Description

[Technical field]

[0001] The present invention relates to a gasket dimension proposal system, for example, that receives input information such as the type of gasket, the operating pressure, the seat shape of the flange on which the gasket is to be installed, and the dimensions of the flange from a user terminal, calculates gasket-related dimensions that reflect the input information, and provides the calculated gasket-related dimensions to the user terminal. [Background technology]

[0002] In recent years, various systems have been proposed to assist users who are considering using sealing materials such as gaskets in selecting a sealing material, thereby reducing the burden on the users.

[0003] For example, Patent Document 1 discloses a recommended sealant selection system that accepts sealant usage conditions (fluid type, pressure, temperature) from a user terminal, selects a sealant (sealing material) that corresponds to the accepted usage conditions, and provides information indicating the selected sealant to the user terminal. Furthermore, Patent Document 2 discloses a sealing material selection system that receives the "cross-sectional shape and material of the sealing material" from a user terminal, selects a sealing material that corresponds to the received "cross-sectional shape and material of the sealing material," and provides information indicating the selected sealing material to the user terminal.

[0004] Patent Document 3 discloses a sealing material selection device that selects a sealing material to be interposed between a mounting member and a mounting component. This sealing material selection device is configured to estimate the deformation amount of the mounting component and the compression rate of the sealing material after the mounting component is attached, and the mounting load required when attaching the mounting component to the mounting component, based on "shape data of the mounting component, mounting component, and sealing material" and "characteristic information of the sealing material", and to select an appropriate sealing material according to the estimation results.

[0005] Furthermore, Patent Document 4 discloses a gasket tightening calculation system that receives a gasket designation from a user device, as well as the size, pressure, and type of internal fluid of the gasket, calculates a tightening torque using the received information, and presents the tightening torque to the user device in association with the designated gasket.

[0006] [Patent Document 1] WO2015 / 156304 [Patent Document 2] JP 2016-091349 A [Patent Document 3] JP 2007-133496 A [Patent Document 4] JP 2015-017639 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, once a sealing material such as a gasket (type of sealing material) is selected by the systems shown in the above-mentioned Patent Documents 1 to 3, the user must then carry out the task of determining the dimensions of the sealing material. Specifically, currently, users make inquiries to the manufacturer's personnel by email or telephone and explain the conditions (conditions such as type of gasket, flange seat shape, pressure of the fluid used, flange dimension information, etc.). Each time an inquiry is received, the manufacturer's personnel individually calculates the gasket dimensions and flange dimensions that correspond to the conditions presented by the user, or selects gasket dimensions and flange dimensions defined in a standard (such as JIS standard) that meets the conditions, and responds to the user by email or telephone with the gasket dimensions and flange dimensions. In other words, currently, users obtain gasket dimensions through a person, which is time-consuming and takes time (about 1 to 2 days). In addition, the manufacturer's personnel must individually respond to inquiries from users, which places a heavy burden on the labor.

[0008] The present invention has been made in consideration of the above problems, and has as its object to provide a gasket dimension proposal system that calculates and provides gasket dimensions in response to a request from a user terminal. [Means for solving the problem]

[0009] The present invention, which has been made to solve the above problems, is a gasket dimension proposal system having a server device which provides gasket-related dimensional information including gasket dimensions to a user terminal of a user who is considering using a gasket via a network, the server device comprising: a gasket standard information database which stores gasket type information indicating the type of gasket, a pressure rating, a flange seating surface shape, and gasket standard information regarding gaskets defined in a predetermined standard in association with each other; and an information providing unit which provides the gasket-related dimensional information to the user terminal, the gasket standard information including the dimensions of the gasket, the dimensions of a flange on which the gasket is to be installed, and the dimensions of a bolt used to install the gasket, and the dimensions of the flange including a flange outer diameter and a pipe inner diameter. the input information including the gasket type information, the flange seating surface shape, the pressure value of the fluid to be used, and flange dimensional information is accepted from the user terminal, gasket standard information database is read out, which is associated with the gasket type information and the flange seating surface shape included in the accepted input information, a pressure rating that satisfies the pressure value included in the input information, and a flange dimension that has a small difference from the flange dimensional information included in the input information, and dimensions of the gasket that reflect the input information are calculated using the read out gasket standard information and the flange dimensional information of the input information accepted from the user terminal, and the information providing unit provides gasket-related dimensional information including the calculated gasket dimensions to the user terminal. In addition, it is desirable that the information providing unit is configured to calculate dimensions of the gasket that maintain the gasket width defined by the specified standard and that include a gasket outer diameter and a gasket inner diameter.

[0010] In this manner, in the gasket dimension proposal system of the present invention, the server device accepts input information regarding the gasket (input information including gasket type information, flange seat shape, pressure value of the fluid used, and flange dimension information) from the user terminal. Then, when the server device receives input information, it reads out gasket standard information corresponding to the received input information from the gasket standard information database, and uses the read out gasket standard information and the flange dimension information of the received input information to calculate the dimensions of the gasket reflecting the input information, and provides the dimensions to the user terminal. Therefore, according to the present invention, if a user operates a user terminal to transmit and input "input information including gasket type information, flange seating surface shape, pressure value of the fluid to be used, and flange dimensional information" to the server device, the server device provides the user terminal with gasket-related dimensional information including gasket dimensions reflecting the input information input by the user. In other words, according to the present invention, the user is provided with gasket-related dimensional information including dimensions of a special specification gasket corresponding to the input information input by the user.

[0011] Furthermore, according to the present invention, a user considering using a gasket no longer needs to obtain dimensional information of a gasket that meets the desired conditions through a human being, as is the case in the current business environment, thereby reducing the burden on the user. Furthermore, according to the present invention, the manufacturer's personnel are freed from the task of individually answering inquiries about gasket dimensions from users, as is the case in the current business environment, and the workload of the manufacturer's personnel is significantly reduced.

[0012] The information providing unit is configured to receive, as the flange dimension information of the input information, any one of a flange outer diameter only, a pipe inner diameter only, and both the flange outer diameter and the pipe inner diameter. When only the flange outer diameter is received as the flange dimension information of the input information, the information providing unit calculates a pipe inner diameter using the read gasket standard information and the flange outer diameter received from the user terminal, generates the gasket-related dimension information including the calculated gasket dimension and pipe inner diameter and the received flange outer diameter, and It is preferable that, when only the pipe inner diameter is received as the input information, the flange outer diameter is calculated using the read gasket standard information and the pipe inner diameter received from the user terminal, and the gasket-related dimensional information is generated including the calculated gasket dimension, the flange outer diameter, and the received pipe inner diameter, and, when both the flange outer diameter and the pipe inner diameter are received as the flange dimension information of the input information, the gasket-related dimensional information is generated including the calculated gasket dimension, the flange outer diameter, and the received flange outer diameter and pipe inner diameter.

[0013] According to the present invention, a user considering using a gasket can receive gasket-related dimensional information from a server device as long as at least one of the flange outer diameter and the pipe inner diameter is known for the flange dimensional information on the machine on which the gasket will be installed. Also, when a user inputs only the flange outer diameter as the flange dimension information from a user terminal to a server device, the user terminal can obtain from the server device the nonstandard pipe inner diameter reflecting the input information. Also, when a user inputs only the pipe inner diameter as the flange dimension information from a user terminal to a server device, the user terminal can obtain from the server device the nonstandard flange outer diameter reflecting the input information.

[0014] In addition, it is desirable that the information providing unit extracts the dimensions of a gasket of the specified standard, and the flange outer diameter and pipe inner diameter of the specified standard from the read gasket standard information, and generates the gasket-related dimensional information including the calculated gasket dimensions, the extracted dimensions of a gasket of the specified standard, the flange outer diameter, and the pipe inner diameter. The gasket-related dimensional information preferably includes a gasket outer diameter, a gasket inner diameter, a flange outer diameter, and a pipe inner diameter.

