November 19, 2011, by the China General Machinery Industry Association, the Stove Valve branch organized Tianchen engineering companies, engineering companies race Ding, Hua Lu engineering company, Shenhua Baotou Coal Chemical Branch, National Coal Chemical Co jointly stations and other units of information, Shanghai Group, open the valve hi-dimensional gas of domestic contractors to promote the successful technical seminar held in Shanghai. The success of this seminar was held, not only is the first large-scale professional seminars oxygen shut-off valve feature technical sessions, but also marks the oxygen gas shut-off valve of the localization process has taken an important step.
The seminar also received from received from Shanxi Fengxi, Ningxia Coal, Sinopec Shanghai Engineering Company, Sinopec Nanjing valve center, Jinling Petrochemical, Nanjing Chemical,, Yankuang Guohong, Hubei Dahua, a pioneer in Yunnan and other numerous large-scale enterprise groups hundreds of technical experts to support. The experts of the oxygen gas shut-off valve for the localization of technical topics carried out to promote multi-faceted, in-depth technical exchanges and discussions. From Tianchen, race Ding, Hua Lu, Shenhua Baotou Coal Chemical, Shanxi Fengxi technical experts and a number of units for a keynote speech, while the oxygen shut-off valve for the gas of the import conditions and in the course of conduct problems a lively exchange and discussion. At the meeting, from Shanghai to open technology center hi-dimensional beam with Fund Manager of the company's gas shut-off valve of the oxygen domestic technology research carried out summary report to the company's experts demonstrated the oxygen shut-off valve enterprise standards, process , and other key aspects of quality assurance system log files. After the meeting, all the experts to Shanghai to open the valve group were hi-dimensional tours, and tours of the company's focus on the oxygen production process valves, including: degreasing processes, ultrasonic cleaning process, fat-free assembly plant, foam packaging key processes, has been endorsed unanimously by the participating experts and affirmation.

Oxygen shut-off valve is widely used in various chemical, petrochemical, steel, metallurgy, air grading industry, in which conditions are flammable and explosive dangerous environment, any leakage or leakage can cause intense burning, explosion and other serious consequences, long-term dependence on imports for many years, and the expensive equipment investment and service delivery lag, prompting the immediate localization of the valve. The technical seminar was held successfully, shut-off valves for gas made of oxygen, the process has very important significance, specifically in the following aspects: First: oxygen shut-off valve as a coal gasification plant in the key process equipment, for many years to rely on imports of valves, equipment costs into a larger, service delay, multi-faceted efforts to promote the localization of the valve has become the industry consensus. Secondly, through this technical seminars, exchange of learning related to each unit in the context of all relevant processes use oxygen shut-off valve and problems, and solutions for the problem made a very valuable solution for the production site of application is instructive. Third: D hi to Shanghai to open the Safety Valve Burner Valve of the domestic group, represented by localization of the oxygen shut-off valve of the initial success of technology research, production hardware has taken with the oxygen valve production conditions, the follow-up can be made to carry out related research and development of technical cooperation.

Finally, experts in the field have reached important consensus document minutes of the meeting, read out by the conference's host after all delegates adopted by acclamation, marking the gas shut-off valve of the oxygen to promote the localization of technical seminars to achieve substantive results.
