Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to a ceramic ball core torque detection device. Background Art

[0002] With the rapid development of my country's petrochemical, coal chemical, silicon chemical, mining and metallurgy, power and environmental protection industries, and other sectors, fluid operating conditions are becoming increasingly complex and demanding, placing higher demands on valve performance. Ceramic ball valves, with their superior wear and corrosion resistance, as well as their exceptional performance in high temperatures, high pressures, and highly corrosive media, have gradually replaced traditional metal ball valves and become the preferred choice in many industrial sectors. However, the unique properties of ceramic materials, such as high hardness, brittleness, and the complexity of their internal microstructure, also present new technical challenges. Among these, the instability of the ceramic ball core's ultimate torque is particularly prominent, directly impacting the valve's service life.

[0003] Internal microcracks, residual stress or material unevenness that may exist in the ceramic ball core during the manufacturing process will lead to inconsistent mechanical properties, which in turn affects the overall reliability of the valve. If these defective ball cores flow into the valve assembly process, they will cause valve failure in subsequent use and even cause serious safety accidents. Therefore, accurate testing of the torque performance of the ceramic ball core before valve assembly has become a key link in ensuring valve quality. However, traditional testing mostly relies on surface crack detection of the ceramic ball core, which cannot effectively identify the internal microcracks, material unevenness and residual stress of the ceramic ball core, resulting in potential defects not being discovered, making the test results incomplete. At present, there is an urgent need for a high-precision, high-reliability ceramic ball core torque detection equipment that can accurately evaluate the ultimate torque of the ceramic ball core.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments. Example

[0030] like Figures 1 to 8 As shown, the present invention provides a ceramic ball core torque detection device, including a frame 1, a avoidance groove 11 is opened on the top of the frame 1, and a torque detection component 2 and a top support assembly 3 are fixedly installed on both sides of the top of the frame 1 near the avoidance groove 11, a lifting support 4 is slidably installed on the bottom of the frame 1, and the top of the lifting support 4 extends from the avoidance groove 11, a ball core 5 to be tested is placed in the lifting support 4, an expansion sleeve 6 is fixedly installed in the ball core 5 to be tested, a limiting assembly 7 for limiting the ball core 5 to be tested is fixedly installed on the top of the frame 1, a cross plate 12 is fixedly installed on the top of the frame 1, an adjustment assembly 8 for adjusting the posture of the ball core 5 to be tested is fixedly installed on the top of the cross plate 12, and a blanking assembly 9 is fixedly installed on the bottom of the frame 1.

[0031] As a further illustration of the embodiments of the present invention, problems such as internal microcracks, residual stress, or material inhomogeneity that may exist in the ceramic ball core during the manufacturing process can lead to inconsistent mechanical properties, thereby affecting the overall reliability of the valve. If these defective ball cores flow into the valve assembly process, they will cause valve failure during subsequent use and even cause serious safety accidents. The complete detection process of this device is as follows: First, a standard ball core 5 to be tested needs to be placed from the top of the lifting support 4. The ball core 5 to be tested is transported from the top to the bottom through the lifting support 4. During the transportation process, the ball core 5 to be tested first reaches the working area of the adjustment component 8. The adjustment component 8 adjusts the ball core 5 to a specific posture to facilitate subsequent detection and position limiting operations of the various components to be tested. After the adjustment is completed, the lifting support 4 continues to descend to the working area of the torque detection component 2, and the supporting component 3 is activated to move the lifting support 4 closer to the space where the torque detection component 2 is located until the output end of the torque detection component 2 extends into the ball core 5 to be tested. Then, the position limiting component 7 is activated, and the output end of the position limiting component 7 extends into the expansion sleeve 6, so that the expansion sleeve 6 is deformed, thereby fixing the ball core 5 to be tested, and then the torque detection component 2 is started until the output end of the torque detection component 2 damages the standard ball core 5 to be tested, so as to measure the limit torque of the ball core 5 to be tested and record the value, and calculate the corresponding test value based on the torque of the limit torque, and use the value as the qualified torque value of the subsequent ball core 5 to be tested. Subsequently, the torque detection component 2, the supporting component 3 and the limiting component 7 are reset to avoid interference with the ceramic ball core, and then the ceramic ball core is driven to the bottom by the lifting support 4, and the ceramic ball core is removed from the lifting support 4 by the blanking component 9 to complete the calibration of the device, and then the above process is repeated to realize the continuous torque detection operation of multiple ceramic ball cores by the device.

[0032] As a preferred solution provided by a ceramic ball core torque detection device, the torque detection component 2 includes a bracket 21 fixedly installed on the top of the frame 1, a first motor 22 is fixedly installed on the bottom of the bracket 21, a first torque sensor 23 is fixedly installed on the top of the bracket 21, a first connecting rod 231 is installed at one end of the first torque sensor 23, and a torsion rod 25 is installed at the other end of the first torque sensor 23, one end of the first connecting rod 231 and the output end of the first motor 22 are fixedly connected with a first synchronous wheel 24, and the two first synchronous wheels 24 are linked by a synchronous belt.

