Problems solved by technology

When overcoming the negative torque condition, the external negative torque is consistent with the rotation direction of the rudder blade, and the hydraulic slide valve moves frequently according to the oil pressure changes in and out of the steering cylinder. The system tends to stabilize for a long time a

Abstract

A plug-in type valve special for an electro-hydraulic proportional steering engine is composed of a valve body, a pilot slide valve, an armature pushing rod, a proportional electromagnet, a pilot reset spring, a pilot valve end cap, a plug-in valve body, a plug-in valve element, a plug-in valve reset spring, a plug-in valve cap, a shuttle valve element and a shuttle valve base. The valve body is internally composed of a main oil channel and a pilot control oil channel, the main oil channel is composed of a left main valve hole, a right main valve hole, the plug-in valve body, the plug-in valve element, the plug-in valve reset spring, the plug-in valve cap, the shuttle valve element and the shuttle valve base, the pilot control oil channel is formed by the cooperation of a pilot valve hole and the pilot slide valve, the pilot reset spring is arranged at one end of the pilot slide valve and makes contact with the pilot valve end cap, the armature pushing rod of the proportional electromagnet is at the other end of the pilot slide valve and makes contact with the pilot slide valve, and the proportional electromagnet is connected with the valve body through a bolt for performing linear control over a control oil channel and then performing dynamic adjusting on the apertures of the plug-in valve body and the plug-in valve element of the main oil channel.

Description

technical field [0001] The invention belongs to the field of steering gear, and in particular relates to a special valve for a marine plug-in electro-hydraulic proportional steering gear. Background technique [0002] The valve-controlled marine hydraulic steering gear is generally composed of a pump group, a steering mechanism, a control valve group, a fuel tank and its connecting pipelines. The special valve for the steering gear is the core of the control valve group, and the movement of the steering gear is controlled by the special valve for the steering gear. To adapt to normal steering, anti-wave impact, negative torque conditions. [0003] At present, the special valve for the steering gear used in the known valve-controlled marine hydraulic steering gear to control the rudder steering is a hydraulic control balance valve, which is suitable for normal steering and overcoming negative torque conditions. When overcoming the negative torque condition, the external nega...
