Description
Technical field
The invention belongs to insulating medium technical field of analytical instruments, especially one is exclusively used in transformer insulation oil on-site sampling device.
Background technology
At present, the general glass syringe adopting all size of transformer insulation oil chromatography test sampling, and at the scene in sampling process, glass syringe sealing sampling process is comparatively complicated.After using Rubber end sealing after sampling, due to glue head quality problems or ageing of rubber, may cause coming off or syringe poorly sealed.In oscillation extraction process, glass syringe may come off from draw-in groove and damaged, causes sample preparation failure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one to be exclusively used in transformer insulation oil on-site sampling device.
The present invention solves its technical matters and takes following technical scheme to realize:
One is exclusively used in transformer insulation oil on-site sampling device, comprise core stick harness, the circular cylinder body that center pit is sleeved on the circular lid on core stick harness and is equipped with circular lid, at described core stick harness left end spinning cylindric core stick harness handle, core stick harness right-hand member is fixedly mounted with the core stick harness head mated with circular cylinder body internal diameter, core stick harness middle part surface is fixedly mounted with many equally spaced containing mark rings, described circular lid end face is shaped with the air-vent running through circular lid, groove shirt rim to the right, direction is shaped with at circular lid periphery, the pipeline be communicated with circular cylinder body inside is shaped with at the upper side wall right-hand member of described circular cylinder body, pipeline is installed exhaust oil extraction valve, the pipeline be communicated with circular cylinder body inside is shaped with at circular cylinder body right side bottom surface, pipeline is installed oil pumping valve.
And described core stick harness head outside surface is fixedly mounted with Cu jacket layer, and the external diameter of Cu jacket layer is identical with circular cylinder body internal diameter, Cu jacket layer in circular cylinder body for closely cooperating.
And described containing mark ring stops to 100ml from right to left by 20ml, and spacing 10ml equidistant arrangement, the sign volume of described containing mark ring is identical with the circular cylinder body inner volume be separated out between core stick harness head.
And the described inner barrel space of pipeline location corresponding to bottom circular cylinder body of installing exhaust oil extraction valve is 10ml.
And, all equipped sealing cap of described gas oil extraction valve and oil pumping valved tube road junction place.
And the recess width that described circular lid periphery is shaped with groove shirt rim is identical with the sidewall thickness of circular cylinder body, and sidewall and groove are plug-in wringing fit.
And described sampler all adopts stainless steel to make except copper sheathcoat.
Advantage of the present invention and good effect are:
1, apparatus of the present invention avoid oil to contact with air, reduce the error that sampling process produces.
2, apparatus of the present invention core plug push rod is marked with containing mark, can realize sampling and quantitatively once complete, the air contact avoiding laboratory second metering to produce and quantitative error.
3, apparatus of the present invention sample with traditional approach compared with simple and easy to do, avoid using multiple assembly (threeway, conduit, syringe etc.) joint connection in site to complete sampling.
4, apparatus of the present invention are stainless steel, overcome the shortcoming that traditional glass syringe rapid wear is frangible, avoid the windfall loss of sample in transport, sample making course.
