[0026] Use principle and advantage: The specific space is separated by the first isolation plate 1 and the second isolation plate 10 in the nylon pipe 3, the connecting pipe 5 integrally formed between the two isolation plates becomes the core channel of fluid transmission, the external connecting pipe 4 is connected with the connecting pipe 5, and the interface of the fluid inlet and outlet flow channel components is formed, which provides the basic path for the flow of refrigerant or air in the automobile air conditioning system. The rectangular plate 17, spring 19, sliding rod 6 and piston 12 jointly constitute the flow regulating mechanism. When the fluid passes through the first flow port 7 in the first fixed pipe 16, the airflow will act on the spring 19 and the sliding rod 6 through the airflow channel 8. Under the action of the airflow pressure, the sliding rod 6 drives the piston 12 to slide in the connecting pipe 5. When the airflow pressure increases, the piston 12 compresses the spring 19 to slide away from the rectangular plate 17, so that the opening degree of the flow port 22 at the bottom of the sealing ring 9 in the connecting pipe 5 increases, and the fluid flow increases. Conversely, when the airflow pressure decreases, the spring 19 pushes the piston 12 to reset, the opening degree of the flow port 22 decreases, and the dynamic regulation of the fluid flow is realized. The vent hole 15 on the block 2 also plays an important role in this process. The existence of the vent hole 15 enables the airflow pressure in the first flow port 7 to be uniformly transmitted to the spring 19 and the sliding rod 6, ensuring the stable sliding of the piston 12 and the accuracy of the flow regulation. At the same time, the size and number of the vent hole 15 are carefully designed to ensure that enough airflow passes through to drive the piston 12 to move, and to avoid too fast airflow causing unstable pressure and affecting the flow regulation effect. The second fixed pipe 24, the flow port 22, the diffusion port 23 and the second flow port 11 constitute the fluid distribution and diffusion channel. When the piston 12 slides to change the opening degree of the flow port 22, the fluid enters the diffusion port 23 from the connecting pipe 5 through the flow port 22. The special design of the diffusion port 23 enables the fluid to be preliminarily diffused before entering the second fixed pipe 24, avoiding the impact on the subsequent pipeline and components caused by too fast flow speed or concentrated flow. The diffused fluid passes through the second flow port 11 in the second fixed pipe 24 and uniformly flows to the area below the second isolation plate 10, realizing the distribution and diffusion of the fluid. This design ensures the uniform distribution of the fluid in the flow channel components, helps to improve the refrigeration and heating effect of the automobile air conditioning system, makes the temperature in the vehicle more uniform, and improves the driving comfort. The connecting pipe 5 and the external connecting pipe 4 are tightly connected through the sealing ring 9 and the sealing convex ring 13. The sealing ring 9 is installed inside the end of the connecting pipe 5 away from the external connecting pipe 4, and the sealing convex ring 13 at one end of the external connecting pipe 4 is slidably installed in the inner circle of the connecting pipe 5. This structure design ensures the smooth connection of the external connecting pipe 4 and the connecting pipe 5, and effectively prevents fluid leakage. Whether it is refrigerant or air, the sealing effect of the sealing ring 9 and the sealing convex ring 13 is crucial when transmitting in a high-pressure environment. They can adapt to pressure changes under different working conditions, maintain good sealing performance, ensure that the fluid flows in the flow channel components according to the predetermined path, and avoid performance degradation or even failure of the air conditioning system caused by leakage.
