Description

Technical Field

[0001] The present invention relates to the technical field of valve pressure testing, and in particular to an intelligent valve pressure detection device. Background Art

[0002] Smart valves are commonly used opening and closing components for gas or liquid transportation. According to their structure, they can be divided into gate valves, globe valves, check valves, plug valves, ball valves, butterfly valves, diaphragm valves, etc. Valves have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, overflow and pressure relief. They are widely used in oil processing stations, long-distance pipelines, chemical industries, etc. When the conveying medium is toxic, harmful, flammable, or explosive, if there are problems with the sealing or material of the valve, it is easy to cause media leakage or even explosion, which will pose a serious threat to the safe operation of the equipment and the safety of personnel. Therefore, valve pressure performance testing is crucial, including shell strength testing and sealing testing.

[0003] During the valve testing process, the valve sealing and shell strength are usually tested separately. When performing the sealing and shell strength tests separately, different test equipment needs to be used. When switching equipment, it is necessary to reconnect the pipeline, calibrate the equipment, and install and remove the valve multiple times. This not only increases the test time and workload, causes operator fatigue, and increases the probability of error, but also multiple installation and removal will cause the installation position and connection method of the valve to change, and it is easy for the valve to be installed loosely, resulting in leakage during the sealing test, thereby affecting the accuracy of the test results. In addition, since the sealing and shell strength tests are performed at different times, it is difficult to integrate the test data. The data of the sealing test and the shell strength test need to be recorded and analyzed separately, which increases the complexity of data management.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present invention provides an intelligent valve pressure detection device with the following beneficial effects:

[0020] 1. Through the set pressure detection mechanism, when driving the mobile frames on both sides to drive the connecting pipe close to the valve body for sealing detection, the pressure plate can be synchronously driven to press the valve body shell to detect the strength of the valve body shell. This can not only significantly improve the detection efficiency, reduce the time for equipment switching and installation and disassembly, improve the accuracy of the test results, and reduce the impact of valve body installation errors, but also reduce the difficulty of valve body detection data integration and analysis, improve the convenience of data management, and by completing two tests on the valve body at the same position, the number of valve body installation and disassembly is reduced, the operator fatigue is reduced, and the sealing problems of the valve body caused by multiple installation and disassembly are avoided.

[0021] 2. By setting the fixed plate, fixed column, linkage plate and connecting column, the movable frames on both sides can be pulled synchronously to drive the connecting pipes closer to each other, so that the pressure plates on both sides can evenly apply pressure to the valve body shell. This not only avoids deformation or damage of the valve body shell due to excessive or insufficient pressure on one side, ensuring the accuracy of the valve body shell strength test results, but also uniform pressure can reduce local stress concentration on the valve body shell, avoid structural damage caused by local overload, and extend the service life of the valve body.

[0022] 3. Through the leakage detection mechanism set up, after the connecting pipe and the two ends of the valve body are connected, the circular ring connected on the side wall of the connecting pipe can be continued to be pushed close to the side wall of the valve body, so that the rubber sealing ring connected on the side wall of the circular ring and the side wall of the valve body are squeezed and fitted with each other. This not only can quickly form a closed space at the connection between the connecting pipe and the valve body, reducing the preparation time before valve body inspection and improving the overall efficiency of inspection, but also reduces the risk of leakage caused by poor sealing, ensures the stability of pressure during the inspection process, and improves the accuracy of the inspection results.

[0023] 4. By providing the first piston rod, the first hollow column and the pull plate, after a closed space is formed at the connection between the connecting pipe and the valve body, the air in the space can be sucked into the first hollow column, so that a negative pressure is formed in the closed space. This not only allows the rubber sealing ring to be more closely adsorbed and fitted to the side wall of the valve body, further enhancing the sealing effect and ensuring that there is no tiny gap between the sealing ring and the side wall of the valve body, thereby effectively preventing leakage, but also enables the rubber sealing ring to better adapt to the irregular surface of the side wall of the valve body, ensuring the consistency of the sealing effect. Even if there are tiny unevenness on the surface of the valve body, the negative pressure adsorption can ensure that the sealing ring fits tightly.

