Problems solved by technology

Among them, the cylindrical sliding joint used for fluid control often adopts the structure of single control side or double control side, which has a small pressure coefficient Kpa and a large flow pressure coefficient Kco compared with the valve structure of zero opening four sides control, and also That is to say, when the flow gain is the same, the working ability is low, which affects the driving ability of the fluid, making the sensitivity and anti-pollution ability of the valve not high
In order to have high sensitivity and anti-pollution ability, it is necessary to increase the flow rate of the valve to increase the volume and weight and reduce the dynamic quality.

Abstract

The present invention provides an electric control fluid driving equipment. Said invention includes includes the following main mechanisms: electromagnetic mechanism, driving mechanism and feedback mechanism. Said invention also provides the concrete structure of every mechanism and their connection mode, and said equipment can be used to form various proportional valves, servo valves and electromagnetic valves.

Description

technical field [0001] The invention relates to a fluid drive device, in particular to an electric control rigid angle feedback fluid drive device. Background technique [0002] The direct-acting proportional valve of the known fluid drive device uses a proportional electromagnet or a moving coil electric drive mechanism to drive the spool of the cylindrical slide valve to move in a straight line, and pushes the valve sleeve through fluid transmission to form an electronically controlled linear displacement rigid feedback. Fluid driven machinery. Among them, the cylindrical sliding joint used for fluid control often adopts the structure of single control side or double control side, which has a small pressure coefficient Kpa and a large flow pressure coefficient Kco compared with the valve structure of zero opening four sides control, and also That is to say, when the flow gain is the same, the working ability is low, which affects the driving ability of the fluid, and make...
