    With the various needs of modern life, then the production of these important products of spare parts are endless Below we list the main application fields of these 10 categories of valves 1 Valves for petroleum units; 1) most of the valves for oil refining units are pipeline valves, mainly including gate valve, globe valve, check valve, safety valve, ball valve, butterfly valve and drain valve, of which the demand for gate valve accounts for about 80% of the total number of valves (3% to 5% of the total installation investment); 2) chemical fiber device, chemical fiber products mainly include polyester, acrylic and vinylon The ball valve and jacketed valve (jacketed ball valve, jacketed gate valve and jacketed stop valve) of the required valve; 3) propylene clear device Generally, the unit needs valves of standard production, mainly including gate valve, stop valve, check valve, ball valve, drain valve, needle stop valve, plug valve, among which gate valve accounts for about 75% of the total valve; 4) synthetic ammonia unit Because of the different synthetic ammonia and purification methods, the process flow is different, and the technical functions of the required valves are also different At present, gate valve, stop valve, check valve, drain valve, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high-temperature and low-temperature valve are mainly used in domestic ammonia plant; 2 Application valve of hydropower station The construction of power stations in China is developing towards large-scale development, so large-diameter and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency block valves and flow control valves, globe sealed instrument stop valves are needed (according to the national "Tenth Five Year Plan", in addition to Inner Mongolia and Guizhou, more than 200000 kilowatt units can be built in other provinces and cities, only 300000 kilowatt units can be built in other provinces and cities Third, the alumina behavior in metallurgical industry mainly needs wear-resistant slurry valve (in flow stop valve) and regulating drain valve The steel-making industry mainly needs metal sealed ball valve, butterfly valve and oxidation ball valve, cut-off flash valve and four-way reversing valve; fourthly, with the development of offshore oil field exploitation, the number of valves required for offshore flat development is also increasing The offshore platform needs shut-off ball valve, check valve and multi-way valve; V food and pharmaceutical application valve, the industry mainly needs stainless steel ball valve, non-toxic all plastic ball valve and butterfly valve Among the above 10 categories of valve products, the demand for general valve is more, such as instrument valve, needle valve, needle stop valve, gate valve, stop valve, check valve, ball valve and butterfly valve; VI the rural and urban construction application valves and urban construction systems generally use low-pressure valve, which is currently developing in the direction of environmental protection and energy conservation Environmental friendly rubber plate valve, balance valve, middle line butterfly valve and metal seal butterfly valve are gradually replacing low-pressure iron gate valve Most of the valves required for urban buildings in China are balance valve, soft seal gate valve, butterfly valve, etc.; VII In rural and urban heating valves and urban heating system, a large number of metal seal butterfly valve, horizontal balance valve and direct buried ball valve are required to solve the problem of vertical and horizontal hydraulic imbalance of pipeline, so as to achieve the purpose of energy conservation and heat balance generation VIII In the environmental protection application valve and domestic environmental protection system, the water supply system mainly needs center line butterfly valve, soft seal gate valve, ball valve and exhaust valve (used to remove the air in the pipeline) The sewage treatment system mainly needs soft sealing gate valve and butterfly valve; 9 The valves for gas and urban gas account for 22% of the whole natural market, with large valve consumption and many types It mainly needs ball valve, plug valve, pressure reducing valve and safety valve; X pipeline application valve and long-distance pipeline are mainly crude oil, finished product and natural pipeline Most of these valves are forged steel three body full bore ball valve, sulfur resistant flat gate valve, safety valve and check valve.
