Description

Technical Field

[0001] This invention relates to the field of material testing equipment technology, and in particular to a comparative testing device and method for gas sealing materials. Background Technology

[0002] Methane gas extraction is a process closely linked to coal mining, during which methane gas is released. Methane gas is a toxic hydrocarbon gas, similar to natural gas, but in mines, it can pose a serious threat to the health and even lives of workers. Therefore, to ensure safe production and the health of workers, it is essential to extract methane gas from mines to control its levels. Methane gas extraction is not only for safety reasons but also necessary for the development of new energy sources and the implementation of relevant national policies. During the development of new energy sources, methane gas in the mine can have safety impacts on mining operations and may also pollute the environment. Therefore, special attention should be paid to the handling of methane gas during the mining process.

[0003] Properly sealing the extraction boreholes and improving extraction efficiency are urgent problems to be solved in gas extraction, which also facilitates the comprehensive utilization of extracted gas. There are various gas sealing materials available, and selecting the appropriate one is crucial. Therefore, a comparative testing device capable of comparing various parameters such as sealing performance and water resistance is needed.

[0004] Based on this, the present invention aims to propose a comparative detection device and method for gas sealing materials, so as to achieve the effect of simultaneous detection of multiple sealing materials. Summary of the Invention

[0005] To overcome the drawback of the wide variety of existing gas sealing materials, which necessitates comparative experiments for selection, this invention provides a gas sealing material comparative testing device and method for simultaneously testing multiple sealing materials.

[0006] A gas sealing material comparison and testing device includes a base, a central shaft, a sleeve, a placement frame, and a test tube. The central shaft is vertically fixed to the center of the base. The sleeve is slidably connected to the central shaft via a spline. The placement frame is radially connected to the sleeve. The test tube can be fixed in the placement frame by a snap-fit. The device also includes a main bearing slider, a temperature sensor, a pressure tube, and a digital display. The sleeve is provided with a vertical convex key. The main bearing slider is slidably connected to the sleeve via the convex key. The temperature sensor and the pressure tube are spaced apart on the side of the main bearing slider. The pressure tube is equipped with a digital display. The temperature sensor and the pressure tube can be respectively connected to the test tube.

[0007] A further improved solution is that the upper end of the test tube is provided with a threaded opening, and the lower end of the pressure tube is provided with a threaded sleeve that can be rotated to engage with the threaded opening.

[0008] A further improved solution includes a first support rod and a second support rod, which are alternately fixed to the side of the main bearing slider. The temperature sensor is slidably connected inside the first support rod through the slider, and the pressure tube is fixed to the end of the second support rod.

[0009] A further, even better solution is to have radial slits at the bottom of the test tube.

[0010] A further improved solution is to provide a torsion ring at the upper end of the main bearing slider, with anti-slip grooves on the side of the torsion ring.

[0011] A further improved solution includes a return spring and a water storage tank. The return spring is located between the sleeve and the central shaft, and the water storage tank is connected to the base, allowing the test tube to be immersed in the water storage tank.

[0012] A further improved solution includes a locking rod, which is rotatably connected to the lower end of the central shaft. The end of the locking rod is provided with a bent portion, which can limit and fix the lower end of the sleeve by locking.

[0013] A further, even better solution is to connect a torsion spring between the lever and the central shaft.

[0014] Based on the aforementioned gas sealing material comparison and testing device, a testing method for the gas sealing material comparison and testing device is proposed, as follows:

[0015] S1. Place the three types of sealing materials to be tested into three test tubes respectively, and then place the test tubes into the placement rack.

[0016] S2. During material generation, rotate the main bearing slider to adjust the infrared temperature sensor to point at the test tube. The temperature sensor will continuously monitor each sealing material separately to achieve real-time data monitoring and acquisition.

[0017] S3. After the material is formed, rotate the main bearing slider and close the test tube through the threaded sleeve at the lower end of the pressure tube. Then press the main bearing slider to move the sleeve downward and immerse the test tube into the water storage tank.

[0018] S4. Pressurize the test tube through the pressure tube. By direct observation, the sealing effect of the sealing material on the test tube with radial threads can be judged. At the same time, the relevant pressure data is recorded by the digital display. This allows for comparison of various data performances of three different sealing materials during and after molding, thereby judging their actual use effect.

