[Abstract]:This subject is a product research and development project according to the market demand of the control valve products, which requires the products to reach or exceed the performance level of the same kind of foreign products. Considering all kinds of special requirements in the field of chemical engineering and the performance indexes corresponding to the control valve products, the theories and methods of integrated application of various disciplines, such as machinery, mechanics, physics, materials, etc., as well as the design of control valve products for many years by enterprises, Production experience, and different solutions to different specific conditions, so as to design and manufacture different specifications of the control valve products with higher performance, forming a special series of high performance control valve products for chemical industry. This paper first introduces the basic application of control valve in chemical engineering field, and points out that the basic requirements of control valve under different working conditions in chemical field are high leakage level, large circulation capacity, ideal flow characteristic, low basic error and stable operation. Easy to disassemble and inspect, etc. According to these performance requirements and combined with the selection and calculation of the control valve, this paper makes a thorough analysis and necessary experimental study on various factors that affect the performance of the control valve, and then puts forward the improved design of the control valve structure. The validity, feasibility and high performance of the new generation control valve products are verified by means of prototype trial production, flow test and field trial operation. According to customer feedback, the product has achieved the expected goal, perfect performance and reliable work, the ratio of performance to price is in line with the actual situation of our country's instrument and instrument industry, and has good market potential and application value.
