TECHNICAL FIELD
[0001] The present application relates to the technical field of valve experiments, in particular to a valve experiment platform facilitating experimental pipeline reuse. BACKGROUND
[0002] The valve experiment platform facilitating experimental pipeline reuse for industrial testing is a highly integrated and automated comprehensive testing system designed specifically for accurately evaluating the performance and reliability of valve products under simulated real-world conditions. The platform typically consists of a high-pressure fluid power module, a high-precision sensor array, a servo closed-loop control unit, and professional data acquisition and processing software. It can perform a series of rigorous tests on valves according to industry standards (such as API, ASME, ISO) or specific specifications. Its core testing capabilities include shell strength testing, high and low pressure sealing testing, including air and liquid tightness, and evaluating leakage levels, flow and resistance coefficients (Cv / Kv values), opening and closing torque / operation force monitoring, and durability (lifetime) cycle testing simulating long-term use. The entire platform precisely adjusts pressure, flow, and valve opening through a central control system, and real-time collects and analyzes key parameters such as pressure, temperature, torque, and displacement, generating test reports that meet certification requirements. It is an indispensable key equipment for valve research and development, factory quality inspection, and safety certification.
[0003] In the prior art, since enterprises are involved in the research and production of various valve components, the structure, inlet and outlet port quantity, and working principle of each valve component are different, and therefore each corresponding valve experiment pipeline is designed separately. Since the experimental process of valve experiments mainly constructs the use conditions during normal use of the valve, the difference between each valve experiment lies only in the combination of the pipeline, and therefore the valve experiment platform facilitating experimental pipeline reuse usually does not specify a fixed pipeline, but provides a platform that can freely assemble the pipeline, and the corresponding pipeline is constructed by connecting elements through high-pressure hoses. Since each valve experiment needs to be assembled, the experimental process is relatively troublesome. Therefore, some pipelines with high reuse rate or importance can be stored in a complete set, and then directly taken out for use during subsequent reuse. However, this raises new problems. First, there are high-cost elements such as reversing valves, pressure gauges, and sensing components in the pipeline, and each stored pipeline requires an additional one, which is costly. Second, the pipeline is mainly composed of pipes, which are prone to entanglement during storage, and are not easy to take out. Fixing the entire pipeline system with a frame can solve the problems of pipe entanglement and taking out, but the single frame occupies a large volume, and the required storage space also increases. SUMMARY
[0004] To address the aforementioned problems, this invention provides a valve testing platform that facilitates the reuse of experimental pipelines. This platform allows for the complete storage of experimental pipelines used in valve testing, reducing the volume of the pipelines during storage and lowering storage costs by sharing high-cost components.
[0005] This invention is achieved through the following technical solution: a valve test platform that facilitates the reuse of experimental pipelines, including an operating platform, an experimental tank on the operating platform, a telescopic platform on one side of the experimental tank along its length, and a plurality of liquid inlets and outlets on the side of the experimental tank away from the telescopic platform and on the telescopic platform, respectively, with flap gates provided on both the liquid inlets and outlets. Several electromagnet plates are provided on one side of the experimental tank in the width direction, and a telescopic drive rod is provided on the other side of the experimental tank in the width direction. One end of the telescopic drive rod is detachably connected to a structural rod, and a clamp is slidably connected to the structural rod. The clamp is used to hold the pipeline or component in the valve experiment. The telescopic drive rod is used to drive the structural rod to move along the length direction of the experimental tank. The electromagnet plates are used to fix the structural rod by magnetic attraction. The experimental tank has a wax injection port on one side, which is connected to a wax injector used to inject molten wax into the experimental tank.
[0006] Furthermore, heating wires are installed on the side walls of the experimental tank.
[0007] Furthermore, it also includes a bag, with a frame fixedly connected to the operating platform, a top plate fixedly connected to the top of the frame, and several ropes fixedly connected to the bottom of the top plate. Several hooks are slidably connected to the ropes. The bag is used to cover the components in the valve experiment, and the hooks are used to hang the bag.
[0008] Furthermore, the top of the bag is equipped with an opening and a hanging rope, and the bag has a pipe connection port.
[0009] Furthermore, the pipe connection ports and sleeves are all fixedly connected with spiral wrapping tape.
[0010] Furthermore, an air pump is fixedly connected to the top plate, and the air pump is connected to several air pipes.
[0011] Furthermore, the side wall of the bag is provided with a cavity, and the bag is provided with an injection port, which is connected to the cavity.
[0012] Furthermore, a cabinet is provided on one side of the operating platform, and the cabinet contains several storage compartments.
[0013] Furthermore, the storage compartment contains several nameplates, with barbs on the back of each nameplate.
[0014] Furthermore, the operating platform is equipped with air vents, which are connected to a refrigeration unit.
