[0025] like Figures 1-3 As shown, an emergency flap valve air tightness strength test device includes a base 2, a cover 1 is fixed on the base 2, and a test piece 3 is arranged in the cover 1 and fixed on the base 2;
[0026] An observation window is provided on the top of the cover 1 , and a first control valve 5 , a second control valve 6 and a pressure gauge 7 are connected on the cover 1 . The first control valve 5 is provided at the bottom of the cover 1 , and the second control valve 6 is provided at the top of the cover 1 .
[0027] Test piece 3 is mounted on base 2, and cover 1 is installed outside of test piece 3, forming a sealed cavity between test piece 3 and cover 1. Pressurized gas or liquid can be introduced into the sealed cavity through second control valve 6 to simulate the airtightness of test piece 3 under different high-pressure environments. An observation window allows for intuitive observation of the test status of test piece 3, and a pressure gauge 7 provides feedback on the pressure within the sealed cavity. First control valve 5 is used to exhaust the pressurized gas or liquid after the test is completed.
[0028] Pressurized gas or liquid can be introduced into the closed cavity through the second control valve 6 to accurately simulate various high-pressure working environments and test the airtightness and strength of the tongue valve under these conditions. The design of the observation window allows the operator to observe the status of the test product in real time without interrupting the test; the pressure gauge 7 provides real-time data on the pressure in the closed cavity, ensuring the safety and reliability of the test. The first control valve 5 is used to empty the pressure medium, which simplifies the cleanup work after the test and improves work efficiency. By conducting strict airtightness and strength tests on the tongue valve, potential problems in product design or manufacturing can be discovered in a timely manner, thereby improving product quality and ensuring its reliability and safety in actual applications. The device can flexibly adjust pressure parameters and is suitable for testing tongue valves of different types and specifications, with a wide range of applicability.
[0029] Preferably, an outer flange 201 is fixedly provided on the outer side of the top of the base 2, and the bottom of the cover 1 is fixedly connected to the outer flange 201 through a flange and bolts;
[0030] An inner flange 202 is fixedly provided on the inner side of the top of the base 2 , and the test piece 3 is fixed to the inner flange 202 by bolts.
[0031] It is fixed by corresponding flanges and bolts, and the overall connection is airtight.
[0032] An external flange 201 is fixed to the top and outside of the base 2, providing a stable mounting base for the cover 1. The bottom of the cover 1 is securely connected to the external flange 201 via a flange and bolts. This connection not only ensures a tight fit between the cover and the base, but also provides sufficient mechanical strength to prevent leakage or loosening even in high-pressure environments.
[0033] An inner flange 202 is fixed on the inner side of the top of the base 2 for mounting the test object 3. Connection method: The test object 3 is fixed to the inner flange 202 by bolts, so that the test object can be firmly mounted on the base and form a completely closed cavity between the test object and the cover.
[0034] The dual protection of outer flange 201 and inner flange 202 ensures the tightness of the entire system. This is especially true for tests that simulate high-pressure environments, where good sealing is crucial for test accuracy. The flange and bolt connection provides uniform pressure distribution, effectively preventing any potential leaks and ensuring stable pressure within the sealed chamber.
[0035] Preferably, the inner flange 202 is hollow, and the valve core of the test product 3 is connected to the outside through the inner hollow of the inner flange 202;
[0036] A monitoring device 10 is provided directly below the inner flange 202 , and the monitoring device 10 is used to monitor the valve core of the test product 3 .
[0037] When the air tightness of the valve core of the test product 3 fails to meet the requirements, the gas or liquid in the cover 1 will leak from the valve core, and the monitoring device 10 can detect the sound of the leaking gas or the leakage of the liquid.
[0038] The inner flange 202 is hollow, allowing the valve core of the test piece 3 to be directly connected to the outside world. This design allows for leaks in the valve core during air tightness testing. If there is a leak in the valve core, gas or liquid can leak from the valve core into the hollow area inside the inner flange and eventually be captured by the monitoring device 10.
[0039] Monitoring equipment 10 is located directly below inner flange 202 and is used to directly monitor the valve core of test product 3. Gas sound monitoring: In the event of a gas leak, the monitoring equipment can determine whether the valve core is airtight by detecting the sound produced by the leak. Liquid leakage monitoring: In the event of a liquid leak, the monitoring equipment can detect the presence of liquid leakage, promptly discovering and recording the leak.
[0040] The monitoring device 10 can quickly respond to any valve core leakage, providing immediate feedback and ensuring the accuracy of test results. Whether it is a tiny gas sound or a slight liquid leak, the monitoring device can effectively capture it, improving the sensitivity of the detection.
[0041] By monitoring the air tightness of the valve core in real time, leaks can be detected at an early stage, preventing more serious failures or accidents in high-pressure environments. Prompt detection of leaks helps take necessary protective measures and reduces potential safety risks.
[0042] The monitoring device 10 can realize automatic continuous monitoring, eliminating the need for frequent manual inspections, saving time and labor costs. The monitoring device usually has a data recording function, which can save the data of each test for subsequent analysis and report generation.
[0043] Through rigorous testing of valve core air tightness, we ensure that each flap valve product meets high quality standards. If a substandard product is found, the cause of the problem can be traced through monitoring data to help improve the production process.
[0044] Preferably, a support 4 is fixed on the periphery of the base 2, and the support 4 is used to support the entire device.
[0045] Preferably, the top of the cover 1 is provided with an opening, a flange is provided at the opening, an end cover 8 is connected to the flange by bolts, and a glass window 9 is fixed between the end cover 8 and the flange. Seals are provided on both sides of the glass window 9 and between the flange and the end cover 8 respectively.
[0046] The top of the cover 1 is opened for mounting an observation glass window 9. A flange is provided at the opening, to which the end cap 8 is secured by bolts. This flange and bolt connection ensures a tight fit between the end cap and the cover, providing excellent mechanical strength and sealing performance.
[0047] Glass window 9 is located at the top opening of cover 1, embedded between the flange and end cap 8. Seals are installed on both sides of the glass window, between the flange and end cap 8, ensuring a complete seal around the window and preventing gas or liquid leakage. The presence of the glass window allows the operator to visually observe the changes in the state of test article 3 during the test, ensuring safe testing.
[0048] Preferably, a seal is provided between the cover 1 and the test piece 3 and the outer flange 201 and the inner flange 202. The seal can ensure the sealing of the sealed cavity and the reliability of the test.
