For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0032] Figures 1 to 8 illustrate a high-temperature, high-pressure bulging material testing system according to an embodiment of the present invention. This system and method can be used to test a sample 353 under high temperature and high pressure conditions. It may include a pressure control module, a temperature control module, a detection module, an overpressure protection module 340, and a control unit. The pressure control module includes a gas supply unit and a pressure control unit 100. The gas supply unit is connected to the pressure control unit 100 via a gas pipe 200. The detection module includes a frame 300, a loading unit 330, a forward detection unit 320, and a lateral detection unit 310. The loading unit 330 is disposed within the frame 300 and is used to load and clamp the sample 353. The loading unit 330 has a first window 400 and a second window 410. An air inlet 336 is provided. A forward detection unit 320 detects deformation data on the front of the sample 353 through a first window 400, and a lateral detection unit 310 detects deformation data on the side of the sample 353 through a second window 410. The air inlet 336 is connected to the pressure control unit 100 through an air pipe 200 and transmits air pressure to the sample 353. An overpressure protection module 340 is connected to the loading unit 330. The temperature control module includes a temperature sensor and a heating unit. The heating unit is located inside the loading unit 330 to heat the sample 353, and the temperature sensor is located on the side close to the sample 353. The control unit is electrically connected to the air supply unit, the pressure control unit 100, the loading unit 330, the forward detection unit 320, the lateral detection unit 310, the temperature sensor, and the heating unit. The sample 353 is placed inside the loading unit 330. The control unit controls the heating unit to heat the entire loading unit 330. The heat from the loading unit 330 is transferred to the sample 353. After the temperature sensor on one side of the sample 353 detects that the temperature of the sample 353 has reached the specified temperature, it feeds back the data to the control unit. The control unit then controls the heating unit to stop heating. The control unit uses a pneumatic gas supply unit and a pressure control unit 100. High-pressure gas passes through the gas supply unit, the pressure control unit 100, and the loading unit 330 in sequence, supplying pressure to one side of the sample 353 and generating pressure on the sample 353. The forward detection unit 320 detects the deformation data of the front of the sample 353 through the first window 400 and feeds it 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 it back to the control unit. The entire process, except for the placement of the sample 353, is automatically operated by the system. The system has good overall airtightness and heating and heat preservation performance. It can still detect the deformation data of the front and side of the sample 353 normally under high temperature and high pressure conditions. The sample 353 is not affected by external interference.

[0033] In one specific embodiment, the supply pressure of the gas supply unit is determined by actual demand and the sealing performance of the testing equipment.

[0034] In one specific embodiment, the gas supply unit supplies gas at a pressure of 1MPa-30MPa.

[0035] In this embodiment, the gas pressure supplied by the gas supply unit is preferably 10 MPa.

[0036] In one specific embodiment, the heating temperature of the heating unit is determined by the power of its own heating element, the upper limit of the temperature tolerance of the detection equipment itself, and the detection requirements.

[0037] In one specific embodiment, the heating temperature of the heating unit is 20℃-800℃.

[0038] In one specific embodiment, the gas supply unit supplies an inert gas, such as helium, neon, argon, krypton, xenon, or radon. The inert gas prevents gases like oxygen in the air from reacting chemically with the sample 353 at high temperatures, thus avoiding a weakening of the sample 353's physical properties and improving the accuracy of the test.

[0039] In one specific embodiment, the pressure control unit 100 includes a pressure box 110, a pressure control valve 140, a pressure gauge 120, and a pressure control panel 130. The pressure control valve 140 is disposed inside the pressure box 110, and the pressure gauge 120 and the pressure control panel 130 are disposed on the upper part of the pressure box 110. The user can observe the pressure change through the pressure gauge 120 and control the pressure of the output gas through the pressure control panel 130.

[0040] Figures 7 and 8 show that in one embodiment, the loading unit 330 may include a base, a loading member 350, and a movable member 360. The base is mounted on the frame 300, the loading member 350 is mounted inside the base, and the loading member 350 has a mounting groove 351. The movable member 360 is movably mounted in the mounting groove 351, and the sample 353 is placed in the mounting groove 351. The movable member 360 abuts against the sample 353 and fixes the sample 353. By clamping and fixing the sample 353 on both sides by the movable member 360 and the loading member 350, it is possible to prevent the sample 353 from being pushed out of the loading unit 330 due to excessive pressure.

[0041] In one specific embodiment, the movable member 360 and the loading member 350 are connected by threads. The movable member 360 abuts against the sample 353 under the threaded pressure and gradually increases the applied pressure so that the sample 353 can be firmly fixed by the movable member 360 and the loading member 350.

[0042] In one specific embodiment, sealing gaskets 352 are provided on both sides of the sample 353. The sealing gaskets 352 are on both sides of the sample 353 and abut against the loading member 350 and the moving member 360 to play a sealing role. At the same time, they increase the pressure area of ​​the sample 353 to reduce the pressure and reduce the damage to the sample 353.

[0043] Figures 7 and 8 show that in one embodiment, the movable member 360 may include an inner movable groove 361. The movable member 360 has a through hole on the side away from the movable groove 361. The through hole is a first window 400. The movable groove 361 can reduce the area that abuts against the sample 353, and only abut against the edge of the sample 353, thereby increasing the detection area of ​​the forward detection unit 320.

[0044] Figures 7 and 8 show that in one embodiment, the loading unit 330 may include an extension member 370. The extension member 370 has a through portion 371 and a stop portion 372. The diameter of the through portion 371 is smaller than the diameter of the through hole, and the diameter of the stop portion 372 is larger than the diameter of the through hole but smaller than the diameter of the movable groove 361. The stop portion 372 is disposed in the movable groove 361. The through portion 371 passes through the through hole, and the stop portion 372 abuts against the sample 353. The axial displacement of the stop portion 372 is restricted by the movable member 360.

