The future development and application of electric butterfly valve are mainly reflected in the following aspects: Dongfeng electric butterfly valve
1. The transportation market, including the provision of supporting and maintenance parts butterfly valves for automobile, motorcycle, diesel engine, railway and other industries, is an important and promising market in the butterfly valve industry at present, with sales close to 40% of the whole industry. In 2002, the demand for suspension butterfly valves in the automobile industry alone was 7 million, 100 million valve butterfly valves (including motorcycle and diesel engine manufacturing), and 1.2 million stabilizer bars.
2. Daily use goods and hardware industries such as lighters, toys, locks, door hinges, fitness machines, mattresses, sofas, etc., in terms of quantity, demand for butterfly valves is large, tens of billions of pieces, technical requirements are not high, prices are very low, and they are generally produced by small butterfly valve factories scattered throughout the country, and their costs are The big butterfly valve factory is difficult to compete with them.
3. Instruments, electronic and electrical butterfly valves, typical products such as brush butterfly valve, on-off butterfly valve, camera butterfly valve, computer keyboard butterfly valve, instrument accessories butterfly valve, there are many leaf springs and special-shaped springs in this type of butterfly valve, and different products have different materials and technical requirements. In the past few years, the domestic instrument, electronics and electrical industry was impacted by imported products, and was generally depressed. The butterfly valve manufacturers supporting it were dragged down. Recently, they have improved and tended to recover.
4. Butterfly valve export market trend. According to customs statistics, in the past two years, China's annual export of butterfly valves is about 22000 tons, most of which are steel plate butterfly valves, and screw butterfly valves account for only a small part of them. The product structure is dominated by daily hardware butterfly valves, and the destination is Hong Kong and Taiwan.
5. The demand of industrial and mineral products for butterfly valves. This market covers other industrial sectors except the transportation industry, from textile machinery cradle butterfly valve to chemical butterfly valve, power station switch, support and hanger butterfly valve, bulldozer butterfly valve, etc. The material, technical requirements and process of products are very different, and the demand for butterfly valve is proportional to the market demand for production materials and the scale of infrastructure projects. Electric butterfly valves are widely used in the self-adjusting air suspension of commercial cars, buses, rail vehicles, machinery and equipment and building bases.
