Description

Technical Field

[0001] The invention belongs to the technical field of hardness detection, and in particular relates to a detection device for gate valve processing and a detection method thereof. Background Art

[0002] The gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance. During the production and processing of the gate plate, it is usually necessary to test its hardness. During the testing process of the existing gate plate, pressure is often applied to its surface when the gate plate is stationary for hardness testing. This cannot simulate the pressure changes that the gate plate is subjected to in actual use, which can easily lead to errors in the test results.

[0003] After searching, in the prior art, the announcement number: CN117589562A, the announcement date: 2024-02-23, discloses a gate valve hardness detection device, which relates to the field of hardness detection technology. This gate valve hardness detection device includes a workbench and a detection head arranged on a hardness tester, and the top of the workbench is connected to two symmetrically arranged L-shaped plates through a flipping mechanism. This gate valve hardness detection device can ensure the clamping effect of the gate plate, avoid loosening or even displacement during detection, and is more stable and reliable. It can also avoid deformation of the gate valve caused by excessive pressure, and ensure the accuracy of the detection. At the same time, after the gate plate is clamped and fixed, it can automatically absorb and collect impurities on its surface, making cleaning more convenient and quick, and ensuring the accuracy of the detection. During the detection, it is convenient to automatically move and flip the gate plate, so as to facilitate the detection of the upper and lower surfaces and different positions of the gate plate, making the detection more convenient and quick, and ensuring the accuracy of the detection.

[0004] However, the device still has the following defects: although it is convenient to detect the upper and lower surfaces and different positions of the gate, the detection device cannot simulate the pressure changes that the gate is subjected to in actual use, which can easily lead to errors in the detection results.

[0018] A detection method for a gate valve processing detection device, the detection method comprising:

[0019] Install the gate plate to the bottom end of the lifting assembly so that the two sets of protection mechanisms are engaged;

[0020] Open the lifting assembly to drive the gate into the interior of the two sets of protection mechanisms. The gate will stop after it drops to the preset height.

[0024] Repeat the above steps and perform hardness tests on the gate when it is lowered to different heights.

[0025] The beneficial effects of the present invention are:

[0026] 1. The second motor drives the bidirectional threaded rod to rotate and drive the two sets of protective covers to engage. The first motor drives the gate plate to enter the interior of the two sets of protective covers through the detection groove. The third motor drives the second threaded rod to rotate, so that the second internal threaded tube drives the detection mechanism to move horizontally, so that the buffer pad contacts the gate plate and squeezes it for hardness test. By simulating the movement dynamics of the gate plate during the closing process of the gate valve in actual use, the deformation of the gate plate under the preset pressure value at different descending heights is tested, so that the hardness test of the gate plate is more accurate and errors are effectively avoided.

[0027] 2. Two sets of protective covers are set up to protect the gate plate during detection to avoid splashing of debris caused by the gate plate breaking during the detection process. After the detection is completed, the second motor drives the bidirectional threaded rod to rotate in the opposite direction, so that the two sets of protective covers move in opposite directions, which is convenient for removing the gate plate and avoiding deformation of the gate plate during the detection process, which makes it difficult to remove. While improving the safety of the detection device, it reduces the difficulty of disassembly and assembly of the gate plate.

[0028] 3. By setting up multiple groups of pressure sensors, when the buffer pad squeezes the gate plate, different positions of the gate plate push the sliding shaft to move different distances under uneven conditions, resulting in different pressures on the pressure sensor. The flatness of the gate plate can be tested by comparing the pressures at different positions, and at the same time, it can be detected whether the gate plate is deformed due to pressure. The device can detect the flatness of the gate plate surface while testing the hardness of the gate plate, and can reflect the slight deformation of the gate plate during the detection process through pressure value data, thereby improving the practicality of the detection device.

[0029] 4. By setting the buffer pad and spring, the detection mechanism generates a buffer force when it contacts the gate plate, making it closer to the pressure generated by the water flow when squeezing the gate plate. At the same time, it also effectively avoids damage to the transmission mechanism caused by sudden pressure, improves the accuracy of the gate plate hardness detection, and effectively avoids wear on the gate plate during the squeezing process, and can effectively increase the service life of the detection device.

[0049] Two groups of fixed plates 8 are arranged on the base 1, and two groups of protective mechanisms 9 are arranged between the two groups of fixed plates 8. The two groups of protective mechanisms 9 are movably connected. Two groups of fixed blocks 10 are arranged on the base 1, and a second motor 11 is installed on one group of fixed blocks 10. The second motor 11 is electrically connected to the controller 5. A bidirectional threaded rod 12 is rotatably connected between the two groups of fixed blocks 10, and one end of the bidirectional threaded rod 12 is transmission-connected to the output end of the second motor 11. The bidirectional threaded rod 12 is transmission-connected to the two groups of protective mechanisms 9.

