Problems solved by technology

The typical structure of the jet tube electro-hydraulic servo valve is a force feedback two-stage jet tube electro-hydraulic servo valve. This swinging single nozzle structure results in a longer jet pressure tube with low rigidity, which is easily affected by environmental vibration; the inertia of the moving parts is large. , slow dynamic response; the difficulty of welding and processing the feedback rod assembly and other defects are the difficulties that are difficult to solve in the current development of jet pipe valves

Abstract

The invention discloses a jet flow division valve control method and a flow division valve control double-jet-pipe electro-hydraulic servo valve. Jet flow passes through a flow division splitting ringarranged in the middle of a shell of a flow division valve body through an impulse line and is sprayed out through spray nozzles at the top ends of jet pipes on the left side and the right side on the lower side of the valve body, so that jet divided output of the double jet pipes is achieved. An oil return opening is formed in the middle of a groove on the main valve body. A valve deck with a wiring terminal is arranged outside the control valve. The valve deck is connected with the main valve body through a screw. The size of an annular gap of double cones is controlled through a double-cone valve element, so that control over oil pressure and flow is achieved. The flow division valve control double-jet-pipe electro-hydraulic servo valve has the advantages that the impulse line is shortand high in rigidity and not prone to being influenced by environment vibration; the inertia of motion components is small, and dynamic response is rapid; a feedback spring rod is low in machining difficulty and easy to install; the anti-contamination performance is good, and the reliability is high. The flow division valve control double-jet-pipe electro-hydraulic servo valve provides a novel high-reliability key servo element for the Chinese national defense and the air transport industry.

Description

technical field [0001] The invention relates to hydraulic accessory technology, in particular to a jet flow diversion valve control method and a diversion valve control double-jet tube electro-hydraulic servo valve. Background technique [0002] The jet tube electro-hydraulic servo valve is the core component of the electro-hydraulic servo control system, which is widely used in ships, aviation, aerospace and various industrial applications. The typical structure of the jet tube electro-hydraulic servo valve is a force feedback two-stage jet tube electro-hydraulic servo valve. This swinging single nozzle structure results in a longer jet pressure tube with low rigidity, which is easily affected by environmental vibration; the inertia of the moving parts is large. , Slow dynamic response; the difficulty of welding and processing the feedback rod assembly and other defects are the difficulties that are difficult to solve in the development of the current jet pipe valve.
