[0024] Embodiment 2;

[0025] like Figure 1-4As shown, it includes a metal sleeve 1, with flanges 2 at both ends. The outer wall of the metal sleeve 1 is provided with several alarm cylinders 4 distributed in a circumferential array. The alarm cylinders 4 are connected to the metal sleeve 1 via connecting columns 5. The alarm cylinder 4 is provided with a symmetrically arranged slide bar 1 6 on one side of the connecting column 5. One side of the slide bar 1 6 extends into the alarm cylinder 4 and connects to the alarm assembly. The side of the slide bar 1 6 away from the alarm cylinder 4 is provided with a slide bar 2 7. The side of the slide bar 2 7 away from the slide bar 1 6 extends into the metal sleeve 1 and connects to the circular arc fixing plate 8. One side of the circular arc fixing plate 8 is provided with an inner lining anti-corrosion pipe 9, which is welded to the circular arc fixing plate 8. A spring 10 is provided on the outside of the alarm cylinder 4 and on the outer wall of the slide bar 1 6. A thermal insulation layer 11 is provided between the metal sleeve 1 and the inner lining anti-corrosion pipe 9. Sliding rod 2 (7) is connected to alarm cylinder 4 via spring 10. Alarm cylinder 4 is provided with a first sliding hole that mates with sliding rod 1 (6), and metal sleeve 1 is provided with a second sliding hole that mates with sliding rod 2 (7). The alarm assembly includes a sliding pressure plate 12 that mates with the alarm cylinder 4. One side of sliding rod 1 (6) extends into the alarm cylinder 4 and connects to the sliding pressure plate 12. Pressure sensors 13 are symmetrically positioned on either side of the sliding pressure plate 12 and located on the inner wall of the alarm cylinder 4. A mounting plate 14 is provided on the outer wall of the metal sleeve 1. A PLC controller 15 is mounted on one side of the mounting plate 14. An alarm 16 is also mounted on the mounting plate 14 and located on the side of the PLC controller 15. Both the pressure sensor 13 and the alarm 16 are electrically connected to the PLC controller 15. A mounting groove 17 is provided on one side of the slide bar 7, and a non-destructive flaw detector 18 is provided in the mounting groove 17.

[0026] In actual application, when the lined anti-corrosion pipe 9 conveys liquid and is squeezed, the lined anti-corrosion pipe 9 squeezes the arc fixed plate 8, the arc fixed plate 8 squeezes the slide bar 2 7, the slide bar 2 7 squeezes the slide bar 1 6 and squeezes the spring 10 at the same time. When the lined anti-corrosion pipe 9 is squeezed too hard, the compression amount of the spring 10 increases. At this time, the slide bar 1 6 drives the sliding pressure plate 12 to squeeze a group of pressure sensors 13. The pressure sensor 13 transmits the squeezing signal to the PLC controller 15. The PLC controller 15 starts the alarm 16 to alarm and remind personnel. When the lined anti-corrosion pipe 9 is cooled and shrinks, the slide bar 2 7 is pulled by the arc fixed plate 8, and the slide bar 2 7 pulls the slide bar 1 6. At this time, the spring 10 begins to stretch and lengthen. When the lined anti-corrosion pipe 9 shrinks too much, the spring 1 0 The stretching length becomes larger. At this time, the slide bar 16 drives the sliding pressure plate 12 to squeeze another set of pressure sensors 13. The pressure sensor 13 transmits the squeezing signal to the PLC controller 15. The PLC controller 15 starts the alarm 16 to alarm and remind personnel. At the same time, the non-destructive flaw detector 18 monitors the weld between the arc fixing plate 8 and the inner lining anti-corrosion pipe 9 to prevent the weld from tearing. By setting the slide bar 1, the slide bar 2, the arc fixing plate and the spring, when the inner lining anti-corrosion pipe is squeezed, the pressure condition can be determined by the compression and stretching condition of the spring. By setting the alarm component, when the inner lining anti-corrosion pipe is squeezed too much, an alarm can be issued in time, which is convenient for personnel to check and prevent the inner lining anti-corrosion pipe from being broken and not replaced in time, causing waste.

[0027] To sum up, with the help of the above-mentioned technical scheme of the present invention, by setting the slide bar 1, the slide bar 2, the arc fixed plate and the spring, when the lining anti-corrosion pipe is squeezed, the pressure condition can be determined by the compression and stretching conditions of the spring. By setting the alarm component, when the lining anti-corrosion pipe is squeezed too much, an alarm can be issued in time, which is convenient for personnel to check and prevent the lining anti-corrosion pipe from being broken and not being replaced in time, causing waste.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
