Water supply and drainage valve industry in China Analysis ---2009-10-22
Infrastructure construction is the focus of China's economic construction, water supply and drainage works, especially the sewage treatment works in size, including pipes, valves, including water treatment equipment industry, and has formed a strong water industry, are for the valve industry development, and provides a good opportunity. China has entered WTO, the global annual demand for the valve about 300 million tons, it is necessary to fully utilize and seize this opportunity.
Current situation
Now there are about 3,000 of the size of the valve factory, of which 600 Wenzhou, Zhengzhou, more than 200, Shanghai, more than 150, 250, Liaoning, Jiangsu and Fujian to more than 200, though mixed, but the product has reached more than 3000 varieties of model, nearly 30000 specifications. In a multi-species, sealing performance, strength requirements, regulatory function, action, performance, and circulation performance, especially sealing performance, have made considerable progress. Back a decade ago, urban water supply authorities saying the industry association famously said that "10 valve 9 and missed", although some exaggeration, but it is a fact.
Caused many problems exist in the valve industry, the major reform and opening up, the market has rapidly expanded, while the old state-owned enterprises have Guantingbingzhuan valve Originally, the level of machine-building industry is not high, so township and village enterprises (private enterprises), these rapidly developed, so the starting point is low, technical force is very weak, poorly equipped, the products mostly to imitate the production, coupled with market confusion, especially in low-pressure valves used in water supply and drainage, the problem is serious. The past decade, in a few valves, driven by business, there are indeed significant progress, and some species even reached the international advanced level, there are many enterprises in the second venture. But on the whole, still a big gap, there are a lot of work to do. To this end, were made in 2010, 2020, advances in technology, development planning.
Common valve
In the water supply and drainage project, in the low-pressure valves are widely applied, in particular, large-diameter low-pressure valves (low pressure valve is the valve nominal pressure PN ¡Ü 1.6MPa), while the medium-pressure valves (PN2.5-6.4MPa) than the less. gate valve, butterfly valve leading the most basic and widely used product. Gate valve the use of the oldest countries in the world still in use, especially DN300mm the following, in various types of valves in the still dominant. Characterized before and after the pressure valve plate valve plate so that pressure in the export to the right of compulsory seat, the seal is better, and full-time, due to valve plate does not stay in the flow of the road, the pressure loss. Used to cut off the pipeline media.
