At present, the control valves produced by domestic valve manufacturers have low technical content, short service life, and average quality. There are quite a few products, especially some products with special performance. There is a big gap in product structure and product quality, mainly power plants. High parameter regulating valve, pressure reducing valve and safety valve, high parameter regulating valve for petrochemical industry, metallurgy and metal sealing butterfly valve and ball valve.
With the rapid economic development, my country's investment in oil and gas, petrochemical, electric power, metallurgy, steel, municipal and other fields has been increasing, which has effectively promoted the sustainable development of the national economy and also brought to the gas stove solenoid valve control valve industry. An unprecedented opportunity. The development direction of the regulator is mainly intelligent, standardized, and energy-saving.
1. Smart type:
The intelligent valve mainly adopts intelligent functions such as intelligent locator and remote communication of operating status, which makes the management of the adjustment valve convenient, the fault diagnosis is easy, and the technical requirements for maintenance personnel are reduced. The application of the valve intelligent positioner can not only facilitate the change of the flow characteristics of the solenoid valve of the washing machine, but also improve the control quality of the control system. In this way, the requirements for flow characteristics can be simplified and standardized.
The intelligent function module realizes the matching of the characteristics of the controlled object, which greatly reduces the types and varieties of regulating valve products and simplifies the production process. In order to reduce the variety, there are also domestic manufacturers that produce full-function control valves. These double-coil solenoid valves will be continuously improved and tested and approved in production and the market.
2. Standardization:
In order to achieve interchangeability, the control valves produced by different valve suppliers of the same size and specifications can be interchanged, so that users do not need to spend a lot of time to choose a manufacturer. In order to achieve interoperability, control valves produced by different manufacturers should be able to be used in conjunction with products produced by other manufacturers without signal imbalance and impedance imbalance.
Standard diagnostic software and auxiliary software can enable control valves of different manufacturers to perform working status diagnosis and working data analysis. The selection of the regulator has always been a problem that the automatic control designer is very concerned about. Through the standardized calculation program, the flow coefficient of the required regulator can be accurately calculated according to the data provided by the process, the piping and the selection of the appropriate regulator body can be accurately calculated , Valve core and inner materials, standardize the design process and improve design quality.
3. Energy saving:
Reducing energy consumption and improving energy utilization are the development direction of control valves. The pressure regulating valve adopts a low pressure drop ratio, which reduces the pressure drop ratio of the entire system, thereby reducing energy consumption. Therefore, designing a pressure regulating valve with a low pressure drop ratio is one of the development directions; in addition, a low impedance pressure regulating valve, such as a butterfly valve, Eccentric rotary valve, etc.
