[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a flange sealing ring testing device includes a base 11, a placement block 19 for placing a flange housing 20 is installed on the upper end of the base 11, an upper pressure block 18 is arranged directly above the placement block 19, a plurality of support rods 12 are fixed on the upper end of the base 11, the upper ends of the plurality of support rods 12 are fixedly connected to the lower end of a top seat 13, and an adjustment structure for adjusting the upper pressure block 18 is provided on the top seat 13;

[0025] The flange housing 20 includes a bottom shell 201 and interfaces 202 symmetrically fixed on both sides of the upper end of the bottom shell 201. A sealing ring 203 is installed at the lower end of the bottom shell 201.

[0026] In this embodiment, during testing, the flange housing 20 with the sealing ring 203 is placed on the placement block 19, and the adjustment structure drives the upper pressure block 18 to move downward until the upper pressure block 18 contacts the flange housing 20, thereby performing the next step of sealing performance testing of the sealing ring 203.

[0027] In an optional embodiment, the upper end of the placement block 19 is provided with a fixing groove 192 that matches the sealing ring 203, and an air inlet 191 is provided on one side of the placement block 19. The fixing groove 192 is connected to an external pipe and communicates with the air supply equipment through the air inlet 191.

[0028] It should be noted that when the gas supply equipment delivers gas to the fixed slot 192, the upper pressure block 18 is moved downward by the adjustment structure until it comes into contact with the flange housing 20. This makes the air inlet 191 of the placement block 19, the fixed slot 192 and the flange housing 20 form a sealed area to prevent gas from escaping.

[0029] In an optional embodiment, a barometer is installed in the mounting slot 192.

[0030] It should be noted that the barometer monitors the air pressure changes in the fixed groove 192 in real time, thereby providing feedback on the sealing performance of the sealing ring 203 during the sealing test.

[0031] In an optional embodiment, the adjustment structure includes a movable plate 15 located below the top seat 13. The corner of the movable plate 15 slides against the outer wall of a plurality of support rods 12 fixed to the upper end of the base 11. An upper pressure block 18 is fixed to the middle of the lower end of the movable plate 15.

[0032] It should be noted that the corner of the movable plate 15 is slidably connected to the outer wall of several support rods 12, which ensures the stability and accuracy of the movement of the movable plate 15.

[0033] In an optional embodiment, the adjustment structure further includes a cylinder 14 mounted on the upper end of the top seat 13, the telescopic end of the cylinder 14 extending to the lower end of the top seat 13 and fixedly connected to a movable plate 15.

[0034] It should be noted that the telescopic end of the cylinder 14 extends downward, causing the movable plate 15 fixed thereon to move downward along the support rod 12. As the movable plate 15 moves downward, the upper pressure block 18 fixed at the lower end of the movable plate 15 also moves downward.

[0035] In an optional embodiment, a lower abutment rod 17 is fixed to the upper end of the base 11, and an upper abutment rod 16 corresponding to the position of the lower abutment rod 17 is fixed to the lower end of the movable plate 15.

[0036] It should be noted that when the upper abutment rod 16 contacts the lower abutment rod 17, it can play a limiting role, preventing the movable plate 15 from continuing to move downward and causing excessive compression to the flange housing 20.

[0037] In an optional embodiment, two fixing holes 181 are symmetrically provided on both sides of the lower end of the upper pressure block 18, and the two fixing holes 181 are respectively matched with two interfaces 202.

[0038] It should be noted that when the upper pressure block 18 continues to move downward, the two interfaces 202 are respectively inserted into the corresponding fixing holes 181, so that air cannot flow through the interfaces 202, forming a sealed area with the air inlet 191 of the placement block 19, the fixing groove 192 and the flange housing 20; and fixing the flange housing 20 to ensure that the flange housing 20 will not move or shake during the test, thus ensuring the accuracy of the test.

[0039] The above embodiment discloses a flange sealing ring testing device, wherein, during testing, the flange housing 20 with sealing ring 203 is placed on the placement block 19, the bottom shell 201 of the flange housing 20 is placed on the placement block 19, and the sealing ring 203 is correspondingly inserted into the fixing groove 192 that matches the sealing ring 203 at the upper end of the placement block 19.

[0040] The cylinder 14 mounted on the upper end of the top seat 13 is activated. The telescopic end of the cylinder 14 extends downward, pushing the movable plate 15 to slide downward along the outer wall of several support rods 12 fixed to the upper end of the base 11. The upper pressure block 18 at the lower center of the movable plate 15 moves downward accordingly until the upper pressure block 18 presses against the flange housing 20, ensuring that the flange housing 20 remains stable during the testing process. At this time, the two fixing holes 181 block the two interfaces 202, thereby forming a sealed area with the air inlet 191 of the placement block 19, the fixing groove 192, and the flange housing 20.

[0041] The gas supply equipment supplies gas to the fixed groove 192, and the gas acts on the sealing ring 203. A pressure gauge is installed in the fixed groove 192, which monitors the pressure changes in the fixed groove 192 in real time. If the sealing ring 203 has a good sealing performance, the gas will not leak, and the pressure value displayed by the pressure gauge will remain stable; if there is a sealing problem with the sealing ring 203, the gas will leak, and the pressure value displayed by the pressure gauge will change. By observing the change in the pressure gauge reading, it can be determined whether the sealing performance of the flange sealing ring 203 is qualified.

[0042] The above description is merely a specific embodiment 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.
