Description

Technical Field

[0001] This utility model relates to the technical field of valve performance testing equipment, specifically a valve vibration resistance testing device. Background Technology

[0002] Valves, as key control components in fluid transport systems, are widely used in many important fields such as petroleum, chemical, water conservancy, and nuclear power. In these application scenarios, valves may face complex operating conditions such as earthquakes and equipment vibrations. Their seismic performance is directly related to the operational safety and stability of the entire system. Therefore, valves must undergo rigorous seismic testing before leaving the factory.

[0003] While various valve vibration resistance testing devices exist in the current technology, they still have significant shortcomings in practical use. Some testing devices have complex structures, numerous parts, and cumbersome operation procedures, which not only increase equipment manufacturing costs but also reduce testing efficiency, hindering the rapid testing of batch valves. Some devices have unreasonable designs for valve fixing structures, making valves prone to displacement and loosening during vibration testing, leading to distorted test data that cannot accurately reflect the valve's actual vibration resistance performance. Furthermore, most existing devices are inconvenient to adjust in terms of vibration intensity and frequency, making it difficult to simulate complex vibration environments under different application scenarios, resulting in poor adaptability and inability to meet diverse testing needs.

[0004] Therefore, a valve seismic resistance testing device is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problems of existing valve vibration resistance testing devices, such as complex structure, cumbersome operation, low testing efficiency, poor testing accuracy due to unstable valve fixation and easy displacement, and inconvenient vibration intensity adjustment that cannot adapt to different working conditions.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A valve vibration resistance testing device includes a base plate, the top of the base plate is provided with four connecting mechanisms arranged in a rectangular array, the outer sides of the four connecting mechanisms are slidably connected to the same mounting plate, the top of the mounting plate is fixedly connected with two placement mechanisms arranged symmetrically front and back, the inside of the mounting plate is rotatably connected with multiple rolling mechanisms arranged symmetrically left and right, and the top of the base plate is fixedly connected with a vibration mechanism that contacts the bottom of the two rolling mechanisms;

[0009] The vibration mechanism includes a mounting frame, which is fixedly connected to the top of the base plate. A dual-axis motor is fixedly connected to the top of the mounting frame. Each output end of the dual-axis motor is fixedly connected to a camel wheel. Two fixed plates are fixedly connected to the top of the base plate and are rotatably connected to the output ends of the dual-axis motors. The outer sides of the two camel wheels are in contact with the outer side of the rolling mechanism.

[0010] The placement mechanism is used to place and secure the valve;

[0011] The four connecting mechanisms are used to limit the vertical sliding of the mounting plate and assist the mounting plate in sliding up and down.

[0012] The beneficial effects of this utility model are:

[0013] This valve vibration resistance testing device has the advantages of simple structure, convenient operation and high testing efficiency. It can firmly fix valves of different diameters and specifications, avoid valve displacement during the testing process, and ensure testing accuracy. At the same time, the vibration intensity and frequency can be changed by adjusting the speed of the dual-axis motor to adapt to the vibration resistance testing needs under different working conditions, thereby improving the practicality and adaptability of the testing device.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the top of the base plate has two rotating grooves that are adapted to two camel wheels, and the bottom of the base plate is fixedly connected to two symmetrically distributed bases.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the rotating groove provides a stable rotation space for the camel wheel, avoids interference between the camel wheel and the base plate when the camel wheel rotates, and ensures smooth operation of the vibration mechanism; the base enhances the support stability of the base plate, reduces the overall shaking of the device during the testing process, and improves the stability of the testing environment.

[0017] Furthermore, the connecting mechanism includes a limiting platform, which is fixedly connected to the top of the base plate. A slide rod that is slidably connected to the inner side of the mounting plate is fixedly connected to the top of the limiting platform. A limiting cover located above the mounting plate is fixedly connected to the top of the slide rod. The same spring located outside the slide rod is fixedly connected between the bottom of the limiting cover and the top of the mounting plate.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the slide bar provides precise guidance for the up and down sliding of the mounting plate, the limiting platform and the limiting cover together limit the sliding stroke of the mounting plate and prevent the mounting plate from slipping off the slide bar; the spring plays a buffering and reset role when the mounting plate vibrates up and down, making the vibration of the mounting plate more stable, and at the same time assisting the mounting plate to return to its position quickly, ensuring the continuity and stability of vibration detection.

[0019] Furthermore, the placement mechanism includes a base frame, which is fixedly connected to the top of the mounting plate. Two rotating blocks are fixedly connected to the top of the base frame, and a fixed shaft is fixedly connected between the two rotating blocks. A connecting block located between the two rotating blocks is rotatably connected to the outside of the fixed shaft. A top frame that is fastened to the top of the connecting block is fixedly connected to the top of the connecting block. The top frame and the base frame have the same bolt located on the opposite side of the rotating blocks. The opposite sides of the base frame and the top frame are both arc-shaped, and gaskets are fixedly connected to the opposite sides of the top frame and the base frame.

