When the No. 1 locking frame 8 and the No. 2 locking frame 9 are tightly attached, the No. 2 card plate 11 can be rotated toward the No. 1 card plate 10, and the right-angled trapezoidal block on the No. 1 card plate 10 can be tightly attached to the right-angled trapezoidal block on the No. 2 card plate 11. At the same time, the No. 1 card plate 10 will be firmly adsorbed with the No. 2 card plate 11, so This can lock the No. 1 locking frame 8 and the No. 2 locking frame 9 together to avoid looseness, and in this process, the long protrusions in the inner rectangular grooves of the No. 1 locking frame 8 and the No. 2 locking frame 9 will be embedded in the long grooves on the mounting plate 7, ensuring that the No. 1 locking frame 8 and the No. 2 locking frame 9 are fixed to the front and rear sides of the lower shell 1 and the upper shell 2, and the warning ball 6 can be pressed down to the bottom in advance during assembly. After the device is assembled, the cavities on the inner sides of the lower shell 1 and the upper shell 2 will be in a closed state. When a leak occurs at the flange joint position of the chemical pipeline, the air pressure in the cavities on the inner sides of the lower shell 1 and the upper shell 2 will increase, thereby pushing the piston 5 to slide upward in the support cylinder 4, and the warning ball 6 will also move up, which is convenient for workers to discover and repair in time, and the liquid flowing out through the flange joint position will flow into the liquid collecting bottle 3 for collection.
