Description

Technical Field

[0001] The present invention relates to the technical field of electrode boiler seal detection, and specifically relates to a testing device for electrode boiler seals. Background Art

[0002] An electrode boiler is a device that converts electrical energy into heat energy through electrodes to heat water; its working principle is based on the ionic conductivity characteristics of water; in an electrode boiler, the electrodes are directly inserted into the water. When the electrodes are connected to the power supply, the current passes through the water, and the water acts as a resistor. Due to the thermal effect of the current, the water is heated, and then hot water or steam is generated.

[0003] Electrode boilers are mostly used in urban central heating systems. Electrode boilers can be used as heat source devices to provide heating for buildings in the area; especially in areas with rich power resources and high environmental protection requirements, electrode boilers are applied due to their clean and efficient characteristics.

[0004] During the use of an electrode boiler, the seals in the electrode boiler are crucial parts; the electrode boiler seals are components used to prevent the leakage of media such as water and steam inside the electrode boiler and to prevent external air from entering; when the electrode boiler is operating, the inside is in a high-temperature and high-pressure state. If the sealing is not good, it will not only cause heat energy loss and affect the thermal efficiency of the boiler, but may also lead to safety accidents; for example, steam leakage may scald operators, and water leakage may cause problems such as electrical short circuits.

[0005] Therefore, during the production of the seals for electrode boilers, the compression and rebound characteristics of the seals are important factors affecting their sealing performance. If the compression and rebound characteristics of the seals are poor, when the electrode boiler starts and stops frequently or the working conditions change, the seals will undergo multiple compression and rebound cycles, which will cause the rebound effect of the seals to decline, resulting in problems such as a decrease in the sealing effect of the seals.

[0006] Based on the above problems, when producing seals, it is necessary to test the compression and rebound characteristics of the seals; when testing the compression and rebound of seals in existing factories, the method is mostly dedicated to a special machine, that is, a testing device can only test one size of seal at a time and cannot test multiple different sizes of seals simultaneously; this will lead to a low testing efficiency.

[0042] First sliding grooves 135 are respectively formed on the lower inner walls of the installation disk 13, the first ring 131 and the second ring 132; first sliding blocks 136 are respectively arranged on the lower outer sides of the first ring 131, the second ring 132 and the installation column 133; the first sliding block 136 on the outer wall of the first ring 131 is slidably connected in the first sliding groove 135 on the inner wall of the installation disk 13; the first sliding block 136 on the outer wall of the second ring 132 is slidably connected in the first sliding groove 135 on the inner wall of the first ring 131; the first sliding block 136 on the outer wall of the installation column 133 is slidably connected in the first sliding groove 135 on the inner wall of the second ring 132;

[0043] A telescopic device 14 is arranged below the testing machine table 1, and the telescopic end of the telescopic device 14 is connected to the lower end of the installation column 133;

[0044] A hydraulic cylinder 15 is arranged at the upper end of the installation plate 12, and an extrusion disk 16 is arranged below the installation plate 12, and the upper end of the extrusion disk 16 is connected to the output end of the hydraulic cylinder 15; a third ring 161, a fourth ring 162 and a fifth ring 163 are arranged at the lower end of the extrusion disk 16; when the extrusion disk 16 moves downward, the third ring 161, the fourth ring 162 and the fifth ring 163 respectively enter the placement grooves 134 formed on the installation disk 13, the first ring 131 and the second ring 132;

[0045] The specific working process is as follows;

[0046] When testing the seal, first, the staff controls the telescopic device 14 under the testing machine table 1 to work. The telescopic device 14 is an electric telescopic rod, and the electric telescopic rod moves upward. The electric telescopic rod pushes the mounting column 133 upward. And in the initial state, the upper end faces of the mounting column 133, the first ring 131, the second ring 132, and the mounting plate 13 are on the same horizontal plane. When the mounting column 133 moves upward, the first slider 136 on the outside of the mounting column 133 slides upward inside the first chute 135 on the inside of the second ring 132. Until the first slider 136 on the outside of the mounting column 133 moves to the top of the first chute 135 on the inside of the second ring 132, at this time, the telescopic device 14 continues to extend and retract upward, and the mounting column 133 continues to move upward. At this time, the first slider 136 on the outside of the mounting column 133 pushes the first chute 135 on the inside of the second ring 132, so that the mounting column 133 pushes the second ring 132 through the first slider 136 on its outside, making the second ring 132 move upward with the mounting column 133. During the upward movement of the second ring 132, the first slider 136 on the outside of the second ring 132 slides upward inside the first chute 135 on the inside of the first ring 131 until the first slider 136 on the outside of the second ring 132 moves to the top of the first chute 135 on the inside of the first ring 131. The mounting column 133 drives the first ring 131 to continue to move upward. During this process, the second ring 132 pushes the first ring 131 upward through the first slider 136 provided on its outside. During the upward movement of the first ring 131, the first slider 136 on the outside of the first ring 131 moves upward inside the first chute 135 on the inside of the mounting plate 13 until the first slider 136 on the outside of the first ring 131 moves to the top of the first chute 135 on the inside of the mounting plate 13, and then the telescopic device 14 stops moving. So that the mounting column 133, the second ring 132, the first ring 131, and the mounting plate 13 present a stepped structure.

