A card plate 42 is movably inserted inside the card slot 41, and a sliding cavity 43 is provided inside the card plate 42. The inner wall of the sliding cavity 43 is slidably connected to a limit plate 44, and the top surface of the limit plate 44 is fixedly connected to a telescopic plate 45.

A connecting rod 47 is fixedly connected to the top of the outer wall on one side of the card plate 42, and a threaded ring 48 is fixedly connected to the outer wall on the side of the connecting rod 47 away from the card plate 42. The same bolt 49 is movably inserted in the two coaxial threaded rings 48, and a nut 410 is threadedly connected to the bottom of the outer surface of the bolt 49.

[0023] Further Figure 1 and Figure 3 As shown, it is worth explaining in detail that the detection mechanism 9 includes an installation box 91, the bottom surface of the installation box 91 is fixedly connected to the top surface of the threaded sleeve 8, and an electric push rod 92 is fixedly connected to the inner wall of the bottom surface of the installation box 91.

Then, use the same operation to install the lower arc plate 3 through the clamping plate 42 located below. When the size of the valve is larger, the relative distance between the two telescopic plates 45 on the same hinge 46 increases. When the size of the valve is smaller, the relative distance between the two telescopic plates 45 on the same hinge 46 decreases. After the upper arc plate 2 and the lower arc plate 3 are engaged with the outer surface of the valve through the connecting mechanism 4, insert the bolt 49 into the inside of the threaded ring 48, and tighten the nut 410 to fix the relative distance between the two telescopic plates 45, thereby realizing the installation of the detection device and effectively avoiding the problem that the detection device is not easy to adjust according to the size of the valve.

[0028] After the detection device is installed, turn on the electric push rod 92, which pushes the ultrasonic detection sensor 93 close to the valve body 1, and then turn on the drive motor 6. The drive motor 6 drives the reciprocating threaded rod 7 to rotate, and under the action of the thread, the threaded sleeve 8 drives the detection mechanism 9 to reciprocate. When the ultrasonic detection sensor 93 moves back and forth, it detects both sides of the valve body 1. When a leak occurs on one side of the valve body 1, the ultrasonic detection sensor 93 controls the alarm light 94 to light up, and at the same time controls the alarm 95 to sound. When the detection mechanism 9 moves to the normal side of the valve body 1, the alarm light 94 goes out and the alarm 95 stops working. The operation is simple and the detection effect is obvious. It effectively avoids the problem that the distance between the detector and the valve is far and easily affects the detection effect.
