Description

Technical Field

[0001] This invention relates to the technical field of valve testing, specifically to a comprehensive testing device for vacuum valve life testing and sealing performance and temperature resistance. Background Technology

[0002] Vacuum valve testing is a core guarantee for the safe operation of vacuum systems. However, existing testing devices for vacuum valves still have some problems. Vacuum valves are used in the bellows welding process. During welding, high-temperature metal vapor is generated between the welding torch and the bellows. After cooling, the high-temperature metal vapor forms welding slag, which can come into contact with or even collide with the vacuum valve, causing damage. Existing testing devices do not have similar testing capabilities and cannot accurately reflect the actual working conditions of existing vacuum valves, leading to inaccurate test results.

[0003] Therefore, how to test the impact of welding slag on the lifespan of vacuum valves during the welding process is a problem that needs to be solved. Summary of the Invention

To complete the testing of vacuum valves, the device includes a third regulating section, a steam transmission section, and a discharge section. When simulating the environment of the vacuum valve, the steam transmission section activates, enabling high-temperature metal vapor to move along the third channel and be discharged from the discharge section. This allows the vapor to be positioned within the test tube, increasing the temperature and concentration of the high-temperature metal vapor. When welding slag testing is required, the third regulating section activates, activating the exhaust section. The exhaust gas lowers the temperature of the high-temperature metal vapor, causing it to form welding slag that moves with the gas. This slag impacts the vacuum valve, simulating the actual welding process. The sealing detection device on the test bench then performs the test, thus completing the lifespan testing of the vacuum valve. Attached Figure Description

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0047] This invention discloses a comprehensive testing device for the life test, sealing performance, and temperature resistance of vacuum valves, with reference to... Figures 1-10 ,include:

[0048] The test bench 1 includes a slag recovery assembly 4 and a test assembly 2 respectively mounted on the test bench 1, a test piece 5 located between the slag recovery assembly 4 and the test assembly 2, a lifting assembly 3 fixedly mounted on the test bench 1, a rotary motor 24 connected to the output end of the lifting assembly 3, and a transmitting assembly 6 mounted on the test assembly 2; as well as multiple sensors mounted on the test bench 1, with each type of sensor having multiple units; the transmitting assembly 6 includes a mounting chamber 61, a third adjustment section 62 and a discharge section 63 mounted on the mounting chamber 61, and a steam transmission section 64 and an exhaust section 65 mounted in the mounting chamber 61; the third adjustment section 62 is connected to the steam transmission section 64, and through the operation of the third adjustment section 62, metal vapor can be transported from the steam transmission section 64 to the discharge section 63 for discharge, or the movement of the steam transmission section 64 can cause the exhaust section 65 to move, thereby allowing gas to mix with metal vapor and be discharged from the mounting chamber 61. By using different types of sensors, data on temperature, pressure, flow rate, image, and vacuum level are collected during the test process. When it is necessary to simulate the environment of the vacuum valve, the steam transmission unit 64 starts working, enabling high-temperature metal steam to start working. The high-temperature metal steam moves along the third channel 6416 and is discharged from the discharge unit 63, thus allowing it to be located inside the test tube 27, increasing the temperature and concentration of the high-temperature metal steam in the test tube 27. Then, when it is necessary to perform welding slag testing, the third adjustment unit 62 starts working, enabling the exhaust unit 65 to start exhausting. The gas discharged from the exhaust unit 65 can reduce the temperature of the high-temperature metal steam, and then the high-temperature metal steam forms welding slag, which moves with the gas. The welding slag can impact the vacuum valve, thus simulating the real welding scenario. Then, the sealing detection device on the test bench 1 is used for detection, thereby completing the life test of the vacuum valve.

[0049] The discharge section 63 includes an exhaust seat 631 fixedly connected to the installation chamber 61, a rotating rod 633 movably connected to the exhaust seat 631, a sealing block 634 disposed at the other end of the rotating rod 633, a first air inlet 632 fixedly connected to the exhaust seat 631, a drain pipe 636 disposed in the exhaust seat 631, and a partition plate 637 disposed in the exhaust seat 631; the drain pipe 636 is provided with at least two horn-shaped special tubes, wherein the special tube near the exhaust end of the exhaust seat 631 penetrates the partition plate 637, and there is a gap between the outer wall of the special tube near the exhaust end of the exhaust seat 631 and the inner wall of the drain pipe 636; a first placement cavity 635 is provided between the outer wall of the drain pipe 636 and the inner wall of the exhaust seat 631; and a communicating hole for connecting the gap and the first placement cavity 635 is provided on the drain pipe 636.