[0015] According to the above configuration, a user considering using a gasket can obtain "gasket dimensions, flange outer diameter, and pipe inner diameter" of a predetermined standard close to the input information, along with the gasket dimensions reflecting the input information input by the user. Therefore, the user can consider the gasket dimensions by comparing the gasket-related dimensions outside the predetermined standard reflecting the input information input by the user with the gasket-related dimensions of the predetermined standard close to the input information. Effect of the Invention

[0016] According to the present invention, it is possible to provide a gasket dimension proposal system that calculates and provides gasket dimensions in response to a request from a user terminal. [Brief description of the drawings]

[0018] Hereinafter, a gasket dimension proposal system according to an embodiment of the present invention will be described with reference to the drawings.

[0019] <Overall configuration of the gasket size proposal system> First, the overall configuration of the gasket dimension proposal system of the present embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram of a gasket dimension proposing system according to an embodiment of the present invention.

[0020] As shown in Figure 1, the gasket dimension proposal system of this embodiment includes a server device (hereinafter simply referred to as "server") 100 connected to a user terminal UT of a user who is considering using a gasket via a network NW such as the Internet.

[0021] The server 100 provides a "website for calculating gasket-related dimensions" to the user terminal UT via the network NW. The server 100 also accepts "input information such as gasket type information indicating the type of gasket, flange seat shape, pressure value of the fluid used, and flange dimension information" from the user terminal UT on the website. Upon accepting the input information, the server 100 calculates gasket-related dimensions corresponding to the accepted input information, and provides gasket-related dimension information indicating the calculated gasket-related dimensions to the user terminal UT. The gasket-related dimension information provided by the server 100 includes at least "gasket outer diameter, gasket inner diameter, flange outer diameter, and pipe inner diameter."

[0022] In addition, the user terminal UT is composed of an information processing device (such as a personal computer or smartphone) that has a control unit 30 with a web browser function, a communication processing unit 31 that transmits and receives various information with the server 100 via the network NW, an input unit 32 composed of a keyboard, operation buttons, a touch panel, etc., and a display unit 33 composed of an organic EL display, etc.

[0023] The user terminal UT then accesses the server 100 via the network NW, receives a "Web page constituting a website for calculating gasket-related dimensions" transmitted from the server 100, and displays the "Web page" on the display unit 33. The user terminal UT also accepts input of information required for calculating the gasket-related dimensions on the "Web page" via the input unit 32 (input information such as gasket type information, flange seating surface shape, pressure value of the fluid used, and flange dimension information). The user terminal UT then transmits the accepted input information to the server 1. In addition, the user terminal UT receives a “Web page presenting information indicating the gasket-related dimensions calculated based on the input information” sent from the server 1, and displays the Web page presenting information indicating the gasket-related dimensions on the display unit 33. In addition, since the user terminal 3 in this embodiment is an information processing device (information processing device such as a personal computer or a smartphone) that is well known in the art, a detailed description thereof will be omitted.

[0024] The server 100 also includes a control unit 10 that controls the operation of the entire device, a gasket information providing unit 11, and a storage unit 20 that stores various data. The storage unit 20 stores databases (a first gasket standard information database 21, a second gasket standard information database 22) in which data for calculating gasket dimensions is registered. The first gasket standard information database 21 and the second standard information database 22 store gasket standard information on gaskets defined by predetermined standards such as JIS standards.

[0025] Furthermore, the gasket information providing unit 11 provides the user terminal UT with a "Website for calculating gasket-related dimensions" and receives (accepts) input information sent from the user terminal UT. Furthermore, the server 100 calculates gasket-related dimensions using the received input information and a database (the first gasket standard information database 21 or the second gasket standard information database 22) stored in the storage unit 20, and provides information indicating the calculated gasket-related dimensions to the user terminal UT.

[0026] The gasket information providing unit 11 is configured to calculate two types of gasket-related dimensions, namely, "recommended gasket-related dimensions" and "compact gasket-related dimensions", as the gasket-related dimensions calculated in accordance with the input information received from the user terminal UT. "Recommended gasket-related dimensions" refer to the dimensions of the inner and outer diameters calculated from the width dimension of a specified standard (e.g., JIS standard) so as to match the input information while maintaining the gasket width (width dimension) specified in the specified standard. In addition, the "compact gasket-related dimensions" are width dimensions calculated so that the width dimension of the gasket is narrow (compact) in accordance with the input information.

[0027] Furthermore, there is no particular limitation on the hardware configuration of the server 1. For example, the server 1 is configured by a computer (one or more computers) equipped with a CPU (Central Processing Unit), a main memory device, an auxiliary memory device, an input / output I / F, and a communication I / F. The auxiliary storage device also stores programs for implementing the functions of each unit (control unit 10, gasket information providing unit 11). A storage unit 20 that stores a first gasket dimension information database 21 and a second gasket dimension information database 22 is formed in a predetermined area of ​​the auxiliary storage device. The functions of each unit (control unit 10, gasket information providing unit 11) are realized by the CPU loading the program stored in the auxiliary storage device into the main storage device and executing it.

[0028] <Names of gaskets, flanges and bolts> Next, the names of each part of the gasket G (Ga1, Ga2, Ga3, Gb1, Gb2, Gb3) that is the subject of the gasket-related dimensions calculated by the gasket dimension proposal system of this embodiment, and each part of the flange F and bolt on which the gasket G is installed will be explained for each gasket seat of the flange F on which the gasket G is installed.

[0029] <The gasket seat is a flat seat> First, the names of the gasket G, flange F, and bolts required for calculating the gasket dimensions when the gasket seat of the flange F on which the gasket G is installed is a flat seat will be described with reference to FIG. Here, FIG. 2 is a schematic diagram for explaining the names of each part of the gasket, flange, and bolt calculated by the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the names of each part when the gasket seat on which the gasket is placed is a flat seat.

[0031] {The gasket seat is a snap-in type} Next, the names of the gasket G, flange F, and bolts required for calculating the gasket dimensions when the gasket seat of the flange F on which the gasket G is installed is a fitting type will be described with reference to FIG. Here, FIG. 3 is a schematic diagram for explaining the names of each part of the gasket, flange, and bolt calculated by the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the names of each part when the gasket seat on which the gasket is placed is of a recessed type. In addition, (a) in FIG. 3 is a schematic diagram showing a state in which a sheet gasket Ga2 is installed on a flange F having a recessed gasket seat, (b) is a schematic diagram showing a state in which a spiral wound gasket Gb2 is installed on a flange F having a flat seat, and (c) is a schematic diagram showing the names of the parts shown in (a) and (b). In addition, in FIG. 3, the same components as those in FIG. 2 are denoted by the same reference numerals.

[0032] The names "1 to 6" and "II, IV" shown in FIG. 3 are the same as those in FIG. Also, as shown in Figure 3, "7 (circle 7)" indicates the "groove outer diameter clearance" and "I" indicates the "gasket outer diameter clearance" of flange F. In addition, the spiral wound gasket Gb2 in which the gasket seat is mounted on the flange F of the fitted type is not provided with an outer ring portion.

[0033] {The gasket seat is grooved} Next, the names of the gasket G, flange F, and bolts required for calculating the gasket dimensions when the gasket seat of the flange F on which the gasket G is installed is groove-shaped will be described with reference to FIG. Here, FIG. 4 is a schematic diagram for explaining the names of each part of the gasket, flange, and bolt calculated by the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the names of each part when the gasket seat on which the gasket is placed is groove-shaped. In addition, (a) in FIG. 4 is a schematic diagram showing a state in which a sheet gasket Ga3 is installed on a flange F having a groove-shaped gasket seat, (b) is a schematic diagram showing a state in which a spiral wound gasket Gb3 is installed on a flange F having a groove-shaped gasket seat, and (c) is a schematic diagram showing the names of the various parts shown in (a) and (b). In addition, in FIG. 4, the same components as those in FIG. 2 and FIG. 3 are denoted by the same reference numerals.

[0034] The names "1 to 7" and "I, II" shown in FIG. 4 are the same as those in FIG. Also, as shown in Figure 4, "8" indicates the "groove inner diameter clearance" and "V" indicates the "gasket inner diameter clearance" of flange F. In addition, the spiral wound gasket Gb3, in which the gasket seat is mounted on the groove-shaped flange F, is not provided with an inner ring portion and an outer ring portion.

[0035] <Explanation of the 1st and 2nd Gasket Standards Information Databases 21 and 22> Next, the databases (first and second gasket standard information databases 21, 22) provided in the server 100 of this embodiment will be described with reference to FIGS.