[0024] Among them, through the provision of the second hollow column, the second piston rod and the disc, when leakage occurs at the connection between the connecting pipe and the valve body, the second piston rod can be automatically pushed out from the inside of the second hollow column, driving the disc and the button to separate, turning off the display light, and promptly reminding the staff that leakage occurs during the valve body sealing test. This not only ensures that leakage problems are discovered in time during the test process, avoiding further damage caused by delayed discovery, reducing misjudgment, and ensuring the accuracy and reliability of the test results, but also reduces repeated testing due to leakage, avoids unnecessary repeated operations, saves time, and improves test efficiency.

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all 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.

[0039] An intelligent valve pressure detection device according to this embodiment, such as Figure 1 - Figure 8As shown, it includes a detection box 1 and a valve body 2, a support plate 8 is fixedly connected to the inside of the detection box 1, and the valve body 2 is placed on the upper end surface of the support plate 8, and support columns 3 are symmetrically fixedly connected on both sides of the inside of the detection box 1, and a movable frame 4 is slidably connected between the outer surfaces of the two support columns 3 on the same side, and a connecting pipe 5 is passed through and fixedly connected to the movable frame 4, and also includes a pressure detection mechanism and a leakage detection mechanism, the pressure detection mechanism includes symmetrically arranged pressure plates 601, which are respectively arranged on both sides of the valve body 2, and the pressure plates 601 are fixedly connected to the telescopic columns 602 on the side away from the valve body 2, and the telescopic columns 602 are fixedly connected to the inner wall of the detection box 1, and the pressure plates 601 are symmetrically fixedly connected to the connecting plates 607 on the side close to the telescopic columns 602, and the connecting plates 607 are rotatably connected with elastic telescopic plates 606, and the ends of the elastic telescopic plates 606 away from the connecting plates 607 are rotatably connected to the side walls of the movable frame 4, and the pressure detection mechanism is used to apply pressure to the outer shell of the valve body 2 when the connecting pipe 5 and the valve body 2 are close to each other.

[0040] In this embodiment, Figure 2 and Figure 3 As shown, the elastic telescopic plate 606 includes a hollow plate 6061 and an extension plate 6062. The extension plate 6062 is slidably connected to the hollow plate 6061. A first spring 6063 is fixedly connected between the extension plate 6062 and the inside of the hollow plate 6061. The hollow plate 6061 is rotatably connected to the side wall of the movable frame 4. The extension plate 6062 is rotatably connected to the upper end surface of the connecting plate 607. When the elastic telescopic plate 606 is limited during continuous movement, the extension plate 6062 will slide into the inside of the hollow plate 6061 and squeeze the first spring 6063.

[0041] In this embodiment, Figure 1 As shown, the pressure plate 601 is fixedly connected to the center of one side near the valve body 2 with a pressure sensor 603, and a display screen 604 is electrically connected between the two pressure sensors 603. The display screen 604 is fixedly connected to the side wall of the detection box 1. When the pressure plate 601 presses the valve body 2, the applied pressure will be transmitted to the display screen 604 through the pressure sensor 603 for display.

[0042] In this embodiment, Figure 4 and Figure 5As shown, a connecting shaft 614 is rotatably connected to the center of the lower end surface of the support plate 8, and a fixed plate 609 is fixedly connected to the outer surface of the connecting shaft 614. A fixed column 615 is symmetrically fixedly connected to the upper end surface of the fixed plate 609. The outer surfaces of the fixed columns 615 are rotatably connected to the linkage plate 610, and the linkage plates 610 are rotatably connected to the connecting columns 611 at one end away from the fixed columns 615. The connecting columns 611 are fixedly connected to the lower end surface of the movable frame 4. When the connecting shaft 614 rotates on the lower end surface of the support plate 8, the fixed plate 609 can pull the fixed columns 615 to move synchronously, so that the fixed columns 615 pull one end of the linkage plate 610 to rotate with the connecting shaft 614 as the center of the circle. When one end of the linkage plate 610 is subjected to tension, the linkage plate 610 will pull the movable frames 4 on both sides closer to each other through the connecting columns 611.

