TECHNICAL FIELD
[0001] The utility model relates to the field of pressure vessel valve, concretely to a pressure vessel valve mechanism. BACKGROUND
[0002] In the prior art, the detection of pressure vessel valves has the disadvantage of poor equipment versatility. For example, for the two common types of pressure vessel valves, ball valves and gate valves, some existing detection equipment may not be well adapted. The ball body rotating structure of the ball valve and the gate plate lifting structure of the gate valve require different clamps and connection methods to ensure sealing and accurate detection during detection. If a detection device designed for ball valves is used to detect gate valves, sealing may not be tight, and accurate pressure data may not be obtained, and vice versa.
[0003] However, it still has some shortcomings, for example: when detecting valves of different pipe diameters, existing equipment often needs to replace interfaces of different sizes or adjust the entire pressure transmission system. For example, a device for detecting small-diameter valves may not be able to accurately simulate the pressure environment of the valve under actual working conditions when detecting large-diameter valves due to uneven pressure transmission, thereby affecting the accuracy of the detection results.

[0023] Working principle
[0024] A test and inspection mechanism body 8 for pressure vessel valves facilitates the adaptation of different valve types and addresses the challenge of testing valves with different pipe diameters. It provides a relatively simple and highly accurate testing mechanism, capable of adapting to different types of valves, such as ball valves, gate valves, and butterfly valves, and specifications, such as different pipe diameters and pressure ratings, to meet the testing needs of pressure pipelines and valves. Its simple operation reduces the difficulty and workload for testing personnel. By comparing experimental results with the performance of valves in actual pipeline systems, the accuracy of the simulation can be intuitively judged. It can be used to test the performance of different valves within the same pressure vessel, simulating… The test mechanism, designed for actual operating pressure environments, provides valve performance data for R&D personnel. The main body 8 of the testing and inspection unit uses stainless steel as the base material. A pulse pressure pump 1 is connected to the test valve via pressure pipeline 3. A connecting flange 4 is used to connect the test product 41. A pressure sensor 6 is installed inside the test piece to record the working pressure. A pressure gauge serves as a reference for comparing the operating status of the pressure sensor 6. The principle is based on the fact that pressure is the same in all directions within a static, continuous, high-pressure liquid. The main body 8 of the testing and inspection unit consists of a set of pipelines with five common pipe diameters: DN50, DN65, DN80, and DN100.DN125, connected using standard diameter flanges, utilizes the pressure wave generated when a pulse is produced in a high-pressure liquid to monitor pressure changes in various valves. In technical implementation, test product 41 is connected via flange 4. This allows for the simultaneous connection of one or more common specifications and models of pipe valves with flange connections, or the closure of other unnecessary pipes. Opening the vent valve allows the pulse pressure pump to inject pressurized solution into the device, purging internal air and ensuring the test environment is filled with pressurized solution to prevent air from affecting the test results. After closing test product 41 and the vent valve, pressure is applied. Once the required test pressure is reached, the pressure pump is shut off to enter the pressure holding phase. This test simulates the static pressure environment of valves in actual use, testing their sealing performance and stability. A pulse pressure pump 1, through this pipeline, applies pulse pressure to common valves of different specifications and models on the same pipeline, testing their pressure values and fatigue performance. By conducting fatigue pulse tests on valves of different specifications and models through this pipeline, we can observe their fatigue life under different pulse pressure parameters on the same pipeline, i.e., how many pulse pressures they can withstand without failure. For example, when the pulse pressure amplitude increases, the fatigue life of the valve and pipeline may decrease because a larger pressure change amplitude accelerates the fatigue damage process. The operation and testing procedure is as follows: first, ensure all components are correctly installed and connected... Next, check if the pipe connections are tight, if the valves are in the correct initial position, and if the instruments are working properly to ensure the system is leak-free. Start the pulse pressure pump 1. This device will provide power to the entire system, driving the fluid to flow in the pipes and providing a pulse power source. Adjust the fluid flow rate, pressure, and other parameters according to system requirements. These valves may open, close, or adjust their opening degree according to a preset program or manual operation. As the fluid flows, the test valve entering from the pressure pipeline 3 to the connecting flange 4 will perform specific test operations during the fluid flow process. The instruments or sensors marked on the regulating valve and pressure gauge assembly 5 and pressure sensor 6 will monitor the fluid in real time. The system receives pressure and other relevant parameters from the pressure sensor 6 and feeds the data back to the control system. The data acquisition and control system 7 receives data from the pressure sensor 6 and uses this data to control and regulate the system. For example, if the pressure sensor 6 detects that the pressure is too high, the data acquisition and control system 7 may instruct certain valves to adjust to reduce the pressure. When the system needs to be stopped, the pulse pressure pump 1 is first shut down to stop supplying power to the system. Then, according to the operating procedure, each valve is closed sequentially to ensure that the fluid stops flowing and the system is in a safe shutdown state. Finally, the system is inspected and maintained, and relevant data during operation is recorded to prepare for the next operation.
