Analysis of the main application fields of ten kinds of valve industry
With the variety of the need of modern life, so the production of spare parts of these important products also emerge in an endless stream. We list below the application field of the 10 major categories of main valve. 1: stone by the device
With the variety of the need of modern life, so the production of spare parts of these important products also emerge in an endless stream. We list below the application field of the 10 major categories of main valve.
1: stone by the device for valve;
1 "refinery, oil refining device with valve mostly pipe valves, mainly valve, globe valve, check valve,safety valve, ball valve, butterfly valve, drain valve, wherein, the valve to be accounted for about80% of the total (valve, valve accounted for a total investment of 3% to 5% devices);
2 "chemical equipment, chemical products are polyester, acrylic, PVA three categories. Ball valve,the required valve jacketed valve (jacket ball valve, gate valve, the jacket jacketed valve);
3 "acrylonitrile apparatus. The device is generally required scale production of valves, mainly valve,globe valve, check valve, ball valve, drain valve, needle valve, plug valve, which valve, gate valveaccounted for about 75% of the total;
4 "synthetic ammonia device. Because the original ammonia and purification methods different, the process is different, the technical functions required for the valve is also different. At present, need to use the main gate valve, globe valve domestic ammonia plant, check valve, butterfly valve, ball valve, drain valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature valves;
2: the application of valve hydropower station: China power station construction forward direction of large-scale development, so need to use large diameter and high pressure safety valve, pressure reducing valve, globe valve, gate valve, butterfly valve, emergency cut off valve and a flow control valve, a spherical sealing instrument valve, (according to the national "fifteen" plan, in addition to Inner Mongolia, Guizhou two also can be built more than 200000 kilowatts unit, other provinces and cities can only be built units 300000 kilowatts and above);
3: application in metallurgy valves: Metallurgical alumina industry need to use the main abrasion resistant slurry valve (in flow valve), adjust the trap. Steel industry is mainly required metal sealing ball valve, butterfly valve, ball valve and oxidation as flash and four way reversing valve;
4: marine application valve: with the development of offshore oil exploitation, the marine valve required amount gradually increased. Offshore required off valve, check valve, multi way valve;
5: Food and medicine application of valve: the main industry needed stainless steel ball valve, non-toxic plastic ball valve and butterfly valve. The above 10 categories in general valve valve products,compared with the demand of the majority, such as instrumentation valve, needle valve, needle valve, gate valve, globe valve, check valve, ball valve, butterfly valve majority;
6: the valve application in village, city building: urban construction system generally use low pressure valves, are currently being environmentally friendly and energy-saving direction.Environment friendly plastic sheet valve, balance valve and the center line butterfly valve, metal sealed butterfly valve is gradually replaced by low iron gate. Domestic city construction with the valve more than the balance valve, soft seal gate valve, butterfly valve;
7: the village, city heating valve: City on behalf of the thermal system, which requires large amounts of metal sealing butterfly valve, balance valve and the level of direct buried ball valve, valve solution for this type of pipeline vertical, horizontal hydraulic imbalance problem, to achieve energy saving,on behalf of the heat balance purposes.
8: the application of environmental protection valve: the domestic environmental protection system,the main use the center line butterfly valve, soft seal gate valve, ball valve, water supply system, the exhaust valve (used to exclude the air pipe). Sewage disposal system is mainly required soft sealing gate valve, butterfly valve;
9: the gas valves: City gas accounted for the entire natural all 22% of the market, a large amount of the valve, its type is also more. The main ball valve, plug valve, need the pressure reducing valve,safety valve;
10: pipeline application of valve: long-distance pipeline is mainly crude oil, finished no and naturalpipeline. The majority of such amount to the pipeline valve is a three body forged steel full bore ball valve, anti sulfur flat gate valve, safety valve, check valve.
