Abstract
A container for material and oil compatibility tests comprises a main body, a front close cover, a rear close cover and three or four guide bars each possessing screw threads at two ends; the main body consists of a bellows, and a front flange disc and a rear flange cover respectively welded at the front end and the rear end of the bellows; the front close cover covers a front flange and is connected with the front flange disc via bolts; the rear close cover covers a rear flange; each guide bar penetrates the front close cover, the front flange disc, the rear flange disc and the rear close cover; the positions of each guide bar, which are at the front side of the front close cover and at the rear side of the front flange disc, are respectively provided with a front spacing nut and a rear spacing nut, and the distance between the front spacing nut and the rear spacing nut is larger than the thickness of the front close cover and the front flange disc; the positions of each guide bar, which are at the front side of the rear flange disc and the rear side of the rear close cover, are respectively provided with a front locking nut and a rear locking nut, and the front locking nut and the rear locking nut fixes the corresponding guide bar, the rear flange disc and the rear close cover together; and the rear close cover is provided with two through holes respectively for oiling and vacuum pumping, and the through holes are connected with gate valves. The container for the material and oil compatibility tests is capable of effectively isolating air and compensating the volume needed by oil thermal expansion.
Description
Technical field
The present invention relates to material and oil compatibility test container.
Background technology
Transformer all needs to carry out compatibility test with transformer oil to the various materials that use in fuel tank in manufacturing.What at present compatibility test container used adopted is wide-necked bottle, fills with transformer oil in wide-necked bottle, and material is placed in wide-necked bottle, and it is in the drying box of 140 ° that wide-necked bottle is placed on temperature, carries out the mensuration of relevant parameters for up to three months.In process of the test, transformer oil can not have any contact with ambient atmosphere, once contact cannot correctly judge whether test findings meets the requirements, so in whole process of the test, must completely cut off air, but wide-necked bottle cannot seal, can not seal, because transformer oil has the problem of individual thermal expansion.Drying box cannot completely cut off air completely, although at present adopt drying box vacuumized, but unavoidably in the process of heating, transformer oil can and oxygen, water vapor etc. can react, cause the mensuration of parameter to be forbidden, affect the reliability of test findings.
Summary of the invention
The object of the invention is to propose a kind of material and oil compatibility test container, this container can effectively completely cut off air, compensates the needed volume of oily thermal expansion.
For achieving the above object, the present invention takes following technical scheme: this material and oil compatibility test have main body with container, front capping, rear seal-cover and the many threaded guide poles of two ends tool, main body is by corrugated tube and being welded on before corrugated tube, before rear end, rear stub forms, described front capping covers on forward flange and by bolt and is connected with forward flange dish, described rear seal-cover covers on rear flange, guide pole is through front capping, forward flange dish, rear stub and rear seal-cover, before the rear side of the front side in front capping on guide pole and forward flange dish is respectively equipped with, rear stop nut, before, the distance of rear stop nut is greater than the thickness of front capping and forward flange dish, front side in rear stub on guide pole and the rear side of rear seal-cover are respectively equipped with front set nut and rear set nut, before, rear set nut is guide pole, rear stub and rear seal-cover are fixed together, on rear seal-cover, be provided with two through holes that are respectively used to oiling and vacuumize, on aperture, be connected with gate valve.
Front shrouding is provided with watch window, and high temperature resistant organic glass transparent panel is installed on window position
The present invention has following good effect: 1, main body of the present invention adopts corrugated tube, the length of corrugated tube is scalable, the variable volume of container namely, when heating, oil in container can be because being heated volumetric expansion, this container can launch along with oily volumetric expansion, compensates the needed volume of oily thermal expansion, prevents the potential safety hazard that pressure raises and brings to container.2, the present invention adopts shrouding sealing, on front shrouding, is provided with gate valve, by gate valve, carries out vacuum oil, can effectively completely cut off air, guarantees in whole process of the test, and oil with atmosphere, any contact does not occur.3, front shrouding of the present invention is provided with view window, the variation of observable internal tank.4, of the present invention have a guide pole, prevents in heating process the irregular deformation of container.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is main body schematic diagram of the present invention.
Embodiment
See Fig. 1, this material and oil compatibility test container, have main body 1, front capping 2, rear seal-cover 3 and the many threaded guide poles 6 of two ends tool, take 3 to 4 as good, and the present embodiment adopts 4 guide poles 6.Main body 1 is comprised of with the forward and backward ring flange 1-2, the 1-3 that are welded on corrugated tube 1-1 front and back ends corrugated tube 1.It is upper that described front capping 2 covers forward flange 1-2, and front capping 2 is some to be connected with forward flange dish 1-2 by bolt 10.Described rear seal-cover 3 covers on rear flange 1-3.For guaranteeing that container has good sealing, simultaneously in order to guarantee in long term heat ageing test, rubber seal is aging, and that between front capping 2 and forward flange 1-2, adopt is red copper O-ring seal 7-1, also adopts red copper O-ring seal 7-2 between rear seal-cover 3 and rear flange 1-3.
Described guide pole 6 is through the pilot hole on front capping 2, forward flange dish 1-2, rear stub 1-3 and rear seal-cover 3, the rear side of front side in front capping 2 on guide pole 3 and forward flange dish 1-2 is respectively equipped with forward and backward stop nut 4-1,4-2, distance h between forward and backward stop nut 4-1,4-2 is greater than the thickness d of front capping 2 and forward flange dish 1-2, give the leeway of a stretching, extension of corrugated tube 1-1, h value can be according to oily swell increment free adjustment simultaneously.The rear side of the front side in rear stub 1-3 on guide pole 6 and rear seal-cover 3 is respectively equipped with front set nut 5-1 and rear set nut 5-2, and forward and backward set nut 5-1,5-2 are fixed together guide pole 6, rear stub 1-3 and rear seal-cover 3.Owing to having guide pole, the stretching, extension of corrugated tube 1-1 can only be carried out along guide pole, prevents the irregular deformation of container.Extending range is placed restrictions between front limit nut 4-1 and rear stop nut 4-2.