[0050] When high-temperature metal vapor needs to be discharged from the discharge section 63 and transported to the test tube 27, in order to prevent the high-temperature metal vapor from turning into welding slag and accumulating in the discharge section 63 due to the low temperature of the discharge section 63, high-temperature gas can be supplied to the first air inlet 632 by an air pump before discharge. At this time, the high-temperature gas can enter the gap through the first air inlet 632. Then, rotate the rotating rod 633 so that the sealing block 634 can move away from the drain pipe 636. At this time, the high-temperature gas can enter the gap through the connecting hole, thereby preheating the special tube and reducing the heat loss of the high-temperature metal vapor when passing through the discharge section 63, which would cause it to form welding slag and block the discharge section 63. By setting the special tube into a funnel shape, the flow rate of the high-temperature metal vapor leaving the discharge section 63 can be adjusted so that it can contact the vacuum valve, thereby increasing the temperature of the vacuum valve and completing the heat resistance test of the vacuum valve.

[0051] The steam transmission unit 64 includes an adjusting seat 643 fixedly connected to the mounting chamber 61, a second placement cavity 645, a third placement cavity 6414, and a fourth placement cavity 6415 sequentially opened in the adjusting seat 643, an inlet pipe 641 and an outlet pipe 642 disposed on the mounting chamber 61 and communicating with the second placement cavity 645, a driving component located in the second placement cavity 645, a third channel 6416 communicating with the third placement cavity 6414, and a transmission component located in the fourth placement cavity 6415; the transmission component is connected to the discharge unit 63 and is used to drive the discharge unit 63 to move, wherein the third channel 6416 is connected to the air inlet end of the drain pipe 636 through a valve and a connecting pipe;

[0052] When high-temperature metal vapor needs to be transported, it enters the second placement chamber 645 through the inlet pipe 641 and is positioned in the drive unit via the first channel 649 and the second channel 6410. The movement of the third adjusting unit 62 then positions the high-temperature metal vapor in the third placement chamber 6414. The third adjusting unit 62 then activates, causing the drive unit to move and transport the high-temperature metal vapor into the third placement chamber 6414. At this time, the valve connected to the third channel 6416 opens, allowing the high-temperature metal vapor to be discharged from the exhaust unit 63 via the third channel 6416. When the exhaust unit 65 needs to be activated... At this time, the third adjustment unit 62 starts working and the valve connected to the third channel 6416 closes. The third adjustment unit 62 drives the transmission component to start working. At this time, the high-temperature metal vapor can be discharged from the fourth placement chamber 6415. At the same time, the moving transmission component can also drive the exhaust unit 65 to move, so that the exhaust unit 65 can discharge gas and mix with the high-temperature metal vapor. At this time, the gas discharged from the exhaust unit 65 cools down the high-temperature metal vapor and cools it to form welding slag. Then, the gas carrying the welding slag can collide with the vacuum valve, thereby simulating the collision between the welding slag and the vacuum valve in the actual welding process, and completing the detection of the vacuum valve.

[0053] The third adjustment unit 62 includes a rotary handle 621 disposed on the adjustment seat 643, a rotating rod 622 connected to the rotary handle 621, and a rotary cam 623 disposed on the rotating rod 622; by moving the rotary handle 621, the position of the rotary cam 623 is adjusted to change the transport direction of the metal vapor; the rotary cam 623 is located in the third placement cavity 6414;

[0054] When the third adjustment unit 62 starts working, the rotating handle 621 is rotated. The rotating handle 621 drives the rotating cam 623 to rotate, so that the rotating cam 623 can abut against the driving component or transmission component and drive the driving component or transmission component to move, thereby completing the conveying of high temperature metal vapor.

[0055] The driving component includes a preheating seat 644 disposed in the second placement cavity 645, a second channel 6410 opened on the top of the preheating seat 644, a connector 646 screwed to the mounting chamber 61, a locking bolt 647 screwed to the connector 646, a partition tube 648 connected to the locking bolt 647, a first spring 6412 disposed in the preheating seat 644, and a first sealing rod 6413 connected to the first spring 6412; one end of the first sealing rod 6413 extends into the third placement cavity 6414; the connector 646 is provided with a first channel 649 for connecting the first placement cavity 645 and the inside and outside of the partition tube 648, and the second channel 6410 is used to connect the inside of the partition tube 648 and the preheating seat 644;

[0056] The drive unit includes two working modes. In the first mode, the third adjustment part 62 does not contact the drive unit. In this mode, high-temperature metal vapor enters the second placement chamber 645 from the air inlet pipe 641 and exits the second placement chamber 645 through the air outlet pipe 642. At this time, the high-temperature metal vapor comes into contact with the preheating seat 644, thereby increasing the temperature of the preheating seat 644 and preventing the temperature of the preheating seat 644 from being too low, which would cause the high-temperature metal vapor to form welding slag in the second channel 6410 or the first channel 649 in the preheating seat 644, thereby causing blockage of the first channel 649 or the second channel 6410.

