3 Introduction to R&D management process
3.1 The preliminary preparation for R&D is to tackle this project. At the beginning of 2005, we invested manpower and funds to carry out research, focusing on the research and test of core processes. Up to now, we have mastered technologies such as selection of domestic alloy materials, formulation of hot working process, grinding and grinding methods for this project. During the overall development of the project, we focused on the procurement, assembly and commissioning of precision processing equipment (including hot processing equipment), inspection equipment, etc. through bidding, so as to ensure that test data can be effectively obtained in research and development, comparative tests can be conducted, and equipment quality level can be evaluated. We are also going to start small batch production first, and then carry out on-site practical application. By comparing the data of on-site application with the test data, we propose the control points of core technology, gradually form our own product core technology, and form the competitiveness of products, so as to ensure product quality and provide guarantee for mass product manufacturing.
3.2 Key point of research and development project technology High temperature and high pressure metal seat pneumatic ball valve research and development project is mainly applied to ultra supercritical thermal power generation unit (working medium 30MPa, 600 ℃) boiler, steam turbine body and pipeline drainage system to solve the internal leakage problem of drainage valve under high parameter conditions, achieve energy conservation, reduce costs and promote application in domestic power industry The purpose of creating economic and social benefits. In the process of research and development, through design calculation and test data analysis, we believe that this project belongs to the small precision machinery manufacturing industry project. The key points of the project technology are the selection and inspection of metal materials, hot processing technology, thermal spraying and post processing technology of thermal spraying, surface sealing grinding, etc. These technical key points should be grasped to ensure the success of the project.
3.3 The assessment management objective of the R&D project is to connect the throttle hole in series behind the valve and connect the thermal system by bypass. Under the condition of normal operation of the unit, the valve is opened and closed once a day for 20 consecutive days. If there is no internal leakage, it indicates that the requirements are met. This condition is equivalent to the normal service of the valve on the unit for 4 years.
3.4 Process design and implementation mode of the project scheme: establish a research group and a special organization to take charge of the project; Technical route. The parallel technology route is as follows: material selection and hot working process; Machining and process equipment; Thermal spraying and subsequent processing technology and equipment of thermal spraying; Grinding and equipment of annular spherical seal; Inspection technology; Overall coordination, etc. The parallel technology can speed up the development, improve the technical level of each branch, and ultimately ensure the technical level of the terminal products.
3.5 Control and management of project progress The initial research and development work of the project has been carried out since the beginning of 2005, and 300000 yuan has been invested for sample decomposition and material analysis. In 2006, another 500000 yuan was invested for core process research. The year 2007 is the year for the implementation of key technologies of the project, which mainly includes: completing the construction of the main supporting hardware conditions of the project, and simultaneously completing the preliminary technical appraisal of samples; The sample is tested in the actual industry, and the 4-year service life test is simulated by increasing the switching times; At the beginning of 2008, small batch production conditions were reached.

Pneumatic ball valves have been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as in people's daily life. Today, I'd like to share with you my knowledge of pneumatic ball valves!
