[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0024] Example:
[0025] As attached Figure 1 To Attachment Figure 4 As shown:
[0026] The utility model provides a valve core air tightness testing device, including an installation back plate 11, a control component is arranged on one side of the installation back plate 11, the control component includes an air filter 21 and a manual valve 22, the air filter 21 and the manual valve 22 are arranged on one side of the installation back plate 11, the top of the air filter 21 is connected to the manual valve 22 through a first air pipe 23, to ensure that the gas can be fully purified before entering the test system, to ensure the connectivity and stability of the air path, and to avoid the test deviation caused by the unstable air source; a test component is also arranged on one side of the installation back plate 11, the test component includes a limiting bottom mold 31 on which two groups of valve cores 12 to be tested can be placed, the test component is installed on one side of the installation back plate 11, and is used to fix and position the valve core 12 to be tested.
[0027] Please refer to Figure 1 and Figure 2As shown, in addition to the air filter 21 and the manual valve 22, the control component also includes a pressure gauge 24 and an air pressure regulating knob 25, wherein the pressure gauge 24 is installed on the top of the air filter 21 to monitor the pressure of the air source in real time, and the air pressure regulating knob 25 is arranged on one side of the pressure gauge 24, so that the operator can adjust the air pressure accurately according to actual needs to ensure the stability of the air source during the test; at the same time, an air inlet pipe 26 is also connected to the top of the air filter 21, one end of which is connected to the air source pipeline of the workshop, and can directly obtain the required gas from the compressed air system of the workshop.
[0028] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, two groups of slide rails 32 are provided on one side of the mounting back plate 11, and these slide rails 32 allow two groups of slidable sliding blocks 33 to move freely thereon; one side of the connecting plate 34 is connected to the two groups of sliding blocks 33, and the other side of the connecting plate 34 is fixedly installed with the limiting bottom mold 31; the sliding mechanism is utilized, so that the connecting plate 34 can be displaced accordingly with the position of the sliding block 33, providing a stable foundation for subsequent testing and inspection work.
[0029] Please refer to Figure 3 and Figure 4 As shown, a quick push-pull clamp 35 is also provided on one side of the connecting plate 34, which improves the convenience and versatility of the test device; two groups of through holes are opened at the bottom of the quick push-pull clamp 35, and two groups of gas injection joints 39 are installed respectively, which can be directly connected to the two groups of valve cores 12 to be tested. At the same time, the tops of the two groups of gas injection joints 39 are connected to the manual valve 22 through two groups of third air pipes 36, so as to realize the delivery and control of the air source; the operator only needs to place the part to be tested on the limiting bottom mold 31, and then fix it with the quick push-pull clamp 35, so as to realize the rapid test of valve cores 12 of different models, which not only greatly reduces the preparation work before the test, but also overcomes the defects of traditional test tooling in versatility, and effectively saves the investment cost of enterprises in tooling research and development and manufacturing.
[0030] Please refer to Figure 4As shown, the test assembly also includes a propulsion cylinder 37, which is installed on one side of the mounting back plate 11. The top of the propulsion cylinder 37 is connected to the manual valve 22 through a second air pipe 38, and can drive its pneumatic rod to drive the two sets of sliding blocks 33 to move downward, thereby driving the entire connecting plate 34 to sink. In this way, the valve core 12 to be tested will be completely immersed in the water reservoir 13 on one side of the mounting back plate 11; next, the operator only needs to control the manual valve 22 to quickly inject gas into the two sets of second air pipes 38, so that it enters the inside of the valve core 12 to be tested through two sets of gas injection joints 39, so that the pressure gauge 24 can clearly display the air tightness of the valve core 12, and observing whether bubbles emerge in the water reservoir 13 can also intuitively reflect the sealing state of the valve core 12; this simple and efficient testing method not only gets rid of the dependence on complex instruments, but also can greatly improve the judgment accuracy of the operator and avoid the deviation of the test results caused by inconsistent manual operations.
[0031] Specific usage and function of this embodiment: When using the device, the operator first needs to connect the air inlet pipe 26 to the workshop air source to ensure sufficient and stable gas supply. The air pressure output by the air filter 21 can be adjusted to a set value suitable for testing through the air pressure adjustment knob 25; next, the operator needs to place the valve core 12 to be tested into the limiting bottom mold 31, and fix it with a quick push-pull clamp 35 connected to the connecting plate 34; this can ensure that the valve core 12 can maintain the correct position and posture during the entire test process.
[0032] Then, through the operation of the manual valve 22, the propulsion cylinder 37 drives the two sets of sliding blocks 33 to sink, thereby causing the connecting plate 34 and the limiting bottom mold 31 to move downward. In this way, the valve core 12 to be tested will be completely immersed in the water reservoir 13 on one side of the mounting back plate 11; in this state, the operator only needs to operate the manual valve 22 again to quickly inject compressed air into the interior of the valve core 12. At this time, the pressure gauge 24 will display the pressure change. At the same time, observing whether bubbles emerge in the water reservoir 13 can intuitively reflect the air tightness of the valve core 12.
[0033] If the test result shows that the valve core 12 is well sealed, the operator only needs to turn the manual valve 22 again to allow the thrust cylinder 37 to drive the connecting plate 34 and the limiting bottom mold 31 to rise and reset, and then take out the tested valve core 12. This simple and efficient testing method not only greatly improves the test speed, but also ensures the accuracy of the test results through intuitive observation indicators, effectively avoiding deviations caused by human operating errors.
