Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, in particular, to a ship pipeline valve selection method, system, medium and terminal. BACKGROUND

[0002] In the ship system pipeline, valves play a crucial role. They precisely control the pressure, flow rate, and flow direction of the fluid in the pipeline, ensuring the safe and efficient operation of the ship system pipeline and equipment. There are various types of ship pipeline valves, and according to different parameters such as valve type, valve body material, structure form, nominal pressure, and nominal diameter, there are hundreds of types. The complexity of the ship pipeline system itself further exacerbates the difficulty of valve selection. The ship pipeline system needs to transport various media, including fresh water, seawater, steam, fuel oil, lubricating oil, compressed air, etc., each of which has different requirements for valve performance and material. For example, valves in the seawater system need to have good corrosion resistance, while valves in the fuel oil system need to meet the requirements of fire and explosion prevention. This diverse media requirement makes the ship pipeline valve show significant diversity in terms of type and quantity. Commonly used valve types in ship systems include stop valves, stop-check valves, check valves, butterfly valves, and gate valves. These valves play different roles in various systems of the ship. For example, stop valves are mainly used to shut off or open the fluid in the pipeline, while check valves are used to prevent backflow of fluid. Butterfly valves and gate valves are widely used in large-diameter pipelines due to their unique structural characteristics.

[0003] However, in the shipbuilding process, designers often lack unified standards when selecting valves. Different designers may choose different valve standards and model specifications based on their experience and preferences, which results in a wide variety of valve application standards and model specifications. This non-uniform selection standard not only increases the complexity of valve procurement work, but also may lead to valve inventory accumulation. Due to the lack of unified management, the procurement department has difficulty accurately predicting and controlling the demand for valves, resulting in inventory accumulation of some valves, occupying a large amount of funds and storage space. In addition, the diversification of valve model specifications makes it difficult to control procurement costs, and it is easy to exceed the standard. Different valve standards and model specifications often correspond to different suppliers and price systems, and the procurement department has difficulty in effective cost control and supplier management when faced with numerous choices. This not only increases procurement costs, but also may affect the overall progress and quality of shipbuilding. SUMMARY

[0048] Embodiment One

[0049] The present embodiment provides a method for selecting a valve for a ship pipeline, which refers to Figures 1 to 5 The method comprises the following steps:

[0050] S100: establishing a standard database for selecting a valve for a ship pipeline, the standard database for selecting a valve for a ship pipeline comprising input parameters and output parameters, the input parameters at least comprising a valve type parameter, an application system parameter and a pipeline information parameter, and the output parameters at least comprising an output valve standard number, standard information and a valve specification model;

[0051] Establishing a standard database for valve selection in marine piping is a key step to realize efficient and standardized valve selection. The core of the database is to integrate and optimize the selection information of various valves in the marine piping system to ensure that designers can quickly and accurately select appropriate valves, thereby improving design efficiency, reducing costs, and improving system reliability. The input parameters of the standard database for valve selection in marine piping are the basis of the selection process, and these parameters directly affect the final selection results. The input parameters at least include application system parameters and pipeline information parameters. The application system parameters refer to the specific ship system to which the valve is applied, such as the steam system, the fuel oil service system, the high and low temperature fresh water cooling system, etc. The pipeline information parameters include the diameter of the pipeline, etc. The output parameters of the database are the specific embodiment of the selection results, providing clear selection guidance for designers. The output parameters at least include valve standard number, standard information, and valve specification and model. The valve standard number clearly identifies the specific national standard or industry standard that the selected valve follows, such as GB / T 587-2008, etc. The standard information is the detailed technical specifications and requirements corresponding to the standard number, including material, structure type, performance indicators, etc. The valve specification and model are the detailed information of the valve, such as size, pressure rating, connection form, etc. The standard database for valve selection in marine piping includes application system database, valve selectable standard database, and valve unified standard and specification and model database. The standard database for valve selection in marine piping is composed of multiple sub-databases, which are interrelated and collectively realize comprehensive valve selection functions. Specifically, referring to Figure 2 , according to the function of the valve, the commonly used valves in the ship system are classified, and the standard database for valve selection in marine piping includes valve type database, which specifically includes cutoff valve database, regulating valve database, safety valve database, check valve database, and distribution valve database. The valve type database contains multiple valve type parameters, such as cutoff valve, butterfly valve, gate valve, and ball valve, etc. under the cutoff valve database. Each valve type parameter includes application system database, valve selectable standard database, and valve unified standard and specification and model database.

[0052] Referring to Figure 3 , the application system database is established according to the classification of the marine piping system, covering each subsystem in the ship piping network, i.e. application system parameters, such as steam system, fuel oil service system, high and low temperature fresh water cooling system, etc. Each subsystem database stores key parameters specific to the system, such as medium type, design temperature, design pressure, etc., providing system-level constraints for valve selection. Referring to Figure 4 , the valve selectable standard database contains valve standard number, valve applicable medium, valve applicable temperature, valve type, nominal pressure, and nominal diameter, etc. Among them, the valve applicable medium and applicable temperature in the valve selectable standard database correspond to the medium type and design temperature in the application system database. Referring to Figure 5, the valve piece unified standard and specification database is based on the optional standard database, according to the nominal diameter (DN) and nominal pressure (PN), the valve piece material is unified and merged, so as to effectively simplify the valve piece type, optimize the selection system. Taking the stop valve as an example, for small diameter valve piece (DN40 and below), bronze casting process is superior to cast steel and cast iron in corrosion resistance and internal coating, especially suitable for seawater medium environment, which can effectively avoid corrosion problems, and the cost increase caused by material replacement is smaller. Therefore, GB / T 584-2008 (cast steel stop valve) and GB / T 590-2008 (cast iron stop valve) can be replaced by GB / T 587-2008 (bronze stop valve). However, the mechanical properties of bronze material are insufficient when PN4.0 and above, so steel valve should be selected in this pressure range. For medium and large diameter valve piece (DN50 and above), cast iron valve has comprehensive advantages in cost, casting process and corrosion resistance, which can cover part of the application range of original copper valve and steel valve. At the same time, considering the small difference in internal structure of valve body, PN0.6 is unified to PN1.0, and PN1.6 is unified to PN2.5, so as to further improve the universality of pressure grade. However, under the condition of PN1.6 and higher pressure, cast iron valve cannot meet the strength requirement, and steel valve should be used.

