[0022] like Figs. 1-3 As shown, a bellows leakage diagnostic device for a regulating valve includes an I-shaped base 1. The upper plate of the I-shaped base 1 has symmetrically symmetrically formed strip-shaped notches 2, which facilitate the installation and subsequent operation of the lower components. Two liquid storage cylinders 3 are symmetrically installed on the I-shaped base 1 above the strip-shaped notches 2. A connecting hose 4 is fixedly installed at one end of each liquid storage cylinder 3. One end of the connecting hose 4 is connected to the liquid storage cylinder 3, and the other end of the connecting hose 4 is fixedly installed with a flange plate. The connecting hose 4 and flange plate facilitate quick and easy connection to both sides of the regulating valve, thereby improving operational efficiency during the detection process.

[0023] The bottom of each liquid storage cylinder 3 is provided with a liquid recovery mechanism, which comprises a recovery cylinder 11 fixedly installed on the bottom end side wall of the liquid storage cylinder 3 and communicating with the liquid storage cylinder 3, an electric hydraulic rod 12 fixedly installed on the bottom end side wall of the recovery cylinder 11, and a push piston 13 fixedly installed at one end of the electric hydraulic rod 12 and slidingly arranged in the recovery cylinder 11. In this way, the electric hydraulic rod 12 pushes the liquid in the recovery cylinder 11 into the liquid storage cylinder 3 and the valve body of the regulating valve through the push piston 13, and then the liquid fills the space between the liquid storage cylinder 3 and the valve body. The control panel 5 is fixedly installed on the side wall of the I-shaped base 1 and electrically connected with the electric hydraulic rod 12, so that the control panel 5 can conveniently control the electrical elements in the device.

[0024] One of the liquid storage cylinders 3 is provided with a pressure applying mechanism, which comprises a piston pressing plate 6 slidingly arranged in the liquid storage cylinder 3 and provided with a containing groove on the side wall, and a limiting box 7 symmetrically installed on the side wall of the liquid storage cylinder 3 and provided with a weight block 8. The weight block 8 can apply pressure change to the piston pressing plate 6, so as to detect the valve body of the regulating valve.

[0025] The other liquid storage cylinder 3 is provided with a pressure sensing mechanism, which comprises a sealing plate 9 fixedly installed in the liquid storage cylinder 3 and provided with a pressure sensing instrument 10 fixedly installed thereon, and a moving piston 14 fixedly installed on the detection head of the pressure sensing instrument 10 and slidingly arranged in the liquid storage cylinder 3. When the pressure change of the pressure sensing instrument 10 does not match the gravity of the weight block 8, it indicates that the corrugated pipe regulating valve is damaged and leaks, so that the safety of the corrugated pipe regulating valve can be quickly tested, and the detection efficiency of the regulating valve is effectively improved.

[0026] In summary, when detecting the corrugated pipe regulating valve, the two connecting hoses 4 and the flange edges of the two liquid storage cylinders 3 are fixedly installed at the two end ports of the regulating valve, and then the electric hydraulic rod 12 is started by the control panel 5, so that the electric hydraulic rod 12 pushes the liquid in the recovery cylinder 11 into the liquid storage cylinder 3 and the valve body of the regulating valve through the push piston 13, and then the liquid fills the space between the liquid storage cylinder 3 and the valve body. Then the weight block 8 is continuously put into the containing groove of the piston pressing plate 6, and then the pressure is conducted to the moving piston 14 through the liquid, and then the moving piston 14 conducts the pressure to the pressure sensing instrument 10. The pressure sensing instrument 10 detects the change of the pressure. First, a weight block 8 is placed to test the frictional resistance that needs to be offset in the pressure conduction process, and then another weight block 8 is placed. When the pressure change of the pressure sensing instrument 10 does not match the gravity of the weight block 8, it indicates that the corrugated pipe regulating valve is damaged and leaks.
