Check the technical design of the pneumatic valve

（ ） Subject of blank quality control all parts of this pneumatic valves are forgings, when forging forging process in strict accordance with the procedures and process card, strict control of forging, finish forging temperature, deformation extent and deformation velocity, according to the procedure prescribed by the cooling method for cooling. Forging products for chemical composition analysis, mechanical property test, intergranular corrosion test, microstructure analysis, through analysis, test and measurement, conform to the relevant standards.
the quality of forgings by ultrasonic inspection and liquid penetrant inspection to ensure that, in accordance with the RCC - M requirements for ultrasonic testing of forgings % and evaluation, and the all of the forging surface liquid penetrant inspection and evaluation.
　　（ ） In order to improve the quality of welding, welding of pneumatic disc and seat sealing surface welding using plasma argon arc welding process. At the same time, in order to ensure the welding quality of welding process to the process used in production.
　　（ ） Assembly test quality products not only needs high precision parts and components, more the key is how to turn these high precision components assemble high-performance products. Nuclear Sue pneumatic valve in the organization of an experienced, very skillful, composed of a number of technicians and senior technicians assembly, commissioning team, responsible for pneumatic valve assembly, debug and test, to formulate the cleaning process, the assembly process of the parts and components in the assembly and debugging on strictly, strives for perfection, to ensure the success of the pneumatic valve assembly, commissioning, and all kinds of performance testing, the indicators are in line with the requirements of design specification.
　　（ ） Process inspection quality plan is compiled for pneumatic valves, pneumatic valves to ensure that from raw material, blank inputs, machining, welding, heat treatment, nondestructive testing, cleaning, assembly, factory test, and all the type test for quality control, and get the second design institute of nuclear industry recognition and witness at the scene. Set, anticorrosive pneumatic valve manufacturing co. , LTD is a company specializing in the production of research and development sales of pneumatic valves, pumps and control equipment of collective enterprises, the main products are pneumatic diaphragm valve, regulating pneumatic valve, pneumatic valve, the cut-off pneumatic butterfly valve, check valve pneumatic pneumatic valve, pneumatic ball valve, gate valve, vacuum pneumatic valve, safety valve, American standard, British standard pneumatic valve series and other related products. In-depth development of lining fluorine rubber lining pneumatic valves, pneumatic valves and other stainless steel electric pneumatic pneumatic valve is my long-term goal for the development of the company. The IB and domestic and foreign advanced standards. With reasonable structure, exquisite workmanship, complete specifications, stable quality characteristics such as reliability and availability, to speak of sex, the three major performance, widely used in petroleum, chemical, natural gas, electric power, metallurgy, pharmacy, construction, water supply etc. And to force to develop the international market, are exported to the United States, Canada, Germany, the Middle East and other countries and regions, praised by users and trust.