[0047] After the mounting column 133, the second ring 132, the first ring 131, and the mounting plate 13 form a stepped structure, the staff sleeved the seals of corresponding sizes on the outer walls of the corresponding mounting column 133, the first ring 131, and the second ring 132. That is, the smallest-sized seal is sleeved on the outer wall of the mounting column 133, the largest seal is sleeved on the outer wall of the first ring 131, and the medium-sized one is sleeved on the outer wall of the second ring 132. After the sleeving is completed, the telescopic device 14 contracts. It should be especially noted that before sleeving the seal, the thickness and height dimensions of the seal are measured and recorded.

[0048] When the telescopic device 14 contracts, first, the mounting column 133 drives the mounting column 133 to move downward. The first slider 136 outside the mounting column 133 supports the first chute 135 inside the second ring 132. Therefore, when the mounting column 133 moves downward, the second ring 132 moves downward at the same time. Similarly, the first slider 136 outside the second ring 132 supports the first chute 135 outside the first ring 131, and the first ring 131 moves downward synchronously. During this process, the seal sleeved outside the mounting column 133 gradually moves into the placement groove 134 opened inside the upper end of the second ring 132. The seal sleeved outside the second ring 132 moves into the placement groove 134 opened inside the upper end of the first ring 131. The seal sleeved outside the first ring 131 moves into the placement groove 134 opened inside the upper end of the mounting plate 13. Until all the seals enter the corresponding placement grooves 134, at this time, the upper end faces of the mounting column 133, the second ring 132, the first ring 131, and the mounting plate 13 are on the same horizontal plane.

[0049] After the seal enters the placement groove 134, the hydraulic cylinder 15 on the upper end of the mounting plate 12 expands and contracts. When the hydraulic cylinder 15 expands and contracts, it pushes the extrusion disc 16 downward. During the process of the extrusion disc 16 moving downward, the third ring 161, the fourth ring 162, and the fifth ring 163 on the extrusion disc 16 all move downward. Until the third ring 161 enters the placement groove 134 opened inside the upper end of the mounting plate 13. The fourth ring 162 enters the placement groove 134 opened inside the upper end of the first ring 131, and the fifth ring 163 enters the placement groove 134 opened inside the upper end of the second ring 132. After the third ring 161, the fourth ring 162, and the fifth ring 163 all enter the corresponding placement grooves 134, the hydraulic cylinder 15 continuously extrudes the extrusion disc 16. The extrusion disc 16 extrudes the seals inside the corresponding placement grooves 134 through the third ring 161, the fourth ring 162, and the fifth ring 163. The extrusion duration is two hours. Thus, one-side extrusion testing of seals with different sizes is realized. Compared with using different types of testing mechanisms for seals with different sizes, the detection efficiency is improved.

[0050] After reaching the extrusion duration, the telescopic device 14 extends upward, driving the mounting column 133 upward. During this process, the mounting column 133, the second ring 132, and the first ring 131 all move upward until the seals sleeved on the outer sides of the mounting column 133, the second ring 132, and the first ring 131 move out of the corresponding placement grooves 134. At the same time, the mounting column 133, the second ring 132, the first ring 131, and the mounting plate 13 form a stepped structure. At this time, the staff only needs to remove the seals from the mounting column 133, the second ring 132, and the first ring 131. After removal, measure and record the thickness and height of the seals, and compare the measured data with the data before extrusion to obtain the compression and rebound characteristics of the seals. And during this process, a stepped structure is formed by the mounting column 133, the second ring 132, the first ring 131, and the mounting plate 13, making it convenient to install and remove mounting parts of different sizes, and further improving the detection efficiency of the seals.

[0051] Embodiment 2:

[0052] As Figures 2 to 5 shown; second sliding grooves 164 are formed in the inner walls of the third ring 161, the fourth ring 162, and the fifth ring 163, and second sliding blocks 165 are arranged on the outer walls of the fourth ring 162 and the fifth ring 163. The second sliding block 165 on the outer side of the fourth ring 162 is slidably connected inside the second sliding groove 164 on the inner wall of the third ring 161. The second sliding block 165 on the outer side of the fifth ring 163 is slidably connected inside the second sliding groove 164 on the inner wall of the fourth ring 162.

