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