Abstract
The utility model discloses a kind of rubber o-ring corrosion testers, belong to industrial materials and examines detection technique field, the device can simulate military service situation of the rubber o-ring in corrosive environment, rubber o-ring after providing corrosion provides reliable material in the degree of injury of corrosive environment for evaluation rubber o-ring；It can also can examine whether rubber o-ring after corrosion fails, device assembling is simple, has wider practicability by the pressure of the annular space corrosion front and back between the comparison body of rod and shell.
Description
Technical field
The utility model belongs to industrial materials and examines detection technique field more particularly to a kind of rubber o-ring corrosion test
Device.
Background technique
Rubber is widely used in the fields such as petroleum, aviation and military project as common sealed material is done.And rubber o-ring
It is again in these areas common finished product sealing element, evaluates corrosion resistance of the rubber o-ring in corrosive environment, is rubber
Whether safety military service provides foundation to O-ring during service.
Therefore it provides one kind, in corrosive environment, the device of simulation rubber o-ring military service operating condition becomes more important.It is public at present
The device that rubber o-ring is tested in corrosive environment of cloth is also less, " rubber seal performance and corrosivity under a kind of artesian condition
The energy method of inspection and device " provides a kind of experimental provision of rubber o-ring.But there are still following limitations for the device:
(1) it when installing rubber o-ring additional is applied arbitrarily by sealing cover into the groove on sealing cover, is mainly reflected in and installs O-ring and examination additional
It is inconvenient to take out after the completion of testing, and easy damaged O-ring when installation and taking-up；(2) the sealing mechanism of the device is by screwing
Sealing cover makes the O-ring being stuck in sealing cover groove contact compression with seal body, and during screwing, O-ring can be followed
Sealing cover rotates together, at this point, O-ring by with seal body friction and will will receive it is lateral tear, which easily leads to O
Type circle is impaired, does further mechanical test to be subsequent and provides inaccurate O-ring sample；(3) device lacks corrosion front and back pressure
Power compares part, can intuitively identify whether O-ring fails in corrosive environment by the pressure change of corrosion front and back.
Therefore, more really to provide a kind of O-ring detection device, and overcome the shortcomings of existing O-ring detection device,
The utility model proposes a kind of rubber o-ring corrosion testers.
Utility model content
The utility model proposes rubber o-ring corrosion tester, assembling is simple, overcomes the shortcomings of existing apparatus, energy
More really reflect test effect.
The utility model is realized in this way: a kind of rubber o-ring corrosion tester, it is characterised in that: the device by
Clamping cap, ring compression block, shell, the body of rod, fluid channel, valve, pressure gauge and pipeline are constituted；
There is the internal screw thread matched with body of rod external screw thread in the clamping cap, formed in clamping cap with body of rod external screw thread
Overdose space；The ring compression number of blocks is 2, and one end that ring compression block is contacted with rubber o-ring is provided with circular arc ditch
Slot A；The shoulder that the enclosure interior is contacted with rubber o-ring is provided with arc groove B, is provided with fluid channel on shell；It is described
The body of rod be equipped with body of rod external screw thread, arc transition section and 4 arc groove C, the body of rod and shell form annular space.
Clamping cap, ring compression block, shell, the body of rod, valve and the pipeline is made of Hastelloy C alloys -276.
The beneficial effects of the utility model are: (1) assembling process will not cause mechanical damage to rubber o-ring, the device
Military service situation of the energy real simulation rubber o-ring in corrosive environment is damage of the subsequent evaluation rubber o-ring in corrosive environment
Degree provides O-ring after reliable corrosion；(2) pressure of the annular space corrosion front and back between the comparison body of rod and shell can be passed through
Power, whether rubber o-ring fails after capable of intuitively reflecting corrosion.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is structural schematic diagram when the utility model is tested.
In figure: the overdose space formed in 1- clamping cap with body of rod external screw thread, 2- ring compression block, 3- rubber o-ring, 4-
The annular space that container, 5- shell, the 6- body of rod and shell are formed, 7- arc transition section, 8- clamping cap, 9- valve, 10- fluid
Channel, the 11- body of rod, 12- arc groove C, 13- arc groove A, 14- body of rod external screw thread, 15- pipeline, 16- internal screw thread, 17- circle
Arc groove B, 18- pressure gauge.
Specific embodiment
2 pairs of the embodiments of the present invention are further described with reference to the accompanying drawing:
1. rubber o-ring is assembled in the arc groove C of the body of rod by the body of rod by arc transition band, by what is assembled
The body of rod is put into shell, by two ring compressions it is packaged enter shell among, two clamping caps are tightened on the external screw thread with the body of rod,
So that rubber o-ring stress seals；
2. opening valve, the H that is passed through 2MPa is formed in annular space by pipeline to the body of rod and shell2S gas, and record
Temperature in environment at this time closes valve, removes the pressure gauge on pipeline；
3. the device assembled is put into high temperature and high pressure containers, sealing container, 150 DEG C of vessel temp are heated to, and protect
Hold temperature-resistant, the air intake valve for opening container is passed through the H of 10MPa into container2S gas, and close air intake valve；
4. keeping temperature and pressure constant, container withdrawing device is opened after 7 days, the temperature recorded before device is cooled to
When, the pressure in the annular space of the body of rod and shell is measured, and compare in 2MPa before；
It is further stretched test 5. the rubber o-ring on device is removed, record tensile strength and breaks elongation
Rate, and compared with the tensile strength of uncorroded rubber o-ring and elongation rate of tensile failure, corrosive medium is analyzed to RUBBER O type
The degree of injury of circle.
The above does not impose any limitation on the present invention, although the utility model passed through it is above-mentioned
Embodiment discloses, however is not intended to limit the utility model, any person skilled in the art, practical not departing from
In new technique aspects, is made when the technology contents using the disclosure above and change or be modified to a bit the equivalent of equivalent variations
Embodiment, but all contents without departing from technical solutions of the utility model, according to the technical essence of the utility model to the above reality
Any simple modification, equivalent change and modification made by example are applied, are still within the scope of the technical solutions of the present invention.
