Abstract

The invention provides a water-pressure artificial muscle joint control valve based on pressure difference and flow composite control. The water-pressure artificial muscle joint control valve comprises a steady-state pressure difference regulating valve, a first dynamic flow replenishing valve and a second dynamic flow replenishing valve which are installed inside a main valve body; the steady-state pressure difference regulating valve comprises a valve core, a valve sleeve, a No.1 sealing ring and a No.2 sealing ring; the first dynamic flow replenishing valve comprises a valve core, a valve sleeve, a liquid bridge side spring, a load side spring and a fixed liquid resistor; the second dynamic flow replenishing valve comprises a valve core, a valve sleeve, a liquid bridge side spring, a load side spring and a fixed liquid resistor; and the main valve body is provided with a main water inlet, a first main water outlet, a second main water outlet, a first main load opening and a second main loading opening. The water-pressure artificial muscle joint control valve provided by the invention solves the problems about poor control precision of artificial muscle in a water-pressure artificial muscle joint and low 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 Convenience. 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 w...
