The development history of solenoid valves With the wider application of solenoid valves and the higher requirements for solenoid valves, more and more refined and stricter solenoid valves have been derived. The development process of solenoid valves is always accompanied by the market. The pace of follow-up is mainly due to the sharp increase in the demand for various special solenoid valves. The following are introduced by media category:
(1) Solenoid valve for water
Solenoid valves for water are always considered to be the simplest. In fact, water is divided into tap water, industrial pure water, industrial wastewater, irrigation water, seawater and other categories. Its corrosive properties and cleanliness are different. Different electromagnetic valves should be selected respectively. valve. Although the tap water valve is the most common, the performance requirements of the valve are different for different uses.
For example, the reliability of the action of the solenoid valve for fire protection is very important, and the consequences in case of failure will be disastrous. Even if the ordinary manual valve is not opened and closed for a long time, it is difficult to open it quickly. In recent years, high-rise buildings have sprung up, and China's fire solenoid valve technology has also matured. Another example is that the water plant needs to use the solenoid valve for the inverted siphon pipeline. This solenoid valve must work reliably under the pressure state and in the vacuum state, and there must be no internal leakage, and the cleanliness of the water is not high. down, still should be flexible. In addition, the sprinkler solenoid valve has also been gradually applied with the development of China's agriculture and gardening industry.
(2) Steam solenoid valve
The steam solenoid valve must first solve the problem of high temperature resistance, and its sealing materials, conductive and magnetic conductive materials must be specially selected. The corrosion of steam pipes is relatively severe and must be taken seriously. More importantly, there is a lot of condensed water in the steam pipeline after get off work in the factory. The solenoid valve needs to be able to operate reliably when gaseous and liquid fluids pass through. There are many strict procedures for its factory inspection.
(3) The gas solenoid valve is accompanied by the demand of the new market and the continuous improvement of the development of the social economy. The competition in various industries is also becoming increasingly fierce. The new market continues to promote the wider application range of the solenoid valve. The performance, quality, reliability and service of the solenoid valve are all available. Great improvement. The solenoid valve industry is developing in the direction of high automation, intelligence, multi-function, high efficiency and low consumption, and it has become a necessary product in the production process of many industries.
The development of the 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 because of its cheap, simple, fast action, easy installation and easy maintenance. From the 1950s to the 1980s, it had been reliant on imports. It was not until the 1990s that domestic solenoid valves occupied a certain market share.
The strong market demand for solenoid valve products benefits from these aspects. The sustained and stable development of the state-owned economy and the gradual expansion of investment in fixed assets, especially the start of several century projects such as "West-East Gas Transmission", "West-East Electricity Transmission", "South-to-North Water Diversion" and other projects require a large number of valve products; Facing the arrival of the industrialization era, the petrochemical industry, power sector, metallurgical sector, chemical industry and urban construction and other large valve users will increase the demand for solenoid valve products.
Continuous promotion of new materials
my country's natural resources are limited, and formulating standards for energy saving, water saving, and material saving is one of the development directions of solenoid valve standards. Accelerate the elimination of products with low efficiency and high energy consumption, adjust the industrial structure, and promote the development, promotion and application of new technologies and new products.
In terms of reducing energy consumption, vigorously develop valve products with small flow resistance and low loss. In terms of power saving, the focus is on the electric device of the solenoid valve. By selecting a motor with low energy consumption and low noise, and improving the structure of the electric device, the energy consumption of the electric device is controlled.
The raw materials for making ceramics are extensive and the cost is low. Common elements such as aluminum, carbon, and silicon can be used to manufacture ceramic materials with superior performance, which can save a lot of metal materials and rare mineral resources. Ceramic valves are used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields. They have wear resistance and good sealing performance, which can minimize leakage and play a positive role in promoting environmental protection. Keeping up with the development of technology, the Valve Standards Committee organized and formulated the "Ceramic Sealed Valve" standard to accelerate the promotion of ceramic sealing technology and promote the development of ceramic sealing materials.
In terms of material saving of solenoid valves, the focus is on researching new materials and replacing metal materials with new materials 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 prolongs the service life of the valve.
Industry insiders analyzed that solenoid valve enterprises should also strengthen the connection between standards and scientific research, especially the research of major national science and technology projects, guide scientific research and technologically advanced backbone enterprises, convert the results of independent innovation into standards, and promote the development of new technologies and new processes . The formulation of the high-tech standard "Valve Intelligent Electric Device" has a great effect on promoting the development of the industry and blocking or reducing imported products.
At the same time, a batch of new products and new technologies were transformed into standards, which reduced costs, improved benefits, optimized the function of solenoid valve products, and made new products and new technologies quickly recognized by the building materials market, promoting industrial progress.