[0057] The second operating mode is as follows: When high-temperature metal vapor needs to be discharged, the third adjusting unit 62 starts working. The moving third adjusting unit 62 drives the rotating cam 623 to rotate. At this time, the rotating cam 623 can abut against the first sealing rod 6413 and push the first sealing rod 6413 to move. At this time, the first spring 6412 deforms, and the air inlet pipe 641 is closed. The high-temperature metal vapor enters the partition pipe 648 through the first channel 649, and then enters the preheating seat 644 through the second channel 6410. Finally, the high-temperature metal vapor can enter the third placement chamber 6414. At this time, the gas can be transported to the third channel 6416, so that the high-temperature metal vapor can be discharged from the discharge section 63. Then, through the operation of the third adjustment section 62 and the valve, the rotating cam 623 abuts against the transmission component, so that the high-temperature metal vapor can be discharged from the fourth placement chamber 6415, and can drive the drive rod 6411 to move, thereby driving the exhaust section 65 to move. The moving exhaust section 65 can discharge gas and mix with the high-temperature metal vapor, thereby reducing the temperature of the high-temperature metal vapor, so that the high-temperature metal vapor can form welding slag. Then the gas can drive the welding slag to impact the vacuum valve, thereby performing the detection work of the vacuum valve.

[0058] The transmission component includes a second sealing rod 6417 movably connected to the fourth placement cavity 6415, a second spring 6418 for connecting the second sealing rod 6417 and the adjusting seat 643, and a drive rod 6411 connected to the second sealing rod 6417; the drive rod 6411 abuts against the exhaust section 65; when the transmission component needs to start working, the rotating cam 623 abuts against the second sealing rod 6417 and moves the second sealing rod 6417 away from the third placement cavity 6414, so that high-temperature metal vapor can be discharged from the fourth placement cavity 6415, and drive the drive rod 6411 to move, thereby driving the exhaust section 65 to move.

[0059] The exhaust section 65 includes a driven plate 651 movably connected to the mounting chamber 61, a fixed seat 653 fixedly installed in the mounting chamber 61, an air supply seat 654 movably connected to the fixed seat 653, a second gear 655 sleeved on the air supply seat 654, a lifting pipe 652 movably connected to the air supply seat 654, a support spring 658 for connecting the air supply seat 654 and the lifting pipe 652, a sealing gasket 657 connected to the other end of the lifting pipe 652, and an air supply pipe 656 connected to the air supply seat 654; the lifting pipe 652 has a waist-shaped hole in the circumferential direction; the output end of the lifting pipe 652 has a boss, and the driven plate 651 abuts against the bottom of the boss; the driven plate 651 is located between the drive rod 6411 and the adjusting seat 643, and the air supply seat 654 has a groove adapted to the sealing gasket 657;

[0060] Before gas delivery, the second gear 655 is rotated. The rotating second gear 655 moves the gas delivery seat 654, causing relative movement between the gas delivery seat 654 and the fixed seat 653. This changes the position of the lifting pipe 652, ensuring its highest point is in a predetermined position. Then, when the drive rod 6411 starts working, it moves the lifting pipe 652, causing the sealing gasket 657 to move away from the groove. Gas can then enter the gas delivery seat 654 through the gas delivery pipe 656, and then flow through the oblong hole... The gas enters the lifting pipe 652, enabling the exhaust section 65 to perform exhaust work. The exhaust gas mixes with high-temperature metal vapor, causing the high-temperature metal vapor to form welding slag. The gas then collides with the vacuum valve, thus completing the vacuum valve's testing. By rotating the second gear 655, the position of the lifting pipe 652 can be adjusted. When the lifting pipe 652 moves, the gap between the sealing gasket 657 and the groove can be adjusted, thereby controlling the gas flow rate and preventing excessive gas injection, which could lead to the formation of too much welding slag in the installation chamber 61 and cause blockage of the installation chamber 61.

