Design and development of electromagnetic control valve hydraulic coupler for scraper conveyor

Scraper conveyor is an important equipment for excavating and transporting materials in fully mechanized mining face. With the continuous development of computer technology and fluid mechanics, the research of hydraulic coupling has gone deep into all levels, not only limited to the structural characteristics of the hydraulic coupling itself, three-dimensional liquid electromagnetic calculation, three-dimensional design methods, but also involved in the optimization of the characteristic parameters of the hydraulic coupling. This topic is the technical design of the electromagnetic control valve of the hydraulic coupling, including the structural design of the main valve, the structural design of the pilot valve, and the three-dimensional modeling of the main valve. The research on the solenoid valve technology of hydraulic coupling conforms to the development concept and trend and has broad prospects
