Description

Technical Field

[0001] This utility model relates to the field of valve group instrument testing, and in particular to a valve group instrument testing device. Background Technology

[0002] In the field of valve group instrumentation technology, pressure valve instruments are core monitoring equipment in industrial production and energy management. They play a key role in scenarios such as pressure monitoring of petrochemical pipelines, safety control of boilers in power systems, and water pressure management of building central air conditioning. Therefore, accurate testing of them is of utmost importance.

[0003] Currently, testing devices for pressure valves and instruments generally rely on manual clamping for fixation. This manual operation is not only inefficient but also makes it difficult to ensure uniform clamping force each time, which can easily cause the pressure valves and instruments to loosen during testing, thus affecting the accuracy of test data such as pressure parameters. Furthermore, existing devices have poor design in terms of power transmission and the coordinated operation of clamping components. The clamping operation for pressure valves and instruments is complex and has significant power loss, resulting in time-consuming and labor-intensive preparation work before testing, which greatly increases testing costs and time. To solve the above problems, we propose a valve assembly instrument testing device. Utility Model Content

[0004] The main purpose of this utility model is to provide a valve group instrument testing device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A valve assembly instrument testing device includes a support table and a pressure valve instrument. The pressure valve instrument is located at the upper end of the support table. Base legs are fixedly connected to the four corners of the lower end of the support table. A mounting plate is fixedly connected to the four base legs. A first clamping assembly and a second clamping assembly are provided at the upper end of the mounting plate. Both the first clamping assembly and the second clamping assembly are located on the outside of the pressure valve instrument. A snap-fit ​​block is fixedly connected to the outside of the pressure valve instrument. A snap-fit ​​groove is formed at the upper end of the support table, and the lower end of the snap-fit ​​block is located inside the snap-fit ​​groove.

[0006] Preferably, a drive motor is fixedly mounted on the upper end of the mounting plate, and a drive wheel is fixedly connected to the output end of the drive motor. The drive wheel is located at the lower end of the mounting plate, and a belt is sleeved on the outer side of the drive wheel. A driven wheel is sleeved on the inner side of the other end of the belt. A first transmission gear is fixedly connected to the upper end of the driven wheel, and the first transmission gear is rotatably connected to the upper end of the mounting plate.

[0007] Preferably, the first clamping assembly includes a first main clamping block and a first secondary clamping block. The first main clamping block and the first secondary clamping block are respectively disposed on the outer side of one end of the pressure valve instrument, and both the first main clamping block and the first secondary clamping block are slidably connected to the support table. A first main bidirectional toothed belt is fixedly connected to the lower end of the first main clamping block, and a first secondary bidirectional toothed belt is fixedly connected to the lower end of the first secondary clamping block. Both the first main bidirectional toothed belt and the first secondary bidirectional toothed belt are slidably connected to the upper end of the mounting plate, and one side of the first main bidirectional toothed belt meshes with the outer side of the first transmission gear.

[0008] Preferably, the second clamping assembly includes a second main clamping block and a second slave clamping block. The second main clamping block and the second slave clamping block are located on the outer side of the other end of the pressure valve instrument, and the second main clamping block and the second slave clamping block are slidably connected to the support table. A second main bidirectional toothed belt is fixedly connected to the lower end of the second main clamping block, and a second slave bidirectional toothed belt is fixedly connected to the lower end of the second slave clamping block. The second main bidirectional toothed belt and the second slave bidirectional toothed belt are both slidably connected to the upper end of the mounting plate, and the second main bidirectional toothed belt meshes with the outer side of the first transmission gear.

[0009] Preferably, the lower ends of the first main bidirectional toothed belt, the second main bidirectional toothed belt, the first secondary bidirectional toothed belt, and the second secondary bidirectional toothed belt are all fixedly connected to sliders, and the upper end of the mounting plate is provided with a groove corresponding to the slider, and the slider is slidably connected to the inner side of the groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This valve assembly instrument testing device, by inserting the clamping block on the pressure valve instrument into the clamping groove, can complete the initial positioning.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-6 As shown, a valve group instrument testing device includes a support table 1 and a pressure valve instrument 3. The pressure valve instrument 3 is located at the upper end of the support table 1. The four corners of the lower end of the support table 1 are fixedly connected to the base legs 2. The four base legs 2 are fixedly connected to each other. The upper end of the mounting plate 6 is provided with a first clamping component and a second clamping component. The first clamping component and the second clamping component are both located on the outside of the pressure valve instrument 3. The outside of the pressure valve instrument 3 is fixedly connected to a snap-fit ​​block 4. The upper end of the support table 1 is provided with a snap-fit ​​groove 5. The lower end of the snap-fit ​​block 4 is located on the inside of the snap-fit ​​groove 5.

[0017] In this embodiment, a drive motor 7 is fixedly installed on the upper end of the mounting plate 6, and a drive wheel 8 is fixedly connected to the output end of the drive motor 7. The drive wheel 8 is located at the lower end of the mounting plate 6. A belt 9 is sleeved on the outer side of the drive wheel 8, and a driven wheel 10 is sleeved on the inner side of the other end of the belt 9. A first transmission gear 11 is fixedly connected to the upper end of the driven wheel 10, and the first transmission gear 11 is rotatably connected to the upper end of the mounting plate 6.

