10 major categories of valves main areas of application

With the various needs of modern life, then the production of spare parts for these important products is also endless. Below we list the main application areas of these 10 categories of valves.

1, stone by the device with the valve;

(1) oil refining unit, oil refining unit requires most of the valves are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, of which, the gate valve needs to account for the total number of valves about 80%, (valves accounted for the total investment in the device 3% to 5%);

(2) chemical fiber device, chemical fiber products are mainly polyester, acrylic, polyvinyl chloride three categories. Its need for valves of ball valves, jacketed valves (jacketed ball valves, jacketed gate valves, jacketed globe valves);

(3) acrylic acrylic device. The device generally need to use the scale out of the valves, mainly gate valves, globe valves, check valves, ball valves, traps, needle globe valves, plug valves, of which, gate valves accounted for about 75% of the total number of valves;

(4) ammonia plant. Because of the synthesis of ammonia and purification methods are different, the process is different, the technical function of the required valves are also different. At present, the domestic ammonia plant mainly requires gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high temperature and low temperature valves;

2, hydropower station application valves, China's power plant construction is developing in the direction of large-scale, so the need for large-diameter and high-pressure safety valves, pressure-reducing valves, globe valves, gate valves, butterfly valves, emergency blocking valves and flow control valves, spherical seal instrumentation globe valves, (according to the national “Tenth Five-Year Plan”, in addition to Inner Mongolia, Guizhou Province, but also can be built in the provinces of 200,000 kilowatts) (According to the national “Tenth Five-Year Plan”, in addition to Inner Mongolia, Guizhou provinces can also build 200,000 kilowatts or more units, other provinces and cities can only build more than 300,000 kilowatts);

3, metallurgical applications valves, metallurgical industry, alumina behavior is mainly required to wear-resistant slurry valve (in the flow of stop valve), regulating traps. Steelmaking industry mainly requires metal-sealed ball valves, butterfly valves and oxidation ball valves, cut-off flash and four-way directional valves;

4, marine applications valves, followed by the development of offshore oilfield mining, the amount of its marine Pingfa need to use the valve has gradually increased. Marine platforms require shut-off ball valves, check valves, multi-way valves;

5, food and medicine application valves, the industry mainly requires stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves. The above 10 major categories of valve products, the demand for general-purpose valves compared to the majority, such as instrumentation valves, needle valves, needle globe valves, gate valves, globe valves, check valves, ball valves, butterfly valves mostly;

6, the countryside, urban construction applications valves, urban construction system with the general use of low-pressure valves, is currently being developed in the direction of environmentally friendly and energy-saving. Environmentally friendly rubber plate valve, balance valve and centerline butterfly valve, metal-sealed butterfly valve is gradually replacing the low-pressure iron gate valve. The sea of urban buildings need to use the valve is mostly balance valve, soft seal gate valve, butterfly valve;

7, the countryside, urban heating valves, urban heating system, need to use a large number of metal-sealed butterfly valves, horizontal balancing valves and directly buried ball valves, because these valves to solve the pipeline longitudinal, horizontal hydraulic disorders, to achieve energy saving, generation of heat balance.

8, environmental protection applications valves, environmental protection systems in the sea, the water supply system is mainly required to use the center line butterfly valves, soft sealing gate valves, ball valves, exhaust valves (used to exclude the air in the pipeline). Sewage treatment system mainly need to use soft seal gate valve, butterfly valve;

9, gas valves, city gas accounted for the entire natural full market of 22%, the valve dosage, its type is also more. Mainly need ball valves, plug valves, pressure reducing valves, safety valves;

10, pipeline application valves, long-distance pipeline mainly for crude oil, finished products did not and natural pipelines. This type of pipeline needs to use most of the valves are forged steel three-body full bore ball valves, anti-sulfur plate gate valves, safety valves, check valve
