Information
Liaoning Valve has been used by humans for nearly 4,000 years. In ancient China, when brine was used to make salt from salt wells, wooden plug valves were used in bamboo pipelines. In 1800 BC, when the ancient Egyptians built large-scale water conservancy to prevent the Nile from flooding, they used similar wooden cock to control the distribution of water flow. These are the prototypes of the valve. The large number of applications of industrial valves began after Watt invented the steam engine. In the early twentieth century, valves made of cast iron, cast steel, forged steel, stainless steel, chromium molybdenum steel, brass and other materials appeared. Used in various industries and various working conditions. There are not many companies that first introduced foreign valve production technology in China. Later, the introduction of foreign production technology has made breakthroughs in domestic valve production technology, improved quality, and extended life.
The valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa ultra-high pressure and working temperature From the ultra-low temperature of -269℃ to the high temperature of 1430℃. The valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc.; it can be driven by pressure and temperature. Under the action of other forms of sensing signals, it will act according to the predetermined requirements, or simply open or close without relying on the sensing signals. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate Movement, thereby changing the size of the flow channel area to achieve its control function.
With the acceleration of the restructuring of the valve industry, the future industry will be a competition between valve product quality and safety and product brands. Products will develop in the direction of high technology, high parameters, strong corrosion resistance and long life. Only through continuous technological innovation, development For new products, technological transformation can gradually improve the technical level of products, meet the needs of domestic equipment, and fully realize the localization of valves. Under the huge demand environment of my country's valve manufacturing industry, it is bound to show better development prospects. Liaoning Valve
