Domestic valve to be upgraded to improve the quality of technical management is the key
Zhejiang Pujiang County, a worker engaged in the processing of crystal parts recently at work, due to the rupture of the valve interface, was severely burned gas. It is understood that the county has recently occurred in succession two due to the use of substandard valves caused serious injuries. In response, Zhejiang Province recently carried out in the province's emergency relief valve failed to carry out special clean-up operations, only Pujiang County seized 691 low-quality valve. Industry insiders believe that although the valve is a small component, but it reflects the quality of domestically made valves is not optimistic. At present, China has a total of about 6,000 valve manufacturers, of which 900 have an annual output value of more than 5 million yuan. According to "China's hometown of valve" - ​​Zhejiang Yongjia Valve Industry Association provides data shows that only the county produced more than 300 kinds of valves over 3,000 specifications, widely used in state-owned large enterprises and key engineering and technical equipment. At the same time, the valve on the high technical requirements, and domestic enterprises currently produced valves generally leakage leakage, the appearance of low quality, short life, inflexible operation and valve electric and pneumatic devices unreliable shortcomings, some products are only equivalent to The international standards in the early 1980s. Experts predict the future growth of the valve market mainly in the fields of electricity, petrochemicals, fertilizers, environmental protection, for the valve business, who have good technology and excellent quality, who can continue to develop new products, who will be in fierce competition Grab the first chance. Experts suggest that to improve the valve quality, must be in production management, technical level, new product development efforts. First, we must strengthen management. Production and technology management should be in line with international standards as soon as possible, speed up the pace of adopting international standards and advanced foreign standards, increase investment, introduce modernized and automated equipment and make innovations in existing products. At the same time, valve companies should deal with the selection of raw materials for casting and forging, casting and forging process, heat treatment and other links to take effective measures to make castings and forgings rough in the internal quality and appearance to the international level. Second, we must vigorously develop high-tech content of new products. Experts predict that during the "Eleventh Five-year" period, the development of petrochemical valves will focus on the development of new valves for major projects such as large-scale petrochemicals, oil and gas pipelines and coal liquefaction, such as cracking of 800,000-ton ethylene plant or above Large-diameter high-pressure ball valve, large-diameter high-pressure ball valve, LNG low-temperature valve and other needs will have a greater growth, the valve industry is expected "Eleventh Five-Year" total demand will reach 34.5 billion yuan. Third, we should strengthen the valve leaks, strict mechanical processing technology, and vigorously develop and promote new sealing materials, improve the precision of key parts of the product, extend the service life of products, so that the valve "a short two leaks" phenomenon has been fundamentally improved.
