Design method of double-electric high-pressure reversing valve for deep-sea oil tree electro-hydraulic control valve group

Abstract

The invention provides a design method for a dual-power high-voltage reversing valve of an electro-hydraulic control valve set of a deep sea Christmas tree. The specific design method comprises the following four steps: determining a design scheme according to an actual use environment, checking and calculating a geometrical dimension, checking and calculating valve body operation force, and re-checking. The design method provided by the invention is reasonable, is high in calculating efficiency and precision, and a design value is more close to an actual use value, so that the reliability of the design work for the dual-power high-voltage reversing valve of the electro-hydraulic control valve set of the deep sea underwater Christmas tree is effectively improved, and therefore, the design method is beneficial for improving the stability and the reliability, in the actual use, of a valve body.

[0002] At present, in the development of deep-sea oil and gas resources, deep-sea submerged Christmas tree equipment is widely used and plays a vital role in the development of deep-sea oil and gas resources. The dual-electric high-voltage directional valve is often designed and prepared by modifying the traditional freshwater underwater double-electric high-pressure directional valve or shallow sea underwater double-electric high-voltage directional valve through empirical formulas, although it can meet the needs of deep-sea environments to a certain extent. However, there is a large error between the operating technical parameters of the double-electric high-pressure reversing valve for deep-sea oil tree and the actual use environment through design and preparation in this way, which leads to the failure of the double-electric high-pressure reversing valve in the deep sea environment. In the process of designing double-electric high-voltage reversing valves, the calculation accuracy is seriously insufficient, and the calculation efficiency is relatively low. At the same time, it is impossible to calculate the design structure obtained through calculation. Effective checking and verification will cause great trouble to the design work. Therefore, in view of this situation, it is urgent to develop a versatile and simple dual-electric high-pressure reversing valve design method to meet the actual use. needs
