Description
Technical field
The present invention relates to Solenoid Valve Technology field, more particularly to a kind of safety electromagnetic valve arrangement.
Background technology
Magnetic valve (Electromagnetic valve) is the industrial equipment with Electromagnetic Control, is for controlling fluid
Automatic foundamental element, belongs to actuator, however it is not limited to hydraulic pressure, pneumatic, adjusted in industrial control system medium direction,
Flow, speed and other parameters.Magnetic valve can coordinate different circuits to realize expected control, and the precision that controls and
Flexibility can ensure.Magnetic valve has many kinds, and different magnetic valves play a role in the diverse location of control system, most often
Magnetic valve includes check valve, safety valve, solenoid directional control valve, speed-regulating valve etc..In solenoid directional control valve, reversal valve two ends
It is connected with magnetic valve, the valve rod connection of push rod outer end and reversal valve in magnetic valve, push rod the inner is connected with armature, works as magnetic valve
On coil electricity when produce magnetic field, so as to promote armature to move, armature drives push rod to promote valve element to realize reversal valve
Commutation action.In actual use, especially for some electric fields, electromagnetic valve work bad environments are long-term to locate for magnetic valve
"on" position is chronically in the coil in high temperature, high humidity state, and magnetic valve, conduction time is up to half a year, whole year, when going out
During existing failure, it is desirable to which magnetic valve can control the Vavle switching that commutates in time, to protect related executing agency, although existing magnetic valve is produced
ED=100% is all identified on product, but in actual use because ambient temperature is high, magnetic valve interior loop is led to for a long time
Electricity, the heat that packing ring is produced can not be distributed in time, so as to cause coil to damage, so as to cause serious harm.
The content of the invention
The present invention is in order to overcome electromagnetic valve coil of the prior art to be electrified for a long time, and coil radiating is bad easily to be burnt out, and is made
With unsafe not enough there is provided a kind of radiating of coil is good, it is not easy to burn out even if coil is electrified for a long time, using safer
Safety electromagnetic valve arrangement.
To achieve these goals, the present invention is adopted the following technical scheme that：

In groove, the fluid in annular cloth liquid bath enters in annular breach along intake chute, then enters spiral from the liquid feeding end of helicla flute
In groove, this kind of structure can guarantee that fluid flowing is smooth, prevent that fluid is cut off because of end in contact in armature end and preceding plug.
Preferably, the outer end of described connector is provided with pipe joint.Pipe joint can quickly and pipeline communication, very just
Just.
Preferably, provided with outer insulator, the interior insulator being located in outer insulator, described coil in described coil installation set
In annular gap between outer insulator and interior insulator, described outer insulator, interior insulator are respectively arranged at two ends with porcelain end cap.Outside
Insulator, interior insulator have good insulation and heat conductivility, on the one hand prevent coil from being contacted with extraneous band point object and short-circuit, another
The radiating of aspect energy intensifier coil.
Preferably, the periphery of the coil installation set is provided with some and axially in parallel elongated slot through holes, it is described outer
The outer circumference face of insulator is provided with some heat conduction raised lines stretched into elongated slot through hole.Heat on coil directly passes through outer porcelain
Set, heat conduction raised line are dispersed into the external world and gone, coil good heat dissipation effect.
Preferably, the top surface of described heat conduction raised line is provided with some radiating grooves.Radiating groove can strengthen heat conduction raised line top
Face and the contact area of outside air, strengthen heat dispersion.
