[0026] 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.
[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a pressure testing device, comprising: a support platform 1; a workbench 6 mounted on the top of the support platform 1 by bolts; a humidification tank 5 disposed above the workbench 6; a detection tube 8 disposed on the humidification tank 5, with a detection air tube 10 disposed at one end of the detection tube 8; connecting tubes 9 symmetrically fixed to the humidification tank 5; a rotary joint 12 disposed on one end of the detection air tube 10, with an external threaded connector 13 disposed at the end of the rotary joint 12 away from the detection air tube 10; a detection column 21 mounted on the top of the support platform 1 by bolts, with a first air tube 15 disposed on one side of the detection column 21; a connecting tee 16 disposed on one end of the first air tube 15, with a third air tube 19 disposed at one end of the connecting tee 16; and a needle tube 20 disposed on one end of the third air tube 19.
[0028] It should be noted that in this embodiment, the workbench 6 is securely installed on the top of the support platform 1 with bolts, the humidification tank 5 is placed on the workbench 6, and the support cylinder seat 7 is symmetrically installed on the top of the workbench 6 with bolts, so that the connecting pipe 9 and the support cylinder seat 7 are accurately matched. The support cylinder seat 7 not only provides better support for the humidification tank 5, but also seals the connecting pipe 9, creating good conditions for subsequent pressure testing. The second placement tray 4 set on the top of the support platform 1 is used to place the humidification tank 5 to be tested for easy access. The detection tube 8 is set on the humidification tank 5, and the detection gas tube 10 at one end of the detection tube 8 is connected to other parts of the device through a rotary joint 12. An external threaded connector 13 is provided at the end of the head 12 away from the detection air tube 10. An internal threaded connector 18 is fixed to the No. 2 air tube 17, which is fixed to one end of the connecting tee 16. Through the cooperation of the internal threaded connector 18 and the external threaded connector 13, a convenient and stable connection between the detection air tube 10 and the No. 2 air tube 17 is achieved. The detection column 21 is installed on the top of the support platform 1 by bolts. A detection water column 22 is installed inside the column. Multiple difference indicator lines 23 and level indicator lines 14 are provided on one side of the detection column 21 to visually display the changes in the water column during the detection process. A No. 1 air tube 15 is installed on one side of the detection column 21, and a connecting tee 16 is installed at one end of the No. 1 air tube 15. One end of the tee 16 is connected to a No. 3 air tube 19, and the syringe 20 is placed at one end of the No. 3 air tube 19, completing the initial setup of the entire detection device. Ensure that the Robert clamp 11 on the detection air tube 10 is in the open state to allow normal gas flow. Check whether it is installed correctly and ensure the sealing of the detection system. At this time, observe the water column in the detection column 21 and ensure that the water columns on both sides are level. When the water columns on both sides are level, slowly push the syringe 20 to allow gas to enter the detection column 21 through the No. 3 air tube 19, the tee 16, and the No. 1 air tube 15, thereby pushing the detection water column 22 upward. When the water column rises to the water level zone, stop pushing the syringe 20. Record the initial state of the water column and observe the situation of the test water column 22 in the difference zone. If the water column can maintain the humidification tank stable for 5 seconds in the difference zone, it indicates that the humidification tank 5 can maintain stability under the current pressure, and its pressure performance is initially judged to meet certain requirements. After the 1200cm water column maintains the humidification tank stable for 5 seconds in the difference zone, flip the humidification tank 5 and observe the changes in the water columns on both sides of the test column 21. If the water columns on both sides can return to being level, it indicates that the pressure of the humidification tank 5 is qualified. Then, put on the drip cup sleeve to complete the test. If the water column cannot return to being level, or if there is an abnormal situation of rapid drop during the stabilization process of the water column, the humidification tank 5 is judged to be a defective product and needs to be marked and isolated.
[0029] In one embodiment, such as Figures 1 to 5 As shown, one end of the connecting tee 16 is fixedly connected to a No. 2 air pipe 17, and an internally threaded connecting pipe 18 is fixedly connected to the No. 2 air pipe 17. The internally threaded connecting pipe 18 is matched with the externally threaded connector 13.
[0030] It should be noted that in this embodiment, the internal threaded connecting pipe 18 fixed to the No. 2 air pipe 17 cooperates with the external threaded connecting head 13 on the rotary joint 12, thereby realizing a convenient and stable connection between the detection air pipe 10 and the No. 2 air pipe 17, which facilitates the assembly and disassembly of the various components of the device and is beneficial for subsequent maintenance and replacement.
[0031] In one embodiment, such as Figures 1 to 5 As shown, it also includes a support cylinder seat 7, which is symmetrically installed on the top of the workbench 6 by bolts. The connecting pipe 9 cooperates with the support cylinder seat 7, and a through groove is provided on one side of the workbench 6.
[0032] It should be noted that in this embodiment, the support cylinder 7 is symmetrically installed on the top of the workbench 6 and cooperates with the connecting pipe 9, which provides better support for the humidification tank 5, seals the connecting pipe 9, and facilitates better pressure detection.
[0033] In one embodiment, such as Figures 1 to 5 As shown, a detection water column 22 is provided inside the detection column 21, multiple difference indicator lines 23 are provided on one side of the detection column 21, and a level indicator line 14 is provided on one side of the detection column 21.
[0034] It should be noted that in this embodiment, a detection water column 22 is set inside the detection column 21, which, together with multiple difference indicator lines 23 and level indicator lines 14, allows for intuitive observation of the changes in the water column during the detection process. By observing the water column's position in the difference zone, the pressure of the humidification tank 5 can be accurately determined, thus improving the accuracy and intuitiveness of the detection.
[0035] In one embodiment, such as Figures 1 to 5 As shown, a second placement tray 4 is provided on the top of the support platform 1, a first placement tray 3 is provided inside the support platform 1, and a collection box 2 is provided on one side of the support platform 1.
[0036] It should be noted that in this embodiment, a second placement tray 4 is set on the top of the support platform 1, and a first placement tray 3 is set inside. The second placement tray 4 is used to place the humidification tank 5 to be tested, and the first placement tray 3 is used to place the qualified humidification tank 5. A collection box 2 is set on one side to facilitate the collection of waste or defective products generated during the testing process.
[0037] In one embodiment, such as Figures 1 to 5 As shown, a Robert clip 11 is installed on the trachea 10.
[0038] It should be noted that in this embodiment, a Robert clamp 11 is provided on the detection trachea 10. During the detection process, the flow state of the gas in the detection trachea 10 can be controlled as needed. For example, when the gas does not need to pass through, the detection trachea 10 can be clamped by the Robert clamp 11, so as to flexibly control the detection process and meet different detection operation requirements.
