The Most Common Application Areas Of Valves

With the various needs of modern life, the spare parts for producing these important products are also emerging in an endless stream. Below we list the main application areas of these 10 categories of Lined Valve. 1: Valves for petroleum equipment; 1》Oil refining equipment. Most of the valves required for oil refining equipment are pipeline valves, mainly gate valves, stop valves, check valves, safety valves, ball valves, butterfly valves, steam traps, among which the demand for gate valves accounts for about 80% of the total number of valves (valves account for 3% to 5% of the total investment of the equipment); 2》Chemical fiber equipment. Chemical fiber products mainly include polyester, acrylic, and vinylon. The valves required are ball valves and jacketed valves (jacketed ball valves, jacketed gate valves, jacketed stop valves); 3》Acrylonitrile equipment. The equipment generally requires standard-produced valves, mainly gate valves, stop valves, check valves, ball valves, steam traps, needle stop valves, and plug valves. Among them, gate valves account for about 75% of the total number of valves; 4》Ammonia synthesis equipment. Because the synthesis of ammonia and purification methods are different, the process flow is different, and the technical functions of the required valves are also different. At present, domestic ammonia synthesis devices mainly need gate valves, stop valves, check valves, steam traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high-temperature and low-temperature valves; 2: Valves for hydropower stations: The construction of power stations in my country is developing in the direction of large-scale development, so large-caliber and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency shut-off valves and flow control valves, spherical sealing instrument stop valves are required (according to the national "15th Five-Year Plan", except for Inner Mongolia and Guizhou provinces, which can build units above 200,000 kilowatts, other provinces and cities can only build units above 300,000 kilowatts); 3: Valves for metallurgical applications: Alumina in the metallurgical industry mainly requires wear-resistant slurry valves (in-flow stop valves) and regulating steam traps. The steelmaking industry mainly needs metal-sealed ball valves, butterfly valves and oxidation ball valves, stop valves and four-way reversing valves;

4: Marine application valves: With the development of offshore oil field exploitation, the amount of valves required for offshore platforms is gradually increasing. Offshore platforms require shut-off ball valves, check valves, and multi-way valves;

5: Food and medicine application valves: This industry mainly needs stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves. Among the above 10 major categories of valve products, the demand for general valves is relatively large, such as instrument valves, needle valves, needle stop valves, gate valves, stop valves, check valves, ball valves, and butterfly valves;

6: Rural and urban construction application valves: Urban construction systems generally use low-pressure valves, and are currently developing in the direction of environmental protection and energy saving. Environmentally friendly rubber plate valves, balancing valves, center line butterfly valves, and metal-sealed butterfly valves are gradually replacing low-pressure iron gate valves. Most of the valves required for domestic urban buildings are balancing valves, soft-sealed gate valves, butterfly valves, etc.;
7: Valves for rural and urban heating: In urban heat generation systems, a large number of metal-sealed butterfly valves, horizontal balancing valves and directly buried ball valves are required, because these valves solve the problem of longitudinal and lateral hydraulic imbalance in pipelines to achieve energy saving and heat generation balance.
8: Valves for environmental protection applications: In domestic environmental protection systems, the water supply system mainly requires center-line butterfly valves, soft-sealed gate valves, ball valves, and exhaust valves (used to remove air from the pipeline). Sewage treatment systems mainly require soft-sealed gate valves and butterfly valves;
9: Valves for gas: Urban gas accounts for 22% of the entire natural gas market, and the valve consumption is large, and its types are also many. Mainly ball valves, plug valves, pressure reducing valves, and safety valves are required;
10: Valves for pipeline applications: Long-distance pipelines are mainly crude oil, finished products, and natural gas pipelines. The valves that are mostly required for this type of pipeline are forged steel three-body full-diameter ball valves, sulfur-resistant flat gate valves, safety valves, and check valves.
