Description
Technical field
The invention belongs to servo valve ancillary equipment fields, and in particular to a kind of servo valve outer lead outlet structure.
Background technology
Electrohydraulic servo valve is the core fine control element of servo-drive system, by the current signal conversion of milliampere grade in order to control
The high power hydraulic flow signal of servo action, has reliability and contamination resistance high requirement.
The external lead-out wire of servo valve is connected to servo mechanism, and outlet structure should be convenient for the fixation of outer lead, outer to prevent
Portion's active force directly acts on solder joint, should there is preferable protective effect to outer lead and solder joint, and outlet structure should have it is good
Good leakproofness can play servo valve moisture-proof, dust-proof effect, reduce the probability that servo valve fifth wheel occurs, and increase is watched
Take the reliability of valve.
The outlet of current servo valve largely using semi open model structure, cannot be fixed effectively for outer lead, and
Without sealing performance.
The content of the invention
It is an object of the invention to provide a kind of servo valve outer lead outlet structures, can be used in servo valve outer lead
Fixed and sealing ensures the high reliability of servo valve.
Realize the technical solution of the object of the invention：
A kind of servo valve outer lead outlet structure, it includes connection section and lead outgoing line part；The knot
Structure coupling part includes lid, socket, sealing ring and cover；The left side of lid is equipped with cylindrical outlet；Lid is connected with cover；It is set between lid and cover
There is socket, sealing ring is equipped between socket and cover；Socket is equipped with binding post；The lead outgoing line part include outer lead,
Heat-shrink tube A, heat-shrink tube B, wave prevention sleeve；The outside of outer lead is equipped with one layer of heat-shrink tube A；Outer lead is out of, lid left side cylindrical outlet
It is pierced by lid；Part of the outside of heat-shrink tube A on outer lead outside lid is equipped with one layer of wave prevention sleeve；The outside of wave prevention sleeve and lid
The outer wall of the cylindrical outlet in left side is equipped with one layer of heat-shrink tube B；Outer lead is on lid and binding post of the cover interior welds in socket.
The one section polyfluortetraethylene pipe that is equipped with package outer lead of the outer lead at jack connector column.
Binding post on the socket has 4.
It is set on cylindrical outlet outer wall on the left of the lid there are one annular groove, annular groove is equipped with silkworm silk thread, silkworm
Silk thread fastens heat-shrink tube B.
The advantageous effects of the present invention are：
A kind of servo valve outer lead outlet structure provided by the invention is gone out by will build the cylinder for being designed as complete closure
Mouth structure so that servo valve leakproofness is greatly improved；By by outer lead through using heat-shrink tube, anti-ripple before lid
Pipe, heat-shrink tube multilayer protection, avoid lead beam and friction damage occur when by covering internal, avoid certain root lead individually by
External force and solder joint is caused to be broken；Lead is fixed on by heat-shrink tube and is covered, and by circular ring slot with mulberry silk linear system
Tight heat-shrink tube avoids the relative motion of lead and lid, has isolated external force to protect solder joint, while further improved servo valve
External leakproofness improves moisture-proof, anti-dust performance.
