GDC-J series electromagnetic high vacuum flapper valve is a valve which is opened or closed by electromagnetic force and spring reset force. It is suitable for opening or separating airflow in vacuum system. When the valve is closed, the upper side of the sealing surface of the valve plate is allowed to bear atmospheric pressure, and the lower side is vacuum. Under this condition, the valve plate can be opened normally after the power box is connected to the power supply.
The suitable working medium is air, non corrosive and dust free gas.

Relevant information
Welcome consultation
The policy support for the localization of construction machinery in the future will be relatively weak, and domestic enterprises need to rely more on their own strength and transnational confrontation. Transnational industry has certain advantages in product innovation, quality, reliability and after-sale, and the gradual deployment of its industrial layout will lead to further competition in the industry, and market sales will be further concentrated to large enterprises, the industry will show the stronger the stronger, the weaker the weaker trend. According to industry experts predict, considering our country's water conservancy, railway, highway, power plant, coal, real estate and the Beijing Olympic Games, Shanghai World Expo construction, China's "11th Five-Year" period the average annual construction machinery purchases in 900 million yuan, mainly concentrated in the mining machine, concrete machinery, loaders, forklift etc. product areas. From the current situation of the industry, most of the excavator market has been controlled by foreign enterprises, while the loader market is currently home made in the world, but with the continuous entry of foreign capital is also facing a severe test.
In contrast, concrete machinery is the market demand growth faster, and the degree of foreign investment is relatively low sub industry. The early introduction of the Forbidden City to use spot mixed concrete policy makes the market for concrete pump, pump truck, concrete trucks and concrete mixing stations and other products of the growing demand, favorable external conditions to provide a larger space for development of domestic production enterprises. Expert firms may survive. From the perspective of enterprise competitive strategy, there will be two major strategic groups in the future construction machinery industry: expert enterprises providing products across the whole line and generalist enterprises and subdivision products or markets. At present, the domestic leading enterprises are still relatively weak compared with the multinational strength, while those focused on some products and the market to form the core competitiveness, and the gross profit oriented expert enterprises are more likely to survive in the fierce competition. In the new competitive situation of construction machinery industry, a considerable number of domestic enterprises will become a link in the multinational production and market system, while a few enterprises in the product and core competitiveness will be likely to become the leader of cross-border competition.

Analysis of China's nonferrous metal trade in the first half of 27 years
A large class of non-ferrous metals, import and export trade in the first half of the 27 years of China's total exports of non-ferrous metals categories (including minerals, metals, metal products and scrap etc.) the cumulative number of 768 thousand and 500 tons, an increase of 3.36%, the cumulative amount of 400 million, an increase of 23.25% of the amount, affected by the national macro-control policy, export scale a little, but by the positive impact of international non-ferrous metal prices, the export amount of the continuation of 26 years of gains. Among them, the number of general trade exports accounted for 88.7%, an increase of 65.7%, feed processing trade accounted for only 4.23%, down 76.46%. From the point of view of export commodities, exports are the top five Unforged silver, ferrosilicon, aluminum, iron, manganese, Aluminum Alloy refined lead, mainly raw materials and simple processing products; judging from the export country, mostly exported to Hongkong, Korea, Japan, Thailand, the United States, the United Arab Emirates, India and other countries; from the growth point of view, nickel, cobalt, unwrought zinc export growth rate in all times, the growth rate of nickel was up to 7583 times, the recent LME nickel price highs, a large extent from the Chinese yield increase in nickel pig iron produced by impact. In addition, China has accelerated the pace of eliminating the backward production capacity of iron and steel industry, 3 cubic meters below the blast furnace is located in the list, these blast furnace can be a little modification of the production of nickel iron, which also contributed to the supply of nickel iron. In the first half of 27 years, China imported 320 thousand tons of non-ferrous metals category, the number increased by 5.5%, the cumulative amount of 3 billion 420 million US dollars, an increase of 77.42%. From the point of view of imported goods, mostly in metal minerals, the top 10 were aluminum ores and concentrates, nickel ores and concentrates, copper scrap, copper ores and concentrates, lead ores and concentrates, zinc ores and concentrates, the other half is made of silver, aluminum scrap, unwrought copper refining the cathode and the cathode material, the top 10 imports accounted for 89.7%. From the first half of non-ferrous metals import and export data, the cumulative export of 400 million, the cumulative import of 3 billion 420 million, the trade deficit reached 6 billion 400 million U.S. dollars, an increase of 84%. Two, rare metals import and export trade situation in the first half of 27 years, China's rare metal exports 587 thousand tons, an increase of 58%, the export value of 5 billion 250 million U.S. dollars, an increase of 5%, of which the general trade volume accounted for 95%. The main export commodities in iron alloy, simple forming metal processing products, such as unwrought silver, ferrosilicon and silicon manganese iron, half made of silver. Among them, the total amount of silver exports accounted for 37.47%, an increase of 5%, accounting for 5.6% of the total export amount. Slag sand exports accounted for more than 7%, ferrosilicomanganese accounted for 6.9%. Rare metals exports mainly concentrated in Hongkong, Japan, the United Arab Emirates, South Korea, India and other Asian countries, of which exports to Hongkong accounted for 5%, exports to Japan accounted for 9.6%, exports to the United Arab Emirates increased by 454%. Imports of 96 thousand tons, an increase of 227%, the import amount of 860 million, an increase of%, of which general trade accounted for 78.2%. Among them, nickel, manganese ore and its concentrate accounted for 62.7% of the total imports, an increase of 842%. The other half made silver imports accounted for 5.86%, an increase of 2%, the main import commodities are precious metal minerals and products. From the import and export data of rare metals in the first half of this year, the cumulative export of 5 billion 250 million, the cumulative import of 860 million, the trade deficit reached 2 billion 800 million, the deficit increased by 8 times. Three, 27 years of licensing management of rare metal trade situation, the first half of 27 years, China's license management of rare metal exports 72 thousand tons, an increase of 52.53%, the export value of 300 million U.S. dollars, an increase of 39.7%, of which the general trade volume accounted for 8.54%.
