Description
Technical field
The present invention relates to Solenoid Valve Technology field, refer to a kind of discharging type solenoid valve especially.
Background technique
In recent years, solenoid valve has been widely used in rail control motor, and at present, in conventional solenoid valve, working medium enters from valve inlet under a certain pressure, and produces certain actuating pressure and act on spool; Must overcome operation medium power and spring force during valve opening, VOP is comparatively large, and required electromagnetic attraction is comparatively large, and coil winding is comparatively large, finally causes that valve volume is large, weight large, and the response time is long.
In some high-pressure high-flow field, conventional solenoid valve is often subject to certain volume and weight limits.
Summary of the invention
The object of the invention is to solve the problems such as above-mentioned conventional high-pressure large discharge solenoid valve volume is large, weight is large and the solenoid valve with unloading function is provided, utilize volume of the present invention little, lightweight, open electromagnetic attraction little, the requirement of high-pressure high-flow solenoid valve can be met.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of discharging type solenoid valve, comprise valve body, mangetic core assembly and magnet assembly, described mangetic core assembly is located in valve body, described magnet assembly is fixed on valve body upper end, described magnet assembly is by valve pocket, magnetism resistent ring and magnet extremity piece composition, described valve pocket is fixed on valve body upper end, described magnetism resistent ring is fixed on valve pocket upper end, described magnet extremity piece is fixed on magnetism resistent ring, described cover plate is fixed on magnet extremity piece, sealed by O-ring seals between described mangetic core assembly and valve body, case is socketed with outside described magnet assembly, coil rack is provided with between described case and magnet assembly, described coil rack is socketed with coil.
As preferably, described valve pocket and valve body joint are provided with spring seat, are provided with spring between described mangetic core assembly and spring seat.
As preferably, described mangetic core assembly comprises nonmetal sealing block, fastening screw trip bolt, liner and armature, and described nonmetal sealing block is fixed on armature by liner and fastening screw trip bolt; Sealed by O-ring seals between armature and valve pocket.
As preferably, is provided with through hole in the middle of described fastening screw trip bolt, described armature is provided with and is communicated to valve export, the center hole in gap and inclined hole between armature and magnet extremity piece.
As preferably, described valve pocket, magnetism resistent ring and the integrally welded structure of magnet extremity piece.
As preferably, described O RunddichtringO internal diameter is identical with the valve body cutting edge internal diameter of valve body lower end.
The beneficial effect of technique scheme of the present invention is as follows: armature and O-ring seals sealing surface seal radius and equal valve body radius of edge, and the active force that therefore working medium inlet pressure produces in spool both sides is cancelled out each other; When spool is not by operation medium power, valve opening only needs to overcome certain spring force, and therefore the cracking pressure of valve is less, in aperture situation identical with general solenoid valve, required electromagnetic attraction is less, coil winding is less, makes valve mechanism compact, lightweight, response is fast; Because spool is not by the active force of working medium, valve opening only needs to overcome certain spring force, and therefore valve can be adapted to the larger field of inlet pressure; Because spool is not by the active force of working medium, valve opening only needs to overcome certain spring force, and therefore valve opening scope increases, and valve flow is larger.
