Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm detection, in particular to a diaphragm bubble point detection device. Background Art

[0002] The diaphragm used in the electrolysis of water to produce hydrogen is a core component. Therefore, accurate and stable testing of diaphragm parameters such as bubble point is crucial.

During the test, the gas pressure at the lower end is continuously increased, and the pore size and bubble point of the object being tested are determined by measuring the gas flux at the upper end. However, conventional visual sensors are often used to observe the presence of bubbles in the electrolyte. While these sensors can accurately detect bubbles, they require assembly into an integrated device, making them unportable and costly.

[0004] Therefore, a diaphragm bubble point detection device is needed to solve the above problems. Utility Model Content

[0040] When testing the diaphragm, in order to accurately test the diaphragm, it is portable and reduces the cost investment, such as Figures 1-6 As shown, the utility model provides a membrane bubble point detection device. The membrane bubble point detection device includes a first component 1, a dense screen 4, a second component 2, an inflation component 3 and a fixing component 5.

[0041] The first component 1 has a visible portion made of transparent material, a first opening 12, and a hollow cavity for accommodating a test reagent. A dense mesh screen 4 is disposed at the end of the first opening 12 of the first component 1, with at least a portion of the mesh of the dense mesh screen 4 communicating with the hollow cavity. The second component 2 has a second opening 22 and a vent groove. The dense mesh screen 4 is disposed between the first opening 12 and the second opening 22, with the vent groove communicating with the hollow cavity through at least a portion of the mesh of the dense mesh screen 4. An inflatable assembly 3 is connected to the vent groove and is used to fill the vent groove with gas. The air pressure of the inflatable assembly 3 is adjustable. A fixing assembly 5 securely connects the second component 2 to the first component 1, so that the second component 2 and the first component 1 abut each other and a diaphragm 8 is clamped between the second component 2 and the dense mesh screen 4. During testing, the diaphragm 8 is sandwiched between the second component 2 and the dense mesh screen 4, and high-pressure gas is introduced into the vent groove of the second component 2 through the inflatable assembly 3. Because the first component 1 has a visible portion made of transparent material, it is possible to observe whether the test reagent generates bubbles. The pressure is then recorded after the pressure is continuously increased until bubbles form in the test reagent. This method allows accurate testing of the diaphragm 8 while reducing costs. Furthermore, the device is simple in structure and easy to carry. In some embodiments, the test reagent can be selected from water or an electrolyte for use as a pore size and bubble point test reagent.

[0042] In some embodiments, the transparent material can be selected from any one of glass and transparent plastic.

[0043] In some embodiments, the detection reagent can be injected into the hollow cavity through the first opening 12 of the first component 1, and then the various components of the detection device are assembled to perform the diaphragm bubble point test. In some embodiments, a liquid injection port connected to the hollow cavity can also be opened outside the first opening 12 of the first component 1, thereby clamping the diaphragm to be tested between the second component 2 and the dense screen 4, and then the detection reagent can be injected from the liquid injection port to perform the diaphragm bubble point test. During the test process, the liquid injection port can be in a completely closed, partially closed or completely open state. The opening of the liquid injection port can make liquid injection more convenient, detection more convenient, and more conducive to improving the detection accuracy.

[0044] In some embodiments, the mesh size of the dense screen 4 is 40-100 meshes, thereby further improving the detection accuracy and effectively preventing the diaphragm 8 from deforming during the test or the dense screen from being too dense, which may cause excessive deviation in the test data.

[0045] In some embodiments, the bubble point detection device of the diaphragm 8 also includes a first sealing gasket assembly 6 and a second sealing gasket assembly 7. The first sealing gasket assembly 6 is arranged at the first opening 12 end of the first component 1, and the first sealing gasket assembly 6 is provided with a accommodating hole 611, and the dense screen 4 is placed in the accommodating hole 611 and connects the first opening 12 and the second opening 22; the second sealing gasket assembly 7 is arranged at the second opening 22 end of the second component 2 and connects with the accommodating hole 611 and the second opening 22, and the second sealing gasket assembly 7 is detachably sealed to the first sealing gasket assembly 6, so that the diaphragm 8 can be clamped between the first sealing gasket assembly 6 and the second sealing gasket assembly 7.

[0046] The second sealing gasket assembly 7 is disposed at the second opening 22 end of the second component 2 and communicates with the accommodating hole 611 and the second opening 22 , that is, the first opening 12 communicates with the second opening 22 through the dense screen 4 , the accommodating hole 611 and the second sealing gasket assembly 7 .

