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.

The development trend presents new features
26 years from 3 to April, the engineering machinery industry overall showing "unconventional" growth, which accounted for the growth of construction machinery market total sales volume of more than 6% excavators, loaders, bulldozers, cranes four aircraft is so unexpected, some areas began to tight supply situation. This situation first appeared in the East China market and the southwest market. After that, the situation of supply shortage began to spread to most provinces and autonomous regions in china. By April, this trend is increasingly obvious, many models began to appear in short supply phenomenon, some even appeared out of stock". At present, the rapid rise in sales of products once again break the Convention, the two years in the doldrums of the construction machinery industry has pulled to a new height of growth. Domestic construction machinery market only after a year and a half silent, and began to quickly enter the next round of economic growth cycle? From the 8 kinds of product engineering machinery industry association monthly monitoring, as of 26 at the end of June, the main products of the total sales growth of 24.6%, the growth rate is 3.9 times 25 years. The impact of macro-control of small loaders and forklifts are still growing strong trend of development, 25 years of stagnation or decline in sales of the automobile crane, hydraulic excavator, bulldozer showed a strong rebound in the trend of substantial growth, at the same time, grader, roller, paver products have better performance. In addition, part of the commodity concrete machinery enterprises in 5 and June appeared in short supply.
Market demand for enterprises is a good opportunity, enterprises should do everything possible to seize this opportunity to create more sales and profits. But we need to pay attention to the following points:
() maintain the stability of product quality;
(2) we can increase production as much as possible, rather than blindly expand production scale;
(3) do a good job in the market demand forecast, arrange production ahead of schedule, which requires enterprises to achieve sophisticated management in the market management;
(4) to do something to improve the equipment return rate and shorten the recovery period of investment for the user, market growth depends not only on the sales channels, should be a deeper look at this problem, the whole circulation chain of interests is more important, the hands of the user equipment can not play a good benefit, will inevitably affect the two buy. It's time for our business to think about how to really help users improve the efficiency of the equipment. It is more important to pay attention to quality than to pay attention to sales. Enterprises should do well first, not bigger.
So, the current "high growth" situation can continue for a long time will be difficult to judge, but there is a basic judgment is that the domestic construction machinery market will maintain long-term growth. Because China's demand for construction is very large, especially in the near future infrastructure construction, energy construction, mineral resources development, etc., are the main factors driving the construction machinery market continued to grow.
The development of construction machinery is mainly based on the national industrial policy and market environment. Construction machinery industry by the national macro-control policy impact is obvious, but also once again showed that the construction machinery market development trend and the whole society fixed asset investment growth pull has a close linkage. Since the beginning of 26 years, the growth of fixed asset investment has been rising month by month, reaching 3.3% in the first five months, of which the northeast region reaches 39.8%, the central region is 38.33%, and the western region is 32%. The situation with the central government to accelerate the revitalization of northeast old industrial base, the rise of the central region, the western development policy, increase the temperature of the rapid growth of investment, only a quarter of China's lending has reached half of the annual lending target, and the Central Committee put forward the macroeconomic regulation and control goal of fixed asset investment growth control within 2%. The development of ideas instead of extensive development to the development of energy saving and benefit model is not consistent, this problem has already caused the attention of the State Council and the monetary authorities.
In the near future, the central government will increase the investment in fixed assets too fast, the money supply is high, and the credit supply will soon be red light; the next step will be to control the money and credit, and strengthen the investment control of fixed assets. The growth of fixed assets is relatively fast and the growth of credit is relatively fast, so the proper gate of credit is still an important means to prevent the rebound of fixed investment. All these indicate that the problems have aroused the vigilance and concern of the government, and the government is likely to regulate the economic operation again. Therefore, the construction machinery industry closely related to it must pay attention to the changes of macro-control. But overall, from the national "11th Five-Year" plan, the next 5 years, driven by fixed asset investment, the construction machinery industry as a whole will show rapid development, but it will not rise steadily, it is likely to show a ladder upward trend.
The competition pattern is abrupt
It is reported that there will be two major strategic groups in the construction machinery industry in the future: an expert enterprise providing all line products 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.
Industry downturn, foreign investment to accelerate the pace of mergers and acquisitions. With the implementation of national macro-control policies, the national fixed asset investment especially the land resource constraints and the tightening of bank credit policy, the customer's ability to pay, and production enterprises appeared sluggish sales and a backlog of products, coupled with the increase in accounts receivable increased and the proportion of bad debts, so that some enterprises are facing the risk of funding strand breaks. The manufacturers of construction machinery have been expanding their capacity after the blowout of the industry, but at the same time they have suffered a sharp decline in demand, resulting in the plight of most enterprises. This has provided an excellent opportunity for transnational enterprises to covet the construction machinery industry in china. As we all know, when an industry boom cycle is at the bottom, the cost of mergers and acquisitions will be lower, which is more conducive to foreign capital enterprises to acquire and integrate domestic enterprises with their capital advantages. In recent years, we found that the production and export volume of our domestic loaders has been increasing at a relatively rapid pace, but the profitability of the production enterprises is not optimistic. Because of the large number of enterprises and the blind expansion of production capacity, they failed to gain the control position, thus forming a market structure with vicious competition in the low value-added production link. When domestic enterprises are struggling in the quagmire of price wars, there are indications that foreign investment has increased their investment in China. Caterpillar, the world's largest maker of machinery, has announced plans to invest billions of dollars in China's construction machinery market. Faced with such a powerful offensive of foreign investment, domestic enterprises are facing difficulties in mergers and acquisitions.
Policy support is relatively weak. Formulation of the "11th Five-Year" planning for upgrading the content of optimization of industrial structure in the country, stressed the need to improve the level of domestic production of major technical equipment, the state will be mainly in the field of clean and efficient power generation and transmission, large-scale petrochemical, advanced transportation equipment, CNC machine tools, automation control, integrated circuit equipment and advanced power unit to strengthen the policy support. So you can push it
