Abstract
The utility model relates to the field of petrochemical testing in a power system, and particularly relates to a standard gas sampling device which comprises an injector and is characterized in that a fixing ring is arranged in the middle of an injector cylinder, connecting leading rods are respectively arranged on two sides of the fixing ring, a cross beam vertical to the cylinder is arranged at the other ends of the connecting leading rods, a threaded hole is formed in the cross beam, a center line of the threaded hole is coincident with the axial line of the cylinder, an adjusting lead screw is arranged in the threaded hole, a handle is arranged at one end of the adjusting lead screw, a needle handle base matched with a needle handle is arranged at the other end of the adjusting lead screw, two sides of the needle handle base are respectively connected with a sliding rod, the other end of the sliding rod is matched with a sliding groove in each connecting leading rod, metering marking lines are arranged on the connecting leading rods, a pulling rod of the sampling injector is pulled to a set milliliter place during use to ensure that a limit screw is slowly screwed in a thread groove and stops screwing until being in tight contact with the pulling rod. The pulling length of the pulling rod is limited through the limit screw, and thus the function of quantitatively collecting gas is achieved. The standard gas sampling device has the advantages of novel structure, convenience in operation, accuracy in sampling quantization, and the like.
Description
Technical field
The present invention relates to a kind of utensil for oiling test field in electric system, is the calibrating gas sampler that a kind of quantitatively draw standard gas carries out chromatography test specifically.
Background technology
With the component concentration of gas chromatography determination Dissolved Gases in Insulating Oil, be that power supplying and generating enterprises judges whether operating oil-filled power equipment exists the faults such as overheated, electric discharge, ensure the effectively effective means of operation of power grid security.To utilize syringe to get gas from the oil de-getting in the committed step of oil dissolved gas being carried out to gas chromatographic analysis.Because instrument has strict requirement (being generally 0.5mL) to sample introduction tolerance, the general syringe that adopts samples now, because syringe quantitatively judges by staff, often produces air inlet error, causes measurement result deviation.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and quantitatively calibrating gas sampler accurately of a kind of easy to operate, sampling is provided.
The present invention can reach by following measure:
A kind of calibrating gas sampler, comprise syringe, it is characterized in that injector syringe middle part is provided with set collar, the both sides of set collar are respectively equipped with to connect draws bar, the other end that bar is drawn in connection is provided with the crossbeam vertical with syringe, crossbeam is provided with threaded hole, the center line of threaded hole and the dead in line of syringe, in threaded hole, be provided with adjusting screw(rod), adjusting screw(rod) one end is provided with handle, the other end of adjusting screw(rod) is provided with the needle handle seat matching with needle handle, needle handle seat both sides are connected with slide bar respectively, the other end of slide bar is with to be connected the chute drawing on bar in mating connection, draw bar and be provided with metering delineation line.
Syringe needle described in the utility model is provided with lower suction hole, middle suction hole and upper suction hole, lower suction hole is arranged on syringe needle foremost, it exports ovalize, middle suction hole and upper suction hole are separately positioned on the pin wall on syringe needle middle part and syringe needle top, when use, extract the gas of different aspects simultaneously, improve accuracy of detection.
When the utility model uses, sampling injector pull bar is pulled to and sets milliliter place, by slowly DRIVE SCREWS groove of limited screw, until with pull bar close contact after stop, limit pull bar pull-out length by limited screw, reach the effect of quantitative gas, there is the advantages such as novel structure, easy to operate, sampling is quantitatively accurate.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown be a kind of calibrating gas sampler, comprise syringe, the structure of syringe and the interconnected relationship between them are same as the prior art, this does not repeat, of the present utility modelly be characterised in that injector syringe 1 middle part is provided with set collar 2, set collar 2 is generally connected with syringe through retaining thread, the both sides of set collar 2 are respectively equipped with to connect draws bar 3, the other end that bar 3 is drawn in connection is provided with the crossbeam vertical with syringe 4, crossbeam 4 is provided with threaded hole, the dead in line of the center line of threaded hole and syringe 1, in threaded hole, be provided with adjusting screw(rod) 5, adjusting screw(rod) 5 one end are provided with handle 6, the other end of adjusting screw(rod) 5 is provided with the needle handle seat 8 matching with needle handle 7, needle handle seat 8 both sides are connected with slide bar 9 respectively, the other end of slide bar 9 is with to be connected the chute drawing on bar 3 in mating connection, draw bar and be provided with metering delineation line 10, in addition, syringe needle described in the utility model is provided with lower suction hole, middle suction hole and upper suction hole, lower suction hole is arranged on syringe needle foremost, it exports ovalize, middle suction hole and upper suction hole are separately positioned on the pin wall on syringe needle middle part and syringe needle top, when use, extract the gas of different aspects simultaneously, improve accuracy of detection.
When the utility model uses, sampling injector pull bar is pulled to and sets milliliter place, by slowly DRIVE SCREWS groove of limited screw, until with pull bar close contact after stop, limit pull bar pull-out length by limited screw, reach the effect of quantitative gas, there is the advantages such as novel structure, easy to operate, sampling is quantitatively accurate.
