In the process of the seal construction training, it is determined whether or not to train as a wishly confirmation for the trainer based on the training screen of the PC (S401). When the training is shifted (yes in S401), it is confirmed whether the importance of the seal selection is recognized (S402). If the importance of seal selection is not recognized ("NO" of S402), seal selection training is performed (S403). The training selected for the seal is to be repeated for lecture. In this way, the purpose of confirming the knowledge of the seal selection is to identify the seal used for the actual seal construction, and to train the seal construction on the premise of the identification, thereby improving the training effect. If the training for seal selection (S403) is over, then S402 is returned.

If the importance of the seal selection has been recognized ("yes" at S402), a trainer skill determination is made (S404). This skill determination is performed by the skill determination processing (fig. 22).

After the skill determination, course selection for training is performed (S405). The course selection is performed by the course selection process (fig. 23).

After course selection, the willingness of training is confirmed (S406), and training of the lecture program is first performed by starting training (yes in S406) (S407). The lecture program is executed by the lecture system 34-1 and ends according to a predetermined subject and time. In this case, depending on the evaluation, a relearning is required.

If the lecture program ends (yes in S408), the routine proceeds to a practice program (S409). The practice procedure is performed by the practice system 34-2, selecting devices and performing the necessary practices according to the subject matter and time specified. In this case, evaluation based on input information based on sensor output or training is performed, and re-learning is required depending on the evaluation.

If the practice program ends (yes in S410), the training program for the sealing work ends, and the completion is presented (S411).

< Process for skill determination >

Fig. 22 shows a processing procedure of skill determination. When the process goes to the skill determination process, a determination is made as to whether it is a new person or an ordinary person (S501). The processing is performed according to the input information of the trainer. "New person" means a person involved in the sealing work, but the "New person" has no experience with the sealing work at all, or is equivalent to a person who is inexperienced. "general" can be assumed to be an ordinary person who wants to receive training for sealing work, such as a student.

If it is a new person or an ordinary person (yes in S501), skill 1 is selected (S502), and the routine returns to S404 of the seal construction training program (fig. 21).

If it is not a new person or an ordinary person (NO in S501), the process proceeds to skill information input (S503). In the skill information input, information necessary for skill determination is input, and skill determination is performed based on the information input (S504). By this skill determination, any one of skill 2, skill 3, … … skill N is assigned from among a plurality of skills (S505). In this example, the trainer is classified into N classes from the lowest skill 1 to the highest skill N, and returns to S404 of the seal construction training program (fig. 21). The skill level may be any of level 2, level 3, level 4, level 5, etc.

< course determination Process >

Fig. 23 shows a procedure of course selection. When the process proceeds to the course selection process, a determination is made as to whether it is a new person or an ordinary person (S601). As described above, this process may be performed based on the input information from the trainer.

If it is a new person or an ordinary person (yes in S601), a basic course is selected (S602), and the routine returns to S405 of the seal construction training program (fig. 21).

If it is not a new person or an ordinary person (NO in S601), it is determined whether or not it is a custom course (S603). If it is not a custom course (NO in S603), a professional judgment of the trainer is made (S604). Any one of the superior course 1, the superior course 2 … …, and the superior course N is selected from the plurality of superior courses according to the occupation determination (S605).

If it is a custom course (yes in S603), professional judgment of the trainer is made (S606). Based on the occupation determination, any one of custom course 1, custom course 2, … …, and custom course N is selected from the plurality of custom courses (S607).

(2) With the seal construction instruction from the PC 24 as a trigger, the constructor 6 receives the seal construction training at the support center 8, and performs the training for selecting the seal when the support center 8 performs the seal construction.

(3) The customer 4 instructs the constructor 6 to purchase the seal selected in the support centre 8. Thereby, a seal member satisfying a sealing work object is selected. That is, the reliability of the selected seal can be ensured.

(4) The constructor 6 who has participated in the seal construction training in the support center 8 can perform seal construction on the seal construction object with the seal selected in the support center 8. As a result, the sealing operation can be performed with higher accuracy and higher reliability.

