[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0023] Please refer to Figs. 1-3 The present invention provides a flange seal failure simulation device, including a water tank 1, a water pump 2 and a connecting pipe 5. One end of the water pump 2 is connected to the water tank 1 and the other end is connected to the connecting pipe 5. The connecting pipe 5 is used to be wrapped around the flange joint.
[0024] Since the water tank 1 and the water pump 2 are relatively heavy, they can be placed on a movable trolley for free movement. The connecting pipe 5 can be a PVC plastic hose. The first and second water outlets are both set away from the flange connection to simulate flange leakage.
[0025] A plug 6 is provided at the end of the connecting pipe 5 away from the water pump 2. Several first nozzles 7 and second nozzles 8 are provided in the middle of the connecting pipe 5. The first nozzles 7 and second nozzles 8 are used to discharge the liquid pumped by the water pump 2. The first nozzles 7 are used for single-point seal failure simulation, and the second nozzles 8 are used for seal failure simulation of several lengths.
[0026] The structure of this invention mainly includes a water tank 1, a water pump 2, and a connecting pipe 5. Several first nozzles 7 and second nozzles 8 are arranged in the middle of the connecting pipe 5. Both the first nozzles 7 and second nozzles 8 are used to discharge the liquid pumped by the water pump 2. The first nozzles 7 are used for simulating single-point seal failure, and the second nozzles 8 are used for simulating seal failure over a length of time. Through this structure, by starting the water pump 2 and controlling it with a pressure valve, and by using appropriate nozzle combinations, simulations of different stages of flange water penetration (small dripping, single-point water penetration, and section water penetration) can be achieved, thereby quickly obtaining effective training data. This allows for low-cost simulation of flange seal failure without damaging the flange seal, facilitating image data acquisition and saving experimental costs.
[0027] It should be noted that one end of the plug 6 needs to be fixed during use. This can be done by using a heavy object, manual fixation, or a special structure, as long as the plug 6 can be temporarily fixed to prevent the connecting pipe 5 from detaching from the flange when the water pump 2 is pressurized.
[0028] In one exemplary embodiment of this utility model, the first nozzle 7 has a first water outlet in the middle, and its two ends are connected to the connecting pipe 5. The second nozzle 8 has a second water outlet in the middle, and its two ends are connected to the connecting pipe 5. The length of the first water outlet is smaller than that of the second water outlet.
[0029] Specifically, the first outlet is circular, and the second outlet is rectangular.
[0030] An exemplary embodiment of this utility model further includes a pressure gauge 3 and a control valve 4. Both the pressure gauge 3 and the control valve 4 are located at the outlet of the water pump 2. The pressure gauge 3 is used to detect the pressure of the connecting pipe 5 and to know the current liquid pressure in the simulated flange. The control valve 4 is used to control the pressure in the connecting pipe 5.
[0031] In addition, since the liquid coming out of the first nozzle 7 and the second nozzle 8 may be under considerable pressure, making it difficult for staff to observe closely, this solution also includes a display device and a camera module to facilitate observation of the simulated leak.
[0032] The camera module is electrically or communicatively connected to the display device. The camera module is used to capture the dynamics of the simulated flange failure, and the display device is used to display the images captured by the camera module. The display device can be placed at a distance so that it can promptly detect the simulated leak without being splashed by liquid.
[0033] Specifically, the camera module includes a housing 12, a camera 14, and a connecting device. The camera 14 is disposed inside the housing 12, and the connecting device is connected to the housing 12 to house the housing 12 within a flange.
[0034] The connecting device includes a clamping device and a support rod 13. One side of the clamping device is connected to the support rod 13. The outer shell 12 is disposed on the support rod 13. The clamping device is used to fix the support rod 13 to the flange.
[0035] The clamping device includes a spring 10, a fixing plate 9, and a connecting plate 11. Two sets of springs 10 and fixing plates 9 are symmetrically arranged inside the fixing plate 9. One end of the spring 10 is connected to the connecting plate 11, and the other end is connected to the fixing plate 9. The fixing plate 9 is connected to the support rod 13.
[0036] When in use, the connecting plate 11 is brought into contact with the flange edge and the spring 10 is compressed, which can fix the fixing plate 9 on the flange. The outer shell 12 is made of transparent material and a mobile power supply can be installed inside.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
