The valve is the key equipment in the fluid conveying system, which is used to control the flow rate, direction, pressure, temperature and other parameters of the fluid to ensure the normal operation of the fluid conveying system. Valve type and letter code is an important sign of valve performance, structure, material and use information. This paper will discuss the evolution and standardization of valve models and letter codes from a professional perspective.
First, the evolution of valve models and letter codes
1. Evolution background
With the advancement of industrialization, valves are more and more widely used in petroleum, chemical industry, metallurgy, shipbuilding, construction and other fields. The demand for valves in different industries and different application scenarios is not the same, so the evolution and standardization of valve models and letter codes has become an inevitable trend in the development of the industry.
2. Evolution process
The evolution of valve models and letter codes has experienced a process from simple to complex, from chaotic to standardized. The early valve models and letter codes are relatively simple, mainly represented by numbers, such as “1″, “2″, “3″, etc., indicating different types of valves. With the continuous expansion of valve types and application fields, digital codes have been unable to meet the needs of the development of the industry, so the introduction of letter codes.
Modern valve models and letter code system is more perfect, not only including class code, transmission code, connection form code, structural form code, material code, working pressure code and valve body form code, and each code has a clear meaning and regulations.
Second, the standardization of valve models and letter codes
1. Standardization significance
The standardization of valve models and letter codes helps to improve the standardization and interchangeability of the design, manufacturing, selection and use of valve products, reduce industry costs and improve work efficiency. At the same time, standardization also helps to promote technological progress and innovation in the valve industry and promote the healthy development of the industry.
2. Standardization status
At present, a series of valve type and letter code standards have been developed at home and abroad. In China, mainly refer to GB/T 12220-2015 “Industrial valve type preparation method”, JB/T 7352-2017 “Valve type and letter code” and other standards. Internationally, mainly refer to ISO 5211:2017 “Industrial valve type preparation method” and other standards.
These standards have made detailed provisions on the composition, meaning and representation of valve models and letter codes, laying the foundation for the standardization of the valve industry.
Third, the future development trend of valve models and letter codes
1. Simplify and unify
With the development of global economic integration, international exchanges and cooperation in the valve industry are becoming more and more close. In order to facilitate the mutual recognition and communication of international valve models and letter codes, the future valve models and letter codes will be developed in the direction of simplification and unification.
2. Digital and intelligent
With the development of industry 4.0, intelligent manufacturing and other technologies, the valve industry will gradually realize digitalization and intelligence. Future valve models and letter codes may introduce more numbers and letter combinations to represent valve performance, function, communication interface and other information.
In short, the evolution and standardization of valve models and letter codes is an inevitable trend of the development of the valve industry, and an important embodiment of technological progress and innovation in the industry. Understanding the evolution and standardization of valve types and letter designations helps in the correct selection and use of valves to ensure the safe, reliable and efficient operation of fluid delivery systems.
