Check Valve Refinery equipment required
With the needs of modern life, then the production of these important products, spare parts are endless. Here we list the main application areas of these 10 categories of valves.
1) oil refineries, oil refueling devices need to use the valve are mostly pipeline valves, mainly for the gate valve, check valve, check valve, safety valve, ball valve, butterfly valve, trap, which accounted for valve accounted for about 80% of the total number of valves, (Valves account for 3% to 5% of total investment);
2) chemical fiber device, chemical fiber products are polyester, acrylic, vinylon three categories. Its need to use the valve ball valve, jacket valve (jacket ball valve, jacket gate valve, jacket cut valve);
3) acryl clear device. The device is generally required to produce the valve scale, mainly for the gate valve, globe valve, check valve, ball valve, trap, needle valve, plug valve, which accounted for about 75% of the total valve;
4) ammonia plant. Because the synthesis of ammonia and purification methods are different, the process is different, the required technical function of the valve is also different. At present, the domestic ammonia plant mainly need gate valve, globe valve, check valve, trap, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature and low temperature valve;
2, the application of hydropower stations, China's power plant construction is the direction of large-scale development, so the need for large diameter and high pressure safety valve, pressure relief valve, globe valve, gate valve, butterfly valve, emergency shut-off valve and flow control valve, spherical sealing instrument (According to the national "15" plan, in addition to Inner Mongolia, Guizhou provinces can also build more than 200,000 kilowatts of units, other provinces and cities can only build more than 300,000 kilowatts of units);
3, metallurgical application of the valve, metallurgical industry, the main need for wear-resistant slurry valve (in the flow cut-off valve), adjust the trap. Steel industry mainly need to use metal sealed ball valve, butterfly valve and oxidation ball valve, cut off the flash and the four-way valve;
4, marine application of the valve, along with the development of offshore oilfield development, the need for the development of the ocean level of the valve is also increasing. Offshore platform need to turn off the ball valve, check valve, multi - valve;
