Description

Technical Field

[0001] This utility model relates to the field of pressure regulation testing technology, specifically a pressure regulating testing device for a pressure reducing valve. Background Technology

[0002] Pressure regulating tests on pressure reducing valves are conducted to ensure their performance, safety, and reliability. The core function of a pressure reducing valve is to stably regulate the inlet high pressure to the required outlet pressure. The test verifies the accuracy of its set pressure and detects its dynamic stability under different operating conditions (such as flow rate changes and pressure fluctuations), preventing damage to downstream equipment caused by overpressure or pressure fluctuations. Furthermore, the test also evaluates the valve's sealing performance, durability, and performance degradation after long-term use, ensuring compliance with industry standards (such as API and ASME) and safety regulations.

[0003] The existing patent publication number CN215831668U discloses a pressure regulating device for a pressure reducing valve, which includes a control cylinder and a cylinder pusher block. When it is necessary to change the output pressure of the pressure reducing valve, the control cylinder pushes the cylinder pusher block to move towards the side of the pressure reducing valve, so that the plunger is sealed to the input end of the pressure reducing valve, opening the air inlet and the ball valve. By checking the pressure gauge reading, the output pressure of the pressure reducing valve is adjusted to the required value.

[0004] When performing a pressure regulating test, the pressure reducing valve needs to be in the closed state. After opening the shut-off valve of the pressure reducing valve, a small flow is used to raise the pressure at the inlet end of the pressure reducing valve to the maximum allowable working pressure. Then, the handwheel of the pressure reducing valve is slowly adjusted so that the outlet pressure changes continuously between the maximum and minimum of the specified outlet pressure range. The above device requires manual adjustment of the handwheel by personnel. Manual operation is labor-intensive, time-consuming, and may also lead to insufficient adjustment accuracy due to human factors, which is quite troublesome. In order to address the above problems, a pressure reducing valve pressure regulating test device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-regulating test device for a pressure-reducing valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure-regulating test device for a pressure-reducing valve includes a workbench, a support block, and a rotating disk disposed on one side of the workbench. A pressure-reducing valve is disposed on the top of the workbench, and an operating wheel is disposed on one side of the pressure-reducing valve. Two sets of positioning blocks are fixedly connected to one side of the rotating disk. A groove for engaging the positioning blocks is provided on one side of the operating wheel. A positioning component for limiting the rotation of the rotating disk is disposed on one side of the workbench.

[0008] The positioning component includes a slide groove and a limiting block. The slide groove is opened on one side of the support block. Several sets of limiting blocks are fixedly connected to the surface of the rotating disk. The rotating disk and the limiting blocks are rotatably connected in the slide groove. Several sets of extrusion grooves are opened in the slide groove. A locking block is slidably connected in the extrusion groove. One end of the locking block is connected to a spring. The end of the spring away from the locking block is connected to the bottom of the inner wall of the extrusion groove. A driving component for driving the rotating disk to rotate is provided on the worktable.

[0009] A base plate is fixedly connected to one side of the workbench, and a fixing component for positioning the pressure reducing valve is provided on the workbench.

[0010] In one alternative embodiment: the driving component includes a movable plate and a support plate, the movable plate being slidably connected to the top of the base plate, the support plate being fixedly connected to one side of the movable plate, the top of the support plate being fixedly connected to the bottom of the support block, a driven wheel being fixedly connected to the side of the rotating disk away from the positioning block, the driven wheel being connected to the driving wheel via a synchronous belt drive, the driving wheel being rotatably connected to one side of the support plate, and a first motor for driving the driving wheel to rotate being mounted on the movable plate.

[0011] In one alternative: the fixing assembly includes a lower cover plate and an upper cover plate, several sets of the lower cover plates are fixedly connected to the top of the workbench, the upper cover plate is disposed on top of the lower cover plate, the inner wall of the upper cover plate overlaps with the outer wall of the pressure reducing valve, and the upper cover plate is connected to the lower cover plate by bolts.