[0036] Here, FIG. 5 is a schematic diagram showing a first gasket standard information database provided in the server device of the gasket dimension proposal system of the present embodiment. FIG. 6 is a schematic diagram showing a second gasket standard information database provided in the server device of the gasket dimension proposal system of this embodiment.

[0037] The first gasket standard information database 21 is used to obtain numerical values ​​required for calculating the "recommended gasket-related dimensions and compact gasket-related dimensions" of sheet gaskets and the "recommended gasket-related dimensions" of spiral wound gaskets, and has registered therein values ​​for each part of the "gasket, flange, and bolt" defined by a prescribed standard (the illustrated example is the JIS standard). The second gasket standard information database 22 is used to obtain the numerical values ​​necessary for calculating the "compact gasket-related dimensions" of a spiral wound gasket, and has registered therein the values ​​of the various parts of the "gasket, flange, and bolt" defined by predetermined standards (JIS standards and gasket standards defined by arbitrary criteria in the illustrated example).

[0038] The first gasket standard information database 21 is a database that stores, in association with each other, "gasket type information indicating the type of gasket," "calculation pattern type," "pressure rating," "seat shape (flange seat shape information)," and gasket standard information (first standard information) regarding gaskets defined by a specified standard.

[0039] Specifically, as shown in FIG. 5, the first gasket standard information database 21 has a field 21a for registering "gasket type information indicating the type of gasket", a field 21b for registering "calculation pattern type", a field 21c for registering "pressure rating", a field 21d for registering "seat shape (flange seat shape information)", a field 21e for registering "flange outer diameter (D)", a field 21f for registering "bolt hole center circle diameter (C)", and a field 21g for registering "bolt hole diameter (h)". It is composed of a record (multiple records) having a field 21h for registering the "number of bolts (B1)", a field 21i for registering the "bolt thread diameter (B2)", a field 21j for registering the "pipe inner diameter (d)", a field 21k for registering the "RF seat diameter (g)", a field 21l for registering the "gasket inner diameter (d1)", a field 21m for registering the "gasket outer diameter (D1)", a field 21n for registering the "inner ring inner diameter (d4)", and a field 21о for registering the "outer ring outer diameter (D4)".

[0040] In the field 21a, either "sheet (sheet gasket)" or "spiral (spiral gasket)" is registered as "gasket type information". In field 21b, either "Pattern A" or "Pattern B" is registered as the "calculation pattern type." "Pattern A" indicates the calculation of "recommended gasket dimensions," and "Pattern B" indicates the calculation of "compact gasket dimensions." The "Pressure Rating" in field 21c is the nominal pressure of the flange in which the gasket is installed, and values ​​such as 5k, 10k, etc. are registered. In addition, in the field 21d, one of "flat seat", "inlay" and "groove" is registered as the "seat shape".

[0041] In addition, a record in which "sheet" is registered in field 21a and "pattern B" is registered in field 21b has the same numerical value as that specified for a gasket with a groove-shaped seating surface. This is because if the dimensions of the gasket and flange are calculated using this numerical value, the flange outer diameter, etc. can be set to a small (compact) size.

[0042] The second gasket standard information database 22 is a database that stores, in association with each other, "gasket type information indicating the type of gasket," "calculation pattern type," "seat shape (flange seat shape information)," "pressure rating," and gasket standard information (second standard information) regarding gaskets defined by a specified standard.

[0043] Specifically, as shown in FIG. 6, the second gasket standard information database 22 includes a field 22a for registering "gasket type", a field 22b for registering "calculation pattern type", a field 22c for registering "pressure rating", a field 22d for registering "seat surface shape", a field 22e for registering "flange outer diameter (D)", a field 22f for registering "diameter of bolt hole center circle (C)", a field 22g for registering "bolt hole diameter (h)", a field 22h for registering "number of bolts (B1)", a field 22i for registering "bolt thread diameter (B2)", a field 22j for registering "inner diameter of pipe (d)", a field 22k for registering "RF seat diameter (g)", a field 22l for registering "inner diameter of gasket (d1)", a field 22m for registering "outer diameter of gasket (D1)", a field 22n for registering "inner diameter of inner ring (d4)", and a field 22о for registering "outer diameter of outer ring (D4)", and is composed of records (multiple records).

[0044] The second gasket standard information database 22 is used to calculate the compact gasket dimensions of the "spiral gasket". Therefore, in the "gasket type" of field 22a, spiral X (expanded graphite), spiral Y (PTFE), spiral Z (inorganic paper (inorganic filler)), etc. are registered for each spiral gasket with different hoop materials, and only "pattern B" is registered in the "calculation pattern type" of field 22b.

[0045] Note that the types of data registered in fields 22c, 22d, 22e, 22f, 22g, 22i, 22j, 22k, 22l, 22m, 22n, 22о are the same as the types of data registered in fields 21c, 21d, 21e, 21f, 21g, 21i, 21j, 21k, 21l, 21m, 21n, 21о of the first gasket standard information database 21.

[0046] 《Outline Procedure for Calculation Process of Gasket-Related Dimensions》 Next, an outline of the procedure of the calculation process of gasket-related dimensions performed by the gasket information providing unit 11 of the server 100 of this embodiment will be described with reference to FIGS. Here, Fig. 7 is a flow chart showing the procedure of a process performed by the server device of the gasket dimension proposal system of this embodiment to calculate gasket-related dimensions and provide the calculation results to a user terminal. Fig. 8 is a schematic diagram for explaining an input process of input information received from a user terminal by the server device of the gasket dimension proposal system of this embodiment. Fig. 9 is a schematic diagram showing a Web page for inputting input information provided to a user terminal by the server device of the gasket dimension proposal system of this embodiment. Fig. 10 is a schematic diagram showing a Web page presenting gasket-related dimension information provided to a user terminal by the server device of the gasket dimension proposal system of this embodiment.

[0047] As shown in FIG. 7, in response to an access request from a user terminal UT, the gasket information providing unit 11 of the server 100 provides the user terminal UT with a "Web page constituting a website for calculating gasket-related dimensions" and accepts input information for calculating gasket-related dimensions from the user terminal UT (S1).

[0048] In this S1, as shown in FIG. 8, the gasket information providing unit 11 accepts input of gasket type information (S1A), accepts input of flange seating surface shape information (S1B), accepts input of pressure information (S1C), and accepts input of flange dimension information (S1D).

[0049] Specifically, in S1A, the gasket information providing unit 11 is configured to accept input of any one of "sheet gasket," "spiral wound gasket (expanded graphite)," "spiral wound gasket (PTFE)," "spiral wound gasket (inorganic paper)," etc. as "gasket type information." In S1B, the gasket information providing unit 11 is adapted to accept input of any one of "flat seat", "sandwich type" and "groove type" as "flange seat surface shape information". In S1C, the gasket information providing unit 11 is configured to accept an input of a user's arbitrary numerical value (unit: MPa) as the "pressure information". In S1D, the gasket information providing unit 11 is adapted to accept input of any one of "only the flange outer diameter", "only the pipe inner diameter", and "both the flange outer diameter and the pipe inner diameter".

[0050] Note that the gasket information providing unit 11 provides, for example, a Web page 400 shown in FIG. 9 to the user terminal UT as an input screen for accepting input of input information from the user terminal UT, and accepts input of input information from the user terminal UT.

[0051] The illustrated web page 400 has an area 401 for accepting input of gasket type information, an area 402 for accepting input of flange seat shape information, an area 403 for accepting input of pressure information (operating pressure), and an area 404 for accepting flange dimension information.

[0052] Also, area 404 is provided with a radio button to be selected when "the dimensions of the flange outer diameter and the pipe inner diameter are determined" and a radio button to be selected when "the dimensions of either the flange outer diameter or the pipe inner diameter are determined." The user operates the user terminal UT to select one of the two radio buttons. If the user selects the radio button for the case where "the dimensions of the flange outer diameter and the pipe inner diameter are determined", the user operates the user terminal to input values ​​for both the "flange outer diameter" and the "pipe inner diameter". On the other hand, if the user selects the radio button for the case where "the dimensions of either the flange outer diameter or the pipe inner diameter are determined", the user operates the user terminal to input a value for either the "flange outer diameter" or the "pipe inner diameter".

