FIG. 25A shows the flange tightening training apparatus 80-1 according to the first embodiment. In this flange tightening training apparatus 80-1, the apparatus main body 222 is provided with a first seal application part 224-1 and a second seal application part 224-2, and each of the seal application parts 224-1 and 224-2 includes Are provided with flange joints having different diameters, gaskets 228-1 and 228-2 are sandwiched between flanges 226, and a plurality of bolts 230 and nuts 232 are provided. The trainee uses, for example, a torque wrench as a construction tool, and tightens the nut 232 sequentially to perform the sealing work.

Each bolt 230 is provided with a strain sensor 234 as shown in FIG. Each strain sensor 234 detects the axial force generated in the bolt 230 by the tightening torque τ of the nut 232.

This sensor output is taken into the PC 82 through the data logger 84 (FIG. 10). The PC 82 displays on the monitor 86 a polygonal graphic indicating the amount of axial force with the distance from the center of the axial force being tightened in real time.

The training result is stored in the construction training information table 112 in association with the trainee.

FIG. 26A shows a creep relaxation training apparatus 80-2 according to the second embodiment. In FIG. 26A, the same reference numerals are given to the common parts with FIG. In this creep mitigation training apparatus 80-2, heaters 236-1 and 236-2 are installed in the respective piping parts 235 sandwiching the seal application part 224-3.

Thereby, it is possible to recognize the decrease in surface pressure, and to allow the trainee to learn the effective timing of initial tightening force and increasing tightening.

FIG. 27 shows a sealing practice device 80-3 according to the third embodiment. In FIG. 27, the same reference numerals are given to the portions common to FIG. In this sealing performance training apparatus 80-3, the apparatus main body part 222 is provided with a first seal application part 224-1 and a second seal application part 224-2, and a gasket 228 is sandwiched between the flanges 226, A plurality of bolts 230 and nuts 232 are provided.

A pressure sensor 239 for detecting the pressure in the apparatus main body 222 is provided along with the pressurizing device 238 for pressurizing the inside of the apparatus main body 222 to the closing flange 226 on the top side of the apparatus main body 222. The pressure sensor 239 detects a pressure change due to the seal deterioration of the seal application parts 224-1 and 242-2.

The sealing performance of the seal construction parts 224-1 and 224-2 is affected by the flange 226, the gasket 228, and the bolt 230. The flange 226 affects the surface scratches, surface roughness, corrosion, the gasket 228 surface scratches, adhesion of foreign matters such as dust, rust in the bolt state, and the lubricant affects the sealing performance of the gasket 228.

With this sealing performance training apparatus 80-3, troubles due to the states of the flange 226, the gasket 228, or the bolt 230 can be reproduced, and the trainee can learn the leak check technique.

FIG. 28 shows an on-site simulated tightening training apparatus 80-4 according to the fourth embodiment. In FIG. 28, the same reference numerals are given to the portions common to FIG. This on-site simulated tightening training apparatus 80-4 simulates a seal construction site under poor conditions in terms of seal construction work, and allows the trainee to master the seal construction.

In the seal construction site, seal construction is forced under poor conditions such as high places, narrow places, and obstacles. In addition to high places, for example, piping, racks, structures, equipment, etc. are complicated, and there are narrow spaces. As shown in FIG. 28A, a plurality of pipes 240-1, 240-2, and 240-3 are adjacent to each other, and flange joints 242-1, 242-2, and 242-3 that are seal construction portions are adjacent to each other. There is a case. As shown in FIG. 28B, when a plurality of pipes 240-4 and 240-5 intersect adjacent to each other, and flange joints 242-4 and 242-5, which are seal construction parts, are adjacent to the intersection. There is. Further, as shown in FIG. 28C, the pipe 240-6 may be disposed adjacent to the structure 244, and the flange joint 242-6 may be adjacent to the structure 244. Assuming such on-site conditions of seal construction, the on-site simulated tightening training device 80-4 freely reproduces the assumed seal construction site, such as high places, narrow places, and obstacles, under poor conditions that impede workability. Let the trainees learn how to install the seal.

FIG. 29 shows a pipe alignment training device 80-5 according to the fifth embodiment. In FIG. 29, the same reference numerals are given to the portions common to FIG. At the site of the seal construction, as shown in FIG. 29A, when the intervals between the flanges 226 of the pipes 240-11 and 240-12 to be connected are wide, as shown in FIG. 29B, the pipes 240-11, When the interval between the flanges 226 of 240-12 is narrow, as shown in FIG. 29C, the parallelism cannot be obtained due to the inclination between the flanges 226 of the pipes 240-11 and 240-12. As shown in 29D, a case is encountered in which there is misalignment between the flanges 226 of the pipes 240-11 and 240-12. In such a situation, an appropriate tightening force cannot be transmitted to the gasket 228 even when tightening with a uniform tightening force. In this pipe alignment training apparatus 80-5, gaps, inclinations, misalignments, etc. are freely set to reproduce actual misalignment, and the trainer is trained in seal construction to solve the misalignment. The situation of tightening (surface pressure) by trainees is evaluated for these situations.

¡The heat exchanger has a more complicated structure than a general flange for pipe connection, and seal construction is required to understand the structure. Since the fixed tube plate is clamped with two gaskets sandwiched between the flanges, it is easy to cause one-side tightening. A large-diameter flange has a large number of bolts, and a decrease in tightening force between adjacent bolts during tightening due to elastic interaction between the flanges cannot be ignored. Further, with respect to the partition plate, if the tube flange / shell flange is misaligned, the partition plate does not enter the groove, so that problems such as climbing occur. Such special structure, optimum tightening force, selection of appropriate construction tool, and tightening procedure are required.

In this heat exchanger training device, the heat exchanger is disassembled, and trainees are trained on the actual machine, such as bolt tightening of the fixed tube plate and centering of the tube flange and shell flange, which are necessary for seal construction.

Compressive fracture training device allows trainees to learn about compression fracture of gaskets due to overtightening. Compressive failure reproduces the situation where compression failure is likely to occur for the type of gasket, paste application, small-diameter flange, etc., and learns the causes of leakage and its prevention. For example, expanded graphite sheet gaskets have a lower compressive fracture surface pressure than other gaskets, while sealing improves the paste performance, but compressive fracture tends to occur, and small-diameter flanges have a smaller gasket area relative to the number of bolts. In addition, since the surface pressure is likely to be high, compression failure is likely to occur.

Therefore, in this compressive fracture training device, the trainee can learn the relationship between the type of gasket and the presence or absence of paste and crack deformation and cracks that are the cause of compressive fracture, regarding the compressive fracture that is a cause of leakage.

As other examples, a torque sensation training device, a ground packing training device for an actual rotary pump, and a ground packing training device for an actual valve are used. In the torque sensation training apparatus, the trainee can experience the transition of tightening torque and axial force for a plurality of bolts and nuts having different tightening conditions.
