[0021] Further, the inside of positioning cylinder 8 is filled with lubricating oil, and a gap is left between the inner wall of positioning cylinder 8 and the outer wall of movable sleeve 9. The friction of movable sleeve 9 when sliding in the positioning cylinder 8 is reduced by the lubricating oil. When the outside is shaken, the movable sleeve 9 needs to extrude the lubricating oil on its moving side to flow along the gap between the movable sleeve 9 and the positioning cylinder 8, and then the movable sleeve 9 can move in the positioning cylinder 8. The outside shock is buffered, the anti-interference ability is improved, and the stability of pressure control when shaken is improved.

[0022] Further, the surface of the conductive wire 12 is coated with insulating paint, so that the adjacent turns of the spiral conductive wire 12 do not conduct electricity, and the current flows along the spiral. The surface of the conductive wire 12 away from the iron core 11 is not coated with insulating paint. The inner wall of the conductive ring 15 is in contact with the outer wall of the conductive wire 12. The conductive ring 15 is in contact with the conductive wire 12 to connect the upper end of the conductive wire 12.

[0023] Further, the outer wall of the regulating ring 14 is provided with a scale mark, and the size of the opening at the bottom of the sealing plate 5 is adjusted by adjusting the height of the regulating ring 14, so as to adjust the pressure.

[0024] Further, the outer wall of the regulating ring 14 is provided with a thread groove, and the inner wall of the protective cover 7 is provided with a matching thread ring. The regulating ring 14 moves longitudinally under the limitation of the thread groove and the thread ring by rotating the regulating ring 14.

[0025] Further, the inner wall of the protective cover 7 is provided with a vertical groove below the position of the push gap 13, and a conductive sheet is installed inside the vertical groove. The outer wall of the conductive ring 15 is provided with a conductive chuck, which extends into the vertical groove and contacts the conductive sheet. The conductive sheet is electrically connected to the inside of the junction box 16, and the bottom end of the conductive wire 12 is electrically connected to the inside of the junction box 16 through the wire. The current moves upward along the bottom end of the conductive wire 12 and moves to the inside of the conductive ring 15 through the position in contact with the conductive ring 15, so as to improve the spiral current flow trajectory of the conductive wire 12. A magnetic field is generated outside the conductive wire 12, and the generated magnetic field acts on the stressed iron block 10. The force of the magnetic field acting on the inside of the stressed iron block 10 is adjusted by adjusting the energized height of the conductive wire 12, so that the stressed iron block 10 is located at the center position of the magnetic field.

[0026] In use, the gas supply pipe is connected to the inlet connector 2, and the gas pipeline is connected to the outlet connector 4. The gas enters the inside of the inner flow cavity 3 through the inlet connector 2. When energized, the junction box 16 delivers current to the bottom end of the conductive wire 12 through the wire. The current flows upward along the spiral trajectory of the bottom end of the conductive wire 12, so as to form a magnetic field outside the conductive wire 12. Under the magnetic force of the formed magnetic field, the stressed iron block 10 is lifted upward, so that the stressed iron block 10 moves to the center position of the magnetic field formed by the seven conductive wires 12. The stressed iron block 10 drives the movable sleeve 9 to move upward along the inside of the positioning cylinder 8. The positioning cylinder 8 drives the connecting rod 6 to move upward, and the connecting rod 6 drives the sealing plate 5 to move upward, so as to release the sealing of the inside of the inner flow cavity 3. The gas can pass through the outlet connector 4 and be discharged to the right through the inner flow cavity 3. When it is needed to reduce the gas flow opening, the regulating ring 14 moves downward under the limitation of the thread by rotating the regulating ring 14. The regulating ring 14 drives the conductive ring 15 to move downward, and the conductive ring 15 moves downward to make the position in contact with the conductive wire 12 move downward, so as to shorten the length of the current flowing in the conductive wire 12. The center position of the magnetic field formed by the seven conductive wires 12 is offset downward, so that the stressed iron block 10 moves downward, thereby adjusting the height of the stressed iron block 10. The stressed iron block 10 moves downward to drive the connecting rod 6 to move downward through the movable sleeve 9, and the connecting rod 6 drives the sealing plate 5 to move downward, thereby reducing the size of the flow opening in the inside of the inner flow cavity 3 and adjusting the pressure of the gas discharged through the outlet connector 4.

[0027] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
