[0002] Sealing materials are currently widely used in various fields, such as construction, nuclear power, and military industries. Different industries and operating environments have different requirements for the sealing performance of materials. Therefore, performance testing of sealing materials is particularly critical.

[0003] During construction, holes are often reserved in walls or floors for laying pipes or wiring. After the work is completed, these holes need to be sealed with sealing materials. However, there is a lack of effective experimental methods to verify the sealing performance of sealing materials, making it difficult to guarantee the sealing effect of sealing materials. Summary of the Invention

[0004] In order to test the sealing performance of a sealing material, the present application provides a sealing device for testing the sealing performance of a material.

[0005] The present application provides a sealing device for testing the sealing properties of a material, which adopts the following technical solution:

[0006] A sealing device for testing the sealing performance of a material comprises a sealing cover and a prefabricated frame. The prefabricated frame is provided with an annular sealing groove on the surface facing the sealing cover. The sealing cover is connected to an instrument port and a pressure port. The center of the prefabricated frame is provided with a detection groove for filling the sealing material.

[0007] By adopting the above technical solution, the operator fills the test groove with sealing material, inserts a sealing ring into the sealing groove, places the sealing cover on the prefabricated frame, seals the prefabricated frame on all sides, and injects fluid into the prefabricated frame through the pressure port on the sealing cover. As the injection pressure increases, the sealing performance of the sealing material is tested. Because the prefabricated frame is sealed on all sides, and the sealing material is also used to seal the prefabricated frame and the sealing cover, the overall sealing performance is good. During the test, the sealing device is less likely to leak, thereby improving the accuracy of the test.

[0008] Optionally, an annular groove is formed on the surface of the sealing cover facing the prefabricated frame, and the annular groove is staggered with the sealing groove.

[0009] By adopting the above technical solution, sealing rings are embedded in both the annular groove and the sealing groove, thereby forming a secondary seal, improving the overall sealing of the device and improving the detection accuracy.

[0010] Optionally, two sealing covers are provided and are respectively located on the upper surface and the lower surface of the prefabricated frame, and the detection groove passes through the prefabricated frame.

[0011] By adopting the above technical solution, two sealing covers are placed one above and one below on both sides of the prefabricated frame, and the sealing material is tested from both sides, thereby improving the accuracy of the measurement.

[0014] Optionally, the support member includes a vertical rod and a horizontal rod, the vertical rod is vertically fixed between the upper frame and the lower frame, and the horizontal rod is horizontally arranged. There are four horizontal rods, and the horizontal rods are fixedly connected to the vertical rods in the same row at the same time.

[0015] By adopting the above technical solution, the support members support and connect the upper frame and the lower frame, and concrete is injected between the upper frame and the lower frame to seal the four sides of the prefabricated frame. The support members can also act as a steel cage in the concrete, thereby providing overall structural strength.

[0016] Optionally, a vertical angle steel is fixed between the upper frame and the lower frame, and the angle steel is arranged at the corners of the upper frame and the lower frame.

[0017] By adopting the above technical solution, the angle steel supports the corners of the upper frame and the lower frame and defines the edges. When concrete is filled between the upper frame and the lower frame, the angle steel can define the edge of the concrete to prevent collapse.

[0018] Optionally, a locking mechanism is provided between the sealing cover and the prefabricated frame.

[0019] By adopting the above technical solution, the locking mechanism enhances the connection strength between the sealing cover and the prefabricated frame, preventing the sealing cover from exploding due to excessive pressure of the introduced fluid.

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] An embodiment of the present application discloses a sealing device for testing the sealing properties of a material.

[0035] Example 1

[0036] Reference Figure 1 A sealing device for testing the sealing properties of materials includes a sealing cover 1 and a prefabricated frame 2. A testing slot 22 is defined in the center of the prefabricated frame 2 and extends through the frame. Two sealing covers 1 are provided, one on the upper and one on the lower surface of the frame 2. The two sealing covers 1 are connected by the testing slot 22. The prefabricated frame 2 is sealed around its perimeter with concrete, cement, or other materials to form a sealed device. Performance testing is then performed within the sealing material and the prefabricated frame 2.