[0053] Furthermore, a search button 405 and a reset button 406 are provided at the bottom of Web page 400. After the user inputs the necessary input information in areas 401, 402, 403, and 404, the user operates user terminal UT to select (click) search button 405. This causes the input information to be transmitted from user terminal UT to gasket information providing unit 11 of server 100. Then, gasket information providing unit 11 of server 100 receives the input information transmitted from user terminal UT, and proceeds to the process of S2 in FIG. 7. If the user wishes to redo the input information entered in the areas 401, 402, 403, and 404, the user can clear the input information by operating the user terminal UT and selecting (clicking) a reset button 406.

[0054] Also, as shown in FIG. 7, in S2, the gasket information providing unit 11 of the server 100 accesses the first gasket dimension information database 21 and reads out gasket standard information (numeric values) for calculating recommended gasket-related dimensions corresponding to the input information received in S1.

[0055] Since S2 is a process for calculating recommended gasket-related dimensions, it reads out, from the group of records in which "Pattern A" is registered in field 21b of the first gasket dimension information database 21, gasket standard information associated with the "gasket type information" and "flange seat shape" included in the received input information, the "pressure rating that satisfies the pressure value" included in the input information, and the flange dimensions (flange outer diameter, pipe inner diameter) whose difference is small from the "flange dimension information" included in the input information.

[0056] For example, assume that the input information is "gasket type information is sheet gasket, flange seat surface shape information is flat seat, pressure information is 0.9 MPa, and flange dimension information is only flange outer diameter (φ88)". In this case, the gasket information provider 11 selects, from the records registered in the first gasket dimension information database 21, a record in which "sheet" is registered in field 21a, "pattern A" is registered in field 21b, "pressure rating that satisfies 0.9 MPa" is registered in field 21c, "flat seat" is registered in field 21d, and "flange outer diameter that is small in difference from the flange outer diameter (φ88)" is registered in field 21e, and reads out the gasket standard information registered in that record (numeric values ​​registered in fields 21e to 21o).

[0057] In S3, the gasket information providing unit 11 of the server 100 calculates recommended gasket-related dimensions using the gasket standard information (numeric values) read in S2 and the "flange dimension information" in the input information, and proceeds to processing in S4. The calculation procedures for calculating the recommended gasket-related dimensions will be explained in detail later.

[0058] In S4, the gasket information providing unit 11 of the server 100 reads out gasket specification information (numeric values) for calculating gasket-related dimensions from a different database, based on the gasket type information of the input information received in S1. If the gasket type information of the input information is “sheet gasket”, the gasket information providing unit 11 accesses the first gasket dimension information database 21 and reads out gasket standard information (numeric values) for calculating compact gasket-related dimensions corresponding to the input information received in S1. On the other hand, if the gasket type information of the input information is a "spiral wound gasket," the gasket information provider 11 accesses the second gasket dimension information database 22 and reads out gasket standard information (numeric values) for calculating the compact gasket-related dimensions corresponding to the input information received in S1.

[0059] For example, assume that the input information is "gasket type information is sheet, flange seat surface shape information is flat seat, pressure information is 0.9 MPa, and flange dimension information is only flange outer diameter (φ88)". In this case, the gasket information provider 11 selects, from the records registered in the first gasket dimension information database 21, a record in which "sheet" is registered in field 21a, "pattern B" is registered in field 21b, "pressure rating that satisfies 0.9 MPa" is registered in field 21c, "flat seat" is registered in field 21d, and "flange outer diameter that is small in difference from the flange outer diameter (φ88)" is registered in field 21e, and reads out the gasket standard information (numeric value) registered in that record.

[0060] In S5, the gasket information providing unit 11 of the server 100 calculates compact gasket-related dimensions using the gasket standard information (numeric values) read in S4 and the "flange dimension information" in the input information, and proceeds to processing in S6. The calculation procedure for calculating the compact gasket-related dimensions will also be described in detail later.

[0061] In S6, the gasket information providing unit 11 of the server 100 generates a Web page (gasket-related dimension presentation screen) presenting the recommended gasket-related dimensions calculated in S3 and the compact gasket-related dimensions calculated in S5, and provides the generated Web page (gasket-related dimension presentation screen) to the user terminal UT. In addition, this Web page (gasket-related dimension presentation screen) also presents "gasket-related dimensions of a predetermined standard that are close to the input information" in comparison with the calculated gasket-related dimensions. The gasket-related dimensions of the specified standard are obtained by selecting and extracting data corresponding to the calculated gasket-related dimensions from the data read out in S2 and S4.

[0062] 10 and transmits the Web page (gasket-related dimension presentation screen) 500 to the user terminal UT. The user terminal UT receives the Web page (gasket-related dimension presentation screen) 500 transmitted from the server 100 and displays it on the display unit 33.

[0063] The illustrated Web page (gasket-related dimension presentation screen) 500 has an area 500a for displaying input information entered by the user, and an area 500b for displaying gasket-related dimensions calculated using the input information. In addition, in area 500b, the calculated recommended dimensions, compact dimensions, and predetermined standard sizes that are close to the input information for the gasket inner diameter and gasket outer diameter are presented. In addition, in area 500b, the calculated reference dimensions, compact (non-standard) dimensions, and predetermined standard sizes that are close to the input information are presented for the flange outer diameter and the pipe inner diameter.

[0064] <<Specific calculation example of gasket-related dimensions calculation process>> Next, specific calculation examples of the calculation process for gasket-related dimensions will be described with some examples for both the recommended and compact gaskets.

[0065] <Gasket-related dimension calculation example 1 (recommended)> First, calculation example 1 (recommended) of gasket-related dimensions will be described with reference to Figs.

[0066] Here, FIG. 11 is a schematic diagram for explaining calculation example 1 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of extracting first gasket standard information (hereinafter referred to as first standard information) corresponding to input information received from a first gasket standard information database (hereinafter referred to as first standard information DB) in the calculation process of recommended gasket-related dimensions. FIG. 12 is a schematic diagram for explaining calculation example 1 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the dimensions of each part of the gasket, flange, and bolt using the first standard information extracted in response to the input information in the calculation process of the recommended gasket-related dimensions. FIG. 13 is a schematic diagram for explaining calculation example 1 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the gasket-related dimensions using input information and the dimensions of each part of the gasket and flange calculated from the first standard information extracted corresponding to the input information in the process of calculating the recommended gasket-related dimensions.

[0067] This calculation example 1 shows a calculation example when the received input information is "Gasket type information: spiral wound gasket", "Flange seat shape information: flat seat", "Pressure information: 0.9 MPa", and "Flange dimension information: flange outer diameter φ88 only" (input on one side). Note that Calculation Example 1 is an explanation of a calculation example of "recommended gasket-related dimensions", and the same processing will be performed even if the received gasket type information is "spiral wound gasket (expanded graphite)", "spiral wound gasket (PTFE)", or "spiral wound gasket (inorganic paper)". Therefore, in the explanation of Calculation Example 1, the "gasket type information" will be simply explained as "spiral wound gasket".

[0068] When the gasket information providing unit 11 of the server 100 receives input information from the user terminal UT, it accesses the first standard information database 21 and reads out the first standard information (numeric values) for calculating the recommended gasket-related dimensions corresponding to the received input information. 11, the gasket information provider 11 selects a record in which "spiral" is registered in field 21a, "pattern A" is registered in field 21b, "pressure rating that satisfies 0.9 MPa" is registered in field 21c, "flat seat" is registered in field 21d, and "flange outer diameter that is small in difference from the flange outer diameter (φ88)" is registered in field 21e from records registered in the first standard information database 21, and reads out the first standard information (numeric value) registered in that record. The read-out numerical value is data regarding gaskets, flanges, and bolts that is determined by a predetermined standard (JIS standard in the illustrated example).

[0069] In addition, when the gasket information provider 11 reads out the first standard information from the first standard information DB21, it uses the first standard information to calculate, as shown in FIG. 12, “1 (circle 1): flange outer diameter width,” “2 (circle 2): bolt outer clearance,” “3 (circle 3): bolt outer diameter,” “4 (circle 4): bolt inner clearance,” “5 (circle 5): gasket seat outer diameter clearance,” “6 (circle 6): pipe inner diameter clearance,” “II: gasket body width,” “III: outer ring width,” and “IV: inner ring width.”