[0012] In one alternative: a guide block is fixedly connected to the bottom of the movable plate, a guide groove is provided on the top of the base plate for sliding with the guide block, a screw is rotatably connected in the guide groove, a threaded hole is provided on the guide block for threaded connection with the screw, and a second motor for driving the screw to rotate is installed in the worktable.

[0013] In one alternative: both the guide groove and the guide block have T-shaped cross-sections.

[0014] In one alternative: the limiting blocks are evenly arranged circumferentially along the central axis of the rotating disk.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a positioning component, a rotating disk, a positioning block, an operating wheel, and a groove. A drive unit rotates the rotating disk, and the positioning component limits its rotation. The rotating disk drives the positioning block to rotate, which in turn drives the operating wheel. As the rotating disk rotates, the limiting block rotates within the groove, pressing against a locking block. This locking block slides within the pressing groove and compresses a spring. When the limiting block rotates between two sets of locking blocks, the spring force ejects the locking block outwards, thus positioning the limiting block. This achieves precise positioning of the rotating disk, reducing the need for manual, slow adjustments to the operating wheel, and the locking block improves the accuracy of rotation adjustment.

[0017] This utility model uses a fixing component to place the pressure reducing valve on two sets of lower cover plates, cover the pressure reducing valve with two sets of upper cover plates, and fix the upper and lower cover plates with bolts, thereby fixing the pressure reducing valve and preventing it from shaking.

[0018] This invention features a guide block, a screw, and a guide groove. When the second motor is started, it drives the screw to rotate, which in turn causes the guide block to slide within the guide groove. This, in turn, causes the moving plate to slide on the top of the worktable, allowing the positioning block to engage with the groove on one side of the operating wheel, facilitating the adjustment of the operating wheel.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] 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.

[0027] Please see Figures 1-5 In this embodiment, a pressure reducing valve pressure regulating test device includes a workbench 11, a support block 19, and a rotating disk 13 disposed on one side of the workbench 11. A pressure reducing valve 24 is disposed on the top of the workbench 11, and an operating wheel 23 is disposed on one side of the pressure reducing valve 24. Two sets of positioning blocks 12 are fixedly connected to one side of the rotating disk 13. A groove for engaging the positioning blocks 12 is provided on one side of the operating wheel 23. A positioning component for limiting the rotation of the rotating disk 13 is disposed on one side of the workbench 11.

[0028] The positioning assembly includes a slide groove 15 and limiting blocks 14. The slide groove 15 is formed on one side of the support block 19. Several sets of limiting blocks 14 are fixedly connected to the surface of the rotating disk 13. The rotating disk 13 and the limiting blocks 14 are rotatably connected within the slide groove 15. Several sets of extrusion grooves 16 are formed within the slide groove 15. A locking block 18 is slidably connected within the extrusion groove 16. One end of the locking block 18 is connected to a spring 17. The end of the spring 17 away from the locking block 18 is connected to the bottom of the inner wall of the extrusion groove 16. The worktable 11 is provided with a driving component for driving the rotating disk 13 to rotate. The driving component drives the rotating disk. When the rotating disk 13 rotates, it drives the limiting block 14 to rotate within the slide groove 15. When the limiting block 14 rotates within the slide groove 15, it presses against the locking block 18. The locking block 18 slides within the pressing groove 16 under pressure and presses against the spring 17. When the limiting block 14 rotates between the two sets of locking blocks 18, the elastic force of the spring 17 pushes the locking block 18 outward. After the locking block 18 is pushed out, it abuts against the side of the limiting block 14, thus achieving precise positioning of the rotating disk 13. This reduces the need for manual adjustment of the operating wheel 23, and the locking block 18 can improve the accuracy of rotation adjustment and enhance the test results.

[0029] A base plate is fixedly connected to one side of the workbench 11, and a fixing component for positioning the pressure reducing valve 24 is provided on the workbench 11.