[0037] Reference Figure 1 The sealing cover 1 has an outwardly extending connection edge 13 on the side facing the prefabricated frame 2. The sealing cover 1 is provided with an instrument port 14 and a pressure port 15. The instrument port 14 can be connected to a pressure gauge or flow meter to detect leakage in the sealing cover, depending on experimental requirements. The pressure port 15 is connected to an external fluid, which can be either a gas or a liquid, depending on experimental requirements.

[0038] The sealing cover 1 is also connected to a drain pipe 11, which is connected to a control valve. After the liquid test is completed, the operator can drain the liquid in the sealing cover 1 through the drain pipe 11 to prevent water from overflowing when the sealing cover 1 is opened.

[0039] Reference Figure 1 and Figure 2 The connecting edge 13 is provided with a plurality of locking holes 71 for connecting to the prefabricated frame 2. The side of the connecting edge 13 facing the prefabricated frame 2 is provided with an inwardly concave annular groove 12. An annular groove 12 is embedded with a sealing ring. The sealing ring can be made of silicone or other rubber materials as long as it is airtight. All locking holes 71 are located outside the annular groove 12.

[0040] Reference Figure 1 and Figure 3 As shown in FIGS. and, the prefabricated frame 2 includes an upper frame 3 and a lower frame 4, and the structures of the upper frame 3 and the lower frame 4 are the same. A number of locking holes 71 are also provided on the upper frame 3. The locking holes 71 on the upper frame 3 are in one-to-one correspondence with the locking holes 71 on the sealing cover 1, and a locking bolt 72 is inserted into the locking hole 71. The locking bolt 72 and the locking hole 71 form a locking mechanism for locking the sealing cover 1 and the prefabricated frame 2.

[0041] Reference Figure 1 and Figure 3 As shown in FIGS. and, an annular sealing groove 21 is provided on the surface of the upper frame 3 facing the sealing cover 1, and a sealing ring is also embedded in the sealing groove. All the locking holes 71 on the upper frame 3 are located inside the inner circle of the sealing groove 21. The sealing groove 21 is错开 from the annular groove 12 and the two do not cross and overlap. That is, two sealing rings are required to be filled into the annular groove 12 and the sealing groove 21 respectively to form a secondary seal, and then the sealing cover 1 is covered to perform a sealing performance test.

[0042] Reference Figure 3 As shown in FIG., the upper frame 3 is generally in the shape of a "mouth", and includes two vertical plates 31 and two horizontal plates 32. The vertical plates 31 and the horizontal plates 32 are perpendicular to each other and integrally connected. A vertical angle steel 6 is fixed at the corner where the vertical plate 31 and the horizontal plate 32 are connected. The upper end of the angle steel 6 is fixedly connected to the upper frame 3, and the lower end of the angle steel 6 is fixedly connected to the lower frame 4. The angle steel 6 includes a horizontal piece 62 and a vertical piece 61 that are perpendicular to each other. The edge of the vertical piece 61 is flush with the edge of the vertical plate 31, and the edge of the horizontal piece 62 is flush with the edge of the horizontal plate 32.

[0043] Reference Figure 3 As shown in FIG., a number of support members 5 are connected between the upper frame 3 and the lower frame 4, and the ends of the support members 5 do not extend into the detection groove 22. All the support members 5 are located directly below the vertical plates 31 and the horizontal plates 32.

[0044] Reference Figure 3 As shown in FIG., the support member 5 includes a number of vertical rods 51 and four horizontal rods 52. The vertical rods 51 are arranged side by side vertically directly below the vertical plates 31 and the horizontal plates 32 to connect the upper frame 3 and the lower frame 4. The four horizontal rods 52 are respectively located directly below the two vertical plates 31 and the two horizontal plates 32. One horizontal rod 52 is fixedly connected to all the vertical rods 51 in this row at the same time. The horizontal rods 52 and the vertical rods 51 are used to strengthen the connection strength between the upper frame 3 and the lower frame 4 and improve the stability.

