Working Principle

The paper introduces the working principle of a logging instrument, and according to the working principle and instrument’s function of two-way hydraulic control valve. Facing to the key problems of process equipment in the actual service and workflow, the structure of value was designed and optimized. At the same time, the logging instrument with a dual-channel and two-way hydraulic control valve is designed and processed. Meanwhile, we build an experimental platform and make the experiment according to principle of the instrument. The results show that the design of this dual-channel and two-way hydraulic control valve logging instrument met the work requirements, and it has high reliability in oil exploration, which could be promoted and used in logging areas.

The Relationship

Purpose The purpose of this paper is to study the flow characteristics of damping control valve of shock absorber, and obtain the minimum driving current required under different working conditions. Design/methodology/approach Based on the simplified model of the internal structure of damping control valve and the theory of fluid mechanics, the mathematical model of the damping control valve driving current under rated load is established. The test bench was designed to study the relationship between flow characteristics and driving current of the damping control valve. Findings The results show that the minimum driving current of switching and flowrate show a linear relationship and the minimum current required for the 4-1 switching is the largest that means the minimum current as long as meets the 4-1 switching to meet the needs of all levels switching. Originality/value These results of the theoretical and experimental study provide a reliable guide and reference for the design and application of damping control valve.
