Abstract

The present invention provides a water pressure artificial muscle joint control valve with compound control of pressure difference and flow rate, which includes a steady-state pressure difference regulating valve, a first dynamic supplementary flow valve and a second dynamic supplementary flow valve installed inside the main valve body; The steady-state differential pressure regulating valve includes a spool, a valve sleeve, a No. 1 sealing ring and a No. 2 sealing ring; The second dynamic supplementary flow valve includes a valve core, a valve sleeve, a liquid bridge side spring, a load side spring, and a fixed liquid resistance; the main valve body is provided with a main water inlet, a first main water outlet, a second main Water outlet, first total load port and second total load port. The invention solves the problems of poor pressure control accuracy of the artificial muscle in the hydraulic artificial muscle joint and slow dynamic response speed of the joint.

Description

technical field [0001] The invention relates to the technical field of water hydraulic valves, in particular to a hydraulic artificial muscle joint control valve with combined control of pressure difference and flow. Background technique [0002] Water hydraulic technology is a technology that uses natural fresh water, sea water or tap water instead of mineral oil as the working medium of the hydraulic system. Like oil hydraulic technology, it belongs to hydraulic transmission technology. Compared with traditional oil hydraulic transmission technology, water hydraulic transmission technology has the following advantages: 1. Ecological and environmental protection, no pollution; 2. Clean and hygienic, high safety; 3. Wide range of sources and low price; 4. Maintenance and maintenance convenient. Hydraulic artificial muscle is a new type of actuator, which has the advantages of simple structure, large output force / weight ratio, and is conducive to miniaturization and light we...
