[0019] 2. If it is necessary to cut or weld the pipe body, the pull rod can be pulled to drive the limit rod to move, and the limit rod moves and disengages from the limit groove. Then the positioning pin can be taken out, and the fixing plate loses its limit, and the fixing plate can be removed to avoid affecting the operation of the pipe body. When installing the fixing plate, the positioning pin is passed through the two positioning blocks and the positioning hole. One end of the positioning pin and the arc can push the limit rod to move. The positioning pin moves so that the limit rod is aligned with the limit groove. Under the action of the reset spring, the limit rod is engaged with the limit groove, and then the positioning pin is positioned, so that the fixing plate is fixed, which makes it convenient for the staff to disassemble the fixing plate and improves the convenience.

[0030] Working principle: Before using this natural gas pipeline isolation device, you need to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, an isolation component 2 is provided inside the pipeline body 1. When the natural gas pipeline is blocked, the installation rod 201 and the rubber ring 203 can be inserted into the pipeline body 1 so that the fixed plate 206 fits the opening of the pipeline body 1. Then, the U-shaped frame 207 can be pushed to move. The movement of the U-shaped frame 207 can push the sliding sleeve 210 to move through the fixed rod 209, and then the movable rod 211 can be pushed to rotate and slide on the movable sleeve 212. The movable sleeve 212 rotates on the support frame 213 for support, and then the movable block 216 can be driven to move toward the installation rod 201 through the movable rod 214, and the movable rod 214 slides on the connecting sleeve 217, so that the connecting rod 218 is rotated. After the connecting rod 218 rotates, it can push the movable plate 204 to move, and the movable plate 204 can squeeze the rubber ring 203, so that the rubber ring 203 is squeezed. The rubber ring 203 is squeezed and deformed, so that the outer side of the rubber ring 203 fits tightly against the inner wall of the pipe body 1, thereby blocking and isolating the pipe body 1. At the same time, the U-shaped frame 207 slides on the mounting rod 201, and because the lower side of the positioning rod 220 is arc-shaped, the U-shaped frame 207 drives the positioning rod 220 to move the positioning groove 223, which can lift the positioning rod 220. After isolating the pipe body 1, the positioning rod 220 is reset under the action of the telescopic spring 221 and engages with the other positioning groove 223, so that the U-shaped frame 207 can be automatically positioned after moving. Through the isolation component 2, when it is necessary to isolate the pipe, the pipe body 1 can be blocked and isolated, and the isolation through the rubber ring 203 will not be affected by sparks, so that subsequent work with fire can be carried out, and it is convenient for users to operate, thereby improving convenience and practicality.

[0031] When the pipe body 1 needs to be cut or welded, the pull rod 229 can be pulled to drive the limit rod 227 to move, and the limit rod 227 moves and disengages from the limit groove 230. Then the positioning pin 225 can be taken out, and the fixing plate 206 loses its limit, and the fixing plate 206 can be removed to avoid affecting the operation of the pipe body 1. When installing the fixing plate 206, the positioning pin 225 is passed through the two positioning blocks 224 and the positioning hole 226. One end of the positioning pin 225 and the arc can push the limit rod 227 to move. The positioning pin 225 moves to align the limit rod 227 with the limit groove 230. Under the action of the return spring 228, the limit rod 227 is engaged with the limit groove 230, and then the positioning pin 225 is positioned, so that the fixing plate 206 is fixed, which makes it convenient for the staff to disassemble the fixing plate 206 and improves convenience.
