Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve testing technology, and in particular to a testing device for electromagnetic valve production. Background Technology

[0002] Solenoid valve manufacturing requires rigorous airtightness testing. Poor sealing can lead to media leakage, causing not only control malfunctions and increased energy consumption, but also potentially serious safety accidents in flammable or high-pressure conditions. Therefore, airtightness testing is a crucial step in ensuring reliable valve performance and safe operation.

[0003] However, technicians found certain shortcomings in the existing testing equipment used in solenoid valve production. When testing, the existing testing equipment requires sealing and connecting the two ports of the solenoid valve to the test gas circuit and supplying gas. However, since different models of solenoid valves have different pipe diameters and interface types, operators must frequently change the matching indirect connectors to complete the connection. This makes the installation process of the solenoid valve too cumbersome, reduces testing efficiency, and makes it difficult to quickly test different models of solenoid valves. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a testing device for solenoid valve production. Through the moving component and the connecting component, the connecting pipes on both sides of the solenoid valve can be quickly sealed and connected. The connecting component can adapt to connecting pipes of different diameters without the need to replace the indirect connector, which greatly simplifies the clamping operation and significantly improves the testing efficiency for different models of products.

[0006] To achieve the above objectives, the first aspect of this utility model provides a testing device for the production of solenoid valves, comprising: a fixed base plate, an air supply component, a connecting component, a moving component, and a supporting component, wherein the air supply component is disposed at the top of the fixed base plate, the connecting component is disposed on the outside of the air supply component, the moving component is disposed at the top of the fixed base plate and connected to the connecting component, and the supporting component is disposed at the top of the fixed base plate.

[0007] In addition, the solenoid valve manufacturing testing device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the air supply assembly includes an air compressor, a multi-way control valve, two air vents, and two pressure gauges. The air compressor is fixedly installed on the top of the fixed base plate, the multi-way control valve is fixedly installed on the top of the fixed base plate, and the air inlet pipe of the multi-way control valve is connected to the exhaust pipe of the air compressor.

[0009] Specifically, the connecting assembly includes two sleeves, two positioning rings, two corrugated pipes, two airbags, and two air pumps.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes a testing device for manufacturing solenoid valves according to an embodiment of the present invention, with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown in the figure, a testing device for solenoid valve production according to an embodiment of the present invention includes: a fixed base plate 1, an air supply component 2, a connecting component 3, a moving component 4, and a supporting component 5.

[0023] The air supply assembly 2 is located at the top of the fixed base plate 1. The air supply assembly 2 includes an air compressor 21, a multi-way control valve 22, two air pipes 23, and two pressure gauges 24. The air compressor 21 is fixedly installed at the top of the fixed base plate 1, the multi-way control valve 22 is fixedly installed at the top of the fixed base plate 1, and the air inlet pipe of the multi-way control valve 22 is connected to the air outlet pipe of the air compressor 21. The two air pipes 23 are respectively fixedly connected to the outside of the two air outlet pipes of the multi-way control valve 22, and the two pressure gauges 24 are respectively fixedly installed at the top of the corresponding air pipes 23.

[0024] It should be noted that the multi-way control valve 22 in this embodiment is specifically a pneumatic solenoid valve. The pneumatic solenoid valve has one air inlet, two air outlets and two air outlets. In the default state, the air inlet is connected to one of the air outlets, and when connected, the air outlet connected to that air outlet is closed. By adjusting the pneumatic solenoid valve, the two connecting pipes of the solenoid valve to be tested can be tested separately by supplying air.

[0025] The connecting component 3 is located on the outside of the air supply component 2, and the moving component 4 is located on the top of the fixed base plate 1, and the moving component 4 is connected to the connecting component 3.

[0026] The support assembly 5 is set at the top of the fixed base plate 1. The support assembly 5 includes multiple elastic telescopic rods 51, a support frame 52 and an anti-slip pad 53. The multiple elastic telescopic rods 51 are fixedly installed at the top of the fixed base plate 1, the support frame 52 is fixedly installed at the top of the multiple elastic telescopic rods 51, and the anti-slip pad 53 is fixedly connected to the bottom of the support frame 52.

[0027] It should be noted that the support component 5 can adjust the height of the solenoid valve by pressing down on the elastic telescopic rod 51, so that the height of the connecting pipes on both sides of the solenoid valve is aligned with the connecting component 3, which facilitates a more accurate connection of the connecting component 3.

