Valve industry in China has been developed for several decades, during this period, the valve standard has also made considerable development. However, the technical content and appearance design of the valve industry are still the focus and difficulty of development. At present, the domestic valve products have been able to meet their own needs. Therefore, it is even more necessary to expand exports and expand the market. After decades of development, China's valve manufacturing industry has made great strides. At present, the number of valve enterprises in China ranks first in the world, the valve production level has also been greatly improved, and the valve output has been greatly increased. At present, there are many valve enterprises in China and the development of the valve industry is relatively mature. In particular, the product categories have been greatly improved, including gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves and plug valves , Pressure reducing valves, diaphragm valves, steam traps, emergency shut-off valves, etc. have been developed. At present, China's valve market, the total annual demand of less than 10 billion yuan. According to the scientific concept of development, in order to ensure the coordinated economic development in the future and the improvement of people's livelihood, our country will inevitably put emphasis on infrastructure construction such as water, electricity, gas and heat. This is exactly where the valve comes into play. In other words, as a new type rather than replacement of the Chinese valve market, the potential and explosive demand will be staggering. Although the overall level of the valve industry has been greatly improved, but the quality is not stable enough, such as running, running, dripping, leakage phenomenon often appear in domestic valves. In addition, China's valve supporting capacity compared with the developed countries there are still some gaps. In addition, the valve industry in China is still dominated by small and medium-sized enterprises. At present, the competition in the industry is mainly the competition of low-end products. Informal competitive measures are disrupting the development of the market and causing great damage to the valve manufacturing industry. As the rapid expansion of the market, the original state-owned valve enterprises have shut down and turn "during the 12th Five-Year Plan" China's high-end equipment localization of parts and components will be further strengthened. In China's current valve market, in addition to low-pressure valve has reached the international market can accept the level of high-pressure valve still have to rely on imports. Therefore, to improve China's domestic product level and grade valve, the valve industry is the development of the first major breakthrough. In 2012, China's valve industry import and export volume reached 24.1 billion U.S. dollars, an increase of 28.2%. Among them, the total export volume was 22.4 billion U.S. dollars, up by 29.3% over the same period of previous year. The total amount of imports was 20,134 million U.S. dollars, up 27% over the same period of previous year. As the world economy picks up, the import and export of valve products in our country have also increased. By 2015, China's valve market will be 10% larger than the U.S. market and four times as large as the Japanese market. Buyers will buy 2.4 billion U.S. dollars worth of valves. By 2015, three of the Top 10 buyers will be in Asia, as well as six of the top 20. At present, there are about more than 3,000 valve manufacturers in China, ranking the first in the world in number. However, most of them are low-level, small-scale and family-run enterprises, with an annual sales income of 500 million yuan less than 500, with annual sales income of 100 million yuan only a dozen companies, the market share of the top 10 companies Of the total market share of enterprises only 8% to 9%. Due to industrial concentration is too low, resulting in technical backwardness, low price competition, the lack of influential brands and many other negative factors, making such a huge Chinese valve market up to now there is no real sense of the brand name. With the acceleration of the reorganization of the valve industry, the future industry will be the competition between valve product quality and safety and product brand, and the product will develop towards high technology, high parameter, high corrosion resistance and high life expectancy. China's valve manufacturing industry in the huge demand environment, will show a better development prospects. And we should continue to make full use of existing standards at the same time, look to the future, to develop new standards and new systems that can be applied to the future development, so as to promote the valve technology to a higher level of development and continuously improve the level of valve products and grades . I believe China's valve industry in the huge demand environment, will show a better development prospects.
Perilla seeds (Fructus Perillae) are the seeds of perilla, a plant of the Lamiaceae family. It can be used as seasoning to remove fishy smell, increase freshness and enhance flavor. At the same time, it has certain medicinal value, and has the effects of lowering Qi, clearing phlegm, moistening the lungs, and widening the intestines.
Efficacy and role:
1. Lower qi and resolve phlegm, relieve cough and relieve asthma: Perilla seeds can relieve qi stagnation, relieve asthma and eliminate phlegm, treat cough with excessive phlegm, and chest and diaphragm fullness and tightness. They are often used with tangerine peel, pinellia, magnolia bark, etc. to lower qi and resolve phlegm. . For those who suffer from food stagnation and fullness, it can be used together with white mustard seeds and radish seeds to digest food and resolve phlegm.
2. Loose intestines and relieve constipation: Perilla seeds contain a large amount of natural oils, which can lubricate the intestines and have a good therapeutic effect on intestinal dryness and constipation. They are often used with hemp seeds, almonds, and trichosanthes seeds.
