Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a supersonic high-pressure fluid nozzle. Background Art

[0002] Steam is also called "water vapor". According to pressure and temperature, various types of steam are classified into: saturated steam, superheated steam. The main uses of steam are heating / humidification; it can also generate power; it can be used as a machine drive, etc. When a liquid evaporates in a limited, enclosed space, the liquid molecules enter the space above through the liquid surface and become steam molecules. Because the steam molecules are in turbulent thermal motion, they collide with each other, the container wall and the liquid surface. When colliding with the liquid surface, some molecules are attracted by the liquid molecules and return to the liquid to become liquid molecules. At the beginning of evaporation, the number of molecules entering the space is greater than the number of molecules returning to the liquid. As evaporation continues, the density of the steam molecules in the space continues to increase, and thus the number of molecules returning to the liquid also increases. The steam engineering gas wave power conversion is a derivative of steam application.

[0003] At present, for low-quality public steam with a gauge pressure of <1 bar, a condenser is usually added to recover soft water, which not only wastes heat energy but also increases fixed investment. For high-pressure public steam, conventional technical measures such as throttling and spraying water mist to reduce superheat, reduce pressure and reduce temperature are often adopted, resulting in double waste of pressure energy and heat energy, which is inconsistent with my country's implementation of the "dual carbon" goal. The integrated technology of steam power exchange network is an effective solution, but it has encountered the research and development bottleneck of core power exchange equipment. The gas-wave steam power exchange technology utilizes the power exchange characteristics of the high pressure ratio of the wave rotor to achieve a larger pressure ratio. It has significant advantages in steam supercharging and superheat reduction applications, and the supercharging efficiency is much higher than that of the jet turbocharger. It can achieve two-phase supercharging characteristics and is better than conventional turbine equipment. In actual use, a jet booster requires a supersonic high-pressure fluid nozzle. The pipes on most jet boosters are connected to the supersonic high-pressure fluid nozzles through threads, and the replacement cycle of the supersonic high-pressure fluid nozzles is relatively long. When the supersonic high-pressure fluid nozzle is damaged, the supersonic high-pressure fluid nozzle and the pipe will be locked due to the characteristics of the threads, making it difficult to disassemble and replace the subsequent supersonic high-pressure fluid nozzles, affecting the subsequent use of the jet booster.

When the third magnet 14 moves inside the groove 4, the third magnet 14 can drive the movable plate 6 to move through the first magnet 7, so that the movable plate 6 moves inside the groove 4.

[0027] The working principle of the utility model is as follows: when the device is connected to the pipeline 9, the rotating rod 12 is rotated at this time, so that the rotating rod 12 drives the second magnet 13 and the third magnet 14 to move inside the groove 4, so that the second magnet 13 is away from the side of the first magnet 7, and the third magnet 14 reaches the side of the first magnet 7, and the third magnet 14 and the first magnet 7 repel each other, and the repulsive force between the third magnet 14 and the first magnet 7 is greater than the elastic force of the spring 11, so that the third magnet 14 can drive the first magnet 7 to move inside the groove 4, so that the first magnet 7 drives the moving plate 6 to move inside the groove 4, so that the moving plate 6 slides inside the groove 4, and the moving plate 6 slides on the outer wall of the fixed rod 5 at the same time, and the moving plate 6 squeezes the spring 11 at the same time, and the moving plate 6 can drive the locking block 8 to move, so that the locking block 8 slides inside the groove 4, and the locking block 8 can be connected The through groove 3 moves inside so that the engaging block 8 is completely moved out from the connecting groove 3.

The fluid will flush the block 19. When the block 19 has problems after long-term use, the threaded rod 18 can be rotated at this time, so that the threaded rod 18 can perform threaded movement with the mounting block 15 through the thread, so that the subsequent threaded rod 18 can rotate inside the mounting groove 16, and then the subsequent threaded rod 18 is separated from the stabilizing rod 17, so that the block 19 on the stabilizing rod 17 can be replaced, so as to prevent the block 19 from being damaged and causing the subsequent nozzle to be unusable as a whole.
