconvenient problem that draws oil sample.
The technical solution of the utility model is as follows:
Oil-guide device, the top of oil guiding box is provided with the fixed part that connects the valve opening of draining the oil, and oil guiding box is provided with oil outlet, and the bottom of oil guiding box is connected with oil nozzle.
Described fixed part is comprised of screw and mother Luo.
Described screw is provided with anti-slip cap.
Be provided with anti-oil spurts film in described oil guiding box, the injection film of draining the oil is lining in outside the valve opening of draining the oil.
Described anti-oil spurts film is the oil resistant rubber goods.
The endpiece outer wall of described oil nozzle is provided with external thread.
Described oil nozzle is provided with adjusting screw(rod).
The utility model has the advantages of as follows:
1, do not change and abandon the former sample valve structure of oily equipment, reduce the impact of non-standard sample valve on oil sample, reduce that the oil sample dissolved water in fuel divides and the gas loss, reduce test error, improve the accurate judgement to equipment latency fault.
2, make the oil-filled equipment on-site sampling more approach the GB7597 requirement, reduce the accuracy because of fuel outlet valve sample that cause influence recovers the oil, improve test accuracy; By oil guiding box, the equipment oil stream flow velocity of releiving, avoid oil sample and air frequent exchange, and the oil nozzle outer wall is provided with external thread, and the convenient sampling " three-way device " of recommending with GB7597 is connected, thereby realizes hermetically sealed sampling.
3, realize hermetically sealed sampling, avoid in sampling process the pollution of oil sample, prevent that dissolved water in fuel from dividing and gas is overflowed, avoid air to sneak into and produce a large amount of bubbles in oil while sampling, improve the equipment failure judgment accuracy.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
In figure, 1, screw, 2, mother Luo, 3, anti-oil spurts film, 4, oil guiding box, 5, oil nozzle, 6, the valve opening of draining the oil, 7, the oil guiding box oil outlet, 8, regulate the Luo bar.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
In Fig. 1-2, the top of oil guiding box is provided with screw 1 and mother Luo 2 who connects the valve opening of draining the oil, and screw 1 and Luo female 2 forms the fixed part of oil-guide device, screw 1 is provided with anti-slip cap, be convenient to manually screw, reconcile screw, realize that oil-guide device is connected with the tight of equipment sample valve; Anti-oil spurts film 3 adopts the oil resistant soft rubber to manufacture capsule, is lining in drain the oil valve opening 6 and oil guiding box 4 oil sample ejection while preventing from sampling; Oil guiding box is provided with oil outlet 7, and the bottom of oil guiding box is connected with oil nozzle, and oil nozzle is provided with adjusting screw(rod) 8, and oil nozzle 5 endpiece outer walls are provided with external thread, and the internal thread of external thread and three-way device or conduit is complementary, the convenient connection.
