Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum leak detection technology, specifically a helium injection device for magnetohydrodynamic ATMs. Background Technology
[0002] Magnetofluids (ATMs) refer to magnetic nanoparticles coated or modified with surfactants, highly uniformly dispersed in a carrier liquid to form a stable, functionalized colloidal solution, also known as ferrofluids. Magnetofluids are a novel type of liquid functional material, possessing both the magnetism of solid materials and the fluidity of liquid materials, along with unique optical, thermal, and magnetic properties, thus exhibiting high development value. Currently, during the production of magnetofluid components, leak detection is required. This leak detection process utilizes a helium injection device. Specifically, helium gas is injected onto the surface of the component using this device. If a leak is detected, the helium gas enters and diffuses through the leak, then is detected by a helium mass spectrometer.
[0003] Currently, most helium injection devices require a fixed injection pipe length to ensure the injection range meets testing needs. This allows for injection testing of the workpiece at any angle. While the pipe length can be adjusted as needed, longer pipes can appear cluttered when not in use, and their length is difficult to adjust. Furthermore, most devices lack a structure for storing the injection pipes, leaving them scattered around, occupying space and creating a messy appearance, thus reducing their practicality.

[0020] 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.
[0021] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution: a helium injection device for a magnetohydrodynamic ATM, including a high-pressure helium cylinder 1. A constant pressure valve body and a rapid exhaust valve are connected sequentially from bottom to top on the top of the high-pressure helium cylinder 1. In this example, the constant pressure valve body and the rapid exhaust valve are existing technologies, so they will not be described in detail. One end of the rapid exhaust valve is connected to a nozzle 3. Two pipe clamps 13 are symmetrically arranged on the outside of the high-pressure helium cylinder 1, with one end of each clamp 13 movably connected and the other end connected by a fixing component. A storage mechanism is fixedly connected to one side of the pipe clamp 13. The storage mechanism includes a storage box 4, which is fixedly connected to the pipe clamp 13. A door 14 is connected to one side of the storage box 4 via a hinge. The storage box 4 is divided into two drive chambers and one storage chamber. The drive chambers are located on both sides of the storage chamber. A hollow shaft 5 is rotatably installed in the storage chamber and the drive chamber. A take-up reel 7 is sleeved on the outside of the hollow shaft 5 inside the storage chamber. A second nozzle 3 is spirally wound on the outside of the take-up reel 7. One end of the second nozzle 3 passes through the take-up reel 7 and communicates with the hollow shaft 5. In this example, the storage mechanism also includes a connector 6. One end of the hollow shaft 5 extends outside the storage box 4 and is rotatably connected to the connector 6. The other end of the connector 6 is connected to one end of the nozzle 2. Two gears 8 are sleeved on the outer wall of the hollow shaft 5, and the two gears 8 are respectively set in corresponding positions in the drive cavity. A rotating shaft 9 is rotatably installed on one side of the storage cavity. A turntable 10 and a fixed cylinder 11 are sleeved on the outer side of the rotating shaft 9. The fixed cylinder 11 is fixedly installed on the inner wall of the drive cavity on the side away from the turntable 10. Several tooth grooves that mesh with the gears 8 are opened on the outer side of the rotating shaft 9. A spring-loaded spring 12 is fitted inside the fixed cylinder 11, and the two ends of the spring-loaded spring 12 are fixedly connected to the fixed cylinder 11 and the rotating shaft 9, respectively. One end of the nozzle 2 3 passes through a through hole opened on the side wall of the box door 14. A cleaning component is fitted on the outside of the nozzle 2 3 on one side of the box door 14. The storage mechanism allows the nozzle 2 3 to be rolled up and stored in the storage box 4. The nozzle 2 3 can be pulled according to the use needs, thereby changing the length of the nozzle 2 3. This allows the length of the nozzle 2 3 to be adjusted according to actual needs, making it more applicable and preventing the nozzle 2 3 from scattering outside, thus making it more practical. In this example, the cleaning component includes a cleaning cylinder 15, which is fixedly installed on one side of the door 14. A mounting cylinder 16 is provided on one side of the cleaning cylinder 15, and one end of the mounting cylinder 16 is inserted into the cleaning cylinder 15. The mounting cylinder 16 is threadedly connected to the cleaning cylinder 15. Several support rods 17 are symmetrically arranged inside the mounting cylinder 16. A cleaning cotton 18 is provided inside the mounting cylinder 16, and the cleaning cotton 18 is movably sleeved on the outside of the support rods 17. The cleaning cotton 18 is sleeved on the outside of the nozzle 2 3. The cleaning component can wipe and clean the dust and other stains adhering to the surface of the nozzle 2 3.
