Technical field
Aid when the present invention relates to the test of nuclear fuel and material out-pile corrosive nature, the specifically special-purpose sample hanger of a kind of nuclear fuel and material out-pile corrosion test.
Background technology
For guaranteeing the safe operation of nuclear reaction power reactor, New-type fuel and material must carry out the corrosion test of operating mode in the long-term simulation heap to detect its corrosion resistance at out-pile first before entering heap.Wherein, the corrosive nature test must be carried out in the customization high temperature and high pressure kettle of nuclear equipment special use.Because of kind, the specification of fuel and material different, divide excellent type, ball-type and template etc. such as fuel, material has again tubulose, tabular and bar-shaped etc., so it is loaded down with trivial details to carry out put procedure for difform sample when now nuclear fuel and material being carried out corrosion test, wastes time and energy.
Summary of the invention
The object of the invention is to solve now the problem that process when placing for difform nuclear fuel and material sample is loaded down with trivial details, waste time and energy, the special-purpose sample hanger of a kind of nuclear fuel and material out-pile corrosion test is provided, it is convenient to difform sample is placed by cylinder, and then it is convenient, time saving and energy saving to place sample manipulation when making nuclear fuel and material out-pile corrosion test.
Purpose of the present invention is achieved through the following technical solutions: the special-purpose sample hanger of a kind of nuclear fuel and material out-pile corrosion test, the cylinder that comprises hook, disk and a plurality of lower end closures, described hook connecting is connected to the central part of disk upper surface, the sidewall upper of a plurality of cylinders all is connected in the lower surface of disk, described disk be provided with cylinder quantity quite and run through the sample through hole of disk upper and lower end face, a plurality of sample through holes are corresponding one by one with the openend position of a plurality of cylinders.The present invention uses front need and at the kettle cover of high-temperature high-pressure reaction kettle hanging point is set in advance, and sample is placed in the cylinder by the sample through hole, by hook the present invention is hung on the hanging point of kettle cover again.
Affect cylinder to the depositing of sample for fear of the sample through hole, as preferably, described sample through hole is the manhole of aperture and barrel bore size coupling.
Described disk consists of a plurality of first medium openings that run through the disk upper and lower end face; Described cylinder side wall and bottom are provided with the second medium opening in a plurality of connection cylinder interior and the external world.The first medium opening was used for promoting the heat interchange of disk upper and lower and the exchange of corrosive medium to flow when the present invention used, the second medium opening flows for the exchange of the heat interchange inside and outside the promotion cylinder and corrosive medium, so, can guarantee to deposit in a plurality of cylinders the corrosion environment that has homogeneous behind the sample around the sample.
The central part of described disk lower surface is connected with O type ring.Can carry out a plurality of tandems when the present invention uses from top to bottom hangs, wherein, topmost the hook of hanger hangs over the hanging point of kettle cover lower end, and from top to bottom the hook of second hanger is hooked on the O type ring of the top hanger, articulate successively, thereby reach the sample quantities of the single test that is multiplied.
Because austenitic stainless steel corrosion resistance and good and cost are relatively cheap, as preferably, the material of described hook, cylinder, disk and O type ring is austenitic stainless steel.So, the present invention is applicable to the operating mode of nuclear fuel and material out-pile long-term corrosion performance test, and can be repeatedly used, for longer abrasion cycle, and such as 30-40 days, and relatively harsher etching condition, such as OH
-The alkaline water corrosive medium that concentration is higher or the higher experimental enviroment of temperature, each parts can not rupture because of corrosion yet among the present invention, and then can not cause dropping and assembling of sample.
Compared with prior art, the present invention has following beneficial effect: (1) the present invention includes the disk of hook, cylinder and coupling hook and cylinder, when using, the present invention can articulate by hook, and carry out corrosion test after by cylinder the sample of sheet, pipe, rod, ball, line, the various shapes such as thread being placed, when using, the present invention is applicable to difform sample, simple operation when placing sample, time saving and energy saving.
(2) the present invention can be in the kettle that utilizes high temperature and high pressure kettle of larger limit under the standard code space, each sample all independently is placed in the cylinder, it is convenient to put/take a sample, guarantee the complete contact corrosion medium of each sample, can avoid the contact between the sample to disturb, and then can avoid causing corrosion data deviation to occur because of contact interference between the sample.
(3) the present invention is provided with hook and O type ring, can carry out a plurality of serial connection hooks when the present invention uses, so can increase single test enter the still sample size, take full advantage of the interior space of kettle of high temperature and high pressure kettle.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after Fig. 1 topples over.
The corresponding name of Reference numeral is called in the accompanying drawing: 1, hook, 2, cylinder, 3, disk, 4, O type ring.
Embodiment
The present invention is described in further detail below in conjunction with embodiment and accompanying drawing, but embodiments of the present invention are not limited to this.
As shown in Figure 1, the special-purpose sample hanger of a kind of nuclear fuel and material out-pile corrosion test comprises hook 1, cylinder 2 and disk 3, and wherein, hook 1, cylinder 2 and disk 3 all adopt the resistant material manufacturing.Hook 1 is connected in the central part of disk 2 upper surfaces, cylinder 2 upper end open and lower end closure, and the quantity of cylinder 2 is a plurality of, and the sidewall upper of a plurality of cylinders 2 all is connected in the lower surface of disk 3, and a plurality of cylinders 2 are evenly distributed below disk 3.Disk 3 is provided with the sample through hole that runs through disk 3 upper and lower end faces, and wherein, the sample through hole is identical with the quantity of cylinder 2, and a plurality of sample through hole is corresponding one by one with the openend position of a plurality of cylinders 2.