[0070] Specifically, the gasket information providing unit 11 substitutes the read-out "flange outer diameter (D): 90," "diameter of bolt hole center (C): 65," and "bolt hole diameter (h): 15" into the following "Formula 1" to calculate "1: flange outer diameter width." Flange outer diameter width = (DCh) ÷ 2 (Formula 1) In calculation example 1, the "flange outer diameter width" is "5 (mm)".

[0071] In addition, the gasket information providing unit 11 substitutes the read-out “bolt hole diameter (h): 15” and “bolt thread diameter (B2): 12” into the following “Formula 2” to calculate “2: bolt outer clearance” and “4: bolt inner clearance”. Bolt outer clearance = (h-B2) ÷ 2 (Equation 2) Bolt outer clearance = Bolt inner clearance (Formula 2´) In calculation example 1, the "bolt outer clearance" and "bolt inner clearance" are "1.5 (mm)".

[0072] Further, the gasket information providing unit 11 changes the read "bolt thread diameter (B2): 12" to "3: bolt outer diameter."

[0073] In addition, the gasket information providing unit 11 substitutes the read “Bolt hole center diameter (C): 65”, “Bolt hole diameter (h): 15”, and “RF seat diameter (g): 46” into the following “Formula 3” to calculate “5: Gasket seat outer diameter clearance”. Flange outer diameter width = (Chg) ÷ 2 (Equation 3) In calculation example 1, the "gasket seat outer diameter clearance" is "2 (mm)".

[0074] Further, the gasket information providing unit 11 substitutes the read "inner ring inner diameter (d4): 18" and "pipe inner diameter (d): 12.7" into the following "Formula 4" to calculate "6: Pipe inner diameter clearance". Pipe inner diameter clearance = (d4-d) ÷ 2 (Equation 4) In calculation example 1, the "pipe inner diameter clearance" is "2.65 (mm)".

[0075] Further, the gasket information providing unit 11 substitutes the read "gasket outer diameter (D1): 37" and "gasket inner diameter (d1): 24" into the following "Formula 5" to calculate "II: gasket body width". Gasket body width = (D1-d1) ÷ 2 (Formula 5) In calculation example 1, the "gasket body width" is "6.5 (mm)".

[0076] The gasket information providing unit 11 substitutes the read "outer ring outer diameter (D4): 52" and "gasket outer diameter (D1): 37" into the following "Formula 6" to calculate "III: outer ring width." Outer ring width = (D4-D1) ÷ 2 (Equation 6) In this calculation example 1, the "outer ring width" is "7.5 (mm)".

[0077] The gasket information providing unit 11 substitutes the read "gasket inner diameter (d1): 24" and "inner ring inner diameter (d4): 18" into the following "formula (7)" to calculate "IV: inner ring width". Inner ring width = (d1-d4)÷2...(Formula 7) In this calculation example 1, the "inner ring width" is "3 (mm)".

[0078] In addition, the gasket information providing unit 11 calculates the dimensions (data) of each part of the gasket, flange, and bolt using the first standard information read out from the first standard information DB21, and then calculates recommended gasket-related dimensions using the calculated dimensions of each part, as shown in FIG. 13.

[0079] In addition, calculation example 1 shows the case where the flange dimension information in the input information is input on one side, but the calculation formula for the gasket-related dimensions will differ depending on whether only the outer diameter is input (input of the flange outer diameter) or only the inner diameter (input of the pipe inner diameter). Therefore, in the following, we will first explain the procedure for calculating gasket-related dimensions when only the outer diameter (flange outer diameter) is input, and then explain the procedure for calculating gasket-related dimensions when only the inner diameter (pipe inner diameter) is input.

[0080] <Calculation example 1: When only the outer diameter is entered> As shown in FIG. 13, the gasket information providing unit 11 calculates the “outer ring outer diameter” of the flange using the “flange dimension information: flange outer diameter φ88” of the input information received in S1 and “1 (circle 1): flange outer diameter part width”, “2 (circle 2): bolt outer clearance”, and “3 (circle 3): bolt outer diameter” obtained in FIG. 12.

[0081] Specifically, when only the outer diameter is input, as shown in "Formula 8" below, the "flange outer diameter" of the flange is calculated by subtracting the "additive and doubling of the 'flange outer diameter width', 'bolt outer clearance' and 'bolt outer diameter'" obtained from the gasket standard information from the "flange dimension information: flange outer diameter φ88" received from the user terminal UT. Outer ring outer diameter = (flange outer diameter (input value)) - ("flange outer diameter width" + "bolt outer clearance" + "bolt outer diameter") x 2 (Equation 8) In this calculation example, the "outer ring outer diameter" is 88-(5+1.5+12)×2=51 (mm).

[0082] In addition, the gasket information providing unit 11 calculates a recommended (non-standard) "gasket outer diameter (outer diameter dimension)" using the "outer ring outer diameter" obtained above and "III: outer ring width" obtained from the gasket standard information in Figure 12. Specifically, the gasket information providing unit 11 calculates the gasket outer diameter by subtracting twice the "outer ring width" from the "outer ring outer diameter" calculated by "Equation 8," as shown in "Equation 9" below. Gasket outer diameter = (outer ring outer diameter) - (outer ring width) x 2 (Equation 9) In this calculation example 1, the "gasket outer diameter" is "51-(7.5) x 2 = 36 (mm)".

[0083] In addition, the gasket information providing unit 11 calculates a recommended (non-standard) "gasket inner diameter (inner diameter dimension)" using the "gasket outer diameter" obtained above and "II: gasket body width" obtained from the first standard information (numerical value) in Figure 12. Specifically, the gasket information providing unit 11 calculates the gasket inner diameter by subtracting twice the "gasket body width" obtained from the numerical values ​​of the gasket standard information from the gasket outer diameter obtained by the above (Equation 9), as shown in the following "Equation 10". Gasket inner diameter = (Gasket outer diameter) - (Gasket body width) x 2 (Formula 10) In this calculation example 1, the "gasket inner diameter" is "36-(6.5)×2=23 (mm)".

[0084] In addition, the gasket information providing unit 11 calculates a recommended (non-standard) "inner ring inner diameter" using the "gasket inner diameter" obtained by (Equation 10) and "IV: inner ring width" obtained from the first standard information (numerical value) in Figure 12. Specifically, the gasket information providing unit 11 calculates the gasket inner diameter by subtracting twice the "inner ring width" obtained from the gasket standard information from the gasket inner diameter obtained by the above (Equation 10), as shown in the following "Equation 11". Inner ring inner diameter = (gasket inner diameter) - (inner ring width (IV)) × 2 (Equation 11) In this calculation example 1, the "inner ring inner diameter" is "23-(3)×2=17(mm)".

[0085] Further, the gasket information providing unit 11 calculates the pipe inner diameter using the "inner ring inner diameter" obtained by (Formula 11) and "6 (circle 6): pipe inner diameter clearance" obtained from the first standard information in FIG. Specifically, the gasket information providing unit 11 calculates the pipe inner diameter by subtracting twice the "pipe inner diameter clearance" obtained from the first standard information from the inner ring inner diameter obtained by the above (Equation 11), as shown in the following "Equation 12". Pipe inner diameter = (inner ring inner diameter) - (pipe inner diameter clearance) x 2 (Equation 12) In this calculation example 1, the "pipe inner diameter" is "17-(2.65) x 2 = 11.7 (mm)".

[0086] Thus, in the calculation example 1, when only the outer diameter was input, the "gasket outer diameter" became "36 (mm)" and the "gasket inner diameter" became "23 (mm)." These values ​​are the standard values ​​of the gasket width compared to the standard values ​​(gasket outer diameter: 37 (mm), gasket inner diameter: 24 (mm)) in the first standard information read from the first standard information DB21, and are gasket dimensions that differ from the predetermined standard reflected by the input information. In addition, in calculation example 1, the "pipe inner diameter" is "11.7 (mm)." This value is a pipe inner diameter dimension that differs from the specified standard reflected in the input information, compared to the standard value (pipe inner diameter: 12.7 (mm)) in the gasket standard information read from the first standard information DB21.

