More than half water shortage, more than 100 city serious water shortage, water consumption will incremental 9,000,000 m every year on average3/d.Particularly Environment control
One of key of pollution is sewage disposal, is attached most importance to administering Taihu Lake, Hongchehu Lake, Chaohu and Huaihe River, three rivers, the Liaohe River, Haihe River, and
It is required that the scale sewage treatment plant of more than 2 is at least set up in city above county level.Therefore, valve industry is also presented greatly quite
Machine, the existing thousands of size valve plants in the whole nation, its technical force and production equipment scale are different, and the kind of valve has more than 3,000
Model, more than 30,000 specification.In sealing property, intensity requirement, regulatory function, performance and fluid property, particularly sealing
Can, there is significant progress, but leakage phenomenon still has, and is not consistent with the requirement pole of modern economic construction, still there is larger
Gap.