[0061] The test assembly 2 includes a first adjustment part 22 fixedly connected to the test bench 1, a second adjustment part 23 placed perpendicularly to the first adjustment part 22, a rotary motor 24 disposed on the second adjustment part 23, a first gear 25 connected to the output end of the rotary motor 24, a gear ring 26 meshing with the first gear 25 and disposed on the second adjustment part 23, and a test tube 27 disposed on the gear ring 26. The emission assembly 6 can adjust the temperature of the metal vapor to form welding slag, which can impact the test piece 5 to complete the test. The position of the test tube 27 can be adjusted by the operation of the first adjustment part 22 and the second adjustment part 23. The operation of the rotary motor 24 causes the rotating motor 24 to drive the gear ring 26 to move through the first gear 25, so that the mounting plate at the other end of the test tube 27 can correspond to the mounting hole on the vacuum valve, thus completing the installation of the vacuum valve.

[0062] The welding slag recovery assembly 4 includes a telescopic part disposed on the test bench 1, a mounting base 42 connected to the telescopic part, a control component 41 disposed on the mounting base 42, a support frame 45 disposed on the mounting base 42, a plurality of suction nozzles 46 evenly disposed on the support frame 45, a transport pipe 47 for connecting the suction nozzles 46 and the control component 41, and a limiting component disposed on the support frame 45; the limiting component includes an adjusting cylinder 43 fixedly mounted on the support frame 45, a plurality of movable seats 49 connected to the output end of the adjusting cylinder 43, and a limiter 49 fixedly mounted on the control component 45. The moving base 49 is movably connected to a first connecting rod 411, a second connecting rod 410 movably connected to the first connecting rod 411, a hinge seat 412 disposed on the housing of the adjusting cylinder 43 and movably connected to the second connecting rod 410, and an abutment wheel 48 disposed at one end of the second connecting rod 410; the hinge seat 412 has an L-shaped structure and is also provided with a limiting plate; the control component 41 includes a housing connected to the mounting base 42, a cylinder and a negative pressure adsorber disposed in the housing, the output end of the cylinder is connected to the mounting base 42, and the negative pressure adsorber is connected to the transport pipe 47;

[0063] Because the device is equipped with a lifting component 3, the operation of the lifting component 3 can keep the vacuum valve in the closed and open state. During this process, the welding slag in the device will come into contact with the vacuum valve, which will cause the welding slag to be in the closed position of the vacuum valve, thus leading to inaccurate test results.

[0064] When the vacuum valve is opened, the cylinder adjusts the position of the mounting base 42, changing the position of the suction nozzle 46 so that the suction nozzle 46 is positioned where the vacuum valve is located, and the limiting plate abuts against the valve seat of the vacuum valve. Then, the adjusting cylinder 43 starts working, and the moving adjusting cylinder 43 drives the first connecting rod 411 to move. Then, the moving first connecting rod 411 drives the second connecting rod 410 to start working. At this time, the moving second connecting rod 410 drives the abutting wheel 48 to move, so that the abutting wheel 48 abuts against the inner wall of the vacuum valve. This completes the fixation of the position of the suction nozzle 46, preventing vibration during the suction process from causing it to collide with the vacuum valve and damage it, thus ensuring the accuracy of the test results.

[0065] Working principle explanation:

[0066] When high-temperature metal vapor needs to be discharged from the discharge section 63 and transported to the test tube 27, in order to prevent the high-temperature metal vapor from turning into welding slag and accumulating in the discharge section 63 due to the low temperature of the discharge section 63, high-temperature gas can be delivered to the first air inlet 632 by an air pump before discharge. At this time, the high-temperature gas can enter the gap through the first air inlet 632. Then, rotate the rotating rod 633 so that the sealing block 634 can move away from the drain pipe 636. At this time, the high-temperature gas can enter the gap hole through the connecting hole, thereby preheating the irregular hole.

[0067] When high-temperature metal vapor needs to be transported, it enters the second placement chamber 645 through the inlet pipe 641 and passes through the first channel 649 and the second channel 6410 to be positioned in the drive unit. The movement of the third adjusting unit 62 then positions the high-temperature metal vapor in the third placement chamber 6414. The third adjusting unit 62 then activates, causing the drive unit to move and transport the high-temperature metal vapor into the third placement chamber 6414. At this time, the valve connected to the third channel 6416 opens, allowing the high-temperature metal vapor to flow through the third channel 6416 from the outlet 6414. In step 3, when the exhaust section 65 needs to start working, the third adjustment section 62 starts working and the valve connected to the third channel 6416 closes. The third adjustment section 62 drives the transmission component to start working. At this time, the high-temperature metal vapor can be discharged from the fourth placement chamber 6415. At the same time, the moving transmission component can also drive the exhaust section 65 to move, so that the exhaust section 65 can discharge gas and mix with the high-temperature metal vapor. At this time, the gas discharged from the exhaust section 65 cools down the high-temperature metal vapor and cools it to form welding slag. Then the gas carrying the welding slag can collide with the vacuum valve.