[0087] <Calculation example 1: When only the inner diameter is entered> When only the inner diameter is input, the gasket information providing unit 11 calculates the "inner ring inner diameter" of the gasket by adding "double the value of the "pipe inner diameter clearance" obtained from the first standard information" to the "flange dimension information: pipe inner diameter" received from the user terminal UT, as shown in "Equation 13" below. Inner ring inner diameter = (inner pipe diameter (input value)) + (inner pipe diameter clearance) × 2 (Equation 13)

[0088] In addition, the gasket information providing unit 11 calculates the "gasket inner diameter" by adding "double the value of the "inner ring width (IV)" obtained from the first standard information" to the "inner ring inner diameter" obtained by (Equation 13), as shown in "Equation 14" below. Gasket inner diameter = (inner ring inner diameter) + (inner ring width) × 2 (Equation 14)

[0089] In addition, the gasket information providing unit 11 calculates the "gasket outer diameter" by adding "the value obtained by multiplying the "gasket body width (II)" obtained from the gasket standard information by two" to the "gasket inner diameter" obtained by (Equation 14), as shown in "Equation 15" below. Gasket outer diameter = (gasket inner diameter) + (gasket body width) × 2 (Formula 15)

[0090] In addition, the gasket information providing unit 11 calculates the "outer ring outer diameter" by adding "double the value of the "outer ring width (III)" obtained from the first standard information to the "gasket outer diameter" obtained by (Equation 15), as shown in "Equation 16" below. Outer ring outer diameter = (gasket outer diameter) + (outer ring width) × 2 (Equation 16)

[0091] Further, as shown in the following "Equation 17", the gasket information providing unit 11 adds a value obtained by adding and doubling the "flange outer diameter portion width", "bolt outer clearance", and "bolt outer diameter" obtained from the first standard information to the "outer ring outer diameter" obtained in (Equation 16) to calculate the "flange outer diameter". Flange outer diameter = (outer ring outer diameter) + (flange outer diameter portion width + bolt outer clearance + bolt outer diameter) × 2 ··· (Equation 17)

[0092] In this way, the gasket information providing unit 11 calculates the recommended gasket-related dimensions as shown in Calculation Example 1. In the case of only inputting the outer diameter in Calculation Example 1, the gasket information providing unit 11 displays the input value for the flange outer diameter and presents the value obtained by the above calculation for the pipe inner diameter on the web page (gasket-related dimension presentation screen) 500 shown in FIG. 10. In the case of only inputting the inner diameter in Calculation Example 1, the gasket information providing unit 11 displays the input value for the pipe inner diameter and presents the value obtained by the above calculation for the flange outer diameter on the web page (gasket-related dimension presentation screen) 500 shown in FIG. 10.

[0093] 《Calculation Example 2 (Recommended) of Gasket-Related Dimensions》 Next, Calculation Example 2 (Recommended) of the gasket-related dimensions will be described with reference to FIGS. 14 and 15. In Calculation Example 2, the description of the same content as in Calculation Example 1 described above will be omitted (or simplified), and the different parts will be described in detail. Further, Calculation Example 2 is an explanation of an example of calculating the "recommended gasket-related dimensions". Therefore, in the description of Calculation Example 2, similar to the description of Calculation Example 1, the "gasket type information" will be simply described as a "spirally wound gasket".

[0094] Here, FIG. 14 is a schematic diagram for explaining calculation example 2 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the dimensions of each part of the gasket, flange, and bolt from the gasket standard information extracted in response to the input information in the calculation process of the recommended gasket-related dimensions. FIG. 15 is a schematic diagram for explaining calculation example 2 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the gasket-related dimensions using input information and the dimensions of each part of the gasket and flange calculated from the first standard information extracted corresponding to the input information in the process of calculating the recommended gasket-related dimensions.

[0095] This calculation example 2 shows a calculation example when the received input information is "Gasket type information: spiral wound gasket", "Flange seat shape information: flat seat", "Pressure information: 0.9 MPa", and "Flange dimension information: flange outer diameter φ88, pipe inner diameter φ11.7" (input from both sides).

[0096] Also in calculation example 2, when the gasket information providing unit 11 of the server 100 receives input information from the user terminal UT, it accesses the first standard information database 21 and reads out the first standard information (numerical values) for calculating the recommended gasket-related dimensions corresponding to the received input information. In calculation example 2, values ​​for both the flange outer diameter and the pipe inner diameter are entered as input information (both-sided input), and in such a case of both-sided input, the first standard information (numerical values) is read out to calculate the recommended gasket-related dimensions corresponding to the received input information, based on the outer diameter (flange outer diameter). In the second calculation example, the first standard information (numeric values) for calculating the recommended gasket-related dimensions read from the first standard information DB 21 are the same as those in the first calculation example.

[0097] Also, as shown in FIG. 14, in calculation example 2, the gasket information providing unit 11 calculates “1 (circle 1): flange outer diameter width,” “2 (circle 2): bolt outer clearance,” “3 (circle 3): bolt outer diameter,” “4 (circle 4): bolt inner clearance,” “5 (circle 5): gasket seat outer diameter clearance,” “6 (circle 6): pipe inner diameter clearance,” “II: gasket body width,” “III: outer ring width,” and “IV: inner ring width” using the numerical values ​​of the read out first standard information in a similar procedure to calculation example 1.

[0098] In addition, in Calculation Example 2, the formulas used to calculate "1 (circle 1): flange outer diameter width," "2 (circle 2): bolt outer clearance," "3 (circle 3): bolt outer diameter," "4 (circle 4): bolt inner clearance," "5 (circle 5): gasket seat outer diameter clearance," "6 (circle 6): pipe inner diameter clearance," "II: gasket body width," "III: outer ring width," and "IV: inner ring width" are the same as in Calculation Example 1 (using (Equation 1) to (Equation 7)).

[0099] Also, in calculation example 2, the gasket information providing unit 11 calculates the dimensions (data) of each part of the gasket, flange, and bolt using the gasket standard information read from the first standard information DB 21, and then calculates recommended gasket-related dimensions using the calculated dimensions of each part, as shown in FIG. 15.

[0100] The gasket information providing unit 11 calculates the "outer ring outer diameter," "gasket outer diameter," "gasket inner diameter," "inner ring inner diameter," and "pipe inner diameter" using the above-mentioned (Equation 8) to (Equation 12) in a calculation procedure similar to that in the above-mentioned calculation example 1 in which only the outer diameter is input.

[0101] In addition, the gasket information providing unit 11 compares the "pipe inner diameter" calculated using (formula 12) with the "pipe inner diameter (input value (11.7))" of the input information, and if the "pipe inner diameter" calculated using (formula 12) is equal to or greater than the "pipe inner diameter (input value)" of the input information, it determines that the calculated "pipe inner diameter" is acceptable. "Pipe inner diameter calculated using (Equation 12)" ≧ "Pipe inner diameter in input information (input value)" (Equation 18) Here, in calculation example 2, the “pipe inner diameter” is the same value as in calculation example 1, “11.7 (mm)”, which satisfies the above (Equation 18), so the calculated value is determined to be OK. In the case of input from both sides in calculation example 2, gasket information providing unit 11 displays the input values ​​for the flange outer diameter and pipe inner diameter on Web page (gasket related dimension presentation screen) 500 shown in FIG.

[0102] <Gasket-related dimension calculation example 3 (compact)> Next, a calculation example 3 (compact) of gasket-related dimensions will be described with reference to Figs.

[0103] Here, FIG. 16 is a schematic diagram for explaining calculation example 3 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of extracting gasket standard information corresponding to input information received from the first standard information DB in the calculation process of compact gasket-related dimensions. FIG. 17 is a schematic diagram for explaining calculation example 3 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the dimensions of each part of the gasket, flange, and bolt from the first standard information extracted in response to the input information in the compact gasket-related dimension calculation process. FIG. 18 is a schematic diagram for explaining calculation example 3 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating gasket-related dimensions using input information and the dimensions of each part of the gasket, flange, and bolt calculated from the first standard information extracted corresponding to the input information in the calculation process of compact gasket-related dimensions.

