The development of solenoid valve market cannot be separated from new technology and new technology

Wide application of solenoid valve and large market space

As one of the actuators of fluid control automation system, solenoid valve has become the product of fluid control automation because of its cheap, simple, fast action, easy installation and maintenance. In the 1950s-1980s, China has been relying on advanced technology, until the 1990s, the domestic solenoid valve occupied a certain market share.

The strong market demand of solenoid valve products benefits from these aspects. The steady development of state-owned economy and the gradual expansion of investment in fixed assets, especially the start-up of several century projects such as "west to East Gas Transmission", "west to East power transmission" and "south to North Water Diversion" require a large number of valve products; In addition, China is facing the arrival of the era of industrialization, petrochemical industry, power sector, metallurgical sector, chemical industry and urban construction and other valve users will increase the demand for solenoid valve products. During the "Eleventh Five Year Plan" period, the total demand of valves for large and medium-sized coal-fired generating units in the power industry is 153000 tons, with an average annual demand of 30600 tons; The total demand for valves is 3.96 billion yuan, with an average annual demand of 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 265600 tons, the average annual demand is 53200 tons, the total demand for valves is 6.64 billion yuan, and the average annual demand is 1.328 billion yuan.

Developing new materials to promote industrial transformation

Due to the limited natural resources in China, one of the development directions of solenoid valve standard is to formulate the standards of electricity saving, water saving and material saving. Speed up 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 products.

In terms of reducing energy consumption, vigorously develop valve products with small flow resistance and loss. In terms of power saving, the focus is on the electric device of solenoid valve. Through the selection of low energy consumption and low noise motor and the improvement of the structure of the electric device, the energy consumption of the electric device can be controlled.

Ceramic materials are widely used with low cost. Ceramic materials with superior performance can be made by using common elements such as aluminum, carbon and silicon, which can save a lot of metal materials and rare mineral resources. Ceramic valve is used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields. It has good wear resistance, good sealing performance, and can minimize leakage, which will play a positive role in promoting environmental protection. Following the development of technology, the valve Standard Committee organized and formulated the standard of "ceramic sealing valve", which accelerated the promotion of ceramic sealing technology and promoted the development of ceramic sealing materials.

In the aspect of material saving of solenoid valve, the key point is to study new materials and replace metal materials with new materials, so as to achieve the purpose of saving steel and precious metals. The new ceramic valve uses new ceramic materials to make the sealing parts and vulnerable parts of the valve, which improves the wear resistance, corrosion resistance and sealing performance of the valve products, and greatly extends the service life of the valve.

Promote the development of new technology and process

We should strengthen the connection between standards and scientific research, especially the research on major national scientific and technological projects, guide key enterprises in scientific research and technology, transform the achievements of independent innovation into standards, and promote the development of new technologies and processes. For example, Yangzhou electric power repair and construction, Tianjin Ertong, Wenzhou rotok, Changzhou power station auxiliary equipment can be produced, and the product quality is also quite good. The development of high-tech "valve intelligent electric device" standard plays an important role in promoting the development of the industry and blocking or reducing the import of products.

A batch of new products and technologies are transformed into standards, which reduces the cost, improves the efficiency, optimizes the function of solenoid valve products, and makes the new products and technologies quickly recognized by the building materials market, and promotes the progress of the industry.