[0053] The third ring 161, the fourth ring 162, and the fifth ring 163 have the same thickness, and the placement grooves 134 formed at the upper ends of the mounting plate 13, the first ring 131, and the second ring 132 have the same thickness. The thickness of the third ring 161 is the same as the thickness of the placement groove 134 on the mounting plate 13.

[0054] The specific working process is as follows;

[0055] On the basis of the above embodiment, second sliding grooves 164 are formed in the inner walls of the third ring 161, the fourth ring 162, and the fifth ring 163, and second sliding blocks 165 are arranged on the outer walls of the fourth ring 162 and the fifth ring 163, so that the second sliding block 165 on the outer side of the fourth ring 162 is slidably connected inside the second sliding groove 164 on the inner wall of the third ring 161, and the second sliding block 165 arranged on the outer wall of the fifth ring 163 is slidably connected inside the second sliding groove 164 formed on the inner side of the fourth ring 162. In the initial state, the third ring 161, the fourth ring 162, and the fifth ring 163 form a stepped shape, and the horizontal height of the lower end of the fifth ring 163 is the lowest, the horizontal height of the lower end of the fourth ring 162 is the second, and the horizontal height of the lower end of the third ring 161 is the highest.

[0056] At this time, the staff respectively sleeved seals of different sizes on the outer sides of the third ring 161, the fourth ring 162 and the fifth ring 163; then the output end of the hydraulic cylinder 15 extended downward to push the extrusion disc 16, so that the third ring 161, the fourth ring 162 and the fifth ring 163 moved downward synchronously. During the process, the fifth ring 163 first extruded the seal in the placing groove 134 on the outer side of the second ring 132. Then the extrusion disc 16 continued to move downward, and the second slider 165 on the outer side of the fifth ring 163 slid upward in the second chute 164 opened on the inner wall of the fourth ring 162; at this time, the fourth ring 162 slid downward on the surface of the fifth ring 163. During this process, the seal on the outer side of the fifth ring 163 gradually entered the gap between the fourth ring 162 and the fifth ring 163; until the fourth ring 162 contacted the seal in the placing groove 134 on the outer side of the first ring 131; at this time, the fourth ring 162 could not continue to move downward, so that the hydraulic cylinder 15 continued to extend downward, and the third ring 161 slid downward on the outer wall of the fourth ring 162. The seal sleeved on the outer wall of the fourth ring 162 gradually entered the gap between the third ring 161 and the fourth ring 162 until the lower end of the third ring 161 contacted the seal in the placing groove 134 on the mounting disc 13; then the hydraulic cylinder 15 continued to extend downward, so that the extrusion disc 16 pushed the third ring 161, the fourth ring 162 and the fifth ring 163 to move downward. During the process, the lower ends of the third ring 161, the fourth ring 162 and the fifth ring 163 respectively extruded the seals in the placing grooves 134 on the mounting disc 13, the seals in the placing grooves 134 on the first ring 131 and the seals in the placing grooves 134 on the second ring 132, so as to conduct extrusion tests on the seals in the inner placing grooves 134 of the mounting disc 13, the first ring 131 and the second ring 132; so as to detect the resilience characteristics of seals of multiple different sizes at one time; and while the third ring 161, the fourth ring 162 and the fifth ring 163 extruded the seals in multiple placing grooves 134, the part of the first ring 131 without the placing groove 134 would be embedded in the gap between the third ring 161 and the fourth ring 162, and the part of the second ring 132 without the placing groove 134 would be embedded in the gap between the fourth ring 162 and the fifth ring 163, so that the part of the first ring 131 without the placing groove 134 extruded the seal between the third ring 161 and the fourth ring 162; the part of the second ring 132 without the placing groove 134 extruded the seal between the fourth groove and the fifth groove, thereby increasing the number of seals to be detected and increasing the detection of the diversity of seal sizes, improving the detection effect.

