Summary: a, stainless steel valve stainless steel valves, as the name implies, is made of stainless steel valves. Stainless steel valve material quality, in turn, strengthen, generally speaking, there are 304 stainless steel, 304 l stainless steel, 316 stainless steel, 316 l stainless steel and two-way stainless steel. Use stainless steel valve industry: food biscuits industries, instant noodles and rice noodles, a variety of quick-frozen food dehydration assembly line equipment, glass products industry. Can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. Stainless steel valves are widely used in chemical, petrochemical, petroleum, the papermaking, mining, electricity, liquid gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields. Stainless steel valve is control unit in the pipeline fluid conveying system, it is used to change the channel cross-section and flow direction of medium, a diversion, globe, regulation, throttle, check, or the overflow pressure relief, and other functions. Used for fluid control valve, from the most simple cut-off valve to extremely complex automatic control system used in all kinds of valves, its various varieties and specifications. Stainless steel valves can be used to control water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, pressure valve operation can be from 0. Ultra-high pressure 0013 mpa to 1000 mpa, from operating temperature Ultra-low temperature of 269 ℃ to 1430 ℃ high temperature. Stainless steel valves are normally used in the working medium has certain corrosion occasion. Any kind of valve with material, working medium corrosion resistant ability is relatively limited, and affected by many factors. If used in the process of manufacturing process and proper heat treatment process, ensuring that the corrosion resistance of the material. As for the concentration & gt; 98% nitric acid medium, no matter adopt what kind of heat treatment process, this kind of steel with corrosion resistance. Therefore, in selecting the valve material according to the nature of the working medium, must study the concentration of the medium at the same time, temperature and material heat treatment process of the influence of various factors on the corrosion resistance. Stainless steel valves has become the industry will be purchasing in the field of valve products, the domestic only a few can reach the international standard of the valve manufacturer, so customers before purchasing stainless steel valves must ask vendors to provide all kinds of stainless steel valve production and factory certificate, thus reducing the unqualified products. Now stainless steel valves and sanitary valves reach international standard valves come mainly from Japan, Germany, the United States, Britain, and domestic first-tier cities of Shanghai. Stainless steel Industrial Valves valve is control unit in the pipeline fluid conveying system, it is used to change the channel cross-section and flow direction of medium, a diversion, globe, adjust, throttle, check, or the overflow pressure relief, and other functions. Used for fluid control valve, from the most simple cut-off valve to extremely complex automatic control system used in all kinds of valves, its various varieties and specifications. The valve can be used to control water, steam, oil, gas, mud, all kinds of corrosive medium. control can use a variety of transmission way, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic actuator, electromagnetic, hydraulic, electric, hydraulic, pneumatic, hydraulic, spur gear, bevel gear drive, etc. ; In pressure, temperature or other form under the action of sensor signals, action, according to the requirement of the reservation or not depend on the sensor signals for simple open or shut down, rely on the drive or automatic mechanism makes opening and closing valve for lifting, sliding, place or rotary movement, so as to change the size of the port in order to realize the control function. Second, the classification of stainless steel valves stainless steel valves according to the most versatile can be divided into the following kinds: 1, stainless steel butterfly valve, such as stainless steel stainless steel electric butterfly valve stainless steel manual butterfly valve pneumatic butterfly valve, stainless steel ball valves, such as stainless steel stainless steel ball valve pneumatic ball valve flange ball valve spool valves stainless steel stainless steel stainless steel stainless steel ball valve of cutting sleeve type has the thermal insulation ball valve, stainless steel gate valve: gate valves such as stainless steel stainless steel flange valve stainless steel insulation gate valve stainless steel high-pressure gate 4, stainless steel check valve: such as stainless steel stainless steel check valve swing check valve lift check valve stainless steel wafer check valve stainless steel swing check valves, stainless steel valve: such as stainless steel bevel gear cut-off valve hydraulic valve stainless steel stainless steel male cut-off valve stainless steel female cut-off valve stainless steel flange valve, stainless steel ball valve: this article by ( All standing valve technology) Editing and publishing
