Abstract

The invention provides a hydraulic integrated valve block for an aviation electrostatic hydraulic actuation system, which includes a valve block body, an oil pipe channel and an orifice structure. B-spline curve forming is adopted, and the additive manufacturing process is used to form the valve block at the same time; the orifice structure is formed together with the valve block and the oil pipe channel by the additive manufacturing process, and the orifice structure is a circular orifice structure; the oil pipe channel The connection mode with the orifice structure is tangential and smooth connection; the direction of the reversing part of the oil pipe channel changes smoothly, without a right-angle structure; the orifice structure is a straight hole, and its inner wall is perpendicular to the surface of the valve block. The invention adopts the additive manufacturing forming process to replace the traditional process forming the valve block and its internal flow channel structure, effectively solves the technical problems such as large pressure loss in complex pipelines and complicated design process, and has the advantages of small pressure loss, simple preparation and wide application range advantages, and effectively reduce the weight of the hydraulic integrated valve block.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to a hydraulic integrated valve block for an aviation electro-hydrostatic actuation system. Background technique [0002] The hydraulic valve is an automation component commonly used in the industry through pressure control. When the hydraulic valve is working, it is mainly controlled by the internal pressure oil. It can control the relatively long-distance water and electricity pipelines by cooperating with the pressure distribution valve. At present There are two main types that are common on the market, direct-acting and pilot-operated. The hydraulic valve is mainly used to control the pressure and flow direction of the liquid in the hydraulic system. When the hydraulic valve is controlled, it can control the pressure and flow direction more accurately. The working principle of the hydraulic valve is to use the relative movement of the spool in the valve body to c...
