[0028] like Figure 1-7 As shown, a water system air tightness detection tool is used to detect the air tightness of the water system. The water system includes a fixed frame 100, and the fixed frame 100 is provided with a solenoid valve 200, a water inlet joint 300 and a water outlet joint 400. The solenoid valve 200 is used to control the connection or disconnection of the water inlet joint 300 and the water outlet joint 400. The air tightness detection tool includes a fixed seat 1, and the fixed seat 1 is provided with a limit component 2, a control component 3, a water inlet plugging component 4, a water outlet plugging component 5 and a connection component 6. The limit component 2 is used to install the fixed frame 100, and the fixed frame 100 is detachably connected to the limit component 2, and the water inlet plugging component 4, the water outlet plugging component 5 and the connection component 6 are respectively connected to the control component 3. The water outlet plugging component 5 can be connected to the water outlet joint 400 to plug the water outlet joint 400; the connecting component 6 can be connected to the solenoid valve 200 to control the electrical connection or disconnection between the solenoid valve 200 and the control component 3; the water inlet plugging component 4 can be connected to the water inlet joint 300 to plug the water inlet joint 300; the water inlet plugging component 4 is provided with an air inlet pipe 41, which is used for an external air source and a pressure gauge.

[0029] In specific operation, the fixing frame 100 is first placed on the limit assembly 2, so that the water system is installed on the fixing seat 1. Then, the water inlet blocking assembly 4, the water outlet blocking assembly 5 and the connecting assembly 6 are controlled by the control assembly 3 to work respectively; the water outlet blocking assembly 5 can be connected to the water outlet joint 400, so as to block the water outlet joint 400. The connecting assembly 6 can be connected to the solenoid valve 200, so that the solenoid valve 200 and the control assembly 3 are electrically connected; then the solenoid valve 200 is controlled by the control assembly 3 to work, so that the water inlet joint 300 is connected to the water outlet joint 400. The water inlet blocking assembly 4 can be connected to the water inlet joint 300, so as to block the water inlet joint 300. Then, an air source and a pressure gauge are connected to the air inlet pipe 41, and external gas is injected into the water system through the water inlet joint 300, passes through the solenoid valve 200, and finally flows into the water outlet joint 400; after standing for a period of time, the user can judge whether there is a leak in the water system by observing the changes in the value of the pressure gauge, thereby achieving the purpose of detecting the air tightness of the water system.

[0030] The air tightness testing tool is used to test the air tightness of the water system. There is no need to manually plug and unplug pipes or manually connect wires. The machine is used instead of manual labor, which can greatly improve the testing efficiency and reduce labor costs.

[0031] In this embodiment, the solenoid valve 200 is a normally closed solenoid valve 200, so the connection component 6 is required to enable the solenoid valve 200 to be opened; in other embodiments, if the water system reselects a normally open solenoid valve 200, the connection component 6 is not required to complete the air tightness detection of the water system.

[0032] like Figure 2 As shown, the limit assembly 2 includes two guide rails 21, which are arranged in parallel on the fixing seat 1 and are fixedly connected to the fixing seat 1 by screws respectively. The spacing between the two guide rails 21 is adapted to the width of the fixing frame 100, and the fixing frame 100 is slidably engaged with the guide rails 21 respectively. When installing the water system on the fixing seat 1, the fixing frame 100 can be inserted between the two guide rails 21 by holding the fixing frame 100, and the fixing frame 100 can be inserted into the fixing seat 1 by pushing the fixing frame 100 to slide on the guide rails 21. The fixing frame 100 can be clamped by the two guide rails 21, so that the water system is limitedly installed on the fixing seat 1. After the inspection is completed, the water system can be removed from the fixing seat 1 by simply pulling the fixing frame 100 out of the guide rails 21.