[0043] In this embodiment, Figure 5 As shown, the lower end of the connecting shaft 614 is fixedly connected to the second bevel gear 613, and the second bevel gear 613 is meshedly connected to the first bevel gear 612. The first bevel gear 612 is fixedly connected to the rotating shaft 608, and the rotating shaft 608 is connected to the detection box 1 through rotation. The end of the rotating shaft 608 away from the first bevel gear 612 is fixedly connected to the drive motor 605, and the drive motor 605 is fixedly connected to the side wall of the detection box 1. When the drive motor 605 is turned on to drive the rotating shaft 608 to rotate, the first bevel gear 612 and the second bevel gear 613 are meshed and connected, which can drive the connecting shaft 614 to rotate synchronously on the lower end surface of the support plate 8.

[0044] In the prior art, different test equipment is required to perform sealing and shell strength tests respectively. When switching equipment, it is necessary to reconnect the pipeline, calibrate the equipment, and install and remove the valve multiple times. This not only increases the test time and workload, causes operator fatigue, and increases the probability of error, but also multiple installation and removal will cause the installation position and connection method of the valve to change, which is prone to leakage during the sealing test due to the valve being not installed firmly, thereby affecting the accuracy of the test results. In addition, since the sealing and shell strength tests are performed at different times, it is difficult to integrate the test data. The data of the sealing test and the shell strength test need to be recorded and analyzed separately, which increases the data The complexity of management is reduced. Compared with the existing technology, in the process of driving the movable frames 4 on both sides to drive the connecting pipe 5 to approach the valve body 2 for sealing detection, the pressure plate 601 can be synchronously driven to press the outer shell of the valve body 2 to detect the strength of the outer shell of the valve body 2. This can not only significantly improve the detection efficiency, reduce the time for equipment switching and installation and disassembly, improve the accuracy of the detection results, and reduce the impact of the installation error of the valve body 2, but also reduce the difficulty of valve body 2 detection data integration and analysis, improve the convenience of data management, and by completing two tests on the valve body 2 at the same position, the number of installation and disassembly of the valve body 2 is reduced, the operating fatigue is reduced, and the sealing problems of the valve body 2 caused by multiple installation and disassembly are avoided.

[0045] In other aspects, this embodiment also provides a leakage detection mechanism for detecting the connection sealing between the connecting pipe 5 and the valve body 2, such as Figure 1 、 Figure 2 、 Figure 6 - Figure 8 As shown, the leakage detection mechanism includes a ring 701, which is slidably connected to the connecting pipe 5. The side of the ring 701 away from the movable frame 4 is fixedly connected to a rubber sealing ring 704, and the side of the ring 701 away from the rubber sealing ring 704 is symmetrically fixedly connected to a sliding column 712. The sliding columns 712 are all slidably connected to the connecting pipe 5.

[0046] In this embodiment, Figure 8 As shown, the end of the sliding column 712 away from the ring 701 is fixedly connected to the limit plate 713, and the side of the limit plate 713 close to the connecting pipe 5 is fixedly connected to the second spring 714. The end of the second spring 714 away from the limit plate 713 is fixedly connected to the side wall of the connecting pipe 5. The second spring 714 is sleeved on the outer surface of the sliding column 712. When the sliding column 712 slides out from the inside of the connecting pipe 5, it will push the limit plate 713 away from the connecting pipe 5 and pull the second spring 714 to extend.

[0047] In this embodiment, Figure 6As shown, a first hollow column 702 is fixedly connected to the upper surface of the circular ring 701, a first piston rod 705 is slidably connected to the upper end of the first hollow column 702, and a pull plate 703 is fixedly connected to the upper end of the first piston rod 705. When the pull plate 703 is pulled to drive the first piston rod 705 to rise, the first piston rod 705 will be driven to slide out from the inside of the first hollow column 702, and the air inside the circular ring 701 will be sucked into the first hollow column 702.