[0033] As a further illustration of an embodiment of the present invention, in this embodiment, after the first torque sensor 23 records the limit torque value of the ball core 5 to be tested, during subsequent torque testing, when the first torque sensor 23 detects that the first connecting rod 231 has reached the previously recorded limit torque value, the first motor 22 automatically stops operating. At this time, the torque value applied by the torsion rod 25 is the limit torque of the ball core 5 to be tested. If the ball core 5 to be tested is not damaged by the torsion resistance of the torsion rod 25, it is qualified; otherwise, it is defective. Specifically, during the testing process, a slot is provided on the side wall of the ball core 5 to be tested for entry of the torsion rod 25. The end of the torsion rod 25 extends into the slot and fits against the inner wall of the slot of the ball core 5 to be tested. When the torsion rod 25 rotates, the end of the torsion rod 25 contacts the inner wall of the ball core 5 to test the limit torque of the ball core 5 to be tested.

[0034] As a preferred solution provided by a ceramic ball core torque detection device, the limit assembly 7 includes a screw slide 71 fixedly mounted on the top of the frame 1, and a bidirectional screw 72 connected to the frame 1 is rotatably provided on one side of the screw slide 71. A limit seat 73 is fixedly mounted on the top of both ends of the screw slide 71, and a top support head 74 is fixedly mounted on the side wall of the limit seat 73. A second motor 75 and a second torque sensor 76 are fixedly mounted on the top of the frame 1. A second connecting rod 761 is mounted on one end of the second torque sensor 76, and the other end of the second torque sensor 76 is connected to the output end of the second motor 75. One end of the second connecting rod 761 and the end of the bidirectional screw 72 are fixedly connected with a second synchronous wheel 77. The two second synchronous wheels 77 are linked by a synchronous belt, and the second motor 75 drives the screw slide 71 to drive the two top support heads 74 to move closer to or away from each other.

[0035] As a further illustration of an embodiment of the present invention, in this embodiment, the bidirectional screw 72 of the limiting assembly 7, driven by a second motor 75, is linked to the synchronous belt via a second synchronous pulley 77, causing the limiting seats 73 at both ends to approach each other. The supporting head 74 moves with the limiting seat 73 and extends into the interior of the expansion sleeve 6. By applying force symmetrically, the expansion sleeve 6 is uniformly expanded, thereby securing the ball core 5 to be tested. A second torque sensor 76 monitors the driving torque of the bidirectional screw 72 in real time to prevent excessive supporting force from damaging the expansion sleeve 6 or the ball core. Through bidirectional limiting and torque feedback control, the deformation of the expansion sleeve 6 is ensured to be controllable, avoiding ball core deflection or stress concentration due to unilateral force.

[0036] As a preferred solution provided by a ceramic ball core torque detection device, the lifting support 4 includes two bracket plates 411, which are fixedly connected by multiple support rods 412, and a screw 413 is rotatably connected between the two bracket plates 411. A lifting plate 41 is threadedly installed on the screw 413, and the lifting plate 41 is slidingly connected to the multiple support rods 412. A third motor 42 is provided on the top of the upper bracket plate 411 for driving the lifting plate 41 to rise and fall. A ball core support 43 for limiting the ball core 5 to be tested is fixedly installed on the lifting plate 41, and a vertical plate 44 for cooperating with the top support assembly 3 is fixedly installed on one side of the lifting plate 41.

[0037] As a further illustration of an embodiment of the present invention, in this embodiment, the ball core support 43 employs an arcuate groove structure that fits against the outer surface of the ball core 5 to be tested, preventing the ball core 5 from rolling during the lifting process. Furthermore, the ball core 5 to be tested is confined within the ball core support 43, facilitating adjustment of the posture of the ball core 5 to be tested by the adjustment assembly 8. Conventional ceramic ball cores in commercially available automatic valves have sidewalls with perforations for access by the output of the ball valve controller. Vertical plates 44 cooperate with the support assembly 3 to achieve fine-tuning of the horizontal displacement of the lifting support 4, ensuring that the torsion rod 25 extends into the ball core 5 along the sidewall opening of the ball core 5 to be tested. By twisting the torsion rod 25 through the sidewall opening of the ball core 5 to be tested, a torque test is performed on the ball core 5 to be tested.

[0038] As a preferred solution provided by a ceramic ball core torque detection device, the blanking assembly 9 includes a first cylinder 91 fixedly installed at the bottom of the frame 1, a protrusion 92 is formed on the bracket plate 411 at the bottom of the lifting support 4, and an opening is provided on the lifting plate 41 for the protrusion 92 to pass through. A slide 93 for guiding the rolling direction of the ball core 5 to be tested is fixedly installed on one side of the bottom of the lifting support 4.