[0104] This calculation example 3 shows a calculation example when the received input information is "Gasket type information: sheet gasket", "Flange seat shape information: flat seat", "Pressure information: 0.9 MPa", and "Flange dimension information: flange outer diameter φ88 only" (input on one side).

[0105] When the gasket information providing unit 11 of the server 100 receives input information from the user terminal UT, it accesses the first gasket dimension information database 21 and reads out first standard information (numeric values) for calculating compact gasket-related dimensions corresponding to the received input information. Specifically, as shown in FIG. 16, the gasket information provider 11 selects from the records registered in the first standard information DB 21 a record in which “sheet” is registered in field 21 a, “pattern B” is registered in field 21 b, “pressure rating that meets 0.9 MPa” is registered in field 21 c, “flat seat” is registered in field 21 d, and “flange outer diameter that is small in difference from the flange outer diameter (φ88)” is registered in field 21 e, and reads out the first standard information (numeric value) registered in that record.

[0106] In addition, when the gasket information providing unit 11 reads out the first standard information defined by a specified standard (e.g., JIS standard) from the gasket dimension information database 21, it uses the first standard information defined by the specified standard to calculate “1 (circle 1): flange outer diameter width”, “2 (circle 2): bolt outer clearance”, “3 (circle 3): bolt outer diameter”, “4 (circle 4): bolt inner clearance”, “5 (circle 5): gasket seat outer diameter clearance”, “6 (circle 6): pipe inner diameter clearance”, and “II: gasket body width”, as shown in FIG. 17.

[0107] Specifically, the gasket information providing unit 11 calculates “1 (circle 1): flange outer diameter width”, “2 (circle 2): bolt outer clearance”, “3 (circle 3): bolt outer diameter”, “4 (circle 4): bolt inner clearance”, and “5 (circle 5): gasket seat outer diameter clearance” using the above-mentioned (Equations 1) to (Equations 3) in the same procedure as in the above-mentioned calculation example 1. The gasket information providing unit 11 also calculates "II: gasket body width" using (Formula 5) in the same manner as in Calculation Example 1 described above.

[0108] Furthermore, the gasket information providing unit 11 obtains "6 (circle 6): pipe inner diameter clearance" by substituting the read "gasket inner diameter (d1): 28" and "pipe inner diameter (d): 12.7" into the following "Formula 4'". Calculate “6: Pipe inner diameter clearance”. Pipe inner diameter clearance = (d1-d) ÷ 2 (Formula 4´) In calculation example 3, the "pipe inner diameter clearance" is "7.65 (mm)".

[0109] In addition, the gasket information providing unit 11 calculates the dimensions (data) of each part of the gasket, flange, and bolt using the first standard information read out from the first standard information DB21, and then calculates compact gasket-related dimensions using the calculated dimensions of each part, as shown in FIG. 18.

[0110] As with calculation example 1 described above, calculation example 3 shows the case where the flange dimension information in the input information is input on one side, so the calculation formula for the gasket-related dimensions differs depending on whether only the outer diameter is input (flange outer diameter input) or only the inner diameter (pipe inner diameter input). Therefore, in the following, we will first explain the procedure for calculating gasket-related dimensions when only the outer diameter (flange outer diameter) is input, and then explain the procedure for calculating gasket-related dimensions when only the inner diameter (pipe inner diameter) is input.

[0111] <Calculation example 3: When only the outer diameter is entered> As shown in FIG. 18, the gasket information providing unit 11 calculates the “gasket outer diameter” of the flange using the “flange outer diameter φ88” of the input information received in S1 and “1 (circle 1): flange outer diameter width,” “2 (circle 2): bolt outer clearance,” and “3 (circle 3): bolt outer diameter” obtained in FIG. 17.

[0112] Specifically, the gasket information providing unit 11 calculates the "gasket outer diameter" by subtracting the "addition and doubling of the 'flange outer diameter width', 'bolt outer clearance', and 'bolt outer diameter'" obtained from the gasket standard information read from the first standard information DB21 from the "flange outer diameter (input value)" of the input information, as shown in the following (Equation 19). Gasket outer diameter = (Flange outer diameter (input value)) - ("Flange outer diameter width" + "Bolt outer clearance" + "Bolt outer diameter") x 2 (Formula 19)

[0113] In addition, the gasket information providing unit 11 calculates the compact (non-standard) "gasket inner diameter (inner diameter dimension)" using the "gasket outer diameter" calculated by the above (Equation 19) and "II: gasket body width" calculated from the first standard information in FIG. 17. Specifically, the gasket information providing unit 11 calculates the gasket inner diameter by subtracting twice the "gasket body width" from the "gasket outer diameter" calculated by "equation 19," as shown in "equation 20" below. Gasket inner diameter = (Gasket outer diameter) - (Gasket body width) × 2 (Equation 20)

[0114] In addition, the gasket information providing unit 11 calculates the "pipe inner diameter" of the compact using the "gasket inner diameter" calculated by the above (Equation 20) and "6: Pipe inner diameter clearance" calculated from the first standard information in FIG. 17. Specifically, the gasket information providing unit 11 calculates the gasket inner diameter by subtracting twice the "pipe inner diameter clearance" obtained from the first standard information from the "gasket inner diameter" obtained by the above "formula 20" as shown in the following "formula 21". Pipe inner diameter = (gasket inner diameter) - (pipe inner diameter clearance) × 2 (Equation 21)

[0115] <Calculation example 3: When only the inner diameter is entered> When only the inner diameter is input, the gasket information providing unit 11 calculates the "gasket inner diameter" by adding the "flange dimension information: pipe inner diameter (input value)" received from the user terminal UT and the "value obtained by multiplying the 'pipe inner diameter clearance'" obtained from the first standard information, as shown in "Equation 22" below. Gasket inner diameter = (pipe inner diameter (input value)) + (pipe inner diameter clearance) × 2 (Equation 22)

[0116] In addition, the gasket information providing unit 11 calculates the "gasket outer diameter" by adding the "value obtained by multiplying the "gasket body width (II)" obtained from the first standard information by two" to the "gasket inner diameter" obtained by (Equation 22) as shown in the following "Equation 23". Gasket outer diameter = (gasket inner diameter) + (gasket body width) × 2 (Equation 23)

[0117] In addition, the gasket information providing unit 11 calculates the "gasket outer diameter" by adding the "addition and doubling of the "flange outer diameter width", "bolt outer clearance", and "bolt outer diameter" obtained from the first standard information to the "gasket outer diameter" obtained by (Equation 23), as shown in "Equation 24" below. "Flange outer diameter" = (gasket outer diameter) + ((flange outer diameter width) + (bolt outer clearance) + (bolt outer diameter)) x 2 (Equation 24)

[0118] <Gasket-related dimension calculation example 4 (compact)> Next, calculation example 4 (compact) of gasket-related dimensions will be described with reference to Figs.

[0119] Here, FIG. 19 is a schematic diagram for explaining calculation example 4 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of extracting second gasket standard information (hereinafter referred to as second standard information) corresponding to input information received from a second gasket standard information database (hereinafter referred to as second standard information DB) in the compact gasket-related dimension calculation process. Moreover, FIG. 20 is a schematic diagram for explaining calculation example 4 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the dimensions of each part of the gasket, flange, and bolt from the second standard information extracted in response to the input information in the compact gasket-related dimension calculation process. Moreover, FIG. 21 is a schematic diagram for explaining calculation example 4 of the gasket-related dimension calculation process performed by the server device of the gasket dimension proposal system of this embodiment, and is a schematic diagram for explaining the process of calculating the gasket-related dimensions using input information and the dimensions of each part of the gasket, flange, and bolt calculated from the second standard information extracted corresponding to the input information in the calculation process of compact gasket-related dimensions.

[0120] This calculation example 4 (compact) shows a calculation example when the received input information is "Gasket type information: spiral wound gasket (expanded graphite)", "Flange seat shape information: flat seat", "Pressure information: 0.9 MPa", and "Flange dimension information: flange outer diameter φ88 only" (input on one side).

