Description

Technical Field

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

[0002] With the continuous development and widespread adoption of electro-hydraulic control systems in the industrial field, solenoid valves, as the core control components of these systems, are finding increasingly wider applications, leading to a significant increase in maintenance demands and a growing trend towards batch operations. After solenoid valve maintenance, pressure testing is essential to ensure their sealing performance and operational reliability. The performance of the pressure testing fixture directly determines the efficiency and quality of the testing process. A well-designed and easy-to-operate pressure testing fixture can significantly shorten the time required for a single test, improve the overall testing efficiency after batch maintenance, and is crucial for ensuring the stable operation of electro-hydraulic control systems. However, the traditional solenoid valve pressure testing fixtures widely used in the market (hereinafter referred to as "old fixtures") have obvious defects and are difficult to meet the high-efficiency testing needs of batch repair scenarios. The main problems are as follows: the fixing operation is cumbersome and the safety is insufficient. When fixing the solenoid valve, the old fixtures must tighten four screws to achieve reliable fixation. The operation steps are numerous and time-consuming, which seriously restricts the testing efficiency. If all four screws are not tightened properly, leakage is very likely to occur during the pressure test. This will not only affect the accuracy of the test results, but may also cause safety accidents due to sudden pressure changes, posing a significant safety hazard.

[0003] In addition, when testing and debugging the solenoid valve, the staff needs to operate and observe through two specific holes preset on the electromagnet. However, the design of these holes limits the observation angle, making it difficult for the staff to clearly and quickly grasp the key status information during the debugging process. This results in the inability to adjust the debugging parameters in a timely manner to achieve the expected debugging effect, which greatly prolongs the debugging cycle and further reduces the overall testing efficiency.

[0004] Therefore, there is an urgent need for a solenoid valve pressure testing fixture that is simple in structure, easy to operate, highly safe, and has high debugging efficiency, in order to solve the problems of low efficiency and poor safety of solenoid valve pressure testing in current batch maintenance scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a solenoid valve pressure testing fixture with a simple structure, convenient positioning and connection between the solenoid valve and the fixture, strong stability and high safety during testing, and effective improvement of testing efficiency.

[0006] The present invention adopts the following technical solution: A pressure testing fixture for a solenoid valve includes a pressure testing fixture body, a pressure cover is provided on the pressure testing fixture body, an accommodating space is formed in the middle of the pressure cover, a fixing part is provided on the top of the pressure cover, and the fixing part can be adjusted to move into or out of the accommodating space in a vertical direction; a positioning part is provided on the pressure testing fixture body below the pressure cover.

[0007] Preferably, the pressure cap is detachably connected to the pressure testing fixture body.

[0008] Preferably, the pressure cap and the test pressure fixture body are detachably connected by screws.

[0009] Preferably, the accommodating space includes two interconnected upper and lower parts, wherein the width of the upper part of the accommodating space is smaller than the width of the lower part.

[0010] Preferably, two positioning parts are provided.

[0011] Preferably, the positioning part is detachably connected to the test pressure fixture body.

[0012] Preferably, the positioning part is a positioning screw threaded onto the body of the pressure testing fixture.

[0013] Preferably, the positioning part is 5mm higher than the end face of the test pressure fixture body.

[0014] Preferably, the fixing part is a clamping screw, and the top of the pressure cover has a threaded hole through which the clamping screw is threaded.

[0015] Preferably, the pressure testing fixture body is provided with a pilot filter element.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a positioning part protruding on the body of the pressure testing fixture, which can directly cooperate with the mounting hole on the solenoid valve to complete the initial positioning without repeatedly calibrating the position of the solenoid valve; at the same time, the accommodating space formed in the middle of the pressure cap can quickly limit the solenoid valve, and with the fixing part on the top of the pressure cap that can be adjusted in the vertical direction, the solenoid valve can be reliably fixed simply by adjusting the fixing part to move into the accommodating space, which replaces the tedious operation of tightening four screws one by one in the traditional fixture, significantly shortening the single fixing time and effectively adapting to the high-efficiency testing needs in batch maintenance scenarios.

[0017] Furthermore, this utility model, through a multi-coordinated structure of "preliminary positioning of the positioning part + limiting of the accommodating space + vertical adjustment and fixing of the fixing part", can ensure that the solenoid valve always maintains a stable and accurate fixed state during the testing process, greatly reducing the risk of leakage caused by insecure fixing, avoiding safety hazards caused by sudden pressure changes from a structural perspective, and improving the safety of pressure testing operations. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the structure of an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the pressure testing fixture body in an embodiment of this application. Detailed Implementation

