Industrial Valves are Gradually Moving Forward
Infrastructure construction is the focus of my country’s economic construction. Water supply and drainage projects, especially sewage treatment projects, have a large scale of water treatment equipment manufacturing, including pipelines and valves, which has formed a powerful water industry. It provides a good opportunity for the development of the valve industry. my country has entered the WTO, and the global demand for valves is about 3 million tons per year. It is necessary to make full use of the valve industry’s labor-intensive, poor labor conditions, low per capita wages in my country, and the transfer of production from developed countries to developing countries, and actively move toward the platform of the world economy. Briefly describe the current situation and development of water supply and drainage valves in several topics.
The current situation
Now there are about 3,000 large and small valve factories, including 600 in Wenzhou, more than 200 in Zhengzhou, more than 150 in Shanghai, 250 in Liaoning, and more than 200 in Jiangsu and Fujian. Although good and bad, the product variety has reached more than 3,000 models. , Nearly 30,000 specifications. In terms of variety, sealing performance, strength requirements, adjustment function, action performance and circulation performance, especially the sealing performance, there have been considerable improvements. Ten years ago, the authority of the Urban Water Supply Association had a famous industry saying that “ten valve “Nine Leaks”, although a bit exaggerated, it is a fact.
The many problems that have caused the vacuum valve industry are mainly due to the rapid expansion of the market after the reform and opening up. The original state-owned valve companies have shut down and transferred. The level of the machinery industry was not high, so township enterprises (private enterprises) have sprung up and developed rapidly. , The starting point is low, the technical force is very weak, the equipment is simple, most of the products are imitated, and the market is chaotic, especially the low-pressure valve for water supply and drainage, the problem is serious. In the past ten years, driven by a small number of valve companies, there has indeed been significant progress. Some varieties have even reached the international advanced level, and many companies have started their second ventures. But on the whole, the gap is still large and there is a lot of work to be done. For this reason, it is of great significance to make technical progress and development plans for 2010 and 2020 respectively.
