First, the valve market characteristics at home and abroad From the valve market point of view, there are two main: 1, the domestic market, the domestic market is divided into new construction and expansion of the project market, the old equipment maintenance, transformation project market. From these two market point of view, the ordinary valve products seriously oversupplied, and secondly, companies actually phase pressure, disorderly competition, fake and shoddy ... ..., the market is not standardized, leading to some valve manufacturers in the fierce competition In recent years, a substantial loss. From the needs of these two markets, with the development and improvement of the market economy, especially the Progressive World Trade Organization (WTO), its market changes are getting bigger and bigger, and the enterprises are more and more deeply affected by the market. Users' The demand for products is getting higher and higher, and the demand for product development and production cycle is getting shorter and shorter. 2, foreign markets. Foreign markets are very active in recent years, the competition is fierce. The valve import and export in East Asia and Southeast Asia increased rapidly. The market trade between developed countries in North America, such as the European Community, continued to develop. The exports from Germany, Italy, Japan, China and other countries and regions expanded. The import from the United States, Britain, France and other countries increased rapidly. Growth, forming a support valve for the international valve market prosperity, Furthermore, due to the further internationalization of the world economy, multinational companies will continue to promote the development of the international valve market, the regionalization of international trade is to become another major feature. Second, the domestic market China's valve production of about 2,300 more than three, can provide several major categories of valve products, more than 3500 varieties, more than 40,000 specifications. (1) Urban Construction Valves: Urban construction systems generally use low-pressure valves and are currently being developed in an environmentally-friendly and energy-saving manner. Environment-friendly plastic valve, balance valve and the middle of the butterfly valve, metal butterfly valve is gradually replacing the low pressure iron gate. Domestic urban construction valves are mostly balance valve, soft seal gate valve, butterfly valve and so on. (2) urban heating valve: city heat system, the need to use a large number of metal seal butterfly valve, horizontal balance valve and direct buried ball valve, because of such valves to solve the pipeline longitudinal and transverse hydraulic imbalance problem, to achieve energy saving, heat balance the goal of. (3) Environmental protection valve: In the domestic environmental protection system, the water supply system mainly needs the midline butterfly valve, soft seal gate valve, ball valve and exhaust valve (used to eliminate the air in the pipeline). Sewage treatment system is mainly required to use soft seal gate valve, butterfly valve. (4) city gas valve: city gas accounts for 22% of the entire natural market, the valve dosage, its type and more. Mainly need ball valve, plug valve, pressure reducing valve, safety valve. (5) Long-distance pipeline valves: long-distance pipeline mainly for crude oil, finished products and natural pipelines. The amount of such pipelines need to use the valve is forged steel three-way full-diameter ball valve, anti-sulfur plate gate valve, safety valve, check valve.
