[0018] The technical solution of the utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0019] like Figure 1 to Figure 2 As shown, the utility model provides a pipeline blockage simulation training device, which includes a support frame 1 and a pipeline system 2; the pipeline system 2 is fixedly installed on the support frame 1 through a clamp 3;

[0020] The piping system 2 includes a water inlet 201, a pressure gauge 202, a relief valve 203, a water inlet main pipe 204, a water inlet branch pipe 205, a solenoid valve 206, a leakage pipe 207, a water outlet branch pipe 208, a water outlet main pipe 209, a water outlet 210 and an electronic control device (not shown); the water inlet 201 is connected to a water inlet main pipe 204, and the water inlet main pipe 204 is connected to at least two water inlet branches 205 to serve as a branch; the pressure gauge 202 is installed on the water inlet main pipe 204; the relief valve 203 is installed on the water inlet main pipe 204 or one of the water inlet branches 205; each A solenoid valve 206 is fixedly connected to each water inlet branch pipe 205, and a leakage pipe 207 is fixedly connected behind the solenoid valve 206. The leakage pipe 207 is provided with cracks or holes, and the diameters of the leakage pipes 207 on different branches are different; a water outlet branch pipe 208 is fixedly connected behind each leakage pipe 207, and a water outlet main pipe 209 is connected behind the water outlet branch pipes 208 of all branches, and the water outlet main pipe 209 is connected to a water outlet 210; the electronic control device is connected to the solenoid valves 206 on all branches, and is used to independently control the solenoid valve 206 on each branch.

[0021] A leakage pipe 207 on each branch corresponds to a leakage situation of a pipe diameter. When the equipment is working, the water outlet 210 is closed, or it can also be connected to other equipment for joint use. Liquid is input into the pipeline system 2 through the water inlet 201. At this time, all solenoid valves 206 are in a closed state. The pressure gauge 202 can monitor the pressure of the pipeline system in real time. When it exceeds the safe pressure range and reaches the threshold of the overflow valve 203, the overflow valve 203 begins to overflow, thereby maintaining the system pressure within a safe range. Each solenoid valve 206 in the pipeline system 2 controls a branch, thereby controlling various types of leakage scenarios such as different pipe diameters and different positions. The opening of the solenoid valve 206 is controlled by the electronic control device, thereby simulating different leakage scenarios, such as crack leakage, loose interface, hole leakage, flange 213 leakage, etc.

[0022] Furthermore, the pipeline system 2 is also provided with an internal plugging pipe 211, which is connected to one of the water inlet branches 205, and an electromagnetic valve 206 is connected between the internal plugging pipe 211 and the water outlet end of the corresponding water inlet branch 205; and the water outlet end of the internal plugging pipe 211 is suspended.

[0023] The leakage pipe 207 simulates the leakage of the pipe wall, and the training can be carried out to block the outer wall of the leakage pipe 207. The inner plugging pipe 211 simulates the leakage of the pipeline rupture, and the training can be carried out to block the cross section of the inner plugging pipe 211. The electromagnetic valve 206 in front of the inner plugging pipe 211 is opened, and the training can be carried out.

[0024] Specifically, the inner plugging pipe 211 is arranged below the water inlet main pipe 204. In this way, when the training is finished, the electromagnetic valve 206 in front of the inner plugging pipe 211 can be opened to drain the accumulated water in the pipeline system 2 by utilizing the principle that water flows downward.

[0025] Preferably, the pipeline system 2 is further provided with a manual gate valve 212, which is connected to one of the water inlet branches, and a solenoid valve 206 is connected between the manual gate valve 212 and the outlet end of the corresponding water inlet branch pipe 205. Thus, leakage of the manual gate valve 212 can be simulated, adding a simulation scenario.

[0026] As an improvement, the water inlet and outlet ends of the solenoid valve 206 and the water inlet and outlet ends of the leakage pipe 207 are both provided with connection flanges 213, and the solenoid valve 206 and the leakage pipe 207 are fixedly connected via the connection flanges 213. These flange 213 interfaces can simulate the scene of flange 213 leakage and facilitate subsequent disassembly and replacement.

[0027] As an improvement, a one-way valve 214 for one-way flow to the water outlet 210 is fixedly connected to the leakage pipe 207. Each branch can prevent liquid from flowing back and damaging the parts of the pipeline system 2 by arranging a one-way valve.

[0028] Since pipeline leakage is not necessarily a liquid pipe leakage, it may be a gas pipe leakage. In order to enable the device to simulate a gas pipe leakage scenario, preferably, the water inlet main pipe 204 or the water inlet branch pipe 205 is provided with an air inlet interface for introducing gas into the pipeline system 2.

[0029] As an improvement, the bottom of the support frame 1 is provided with universal wheels and adjustment feet, wherein the adjustment feet are threadedly connected to the support frame 1. The universal wheels can drive the equipment to move at will, making it convenient to transfer the training venue. Before using the equipment, first operate the adjustment feet to fix the equipment.

[0030] The utility model provides a pipeline blockage simulation training device, which can simulate leakage scenarios of various leakage types in different positions and different pipe diameters, and can train the training personnel's ability to block leaks in a more comprehensive and comprehensive manner. Each pipeline and valve is spliced ​​by a flange 213, which is convenient for disassembly and replacement of damaged parts. At the same time, new pipelines can be expanded on the original pipeline system 2 according to training needs, thereby simulating more leakage scenarios. And the solenoid valve 206 is used to control each different type of leakage scenario, which improves the efficiency and convenience of training compared to the original manual valve solution. The setting of the one-way valve 214 can also prevent equipment damage and increase the service life of the equipment.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
