Abstract

The invention provides a voice coil motor direct-driven long chute valve port water hydraulic throttle valve, comprising a voice coil motor, a throttle body, a left valve sleeve, a middle valve sleeve, a right valve sleeve, a valve core and a connection system; The voice coil motor includes a coil mover and a magnetic stator, the magnetic stator and the second connecting block are respectively fixedly installed on the left and right sides of the first connecting block, and the throttle body is fixedly installed on the second connecting block. The right side of the connection block, the third connection block is fixedly installed on the right side of the throttle body; the middle part of the throttle body is provided with a blind hole I; the left valve sleeve, the middle valve sleeve, the The right valve sleeve and the valve core are both arranged in the blind hole I; the left valve sleeve, the middle valve sleeve and the right valve sleeve are respectively sleeved on the outside of the valve core, and are connected with the blind hole I. Hole I is clearance fit; the middle part of the valve core is provided with a slot with an inclined plane. The technical problems such as the poor dynamic characteristics of the spool of the water hydraulic throttle valve and the small displacement stroke of the spool are solved.

Description

technical field [0001] The invention relates to the technical field of water hydraulic valves, in particular to a water hydraulic throttle valve directly driven by a voice coil motor with a long chute. 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. Valve is one of the core elements of hydraulic transmission system, and its working performance has a great influence on the whole system. Compared with the mature oil-hydraulic transmission techn...
