Abstract
The utility model provides a split corrosion fatigue test environmental box comprising a box body, wherein a through hole for the penetration of a shaft-shaped test sample is formed in the center of the box body; the box body is of a two-petal structure which is symmetrical about an axis, and comprises a left petal box body and a right petal box body; the axially bonded surfaces of the left pedal box body and the right petal box body are fastened and fixed through a convex pin and a groove, and the two end faces of the left pedal box body and the right petal box body are fastened at the neck of the shaft-shaped test sample; a corrosive medium inlet is formed in the upper part of the left petal box body; a corrosive medium outlet is formed in the lower part of the right petal box body; the corrosive medium circulates in the box body through the corrosive medium inlet and the corrosive medium outlet. The split corrosion fatigue test environmental box is small in size and convenient to assemble; the split corrosion fatigue test environmental box is well matched with the test sample, and is well targeted; as the capacity of loading the corrosive medium is small, test expenditure can be saved; the damage of a fatigue testing machine caused by leakage is reduced; besides, the corrosive medium is supplied circularly during testing and the testing accuracy is improved; as the split corrosion fatigue test environmental box moves up and down along with the test sample in the testing process, the damage of a sealing element is reduced and the service life of the sealing element is long; consequently, the leakage probability of the corrosive medium is reduced.
Description
Technical field
The utility model relates to metal material mechanics performance test field, refers to particularly a kind of split-type corrosion fatigue test environmental cabinet.
Background technology
Boats and ships and ocean structure are exposed to seawater, can inevitably be subject to the corrosion of seawater and produce corrosion fatigue.Corrosion fatigue can be accelerated Crack Extension, reduces the fracture toughness of material, reduce critical crack size, makes structural crack initiation life and crack propagation life greatly shorten, and causes boats and ships and ocean structure significantly to reduce serviceable life.For the serviceable life of Estimation of Ship and the reduction of ocean structure intensity time and structural steel, carrying out boats and ships and ocean structure is very requisite with the Corrosion Fatigue Properties research of steel.Carrying out of corrosion fatigue test must possess two conditions, and the one, can carry out the professional fatigue tester of fatigue loading, the 2nd, when guaranteeing torture test, sample is in the environmental cabinet of corrosion simulation environment always.But the etchant solution in environmental cabinet or gas is in case reveal, and will cause the damage that is corroded of expensive fatigue tester vitals.Therefore, corrosion fatigue test has directly affected the carrying out of corrosion fatigue test with the design and use of environmental cabinet.
Tradition corrosion fatigue test environmental cabinet, its size is larger, and maintain static, corrosion fatigue sample and upper lower clamp all are immersed in the corrosion environment case, extend to outside environmental cabinet by the two ends extension rod, again by fatigue tester to the extension rod on-load pressure, this design often needs the corrosive medium amount used larger, cost compare is high.And under long-term fatigue load effect, extension rod and environmental cabinet rub for a long time, have seriously shortened the serviceable life of environmental cabinet O-ring seal, in case sealing goes wrong, a large amount of outflows of the corrosive medium of leakage will cause than macrolesion fatigue tester.Chinese utility model patent CN200620130240.4 " a kind of salt fog corrosion fatigue test unit " discloses a kind of salt fog corrosion fatigue test unit, this device water is as a casing part, can seal salt fog, prevent from revealing, and the corrosion environment case can be with the testing machine back and forth movement, sample fatigue break rear box can separate, and prevents that casing from damaging.But this device only can be used for salt air corrosion, other toxic gas such as H
2S etc., if use this device toxic gas will be in the sample fracture casing enter air after separately, welding; Be not suitable for the corrosion test that adopts liquid corrosive medium yet.There is very large limitation in this device in corrosion fatigue test field use.
Summary of the invention
The purpose of this utility model is exactly to overcome the defective that existing corrosion fatigue test environmental cabinet exists, and provides a kind of gaseous state, liquid corrosive medium of being applicable to, compact size, the split-type corrosion fatigue test environmental cabinet of good seal performance.
for achieving the above object, the split-type corrosion fatigue test environmental cabinet that the utility model is designed, comprise casing, described casing center is provided with the through hole that passes for axle shape sample, its special character is: described casing is two lobe formula structures of axis symmetry, comprise left lobe casing and right lobe casing, be fastened by protruding pin and groove between the axial faying face of described left lobe casing and right lobe casing, the both ends of the surface of described left lobe casing and right lobe casing are fastened on the neck of axle shape sample, described left lobe casing top is provided with the corrosive medium import, described right lobe lower box is provided with the corrosive medium outlet, corrosive medium circulates in casing by corrosive medium import and corrosive medium outlet.
Further, described left lobe casing and right lobe casing are tied up fixing by the rubber ring that is looped around its periphery.Like this, can further strengthen being fixedly connected with of left lobe casing and right lobe casing.
Further, seal by stop-leak compound or sealing gasket between the faying face of described left lobe casing and right lobe casing.Like this, can improve both sealings.
Further, described left lobe casing and right lobe casing are made by the Corrosion Resistant Frp material.Like this, can extend the serviceable life of casing, reduce experimentation cost.
The relatively traditional corrosion fatigue test environmental cabinet of the utility model has the following advantages: 1) compact size, easy to assembly, good with the sample coupling, only sample parallel portion test section is carried out corrosion fatigue, more possesses specific aim, and because carrying corrosive medium capacity is few, can save the test expense on the one hand; On the other hand, in case leak, the fatigue tester degree of damage that relatively traditional corrosion fatigue test environmental cabinet causes is much smaller; 2) the design at the trial corrosive medium adopt the forcing pump circulation to supply with, constantly circulation is supplied with and is guaranteed that concentration of medium can be with not the carrying out and reduce of corrosion process, measuring accuracy is more accurate; 3) the design moves up and down with sample in process of the test, reduces the loss of seal member, and longer service life reduces the corrosive medium Leakage probability.