Limiting brackets 13 are arranged on both sides of the two groups of fixed plates 8, and second limiting grooves 1301 are opened on the limiting brackets 13.

[0050] The protection mechanism 9 includes a protection cover 901; illustratively, as Figure 6 shown.

[0051] The outer side wall of the protective cover 901 is fixedly connected with a linkage plate 902, and the bottom end of the linkage plate 902 is fixedly connected with a slider 903, and a third threaded hole 904 is provided on the slider 903, and the third threaded hole 904 is threadedly connected with the bidirectional threaded rod 12, and both ends of the linkage plate 902 are fixedly connected with limit bolts 905, and two groups of limit bolts 905 are movably fitted with a group of second limit grooves 1301, respectively, and a detection groove 906 is provided at the top of the protective cover 901, and the detection groove 906 is movably fitted with the gate plate, and a first slide groove 907 is provided at the top of the inner wall of the protective cover 901, and a third limit groove 908 is provided at the bottom end of the protective cover 901;

After the test is completed, the second motor 11 drives the bidirectional threaded rod 12 to rotate in the opposite direction, so that the two groups of protective covers 901 move in opposite directions, so as to facilitate the removal of the gate plate and avoid the deformation of the gate plate during the testing process and make it difficult to remove it.

[0053] For example, Figure 7 shown.

[0054] A third motor 14 is installed on one group of the fixing plates 8, and the third motor 14 is electrically connected to the controller 5. The output end of the third motor 14 is drivingly connected to the second threaded rod 15, and the second threaded rod 15 is threadedly connected to the second internally threaded barrel 16. The upper and lower ends of the second internally threaded barrel 16 are fixedly connected to the second limiting shaft 17. One group of the second limiting shafts 17 are movably fitted with the first slide groove 907, and another group of the second limiting shafts 17 penetrate the third limiting groove 908 and then movably fit with the first limiting groove 101. One end of the second internally threaded barrel 16 is fixedly connected to the detection mechanism 18, and the detection mechanism 18 is in movably conflict with the gate plate;

[0055] Specifically, the second threaded rod 15 is driven to rotate by the third motor 14, so that the second internally threaded cylinder 16 drives the detection mechanism 18 to move horizontally, contact and squeeze the gate plate, and simulate the pressure direction generated by the water flow to perform a hardness test on it. By making the two sets of second limiting shafts 17 movably fit with the first slide groove 907 and the first limiting groove 101 respectively, the second internally threaded cylinder 16 is supported while preventing it from rotating with the rotation of the second threaded rod 15.

[0056] The detection mechanism 18 includes a cylinder 1801; illustratively, as Figure 8 shown.

[0057] One end of the cylinder 1801 is transmission-connected with the second internally threaded cylinder 16, and a plurality of groups of sliding shafts 1802 are slidably connected inside the cylinder 1801, and a plurality of groups of the sliding shafts 1802 are sleeved with limiting rings 1805, and a plurality of groups of second sliding grooves 1806 and third sliding grooves 1807 are provided in the cylinder 1801, and the second sliding grooves 1806 are connected with a corresponding group of third sliding grooves 1807, and the second sliding grooves 1806 are movably fitted with the limiting rings 1805, and the The third slide groove 1807 is movably fitted with the sliding shaft 1802, a spring 1808 is arranged between the limit ring 1805 and the inner wall of the second slide groove 1806, and the spring 1808 is sleeved on the sliding shaft 1802.

[0058] Specifically, the second internal threaded cylinder 16 drives the cylinder body 1801 to move horizontally, so that the buffer pad 1804 contacts the gate plate and squeezes it, and the pressure generated by the squeezing is detected by the pressure sensor 1803, and the data is fed back to the controller 5. When the pressure value received by the gate plate reaches the preset value, the third motor 14 drives the second threaded rod 15 to move in the opposite direction, so that the detection mechanism 18 is separated from the gate plate. By setting up multiple groups of pressure sensors 1803, the pressure at different positions on the gate plate can be detected, and the flatness of the gate plate can be tested by comparing the pressure at different positions. At the same time, it can be detected whether the gate plate is deformed due to the pressure. By setting up the buffer pad 1804 and the spring 1808, the gate plate can be prevented from being worn during the squeezing process and affecting its later use.