[0015] The technical solution of the present invention has at least the following beneficial effects: In use, users can assemble experimental pipelines within the experimental tank using pipes and related components such as directional valves, pressure gauges, and sensors. Inlet and outlet ports are provided on both sides of the experimental tank to supply and circulate the experimental fluid. Several inlet and outlet ports are provided to accommodate valves with varying numbers of interfaces.
[0016] Once the user has assembled and stored the experimental tubing as a whole, wax is injected into the experimental tank through the wax inlet. Due to its fluidity, the wax coats the tubing. After the wax solidifies, it secures the entire tubing, forming a wax block that matches the shape of the experimental tank. The user can then remove the wax block from the experimental tank for tubing storage. The flap valve seals unused inlets or outlets to prevent molten wax from entering.
[0017] However, wax block processing results in the wax block's volume being the same as the experimental tank's size. Some simple experiments don't require much space, leading to low space utilization. Since there are no fixed components within the experimental tank, components can move within it, and the tubing can be bent, as long as the bending doesn't affect the experimental process. Therefore, users can use clamps on the structural rods to fix the tubing or components in the valve experiment and adjust the component's position by controlling the telescopic drive rod, causing the tubing between components to bend. An electromagnet plate can attract and fix the structural rod after its position is adjusted, thus maintaining its position during wax injection. Through multiple guide rods, the experimental tubing is compressed through bending, tightly constrained within a smaller space. The telescopic platform can adjust according to the compression of the experimental tubing, reducing the length of the wax injection area within the experimental tank. Thus, after wax injection, the wax block will have different volumes depending on the complexity of the experimental tubing, improving the space utilization within the wax block.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] The following detailed description illustrates the specific implementation method: Example 1 As attached Figures 1-7As shown, a valve testing platform for easy reuse of experimental pipelines includes an operating platform 1, on which a test tank 2 is provided. A telescopic platform 3 is provided on one side of the test tank 2 along its length. Several inlets 4 and outlets 5 are respectively provided on the side of the test tank 2 away from the telescopic platform 3 and on the telescopic platform 3. The telescopic platform 3 is a nested telescopic structure with a flexible hose inside to maintain liquid discharge capacity after repositioning. Both the inlets 4 and outlets 5 are equipped with flaps 6. Heating wires (not shown in the figure) are provided on the side walls of the test tank 2, and a wax discharge port 13 is provided at the bottom of the test tank 2.
[0024] Several electromagnet plates 7 are installed on one side of the experimental tank 2 in the width direction, and a telescopic drive rod 8 is provided on the other side of the experimental tank 2 in the width direction. The telescopic drive rod 8 is a multi-stage cylinder, and a structural rod 9 is detachably connected to one end of the telescopic drive rod 8. A clamp 10 is slidably connected to the structural rod 9. The clamp 10 is used to clamp the pipeline or component in the valve experiment. The telescopic drive rod 8 is used to drive the structural rod 9 to move along the length direction of the experimental tank 2. The electromagnet plates 7 are used to fix the structural rod 9 by magnetic attraction. In this embodiment, there are two structural rods 9. One structural rod 9 is magnetically attracted and fixed to the electromagnet plate 7, and the other remains connected to the telescopic drive rod 8 (it is movable).
[0025] The experimental tank 2 has a wax injection port 11 on one side, and the wax injection port 11 is connected to a wax injector 12, which is used to inject molten wax into the experimental tank 2.
[0026] It also includes a cover bag 14. A frame 15 is bolted to the operating platform 1. A top plate 16 is bolted to the top of the frame 15. Several ropes 17 are attached to the bottom of the top plate 16. Several hooks 23 are slidably connected to the ropes 17. The cover bag 14 is used to cover the components in the valve experiment. The hooks 23 are used to hang the cover bag 14. The top of the cover bag 14 is provided with a cover opening 1401 and a hanging rope 1402. The cover bag 14 has a pipe connection port 1403. The pipe connection port 1403 and the cover opening 1401 are both glued and fixed with a winding tape 1404. An air pump (not shown in the figure) is bolted to the top plate 16. The air pump is connected to several air pipes 18.
[0027] In use, users can assemble experimental piping within experimental tank 2 using pipelines and related components such as directional valves, pressure gauges, and sensors. The piping is high-pressure flexible tubing to accommodate different layouts. Experimental tank 2 provides inlet ports 4 and outlet ports 5 on both sides to supply and circulate experimental fluids. Since different valves have varying numbers of interfaces, and some components also require fluid connection, several inlet ports 4 and outlet ports 5 are provided to accommodate valves and components with different numbers of interfaces.
[0028] When the user completes the assembly and stores the experimental tubing as a whole, wax is injected into the experimental tank 2 through the wax injection port 11. Due to its fluidity, the wax will encapsulate the tubing. After the wax solidifies, it will fix the entire tubing in place, forming a wax block that matches the shape of the experimental tank 2. The user can then remove the wax block from the experimental tank 2 for tubing storage. The flap gate 6 seals unused inlet ports 4 or outlet ports 5 to prevent molten wax from entering.
