Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve body testing technology, and specifically to a valve life testing system. Background Technology
[0002] Valve life testing is conducted to verify their reliability and durability in practical applications. Valve life testing typically includes a variety of testing methods that simulate the valve's long-term performance under various operating conditions. These tests help predict the valve's lifespan and assess its quality and performance.
[0003] Existing valve life testing systems typically only test the valve body during long-term continuous operation to determine its lifespan. However, their testing methods and types are limited, leading to significant uncertainty in the effectiveness of the tests. For example, pipeline leaks can cause test pressures to be too low or too high, affecting the final valve life test results. Furthermore, because existing testing methods use multiple valve bodies to test the valve under test simultaneously, they occupy a large area and result in cluttered components during installation, hindering efficient testing and reducing overall efficiency.
[0004] Therefore, a new technological solution is needed. Utility Model Content

[0037] This invention addresses the shortcomings of existing testing systems that only test the valve body during long-term continuous operation, which cannot guarantee the stability of the testing environment and leads to a high degree of uncertainty in the effectiveness of the test. By using multiple valve bodies to form a simulated usage scenario for the valve under test 60, and using a parameter detection meter 50 to detect parameters in the pipeline, such as pressure, the test results of the valve under test 60 are closer to the actual valve.
[0038] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.
[0039] like Figures 1-2As shown, this utility model discloses a valve life testing system, comprising a modular connection structure 10, an air inlet structure 20, a manual valve 30, a first normally closed valve 40, a parameter detector 50, a valve under test 60, and a second normally closed valve 70. The air inlet structure 20 is disposed outside the modular connection structure 10; the manual valve 30 is disposed on the modular connection structure 10 and connected to the air inlet structure 20 via a pipe; the first normally closed valve 40 is disposed on the modular connection structure 10 and connected to the manual valve 30 via a pipe, and is located downstream of the manual valve 30; the parameter detector 50 is disposed on the modular connection structure 10 and connected to the first normally closed valve 40 via a pipe, and is located downstream of the first normally closed valve 40; the valve under test 60 is inserted into the modular connection structure 10 and connected to the parameter detector 50 via a pipe, and is located downstream of the parameter detector 50; the second normally closed valve 70 is disposed on the modular connection structure 10 and connected to the valve under test 60 via a pipe, and is located downstream of the valve under test 60.
[0040] The intake structure 20 is used to deliver gas or fluid at a predetermined pressure into the modular connection structure 10 so as to test the valve 60 under test.
[0041] The air intake structure 20 can deliver gas or fluid at different pressures to test the object under different pressures.
[0042] The manual valve 30 allows gas or fluid to pass through when it is open, or blocks the passage of gas or fluid when it is closed.
[0043] Furthermore, both the first normally closed valve 40 and the second normally closed valve 70 are normally closed pneumatic diaphragm valves.
[0044] Furthermore, the parameter sensor 50 is one or more of a pressure sensor, a temperature sensor, and a flow sensor.
[0045] Preferably, the parameter detector 50 is a pressure detector to detect the pressure inside the pipeline, so as to facilitate pressure detection of the valve 60 under different pressures.
[0046] Furthermore, the manual valve 30, the first normally closed valve 40, the parameter detector 50, the valve under test 60, and the second normally closed valve 70 are all detachably connected to the modular connection structure 10, thereby facilitating the replacement of different valve bodies to test the valve under test 60, or the replacement of different models or different types of valve under test 60 for testing.
[0047] Among them, detachable connections can be bolted connections, etc.
[0048] In some embodiments, the modular connection structure 10 includes a base, on which a pipe and a plurality of intermediate holes are provided along a preset path, with the intermediate holes spaced apart along the pipe; wherein, the manual valve 30, the first normally closed valve 40, the parameter detector 50, the valve under test 60, and the second normally closed valve 70 are correspondingly inserted into the plurality of intermediate holes and located on the pipe.
[0049] The input and output ends of the manual valve 30, the first normally closed valve 40, the valve under test 60, and the second normally closed valve 70 are all on the pipeline.
[0050] Furthermore, the substrate includes multiple detachably connected sub-sub-substrate elements, each of which has a corresponding intermediate hole.
[0051] Furthermore, the valve life testing system also includes a controller 80, which is electrically connected to the first normally closed valve 40, the parameter detector 50, and the second normally closed valve 70. The controller 80 is used to acquire the parameter data fed back by the parameter detector 50 and control the opening or closing of the first normally closed valve 40 according to the parameter data.
[0052] Furthermore, the controller 80 includes a timing element disposed within the controller 80, which is used to control the opening time of the first normally closed valve 40 and the second normally closed valve 70.
[0053] The air intake mechanism of this invention is connected to a manual diaphragm valve (manual valve 30) via a modular connection mechanism. The manual diaphragm valve is connected to a first normally closed pneumatic diaphragm valve (first normally closed valve 40) via the modular connection mechanism. The first normally closed pneumatic diaphragm valve is connected to a pressure gauge (parameter gauge 50) via the modular connection mechanism. The pressure gauge is connected to the valve under test (60) via the modular connection mechanism. Finally, the valve under test (60) is connected to a second normally closed pneumatic diaphragm valve (second normally closed valve 70) via the modular connection mechanism. This allows the entire testing system to simulate the actual usage scenario of the valve under test (60) and to monitor the pressure in the pipeline within the testing system in real time via the pressure gauge, thereby improving the accuracy of the test results for the valve under test (60).
[0054] The working process of this utility model is as follows:
[0055] Manually open manual valve 30. After the air intake mechanism introduces gas at the specified pressure, controller 80 controls the first normally closed valve 40 to open, allowing gas to flow to parameter detector 50 and the tested valve 60. Parameter detector 50 provides feedback on whether the pressure of the currently introduced gas has reached the set pressure. Once the pressure is reached, it sends a feedback signal to controller 80. At this point, wait for half a cycle to complete. After the time is up, controller 80 controls the first normally closed valve 40 to close and opens the second normally closed valve 70, waiting for the next half cycle to complete. After the time is up, controller 80 controls the first normally closed valve 40 to reopen, starting the next test cycle.
[0056] The valve life testing system of this utility model has the following advantages:
[0057] (1) Precise measurement: The test system of this utility model incorporates a parameter detector, such as a pressure detector, which ensures that each cycle of the test meets the pressure test requirements during the test process with pressure requirements, making the test results more accurate and closer to the true performance of the valve 60 under test.
[0058] (2) Modular design: This utility model adopts a modular connection mechanism, which makes the system assembly simple, convenient, easy to operate, and the reliability is improved accordingly.
[0059] (3) Compact overall: The present invention adopts a modular connection mechanism, and the final assembled test system is small in size and saves space.
[0060] (4) Enhanced reusability: The test system of this utility model can be disassembled and reinstalled multiple times due to the use of a modular connection mechanism.
[0061] (5) Enhanced independent and combined performance: The test system of this utility model can be used independently or multiple such test systems can be used simultaneously without affecting each other and each is independent.

In particular, for the product embodiments described later, since they correspond to the methods, the descriptions are relatively simple, and the relevant parts can be referred to the descriptions in the system embodiments.
[0063] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