[0121] When the gasket type information of the input information received from the user terminal UT is a “spiral wound gasket” and the gasket information providing unit 11 of the server 100 calculates compact gasket-related information, the gasket information providing unit 11 accesses the second standard information DB 22 and reads out the second standard information (numerical values) for calculating the compact gasket-related dimensions corresponding to the received input information. Specifically, as shown in FIG. 19, the gasket information provider 11 selects, from the records registered in the second standard information DB 22, a record in which “Spiral X (expanded graphite)” is registered in field 22a, “Pattern B” is registered in field 22b, “Pressure rating that satisfies 0.9 MPa” is registered in field 22c, “Flat seat” is registered in field 22d, and “Flange outer diameter that is small in difference from the flange outer diameter (φ88)” is registered in field 22e, and reads out the second standard information (numeric value) registered in that record.

[0122] In addition, when the gasket information provider 11 reads out the second standard information corresponding to the input information from the second standard information DB22, as shown in FIG. 20, it uses the second standard information corresponding to the input information to calculate “1 (circle 1): flange outer diameter width”, “2 (circle 2): bolt outer clearance”, “3 (circle 3): bolt outer diameter”, “4 (circle 4): bolt inner clearance”, “5 (circle 5): gasket seat outer diameter clearance”, “6 (circle 6): pipe inner diameter clearance”, “II: gasket body width”, “III: outer ring width”, and “IV: inner ring width”.

[0123] Specifically, the gasket information providing unit 11 calculates "1 (circle 1): flange outer diameter width," "2 (circle 2): bolt outer clearance," "3 (circle 3): bolt outer diameter," "4 (circle 4): bolt inner clearance," "5 (circle 5): gasket seat outer diameter clearance," "6 (circle 6): pipe inner diameter clearance," "II: gasket body width," "III: outer ring width," and "IV: inner ring width" using the above-mentioned (Equations 1) to (Equations 7) in the same procedure as in the above-mentioned calculation example 1.

[0124] In addition, the gasket information provider 11 calculates the dimensions (data) of each part of the gasket, flange, and bolt using the second standard information read from the second standard information DB 22, and then calculates compact gasket-related dimensions using the calculated dimensions of each part, as shown in FIG. 21.

[0125] As with calculation example 1 described above, calculation example 4 shows the case where the flange dimension information in the input information is input on one side, so the calculation formula for the gasket-related dimensions differs depending on whether only the outer diameter is input (flange outer diameter input) or only the inner diameter (pipe inner diameter input). Therefore, in the following, we will first explain the procedure for calculating gasket-related dimensions when only the outer diameter (flange outer diameter) is input, and then explain the procedure for calculating gasket-related dimensions when only the inner diameter (pipe inner diameter) is input.

[0126] <Calculation example 4: When only the outer diameter is entered> In the case where only the outer diameter is input in Calculation Example 4, the gasket information providing unit 11 calculates the "outer ring outer diameter," "gasket outer diameter," "gasket inner diameter," "inner ring inner diameter," and "pipe inner diameter" as compact gasket-related dimensions using the above-mentioned (Equations 8) to (Equations 12) in the same procedure as in Calculation Example 1 described above.

[0127] <Calculation example 4: When only the inner diameter is entered> When only the inner diameter of calculation example 4 is input, the gasket information providing unit 11 calculates the compact gasket-related dimensions, i.e., the "inner ring inner diameter," "gasket inner diameter," "gasket outer diameter," "outer ring outer diameter," and "flange outer diameter," using the above-mentioned (Equations 13) to (Equations 17) in the same manner as in the above-mentioned calculation example 1.

[0128] As described above, in the gasket dimension proposal system of this embodiment, the server 100 accepts input information regarding the gasket (input information including gasket type information, flange seat shape, pressure value of the fluid used, and flange dimension information) from the user terminal UT. Then, when the server 100 receives input information, it reads out gasket standard information corresponding to the received input information from the gasket standard information database (the first gasket standard information database 21 or the second gasket dimension calculation database 22), and uses the read out gasket standard information and the flange dimension information of the received input information to calculate gasket-related dimension methods (gasket-related dimensions including gasket dimensions) that are outside the specified standard and reflect the input information, and provides gasket-related dimension information indicating the gasket-related dimensions to the user terminal UT.

[0129] Thus, according to this embodiment, if the user operates the user terminal UT to send "input information including gasket type information, flange seat shape, pressure value of the fluid to be used, and flange dimension information" to the server 100, the server 100 will provide the user terminal UT with gasket-related dimensional information including gasket dimensions reflecting the input information.

[0130] In other words, according to this embodiment, a user considering using a gasket no longer needs to obtain gasket dimensional information through a human being, such as by inquiring with a person in charge at a gasket manufacturer, as is the case in the current business environment, thereby reducing the burden on the user. Furthermore, according to this embodiment, the manufacturer's personnel are freed from the task of individually answering inquiries about gasket dimensions from users, as is the case in the current business environment, and the workload of the manufacturer's personnel is significantly reduced.

[0131] In addition, the server 100 calculates the recommended gasket-related dimensions that maintain the gasket width defined by a specified standard (e.g., JIS standard) and reflect the input information, as well as the compact gasket-related dimensions that are calculated to make the gasket width narrow (compact) in accordance with the input information. In addition, the server 100 also provides the user terminal UT with gasket-related dimensions of a specified standard that are close to the received input information on a web page that provides recommended gasket-related dimensions and compact gasket-related dimensions (see FIG. 11). Therefore, the user can determine the gasket-related dimensions to use from among the recommended gasket-related dimensions that maintain the gasket width defined by a specified standard (e.g., JIS standard) and reflect the input information, the compact gasket-related dimensions, and the gasket-related dimensions of a specified standard that are close to the input information entered by the user.

[0132] Furthermore, in this embodiment, a user considering using a gasket can receive gasket dimensional information from the server device as long as they know at least one of the flange outer diameter and the pipe inner diameter, which are the flange dimensional information on the machine on which the gasket will be installed. Furthermore, when a user inputs only the flange outer diameter as the flange dimension information from the user terminal UT to the server 100, the user terminal UT can obtain a reference pipe inner diameter reflecting the input information from the server 100. Furthermore, when a user inputs only the pipe inner diameter as the flange dimension information from the user terminal UT to the server 100, the user terminal UT can obtain a reference flange outer diameter reflecting the input information from the server 100. That is, according to this embodiment, the user can propose dimensions of the machine on which the gasket is to be installed.

[0133] As described above, according to this embodiment, it is possible to provide a gasket dimension proposing system that calculates and provides desired gasket dimensions in response to a request from a user terminal.

[0134] The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the present invention. For example, in the above-described embodiment, the server 100 provides both the recommended gasket-related dimensions and the compact gasket-related dimensions to the user terminal UT, but the present invention is not particularly limited to this. The server 100 may calculate only recommended gasket-related dimensions from the input information from the user terminal UT and the first gasket standard information registered in the first gasket standard information database 21, and provide it to the user terminal UT. Alternatively, the server 100 may calculate only compact gasket-related dimensions from the input information from the user terminal UT and the first gasket standard information (or the second gasket standard information) registered in the first gasket standard information database 21 (or the second gasket standard information database 22), and provide it to the user terminal UT.

[0135] In addition, the specified standard of the gasket standard information of the specified standard registered in the first gasket standard information database 21 (or the second gasket standard information database 22) is as follows: The predetermined standard is not particularly limited. The predetermined standard may be the JIS standard exemplified in this application, or may be a JPI standard other than the JIS standard, or a standard related to gaskets established by a country or organization other than Japan (for example, the ASME standard in the United States, etc.).

[0136] In addition, in the above-described embodiment, the gasket information providing unit 11 of the server 100 calculates the gasket-related dimensions using the input information received from the user terminal UT and the first and second gasket standard information databases 21, 22, but this is not particularly limited to this. For example, the function of the gasket information providing unit 11 may be configured so as to only transmit and receive data with the user terminal UT, and the memory unit 20 of the server 100 may be provided with a calculation formula database storing the above-mentioned (Equations 1) to (Equations 24). Furthermore, the server 100 may be provided with a calculation unit that calculates gasket-related dimensions using input information received from the user terminal UT, the first gasket standard information (or the second gasket standard information) stored in the first and second gasket standard information databases 21 and 22, and the calculation formula stored in the calculation formula database. In this case as well, the same effects as those of the above-described embodiment can be obtained. [Explanation of symbols]
