[0032] Working principle:

[0033] Gas enters through the external interface 3 of the pressure regulator, which is provided with a tightening thread groove 4 to facilitate firm connection with the gas source pipeline and ensure that the gas enters the pressure regulator without leakage. The gas enters the gas inlet pipeline 11 from the external interface 3, and then enters the interior of the pressure regulator through the air pipe 15 movably connected to the rotating plate 14. The rotating plate 14 is supported by the rotating piece 13 fixed to the side of the fixed plate 12 and can be fine-tuned in angle with the rotation of the rotating knob 2, thereby indirectly affecting the connection state between the air pipe 15 and the diaphragm 10, providing the possibility for preliminary gas pressure regulation. The diaphragm 10, as the core component of pressure sensing and regulation, is connected to the first spring 8 in the rotating cover 6 on the other side. When the rotating knob 2 is operated, the rotating cover 6 moves up and down through the interaction of the threaded strip 7 and the threaded sleeve 5, thereby compressing or releasing the first spring 8. The compression degree of the first spring 8 directly affects the deformation amount of the diaphragm 10, thereby changing the pressure of the gas after passing through the diaphragm 10. By precisely adjusting the rotating knob 2, the user can achieve fine control of the output gas pressure. The deformation of the diaphragm 10 is also affected by the gas pressure in the gas inlet pipeline 11, forming a dynamic balance state, ensuring that stable gas pressure can be output under different input pressures. The sealing block 20 at the lower end of the rotating knob 2 forms a tight fit with the sealing groove 18 on the housing 1, and the sealing strip 19 provides additional sealing effect between the sealing groove 18 and the sealing block 20, effectively preventing gas leakage and ensuring the sealing and safety of the pressure regulator. The second spring 17 in the fixed column 22 and the fixed groove 24 provides additional buffering and stability for the movement of the rotating cover 6, ensuring that the rotating cover 6 can move smoothly and accurately to the target position during adjustment. The limit plate 23 and the limit groove 21 limit the movement range of the rotating knob 2 and the rotating cover 6, preventing damage or failure caused by excessive adjustment, further ensuring the regulation accuracy and stability of the pressure regulator.