[0057] Embodiment 3:

[0058] As Figures 2 to 5 shown; a driving motor 151 is arranged at the output end of the hydraulic cylinder 15, and the output shaft of the driving motor 151 is fixedly connected to the inner wall of the upper part of the extrusion disc 16;

[0059] The mounting disk 13 is slidably connected to the upper end of the testing machine table 1, and the extrusion disk 16 is slidably connected to the output end of the hydraulic cylinder 15; two support rods 17 are evenly arranged at the upper end of the testing machine table 1, and the support rods 17 are symmetrically distributed outside the mounting disk 13. Rotating gear disks 171 are rotatably connected to the opposite surfaces of the two support rods 17; the upper end of the mounting disk 13 has an annular rack structure; the lower outer side of the extrusion disk 16 has an annular rack structure. In the initial state, the gear disk 171 meshes with the annular rack structure at the upper end of the mounting disk 13; when the extrusion disk 16 moves downward, the annular rack on the outer side of the extrusion disk 16 meshes with the upper side of the gear disk 171;

[0060] The specific working process is as follows;

[0061] A driving motor 151 is arranged at the output end of the hydraulic cylinder 15, and the output shaft of the driving motor 151 is fixedly connected to the upper inner wall of the extrusion disk 16, so that when the output end of the hydraulic cylinder 15 pushes the extrusion disk 16 downward, the driving motor 151 is pushed downward synchronously, and at the same time the driving motor 151 rotates, and the driving motor 151 drives the extrusion disk 16 to rotate; on the basis of the above-mentioned Embodiment 2, when the third ring 161, the fourth ring 162 and the fifth ring 163 at the lower end of the extrusion disk 16 extrude the seal in the placing groove 134, the staff can control the driving motor 151 to rotate, and the driving motor 151 drives the extrusion disk 16 to rotate, so that when the seals in the mounting disk 13, the first ring 131 and the placing groove 134 inside the third ring 161 are extruded, the seals can be subjected to torsion from the extrusion disk 16. After the extrusion test of the seals, anti-torque detection can be carried out, thereby improving the detection effect and efficiency;

[0062] And when the extrusion disk 16 moves downward, the lower outer side of the extrusion disk 16 will contact the gear disk 171, and the annular rack on the lower outer side of the extrusion disk 16 meshes with the gear disk 171. When the extrusion disk 16 rotates, the gear disk 171 will be meshed and rubbed by the extrusion disk 16, so that the gear disk 171 rotates on the support rod 17. During the rotation of the gear disk 171, it meshes with the annular rack structure at the upper end of the mounting disk 13, so that the gear disk 171 drives the mounting disk 13 to rotate on the testing machine table 1, and the rotation direction of the mounting disk 13 is opposite to the rotation direction of the extrusion disk 16, so that when the extrusion disk 16 rotates, the mounting disk 13 rotates synchronously, increasing the anti-torque test effect of the two on the seal.

[0069] And at the same time, the elastic member 166 connected to the outer side of the fourth ring 162, the connection part is located at the lower end of the outer side of the fourth ring 162; the elastic member 166 connected to the outer side of the fifth ring 163, the connection part is located at the lower end of the outer side of the fifth ring 163; so that when installing the elastic member 166 on the outer side of the fourth ring 162, the seal is located below the elastic member 166; when installing the elastic member 166 on the outer side of the fifth ring 163, the seal is located below the fifth ring 163;

[0070] On the basis of the above-mentioned second embodiment, when the fourth ring 162 slides downward on the outer side of the fifth ring 163, the seal on the outer side of the fifth ring 163 is squeezed by the end of the first ring 131 where no placement groove 134 is provided on the outer side, and the seal on the outer side of the fifth ring 163 enters the gap between the fourth ring 162 and the fifth ring 163. During the process, the seal on the outer side of the fifth ring 163 squeezes the elastic member 166 between the fifth ring 163 and the fourth ring 162; at the same time, the seal on the outer side of the fourth ring 162 squeezes the elastic member 166 between the fourth ring 162 and the fifth ring 163;

[0071] After the extrusion test of the seal is completed, the hydraulic cylinder 15 retracts upward, the extrusion disc 16 moves upward, and the third ring 161 moves upward synchronously. During this process, the fourth ring 162 is affected by its own gravity and the elastic reset of the elastic member 166 between the third ring 161 and the fourth ring 162, and the fourth ring 162 and the fifth ring 163 remain stationary; until the second slider 165 on the outer side of the fourth ring 162 slides to the bottom of the second chute 164 on the inner side of the third ring 161, the third ring 161 drives the fourth ring 162 to move upward. During this process, the fifth ring 163 remains different. Until the second slider 165 on the outer side of the fifth ring 163 moves to the lower end of the second chute 164 on the inner side of the fourth ring 162, the third ring 161 drives the fifth ring 163 to move upward through the fourth ring 162; until the third ring 161, the fourth ring 162, and the fifth ring 163 form a stepped shape; and then through the elastic reset of the elastic member 166, the elastic member 166 between the third ring 161 and the fourth ring 162 is ejected, and the elastic member 166 between the fourth ring 162 and the fifth ring 163 is ejected; thereby improving the convenience of removing the seal.
