The national valve standard committee is now formulating the national standard "valve intelligent electric device." Valve intelligent electric device is a new type of product developed abroad at the beginning of this century. China has mastered this technology through introduction and R&D, and it has developed very fast.
Valves are products with low profit margins and the market is highly competitive. The distribution of the valve market is mainly based on the construction of the project. The largest users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. The petrochemical industry mainly uses gate valves, globe valves and check valves of API standards; the power sector mainly adopts low-pressure butterfly valves and gate valves for power station high-temperature pressure gate valves, globe valves, check valves, and safety valves and some of the water supply and drainage valves; the chemical industry mainly adopts them. Stainless steel gate valve, globe valve and check valve; the metallurgical industry mainly uses low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve; the urban construction department mainly adopts low-pressure valves, such as urban tap water pipelines mainly adopt large-diameter gate valves, and Louyu construction adopts the middle line. The butterfly valve, the city heating mainly uses the metal seal butterfly valve; The oil pipeline mainly uses the flat gate valve and the ball valve; The pharmaceutical industry mainly uses the stainless steel ball valve; The food industry mainly uses the stainless steel ball valve and so on. The valve is used in a large amount in the water treatment industry, mainly in low pressure valve products such as butterfly valves, gate valves, and check valves. It is understood that there are more than 2,000 valve companies with a certain scale on the market, most of which are located in Jiangsu, Zhejiang and Central Plains. Due to the relatively low technical content of products, the competition is even fiercer.
Against such a backdrop, China's valve can only take a good place in its fierce market competition by grasping its own development context, taking the path of independent innovation and independent research and development, and promoting the adjustment of its industrial structure.
1. Promote the development of new technologies and new processes Strengthen the links between standards and scientific research, especially the research of major national science and technology projects, guide leading enterprises with advanced scientific research and technology, translate the results of independent innovation into standards, and promote new technologies and processes. development of. For example, Yangzhou Power Construction, Tianjin Ertong, Wenzhou Rotork, and Changzhou Power Station auxiliary equipment can all be produced, and the product quality is also quite good. The formulation of high-tech standards for "valve intelligent electric devices" has a great effect on promoting the development of industries and blocking or reducing imported products.
By converting a batch of new products and new technologies into standards, the cost has been reduced, the benefits have been improved, the functions of the products have been optimized, new products and new technologies have been quickly recognized by the market, and industrial progress has been promoted.
2. Development of standards for energy conservation, consumption reduction, new materials, etc., and promotion of industrial restructuring China's natural resources are limited. Therefore, the development of energy-saving, water-saving, and material-saving standards is one of the directions for the development of valve standards. Accelerate the elimination of products with low efficiency and high energy consumption, adjust the industrial structure, and promote the development and application of new technologies and new products.
In the aspect of material saving, the focus of the valve is on researching new-type materials and replacing new metal materials with new ones to save steel and precious metals.
The new ceramic valve adopts a new type of ceramic material to make the sealing and wearing parts of the valve, which improves the wear resistance, corrosion resistance and sealing performance of the valve product, and greatly prolongs the service life of the valve.
The raw materials for the manufacture of ceramics are extensive, and the cost is low. The use of common elements such as aluminum, carbon, and silicon can produce superior ceramic materials, which can save a large amount of metallic materials and rare mineral resources. Ceramic valves are used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields. They are wear-resistant, have good sealing, can minimize leakage, and will play an active role in promoting environmental protection. Following the development of technology, the Valve Standardization Committee organized the "Ceramic Sealed Valve" (JB/T10925-2005) standard to accelerate the promotion of ceramic sealing technology and promote the development of ceramic sealing materials.
In terms of reducing energy consumption, we will vigorously develop valve products with small flow resistance and low loss. In terms of power saving, the focus is on the electric devices of the valves. By selecting low-power and low-noise motors and improving the structure of the electric devices, the energy consumption of the electric devices is controlled.