[0068] When the third adjustment unit 62 starts working, the rotating handle 621 is rotated. The rotating handle 621 can drive the rotating cam 623 to rotate, so that the rotating cam 623 can abut against the driving component or transmission component and drive the driving component or transmission component to move, thereby completing the conveying of high temperature metal vapor.

[0069] The drive unit includes two working modes. In the first mode, the third adjustment part 62 does not contact the drive unit. In this mode, high-temperature metal vapor enters the second placement chamber 645 from the air inlet pipe 641 and exits the second placement chamber 645 through the air outlet pipe 642. At this time, the high-temperature metal vapor comes into contact with the preheating seat 644, thereby increasing the temperature of the preheating seat 644 and preventing the temperature of the preheating seat 644 from being too low, which would cause the high-temperature metal vapor to form welding slag in the second channel 6410 or the first channel 649 in the preheating seat 644, thereby causing blockage of the first channel 649 or the second channel 6410.

[0070] The second operating mode is as follows: When high-temperature metal vapor needs to be discharged, the third adjusting unit 62 starts working. The moving third adjusting unit 62 drives the rotating cam 623 to rotate. At this time, the rotating cam 623 can abut against the first sealing rod 6413 and push the first sealing rod 6413 to move. At this time, the first spring 6412 deforms, and the air inlet pipe 641 is closed. The high-temperature metal vapor enters the partition pipe 648 through the first channel 649, and then enters the preheating seat 644 through the second channel 6410. Finally, the high-temperature metal vapor can enter the third placement chamber 6414. At this time, the gas can be transported to the third channel 6416, so that the high-temperature metal vapor can be discharged from the discharge part 63. Then, through the operation of the third adjustment part 62 and the valve, the rotating cam 623 abuts against the transmission component, so that the high-temperature metal vapor can be discharged from the fourth placement chamber 6415, and can drive the drive rod 6411 to move, thereby driving the exhaust part 65 to move. The moving exhaust part 65 can discharge gas and mix with the high-temperature metal vapor, thereby reducing the temperature of the high-temperature metal vapor, so that the high-temperature metal vapor can form welding slag. Then the gas can drive the welding slag to impact the vacuum valve, thereby performing the detection work of the vacuum valve.

[0071] When the transmission component needs to start working, the rotating cam 623 abuts against the second sealing rod 6417 and moves the second sealing rod 6417 away from the third placement chamber 6414, so that the high-temperature metal vapor can be discharged from the fourth placement chamber 6415 and drive the drive rod 6411 to move, thereby driving the exhaust part 65 to move.

[0072] Before the gas supply operation, the second gear 655 is rotated. The moving second gear 655 can drive the gas supply seat 654 to move, thereby causing relative movement between the gas supply seat 654 and the fixed seat 653, changing the position of the lifting tube 652, so that the highest point of the lifting tube 652 is in a predetermined position. Then, when the drive rod 6411 starts to work, the moving drive rod 6411 can drive the lifting tube 652 to move, and then the sealing gasket 657 can move away from the groove. The gas can enter the gas supply seat 654 through the gas supply pipe 656, and then the gas can enter the lifting tube 652 through the waist-shaped hole, so that the exhaust part 65 can perform exhaust work. The exhaust gas can mix with the high-temperature metal vapor, so that the high-temperature metal vapor can form welding slag.

[0073] When the vacuum valve is opened, the cylinder adjusts the position of the mounting base 42, changing the position of the suction nozzle 46 so that the suction nozzle 46 is positioned where the vacuum valve is located, and the limiting plate abuts against the valve seat of the vacuum valve. Then, the adjusting cylinder 43 starts working, and the moving adjusting cylinder 43 drives the first connecting rod 411 to move. Then, the moving first connecting rod 411 drives the second connecting rod 410 to start working. At this time, the moving second connecting rod 410 drives the abutting wheel 48 to move, so that the abutting wheel 48 abuts against the inner wall of the vacuum valve. This completes the fixation of the position of the suction nozzle 46, preventing vibration during the suction process from causing it to collide with the vacuum valve and damage it, thus ensuring the accuracy of the test results.