Example 1

Fig. 25 a shows a flange fastening practice device 80-1 of embodiment 1. In this flange tightening practice device 80-1, the device main body 222 includes the 1 st seal working portion 224-1 and the 2 nd seal working portion 224-2, each of the seal working portions 224-1 and 224-2 includes flange joints having different diameters, and the gaskets 228-1 and 228-2 are interposed between the flanges 226, and a plurality of bolts 230 and nuts 232 are provided. The trainer, for example, uses a torque wrench as a construction tool to sequentially tighten the nuts 232 to perform sealing construction.

As shown in B of fig. 25, each bolt 230 is provided with a strain sensor 234. Each strain sensor 234 detects an axial force generated in the bolt 230 due to the tightening torque τ of the nut 232.

The sensor output is taken into the PC 82 via a data logger 84 (fig. 10). The PC 82 displays the axial force in the tightening in real time on the display 86 using a polygon figure indicating the magnitude of the axial force in distance from the center.

In the practice using this flange fastening practice device 80-1, a trainer is made to recognize the deviation of fastening due to the construction tool, the relativity of the axial force of the adjacent bolts due to the interaction of the fastening force and elasticity, the one-sided fastening due to the improper fastening process, and the like, and to grasp important matters such as the fastening force, the fastening process, and the like for performing the function of the gasket. The training results are saved in association with the trainer in the construction training information sheet 112.

Example 2

FIG. 26A shows a creep reduction practice device 80-2 of example 2. In a of fig. 26, the same reference numerals are given to the same parts as those of fig. 25. In this creep reduction practice apparatus 80-2, heaters 236-1 and 236-2 are provided in the pipe portion 235 with the seal Shi Gongbu-224-3 interposed therebetween, respectively. The heaters 236-1 and 236-2 may be heat transfer heaters.

A spacer 228 is interposed between the flanges 226, and a plurality of bolts 230 and nuts 232 are provided. As shown in B of fig. 26, each bolt 230 is provided with a strain sensor 234.

In the creep reduction practice, an operation mode such as high-temperature operation and cyclic operation is simulated as an operation condition for gaskets made of different materials, and a change in axial force after fastening is detected by each strain sensor 234. The high-temperature operation and the cyclic operation may be simulated by using temperature changes based on temperature control of the heaters 236-1 and 236-2.

In this creep reduction practice device 80-2, the surface pressure drop after tightening, which is not observed in the actual machine, is detected in real time as an axial force change, and the axial force change is displayed. Thus, the trainer can recognize the surface pressure drop and grasp the initial tightening force and the effective time of tightening.

Example 3

Fig. 27 shows a sealability practicing device 80-3 of embodiment 3. In fig. 27, the same reference numerals are given to the same parts as those in fig. 25. In the seal performance practicing device 80-3, the device main body 222 includes the 1 st seal working portion 224-1 and the 2 nd seal working portion 224-2, and a plurality of bolts 230 and nuts 232 with a gasket 228 interposed between the flanges 226.

The flange 226 on the closed side, which is located on the top side of the device main body 222, is provided with a pressurizing device 238 for pressurizing the inside of the device main body 222, and a pressure sensor 239 for detecting the pressure inside the device main body 222. The pressure sensor 239 detects a pressure change due to the seal deterioration of the seal working portions 224-1, 224-2.

The tightness of the seals Shi Gongbu-1, 224-2 is affected by the flange 226, gasket 228, bolts 230. Damage, surface roughness, and corrosion of the surface of the flange 226 affect the sealability of the gasket 228, and damage, adhesion of foreign matter such as dust, etc. to the surface of the gasket 228 affect the sealability of the gasket 228, and rust and lubricating materials affect the sealability of the gasket 228 in the bolts 230.

In this sealing performance practicing device 80-3, the failure due to each state of the flange 226, the gasket 228, or the bolt 230 can be reproduced, and the training person can grasp the leakage check method.

Example 4

FIG. 28 shows a field simulation fastening practice device 80-4 of example 4. In fig. 28, the same reference numerals are given to the same parts as those in fig. 25. In the site simulation fastening practice device 80-4, a sealing construction site under severe conditions is simulated in a sealing construction operation, so that a trainer can grasp the sealing construction.

