Wenzhou valve enterprises have pioneered the high-end pump market

A huge machine arm, spraying the coating material powder on the substrate that needs to be coated, irradiates a high-energy-density laser beam to irradiate the material, melts it to the surface of the substrate, and rapidly solidifies. When the laser beam ceases to irradiate, the surface of the substrate forms a metallurgically bonded surface coating, which is laser cladding.

In the process of use, the pump valve is in the medium for a long time and is subject to the erosion and corrosion of the medium. High hardness, wear resistance and corrosion resistance are the essential characteristics of the product. After being processed by the laser cladding technology, it can be achieved. The effect is often significantly better than the traditional process. It is with such a new type of cladding technology that Wenzhou pump and valve companies have more technical protection for the development of special wear-resistant ball valves.

It is understood that in the past, high-parametric special wear-resistant series of ball valves were imported, not only high prices, but also wait for a long time, and now the development of high-parameter special ball valves after the market has been recognized by the high-end market, become Imported special ball valve (valve) alternative products, breaking the domestic "special ball valve" import monopoly situation.

Yang Guolai, president of the Wenzhou Pump Valve Engineering Research Institute, said that the valve and valve industry, as one of the five pillar industries in Wenzhou, has occupied more than one-third of the national market share. At present, there are nearly 2,000 enterprises in the city, and the total industrial output value was achieved last year. 31 billion yuan, the sales value of 2016 is expected to exceed 50 billion yuan. However, after decades of development, the Wenzhou valve industry has witnessed severe homogenization of low-level competition, relatively low-end general-purpose products, and the development bottleneck of the high-end pump and valve market, which has prompted more and more of the likes of Chaoda Valves. The same pump valve companies have increased investment in scientific and technological innovation, and marched toward high-end valve products such as ultra-zero-zone, high-low temperature, nuclear power, and coal chemical industry.

In March of this year, Wenzhou City issued guidelines for the implementation of the “Five-one Industry Cultivating and Upgrading Project”. The valve and valve industry focused on the development of high-end pump valves that are resistant to high temperatures, high pressure, and corrosion resistance, and strived to create the nation's largest intelligent system process equipment. Innovative design and manufacturing base, using laser technology to improve and improve the wear resistance, corrosion resistance, high temperature performance and other properties of the pump valve, prolong the service life of the valve is an effective way. Foreign high-end pump and valve manufacturers generally use laser technology. Wenzhou valve and valve leading enterprises are also enjoying the economic and social benefits brought by the use of laser technology.

The Wenzhou valve and valve industry must achieve the goal of upgrading from the traditional block-like economic agglomeration area to the modern industrial cluster. With high-end quality and innovative strength, it won the approval of the high-end pump and valve market, and it is inseparable from the laser technology.
