Description
Technical field
The present invention relates to Solenoid Valve Technology field, a kind of discharging type magnetic valve is particularly related to.
Background technology
In recent years, magnetic valve is had been widely used in rail control engine, at present, in conventional solenoid valve, and work is situated between
Matter enters from valve inlet under a certain pressure, and produces certain actuating pressure and act on valve element；Palpus gram during valve opening
Operation medium power and spring force are taken, VOP is larger, required electromagnetic attraction is larger, and coil windings are larger, finally
Cause that valve volume is big, weight big, the response time is long.
In some high-pressure high-flow fields, conventional solenoid valve suffers from certain volume and limited with weight.
The content of the invention
There is provided it is an object of the invention to solve the problems such as above-mentioned conventional high-pressure big flow magnetic valve volume is big, weight is big
Magnetic valve with unloading function, it is small using small volume of the present invention, lightweight, unlatching electromagnetic attraction, the big stream of high pressure can be met
Measure the requirement of magnetic valve.
In order to solve the above technical problems, embodiments of the invention provide a kind of discharging type magnetic valve, including valve body, valve element group
Part and magnet assembly, the core assembly is in the valve body, and the magnet assembly is fixed on valve body upper end, the magnet assembly by
Valve pocket, magnetism-isolating loop and magnet extremity piece composition, the valve pocket are fixed on valve body upper end, and the magnetism-isolating loop is fixed on valve pocket upper end, institute
State magnet extremity piece to be fixed on magnetism-isolating loop, described cover plate is fixed on magnet extremity piece, lead between the core assembly and valve body
Cross on the outside of O-ring seals sealing, the magnet assembly and be socketed with case, coil bone is provided between the case and magnet assembly
Coil is socketed with frame, the coil rack.
Preferably, the valve pocket is provided with spring base with valve body junction, it is provided between the core assembly and spring base
Spring.
Preferably, the core assembly includes nonmetallic sealing block, trip bolt, pad and armature, it is described nonmetallic
Sealing block is fixed on armature by pad and trip bolt；Sealed between armature and valve pocket by O-ring seals.
Preferably, be provided with the middle of the trip bolt on through hole, the armature be communicated with to valve export, armature with
The centre bore and inclined hole in gap between magnet extremity piece.
Preferably, the valve pocket, magnetism-isolating loop and the integrally welded structure of magnet extremity piece.
Preferably, the O-ring seal internal diameter is identical with the valve body cutting edge internal diameter of valve body lower end.
The above-mentioned technical proposal of the present invention has the beneficial effect that：Armature is equal to O-ring seals sealing surface sealing radius
Valve body radius of edge, therefore working medium inlet pressure cancels out each other in the active force produced by valve element both sides；Valve element not by
In the case of operation medium power, valve opening only needs to overcome certain spring force, therefore the Opening pressure of valve is smaller, with
In the case of the identical aperture of general solenoid valve, required electromagnetic attraction is smaller, coil windings are smaller so that valve mechanism is compact, weight
Amount is light, response is fast；Because valve element is not by the active force of working media, valve opening only needs to overcome certain spring force, therefore valve
Door can adapt in the larger field of inlet pressure；Because valve element is not by the active force of working media, valve opening only needs to overcome
Certain spring force, therefore the increase of valve opening scope, valve flow are bigger.
