The straightening frame adopts hot rolling process, which has beautiful appearance, stronger rigidity and good straightening effect.
Adjustable speed traction ensures reliable feeding and avoids scratches or damage to the steel bar. The programmer used to control the straightening and cutting process can remember 20 settings of different length and different number of steel bars at one time. , All batch settings can be completed on the digital display. The operation is simple and fast. The straightening wheels, square blades and round blades are heat-treated (quenched) high-quality alloy steel support, which can work under heavy load and use long life

Recently, CNS Su Valve received an order from PetroChina Liaoyang Petrochemical Co., Ltd. for ordering DN56? (DN1400mm) ultra-large-diameter bevel gear special valve for low-temperature gate valve, mainly used in 200,000 tons/year of ethylene and its supporting renovation project (ethylene part ) The localization of the device is also the first device to use domestically produced low-temperature valves. After this assembly, the total height of the entire machine is more than 5 meters. The valve of the large-diameter valve with a weight of more than 16 tons is also the first designed and processed. , Manufacturing, the original large diameter cryogenic gate valve mainly rely on imports, but also foreign monopoly products.
In the face of this extremely high-level special valve that has a high height and fills the large-diameter cryogenic ball valve in China's valve industry, after the company received the order, the engineering and technical personnel of the R&D center and related departments have invested intense research and development. Manufacturing, because this valve is large caliber, suitable medium temperature -40 degrees to +100 degrees, the technical difficulty is great, the material used for the valve seat is made of extraordinary carbide. The pressure is 150LB/2. 5MPa, wedge-type flexible single gate structure, delivery time is tight.
In order to ensure the success of this high-pump, large-format flat gate valve, throughout the entire manufacturing process, the company's various departments worked together, the R&D center designed a group of thoughtful designs, the quality department strictly controlled the quality of the parts, and planned the production department’s External resources support, careful preparation of the special valve factory before assembly and cooperation of the tooling, they in order to complete the final assembly? The engineers and technicians of the company have carefully analyzed and reduced the operating height, thus completing the assembly of the complete machine on the basis of high efficiency and safety. After the company's efforts, the expansive object finally succeeded in trial production, and passed strict inspections after passing the test. The price of the whole machine was only one third of that of foreign countries and was highly appreciated by users.
Another report: The nuclear grade all-welded jacketed vacuum gate valve independently researched and developed by China Nuclear Sohu Technology Industrial Co., Ltd. has been successfully developed. Recently, it has passed the inspection and appraisal of the prototype of the new-level experts organized by China National Nuclear Corporation. The new technical performance has reached the international advanced level and has filled the domestic gap.
The original vacuum valve used in the domestic nuclear fuel system industry was imported from abroad and was expensive, and became one of the monopoly nuclear products of foreign technology. However, many quality problems were found during use, resulting in leakage of valve pipes and high maintenance costs. Users have asked for independent research and development of the Soviet valve to replace imports. To this end, the company will work with the national nuclear power design institutes to undertake this localization research project. The difference between the vacuum valve body and the valve body is extraordinary. Its technical performance must meet the extraordinary requirements of 1.33×10-5 Pam3/S and a pressure of 25 kg. That is, when vacuum welding is performed, no air can enter and There are leaks, the degree of sealing is quite high, and vacuum requirements are even higher. So far domestic manufacturers have been unable to overcome their key technologies. After the company's research and development center's arduous efforts, the concerted efforts of the manufacturing department finally succeeded in trial production. Its various technologies reached the design requirements, and recently passed the ministerial-level new technical appraisal. The appraisal conclusions have improved the original imported valve for its new product. Many defects, using a new design concept, using the world's most advanced technology, the valve has made a comprehensive improvement, and the technical performance is better than foreign products, the valve body also uses the full welding technology, the product price is only foreign three One in a minute. Based on the prototype of the successful trial production, the company also carried out mass production. At present, they have provided special batch of special vacuum gate valves for Qinshan Nuclear Power Station Phase II and China’s nuclear power projects for foreign aid.
Recently, CNNC Su Valve Technology Industrial Co., Ltd. was the domestically-developed project of ethylene and ancillary engineering equipment of PetroChina Liaoyang Petrochemical Co., Ltd. The independently developed DN56 "(DN1400mm) large-diameter bevel gear low temperature gate valve has been successfully trial-produced. According to the design requirements, the gate valve has recently been delivered on schedule and the project has been installed and used recently. The success of this new product not only rewrites the record of the valve industry's large-diameter cryogenic gate valve, but also marks China National Nuclear Technology’s valve for China. Manufacturing industry has made new contributions, so they are at the forefront of the industry in the development of special valves, have developed a large number of special valves in the petrochemical, nuclear power and other fields, a lot of special valves to achieve localization, replace the import, also Singing the main theme of independent innovation, it is worthy of being the vanguard of the special valve of the valve industry in China. Recently, the company was also awarded the Jiangsu Provincial Special Valve Engineering Technology Research Center by the Science and Technology Department of Jiangsu Province.