[0033] In order to limit the travel of the fixing frame 100 inserted into the fixing seat 1, a limit block 22 is provided on the fixing seat 1. The limit block 22 is used to limit the installation position of the fixing frame 100 on the fixing seat 1, and the side wall of the fixing frame 100 can abut against the limit block 22. When installing the water system, after the fixing frame 100 is inserted between the two guide rails 21, the fixing frame 100 is pushed to slide on the guide rails 21 until the fixing frame 100 abuts against the limit block 22, indicating that the fixing frame 100 slides to the preset installation position; the installation position of the fixing frame 100 is limited by the limit block 22, thereby improving the installation stability of the fixing frame 100 and the fixing seat 1, ensuring that the position of the water system is consistent each time it is installed, and improving the stability of the detection.

[0034] like Figure 3 As shown, the water outlet plugging assembly 5 includes a first plugging cylinder 51, which is fixedly mounted on the fixing seat 1, and is connected to the control assembly 3. A first plug 52 is provided on the output end of the first plugging cylinder 51, and the first plugging cylinder 51 can drive the first plug 52 to abut against or separate from the water outlet joint 400. When the water system is installed on the fixing seat 1 and an air tightness test is required, the first plugging cylinder 51 is controlled by the control assembly 3 to work, and the first plug 52 is driven to move toward the direction close to the water system until the first plug 52 abuts against the water outlet joint 400, so that the first plug 52 blocks the water outlet joint 400, thereby avoiding air leakage from the water outlet joint 400 during the test; after the test is completed, the first plugging cylinder 51 is controlled by the control assembly 3 to drive the first plug 52 to move away from the water system, so that the first plug 52 is separated from the water outlet joint 400.

[0035] like Figure 4As shown, the water inlet plugging assembly 4 includes a second plugging cylinder 42, which is fixedly mounted on the fixing seat 1, and is connected to the control assembly 3. A second plug 43 is provided on the output end of the second plugging cylinder 42. The second plugging cylinder 42 can drive the first plug 52 to abut or separate from the water outlet joint 400, and the air inlet pipe 41 is mounted on the second plug 43 and is connected to the second plug 43. When the water system is installed on the fixing seat 1 and needs to be tested for air tightness, the control component 3 controls the second plugging cylinder 42 to work, and drives the second plug 43 to move in the direction close to the water system, until the second plug 43 abuts against the water inlet joint 300, so that the second plug 43 blocks the water inlet joint 300, thereby avoiding air leakage from the water inlet joint 300 during the test; then the air inlet pipe 41 is connected to an external air source and a pressure gauge, and the external air source flows into the second plug 43 through the air inlet pipe 41, and then flows into the water system; then it is left to stand for a period of time, and by observing the value changes of the external pressure gauge, it can be determined whether there is air leakage in the current water system. After the test is completed, the control component 3 controls the second plugging cylinder 42 to drive the second plug 43 to move in the direction away from the water system, so that the second plug 43 is separated from the water inlet joint 300.

[0036] In order to improve the sealing performance of the second plug 43 and the water inlet joint 300, a sealing gasket 44 is provided in the second plug 43. When the second plugging cylinder 42 drives the second plug 43 to plug the water inlet joint 300, the sealing gasket 44 will be in sealing contact with the water inlet joint 300. By providing the sealing gasket 44, the sealing performance of the connection between the second plug 43 and the water inlet joint can be improved, thereby ensuring the stability of the airtight detection.

[0037] like Figure 5As shown, the connecting component 6 includes a connecting cylinder 61, which is fixedly mounted on the fixing seat 1 and connected to the control component 3. A sliding plate 62 is provided on the output end of the connecting cylinder 61, and a plurality of conducting probes 63 are provided on the sliding plate 62. Each conducting probe 63 is provided with a wire 64, and the wire 64 is connected to the control component 3. The connecting cylinder 61 can drive the conducting probe 63 to connect or separate with the solenoid valve 200. During specific operation, the control component 3 can connect the cylinder 61 to work, and the cylinder 61 drives the sliding piece 62 to move in the direction close to the water system, and the sliding piece 62 drives the conductive probe 63 to move together until the conductive probe 63 abuts against the terminal of the electromagnetic valve 200, so that the electromagnetic valve 200 is electrically connected to the control component 3 through the wire 64, and then the control component 3 can control the electromagnetic valve 200 to work; the control component 3 controls the electromagnetic valve 200 to work, so that the water inlet joint 300 and the water outlet joint 400 can be connected or disconnected, so as to detect the air tightness of the water system. After the detection is completed, it is only necessary to control the connection cylinder 61 to reset, which will drive the conductive probe 63 to move in the direction away from the water system, so that the conductive probe 63 is separated from the terminal of the electromagnetic valve 200.