[0020] The advantages of adopting the above-mentioned further solutions are that the arc design of the base frame and top frame is adapted to the cylindrical shape of the valve, and the valve can be firmly fixed by bolt locking. The connecting block rotates around the fixed axis to facilitate quick opening and closing of the top frame and simplify the operation process. The gasket increases the friction with the valve surface, further improving the fixing effect, while avoiding scratches on the valve surface during the fixing process. In addition, the gasket can be flexibly increased or decreased according to the valve diameter to adapt to the fixing requirements of valves of different specifications.

[0021] Furthermore, the rolling mechanism includes two rolling grooves adapted to the camel wheel, and a plurality of fixed shafts distributed at equal intervals are fixedly connected inside the two rolling grooves. Rolling tubes that contact the outside of the camel wheel are rotatably connected to the outside of the plurality of fixed shafts.

[0022] The beneficial effects of adopting the above-mentioned further solution are that the shape of the rolling groove and the camel wheel are matched to ensure that the two are in close contact. The rolling tubes on the outer side of the multiple fixed shafts convert the sliding friction between the camel wheel and the rolling groove into rolling friction, which greatly reduces the friction force, reduces the wear of components, and extends the service life of the device. At the same time, it ensures the transmission efficiency of the camel wheel driving the mounting plate to vibrate up and down, making the vibration more uniform and stable.

[0023] Furthermore, the camel wheel is an eccentric wheel, and all of the gaskets are arc-shaped. The number of gaskets can be increased or decreased according to the valve diameter.

[0024] The beneficial effects of adopting the above-mentioned further solutions are that the eccentric wheel structure enables the dual-axis motor to drive the mounting plate to produce regular up-and-down vibrations when it rotates. By adjusting the speed of the dual-axis motor, the vibration frequency and intensity can be flexibly changed to simulate the vibration environment under different working conditions. The arc-shaped gasket can better fit the valve surface, improve the sealing and stability of the fixation, and the gasket addition and subtraction design expands the device's adaptability to valves of different diameters, enhancing the device's versatility.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the embodiments, by Figure 1-4 The present invention provides a valve vibration resistance testing device, comprising a base plate 1, four connecting mechanisms 2 arranged in a rectangular array on the top of the base plate 1, a mounting plate 3 slidably connected to the outer side of the four connecting mechanisms 2, two placement mechanisms 4 arranged symmetrically front and back on the top of the mounting plate 3, multiple rolling mechanisms 5 arranged symmetrically left and right on the inside of the mounting plate 3, and a vibration mechanism 6 that contacts the bottom of the two rolling mechanisms 5 fixedly connected to the top of the base plate 1.

[0032] The vibration mechanism 6 includes a mounting frame 601, which is fixedly connected to the top of the base plate 1. A dual-axis motor 602 is fixedly connected to the top of the mounting frame 601. Each output end of the dual-axis motor 602 is fixedly connected to a camel wheel 603. Two fixed plates 604 are fixedly connected to the top of the base plate 1 and are rotatably connected to the output ends of the dual-axis motor 602. The outer sides of the two camel wheels 603 are in contact with the outer side of the rolling mechanism 5.

[0033] The placement mechanism 4 is used to place and secure the valve;

[0034] Four connecting mechanisms 2 are used to limit the vertical sliding of the mounting plate 3 and assist the vertical sliding of the mounting plate 3;

[0035] The top of the base plate 1 has two rotating grooves 7 that are adapted to two camel wheels 603 respectively, and the bottom of the base plate 1 is fixedly connected to two bases 8 that are symmetrically distributed.

[0036] The rotating groove 7 provides a stable rotation space for the camel wheel 603, preventing interference between the camel wheel 603 and the base plate 1 when rotating, and ensuring smooth operation of the vibration mechanism 6; the base 8 enhances the support stability of the base plate 1, reduces the overall shaking of the device during the detection process, and improves the stability of the detection environment.

[0037] The connecting mechanism 2 includes a limiting platform 201, which is fixedly connected to the top of the base plate 1. A slide rod 202 that is slidably connected to the inner side of the mounting plate 3 is fixedly connected to the top of the limiting platform 201. A limiting cover 203 located above the mounting plate 3 is fixedly connected to the top of the slide rod 202. The same spring 204 located outside the slide rod 202 is fixedly connected between the bottom of the limiting cover 203 and the top of the mounting plate 3.

