Description
Technical field
This utility model relates to the technical field of oil resistant test device, particularly a kind of new type rubber oil resistant test device.
Background technology
Rubber and goods thereof are modern industry and the modern national defense indispensable accessory of industry, and wherein many accessories often exist
Use in the case of contacting with fluid, such as high-pressure hose, cotton thread pipe, fuel tank, oil tank etc..Due to the development of science and technology, special
The development not being modern national defense science and technology is more and more higher to the requirement of rubber accessory, not only high temperature resistant, low temperature, and needs
The etch etc. of anti-various fluid.In order to characterize rubber and goods thereof the quality of oil resistance under the conditions of a certain, conventional
Method be to be made into sample to carry out oil resistant test, this test is that rubbery sample is put into a hermetically sealed can filling fluid
In, to take out after soaking a period of time under the test temperature of regulation, the performance change before and after then soaking it is measured, bag
Firmness change, Strength Changes etc. before and after including mass change, change in volume and soaking, so that it is determined that this rubber and goods oil resistant thereof
Performance is the most qualified.Owing to the fluid in hermetically sealed can is affected by the high temperature generation expanded and be in fluidized state, if hermetically sealed can
Sealing property is bad, easily causes the fluid in hermetically sealed can and overflows and cause rubbery sample test data fluctuations, and overflow
Fluid the most easily causes potential safety hazards such as catching fire.
The material that prior art seals for hermetically sealed can is mainly the macromolecule material such as rubber seal, oil resistant rubber asbestos sheet
Material, uses rubber or asbestos board sealing ring to seal between oil resistant hermetically sealed can and sealing lid, and by screw pre-pressing structure by close
Capping and sealed shell of tank are locked.And these rubber seal, oil resistant rubber asbestos sheet are at high temperature with at the long-term corrosion of fluid
Under be easily deformed until loss of seal performance, to easily cause locking by artificial locking tight for screw nut simultaneously, thus causes
Test failure.Without separately device in the most existing test tank, sample is easily overlapping and causes test data deviation.Patent
ZL201210489779.9 " a kind of oil resistant hermetically sealed can device for rubber experiment and preparation method thereof " propose a kind of resistance to
Oil seal tank, its structure is the tank mouth end face making one circle placement o-ring groove at hermetically sealed can, simultaneously at oil resistant hermetically sealed can
Making serrated end face groove on tank mouth end face between cavity volume and o-ring groove, the sealing at oil resistant hermetically sealed can covers making one
Individual annular boss, enables this annular boss to stick in the cavity volume of oil resistant hermetically sealed can, makes a circle at sealed tank cap simultaneously and seals
Circle pressure ring, makes sawtooth annular groove on the end face of this sealing ring pressure ring and forms.Sealing ring is pressed in cavity volume by this patent, passes through ring
Shape boss and the isolation of serrated end face groove and buffering, though rubber seal and test(ing) liquid in oil resistant hermetically sealed can cavity can be prevented
Contact, it is to avoid situation that it is at high temperature destroyed occurs, but rubber seal is at high temperature easily deformed, resistance to oil seal
The boss of tank and zigzag structure are very easy to destroy sealing ring, often carry out the oil resistant that an oil resistant test is required to more renew
Sealing ring.Its zigzag structure impact simultaneously, oil resistant hermetically sealed can must coordinate according to certain orientation with sealing lid, Cai Nengshang
Lower sawtooth is fully mated, and its assembling bad also affects sealing effectiveness.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of simple in construction, easy to use, sealing
The new type rubber oil resistant test device effective, test data accuracy is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of new type rubber oil resistant test device, including
Sealing lid, marmem preload ring, metal frame, apertured partition and sealed shell of tank, described sealed shell of tank is at tank mouth
Being provided with tank shoulder, being positioned at the sealed shell of tank position above tank shoulder is tank neck, and the downside sealing lid is provided with cylindrical boss, outside tank neck
Footpath is identical with the cylindrical boss diameter sealing lid, and the outer sheath of tank neck has marmem preload ring, shape memory
Adding up to the height height higher than tank neck of preload ring, the cylindrical boss sealing lid buckles in marmem preload ring, position
Sealing lid lower end in sealed shell of tank is provided with metal frame, is provided with apertured partition in metal frame.
The internal diameter of described marmem preload ring is identical with the external diameter size of tank neck, and marmem pretension
It is matched in clearance between ring and tank neck, between marmem preload ring and cylindrical boss, is similarly matched in clearance.
The height of described tank neck and the summation of cylindrical boss height are higher than the height of marmem preload ring.
The described outer surface of tank neck and the outer surface of cylindrical boss are shiny surface.
Described metal frame is welded on the lower end sealing lid.
Described metal frame is provided with equally distributed aperture.
During test, it is only necessary to sample and fluid are loaded in sealed shell of tank, shape note on the outer sheath of sealed shell of tank tank neck
Recall alloy preload ring, seal and be i.e. placed in after the cylindrical boss covered buckles in marmem preload ring testing heat riser
In test.Along with the rising of test temperature, marmem preload ring internal diameter constantly reduces, fit sealing tank body and close
The projection section of capping, namely reached sealing effectiveness.After off-test, whole device is taken out and is under room temperature, with
The reduction of temperature, marmem preload ring internal diameter increases, and can be easily removed sealing lid, complete oil resistant test.With
Time, rubbery sample is separated by the apertured partition in metal frame, it is to avoid rubbery sample contacts with each other and all contacts fluid with each, gold
Lid is fixing to be connected with sealing to belong to frame, facilitates the feature taken of sample.
This utility model has the advantages that compared to prior art
(1) simple in construction, oil resistant hermetically sealed can tank mouth end face and sealing lid end face are a planar structure, can directly dock
On, marmem preload ring is enclosed within sealed shell of tank and sealing covers, easy for installation and need not specialty installation tool, simultaneously
Easy to process；
(2) sealing effectiveness and good pressure-resistant performance, this utility model uses present situation memorial alloy preload ring to be tightly connected, is
Using the connection of metal and metal, its bonding strength significantly larger than uses the macromolecular materials such as nonmetal rubber seal to play sealing
Effect sealing device, and the fluid in oil resistant hermetically sealed can due to affected by the high temperature and produce part vaporization, its hermetically sealed can
In air pressure will raise, certainly will overflow from the weakest environment of whole device, rubber or oil resistant rubber asbestos sheet are nonmetal
Material, its voltage endurance capability is far below metal, and oil vapour certainly will overflow from these nonmetallic materials, and metal can undertake higher
Pressure, the safety of its oil resistant hermetically sealed can improves；
(3) test data accuracy is high, and this utility model arranges the metal frame of band dividing plate to be separated rubbery sample, it is to avoid
Rubbery sample contacts with each other and each of sample all touches fluid, and metal frame is connected with sealing lid, facilitates putting of sample
The feature taken.
