Material extending performance test is at present mainly at atmosphere at room temperature environment or tests in hot environment, stretch under the multiple concrete environment for use method of testing of performance change behavior of lack of materials, cause material therefor in use to exist certain potential safety hazard, for the variation behavior of test material tensile property in concrete applied environment, the utility model provides under the multiple corrosive medium atmosphere such as gas, liquid, solid, the environmental chamber of test material tensile property, solves the existing weak point of prior art.
Utility model content
The purpose of this utility model, is exactly for the existing deficiency of prior art, and social demand widely, provides a kind of for under the corrosive medium such as gas, liquid atmosphere, the technical scheme of test material tensile property.As long as this environmental chamber is arranged in Material Testing Machine when test, need to set up different environmental baselines according to test, just can solve the test problem of material extending performance index under varying environment atmosphere.
The technical solution adopted in the utility model: a kind of material extending performance test environmental chamber, comprise upper container and lower container, described upper container and lower container connect as one by flange seal; On the side of described lower container, be provided with air intake opening, in lower container, be provided with bare terminal end, described bare terminal end one end is exposed outside lower container through the bottom of lower container, and the other end of bare terminal end is arranged in lower container, and is provided with sample chuck in the end of bare terminal end; On the side of described upper container, be provided with gas outlet, the top of upper container is provided with sensor, is provided with through hole with the upper container tip position that on lower container, sample chuck is corresponding.
In technique scheme, the through hole of described upper container is provided with V-arrangement pressure ring and O circle.
In technique scheme, in the sample chuck of described bare terminal end, be provided with internal thread.
In technique scheme, between the inside surface of the connecting hole of described flange, be provided with seal groove.
In the utility model, upper and lower container, by being connected to the container that is integrally formed a sealing, can store various test mediums in airtight container, can put into silica gel as needs obtain dry atmosphere, upper and lower container is connected by sending out orchid, and obtain required environment after gland nut sealing; Or obtain different humidity atmosphere after adding different saturated salt solution sealings; Or obtain water logging environment after upper and lower container topped up with water sealing; Or obtain special corrosive environment after adding different etchant solution sealings; Or after sealing, pass into liquid nitrogen by supercharge pump and obtain different low temperature environments, or between the inlet, outlet of environmental chamber connecting small-sized mechanical pump and the container of certain specific gas is housed, after sealing, obtain at specific gas circulation environment, carry out material extending performance test; Also can connect gas tank at the air intake opening of environmental chamber, after sealing, obtain the Special Corrosion gaseous environment that has certain pressure.
When test, by one end of tensile sample, screw in sample chuck by sample end thread, upper container is inserted in sample one end, smooth seal district.Need to set up different environmental baselines according to test, compress V-arrangement pressure ring and O circle by gland nut, make O circle be adjacent to the dynamic seal (packing) effect that sample is realized.Temperature, humidity, pressure transducer need to be installed and with sealings such as gland nuts according to test.To in gland nut on environmental chamber, stretch out the threaded portion of sample, screw in and be arranged on the screw thread chuck in fixture on testing machine, can carry out tension test.
The beneficial effects of the utility model are that the environmental laboratory of this programme can simulate different test environments, fixture has novel structure, is easy to processing, tests reliable, convenient and practical feature, can meet the performance test under multiple environment by side material, avoid the data unicity of testing under existing means of testing.
Brief description of the drawings
