A fixed pipe 5 is provided on one side of the valve body 1, and a fixing ring 6 is threadedly connected on both sides of the fixed pipe 5. An adjusting rod 7 is threadedly connected on the fixing ring 6. Rotating the adjusting rod 7 causes the limit ring 8 to move, which can drive the adjusting ring 10 and the fixed cover 11 to move, so that the fixed cover 11 contacts both sides of the valve body 1. At this time, the staff holds the fixed cover 11 and rotates the connecting plate 9 to make the fixed cover 11 closely contact both sides of the valve body 1. The adjusting rod 7 is rotated to connect A limiting ring 8 is provided, which is rotatably connected to a connecting plate 9 through a bearing. An adjusting ring 10 is fixedly connected to the connecting plate 9. The adjusting ring 10 is threadedly connected to a fixed cover 11. A connecting nut 12 is threadedly connected to one side of the fixed cover 11. A connecting tube 13 is threadedly connected to one side of the connecting nut 12. The fixed cover 11 has connecting ports at both ends, which can enable a piezoelectric gas pressure sensor 14 to be located in a detachable position. A piezoelectric gas pressure sensor 14 is fixedly connected to the fixed cover 11. The piezoelectric material is located in the connecting tube 13. When gas pressure is applied to the piezoelectric material, an electric charge and a voltage signal are generated, thereby determining the applied gas pressure after being measured and analyzed.

[0018] Among them, the breathing hole sealing plate 3 corresponds to the distance sensor 15, and the distance sensor 15 is fixedly connected in the fixed tube 5. By setting the distance sensor 15, the up and down movement of the movable sealing plate at the breathing hole can be observed.

[0019] Among them, the fixing ring 6 is fixedly connected to one side of the folding piece 19, the folding piece 19 is fixedly connected to one side of the limiting ring 8, and the limiting ring 8 is in contact with the fixed tube 5. By setting the folding piece 19, people can directly observe whether the folding piece 19 is expanded to determine whether there is leakage at the valve body 1 and the inlet and outlet pipe 4 of the valve body 1.

The gasket 18 is in contact with the bottom side of the valve body 1. By setting the spring rod 17 and the gasket 18, it can cooperate with the limit ring 8 and the connecting plate 9 to provide support for the valve body 1.

[0022] Working principle: Place the valve body 1 in the fixed tube 5. At this time, the gasket 18 is used to limit the valve body 1. Then, the fixed cover 11 is used to cover the inlet and outlet pipes 4. Then, the fixed ring 6 is connected to the fixed tube 5. At this time, the adjusting rod 7 is rotated to move the limit ring 8. At this time, the staff holds the fixed cover 11 and then rotates the handle 16 to rotate the connecting plate 9 until the fixed cover 11 contacts both ends of the valve body 1. Then, the connecting nut 12 is used to connect the fixed cover 11 and the connecting pipe 13. At this time, the movable sealing plate on the breathing hole can be observed through the distance sensor 15. At the same time, the personnel can observe whether the folding piece 19 is expanded to determine whether the valve body 1 is leaking, which improves the accuracy of gas pressure regulator fault monitoring and intuitively observes whether the gas pressure regulator is damaged.
