The recovery of demand in the machine tool market is expected to be more and more serious in the next year. The rate of decline in order volume was unexpected. Japan’s domestic demand has been reduced. It’s not surprising that the United States has clearly emerged. The reason for accepting Dingdan’s situation is that it’s the first reason in many countries. Last year’s machine tool orders related to information technology were better. This year, the machine tools that are mainly related to the technology industry are mainly used for half-time production enterprises; the expansion of sales channels that Dingdan has drastically reduced and replaced is difficult to appear. Especially the sergeant; the buying situation is very deserted. 4 to mid-August. The order maker next year; has not yet begun. Also. The Japanese companies' large-scale transfer of production bases overseas has also greatly affected the increase in the number of machine tool orders in Japan. The machine is out of the way, and the situation is not pleasing 19 years later. The US equipment search boom seems to have come to an end. Recently, the ten issues have been in the process of taking orders in the same period last year, but it should be pointed out. Not all machine tool sales orders in all industries are in a decreasing trend. For example, in addition to electric aviation, equipment investment in oil-related companies in the United States is also extremely strong. Orders such as large lathes are in good condition, by contrast. The European economy seems to be better than the United States, so Japanese machine tool manufacturers, mainly based on Big Bear, are turning their investments to Europe. Planning to launch production and sales activities in Europe.
In 2000, the total order volume of the Japanese machine tool industry was 975 billion yen, which is expected to drop to 8.5 billion yuan in 2001. The recovery of machine tool demand in the domestic and foreign markets will be the earliest after the summer of next year to reduce costs. Looking for a production and sales market overseas will be an eternal course for Japanese machine tool manufacturers. Beijing Jingcheng North CNC Machine Tool Co., Ltd. was established to develop the CNC machine tool industry according to the Beijing Ten Plan and Beijing Jingcheng Electromechanical Holding Co., Ltd. The spirit of traditional industries.
In order to revitalize Beijing Machine Tool to make it bigger and stronger, the original Beijing Machine Tool Plant was relocated as an opportunity to reorganize the personnel of the Beijing Municipal Government and Beijing Jingcheng Electromechanical Holding Co., Ltd., October 3, 2001, Beijing Jingcheng North CNC Machine Tool The limited liability company was formally announced. The company integrates the excellent assets and human resources of the former Beijing No. 1 Machine Tool Plant and Beijing No. 1 Machine Tool Plant, and absorbs the social assets to achieve the goal of modernizing enterprises, and establishes a corporate governance structure created by modern enterprises with diversified investments; The new company will use advanced foreign technology ideas and equipment as a means. Established a new modern CNC machine tool production base in Shunyi Industrial Development Zone, Beijing; The production operation mode in the middle and the production organization in the production workshop with the new concept of the 21st century network factory realize high quality. The goal of high-efficiency mass production of CNC machine tools; relying on computer network technology, the company is expected to be fully operational in 2005. At that time, sales revenue of 1 billion yuan will be realized. Strive to enter the ranks of the top 20 in the world of machine tool manufacturing in 10 years.

Wafer type check valves have Short face-to-face dimensions and low weight, and provide an economical, space-saving solution when compared to traditional swing check valves.
Dual-plate Wafer Check Valve
Dual-plate check valves are are bonnetless and mounted between pipe flanges (wafer style). In this case, the valve includes two spring loaded half-moon shaped discs that rotate about their shaft. The actual designs of these valves vary between design models and manufacturers. Most have multiple flat seats. The dual-plate Check Valve disc has short rotational disc travel and responds quickly to flow stoppage or reversal, thus the potential for moderate water hammer does exist. It is somewhat better than the Swing Check Valve at minimizing potential water hammer, but with a much higher pressure drop.
Depending on the design, maintenance effort ranges from relatively simple to difficult. All dual-plate check valves must be removed from the line to perform maintenance due to the bonnetless design. The dual-plate check valve also results in a higher pressure drop when compared to a Tilting Disc Check Valve of the same size.
Single-plate wafer check valve
Single-plate wafer check valves(lift type) prevent reverse flow with disc movement that is parallel with the flow. With this design, the disc is always in the flow path. Discs are spring-loaded to assist in seating.
And another thin type single-plate wafer check valves are swing type, that performs the same with swing check valve with much less cost. The disadvantage of this single-plate wafer check valves is, the inside diameters of the valves can only meet 60-80% of Norminal Pipe Size(NPS), which limits the flow coefficient.