[0059] The working principle of the gate valve processing detection device proposed by the present invention is as follows:

[0060] The gate is installed to the bottom end of the first internal threaded tube 7044 by rotating the gate bolt, and the first threaded rod 703 is driven to rotate by the first motor 702. The sliding holes 7043 provided on the two sets of limit blocks 7042 are respectively movably fitted with the two sets of first limit shafts 705 to prevent the internal thread block 7041 from rotating with the rotation of the first threaded rod 703, so that the internal thread block 7041 drives the first internal threaded tube 7044 to move up and down, thereby realizing the control of the gate's lowering height.

[0061] The bidirectional threaded rod 12 is driven to rotate by the second motor 11, so that the two sets of sliders 903 respectively drive the two sets of protective covers 901 to move in relative directions, thereby realizing the clamping connection of the two sets of protective covers 901. The gate plate is driven by the first motor 702 to enter the interior of the two sets of protective covers 901 through the detection groove 906, simulating the movement dynamics of the gate plate during the closing process of the gate valve in actual use. After the gate plate drops to a preset height, the hardness test is suspended.

[0062] The second threaded rod 15 is driven to rotate by the third motor 14, so that the second internal threaded tube 16 drives the detection mechanism 18 to move horizontally, so that the buffer pad 1804 contacts the gate plate and squeezes it, and the pressure generated by the squeezing is detected by the pressure sensor 1803, and the data is fed back to the controller 5. When the pressure value received by the gate plate reaches the preset value, the second threaded rod 15 is driven to rotate in the opposite direction by the third motor 14, so that the detection mechanism 18 is separated from the gate plate. By setting up multiple groups of pressure sensors 1803, the pressure at different positions on the gate plate can be detected, and the flatness of the gate plate can be tested by comparing the pressure at different positions. At the same time, it can be detected whether the gate plate is deformed due to the pressure. By setting up the buffer pad 1804 and the spring 1808, the gate plate can be prevented from being worn during the squeezing process and affecting its later use.

[0063] The gate plate is driven by the second motor 11 to continue moving to the next height value and then paused, and then the third motor 14 drives the detection mechanism 18 to perform hardness testing on the gate plate at this height, and this cycle is repeated to perform hardness testing on the gate plates at multiple different heights until the gate plate drops to fit with the bottom ends of the inner walls of the two sets of protective covers 901, that is, when the gate valve is simulated to be fully closed, the gate plate is subjected to a final hardness test. During the testing process, the two sets of protective covers 901 protect the gate plate being tested to avoid splashing of debris caused by the rupture of the gate plate during the testing process. After the test is completed, the second motor 11 drives the bidirectional threaded rod 12 to rotate in the opposite direction, so that the two sets of protective covers 901 move in opposite directions to facilitate the removal of the gate plate and avoid deformation of the gate plate during the testing process, which makes it difficult to remove the gate plate.

[0064] Based on the above-mentioned gate valve processing detection device, the embodiment of the present invention further proposes a detection method for the detection device. Exemplarily, the detection method includes:

[0065] Rotate the gate bolt to install the gate to the bottom end of the first internal threaded cylinder;

[0066] Turn on the second motor to drive the bidirectional threaded rod to rotate, so that the two sets of protective covers are locked together;

[0067] The first motor is turned on, and the first threaded rod rotates to drive the gate plate to enter the interior of the two sets of protective covers through the detection slot, and the gate plate is suspended after descending to a preset height;

[0068] Turn on the third motor, and the second threaded rod rotates to drive the detection mechanism to move horizontally;

[0069] The buffer pad contacts and squeezes the gate plate, and the pressure generated by the squeezing is detected by the pressure sensor, and the data is fed back to the controller;

[0070] When the pressure value received by the gate plate reaches a preset value, the third motor is turned on to drive the second threaded rod to rotate in the opposite direction, so that the detection mechanism is separated from the gate plate;

[0071] The first motor is turned on, and the first threaded rod rotates to drive the gate plate to descend to the next preset height value, and then the third motor is turned on to drive the detection mechanism to perform hardness detection on the gate plate;

[0072] Repeat the above steps to perform hardness tests when the gate is lowered to different heights, and perform the final hardness test when the gate is lowered to fit the bottom of the inner wall of the protective cover;

[0073] After the test is completed, the second motor is turned on, and the bidirectional threaded rod rotates in the opposite direction to drive the two sets of protective covers to move in opposite directions;

[0074] Turn on the first motor to drive the first internal threaded rod to rotate in the opposite direction, drive the gate plate to rise to the initial position, and remove the gate plate.