In the sealing construction site, sealing construction under severe conditions such as high places, narrow places, barriers and the like can be forced. In addition to the high points, for example, the piping, the shelves, the structures, the facilities, and the like are complicated, and there is a small space. As shown in a of fig. 28, there are cases where plural pipes 240-1, 240-2, 240-3 are adjacent to each other and flange joints 242-1, 242-2, 242-3 as seal work portions are adjacent to each other. As shown in fig. 28B, a plurality of pipes 240-4 and 240-5 may be adjacent to each other and intersect each other, and flange joints 242-4 and 242-5 serving as seal work portions may be adjacent to each other at the intersection. 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 disposed adjacent to the structure 244. Such a site situation of the sealing work is assumed, and the sealing work site assumed by the high place, the narrow place, the obstacle, etc. is freely reproduced in the site simulation tightening practice device 80-4, so that the trainer can grasp the sealing work under severe conditions that hinder the workability.

Example 5

Fig. 29 shows a piping calibration practice apparatus 80-5 of example 5. In fig. 29, the same reference numerals are given to the same parts as those in fig. 25. In the field of sealing construction, the following situations are encountered: as shown in fig. 29 a, the flanges 226 of the pipes 240-11 and 240-12 to be connected are widely spaced apart; as shown in fig. 29B, the interval between the flanges 226 of the pipes 240-11 and 240-12 is narrow; as shown in fig. 29C, the flanges 226 of the pipes 240-11 and 240-12 are inclined, and therefore cannot be parallel to each other; as shown in D of fig. 29, the flanges 226 of the pipes 240-11 and 240-12 are eccentric. In this case, even if the gasket 228 is fastened with a uniform fastening force, an appropriate fastening force cannot be transmitted to the gasket. In the piping calibration practice device 80-5, clearances, slopes, decentrations, and the like are freely set, and actual misalignment is reproduced, so that a trainer can practice sealing work for which the misalignment is not solved. For these cases, the fastening (surface pressure) condition of the trainer was evaluated.

Example 6

The structure of the heat exchanger is more complicated than a general flange for pipe connection, and the construction of the seal requires understanding of the structure of the heat exchanger. In the fixed tube sheet, since 2 gaskets are sandwiched between flanges and fastened, one-sided fastening is easily generated. In the large-diameter flange, the number of bolts is large, and the decrease in the fastening force between adjacent bolts in fastening due to elastic interaction between the flanges cannot be ignored. In addition, when the pipe flange/shell flange is eccentric, the partition plate cannot enter the groove and is located above the groove, which is a problem. Such special constructions require the most appropriate tightening force, proper selection of the construction tool, and the tightening process.

In this heat exchanger practicing device, the heat exchanger is put into a disassembled state, and a trainer is put into practice to perform the bolt fastening of the fixed tube sheet, the core alignment of the tube flange/the shell flange, and the like, which are required at the time of the sealing work.

Example 7

In the compression fracture practice device, a training person is made aware of compression fracture of the gasket or the like due to excessive tightening or the like. Regarding compression fracture, the conditions that the compression fracture is likely to occur are reproduced for the type of gasket, paste application, small diameter flange, etc., so that the trainee can grasp the cause of leakage and prevent it. For example, the following may be mentioned: in compression fracture of the expanded graphite sheet gasket, the surface pressure of the expanded graphite sheet gasket is lower than that of other gaskets; in paste coating, sealability is improved, but compression failure is easily generated; and in the small diameter flange, the gasket area is small relative to the number of bolts, and the surface pressure is liable to rise, so that compression failure is liable to occur.

Therefore, in this compression fracture practice apparatus, the training person can grasp the relationship between the type of gasket, the presence or absence of the paste, and the crack deformation, crack, or the like, which is the main cause of the compression fracture, with respect to the compression fracture, which is the main cause of the leakage.

Example 8

In other embodiments, torque feel practices, seal gasket practices for solid state rotary pumps, seal gasket practices for solid state valves are used. In the torque feel practicing device, the training person can be made to experience variations in tightening torque and axial force with respect to a plurality of bolts and nuts that differ in tightening conditions.
