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
But the high growth industry should not be simply measured by the traditional P / E ratio. In the next -2 years, the wind power industry is expected to usher in its own golden development period, and we still believe that the wind power industry is a bright landscape in the future.

Electrical equipment industry: growing up in policy support
Energy saving and emission reduction has been put to unprecedented strategic height by China. Recently, the central government has added another hundred million yuan of funds to promote energy conservation and emission reduction. We believe that Rongxin shares believe that electricity will benefit from it. The regulation on the purchase of renewable energy by electric enterprises will be implemented on September, and pay close attention to the listing of related wind power equipment.
Industry growth rate of 3% this year
Since the beginning of this year, the electrical industry has maintained a steady growth, high operating situation, 27 months -5 months profit growth of more than 3%, higher than our previous expectations about 25%.
Obvious increase in production and marketing
-5 months, the electrical industry to achieve industrial output value of 68 billion 800 million yuan, an increase of 34.9%. This data is higher than the same period last year (3.32%) higher than 3.87%; -5 months to achieve industrial sales value of 657 billion 300 million yuan, an increase of 33.73%, basically maintained the same period last year (33.9%) similar increase. The main business income of 639 billion 800 million yuan, an increase of 33.55%, slightly lower than last year's 34.7% increase.
Synchronous growth of profits
-5 months, the electrical industry realized a total profit of 34 billion 570 million yuan, an increase of 34.33%, compared with the growth rate of gross industrial output, sales value and main business income increase is consistent, achieved simultaneous growth; from the main business income margin and cost profit rate, -5 months, the main business income margin 5.39%, cost margin was 5.75%, respectively, compared with the same period last year increased by.4% and.6%.
Surplus continues to expand
This year, the import and export trade of electrical industry is still active. In addition, the gap between import growth and export growth is narrowing, but the surplus continues to expand. -5 months, the import and export trade of electrical products continued to grow rapidly, the total import and export amounted to 32 billion 635 million US dollars, an increase of 25.9%. Among them, imports of 4 billion 600 million U.S. dollars, an increase of 8.34%; exports of 800 million U.S. dollars, an increase of 3.4%. The growth rate of 25.9% of the total import and export growth is still rapid growth, but compared with the same period last year and 29.53% last year's 29.6% growth rate, have been reduced by about 4.5%, the growth rate has slowed down. -5 month, import growth of 8.34%, export growth of 3.4%, the difference between 3.7 percentage points, but compared with the same period last year imports growth is lower than the export growth of 4.82% compared to the situation, the gap has narrowed. From the growth range, the gap between the two is quite obvious, the growth rate of imports is still lower than the export growth rate over the same period more than%, and the resulting trade surplus continues to expand.
Speed up development of power transmission and transformation equipment industry
With the transfer of power construction to power construction, the power transmission and transformation equipment industry has entered a fast rising channel. -5 months, transformer output has reached 33993 KVA, and the growth rate is accelerating month by month. From 8.5% in -2 month and 2.4% in -3 month, it reached 2.93% of -5 month. The growth rate has increased by 26 compared with the same period of last year (2.23%), which is 4.4% higher than that of the whole year in.7%. As another big branch of the power transmission and transformation industry, the power cable has continued to grow rapidly this year. -5 months, completed 4 million 793 thousand and 500 kilometers, an increase of 7.85%; the development rate than the same period in 26 increased by 4.45%. We believe that in the background of the power transmission industry speed, leading the growth rate will increase, because we are optimistic about the leading power transmission such as TBEA (quotes, information), high level of electrical (quotes, information), twbb (quotes, information), Sheng shares (market information).
Power generation equipment industry growth exceeded expectations
China's power generation equipment production in the world in the first half of this year still maintained rapid growth, -6 months, the country's 6 kilowatts and above power generation equipment capacity totaled 62 million 350 thousand kilowatts, an increase of 2.8%.
-6 month power generation equipment production increased by 5.6%. According to China national power "11th Five-Year" plan, in the future, the theme of power industry reform will be from capacity expansion, supply and demand improvement to structural adjustment, industrial upgrading stage. 27 years, China plans to put into operation 950 thousand kilowatts installed capacity, at the same time shut down 20 thousand kilowatts of backward installed capacity. At present, more than 6% of new orders for 6MW or higher products, supercritical or ultra supercritical generator share rise, a few years ago the mainstream product 3MW sub critical generator will be eliminated from the domestic market. The market share of the three power generation groups has risen to about 8% in recent years. The market share of the three power generation groups may rise further due to the upgrading of the market demand due to the lack of technology and equipment for the production of high standard products. From the new orders of the three major suppliers, the new orders in the first half of 7 are more than the same period last year. Shanghai Electric Group five years ago 7 month new power equipment orders more than million kilowatts, over the same period last year, Dongfang Electric Group 27 years -5 months new orders amounted to 27 billion 800 million yuan, an increase of%, therefore, we believe that from the current three big power group in the hands of a large number of orders and new orders growth, its performance to maintain a steady growth in 2 years is guaranteed, the current power generation equipment market valuation is relatively undervalued. Renewable energy in full
After the promulgation and implementation of the renewable energy law, another measure to encourage and protect renewable energy power generation - "electric power enterprises' full acquisition of renewable energy power regulation" was officially promulgated in July 25th, and will be implemented on September, 27.
According to this method, renewable energy, including hydropower, wind power, biomass power generation, solar power generation, marine power generation and geothermal power generation, will be fully acquired by electric power enterprises. In addition to large and medium-sized hydropower generation, renewable energy generating units do not participate in bidding, the implementation of high tariff and differential subsidy tariff policy.
The full acquisition of renewable energy in electric power enterprises is clearly required in the renewable energy law. This approach is only to clarify regulatory details and responsibilities. This method stipulates that one of the following acts will cause economic losses to the renewable energy power generation enterprise, and the electric power enterprise shall bear the liability for compensation. These include: no construction or renewable energy project access project construction timely in violation of the provisions; refuse or impede the generation and renewable energy companies signed a power purchase contract, and scheduling agreement; not provided or not timely provision of renewable energy power generation; renewable energy power generation without priority scheduling.
We are now optimistic about renewable energy power generation, because its scale development and cost advantages are higher than other forms of renewable energy except hydropower. We pay close attention to the development of wind power equipment listed Oriental motor (quotes, information), Huayi Electric (quotes, information), Hunan Electric shares (market, information), Changzheng electric (quotes, information) and the Silver Star energy (quotes, information).
The state continued to increase investment in energy conservation and emission reduction
Energy saving and emission reduction has been placed in front of China
