When the processing sequence of the skill determination is shifted, it is determined whether it is a new person or general person (S501). This processing may be performed by the input information of the trainer. The term "new person" refers to a person who is responsible for the construction of a seal, but has experience equivalent to that of a non-executive or non-manager. "General" means a general person who wishes to receive enlightenment on the construction of a seal, such as a student.

If it is new or general (YES in S501), the skill 1 is selected (S502) and the process returns to S404 of the seal construction training program (Fig. 21).

If it is not new or general (NO in S501), the process shifts to the skill information input (S503). As skill information input, information necessary for skill determination is input, and skill determination is performed based on this information input (S504). By skill determination, skill 2, skill 3, ... Skill N (S505). In this example, the trainee is divided into N stages from the lowest skill 1 to the highest skill N, and the process returns to S404 of the seal construction training program (Fig. 21). This skill level can be either 2, 3, 4, or 5.

In this flange tightening training apparatus 80-1, a first seal installation portion 224-1 and a second seal installation portion 224-2 are provided in the apparatus main body portion 222, and each seal installation portion 224 -1 and 224-2 are provided with flange joints having different diameters and gaskets 228-1 and 228-2 are inserted between the flanges 226 and a plurality of bolts 230 and nuts 232 Respectively. The trainee uses a torque wrench, for example, as a construction tool, tightens the nut 232 in sequence, and performs seal construction.

Each bolt 230 is provided with a strain sensor 234 as shown in Fig. An axial force generated in the bolt 230 is detected by the tightening torque? Of the nut 232 at each of the strain sensors 234.

This sensor output is introduced to the PC 82 via the data logger 84 (Fig. 10). The PC 82 displays on the monitor 86 a polygonal graphic representing the magnitude of the axial force from the center in real time in the axial direction during tightening.

The results of the training are stored in the construction training information table 112 in association with the trainers.

Example 2

Pressure changes due to seal deterioration of the seal application portions 224-1 and 224-2 are detected in the pressure sensor 239. [

The sealability of the seal application portions 224-1 and 224-2 is influenced by the flange 226, the gasket 228, and the bolt 230. In the flange 226, scratches on the surface, surface roughness, corrosion, scratches on the surface of the gasket 228, adhesion of foreign matter such as sand dust, and rust and lubricant in the bolt state influence the sealability of the gasket 228.

Example 4

Fig. 28 shows a field simulated tightness training exercise apparatus 80-4 according to the fourth embodiment. In Fig. 28, the same parts as those in Fig. 25 are denoted by the same reference numerals. In this field simulated tightening and practicing apparatus (80-4), the seal construction work under the poor condition is simulated in the seal construction work, and the seal construction is learned to the trainee.

At the seal construction site, seal construction under severe conditions such as high altitude, narrow and obstacles is forced. In addition to complaints, for example, piping, racks, structures, appliances, etc. are complicated, and there is a narrow space. As shown in Fig. 28A, the plurality of pipes 240-1, 240-2, and 240-3 are adjacent to each other, and the flange joints 242-1, 242-2, and 242-3, which are seal- . 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 sealing portions, are adjacent to the intersections . 28 (C), the pipe 240-6 is disposed adjacent to the structure 244, and the flange joint 242-6 is adjacent to the structure 244. As shown in Fig. Under the assumption of such a situation of the seal construction, the field simulated tightening training apparatus (80-4) freely reproduces the assumed seal construction site such as the high, narrow and obstacle, and the seal construction under the bad condition To the trainee.

Example 5

Fig. 29 shows a piping alignment exercising apparatus 80-5 related to the fifth embodiment. In Fig. 29, the same reference numerals are given to common parts as those in Fig. 29A, when the interval between the flanges 226 of the pipes 240-11 and 240-12 to be connected is wide, as shown in Fig. 29B, When the interval between the flanges 226 of the pipes 240-11 and 240-12 is narrow, as shown in Fig. 29C, There is a gap between the flanges 226 of the pipes 240-11 and 240-12 as shown in D of FIG. 29, for example. In such a situation, even when tightened with a uniform tightening force, the tightening force can not be transmitted to the gasket 228 properly. In this piping alignment exercising apparatus 80-5, clearance, inclination, core deviation, and the like are freely set so that actual misalignment is reproduced, and the sealer practicing the seal installation for solving the misalignment is practiced. For these situations, the situation of tightness by the trainee is evaluated.

Example 6

It is required that the heat exchanger is complicated in structure compared to a general flange for pipe connection, and that the seal installation is carried out from the understanding of its structure. In the fixed plate, since two gaskets are sandwiched between the flanges, tightening bias is apt to occur. In the flange of the large diameter, the number of bolts is large, and the deterioration of tightening force between the adjacent bolts during tightening due to the elastic interaction between the flanges can not be ignored. In addition, with respect to the partitioning plate, if a core discrepancy occurs in the tube flange / shell flange, there arises a problem that the partitioning plate does not enter the groove and sinks. Such a special structure, optimum clamping force, proper construction tool selection, tightening sequence are required.

In this heat exchanger training apparatus, the heat exchanger is disassembled, and bolt tightening of the fixed plate, necessary for aligning the tube flange and shell flange at the time of seal construction is practiced to the trainee.

Example 7

In the compression fracture training device, the trainee learns compressive failure of the gasket due to excessive tightening. Compressive failure reproduces a situation in which compression fracture tends to occur with respect to kinds of gaskets, paste application, small diameter flange, etc., and learns factors of leakage and its prevention. For example, the expanded graphite sheet gasket has a lower compressive fracture surface pressure than other gasket, and the sealability is improved in paste application, while compression fracture tends to occur. In a small diameter flange, the gasket area with respect to the number of bolts is small , And that the surface pressure is liable to be increased, so that compression fracture tends to occur.

Thus, in the compression fracture training apparatus, the trainee can learn the kind of the gasket, the presence or absence of the paste, and the relationship of the crack deformation and the crack, which are the factors of compression fracture,
