The future development and application of pneumatic ball valve are mainly reflected in the following aspects: Dongfeng pneumatic ball 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. The pneumatic ball valve is widely used in the self-adjusting air suspension of commercial cars, buses, rail vehicles, machinery equipment and building bases.
Here, based on my own work experience, I summarized and compiled the following installation precautions for pneumatic ball valves that we often see in our lives for you to share:
Do not use pneumatic ball valve beyond the recommended safe extension height
In order to extend the service life of the pneumatic ball valve, do not use the pneumatic ball valve below. low compression height

Do not use the pneumatic ball valve when the pressure exceeds 0.7Mpa. Do not use the pneumatic ball valve in a twisted state
Attention: ★ Instructions for storage, transportation and use of pneumatic ball valve
1. Transportation, loading and unloading shall be done without rough work
2. It should be stored in a dry and ventilated warehouse to avoid direct sunlight.
3. The installation position shall have enough installation space to avoid contact with oil, acid-base substances and sharp substances.
4. Avoid touching the pneumatic ball valve with sharp tools: the matching parts shall be smooth without edges and corners.
Note: Please do not inflate the components without any restrictions. Components must be limited by suspension or other suitable structures. Do not exceed the pressure recommended in the design manual. Improper use or excessive inflation will cause component damage, function damage or severe personal injury.
Dongfeng pneumatic ball valve can realize the functions of support, buffering, braking, height adjustment and angle adjustment by using the air elasticity. The product works without external power, and is stable in lifting force. It can stretch freely (the lockable balloon valve can be positioned at will). It is used more and more widely, and there are more and more industries that need it.
