Drainage valve is an indispensable water industry product. It is mainly used in urban, construction, enterprise water supply and drainage engineering, industrial and domestic sewage treatment and water conservancy projects, among which the main applications are various types of medium and low pressure valves, including Various types of butterfly valves and gate valves, among others, are ball valves, check valves, exhaust valves, plug valves, diaphragm valves, pressure reducing valves, flow regulating valves, and mud discharge valves. Mainly used for liquid discharge or liquid level control.
Water supply field
Industrial and residential water supply is closely related to people's daily life and production work. The water supply network is the bridge between the water supply company and users. The water supply pipe network consists of pipes, valves and other pipe accessories and accessories. In the daily water supply pipe network, water supply, water pressure scheduling and deployment, repair and maintenance of the water stop needs, the connection of old and new pipelines, pipeline flushing, etc., have to open and close the valve, water supply and drainage valve product life and Quality plays a crucial role in the normal operation of the water supply network.
China's water supply industry has passed the construction period and entered a mature stage with the service industry as the main body. As of 2009, there are more than 4,000 urban public water plants in China and the city's water supply capacity is 266 million cubic meters per day. As of the end of 2010, China's water supply pipelines totaled 562,000 kilometers, an increase of 183,000 kilometers from 2005, an average annual increase of 8.2%, and the corresponding water supply valve market demand was approximately 10.55 billion yuan.
Sewage treatment and water recycling are important components of the environmental protection field. With the rapid development of the domestic economy and the improvement of the living standards of residents, the annual discharge of industrial sewage and domestic sewage is also increasing. Since 2004, the capacity of China's sewage treatment market has expanded rapidly, and the daily sewage treatment capacity has been increasing year by year. In 2009, more than 2,000 urban sewage treatment plants have been built in China, and the daily processing capacity has reached 99.58 million cubic meters, a year-on-year increase of 9.8%, more than doubled from 2004.
According to statistics, in 2010, the total discharge of sewage in the country reached 75 billion tons, and the corresponding fixed investment in sewage treatment facilities is also increasing. As of the end of 2010, China's drainage pipelines totaled 391,000 kilometers, an increase of 150,000 kilometers compared to 2005, with an average annual growth of 10.2%, and the corresponding demand for drainage valves reached 6.81 billion yuan.
The construction of flood control, drainage, irrigation, water supply and drainage, hydroelectric power generation, water and soil conservation, water resources protection, and other projects that incorporate water conservancy infrastructure management are also important application areas for water supply and drainage valves.
According to the national statistics, there are currently 37, 000 dangerous reservoirs in the country with a disease risk rate of 43.3%. Among the dangerous reservoirs listed in the special plan for the national dangerous reservoirs reinforcement and reinforcement, 3,642 of them are being reinforced, and there are 7,611 waters. Destructed reservoirs are in urgent need of rehabilitation; in addition, droughts and floods in China are frequent, floods in southern provinces such as Guangxi, Jiangxi, Fujian, and Hunan continue to occur. Meanwhile, western and northern regions such as Gansu, Inner Mongolia, and Shanxi are facing “engineering water shortages”. test.
In order to accelerate the investment in the infrastructure of the water conservancy industry, the state has continuously increased its capital investment. In 2010 alone, the entire society implemented a total of 270.76 billion yuan of investment in water conservancy fixed assets and completed investment of 231.99 billion yuan. A number of major water conservancy projects such as the Huaihe River, Taihu Lake, and Dongting Lake, and the major rivers and lakes in the quake-hit areas in Sichuan were intensified.
