[0050] This invention proposes an electromagnetic pressure relief valve pressure resistance and sealing performance detector for use in the pressure resistance and sealing performance testing process of electromagnetic pressure relief valves. This invention does not limit the type of pressure relief valve to be tested, but the structure of the workbench 1, booster air pump 2, inverted U-shaped frame 13, pressure locking module 3, electromagnetic pressure relief valve discharge detection seat 4, leakage display module 5, and drive module 6 is particularly suitable for testing the performance of electromagnetic pressure relief valves.

[0051] In general, the electromagnetic pressure relief valve pressure sealing tester proposed in this utility model mainly includes: a workbench 1, a booster air pump 2, an inverted U-shaped frame 13, a material pressing and locking module 3, an electromagnetic pressure relief valve discharge detection seat 4, a leakage display module 5, and a drive module 6. (See also...) Figure 1 It shows the arrangement of the workbench 1, booster air pump 2, inverted U-shaped frame 13, material pressing and locking module 3, electromagnetic pressure relief valve discharge detection seat 4, leakage display module 5 and drive module 6.

[0052] When using the electromagnetic pressure relief valve pressure sealing tester proposed in this utility model, after energizing the connector of the electromagnetic pressure relief valve to be tested, a sealing ring 43 is put on one side of the valve. Then, the valve is placed in the valve body placement groove 42. The electromagnetic pressure relief valve is vertical so that the valve is directly facing the hollow round tube 44. The reversing valve 61 is moved so that the drive cylinder 31 drives the cylinder arm 32 to press down and put the top of the valve into the hollow round tube 44. After the sealing ring 43 is locked in the sealing groove, the duckbill foot valve 62 is stepped on so that the booster air pump 2 injects air into the pressurization port 45 through the air pipe. The value in the air pressure test gauge 52 is read to determine whether the valve body has leakage under a specific air pressure.

[0053] The workbench 1 is provided with support columns 11 around its bottom, and a gauge placement slot 12 is provided in the center of the top of the workbench 1. A booster air pump 2 is bolted to one side wall of the workbench 1. A pair of air outlet connectors 21 are provided on one side of the booster air pump 2. The pair of air outlet connectors 21 supply power to the drive cylinder 31 and the pressurization interface 45.

[0054] The aforementioned pressure locking module 3 is bolted to the center of the top of the inverted U-shaped frame 13. The pressure locking module 3 includes a drive cylinder 31, a cylinder arm 32, and a protective sleeve 33. The drive cylinder 31 is bolted to the center of the top of the inverted U-shaped frame 13. The cylinder arm 32 passes through the bottom of the drive cylinder 31. The bottom of the cylinder arm 32 extends vertically downward through the inverted U-shaped frame 13 toward the worktable 1. The protective sleeve 33 is fitted onto the bottom of the cylinder arm 32 to prevent indentations when limiting the electromagnetic pressure relief valve.

[0055] The aforementioned electromagnetic pressure relief valve discharge test seat 4 is located directly below the pressure locking module 3. The electromagnetic pressure relief valve discharge test seat 4 is placed within the fixture placement slot 12. The electromagnetic pressure relief valve discharge test seat 4 includes: a cylindrical iron block 41, a valve body placement slot 42, and a seal.

A valve body placement slot 42 is formed at the center of the top of the cylindrical iron block 41, with a sealing groove at the top. A sealing ring 43 is fitted inside the sealing groove. It should be noted that the sealing ring 43 is only used to improve the sealing within the valve body placement slot 42 during testing, allowing for more accurate measurement of the electromagnetic pressure relief valve's leakage. However, even without the sealing ring 43, leakage during testing can be detected by observing the pressure gauge 52. A change in the pressure gauge 52 indicates leakage in the electromagnetic pressure relief valve. A hollow tube 44 passes through the bottom of the cylindrical iron block 41, communicating with the valve body placement slot 42. The bottom of the hollow tube 44 passes through the fixture placement slot 12. Extending to the bottom of the workbench 1, a pressurization port 45 is threadedly connected to the bottom of the hollow round tube 44, and a leakage output port 46 is set on one side of the cylindrical iron block 41. The bottom of the leakage output port 46 passes through the cylindrical iron block 41 and communicates with the valve body placement groove 42.

[0057] The leakage display module 5 is arranged on one side of the top of the inverted U-shaped frame 13 by bolt connection, one side of the bottom of the leakage display module 5 is connected with one side of the electromagnetic pressure relief valve discharge detection seat 4 through an air pipe, and the leakage display module 5 comprises an L-shaped mounting seat 51 and an air pressure detection table 52, wherein the L-shaped mounting seat 51 is arranged at the top end of the inverted U-shaped frame 13 by bolt connection, the L-shaped mounting seat 51 is arranged on one side of the driving cylinder 31, and the air pressure detection table 52 is arranged on one side of the L-shaped mounting seat 51 by bolt connection, one side of the bottom of the air pressure detection table 52 is provided with a pressure input port 53, and the pressure input port 53 and the leakage output interface 46 are connected through an air pipe.