[0045] In one specific embodiment, the stop portion 372 is provided with an elastic element, which is connected to the stop portion 372 and the movable element 360 respectively. The rebound element is in a compressed state, and the outward expansion force of the rebound element causes the extension element 370 to abut against the sample 353.

[0046] Figures 6 and 7 show that in one embodiment, the second window 410 may be disposed on the base, with the second window 410 positioned directly opposite the passage portion 371. The lateral detection unit 310 is a laser detection sensor, which detects the displacement distance of the passage portion 371 through the second window 410, thereby converting it into data on the actual maximum shape change of the sample 353.

[0047] In one specific embodiment, the base includes a body 331, a first connecting part 332, and a second connecting part 333. An air inlet 336 is provided on a plane at one end of the body 331 to allow high-pressure air to enter. The plane at the other end of the body 331 is an opening for placing a loading component 350 and a movable component 360. A transparent partition is also provided at the opening for sealing. The first connecting part 332 extends from the body 331 and has a first channel 334 inside. A second window 410 is provided inside the first channel 334. One end of the first channel 334 opens towards the position of the movable component 360, and the other end faces the lateral detection unit 310. The second connecting part 333 extends from the body 331 and has a second channel 335 inside. 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.

[0048] Figures 7 and 8 show that in one embodiment, the loading component 350 may include an annular groove on its outer surface, and an electromagnetic induction coil as the heating unit. The electromagnetic induction coil is disposed in the annular groove and can directly heat the entire loading component 350, with the heat from the loading component 350 being transferred to the sample 353.

[0049] In one specific embodiment, the heating unit can be in the form of resistance wire heating or the like.

[0050] Figures 4, 5, and 8 show that in one embodiment, the overpressure protection module 340 may include a pressure relief hole 363 on the movable part 360, a pressure relief pipe 341 connected to the base and communicating with the air passage of the loading unit 330, an air outlet branch pipe 343 on the pressure relief pipe 341, a regulating valve 342 on the air outlet branch pipe 343, a pressure relief branch pipe 344 on the pressure relief pipe 341, and a rupture diaphragm 345 sleeved at the outlet of the pressure relief branch pipe 344. When the regulating valve 342 is opened, high-pressure air can enter the body 331. The pressure at which the rupture diaphragm 345 is ruptured by the air pressure is much lower than that of other components. Therefore, when the sample 353 is ruptured, the surge in air pressure first ruptures the rupture diaphragm 345, and then the high-pressure air is discharged from the rupture diaphragm opening, preventing high-pressure air from damaging other components and extending the service life of the equipment.

[0051] In one specific embodiment, the pressure relief hole 363 of the movable part 360 is a number of evenly distributed arc-shaped holes. The arc-shaped holes can increase the pore area, so that when the sample 353 is broken by high-pressure gas, the high-pressure gas cannot be discharged in time, which would damage other parts and improve the service life of the equipment.

[0052] Figures 1 to 3 show that in one embodiment, the pressure control module may include several pressure control units 100, which are respectively connected to several loading units 330, forward detection units 320, and lateral detection units 310. This forms multiple channels for detection, allowing for the simultaneous testing of several samples 353, greatly improving equipment efficiency.

[0053] Figure 1 shows that in one embodiment, the forward detection unit 320 may include a support frame and a three-dimensional vision recognition system. The support frame is disposed on one side of the frame 300, and the three-dimensional vision recognition system is disposed on the support frame. The three-dimensional vision recognition system detects the shape and size of the sample 353 through a first window 400.

[0054] In this invention, Figures 1-8 illustrate the workflow of some embodiments. Sealing gaskets 352 are clamped around both sides of the sample 353. Then, the sample 353 is placed in the loading member 350. The movable member 360 is screwed into the loading member 350 and presses the sample 353 firmly. The heating unit heats the loading member 350, thereby heating the sample 353 to a specified temperature. High-pressure gas is supplied through the gas supply unit, and the pressure control unit 100 controls the output of gas at a specified pressure to the air inlet 336. The high-pressure gas enters the loading member 350 and reaches one side of the sample 353, exerting pressure on the sample 353 and causing it to deform. At this point, if the forward detection unit 320 performs detection... Without the extension member 370, 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 lateral detection unit 310 is to be used, the extension member 370 needs to be installed in the moving part 360. The lateral detection unit 310 can detect the distance of the extension member 370 moving back and forth through the second window 410, thereby converting it into data on the actual maximum shape change of the sample 353 and feeding the data back to the control unit. If the sample 353 is ruptured by high-pressure gas, the high-pressure gas will flow from the second channel 335 to the explosion-proof membrane 345. The explosion-proof membrane 345 will rupture due to the pressure of the high-pressure gas, and the high-pressure gas will be discharged from the pressure relief branch pipe 344 without damaging other parts of the system.

[0055] Figure 9 illustrates a high-temperature, high-pressure bulging material testing method according to one embodiment of the present invention, including the following steps:

[0056] Step S1: Place the sample 353 into the loading unit 330;

[0057] Step S2: The control unit controls the heating unit to heat the sample 353 to the specified temperature;

[0058] 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.

[0059] In 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 it back to the control unit, and the lateral detection unit 310 detects the deformation data of the side of the sample 353 through the second window 410 and feeds it back to the control unit, thus completing the detection.

[0060] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention.
