Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve testing technology, specifically to an auxiliary tooling for electromagnetic valve testing. Background Technology

[0002] Solenoid valves are widely used in hydraulic control, water treatment, and industrial automation. Their sealing performance and pressure resistance directly determine the safety of the system and require rigorous testing and verification. However, current testing methods have significant shortcomings: First, diverse application scenarios lead to a wide variety of valve body specifications, traditional testing equipment has poor adaptability, requiring frequent program adjustments, and solenoid valve replacement is complex and inefficient. Second, most tooling lacks professional vibration damping and effective support measures, making external vibrations during testing susceptible to interference with pressure gauge readings and causing data deviations. To address these issues and meet the precise and efficient testing needs of various fields, the development of specialized testing auxiliary tooling is essential.

[0003] As disclosed in the patent announcement CN212567910U, a proportional solenoid valve testing auxiliary component includes a fixture connected to the proportional solenoid valve under test. The fixture also has a quick-connect coupling that connects to a pipeline. The fixture contains a first fluid channel and a second fluid channel, which are respectively used for fluid entry and exit from the fixture. Multiple quick-connect couplings can be provided and communicate with the first and second fluid channels. This invention also provides a proportional solenoid valve testing system. This invention ensures a stable connection between the proportional solenoid valve and the testing system, and enables testing of proportional solenoid valves under different flow rates and opening conditions. Furthermore, this invention has broad applicability and can be integrated with convenient control and testing systems.

[0004] Although the above solution enables the testing of proportional solenoid valves under the same flow rate and open conditions through quick couplings and the setting of the first and second fluid channels, this auxiliary tooling for solenoid valve testing lacks effective pipeline support and vibration damping measures during use. This can easily lead to pipeline or valve body vibration during testing, affecting the test results. In addition, the solenoid valve is fixedly connected to the fluid channel in this solution, making it inconvenient to replace the solenoid valve for batch testing. To address these issues, we propose an auxiliary tooling for solenoid valve testing that solves the problems of insufficient stability and inconvenient installation and removal of the solenoid valve. This improves the stability and convenience of the tooling, ensuring testing accuracy and efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tooling for testing solenoid valves, so as to solve the problems of insufficient stability and inconvenient installation and disassembly of solenoid valves in the existing auxiliary tooling for testing solenoid valves mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary tooling for testing a solenoid valve includes a test box. A test pipe is fixedly installed inside the test box. An inlet is fixedly provided at one end of the test pipe, and an outlet is fixedly provided at the other end. A solenoid valve is fixedly installed on the outside of the test pipe. A first shut-off valve and a pressure gauge are fixedly installed on the outside of the inlet, and a second shut-off valve is fixedly installed on the outside of the outlet.

[0008] As a further embodiment of this utility model: a first flange is fixedly provided at the bottom of the solenoid valve, and a second flange is fixedly provided at the test pipe connection port. The first flange and the second flange are fixedly connected by bolts, and a silicone sealing gasket is fixedly installed between the first flange and the second flange.

[0009] As a further embodiment of this utility model: several supports are fixedly arranged on the bottom surface of the test box, and an arc-shaped bracket is fixedly arranged on the top of the supports. The top surface of the arc-shaped bracket supports the bottom side of the test pipe, and a rubber anti-slip pad is fixedly pasted on the top surface of the arc-shaped bracket. There are no fewer than two arc-shaped brackets, and they are evenly distributed on the bottom side of the test pipe.

[0010] As a further embodiment of this utility model: U-shaped plates are fixedly installed on both sides of the bottom end of the test box, and a fixed mounting plate is fixedly connected to the bottom of the U-shaped plates through a spring damper. There are four U-shaped plates, and the four U-shaped plates are fixed horizontally and symmetrically about the center line of the test box on the bottom side of the test box. Several reserved fixing holes are opened inside the fixed mounting plate.

[0011] As a further improvement of this utility model: the outer surfaces of the inlet and outlet are both provided with external threads, and the test pipe is made of stainless steel or copper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This auxiliary tooling for testing solenoid valves, with its matching first flange, second flange, silicone gasket, and bolts, facilitates quick installation and removal of solenoid valves by testing personnel, while ensuring the stability and sealing of the connection between the solenoid valve and the test pipeline, thus improving testing efficiency.

