The sample 353 is not disturbed by the outside.

[0034] In a specific embodiment, the pressure supplied by the gas supply unit is determined by actual demand and sealing performance of the detection equipment.

[0035] In a specific embodiment, the gas pressure supplied by the gas supply unit is 1 MPa-30 MPa.

[0036] In the embodiment, the gas supplied by the gas supply unit has a pressure of 10 MPa.

[0037] In a specific embodiment, the heating temperature of the heating unit is determined by the power of the heating element itself, the upper limit of the temperature that the detection device itself can withstand, and the detection requirements.

[0038] In a specific embodiment, the heating temperature of the heating unit is 20-800°C.

[0039] In a specific embodiment, the gas supplied by the gas supply unit is an inert gas, such as helium, neon, argon, krypton, xenon, radon, etc. The inert gas can avoid chemical reactions between oxygen and the sample 353 due to high temperature, which can weaken the physical properties of the sample 353 and improve the accuracy of the test.

[0040] In a specific embodiment, the pressure control unit 100 includes a gas tank 110, a gas pressure control valve 140, a pressure gauge 120, and a gas pressure control panel 130.

The sample 353 is placed in the mounting groove 351, and the movable piece 360 abuts against the sample 353 and fixes the sample 353. The sample 353 is clamped and fixed by the movable piece 360 and the loading piece 350, which can avoid the sample 353 from being pushed out of the loading unit 330 due to excessive pressure.

[0042] In a specific embodiment, the movable piece 360 and the loading piece 350 are connected by threads. The movable piece 360 abuts against the sample 353 and gradually increases the applied pressure under the thread rotation, so that the sample 353 can be fixed firmly by the movable piece 360 and the loading piece 350.

[0043] In a specific embodiment, the sample 353 is provided with sealing gaskets 352 on both sides. The sealing gaskets 352 are arranged on both sides of the sample 353 and abut against the loading piece 350 and the movable piece 360, which can play a sealing role and increase the pressure receiving area of the sample 353 to reduce the pressure and damage to the sample 353.

[0044] Figure 7 AndFigure 8 The active element 360 can include an inner active groove 361 in an embodiment. The active element 360 is provided with a through hole on the side away from the active groove 361, and the through hole is the first window 400.

[0045] Figure 7 And Figure 8 The loading unit 330 can include an extension element 370 in an embodiment. The extension element 370 is provided with a passing part 371 and a cutoff part 372. The diameter of the passing part 371 is smaller than that of the through hole, and the diameter of the cutoff part 372 is larger than that of the through hole but smaller than that of the active groove 361. The cutoff part 372 is arranged in the active groove 361, the passing part 371 is arranged in the through hole, the cutoff part 372 abuts to the sample 353, and the cutoff part 372 is limited in axial displacement by the active element 360.

[0046] In a specific embodiment, the cutoff part 372 is provided with a resilient element, and the resilient element is connected to the cutoff part 372 and the active element 360, respectively. The resilient element is in a compressed state, and the elastic force of the resilient element expanding outward makes the extension element 370 abut to the sample 353.

[0047] Figure 6 And Figure 7 The second window 410 can be arranged on the base in an embodiment. The second window 410 is arranged opposite to the passing part 371. The lateral detection unit 310 is a laser displacement detection sensor, which detects the displacement distance of the passing part 371 through the second window 410, thereby converting the data of the actual maximum shape change of the sample 353.

[0048] In a specific embodiment, the base includes a body 331, a first connecting part 332, and a second connecting part 333. The air inlet 336 is arranged on the plane of one end of the body 331, and high-pressure air enters through the air inlet 336. The plane of the other end of the body 331 is an opening, which is used to place the loading element 350 and the active element 360.

One end of the second channel 335 is connected to the body 331, and the other end of the second channel 335 is connected to the overpressure protection module 340.

[0049] Figure 7 And Figure 8It is shown that the loading member 350 can include an annular groove on the outer surface of the loading member 350 in an embodiment, and the heating unit is an electromagnetic induction coil, which is arranged in the annular groove. The electromagnetic induction coil can directly heat the entire loading member 350, and the heat of the loading member 350 is transferred to the sample 353.

