Abstract

The invention relates to a hydraulic valve control system of a ship. The system comprises a liquid storing groove, a pump, a directional valve and a hydraulic valve which are sequentially connected through pipelines; a stop valve is arranged on a pipeline connected between the liquid storing groove and the pump body; the pipelines at two ends of the pump body are communicated through a safety valve; the directional valve is equipped with a first arc-shaped channel and a second arc-shaped channel; the hydraulic valve comprises a valve body, and a valve element which is fixedly connected to the valve body; a piston is connected to the valve element; a first groove-shaped channel and a second groove-shaped channel are arranged on the valve element; the first groove-shaped channel is communicated with the first arc-shaped channel of the directional valve through the pipeline, and while the second groove-shaped channel is communicated with the second arc-shaped channel through the pipeline; the piston is glidingly connected with the valve element; a buffering spring is connected between the bottom surface of the valve element and the bottom part of the piston. The system is applied to the hydraulic control of the ship and has the advantages of being simple in structure, and stable and reliable to run.

Description

technical field [0001] The invention relates to a ship piping system, in particular to a control device for a valve. technical background [0002] In the field of ship deck machinery, components such as hydraulic pumps, hydraulic motors, hydraulic valves and their sealing rings and core program control systems are the core components of marine deck machinery, accounting for 20% of the structural components of deck machinery products- 40% of the proportion. Their quality and the origin of their control systems and devices play a decisive role in the technical performance and stability of deck machinery products. At present, the valves on the deck are mainly controlled by hydraulic control devices. The advantages of hydraulic control are automatic circulation and automatic overload protection, stable operation and long service life. The disadvantage of the traditional valve hydraulic control system is that the structure of the valve is relatively complicated and the control ...
