Abstract

The invention relates to an adjustable automated manual hydraulic execution mechanism, which comprises a controlled valve and a hydraulic executer, wherein the controlled valve and the hydraulic executer are respectively connected with a clutch type valve driving device; the hydraulic executer comprises a hollow casing of a left and right penetrating structure; an end cover is arranged at each ofthe left and right ends of the casing; an output angle regulating assembly is arranged at the outer side of the end cover; a rack is arranged in the casing; a Y-shaped sealing ring is arranged at eachof the two ends of the rack; a positioning ring is arranged at the outer side of the Y-shaped sealing ring; a baffle ring is arranged at the outer side of the positioning ring; the upper end of the rack is provided with a gear shaft engaged with the rack; a bushing is arranged at the upper end of the gear shaft; the back end of the gear shaft is connected with a connecting rod; the back end of the connecting rod is provided with a pressure measuring joint; the lower end of the casing is provided with a needle valve assembly and an upper connecting plate; a high-pressure plug is arranged on the upper connecting plate; the upper end of the casing is also provided with a safety valve, a positioning sleeve and a lower connecting plate; the lower connecting plate is fixedly connected with theclutch type valve driving device. The adjustable automated manual hydraulic execution mechanism has the characteristics that the structure is compact; the sealing performance is good; the volumetric efficiency and the reliability are high.

Description

technical field [0001] The invention relates to an adjustable manual-automatic integrated hydraulic actuator. Background technique [0002] The electro-hydraulic remote control valve is an essential control component in the ship's fluid conveying system. It is used for remote and centralized control of the on-off of the system pipeline, and realizes fast and accurate control of the fluid flow, velocity and flow direction of the pipeline. It is mainly composed of electro-hydraulic pump components, adjustable manual and automatic hydraulic actuators, and controlled valves. In the quasi-working state, the electric energy of the electro-hydraulic pump assembly is input to the two-way power output of the hydraulic medium, and the mechanical rotation of the controlled valve is realized through the hydraulic actuator. [0003] In view of the particularity of the working environment of the ship, the traditional hydraulic actuator has a single function and low reliability, and the c...
