Valve sealing is an important guarantee for the quality of the valve Now the machinery industry is developing more rapidly, as the valve in the industry is no exception, we all know that the valve industry is an important branch of our general machinery. Its products as a key fluid control device is widely used in petroleum, chemical, metallurgical, power, urban construction, environmental protection and other industries. At present, the valve manufacturing industry is in a very favorable opportunity for development. The reason why, following with the hydraulic control valve center on the reasons for the development of valves and future development prospects: the sustained and steady development of state-owned economy. Investment in fixed assets is gradually expanding. In particular, several centuries of project "West-East Gas Pipeline," "West to East," "South-North Water Diversion" and other projects require a lot of valve product support. With the accession to the WTO, the lowering of the threshold of international trade and the adjustment of product structure in developed countries, China is gradually becoming the world's largest processing factory. The processing of valve products is facing more room for development. So how to seize this strategic opportunity to speed up the valve industry. The author believes that we should do a good job from the following aspects: First, actively promote the joint reorganization among enterprises, as soon as possible to create a number of large-scale enterprise groups. Valve manufacturing industry currently has about more than 5,000, with annual sales income of more than 50 million only seven, more than one billion five, more than 200 million yuan a business did not. Domestic market share is only one nuclear nuclear Su valve more than 2% of the remaining were below 1%. This scale of business is difficult to produce shock in the market, competition with internationally renowned companies in the industry even more difficult. As soon as possible to change this situation, in addition to their own growth factors, the most effective way is through joint ventures, mergers and reorganization of enterprises to achieve the expansion of capital in order to further expand market share in the competition unbeaten. This is a more popular practice in today's international economy and is also a direction issue for the development of the valve industry in the coming period. In this issue, we should emancipate our minds, break the boundaries of the region, break the boundaries of ownership and break the traditional line of professional division of labor in accordance with the requirements of the 16th CPC National Congress that "there should be a new breakthrough in reform and new ideas for development." As long as there is a joint alliance between enterprises can be bold to do to try to use 3.5 years and strive to create a number of output value of 500 million or even 1 billion yuan of enterprise groups. The second should pay attention to the adjustment of product structure, the courage in technological innovation, research and development of high value-added and international advanced level products. China's valve industry has been able to produce more than 10 major categories of products. Such as globe valve, butterfly valve, ball valve, gate valve, safety valve, check valve, throttle valve, stopcock, pressure reducing valve, diaphragm valve, trap, emergency shut-off valve, the maximum operating temperature of 570 ℃, The maximum pressure 600MPa, the largest diameter 5350MM. Although these products have strongly supported the domestic economic construction, we should be soberly aware that most of our products belong to the general technical content or labor-intensive products, and seldom have the international advanced level. The recent bidding for the main pipeline of the West-East Gas Pipeline, the failure of all our valve enterprises is a regrettable fact. Bitter experience. To promote the revitalization of the valve industry to national industry must implement technological innovation, adjust the product mix, to brave in the research and development of high technology content, high labor-added value of the world's leading valve products such as control valves and automatic valve control valve, three Tongli flow wide, three-way diverter valve, safety valve; ball valve type of metal seal all-welded, high-parameter large-diameter valve; and power plant supercritical C12A alloy valve.
The elevator shaft is the space for elevator operation, which is composed of shaft wall, bottom plate and top plate. The size of the elevator shaft is determined according to the elevator model selection. The shaft wall is installed with elevator rails and counterweight rails, and the reserved door opening is installed with elevator doors. There is an elevator machine room at the top of the hoistway.