[0030] The driving component includes a movable plate 26 and a support plate 20. The movable plate 26 is slidably connected to the top of the base plate, and the support plate 20 is fixedly connected to one side of the movable plate 26. The top of the support plate 20 is fixedly connected to the bottom of the support block 19. A driven wheel 22 is fixedly connected to the side of the rotating disk 13 away from the positioning block 12. The driven wheel 22 is connected to the driving wheel 21 via a synchronous belt. The driving wheel 21 is rotatably connected to one side of the support plate 20. A first motor 25 for driving the driving wheel 21 to rotate is installed on the movable plate 26. When the first motor 25 is started, it drives the driving wheel 21 to rotate. The driving wheel 21 drives the driven wheel 22 to rotate via the synchronous belt, thereby driving the rotating disk 13 to rotate. The rotating disk 13 drives the positioning block 12 to rotate. The positioning block 12 is inserted into the groove and drives the operating wheel 23 to rotate, which allows the operating wheel 23 to be slowly adjusted.

[0031] The fixing assembly includes a lower cover plate 31 and an upper cover plate 30. Several sets of the lower cover plates 31 are fixedly connected to the top of the workbench 11. The upper cover plate 30 is disposed on top of the lower cover plates 31. The inner wall of the upper cover plate 30 overlaps with the outer wall of the pressure reducing valve 24. The upper cover plate 30 is connected to the lower cover plates 31 by bolts. The pressure reducing valve 24 is placed on two sets of lower cover plates 31, and two sets of upper cover plates 30 are placed on the pressure reducing valve 24. The upper cover plate 30 and the lower cover plate 31 are fixed with bolts, thereby fixing the pressure reducing valve 24 and preventing it from shaking.

[0032] The bottom of the movable plate 26 is fixedly connected to a guide block 29, and the top of the base plate is provided with a guide groove 28 for sliding with the guide block 29. A screw 27 is rotatably connected in the guide groove 28. The guide block 29 is provided with a threaded hole for threaded connection with the screw 27. A second motor is installed in the worktable 11 to drive the screw 27 to rotate. When the second motor is started, it drives the screw 27 to rotate, thereby causing the guide block 29 to slide in the guide groove 28, and causing the movable plate 26 to slide on the top of the worktable 11, so that the positioning block 12 can be inserted into the groove on one side of the operating wheel 23.

[0033] Both the guide groove 28 and the guide block 29 have T-shaped cross sections. By setting the T-shaped guide groove 28 and guide block 29, the sliding plate 26 can slide more stably.

[0034] The limiting blocks 14 are evenly arranged around the central axis of the rotating disk 13, which can limit the rotation of the rotating disk 13.

[0035] The working principle of this utility model is as follows: In use, firstly, the pressure reducing valve 24 is placed on the two sets of lower cover plates 31, and then the two sets of upper cover plates 30 are placed on top of the pressure reducing valve 24. Bolts are used to fix the upper cover plates 30 and lower cover plates 31, thus fixing the pressure reducing valve 24 and preventing it from shaking. The second motor starts, driving the screw 27 to rotate, thereby causing the guide block 29 to slide within the guide groove 28, and causing the moving plate 26 to slide on the top of the worktable 11, so that the positioning block 12 is engaged in the groove on one side of the operating wheel 23. During adjustment, the first motor 25 starts, driving the drive wheel 21 to rotate. The drive wheel 21 drives the driven wheel 22 to rotate via a synchronous belt, thereby causing the rotating disk 13 to rotate. 3. The positioning block 12 is driven to rotate. The positioning block 12 is inserted into the groove and drives the operating wheel 23 to rotate. When the rotating disk 13 rotates, it drives the limiting block 14 to rotate in the slide groove 15. When the limiting block 14 rotates in the slide groove 15, it squeezes the locking block 18. The locking block 18 is squeezed and slides in the squeezing groove 16 and squeezes the spring 17. When the limiting block 14 rotates between the two sets of locking blocks 18, the elastic force of the spring 17 pops the locking block 18 outward. After the locking block 18 pops out, it abuts against the side of the limiting block 14, realizing the precise positioning of the rotating disk 13. This reduces the need for manual adjustment of the operating wheel 23. In addition, the locking block 18 can improve the accuracy of the rotation adjustment and improve the test results.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