[0028] Specifically, when it is necessary to perform an airtightness test on the solenoid valve, technicians will use the testing device used in the production of this solenoid valve.

[0029] First, the technician needs to place the solenoid valve to be tested on the support frame 52. The anti-slip pad 53 on the support frame 52 can prevent the solenoid valve from sliding on the support frame 52. The technician continuously presses down on the solenoid valve so that the connecting pipe on the solenoid valve is aligned with the connecting component 3.

[0030] Then, the technicians activated the moving component 4, which caused the moving component 4 to move the connecting component 3, so that the connecting component 3 was partially sleeved on the outside of the connecting pipe of the solenoid valve under test.

[0031] Next, the technicians can open the connecting component 3, so that the connecting component 3 is stably sealed and fixed on the outside of the connecting pipe of the solenoid valve under test, thus completing the fixed installation of the solenoid valve under test.

[0032] Finally, the technician can turn on the air compressor 21, select the connecting pipe corresponding to the solenoid valve under test through the pneumatic solenoid valve to fill it with air, and observe whether the pressure value of the corresponding pressure gauge 24 can remain stable, thereby determining whether the solenoid valve under test is leaking air, and completing the airtightness test of the solenoid valve.

[0033] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the moving component 4 includes a dust cover 41, a dual-axis motor 43, two lead screws 44, and two connecting brackets 45. The dust cover 41 is fixedly installed on the top of the fixed base plate 1, and two limiting grooves 42 are opened on the front side of the dust cover 41. The dual-axis motor 43 is fixedly installed inside the dust cover 41. The two lead screws 44 are respectively fixedly installed on both sides of the dual-axis motor 43. The two connecting brackets 45 are slidably connected to the inner side of the corresponding limiting grooves 42, and the two connecting brackets 45 are respectively threadedly connected to the corresponding lead screws 44.

[0034] Specifically, when it is necessary to connect the solenoid valve to be tested, the dual-output shaft motor 43 needs to be started first, so that the lead screws 44 on both sides of the dual-output shaft motor 43 rotate synchronously. The lead screws 44 drive the connecting frame 45, which is limited by the limiting groove 42, to move. The connecting frame 45 then drives the connecting component 3 to move. Through the observation of the technicians, when the connecting component 3 is sleeved on the outside of the connecting pipe of the solenoid valve to be tested, the operation of the moving component 4 is stopped, and the initial connection of the solenoid valve to be tested is completed.

[0035] The connecting assembly 3 includes two sleeves 31, two positioning rings 32, two corrugated pipes 33, two airbags 34, and two air pumps 35. The two sleeves 31 are slidably connected to the outside of the air inlets of the corresponding air pipes 23. The two positioning rings 32 are fixedly connected to one end of the corresponding sleeves 31. The two corrugated pipes 33 are fixedly connected between the corresponding positioning rings 32 and the air pipes 23. The two airbags 34 are installed inside the corresponding positioning rings 32. The two air pumps 35 are fixedly installed at the top of the corresponding sleeves 31, and the two air pumps 35 are connected to the corresponding airbags 34.

[0036] It should be noted that the bellows 33 in this embodiment has elasticity, which can maintain the sealed connection between the vent pipe 23 and the positioning ring 32 when the positioning ring 32 moves, and the sleeve 31 on the outside of the bellows 33 has protective support for the bellows 33, preventing the bellows 33 from expanding too much during inflation and affecting the accuracy of airtightness detection.

[0037] Specifically, the movement of the connecting frame 45 causes the positioning ring 32 to move synchronously. When the positioning ring 32 moves to the outside of the connecting pipe of the solenoid valve to be tested, the technician can turn on the air pump 35 to inflate the corresponding air bag 34. The air bag 34 gradually inflates and seals tightly against the outside of the connecting pipe, completing the quick connection with the connecting pipe of the solenoid valve to be tested.

[0038] In summary, the testing device for solenoid valve production of this utility model, through the movement of the moving component 4 driving the connecting component 3 to move, combined with the self-adaptive sealing of the inflatable airbag 34, realizes rapid sealing connection of solenoid valves with different pipe diameters, simplifies the connection steps of the solenoid valve under test, and significantly improves testing efficiency and versatility.
