Here, the case of the processing of S13 and 14 is described by taking the case where "exhaust gas" is accepted as the fluid classification in S12.

In this case, the sealing material retrieval portion 11a is from the gasket. A record of "exhaust gas" is registered in the extracted field 18a1 in the graphic information database 18a. Further, the seal material search unit 11a acquires the "temperature-pressure pattern" from the extracted record. The obtained "temperature-pressure pattern" describes the recommended range of use of each sealing material that can be used in "exhaust gas" on a two-dimensional coordinate in which the temperature is the horizontal axis (x-axis) and the pressure is the vertical axis (y-axis). Lines R1, 2, 3, 4, 5 were obtained.

Further, the sealing material search unit 11a generates a use condition input page 102 (FIG. 12), and transmits it to the user terminal 3, in which the area 102a indicating the fluid classification accepted in S12 is formed, and the self-instruction is presented. The area 102b of the "temperature-pressure input pattern" for inputting temperature and pressure is accepted on the two-dimensional coordinates.

Conditions "Temperature (1st use condition)" and "Pressure (2nd use condition)".

Further, the area 102b is provided with the temperature input field 102b1 and the pressure input field 102b2, and the user of the user terminal 3 can directly input "temperature and pressure" to the temperature input field 102b1 and the pressure input field 102b2.

In the S12, when the sealing material search unit 11a receives the water, the hot water, and the water vapor as the fluid classification, the sealing material search unit 11 generates the use condition input page 102 (see FIG. 13) in S13 and S14. And transmitted to the user terminal 3, the usage condition input page 102 is described in "water, hot water, water vapor" on a two-dimensional graph in which the temperature is the horizontal axis (x-axis) and the pressure is the vertical axis (y-axis). The recommended range of use of each sealant is available.

Next, the processing of S15 will be described.

In S15, the seal material search unit 11a accepts input of the use condition (temperature, pressure) from the user terminal 3.

Specifically, when the user terminal 3 aligns the cursor C with the desired position on the coordinates of the "temperature-pressure input pattern" shown in the area 102b on the condition input page 102, and performs a click operation (or When the numerical value is directly input to the temperature input field 102b1 and the pressure input field 102b2, the value input in the temperature input field 102b1 and the pressure input field 102b2 of the use condition input page 102 is displayed (see FIG. 14). At this time, the values of the temperature and pressure input to the coordinates of the "temperature-pressure input pattern" are plotted.

When the user terminal 3 clicks the search button 102c on the use condition input page 102, the data indicating the value of the input "temperature and pressure" is transmitted to the sealing material search unit 11a. Further, the seal material search unit 11a receives the data indicating the value of "temperature and pressure" transmitted from the user terminal 3.

According to this configuration, the user of the user terminal 3 visually grasps the input range of the use condition (temperature, pressure), and can input the temperature and the pressure from the coordinates of the two-dimensional pattern (temperature-pressure input pattern) of the use condition input page 102, The selection of the sealing material can be performed more easily than the prior art system.

Further, in the use condition input page 102, since the recommended use range line of each of the gaskets usable in the fluid classification is described in the two-dimensional pattern, the user can confirm which of the recommended use conditions of the gasket is used. position.

When the seal material search unit 11a receives the data indicating the "temperature and pressure" transmitted from the user terminal 3, it is determined whether or not the necessary condition for the use condition is input (S16). Here, when both of "temperature and pressure" are not input, it is determined that the necessary items are not input.

When it is determined in S16 that the necessary item is not input, the sealing material search unit 11a transmits an "error message" to the user terminal 3 and displays it (S18), and then returns to the process of S11. When the sealing material search unit 11a determines that the necessary items of the use condition have been input, the process proceeds to S17.

In addition, in the case where it is determined that the necessary items of the use condition are not input, it is assumed that the user does not click on the coordinates of the two-dimensional figure in S15, and does not enter any of the temperature input field 102b1 and the pressure input field 102b2. The case where the value (or both) is input and the search button 102c is clicked.

Product number information, and product number information of the gasket corresponding to the value below the conditions of use (temperature, pressure) (lower classification).

In this way, by prompting the classification of the three-stage classification (satisfying the classification of the selected conditions, the superior classification, and the lower classification), it is possible to select a practical model corresponding to the purpose of use or the environment in which the gasket is used. For example, in the case of using a gasket in an environment where the conditions of use are greatly changed, the selection of the gasket of the superior classification can be considered in consideration of stability. Further, for example, in the case of an experimental or a frequent maintenance condition even if the life is short, it is possible to investigate the selection of the sealing material which has lowered the classification of the lower grade.

Moreover, the recommended sealing material prompting page 103 is provided with an area 103b for prompting the selected sealing material graphic information, wherein the selected sealing material graphic information is based on the temperature as the horizontal axis (x axis) and the pressure as the vertical axis (y axis).