[0019] The present invention has the following advantages: After the sealing material is placed in the test tube, the temperature sensor is connected to the test tube by rotating the main bearing slider. The temperature sensor will monitor the temperature change of the sealing material in real time during the molding process. After the sealing material is molded, the pressure tube is connected to the test tube by the threaded sleeve, and then the test tube is immersed in the water storage tank. This allows the sealing performance of the sealing material in the test tube with radial cracks to be detected. This device can conveniently provide the experimenters with the different experimental data they need. Attached Figure Description

[0035] Example: A comparative testing device for gas sealing materials, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a base 1, a central shaft 2, a sleeve 3, a placement frame 4, and a test tube 5. The central shaft 2 is vertically fixed to the center of the base 1. The sleeve 3 is slidably connected to the central shaft 2 via a spline. The placement frame 4 is radially connected to the sleeve 3. The test tube 5 can be fixed inside the placement frame 4 by snap-fit. A threaded end 501 is provided at the upper end of the test tube 5. A threaded sleeve 10 is rotatably provided at the lower end of the pressure tube 9. The threaded sleeve 10 can mate with the threaded end 501 to improve the airtightness inside the test tube 5. A radial slit 502 is provided at the bottom of the test tube 5. After the material is placed in the test tube 5, the radial slit 502 is used to provide sealing conditions for the sealing material. The sealing quality of the sealing material on the radial slit 502 can be accurately represented in the digital display 11. The device also includes a main bearing slider 6, a temperature sensor 8, a pressure tube 9, and a digital display 11. The sleeve 3 The device is equipped with a vertical convex key 301, through which the main bearing slider 6 is slidably connected to the sleeve 3. A torsion ring 7 is provided at the upper end of the main bearing slider 6, and an anti-slip groove is provided on the side of the torsion ring 7 to facilitate the operation of the main bearing slider 6 by the operator. Temperature probes 8 and pressure tubes 9 are arranged at intervals on the side of the main bearing slider 6. The pressure tubes 9 are equipped with a digital display 11. The temperature probes 8 and pressure tubes 9 can be connected to the test tubes 5 respectively. This device is equipped with three test tubes 5, and the three temperature probes 8 and three pressure tubes 9 are arranged alternately on the side of the main bearing slider 6. Three different sealing material samples are placed in the test tubes 5 for reaction. The main bearing slider 6 is rotated to connect the temperature probes 8 to the test tubes 5. The temperature probes 8 will monitor the temperature of the material in the test tubes 5 in real time. When the pressure tubes 9 are connected to the test tubes 5, the tightness of the test tubes 5 can be detected.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first support rod 601 and a second support rod 602. The first support rod 601 and the second support rod 602 are alternately fixed to the side of the main support slider 6. The temperature sensor 8 is slidably connected to the first support rod 601 through the slider, thereby adjusting the detection angle of the temperature sensor 8 for the needs of comparative experiments. The pressure tube 9 is fixed to the end of the second support rod 602.

[0037] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, it also includes a return spring 12 and a water storage tank 13. The return spring 12 is set between the sleeve 3 and the central shaft 2. The water storage tank 13 is connected to the base 1 by welding. The test tube 5 can be immersed in the water storage tank 13. Sufficient liquid (hereinafter, all liquids refer to water) is added to the water storage tank 13. Then, the sleeve 3 is moved downward by the main bearing slider 6. During this period, the clamping rod 14 can fix the sleeve 3 by clamping. At this time, the test tube 5 will be placed in the liquid. At this time, by pressurizing the test tube 5, there are two effects. First, the sealing degree of the sealing material to the radial crack 502 of the test tube 5 can be detected by direct observation. Second, the liquid enters the test tube 5 through the radial crack 502 and comes into contact with the sealing material. Whether the combination of the sealing material and water affects its sealing performance can be observed.

[0038] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a locking rod 14, which is rotatably connected to the lower end of the central shaft 2. A torsion spring is connected between the locking rod 14 and the central shaft 2. The end of the locking rod 14 is provided with a bent part, which can limit and fix the lower end of the sleeve 3 by locking.

[0039] Based on the aforementioned comparative testing device for gas sealing materials, a testing method for this device is proposed, as follows:

[0040] S1. Place the three types of sealing materials to be tested into three test tubes 5 respectively, and then place the test tubes 5 into the placement rack 4.

[0041] S2. During material generation, rotate the main bearing slider 6 to adjust the infrared temperature sensor 8 to point towards the test tube 5. The temperature sensor 8 will continuously monitor each sealing material separately to achieve real-time monitoring and acquisition of data.

[0042] S3. After the material is formed, rotate the main bearing slider 6 and close the test tube 5 through the threaded sleeve 10 at the lower end of the pressure tube 9. Then press the main bearing slider 6 to make the sleeve 3 move downward, and the test tube 5 will be immersed in the water storage tank 13.

[0043] S4. Pressurize the test tube 5 through the pressure tube 9. By direct observation, the sealing effect of the sealing material on the test tube 5 with radial threads can be judged. At the same time, the relevant pressure data is recorded through the digital display 11. This allows for comparison of various data performances of three different sealing materials during and after molding, thereby judging their actual use effect.