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 2 As shown, the solenoid valve 6 pressure testing fixture of this utility model includes a pressure testing fixture body 1, on which a pressure cover 2 is provided. The pressure cover 2 is preferably connected to the pressure testing fixture body 1 by screws on both sides, which facilitates the disassembly and installation of the entire fixture and provides convenience for subsequent targeted replacement of parts, reducing the difficulty of inspection and maintenance. Targeted replacement also reduces the cost of inspection and maintenance. A receiving space 3 is formed in the middle of the pressure cover 2, and a fixing part 4 is provided on the top of the pressure cover 2. The fixing part 4 can be adjusted vertically to move into or out of the receiving space 3. A positioning part 5 protrudes from the pressure testing fixture body 1 below the pressure cover 2. During operation, the solenoid valve 6 is placed within the accommodating space 3. Initial positioning and connection are achieved using the mounting hole at the bottom of the solenoid valve 6 and the positioning part 5. Subsequently, the fixing part 4 is adjusted to move downwards and press against the upper part of the solenoid valve 6, thus achieving positioning and fixation. This replaces the tedious operation of tightening four screws individually using traditional tooling, significantly shortening the single-session fixing time and effectively adapting to the high-efficiency testing needs of batch repair scenarios. It also avoids the problem of leakage or even safety accidents during pressure testing caused by screws not being properly tightened, which is a consequence of traditional tooling relying on multiple screws for fixation, effectively improving the safety of the testing.

[0020] Furthermore, in this embodiment, the accommodating space 3 includes upper and lower parts that are connected in a conductive manner. The upper part of the accommodating space 3 is narrower than the lower part. The upper space is used for pressure testing of the vertical solenoid valve 6, while the lower space is used for pressure testing of the horizontal solenoid valve 6, thus expanding the applicability of this utility model and enhancing its practical performance. In this embodiment, the width of the upper part of the accommodating space 3 is approximately 0.2 mm wider than the width of the vertical solenoid valve 6, and the width of the lower part is approximately 0.2 mm wider than the width of the horizontal solenoid valve 6. This allows for better fixation of the solenoid valve 6 and prevents it from swinging to both sides within the accommodating space 3. The overall height of the accommodating space 3 is higher than the height of the vertical solenoid valve 6, providing operating space for the installation of the solenoid valve 6 and the adjustment of the fixing part 4.

[0021] Furthermore, in this embodiment, two positioning parts 5 are preferably provided to correspond and match with the mounting holes on the solenoid valve 6, while ensuring the stability of the solenoid valve 6 installation. Each positioning part 5 is preferably 5mm higher than the top end face of the pressure testing fixture body 1 to facilitate positioning and connection with the mounting holes on the solenoid valve 6 and avoid errors. The positioning part 5 is detachably connected to the pressure testing fixture body 1 to increase the flexibility of the entire fixture application. In addition, the positioning part 5 is preferably a positioning screw threaded onto the pressure testing fixture body 1, which has a simple structure, readily available parts, low cost, and convenient operation.

[0022] Furthermore, in this embodiment, the fixing part 4 preferably adopts a clamping screw. The top of the pressure cover 2 has a threaded hole, and the clamping screw is threaded in the threaded hole. By rotating the clamping screw, it can be moved in or out of the accommodating space 3, thereby completing the positioning and fixing of the internal solenoid valve 6.

[0023] Furthermore, in this embodiment, the pressure testing fixture body 1 is also equipped with a pilot filter element 7. The pilot filter element 7 is a product of the prior art. The pilot filter element 7 is a high-precision filter when supplying liquid to the solenoid valve 6. After the liquid passes through this pilot filter element 7, it passes through the solenoid valve 6, which can filter the emulsion entering the solenoid valve 6 and avoid problems and rework due to the cleanliness of the emulsion. In actual working conditions, a connecting pipe is provided between the pilot filter element 7 and the solenoid valve 6. In order to facilitate the demonstration of the main structure to be protected in this application, the connecting pipe is not shown in the drawings.

[0024] In use, the solenoid valve 6 is connected to the positioning part 5 through the accommodating space 3 in the middle of the pressure cap 2. Then, the fixing part 4 is adjusted to fix the solenoid valve 6. This invention, through a multi-layered structure of "preliminary positioning by the positioning part 5 + limiting by the accommodating space 3 + vertical adjustment and fixing by the fixing part 4," ensures that the solenoid valve 6 remains stable and precisely fixed during testing, significantly reducing the risk of leakage due to insecure fixing. It also avoids safety hazards caused by sudden pressure changes from a structural perspective, improving the safety of pressure testing operations. Because the solenoid valve 6 is stably fixed, the electromagnet part in front of the solenoid valve 6 can be removed before debugging and reinstalled after the pressure test and debugging are completed, further improving the convenience of adjustment. This avoids the problem in existing technologies where operators need to operate and observe through two pre-set holes on the electromagnet, but the design of these holes limits the observation angle, making it difficult for operators to clearly and quickly grasp key status information during debugging, resulting in the inability to adjust debugging parameters in a timely manner to achieve the expected debugging effect. This effectively shortens the debugging cycle and further improves the overall testing efficiency.