[0048] In this embodiment, Figure 7 As shown, a second hollow column 706 is fixedly connected to the circular ring 701, a second piston rod 707 is slidably connected to the second hollow column 706, and a disc 708 is fixedly connected to the end of the second piston rod 707 away from the second hollow column 706. A support block 709 is fixedly connected to the outer surface of the circular ring 701 near the disc 708, a display light 710 is fixedly connected to the upper end surface of the support block 709, and a button 711 is fixedly connected to the lower end surface of the support block 709. The button 711 and the disc 708 are at the same height. The button 711 and the display light 710 are electrically connected. When the air inside the second hollow column 706 is extracted, the second piston rod 707 will be pulled into the second hollow column 706, and the disc 708 will be moved to the button 711 to press the button 711, turning on the display light 710 to work. Conversely, when air enters the second hollow column 706, the second piston rod 707 will be pushed to slide out of the second hollow column 706, driving the disc 708 and the button 711 to separate, turning off the display light 710.

[0049] Compared with the prior art, after the connecting tube 5 and the valve body 2 are connected at both ends, the circular ring 701 connected to the side wall of the connecting tube 5 can be continued to be pushed close to the side wall of the valve body 2, so that the rubber sealing ring 704 connected to the side wall of the circular ring 701 and the side wall of the valve body 2 are squeezed and fitted with each other, which not only can quickly form a closed space at the connection between the connecting tube 5 and the valve body 2, reducing the preparation time before the inspection of the valve body 2 and improving the overall efficiency of the inspection, but also reduces the risk of leakage caused by poor sealing, ensures the stability of pressure during the inspection process, and improves the accuracy of the inspection results.

[0050] The working process and principles involved in the overall content of the above embodiment are as follows:

[0051] It should be noted that a sealing structure is provided between the first hollow column 702 and the first piston rod 705 and between the second hollow column 706 and the second piston rod 707. Please refer to the extraction of the syringe in the prior art and no further explanation will be given here.

[0052] When the staff needs to inspect the valve body 2, they first place the valve body 2 above the support plate 8, and then turn on the drive motor 605 to drive the rotating shaft 608 to rotate on the detection box 1, and drive the rotating shaft 608 away from the first bevel gear 612 connected to one end of the drive motor 605 to rotate. During the rotation of the first bevel gear 612, the first bevel gear 612 will be meshed with the second bevel gear 613 to drive the connecting shaft 614 connected to the second bevel gear 613 to rotate synchronously on the lower end surface of the support plate 8. Since the outer surface of the connecting shaft 614 is connected to the fixed plate 609, the upper end surface of the fixed plate 609 is connected to the fixed column 615, and the outer surface of the fixed column 615 is rotatably connected to the linkage plate 610, and the linkage plate 610 is The connecting column 611 is rotatably connected to the lower end surface of the movable frame 4. Therefore, as the connecting shaft 614 rotates, the fixed plate 609 and the fixed column 615 can pull one end of the linkage plates 610 on both sides to move synchronously with the connecting shaft 614 as the center. At this time, when one end of the linkage plate 610 is subjected to tension, it will pull the movable frame 4 to slide closer to each other on the outer surface of the support column 3 through the connecting column 611, driving the connecting pipe 5 connected to the movable frame 4 to contact the two ends of the valve body 2. In the process of the movable frame 4 approaching the valve body 2, the movable frame 4 will push the elastic expansion plates 606 connected to the rotation on both sides to move synchronously horizontally, so that the elastic expansion plates 606 move from an inclined state to a horizontal state. As the state of the elastic expansion plates 606 changes, the elastic expansion plates 60 6 will push the pressure plate 601 horizontally close to the outer shell of the valve body 2 through the connecting plate 607 that is rotated away from one end of the movable frame 4, and at the same time pull the telescopic column 602 connected to the pressure plate 601 to extend. After the pressure plate 601 contacts the outer shell of the valve body 2, as the movable frame 4 continues to push one end of the hollow plate 6061 to move, the pressure plate 601 cannot move further, and the extension plate 6062 will slide into the interior of the hollow plate 6061, squeezing the first spring 6063 connected between the extension plate 6062 and the interior of the hollow plate 6061. The rebound force of the gradually contracting first spring 6063 acts on the extension plate 6062, which will cause the extension plate 6062 to push the connecting block, driving the pressure plate 601 to press the outer shell of the valve body 2. The pressure of the pressure plate 601 squeezing the outer shell of the valve body 2 gradually increases, and the pressure sensor 603 connected to the pressure plate 601 will display the squeezing force of the pressure plate 601 on the display screen 604 to detect the strength of the outer shell of the valve body 2. At the same time, the movable frame 4 will drive the connecting pipe 5 to contact the valve body 2 to detect the sealing of the valve body 2. This can not only significantly improve the detection efficiency, reduce the time for equipment switching and installation and disassembly, improve the accuracy of the detection results, and reduce the influence of the installation error of the valve body 2, but also reduce the difficulty of integrating and analyzing the detection data of the valve body 2, improve the convenience of data management, and by completing two tests on the valve body 2 at the same position, reduce the number of installation and disassembly of the valve body 2, and reduce operator fatigue.Avoid the sealing problem of the valve body 2 caused by multiple installation and disassembly, and drive the connection pipe 5 and the two ends of the valve body 2 to perform sealing detection;