[0022] In this example, the fixing component includes a fixing seat 19, which is fixedly installed on one end of a pipe clamp 13. A screw 23 is provided on one side of the left pipe clamp 13, passing through one end of both pipe clamps 13 and penetrating the fixing seat 19. A threaded nut 24 is fitted on the outer side of the end of the screw 23 away from the fixing seat 19, and the nut 24 is located on the left side of the pipe clamp 13. A plug 20 is provided on the top of the fixing seat 19, and the lower end of the plug 20 is inserted into the slot opened on the top of the screw 23. A pull handle 21 is connected to the upper end of the plug 20. A spring 22 is fitted on the outer side of the plug 20 between the pull handle 21 and the fixing seat 19. The fixing component allows for easy installation, fixing and disassembly of the pipe clamps 13, and the effect of fixing the two pipe clamps 13 can be adjusted as needed. In this example, the winding reel 7 is I-shaped, with several symmetrical insertion holes at one end. The storage box 4 has a bolt 25 threadedly connected to one end, with one end of the bolt 25 inserted into the corresponding insertion hole to limit and fix the winding reel 7 as needed. In this example, the diameter of the gear 8 is smaller than the diameter of the turntable 10, the slot is trapezoidal, and the lower end of the insertion rod 20 is adapted to the slot so that the screw 23 can directly push the insertion rod 20 upwards during installation, facilitating its installation.
[0023] The working principle of this utility model is as follows: During use, the nozzle 23 can be pulled out or pulled back as needed to adjust its length. Pulling the nozzle 23 causes the take-up reel 7 to rotate synchronously, which in turn drives the hollow shaft 5 to rotate synchronously. The hollow shaft 5 then drives the gear 8 to rotate synchronously, which, in conjunction with the gear-driven turntable 10, drives the rotating shaft 9 to rotate. This causes the rotating shaft 9 to twist the spring 12. When the pulling force on the nozzle 23 is gradually reduced, the rotating shaft 9 will return to its original position under the torque of the spring 12. This, in turn, drives the hollow shaft 5 to rotate the take-up reel 7 back to its original position, thus adjusting the rotation of the nozzle 23. During the winding process, after the nozzle 23 is pulled to a suitable length, it can be fixed by inserting the torsion bolt 25 into the corresponding hole on one end of the winding reel 7. This prevents the nozzle 23 from winding up if the pulling force on it is accidentally reduced. Simultaneously, the nozzle 23 is cleaned by the cleaning cotton 18 during winding. When the cleaning cotton 18 needs to be removed and replaced for cleaning, the mounting cylinder 16 can be twisted to separate it from the cleaning cylinder 15. Then the cleaning cotton 18 can be removed from the support rod 17 for replacement or cleaning. When it is necessary to disassemble the pipe clamp 13, the pull handle 21 can be pulled upward to drive the insertion rod 20, while stretching the spring 22, until the lower end of the insertion rod 20 moves out of the slot. Then the screw 23 can be pulled to one side to pull it out, thus completing the disassembly of the pipe clamp 13. During installation, one end of the screw 23 can be directly passed through the hole on one end of the two pipe clamps 13, and the screw 23 end can be inserted into the inside of the fixing base 19, so that the screw 23 end squeezes and pushes the inclined surface at the lower end of the insertion rod 20. The insertion rod 20 is moved upwards above the screw 23. When the lower end of the insertion rod 20 corresponds to the slot, the lower end of the insertion rod 20 can be inserted into the slot. Continue pushing the screw 23, and the bottom surface of the slot will press and push the insertion rod 20 upwards and out of the slot. Repeat this process to install and adjust the screw 23 to a suitable position, so that the nut 24 fits against one side wall of the pipe clamp 13. Then, the nut 24 can be turned as needed, so that the nut 24 drives the screw 23 to move to the left, thereby indirectly improving the connection and fixing effect of the two pipe clamps 13. It is convenient to use and more practical.
