Check valve in process design

      Process design

    (1).Quality control of all parts of the valve body blank are forging,forging in strict accordance with the forging process planning and process card, strictly control the initial forging temperature, forgingtemperature, deformation degree and deformation velocity, coolingby cooling process rules. Analysis of chemical composition analysis,mechanical property test, intergranular corrosion test,metallographic structure of forging products, through analysis, test and measurement, are in line with the corresponding standard.

      The quality of forgings by ultrasonic and liquid penetrant testing to ensure that, in accordance with the requirements of 100% RCCMon forgings ultrasonic testing and evaluation, and all surfaces of theforgings for liquid penetrant inspection and evaluation.

       (2).In order to improve the quality of surfacing welding, sealing surface surfacing valve and seat of the plasma argon arc weldingprocess. At the same time, to ensure the welding quality, thewelding process in the production of re process assessment.

      (3).Assembly test quality products not only require high precisionparts, the more important is how to use these high precision parts are assembled into a product with high performance. The Sufaorganized a team of experienced, skilled technicians and senior technicians, by more than the composition of the assembly,commissioning team, responsible for the valve assembly,debugging, testing, the cleaning process, assembly process of parts in assembly and debugging, in the strict, excellence, to ensure that the valve assembly, debugging success, and all kinds of performance test was carried out, the indicators are in line with the requirements of the design task.

     (4).The process inspection for quality plan to ensure that the valveto the valve, from raw material, blank, machining, welding, inputheat treatment, nondestructive testing, cleaning, assembly, test and the test of all types are quality control, and obtains the approvaland the second research and Design Institute of nuclear industrywitness. Shanghai Linuo Valve Manufacturing Co., Ltd. is a groupenterprise specialized in R & D and production and sales of various types of valves, pumps and control equipment, the main products are valve, regulating valve, butterfly valve, globe valve, ball valve,check valve, gate valve, relief valve, safety valve and American Standard, British standard valve series and other related products.