[0053] During the synchronous horizontal approach of the two side movable frames 4, the pressure plates 601 on both sides can evenly apply pressure to the outer shell of the valve body 2, which not only avoids deformation or damage of the outer shell of the valve body 2 due to excessive or insufficient pressure on one side, thereby ensuring the accuracy of the strength test results of the outer shell of the valve body 2, but also the even pressure can reduce local stress concentration on the outer shell of the valve body 2, avoid structural damage caused by local overload, and extend the service life of the valve body 2.

[0054] When the cam 711 is in the closed position, the spring 712 of the cam 712 is in the closed position, and the spring 712 of the cam 712 is in the closed position, so that the cam 712 of the cam 712 is in the open position, and the spring 712 of the cam 712 is in the open position, so that the cam 712 of the cam 712 is in the open position, and the cam 712 of the cam 712 is in the open position, so that the cam 712 of the cam 712 is in the open position, and the cam 712 of the cam 712 is in the open position, so that the cam 712 of the cam 712 is in the open position, and the cam 712 of the cam 712 is in the open position, so that the cam 712 of the cam 712 is in the open position, and the cam 712 of the cam 712 is in the open position,

[0055] After the movable frame 4 drives the connecting pipe 5 to move to the designated position, the staff can pull the pull plate 703 upwards to drive the first piston rod 705 to slide out from the first hollow column 702. At this time, the air in the closed space formed inside the ring 701 will be sucked into the first hollow column 702, which can not only make the rubber sealing ring 704 more closely adsorbed and fitted to the side wall of the valve body 2, further enhancing the sealing effect and ensuring that there is no tiny gap between the sealing ring and the side wall of the valve body 2, thereby effectively preventing leakage, but also enable the rubber sealing ring 704 to better adapt to the irregular surface of the side wall of the valve body 2, ensuring the consistency of the sealing effect. Even if there are tiny unevenness on the surface of the valve body 2, negative pressure adsorption can ensure that the sealing ring fits tightly.

[0056] When the air in the enclosed space is sucked into the first hollow column 702, the air in the second hollow column 706 will be extracted synchronously, pulling the second piston rod 707 to slide into the second hollow column 706, driving the second piston rod 707 away from the disc 708 connected to one end of the second hollow column 706 to move to the bottom of the support block 709, pressing the button 711 connected to the lower end of the support block 709, turning on the indicator light 710 connected to the upper end of the support block 709 to work, and when the connection between the connecting pipe 5 and the valve body 2 leaks during the sealing test, the enclosed space inside the ring 701 will be The gas enters and enters the second hollow column 706, pushing out the second piston rod 707 inside the second hollow column 706, driving the disc 708 and button 711 connected to the second piston rod 707 to separate, turning off the display light 710, and promptly reminding the staff that leakage occurs during the sealing test of the valve body 2. This not only ensures that leakage problems are discovered in time during the test process, avoiding further damage caused by delayed discovery, reducing misjudgment, and ensuring the accuracy and reliability of the test results, but also reduces repeated tests caused by leakage, avoids unnecessary repeated operations, saves time, and improves test efficiency.