[0014] This auxiliary tooling for testing solenoid valves provides effective support for the pressure-bearing section of the test pipeline by fixing several supports and arc-shaped brackets on the bottom side of the test pipeline. In conjunction with multiple spring dampers connected between the bottom side of the test box and the fixed mounting plate, the interference caused by the external environment and the solenoid valve's own vibration can be effectively reduced during the testing process, thereby improving the test accuracy and ensuring the test results.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example: An auxiliary tooling for testing solenoid valves, such as... Figures 1-3As shown, the test includes a test box 1, inside which a test pipe 2 is fixedly installed. One end of the test pipe 2 is fixedly provided with an inlet 3, and the other end is fixedly provided with an outlet 4. A solenoid valve 5 is fixedly installed on the outside of the test pipe 2. A first shut-off valve 6 and a pressure gauge 7 are fixedly installed on the outside of the inlet 3. A second shut-off valve 8 is fixedly installed on the outside of the outlet 4. A first flange 13 is fixedly provided at the bottom of the solenoid valve 5. A second flange 14 is fixedly provided at the connection port of the test pipe 2. The first flange 13 and the second flange 14 are fixedly connected by bolts 15. A silicone sealing gasket 16 is fixedly installed between the first flange 13 and the second flange 14. The outer surfaces of the inlet 3 and the outlet 4 are both provided with external threads 19. The test pipe 2 is made of stainless steel or copper.

[0023] In this embodiment, the solenoid valve 5 to be tested is fixed to the test pipe 2 via a flange structure. External fluid is introduced through the threaded inlet 3, and its flow is controlled by the first shut-off valve 6. The pressure gauge 7 monitors the inlet pressure. After flowing through the solenoid valve 5, the fluid is discharged through the outlet 4, and the outlet state is regulated by the second shut-off valve 8. By operating the solenoid valve and combining pressure changes with fluid flow, its sealing performance, response performance, and other indicators can be tested. The silicone sealing gasket 16 ensures no leakage at the connection points, and the stainless steel or copper pipe ensures test stability.

[0024] like Figures 2-4 As shown, U-shaped plates 9 are fixedly installed on both sides of the bottom of the test box 1. The bottom of the U-shaped plates 9 is fixedly connected to the mounting plate 11 through the spring damper 10. There are four U-shaped plates 9, which are horizontally symmetrical about the center line of the test box 1 and fixed on the bottom side of the test box 1. Several pre-reserved fixing holes 12 are opened inside the mounting plate 11. Several supports 17 are fixedly installed on the bottom surface of the test box 1. Arc-shaped brackets 18 are fixedly installed on the top of the supports 17. The top surface of the arc-shaped brackets 18 supports the bottom side of the test pipe 2. Rubber anti-slip pads are fixedly pasted on the top surface of the arc-shaped brackets 18. There are no fewer than two arc-shaped brackets 18, which are evenly distributed on the bottom side of the test pipe 2.

[0025] In this embodiment, during use, the fixture is first fixed through the pre-drilled fixing holes 12 on the mounting plate 11. External fluid enters through the inlet 3, the first shut-off valve 6 controls the flow, and the pressure gauge 7 measures the inlet pressure. The arc-shaped bracket 18 on top of the support 17 inside the test box 1, in conjunction with a rubber anti-slip pad, firmly supports the test pipe 2. After flowing through the solenoid valve 5, the fluid exits from the outlet 4, and the second shut-off valve 8 controls the outlet status. If there is vibration, the four sets of symmetrical U-shaped plates 9 at the bottom of the test box 1 are damped by spring dampers 10 to ensure fluid stability, thereby testing the performance of the solenoid valve.

[0026] In this embodiment, an auxiliary tooling for testing a solenoid valve is used. First, the solenoid valve 5 is fixed to the outside of the test pipe 2 using the first flange 13, the second flange 14, and bolts 15. The inlet 3 is connected to an external pressurized water source, and the outlet 4 is connected to an external drainage pipe. Then, the second shut-off valve 8 of the outlet 4 is closed, and the first shut-off valve 6 is opened, allowing pressurized water to flow into the test pipe 2. The water pressure inside the test pipe 2 is monitored by observing the pressure gauge 7, while simultaneously observing whether there are any abnormalities in the open solenoid valve 5. When the test pipe 2 gradually rises to the target water pressure, the external pressurized water source and the first shut-off valve 6 outside the inlet 3 are closed, and the solenoid valve 5 is then closed. Finally, the second valve of the outlet 4 is opened, and continuous observation is made to check whether there is any liquid leakage, in order to test the sealing effect and pressure resistance of the valve body.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