[0038] In order to limit and guide the movement direction of the sliding piece 62, a guide block 11 is provided on the fixed seat 1, and a snap-in groove 65 is provided on the sliding piece 62, and the snap-in groove 65 is slidably snap-in with the guide block 11; when the cylinder 61 is turned on to work, the sliding piece 62 is driven to move, and the sliding piece 62 is limited by the guide block 11 and slides on the guide block 11; the movement direction of the sliding piece 62 can be limited by the cooperation between the guide block 11 and the snap-in groove 65, thereby ensuring that the sliding piece 62 can drive the conductive probe 63 to abut against the wiring terminal of the solenoid valve 200, thereby improving the stability of the detection.

[0039] like Figure 6 As shown, the control component 3 includes a control panel 31, the control panel 31 is connected to an external power supply, the control panel 31 is connected and fixed to the fixing base 1 through a support stud 32, the control panel 31 is respectively connected to the first plugging cylinder 51, the second plugging cylinder 42, the connecting cylinder 61 and the conducting probe 63, and a control switch 33 is provided on the control panel 31; by pressing the control switch 33, the control panel 31 can be used to control the operation of the first plugging cylinder 51, the second plugging cylinder 42, the connecting cylinder 61 and the conducting probe 63 respectively, thereby realizing the air tightness detection of the water system.

[0040] An indicator light 34 is provided on the control board 31, and the user can judge whether the control board 31 is powered on by observing the indicator light 34. During specific operation, when the control board 31 is connected to an external power source, the indicator light 34 will light up.

[0041] Working principle:

[0042] First, install the water system on the fixing base 1, align the fixing frame 100 with the guide rails 21, place the fixing frame 100 between the two guide rails 21, and push the fixing frame 100 to slide on the guide rails 21 until the side wall of the fixing frame 100 abuts against the limit block 22, so that the water cooling system is installed and fixed on the fixing base 1.

[0043] After the control board 31 is powered on, the indicator light 34 will light up; then, by pressing the control switch 33, the first blocking cylinder 51, the second blocking cylinder 42 and the connecting cylinder 61 can be controlled to work, the first blocking cylinder 51 drives the first plug 52 to block the water outlet joint 400, the second blocking cylinder 42 drives the second plug 43 to block the water inlet joint 300, and the connecting cylinder 61 drives the sliding piece 62 to drive the conducting probe 63 to connect with the wiring terminal of the solenoid valve 200; thereby, the control board 31 is electrically connected to the solenoid valve 200 through the wire 64; the solenoid valve 200 is controlled to work through the control board 31, so that the water inlet joint 300 is connected with the water outlet joint 400. Then, connect the air source and pressure gauge to the air inlet pipe 41, and inject gas into the air inlet pipe 41 through the external air source. The gas will pass through the solenoid valve 200 and be injected into the water system. After a certain amount of gas is injected, the air pressure value in the water system can be observed through the pressure gauge; then, let it stand for a while, and by observing the changes in the value on the pressure gauge, the air tightness of the current water system can be judged. After the detection is completed, press the control switch 33 again to control the first plugging cylinder 51, the second plugging cylinder 42 and the connection cylinder 61 to reset, so that the first plug 52 is separated from the water outlet joint 400, the second plug 43 is separated from the water inlet joint 300, and the conduction probe 63 is separated from the solenoid valve 200. Then, by pulling the fixing frame 100 to slide on the guide rail 21, the water system can be removed from the fixing seat 1.