[0038] The slide bar 202 provides precise guidance for the up and down sliding of the mounting plate 3. The limiting platform 201 and the limiting cover 203 together limit the sliding stroke of the mounting plate 3 to prevent the mounting plate 3 from slipping off the slide bar 202. The spring 204 plays a buffering and reset role when the mounting plate 3 vibrates up and down, making the vibration of the mounting plate 3 more stable. At the same time, it assists the mounting plate 3 to return to its position quickly, ensuring the continuity and stability of vibration detection.

[0039] The placement mechanism 4 includes a base frame 401, which is fixedly connected to the top of the mounting plate 3. Two rotating blocks 402 are fixedly connected to the top of the base frame 401. A fixed shaft 403 is fixedly connected between the two rotating blocks 402. A connecting block 404 located between the two rotating blocks 402 is rotatably connected to the outside of the fixed shaft 403. A top frame 405 that is fastened to the top of the connecting block 404 is fixedly connected to the top of the connecting block 404. The top frame 405 and the base frame 401 are provided with the same bolt 406 located on the opposite side of the rotating blocks 402. The opposite sides of the base frame 401 and the top frame 405 are both arc-shaped. A gasket 407 is fixedly connected to the opposite sides of the top frame 405 and the base frame 401.

[0040] The arc-shaped design of the base frame 401 and top frame 405 is adapted to the cylindrical shape of the valve. The valve can be firmly fixed by locking with bolts 406. The connecting block 404 rotates around the fixed shaft 403 to facilitate quick opening and closing of the top frame 405 and simplify the operation process. The gasket 407 increases the friction with the valve surface, further improving the fixing effect, while avoiding scratches on the valve surface during the fixing process. The gasket 407 can be flexibly increased or decreased according to the valve diameter to adapt to the fixing requirements of valves of different specifications.

[0041] The rolling mechanism 5 includes two rolling grooves 501 adapted to the camel wheel 603. The interior of the two rolling grooves 501 is fixedly connected to a plurality of fixed shafts 502 that are evenly distributed. The outer sides of the plurality of fixed shafts 502 are rotatably connected to rolling tubes 503 that contact the outer side of the camel wheel 603.

[0042] The rolling groove 501 and the camel wheel 603 are matched in shape to ensure that they are in close contact. The rolling tubes 503 on the outside of the multiple fixed shafts 502 convert the sliding friction between the camel wheel 603 and the rolling groove 501 into rolling friction, which greatly reduces the friction force, reduces the wear of the components, and extends the service life of the device. At the same time, it ensures the transmission efficiency of the camel wheel 603 driving the mounting plate 3 to vibrate up and down, making the vibration more uniform and stable.

[0043] The camel wheel 603 is an eccentric wheel, and the multiple gaskets 407 are all arc-shaped. The number of gaskets 407 can be increased or decreased according to the valve diameter.

[0044] The eccentric wheel structure enables the dual-axis motor 602 to drive the mounting plate 3 to produce regular up-and-down vibrations when it rotates. By adjusting the speed of the dual-axis motor 602, the vibration frequency and intensity can be flexibly changed to simulate the vibration environment under different working conditions. The arc-shaped gasket 407 can better fit the valve surface, improving the sealing and stability of the fixture. The addition or subtraction design of the gasket 407 expands the device's adaptability to valves of different diameters and enhances the device's versatility.

[0045] Working principle:

[0046] Step 1: Place the valve to be tested on the base frame 401 of the two placement mechanisms 4, add or remove shims 407 according to the valve diameter, rotate the top frame 405 to make the connecting block 404 rotate around the fixed shaft 403 until the top frame 405 is fastened above the base frame 401, and tighten the bolts 406 to complete the valve fixing.

[0047] Step 2: Start the dual-axis motor 602. The output end of the dual-axis motor 602 drives the camel wheel 603 to rotate in the rotating groove 7. The fixed plate 604 supports and limits the output end of the dual-axis motor 602 to ensure that the camel wheel 603 rotates stably.

[0048] Step 3: When the camel wheel 603 rotates, it contacts the rolling tube 503 of the rolling mechanism 5, driving the rolling tube 503 to rotate around the fixed axis 502. At the same time, the rolling groove 501 drives the mounting plate 3 to slide up and down along the slide rod 202 of the connecting mechanism 2. The spring 204 extends and retracts with the sliding of the mounting plate 3, playing a buffering and reset role.

[0049] Step 4: After continuous vibration for a period of time, turn off the dual-axis motor 602, loosen the bolt 406, open the top frame 405 and take out the valve. Observe the structural integrity, sealing performance and other indicators of the valve to complete the seismic resistance test.