[0050] In a specific embodiment, the heating unit can be in the form of a resistance wire.

[0051] Figure 4 、 Figure 5 and Figure 8 It is shown that the overpressure protection module 340 can include a pressure relief hole 363 arranged on the movable member 360, a pressure relief pipeline 341 connected to the base and in gas communication with the loading unit 330, a gas outlet branch pipe 343 arranged on the pressure relief pipeline 341, a regulating valve 342 arranged on the gas outlet branch pipe 343, a pressure relief branch pipe 344 arranged on the pressure relief pipeline 341, and an anti-burst film 345 sleeved on the outlet of the pressure relief branch pipe 344. The regulating valve 342 can open the high-pressure air in the body 331. The pressure at which the anti-burst film 345 is burst by the air pressure is much smaller than that of other components. When the sample 353 is burst, the air pressure is first burst through the anti-burst film 345, and then the high-pressure air is discharged from the anti-burst film opening. This avoids damage to other components by high-pressure air and improves the service life of the equipment.

[0052] In a specific embodiment, the pressure relief hole 363 of the movable member 360 is a plurality of uniformly distributed arc-shaped holes. The arc-shaped holes can increase the area of the air hole, avoid the high-pressure gas from being unable to be timely discharged when the sample 353 is burst by the high-pressure gas, and damage other components, thereby improving the service life of the equipment.

[0053] Figures 1 to 3 It is shown that the pressure control module can include a plurality of pressure control units 100 in an embodiment, and the plurality of pressure control units 100 are respectively connected to the plurality of loading units 330, the forward detection unit 320, and the lateral detection unit 310. A plurality of channels are formed for detection, and a plurality of samples 353 can be tested at a time, thereby greatly improving the use efficiency of the equipment.

[0054] Figure 1 It is shown that the forward detection unit 320 can include a support frame and a three-dimensional visual identification system in an embodiment. The support frame is arranged on one side of the rack 300, and the three-dimensional visual identification system is arranged on the support frame. The three-dimensional visual identification system detects the shape and size of the sample 353 through the first window 400.

[0055] In the present application, Figures 1-8The working process of the present application in some embodiments is shown. The gasket 352 is clamped on both sides of the sample 353, and then the sample 353 is placed into the loading element 350. The movable element 360 is screwed into the loading element 350 and presses the sample 353. The heating unit heats the loading element 350 to heat the sample 353 to a specified temperature. The gas supply unit supplies high-pressure gas, and the pressure control unit 100 controls the output of the gas with a specified pressure to the gas inlet 336. The high-pressure gas enters the loading element 350 and reaches one side of the sample 353. The high-pressure gas generates pressure on the sample 353 and deforms the sample 353. At this time, if the detection of the forward detection unit 320 is performed, the extension element 370 is not added. The deformation data of the front of the sample 353 is detected through the first window 400 and fed back to the control unit. If the detection of the lateral detection unit 310 is performed, the extension element 370 needs to be added to the movable element 360. The lateral detection unit 310 can detect the distance change of the extension element 370 before and after through the second window 410, so as to convert the actual maximum shape change data of the sample 353 and feed back the data to the control unit. If the sample 353 is broken by the high-pressure gas, the high-pressure gas will flow from the second channel 335 to the anti-burst film 345. The anti-burst film 345 is broken due to the pressure of the high-pressure gas, and the high-pressure gas is discharged from the pressure relief branch 344, without damaging other parts of the system.

[0056] Figure 9 A high-temperature and high-pressure material expansion test method in an embodiment of the present application is shown, which includes the following steps:

[0057] Step S1, the sample 353 is placed into the loading unit 330;

[0058] Step S2, the control unit controls the heating unit to heat the sample 353 to a specified temperature;

[0059] Step S3, the control unit controls the pressure control unit 100 to supply high-pressure air into the loading unit 330 and pressurize the sample 353;

[0060] Step S4, the forward detection unit 320 detects the deformation data of the front of the sample 353 through the first window 400 and feeds back to the control unit. The lateral detection unit 310 detects the deformation data of the side of the sample 353 through the second window 410 and feeds back to the control unit. The detection is completed.