[0047] In some embodiments, the first sealing gasket assembly 6 has a protruding structure relative to the dense mesh screen 4, creating a height difference between the first sealing gasket assembly 6 and the dense mesh screen 4. This protruding structure is provided on the end surface of the first sealing gasket assembly 6 facing the second sealing gasket assembly 7, further ensuring the sealing of the dense mesh screen 4 under test conditions and improving test accuracy. An end surface refers to the plane at one end of each component where it contacts and assembles with other components. For example, the protruding structure provided on the end surface of the first sealing gasket assembly 6 refers to the plane where the first sealing gasket assembly 6 and the second sealing gasket assembly 7 contact and mate with each other.

[0048] In some embodiments, the height difference between the first sealing gasket assembly 6 and the dense screen 4 is greater than 0 mm and not greater than 0.05 mm (i.e., the height of the protruding structure), ensuring that the diaphragm 8 will not undergo significant deformation under pressure, further ensuring the accuracy of the detection.

[0049] In some embodiments, the first sealing gasket assembly 6 and the second sealing gasket assembly 7 can be selected from materials with compressive elasticity, such as silicone, nitrile rubber, hydrogenated nitrile rubber, EPDM rubber, polyurethane rubber, etc. Therefore, after the fixing assembly 5 securely connects the first component 1 and the second component 2, the first sealing gasket assembly 6 and the second sealing gasket assembly 7 undergo elastic deformation under compression, thereby sealing the gap between the first component 1 and the second component 2 and ensuring sealing performance.

[0050] After the second component 2 is connected to the first component 1 using the fixing assembly 5, the first sealing gasket assembly 6 and the second sealing gasket assembly 7 will produce elastic deformation, thereby sealing the gap between the second component 2 and the first component 1, preventing gas and detection reagents from leaking from the gap between the second component 2 and the first component 1.

[0051] In some embodiments, a first mounting portion 11 is provided at the first opening 12 end of the first component 1, and a second mounting portion 21 is provided at the second opening 22 end of the second component 2. The first mounting portion 11 and the second mounting portion 21 are detachably fixedly connected via a fixing assembly 5. This arrangement facilitates rapid assembly of the first component 1 and the second component 2 via the fixing assembly 5.

[0052] In some embodiments, the first mounting portion 11 defines a first mounting groove, and the second mounting portion 21 defines a second mounting groove. The first sealing gasket assembly 6 is disposed within the first mounting groove and at least partially protrudes relative to the end surface of the first mounting portion 11. The second sealing gasket assembly 7 is disposed within the second mounting groove and at least partially protrudes relative to the end surface of the second mounting portion 21. The provision of the first mounting groove facilitates positioning and installation of the first sealing gasket assembly 6, and the provision of the second mounting groove facilitates positioning and installation of the second sealing gasket assembly 7, thereby reducing assembly difficulty. The at least partially protruding provision of the sealing gasket assembly also ensures airtightness during bubble point testing.

[0053] In some embodiments, the first sealing gasket assembly 6 includes a first inner ring 61 and a first outer ring 62, the accommodating hole 611 is opened in the first inner ring 61, the second sealing gasket assembly 7 includes a second inner ring 71 and a second outer ring 72, the first inner ring 61 and the second inner ring 71 are matched and connected to each other, and the first outer ring 62 and the second outer ring 72 are matched and connected to each other, so that the second sealing gasket assembly 7 and the first sealing gasket assembly 6 are detachably sealed.

[0054] The arrangement of the inner and outer rings allows for better positioning of the test size and fixed position of diaphragm 8, ensuring the accuracy and consistency of diaphragm bubble point testing. The size of diaphragm 8 should be larger than the minimum diameter (i.e., inner diameter) of the first and second outer rings 62, 72, but not larger than the maximum diameter (i.e., outer diameter) of the first and second outer rings 62, 72. The first and second inner rings 61, 71 secure and define the bubble point test area of ​​diaphragm 8, while the first and second outer rings 62, 72 further secure and ensure a tight seal in the test environment.

[0055] In some embodiments, the above-mentioned protruding structure is arranged on the end face of the first inner ring 61 facing the second inner ring 71, so that the height difference between the first inner ring 61 and the dense screen 4 is greater than 0 mm and not greater than 0.05 mm (i.e., the height of the protruding structure), which can accurately locate the part to be tested of the diaphragm 8, ensuring that the part to be tested of the diaphragm 8 will not undergo significant deformation under the pressurized state, thereby further improving the test accuracy and consistency.

