Guide electromagnetic valve is by solenoid controlled, the valve that circulation area is little.During normal position, main valve envelope valve, secondary jam pot cover lives poppet port, and valve pocket internal pressure balances.When the coil is energized, produce electromagnetic force and sucted by movable core, drive secondary valve to open, the medium in valve body leaks from poppet port, so that produce pressure difference, main valve is held up, and primary valve is opened, and solenoid valve is pathway patency just.Work as coil blackout, magnetic field dissipate, dynamic plunger return, secondary valve closure poppet port, main valve envelope valve, after valve body cavity pressure balance, valve is again in cutting out normal position.Be characterized in: the fluid pressure range upper limit compared with high, install directionless restriction, power little, can be frequently energized and energy-conservation, but fluid pressure difference condition must be met, not be suitable for liquid.
Existing electromagnetic valve structure is complicated, sealability is bad, cost is high, life-span is short, installation and maintenance bother, potential faults is many, gas flow resistance large, fifth wheel can not be discharged smoothly, easily occur that clamping stagnation and ice block up, increase the rate of fault of solenoid valve, and the safe and reliable of solenoid valve is very important, therefore the innovation of solenoid valve and improvement are very important.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of quick-fried guide electromagnetic valve, can effectively solve guide electromagnetic valve complex structure, sealability is bad, cost is high, and the life-span is short, and installation and maintenance bother, potential faults is many, gas flow resistance large, fifth wheel can not discharge smoothly, easily occur that clamping stagnation and ice block up, and increases the problem of the rate of fault of solenoid valve.
The technological scheme that the utility model solves is, comprise valve body, valve body is built with main valve, main valve central upper portion has pilot hole, there is entrance valve body side, opposite side has outlet, the pilot hole valve suitable for reading and secondary at main valve center is connected, the end opening via through holes of pilot hole is connected with outlet, form passage, main valve is connected with the sleeve on top by the first spring, cutting ferrule is had above secondary valve, cutting ferrule is connected with armature by the second spring, secondary valve, cutting ferrule, second spring and armature are assembled into and are integrally formed dynamic iron core, dynamic iron core is contained in sleeve, dynamic iron core is connected with the static iron core on top through the 3rd spring be contained on spring seat, dynamic iron core and static iron core have installed around electromagnetic coil.
The utility model novel structure is unique, and advantages of simple, easily produces, and installation and maintenance are convenient, and using effect is good, is the innovation on guide electromagnetic valve.
Accompanying drawing explanation
Fig. 1 is sectional front view of the present utility model.
Fig. 2 is the sectional view that the utility model moves iron core.
Fig. 3 is the plan view of the utility model main valve.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1 to Fig. 3, the utility model comprises valve body, valve body 1 is built with main valve 2, main valve 2 central upper portion has pilot hole 3, there is entrance 4 valve body side, opposite side has outlet 5, pilot hole 3 valve 6 suitable for reading and secondary at main valve 2 center is connected, the end opening via through holes 13 of pilot hole 3 is connected with outlet 5, form passage, main valve 2 is connected with the sleeve 9 on top by the first spring 8, secondary valve 6 has cutting ferrule 10 above, cutting ferrule 10 is connected with armature 12 by the second spring 11, secondary valve 6, cutting ferrule 10, second spring 11 and armature 12 are assembled into and are integrally formed dynamic iron core, dynamic iron core is contained in sleeve 9, the 3rd spring 14 that dynamic iron core is contained on spring seat 17 is connected with the static iron core 15 on top, dynamic iron core and static iron core 15 have installed around electromagnetic coil 16.
In order to ensure using effect, the internal diameter of described pilot hole 3 is less than the internal diameter of through hole 13; Described main valve 2 up and down in step-like 7 structures; The periphery wall of described main valve 2 bottom there is dump tank 2a; Described dump tank 2a has 6, is distributed on the periphery wall of main valve; Described sleeve 9 through screw thread spinning on main valve 2 top.
Service condition of the present utility model is, when solenoid valve is not energized, medium enters as two-way from entrance, one tunnel acts directly on main valve lower end surface, to main valve power upwards, another road is through the gap of main valve and valve body, flow through the upper-end surface that back-up ring arrives main valve, downward power is applied to main valve, because upper-end surface lifting surface area is greater than lower end surface lifting surface area, add the spring force that the spring force that transmits through dynamic iron core and sleeve compresses spring produce, make main valve seal valve, secondary jam pot cover lives poppet port, and valve pocket internal pressure balances; When the solenoid is activated, produce electromagnetic force and sucted by dynamic iron core, drive secondary valve to open, the medium in valve body leaks from pilot hole, so that produce pressure difference, main valve receives medium active force upwards, and main valve open makes gas circuit unimpeded.Work as coil blackout, magnetic force disappears, and dynamic iron core resets under spring force, the first pilot hole of secondary valve closure, main valve envelope valve, thus shut electromagnetic valve.
Design parameter of the present utility model is as follows:
Technical parameter
1, inside nominal diameter: 8mm
2, nominal pressure: 25MPa
3, working medium: air, nitrogen, rock gas
4, operating voltage: DC24V
5, operating current: 0.92A
6, interface size: G3/8 internal thread
Compared with prior art, the utility model has the following advantages:
1. structure is simply, easy to maintenance: valve body is directly connected by screw thread with sleeve, and O type ring seals, and structure is simple, and secondary valve armature is assembled into integrative-structure, makes system simple, and it is all convenient to install and keep in repair;
2 costs are low: secondary valve is connected with armature by spring, and spring can regulate armature travel, reduce armature machining accuracy, shorten the manufacture cycle, reduce costs;
3. low pressure seal is effective: have spring to be connected between main valve with sleeve, and under low voltage situations, spring force can help main valve to cut out, and prevents medium from leaking;
4. physical life is long: secondary valve is connected with there being spring between armature, and spring reduces main valve to the impact force of secondary valve, extends secondary valve working life;
5. potential faults is few: the 3rd spring is contained on spring seat, leads, prevent spring from offseting in repeating motion to spring between dynamic iron core and static iron core, the dynamic iron core stroke of impact.Main valve design adopts integral material to process, step is had up and down, and main valve circumferentially has 6 dump tanks, reduce the area of contact with valve body, the probability of happening that ice is stifled can be effectively reduced, gas flow resistance can also be reduced, and and form cavity between valve body, be easy to the eliminating of fifth wheel.In addition, increase the sectional area of main valve, main valve can be made to be subject to medium active force upwards and increase, the catching phenomenon that minimizing fifth wheel and other reasons cause, the probability that solenoid valve is broken down also reduces greatly;
6. using effect is good, and through practical application, Social and economic benef@is remarkable.
