Adjustable automated manual hydraulic execution mechanism

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...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustable hand-automatic hydraulic actuator, which solves the problems of the traditional hydraulic actuator with single function, low reliability, control mode dependent on electro-hydraulic drive, and device failure in emergency situations such as power failure. Unable to work normally, seriously endangering the safe navigation of ships, it has the characteristics of compact structure, good sealing performance, high volumetric efficiency and reliability