[0056] In some embodiments, the first mounting portion 11 is provided with a first inner mounting groove 112 and a first outer mounting groove 113. The first inner ring 61 is disposed in the first inner mounting groove 112, and the first outer ring 62 is disposed in the first outer mounting groove 113. Both the first inner ring 61 and the first outer ring 62 protrude relative to the end surface of the first mounting portion 11 of the first component 1. The second mounting portion 21 is provided with a second inner mounting groove 212 and a second outer mounting groove 213. The second inner ring 71 is disposed in the second inner mounting groove 212, and the second outer ring 72 is disposed in the second outer mounting groove 213. Both the second inner ring 71 and the second outer ring 72 protrude relative to the end surface of the second mounting portion 21 of the second component 2. During assembly, the first outer ring 62, the first inner ring 61, the second outer ring 72, and the second inner ring 71 can be quickly positioned to ensure assembly efficiency. Moreover, the protruding arrangement of the inner ring and the outer ring can better ensure that under the extrusion environment when the fixing assembly 5 is fixedly connected, the protruding structures of the inner ring and the outer ring contact each other and undergo elastic deformation, thereby sealing the gap between the first component 1 and the second component 2 and ensuring the sealing performance.

[0057] In some embodiments, a first protrusion 621 is provided on the side of the first outer ring 62 facing the second outer ring 72, and a second groove 721 is provided on the side of the second outer ring 72 facing the first outer ring 62. The first protrusion 621 and the second groove 721 are mutually aligned and connected. A first groove 622 is provided on the side of the first outer ring 62 facing the second outer ring 72, and a second protrusion 722 is provided on the side of the second outer ring 72 facing the first outer ring 62. The second protrusion 722 and the first groove 622 are mutually aligned and connected. This arrangement further enhances the sealing effect by utilizing the fit between the first protrusion 621 and the second groove 721, and the fit between the second protrusion 722 and the first groove 622. In this embodiment, both the fit between the first protrusion 621 and the second groove 721, and the fit between the second protrusion 722 and the first groove 622, are interference fits, further ensuring a good sealing effect.

[0058] In some embodiments, the first protrusion 621 can be in the form of a discontinuous protrusion, a strip-shaped protrusion, or a continuous protrusion ring, or a combination of the two or more. The second groove 721 is provided with a groove structure of a corresponding matching shape at a corresponding position.

[0059] In some embodiments, the second protrusion 722 can be in the form of a discontinuous dot, a strip-shaped protrusion, or a continuous protrusion ring, or a combination thereof; the first groove 622 is provided with a corresponding matching groove structure at a corresponding position. In some embodiments, a first connecting portion 111 is provided on the outer circumference of the first mounting portion 11, and a second connecting portion 211 is provided on the outer circumference of the second mounting portion 21. The first connecting portion 111 and the second connecting portion 211 are detachably connected by a fixing assembly 5. The provision of the first connecting portion 111 and the second connecting portion 211 facilitates the use of the fixing assembly 5 to secure the first mounting portion 11 and the second mounting portion 21.

[0060] In some embodiments, the fixing assembly 5 includes an annular groove 54. The inner wall of the annular groove 54 is provided with a first sealing ring for contacting the first connecting portion and a second sealing ring for contacting the second connecting portion, thereby providing a sealed connection between the first and second connecting portions. The provision of the first and second sealing rings further enhances the sealing effect after the fixing assembly 5 is installed, and eliminates the impact of unevenness of the diaphragm 8 on the sealing effect.

[0061] The fixing assembly 5 comprises a first half-ring 51 and a second half-ring 52. One end of the first half-ring 51 is hinged to one end of the second half-ring 52, and the other end of the first half-ring 51 is connected to the other end of the second half-ring 52 via a stud 53. Specifically, a first lug is provided at the other end of the first half-ring 51, and a second lug is provided at the other end of the second half-ring 52. The first and second lugs are connected via studs 53. The diameter of the fixing assembly 5 can be adjusted by turning the studs 53, facilitating installation and removal of the fixing assembly 5.

[0062] In some embodiments, the inflatable component 3 includes a connected compressed gas tank and a pressure-regulating valve 31. The pressure-regulating valve 31 is connected to the vent groove to regulate the air pressure of the inflatable component 3. A pressure gauge is provided in the air path between the pressure-regulating valve 31 and the second component 2. During testing, the test reagent is poured into the hollow cavity of the first component 1. The pressure-regulating valve 31 is slowly adjusted while visually observing the first component 1. When bubbles are observed in the first component 1, the pressure adjustment of the pressure-regulating valve 31 is stopped, and the pressure displayed on the pressure gauge is manually recorded. The bubble point value of the diaphragm 8 can then be calculated using the Washburn equation.