[0053] S200: configuring the ship pipeline valve selection standard database to be able to output corresponding output parameters according to input parameters;

[0054] Specifically, in order to realize the function of ship pipeline valve selection standard database, the internal logic of ship pipeline valve selection standard database needs to be configured and optimized in detail, so as to ensure that it can accurately output the corresponding selection result according to the input parameters.

[0055] S300: inputting the input parameters into the ship pipeline valve selection standard database to obtain the output parameters.

[0056] Specifically, the following steps are included:

[0057] S301: inputting the valve piece type parameter and the application system parameter into the ship pipeline valve selection standard database;

[0058] S302: calling the corresponding application system database according to the valve piece type parameter, and obtaining the design pressure in the application system database according to the application system parameter;

[0059] S303: obtaining the nominal diameter and nominal pressure of the valve piece according to the design pressure and pipeline information parameter;

[0060] S304: calling the valve optional standard database and the valve unified standard and specification database, and obtaining the valve standard number, the standard information and the valve specification according to the nominal diameter and the nominal pressure.

[0061] Specifically, comprising:

[0062] S3041: calling the valve optional standard database, and obtaining the actual valve standard number, the actual standard information and the actual valve specification according to the nominal diameter and the nominal pressure;

[0063] S3042: calling the valve unified standard and specification database, and obtaining the recommended valve standard number, the recommended standard information and the recommended valve specification according to the nominal diameter and the nominal pressure.

[0064] Firstly, the valve standard number and the standard information are obtained according to the nominal diameter and the nominal pressure, and then the recommended nominal pressure equal to or higher than the nominal pressure is selected based on the valve standard number and the standard information. Finally, the recommended valve standard number, the recommended standard information and the recommended valve specification are extracted and output in the valve unified standard and specification database according to the nominal diameter and the recommended nominal pressure. Specifically, on the premise that the valve unified standard and specification database has unified the valve material, referring to Figure 5 , firstly, the valve standard number is obtained according to the nominal diameter and the nominal pressure, and then the recommended nominal pressure is selected according to the annotation content in the table where the valve standard number is located in the valve unified standard and specification database. If a valve standard number is marked with “*”, it indicates that although the pressure specification exists in the current standard, from the technical, safety or economic point of view, it is recommended to use the higher nominal pressure (PN) grade specification. If a selection result is displayed as “ / ”, it indicates that the pressure specification does not exist in the current standard, in which case the system will recommend using the higher nominal pressure (PN) valve specification. According to the above rules, the recommended valve standard number, the recommended standard information and the recommended valve specification are finally output.

[0065] Embodiment two

[0066] Referring to Figures 2 to 6The embodiment provides a ship pipeline valve selection system, which comprises a data construction module, a database configuration and interface module and a parameter processing and query calling module. The data construction module is the basis of the whole selection system and is responsible for establishing and maintaining the ship pipeline valve selection standard database. The database is the core data source of the selection, and its structure and content directly affect the accuracy and efficiency of the selection. Specifically, the database construction module is used to establish the ship pipeline valve selection standard database, which comprises input parameters and output parameters. The input parameters at least comprise valve type parameters, application system parameters and pipeline information parameters. The output parameters at least comprise valve standard number, standard information and valve specification model. The database configuration and interface module is used to configure the ship pipeline valve selection standard database so as to output corresponding output parameters according to the input parameters. The database configuration and interface module comprises a parameter analysis module, a parameter mapping module and a logic judgment module. The parameter analysis module is used to analyze the input parameters. The parameter mapping module is used to map the analyzed input parameters to the corresponding database table and field of the ship pipeline valve selection standard database. The logic judgment module is used to judge the analyzed input parameters through a preset logic rule and filter out the output parameters meeting the requirements. The parameter processing and query calling module is used to input the input parameters into the ship pipeline valve selection standard database to obtain the output parameters.

[0067] In order to further improve the practicability and accuracy of the selection result, a result optimization module is specially designed in the ship pipeline valve selection system. The function of the module is to deeply analyze and optimize the output parameters obtained initially, so as to ensure that the finally recommended valve not only meets the basic technical requirements, but also achieves the best balance in cost, reliability and compatibility. The result optimization module firstly queries the ship pipeline valve selection standard database according to the input nominal diameter (DN) and nominal pressure (PN) to obtain the recommended valve standard number. The input nominal diameter (DN) and nominal pressure (PN) are matched with the records in the ship pipeline valve selection standard database, and the valve standard number meeting the conditions is found. The valve standard number meeting the matching conditions is extracted from the selectable standard database of the ship pipeline valve selection standard database as the preliminary recommended result. Further, in the ship pipeline valve selection system, the result optimization module firstly selects the recommended nominal pressure equal to or higher than the nominal pressure, and then extracts and outputs the recommended valve standard number, recommended standard information and recommended valve specification model from the valve unified standard and specification model database according to the nominal diameter and the recommended nominal pressure. Not only the selection result meeting the basic requirements is provided, but also the result is optimized and adjusted according to the specific mark to ensure the rationality and safety of the selection.