[0045] It should be noted that the Chinese character "错开" in the original text is not accurately translated in the above content as there is no exact corresponding English word. It is translated as "错开" for the purpose of showing the original text structure. You may need to adjust it according to the actual situation to make the translation more accurate.The operating principle of a sealing device for testing material sealing properties according to an embodiment of the present application is as follows: an operator fills a sealing material into a test groove 22, then pours concrete from the outside of a prefabricated frame 2 inward, sealing the periphery of the prefabricated frame 2. A sealing cover 1 is placed on the prefabricated frame 2 and secured with locking bolts 72. The operator then fills the seal with fluid through the pressure port 15 on the sealing cover 1 to test the sealing properties of the material.

[0046] Example 2

[0047] The difference between the second embodiment and the first embodiment lies in the number of sealing covers 1 and the structure of the prefabricated frame 2: Figure 4 The sealing cover 1 is provided with a detection groove 22 with one end sealed and the other end facing the sealing cover 1.

[0048] Example 3

[0049] The difference between the third embodiment and the first embodiment is that the structure of the locking mechanism is different: Figure 5 The locking mechanism includes a locking pin 73 , which is fixed to the upper surface of the upper frame 3 , and is arranged along the length direction of the vertical plate 31 and the horizontal plate 32 .

[0050] Reference Figure 5 and Figure 6 The upper end of the locking pin 73 is tapered, and a horizontal connection hole 731 is formed on the locking pin 73. The direction of the connection hole 731 is parallel to the arrangement direction of the row of locking pins 73. That is, if the locking pin 73 is close to the horizontal plate 32, the connection hole 731 on the locking pin 73 is parallel to the length direction of the horizontal plate 32; if the locking pin 73 is close to the vertical plate 31, the connection hole 731 on the locking pin 73 is parallel to the length direction of the vertical plate 31.

[0051] Reference Figure 5 and Figure 6 The surface of the sealing cover 1 facing the prefabricated frame 2 is provided with a locking groove 74 that is opposite to the locking pin 73. The locking groove 74 is vertically arranged and can accommodate the locking pin 73. The sealing cover 1 is covered on the prefabricated frame 2, with the locking groove 74 and the locking pin 73 facing each other, and the locking pin 73 is inserted into the locking groove 74.

[0052] Reference Figure 5 and Figure 6 The sealing cover 1 is provided with a plurality of horizontally arranged sliding grooves 75. The ends of the sliding grooves 75 are connected to the locking grooves 74. The direction of the sliding grooves 75 is consistent with the direction of the connecting hole 731 on the locking pin 73. A locking rod 76 is horizontally slidably connected in the sliding grooves 75. A connecting spring 77 is connected between the locking rod 76 and the bottom of the sliding grooves 75. When the connecting spring 77 is in its natural state, the end portion of the locking rod 76 extends out of the sliding grooves 75 and is located in the locking grooves 74.

[0053] Reference Figure 5 and Figure 6 When the locking pin 73 is inserted into the locking groove 74, the end of the locking pin 73 squeezes the locking pin 73 rod, and the locking rod 76 gradually retracts into the sliding groove 75. When the locking pin 73 is fully inserted into the locking groove 74, the locking rod 76 is opposite to the connecting hole 731. At this time, the locking rod 76 is inserted into the connecting hole 731 under the action of the connecting spring 77, thereby locking it.

[0054] Reference Figure 5 and Figure 6 The sealing cover 1 is provided with four control holes 78, which are divided into two horizontal holes and two vertical holes. The two horizontal holes are respectively located in the two horizontal plates 32 and are parallel to the length direction of the horizontal plates 32. The two vertical holes are respectively located in the two vertical plates 31 and are parallel to the length direction of the vertical plates 31. The height of the vertical holes is lower than that of the horizontal holes and is staggered with the horizontal holes.

[0055] Reference Figure 5 and Figure 6 A control hole 78 is connected to the same row of sliding slots 75 adjacent to the control hole 78. A control rod 79 is horizontally slidably connected to the control hole 78. The control rod 79 is also fixedly connected to the same row of locking rods 76. That is, when the operator pulls the control rod 79, all the locking rods 76 in the same row will move and be inserted into or removed from the connection holes 731.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
