The valve quality excellent key still improve the management level

    Zhejiang Province this year, a province-wide emergency to carry out special clean-up of the failed relief valve only Pujiang County seized poor quality pressure reducing valve 691. The industry believes that, although the pressure relief valve is a small part, but in the middle but reflect the quality status of the domestic valve is not optimistic Bazhu Valve quality from the source, the key is to raise the level of corporate management.

    It is understood that China has a valve manufacturer about 6000, the annual output value of more than 5 million yuan of 900. "China valve village" --- Zhejiang Yongjia County Valve Industry Association data show that only the county produced valves up to 300 more over 3000 specifications, widely used in large state-owned enterprises and key projects. Some domestic production valve many exist leakage endoleaks appearance quality, short life, the operation is not flexible, and reliable the valve electric and pneumatic devices are not shortcomings, some products are only equivalent to the international level of the early 80s of the last century. Experts predict that, valve market growth, mainly in the power, petrochemical, fertilizer, environmental protection and other areas, for valve business, who has good technology and excellent quality, who can continue to develop new products, who will be able in the fierce competition in the future to seize the initiative.

    Experts suggest that to improve the quality of the valve must be in production management, technical level, new product development efforts. First, to strengthen management. Production and technology management as soon as possible with international standards, and to accelerate the adoption of international standards and foreign advanced standards, increase investment, and the introduction of modern, automated equipment, and innovations to existing products. Meanwhile, the valve business response to the casting and forging raw material selection, casting and forging process, heat treatment, and other effective measures are taken, the rough castings and forgings inherent quality and appearance to meet international standards. Second, we must vigorously develop the high-tech new products, focus on large-scale petrochemical, oil and gas gathering and transportation pipelines, coal liquefaction, and major construction projects, such as supporting the valve new development, such as the 80-ton and above Ethylene Cracking Furnace export pipeline supporting high temperature valves large diameter high pressure ball valve, large diameter pipeline ball valves, LNG cryogenic valves. Thirdly, valve internal and external leakage research should be strengthened, strictly mechanical process, vigorously promoting the development of new sealing material, to improve the machining accuracy of the product key parts to extend the life of the product, a short drain "phenomenon of the valve to be radically improved.
