Description

Technical Field

[0001] This utility model relates to the field of solenoid valve testing, and more particularly to a solenoid valve leakage detection fixture. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids, and belong to the actuator category. They are not limited to hydraulic or pneumatic applications; in industrial control systems, solenoid valves are used to adjust the direction, flow rate, speed, and other parameters of the medium.

[0003] The solenoid valve leakage detection tool disclosed in announcement number CN220136586U has a simple structure, is safe and energy-saving. It consists of a placement part, a clamping mechanism, a venting device, and a handle. The solenoid valve is placed on the placement part, and the clamping mechanism clamps the solenoid valve. When the solenoid valve is powered on, the valve head is closed. The venting device vents air into the solenoid valve. If soapy water is applied to the solenoid valve body and valve head, soap bubbles will be generated if the solenoid valve leaks. The clamping mechanism is equipped with a telescopic rod. The first connecting rod and the second connecting rod are connected by a screw thread. The screw can adjust the length of the telescopic rod to adapt to the length of different models of solenoid valves, thus having a wider range of applications.

[0004] However, the device has shortcomings. During the testing process, soapy water needs to be manually applied to the surface of the solenoid valve, which is a cumbersome process. In addition, manual application may result in some missed spots, affecting the accuracy and efficiency of the test. Utility Model Content

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] A preferred embodiment of the electromagnetic valve leakage detection gauge provided by this utility model is as follows: Figures 1 to 4 As shown: A solenoid valve leakage detection fixture includes a workbench 1, a shoulder 3 fixedly connected to the front of the top of the workbench 1, a clamping component 4 fixedly provided on one side of the shoulder 3, a leak detection component 2 fixedly provided on the inner wall of the workbench 1, and a drive component 5 fixedly provided at the rear of the top of the workbench 1, with the telescopic end of the drive component 5 fixedly connected to the clamping component 4.

[0026] In this embodiment, the leak detection component 2 includes a housing 201, which is fixedly connected to the inner wall of the workbench 1. An electric push rod 202 is fixedly connected to the bottom of the inner wall of the housing 201, and a support plate 203 is fixedly connected to the top of the electric push rod 202.

[0027] The above method involves using the support plate 203 to connect the inflated solenoid valve into the housing 201, immersing it in soapy water inside the housing 201 without any blind spots, and then raising the support plate 203. Compared with manually wiping with soapy water, this method can more comprehensively test the solenoid valve and improve the accuracy of the test.

[0028] In this embodiment, the drive component 5 includes a second cylinder 501, which is fixedly connected to the top of the worktable 1. A connecting block 502 is fixedly connected to the telescopic end of the second cylinder 501, and the front end of the connecting block 502 is fixedly connected to the clamping component 4.

[0029] The above scheme utilizes the second cylinder 501 to push the connecting block 502, thereby pushing the clamping assembly 4 to provide driving force for clamping the solenoid valve, facilitating subsequent testing operations.

[0030] In this embodiment, the clamping assembly 4 includes a first cylinder 401. A lower positioning plate 402 and an upper positioning plate 409 are fixedly connected to the front end of the first cylinder 401. A guide handle 403 is fixedly connected to the driving end of the first cylinder 401. A connecting handle 408 is rotatably connected to both ends of the guide handle 403. A half gear block 404 is rotatably connected to the end of the connecting handle 408 away from the guide handle 403. The half gear block 404 is rotatably connected to the lower positioning plate 402 and the guide handle 403. A slide bar 405 is meshed with one side of the half gear block 404. The upper end and lower end of the slide bar 405 are slidably connected to the front end of the upper positioning plate 409 and the front end of the lower positioning plate 402, respectively. A clamping block 407 is fixedly connected to the front end of the slide bar 405.

[0031] The above scheme utilizes the first cylinder 401 to drive the slide bar 405 to slide, thereby adjusting the distance between the two clamping blocks 407 to meet the clamping requirements of solenoid valves with different inner diameters, thus achieving greater practicality.

[0032] In this embodiment, a soft pad 406 is fixedly provided at the front end of the clamping block 407.

[0033] The above solution provides a buffer for the clamping process, preventing the clamping block 407 from directly contacting the solenoid valve body and causing damage.

[0034] In this embodiment, the lower positioning plate 402 and the upper positioning plate 409 are fixedly connected by bolts.

[0035] The above solution facilitates the disassembly of both components, allowing for cleaning and repair.

[0036] In this embodiment, the front end of the connecting block 502 is fixedly connected to the second cylinder 501, and connecting rods 503 are symmetrically fixedly connected to both sides of the front end of the connecting block 502. The connecting block 502 is fixedly connected to a collar 504 through the connecting rods 503, and the collar 504 is fixedly sleeved on the outer wall of the second cylinder 501.

[0037] The above solution makes the connection between the clamping component 4 and the connecting block 502 more stable, providing better support for the clamping operation of the clamping component 4.

[0038] In this embodiment, the leak detection component 2 is located directly below the two clamping components 4, and the electric push rod 202 and the support plate 203 are located in the middle of the inner wall of the housing 201.

[0039] The above scheme enables the support plate 203 to accurately receive the inflated solenoid valve and stably bring the solenoid valve into the housing 201 for immersion.

[0040] Working principle: When operating and using this utility model, as follows... Figures 1 to 4 As shown, during use, first inject an appropriate amount of soapy water into the housing 201, start the second cylinder 501, its telescopic end extends, driving the clamping component 4 closer to the solenoid valve, and then adjust according to the inner diameter of the solenoid valve. Start the first cylinder 401, its telescopic end drives the guide handle 403 to move, thereby driving the half gear block 404 to rotate at a fixed point, driving the slide bar 405 to slide along the front end of the lower positioning plate 402 and the upper positioning plate 409, thereby driving the adjustment of the distance between the two clamping blocks 407. The clamping components 4 on both sides of the two solenoid valves work together to clamp the solenoid valve, and then inflate it. After inflation is completed, start the electric push rod 202 to drive the support plate 203 to rise and contact the bottom of the solenoid valve, and then release the clamping components 4 on both sides, so that the electric push rod 202 drives the support plate 203 to descend, using the soapy water in the housing 201 to soak it without dead angles, and then raise the support plate 203. Finally, observe whether the solenoid valve is leaking air.

[0041] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