[0039] As a further illustration of an embodiment of the present invention, in this embodiment, after the test is completed, the third motor 42 drives the lifting plate 41 to move the ball core 5 to be tested downward to the bottom of the lifting support 4. The protrusion 92 at the bottom of the lifting support 4 pushes the ball core 5 upward along the opening, allowing the ball core 5 to be tested to separate from the ball core support 43. At this time, the first cylinder 91 is activated, and the output end of the first cylinder 91 pushes the side wall of the ball core 5 to be tested, causing the ball core 5 to roll out along the slide 93. The slide 93 has an inclined angle and a smooth surface, ensuring that the ball core slides to the designated area without collision, avoiding surface scratches that may be caused by traditional pneumatic grippers. It is particularly suitable for non-destructive unloading of brittle ceramic materials.

[0040] As a preferred solution provided by a ceramic ball core torque detection device, a cross bar 13 and two guide rods 14 are fixedly installed at the bottom of the frame 1, and the cross bar 13 and the two guide rods 14 both pass through the bottom of the lifting support 4. A spring 15 is sleeved on the cross bar 13, and the two ends of the spring 15 are respectively pressed against the side walls of the bottom of the frame 1 and the side walls of the bottom of the lifting support 4.

[0041] As a further illustration of an embodiment of the present invention, in this embodiment, the crossbar 13 and guide rod 14 form a sliding track for the lifting support 4. A spring 15 keeps the lifting support 4 away from the torsion rod 25, preventing the torsion rod 25 from interfering with the travel path of the lifting plate 41. Only by the support assembly 3 cooperating with the vertical plate 44 can the lifting support 4 be pushed toward the torsion rod 25, ensuring that the torsion rod 25 can only contact the ball core 5 under test during torque testing.

[0042] As a preferred solution provided by a ceramic ball core torque detection device, the adjustment component 8 includes a plurality of mounting seats 81 fixedly mounted on the top of the cross-plate 12. A passage groove 121 is opened on the top of the cross-plate 12 for the lifting support 4 to pass through. The plurality of mounting seats 81 are distributed along the periphery of the passage groove 121. A second cylinder 82 is fixedly mounted on the side wall of each mounting seat 81. The output end of the second cylinder 82 passes through the side wall of the mounting seat 81 and is fixedly connected to an opening plate 83. An adjusting wheel 84 is rotatably mounted in each opening plate 83. All relative adjusting wheels 84 are arranged perpendicular to each other. A fourth motor 85 for driving the adjusting wheel 84 to rotate is fixedly mounted on the top of the opening plate 83.

[0043] As a further illustration of an embodiment of the present invention, in this embodiment, the second cylinder 82 of the adjustment assembly 8 drives the opening plate 83 to move horizontally, causing the adjustment wheel 84 to contact the outer surface of the core 5 to be tested. The core 5 to be tested is also restrained by the core support 43 and does not move due to the interference of the adjustment wheel 84. The fourth motor 85 drives the adjustment wheel 84 to rotate, and the friction between the adjustment wheel 84 and the core 5 to be tested adjusts the circumferential angle of the core 5 to be tested. The two sets of opposing adjustment wheels 84 are arranged perpendicular to each other. When the adjustment wheel 84 on one side rotates the core 5 to be tested, the adjustment wheel 84 on the other side can compensate for the rotation restriction of the adjustment wheel 84 on one side, allowing the adjustment assembly 8 to have a wider range of correction angles. The mounting seats 81 are evenly distributed along the circumference of the through slot 121, enabling posture correction of the core 5 to be tested in multiple degrees of freedom. Through multi-directional coordinated adjustment, the installation posture of the core 5 to be tested is ensured to be strictly aligned with the force applied by the torque detection component 2, reducing detection errors caused by angular deviation. In addition, a monitor (not shown in the figure) is provided on the top of the mounting seat 81. Through multi-directional monitoring of the monitors at various angles, the initial posture of the ball core 5 to be tested that enters the adjustment component 8 is scanned and uploaded to an external intelligent device for analysis. Corresponding instructions are issued to the fourth motor 85 and the second cylinder 82 through manual or intelligent equipment to ensure that the ball core 5 to be tested can enter the work station of the torque detection component 2 in a specific posture. Specifically, the flow direction of the flow channel in the ball core 5 to be tested is adjusted to be aligned with the top support head 74 through the adjustment component 8, and the perforation on the side wall of the ball core 5 to be tested is aligned with the torsion rod 25, which is a specific posture.

[0044] As a preferred solution provided by a ceramic ball core torque detection device, the support assembly 3 includes a right-angle seat 31 fixedly installed on the top of the frame 1, and a third cylinder 32 is fixedly installed on the side wall of the right-angle seat 31. The output end of the third cylinder 32 passes through the side wall of the right-angle seat 31 and is fixedly connected to a support disc 33.

[0045] As a further illustration of an embodiment of the present invention, in this embodiment, the vertical support surface of the right-angle seat 31 provides a stable support force, ensuring that the supporting force of the supporting disc 33 is transmitted in the horizontal direction, thereby preventing the lifting support 4 from tilting during movement.
