[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] This invention relates to a device for testing the water pressure resistance of an elastomer film. The device includes a base, with a testing assembly mounted on top of the base. The testing assembly includes a fixed platform bolted to the base, facilitating installation and disassembly, and simplifying maintenance and adjustment. A water-holding cylinder is located on the upper part of the fixed platform, providing space for water during testing.

The filter screen can simulate the pore size of the client's product and be tested according to the client's needs. In addition, the filter screen helps to evenly distribute the pressure and avoid damage to the elastomer membrane caused by sudden water impact, making the test results more accurate.

[0016] The pressure gauge of this invention is provided with a pressure relief valve on one side. After the test is completed, the pressure relief valve can be opened to release the pressure inside the cylinder, which facilitates the subsequent disassembly of the elastomer membrane and enhances safety.

[0017] A first gasket is provided between the lower part of the elastomer film to be tested and the mounting base, and a first boss adapted to the first gasket is provided on the upper part of the mounting base. The function of the first gasket is to enhance the sealing between the elastomer film to be tested and the mounting base, preventing water from seeping out from the gap between them and affecting the test results. At the same time, the first boss can better position the first gasket, making the first gasket more stable during installation and further improving the sealing effect.

[0018] The filter screen is 60-100 mesh in size, which better meets the needs of customers.

[0019] A second gasket is provided between the filter screen and the cover plate, and a second protrusion adapted to the second gasket is provided on the lower part of the cover plate. The function of the second gasket is to further fix the filter screen and prevent it from shifting during the test, while the second protrusion can accurately position the second gasket, ensuring that the filter screen is installed firmly and guaranteeing the stability of the test process.

[0020] The cylinder is equipped with scale lines inside, which allows for more intuitive monitoring of the water level inside the cylinder, enabling timely replenishment and ensuring the accuracy of the test results. Attached Figure Description

[0028] like Figure 1-4As shown, an elastomer film 8 water pressure resistance testing device includes a base 1, with a testing component on the upper part of the base 1. The testing component includes a fixed platform 2 bolted to the base 1, which facilitates installation and disassembly, and makes maintenance and adjustment of the device convenient. A water-holding cylinder 3 is located on the upper part of the fixed platform 2, providing space for water to be contained during testing. An air inlet pipe 11 introduces air from the bottom of the cylinder 3, causing the water to rise and apply pressure to the elastomer film 8 during the test. During the test, the test pressure is adjusted according to the reading on the pressure gauge 10 and via a regulating valve 9 to ensure the accuracy of the test results. An annular mounting seat 4 is located on the upper part of the cylinder 3, and a cover plate 5 is bolted to the upper part of the mounting seat 4. The bolted connection ensures a tight connection between the cover plate 5 and the mounting seat 4, guaranteeing a seal during the test. The cover plate 5 has a through hole 6; when water seeps out of the through hole 6, it indicates that the elastomer film 8 has lost pressure. A filter screen 7 and the elastomer film 8 to be tested are arranged sequentially from top to bottom between the cover plate 5 and the mounting seat 4. The filter 7 can simulate the pore size of the client's product and perform testing according to the client's needs. In addition, the setting of the filter 7 helps to evenly distribute the pressure and avoid damage to the elastomer membrane 8 caused by sudden water impact, making the test results more accurate.

[0029] A pressure relief valve 12 is provided on one side of the pressure gauge 10. After the test is completed, the pressure relief valve 12 can be opened to release the pressure inside the cylinder 3, which facilitates the subsequent disassembly of the elastomer membrane 8 and enhances safety.

[0030] A first gasket 13 is provided between the lower part of the elastomer film 8 to be tested and the mounting base 4, and a first boss 15 adapted to the first gasket 13 is provided on the upper part of the mounting base 4. The function of the first gasket 13 is to enhance the sealing between the elastomer film 8 to be tested and the mounting base 4, preventing water from seeping out from the gap between them and affecting the test results. At the same time, the first boss 15 can better position the first gasket 13, making the first gasket 13 more stable during installation and further improving the sealing effect.

[0031] The size of the filter 7 is 60-100 mesh, which better meets the needs of customers.

[0032] A second gasket 14 is provided between the filter screen 7 and the cover plate 5, and a second protrusion 16 adapted to the second gasket 14 is provided at the lower part of the cover plate 5. The function of the second gasket 14 is to further fix the filter screen 7 and prevent the filter screen 7 from shifting during the test, while the second protrusion 16 can accurately position the second gasket 14 to ensure that the filter screen 7 is installed firmly and to ensure the stability of the test process.

[0033] The cylinder 3 is equipped with scale lines 17 inside, which allows for more intuitive monitoring of the water level inside the cylinder 3, enabling timely replenishment and ensuring the accuracy of the test results.

[0034] The working principle of this utility model:

[0035] Device installation

[0036] First, securely install the mounting platform 2 onto the base 1 using bolts, ensuring a tight, secure connection between the mounting platform 2 and the base 1 without any wobble. Next, place the first gasket 13 on the upper part of the mounting base 4, accurately positioning it on the first boss 15 to ensure a good seal. Place the elastomer film 8 to be tested flat on the first gasket 13, taking care to avoid wrinkles or misalignment. Then, place the filter screen 7 on the elastomer film 8, followed by the second gasket 14 on the filter screen 7, accurately positioning it on the second boss 16. Finally, connect the cover plate 5 to the mounting base 4 using bolts, tightening the bolts to ensure a good seal between the cover plate 5 and the mounting base 4.

[0037] Test preparation

[0038] Connect the air inlet pipe 11 to an external air source, and close the passage between the air inlet pipe 11 and the cylinder 3 using the regulating valve 9. Inject an appropriate amount of water into the cylinder 3, ensuring the water level meets the test requirements. Install the pressure gauge 10 on the pipeline, ensuring a tight connection and no air leaks. Simultaneously check that the pressure relief valve 12 is functioning correctly.

[0039] Testing process

[0040] Open the regulating valve 9 and slowly introduce gas into the cylinder 3. Control the gas introduction rate and pressure by observing the reading of the pressure gauge 10. As the pressure gradually increases, observe the state of the elastomer membrane 8 under test. When there is obvious water seepage through the through hole 6, record the reading of the pressure gauge 10 at this time. This reading is the water pressure resistance value of the elastomer membrane 8. After the test is completed, turn off the gas source, open the pressure relief valve 12 to release the pressure inside the cylinder 3, and then disassemble the device to clean the residual water and impurities inside, preparing for the next test.
