Solenoid valve application broad market space

As one of the actuators of the fluid control automation system, the solenoid valve has become the first choice for fluid control automation due to its features of low cost, simplicity, quick movement, easy installation, and easy maintenance. In the 50s and 80s of the 20th century, it had been relying on imports. Until the 1990s, domestic electromagnetic valves took up a certain market share.

The strong demand for the solenoid valve product market has benefited from these aspects. The sustained and steady development of the state-owned economy and the gradual expansion of investment in fixed assets, especially for the start-up of projects such as West-to-East Gas Transmission, West-to-East Electricity Transmission, and South-to-North Water Transfer Project for a few centuries, require a large number of valve products; Faced with the advent of the era of industrialization, the use of large valve manufacturers in the petrochemical industry, the power sector, the metallurgy sector, the chemical industry, and the urban construction will increase the demand for solenoid valve products. In the “Eleventh Five-Year Plan” period, the total number of valves required for large and medium-sized coal-fired power plant start-up projects during the “11th Five-Year Plan” period is: Total valve demand is 153,000 tons, annual average demand is 30,600 tons; total valve demand is 3.96 billion yuan, annual average Demand is 792 million yuan. According to the average annual growth rate of 20%, the total demand for valves during the “12th Five-Year Plan” period is 265,600 tons, the average annual demand is 53,200 tons, the total valve demand is 6.64 billion yuan, and the average annual demand is 13.28. 100 million yuan.

Develop new materials to promote industrial transformation

China's limited natural resources, the development of energy-saving, water-saving, material-saving standards is one of the development direction of the solenoid valve standard. 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 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 electromechanical device of the solenoid valve. By selecting a low-energy and low-noise motor and improving the structure of the electric device, the energy consumption of the electric device is controlled.

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" standard, accelerated the promotion of ceramic sealing technology, and promoted the development of ceramic sealing materials.

For solenoid valve materials, the focus is on researching new types of materials and using new materials instead of metal materials 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.

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 the development of new technologies and new processes. 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 solenoid valves have been optimized, and new products and new technologies have been rapidly recognized by the building materials market, which has promoted the progress of the industry.