[0029] Some components are expensive, and using high-cost components individually in each wax block would increase the overall cost. Therefore, a sleeve 14 is used to wrap around the components or valves. The top of the sleeve 14 is held in place by a hook 23, preventing the wax from covering the components or valves during wax injection. The user can then remove the components or valves from the sleeve 14 after the wax block has formed. Subsequently, only low-cost components, pipes, and structural rods 9 are sealed inside the wax block. Higher-cost components are installed only when needed, allowing different experimental pipelines to share higher-cost components, thus reducing costs.
[0030] The hook 23 can slide on the rope 17, making it easy for the user to adjust the position of the hook 23 so that it is positioned above the pipe or component. The sleeve 14 has a pipe connection port 1403, which allows the pipe to protrude from the sleeve 14 through the pipe connection port 1403. The pipe connection port 1403 is wrapped and tied tightly to the pipe using the wrapping tape 1404 to prevent molten wax from entering the sleeve 14 through the pipe connection port 1403 during wax injection.
[0031] The air tube 18 can be inserted into the bag 14 through the opening 1401. The air pump injects air into the bag 14 through the air tube 18. The wrapping tape 1404 can also tightly bind the opening 1401 of the bag 14 to the air tube 18 to reduce gas leakage. When wax is injected later, the bag 14 will inflate because of the gas injected into it, expanding the wax-free area of the bag 14 and preventing the bag 14 from being crushed by the molten wax.
[0032] The wax block treatment will make the volume of the wax block the same as the size of the experimental tank 2. Some simple experiments do not require much space, which makes the space utilization rate of the wax block low. Since there is no structure to fix the components in the experimental tank 2, the components can move within the experimental tank 2. In addition, the pipeline can be bent, as long as the bending degree does not affect the experimental process. Therefore, the pipeline can be bent to a certain extent to reduce the overall area occupied by the experimental pipeline. Thus, the user can use the clamp 10 on the structural rod 9 to fix the pipeline or components in the valve experiment, and adjust the position of the components by controlling the telescopic drive rod 8 to bend the pipeline between the components. The electromagnet plate 7 can attract and fix the structural rod 9 after the structural rod 9 is adjusted in position, so that the structural rod 9 still maintains its position during the wax injection process. Guided by multiple structural rods 9, the experimental pipeline is compressed through pipe bending and tightly constrained within a small space. The structural rods 9 can finely adjust the bending range of the pipeline to avoid excessive bending or failure to reduce the occupied area. The telescopic platform 3 can be replenished according to the compression of the experimental pipeline, thereby reducing the length of the wax injection area in the experimental tank 2. In this way, after wax injection, the wax block will have different volumes according to the complexity of the experimental pipeline, improving the space utilization rate within the wax block.
[0033] Once the wax block has solidified, it adheres to the side wall of experimental tank 2, making it difficult to remove. Furthermore, the close proximity of the wax block's edge to the side wall hinders the installation and disassembly of piping. A heating wire is installed on the side wall of experimental tank 2. When the heating wire is energized, it melts the wax near the side wall, creating a gap between the wax block and the side wall. This facilitates the removal of the wax block and the installation and disassembly of piping. A wax drain port 13 is located at the bottom of experimental tank 2, allowing the melted wax to be drained after the heating wire heats up.
[0034] Example 2 The difference from the above embodiment is that the side wall of the bag 14 is provided with a cavity 1405, and the bag 14 is provided with an injection port 1406, which is connected to the cavity 1405.
[0035] The side wall of the bag 14 is provided with a cavity 1405, so that after the wax block is formed, the user can inject a fluid with temperature into the bag 14 through the injection port 1406, thereby melting the wax on the outside of the bag 14, making it convenient to remove and open the bag 14.
[0036] Example 3 The difference from the above embodiment is that the operating platform 1 has a cabinet on one side, and the cabinet has several storage compartments 19. Several nameplates 20 are stored in the storage compartments 19, and the back of the nameplates 20 is provided with needles 21.
[0037] The cabinet allows users to conveniently store experimental tubing, components, consumables, and other items. Since wax is whitish and its internal state is difficult to observe, several nameplates 20 are placed in the storage compartment 19. The nameplates 20 can be inserted into the wax block by the needles 21 on their backs and then fixed to the wax block. The nameplates 20 can indicate the valves used in the experimental tubing stored in the wax block, and can also identify the components and valves in the bag 14, so as to facilitate the subsequent installation of higher-cost components into the experimental tubing.
[0038] Example 4 The difference from the above embodiment is that the operating platform 1 is provided with a cold air outlet 22, and the cold air outlet 22 is connected to a cooler.
[0039] The wax block has a low melting temperature, which ensures operational safety and reduces the risk of burns to the user. However, it is also prone to melting due to higher temperatures or component heating. Therefore, a cooling air nozzle 22 is installed on the operating platform 1. The cooling air nozzle 22 continuously blows out cooling air to cool the wax block and prevent it from melting and affecting the experimental process.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