[0018] Specifically, firstly, the pressure valve instrument 3 is inserted into the snap-fit ​​groove 5 at the upper end of the support table 1 through the snap-fit ​​block 4 on its outer side to complete the initial positioning and installation. Then, the drive motor 7 is started. The output end of the drive motor 7 will drive the drive wheel 8 to rotate. The drive wheel 8 transmits power to the driven wheel 10 through the belt 9, which in turn causes the driven wheel 10 to drive the first transmission gear 11 to rotate.

[0019] In this embodiment, the first clamping assembly includes a first main clamping block 14 and a first secondary clamping block 18. The first main clamping block 14 and the first secondary clamping block 18 are respectively disposed on the outer side of one end of the pressure valve instrument 3, and both the first main clamping block 14 and the first secondary clamping block 18 are slidably connected to the support table 1. A first main bidirectional toothed belt 12 is fixedly connected to the lower end of the first main clamping block 14, and a first secondary bidirectional toothed belt 16 is fixedly connected to the lower end of the first secondary clamping block 18. Both the first main bidirectional toothed belt 12 and the first secondary bidirectional toothed belt 16 are slidably connected to the upper end of the mounting plate 6, and one side of the first main bidirectional toothed belt 12 meshes with the first transmission gear. On the outside of 11, the second clamping assembly includes a second main clamping block 15 and a second secondary clamping block 19. The second main clamping block 15 and the second secondary clamping block 19 are located on the outside of the other end of the pressure valve instrument 3, and the second main clamping block 15 and the second secondary clamping block 19 are slidably connected to the support table 1. The lower end of the second main clamping block 15 is fixedly connected to a second main bidirectional toothed belt 13, and the lower end of the second secondary clamping block 19 is fixedly connected to a second secondary bidirectional toothed belt 17. The second main bidirectional toothed belt 13 and the second secondary bidirectional toothed belt 17 are both slidably connected to the upper end of the mounting plate 6, and the second main bidirectional toothed belt 13 meshes with the outside of the first transmission gear 11.

[0020] Specifically, the rotation of the first transmission gear 11 will drive the first main bidirectional toothed belt 12 and the second main bidirectional toothed belt 13, which mesh with it, to slide on the upper end of the mounting plate 6. The first main bidirectional toothed belt 12 and the second main bidirectional toothed belt 13 will respectively drive the first main clamping block 14 and the second main clamping block 15 to slide on the support table 1.

[0021] In this embodiment, the lower ends of the first main bidirectional toothed belt 12, the second main bidirectional toothed belt 13, the first secondary bidirectional toothed belt 16, and the second secondary bidirectional toothed belt 17 are all fixedly connected to sliders 20. The upper end of the mounting plate 6 is provided with a groove 21 corresponding to the slider 20, and the slider 20 is slidably connected to the inner side of the groove 21.

[0022] Specifically, the sliding cooperation between the slider 20 and the groove 21 ensures the stability of the first main bidirectional toothed belt 12, the second main bidirectional toothed belt 13, the first secondary bidirectional toothed belt 16 and the second secondary bidirectional toothed belt 17 when sliding on the upper end of the mounting plate 6.

[0023] In this embodiment, a second transmission gear 22 is meshed between the first main bidirectional toothed belt 12 and the first secondary bidirectional toothed belt 16 and between the second main bidirectional toothed belt 13 and the second secondary bidirectional toothed belt 17, respectively. Both second transmission gears 22 are rotatably connected to the upper end of the mounting plate 6.

[0024] Specifically, the first main bidirectional toothed belt 12 and the first secondary bidirectional toothed belt 16, and the second main bidirectional toothed belt 13 and the second secondary bidirectional toothed belt 17 are respectively driven by the second transmission gear 22, so that the first secondary clamping block 18 and the second secondary clamping block 19 slide synchronously in opposite directions, thereby clamping and fixing the two ends of the pressure valve instrument 3. Finally, the pressure valve instrument 3 is firmly clamped on the support table 1, thus preparing for subsequent testing work.

[0025] It should be noted that this utility model is a valve group instrument testing device. The user first inserts the pressure valve instrument 3 into the snap-fit ​​groove 5 at the upper end of the support table 1 through the snap-fit ​​block 4 on its outer side to complete the initial positioning and installation. Then, the drive motor 7 is started. The output end of the drive motor 7 will drive the driving wheel 8 to rotate. The driving wheel 8 transmits power to the driven wheel 10 through the belt 9, which in turn causes the driven wheel 10 to drive the first transmission gear 11 to rotate. The rotation of the first transmission gear 11 will drive the first main bidirectional toothed belt 12 and the second main bidirectional toothed belt 13, which mesh with it, to slide on the upper end of the mounting plate 6. The first main bidirectional toothed belt 12 and the second main bidirectional toothed belt 13 respectively drive the first main clamping block 14 and the second main clamping block 15 to slide on the support table 1. At the same time, the first main bidirectional toothed belt 12 and the first secondary bidirectional toothed belt 16, and the second main bidirectional toothed belt 13 and the second secondary bidirectional toothed belt 17 are respectively driven by the second transmission gear 22, so that the first secondary clamping block 18 and the second secondary clamping block 19 slide synchronously in opposite directions, thereby clamping and fixing the two ends of the pressure valve instrument 3. Finally, the pressure valve instrument 3 is firmly clamped on the support table 1, thus preparing for subsequent testing work, which is quite practical.
