The market price of stainless steel valves is 10 yuan to 520 yuan. (Price source network, for reference only. )
Main uses of stainless steel valves
Stainless steel valves are widely used in chemical industry, petrochemical industry, petroleum, paper making, mining, electric power, liquefied gas, food, pharmacy, water supply and drainage, municipal administration, mechanical equipment, electronic industry, urban construction and other fields. Valve is a control part in the pipeline fluid transportation system, which is used to change the cross section of the channel and the flow direction of the medium, and has the functions of shunting, cutoff, adjustment, throttling, check, shunting or overflow pressure relief. Valves used for fluid control range from the simplest shut-off valve to various valves used in extremely complicated automatic control systems. Stainless steel valves can be used to control the flow of water, steam, oil, gas, mud, various corrosive media and various types of fluids such as liquid metal and radioactive fluids? The working pressure of the valve ranges from 0.00 13MPa to 1000MPa? Ultra-high pressure, working temperature from ultra-low temperature of -269℃ to high temperature of 1430℃.
Application scope of stainless steel valve
Stainless steel valves are usually used in corrosive working media. The corrosion resistance of any valve material is relatively limited and is influenced by many factors. If the processing technology and heat treatment technology used in the manufacturing process are appropriate, the corrosion resistance of this material can be guaranteed. As for concentration >: in 98% concentrated nitric acid medium, this steel has no corrosion resistance no matter what heat treatment process is adopted. Therefore, when selecting the valve material according to the nature of the working medium, we must also study the influence of the concentration of the medium, temperature and heat treatment process of the material on the corrosion resistance. Stainless steel valves have become the valve products that all industries must purchase, but few valve manufacturers in China can meet the international standards. Therefore, before purchasing stainless steel valves, customers must ask merchants to provide production and factory certificates of various stainless steel valves, which can reduce the number of unqualified products.
At present, stainless steel valves and sanitary valves meet international standards mainly from Japan, Germany, the United States, Britain and China's first tier cities. Stainless steel valve is the control element in the pipeline fluid transportation system, which is used to change the cross section of the channel and the flow direction of the medium, and has the functions of diversion, cutoff, adjustment, throttling, check, diversion or overflow pressure relief. ? Valves used for fluid control range from the simplest shut-off valve to various valves used in extremely complicated automatic control systems. Valves can be used to control water, steam, oil, gas, mud and various corrosive media. The control of the valve can adopt various transmission modes. For example, manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic-hydraulic, electric-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc. Under the action of pressure, temperature or other forms of sensing signals, it acts according to predetermined requirements, or simply opens or closes without relying on sensing signals. Valves rely on driving or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate. So as to change the size of its flow channel area and realize its control function.
The above small series introduces the price of stainless steel valves, the industries in which stainless steel valves can be applied and the characteristics of stainless steel valves. After reading the above, will everyone marvel at the super adaptability of stainless steel valves? Stainless steel valves can withstand corrosive liquids and ultra-high temperature liquid metals, so they are very marketable valves. The price range of stainless steel valves in the market is quite large. If you need to buy them, you should do your homework.
