Abstract
The invention discloses a pressure-resisting type one-way proportion electromagnet. The pressure-resisting type one-way proportion electromagnet comprises a push rod, an armature, a guide cover, a shell, yoke iron, a spring and an adjusting screw. The push rod is installed at the front end of the armature. The spring and the adjusting screw are arranged at the back end of the armature, and the armature is installed on a bearing ring. The guide cover is of a cylindrical structure, the front section and the back section of the guide cover are made of permeability magnetic materials, a taper pot opening is formed in the front section of the guide cover, and the two sections are welded into a whole through a magnetism isolating ring. A concentric solenoid control coil is arranged between the shell and the guide cover. The yoke iron is located at the front end of the guide cover. The pressure-resisting type one-way proportion electromagnet is simple and reasonable in structure, and due to the fact that the guide cover of the cylindrical structure has enough pressure-resisting strength, the one-way proportion electromagnet can bear 35 Mpa hydraulic pressure; the push rod arranged at the front end of the armature is used for outputting power or moving, and a zero setting mechanism is formed by the adjusting screw and the spring which are installed at the back end of the armature. The armature is supported by the bearing ring so that viscous friction force can be reduced.
Description
Technical field
The present invention relates to technical field of hydraulic pressure, specifically, relate to the unidirectional proportion electro-magnet of a kind of pressure resistant type.
Background technology
Proportion electro-magnet is as the electricity of electrical-liquid control element--and mechanical switch device, its function is the current signal converting to force or displacement of Proportional Amplifer being defeated by.Proportion electro-magnet thrust is large, structure simple, and less demanding to oil, easy to maintenance, with low cost, armature chamber can make high pressure resistant structure, is most widely used electricity--mechanical transducer in electro-hydraulic proportional control technology.The characteristic of proportion electro-magnet and functional reliability, have very important impact to electro-hydraulic proportional control system and element, is one of electro-hydraulic proportional control technology critical component.Existing unidirectional proportion electro-magnet is comparatively simple due to structure, and being difficult to accomplish can be high pressure resistant.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides the unidirectional proportion electro-magnet of a kind of pressure resistant type, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
The unidirectional proportion electro-magnet of a kind of pressure resistant type, comprise push rod, armature, fairlead, housing, yoke, spring and adjustment screw, described push rod is arranged on the front end of armature, described armature rear end is provided with spring and adjustment screw, described armature is arranged on bearer ring, described fairlead is tubular structure, before and after described fairlead, two sections is permeability magnetic material, the leading portion of fairlead is provided with taper basin mouth, entirety is welded into by magnetism-isolating loop between two sections, concentric spirals tubular type control coil is provided with between described housing and fairlead, described yoke is positioned at fairlead front end.
Described bearer ring is two, is socketed in the end of armature respectively.
Described permeability magnetic material is Armco iron.
The front end of described armature is provided with banking stop in the radial direction of push rod.
The present invention is simple and reasonable, forms working gas gap in the front end of armature, and the rear end being positioned at armature forms non-working-gap, and the front end of fairlead is provided with yoke.Fairlead due to tubular structure has enough compressive resistances, can bear the hydraulic coupling of 35Mpa, and the push rod that armature front end is arranged is in order to power output or displacement, and the adjustment screw that rear end fills and spring form null setting.Armature is supported on bearer ring, to reduce viscous friction power.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is push rod, 2 is working gas gap, and 3 is coil, and 4 is non-working-gap, and 5 is adjustment screw, and 6 is spring, and 7 is armature, and 8 is bearer ring, and 9 is magnetism-isolating loop, and 10 is fairlead, and 11 is housing, and 12 is banking stop, and 13 is yoke.
Embodiment
The unidirectional proportion electro-magnet of a kind of pressure resistant type as shown in Figure 1, comprise push rod 1, armature 7, fairlead 10, housing 11, yoke 13, spring 6 and adjustment screw 5, described push rod 1 is arranged on the front end of armature 7, described armature 7 rear end is provided with spring 6 and adjustment screw 5, described armature 7 is arranged on bearer ring 8, described fairlead 10 is in tubular structure, before and after described fairlead 10, two sections is permeability magnetic material, the leading portion of fairlead 10 is provided with taper basin mouth, entirety is welded into by magnetism-isolating loop 9 between two sections, concentric spirals tubular type control coil 3 is provided with between described housing 11 and fairlead 10, described yoke 13 is positioned at fairlead 10 front end.Described bearer ring 8 is two, is socketed in the end of armature 7 respectively.Described permeability magnetic material is Armco iron.The front end of described armature 7 is provided with banking stop 12 in the radial direction of push rod 1.Form working gas gap 2 in the front end of armature 7, the rear end being positioned at armature 7 forms non-working-gap 4, and the front end of fairlead 10 is provided with yoke 13.Because the fairlead 10 of tubular structure has enough compressive resistances, can bear the hydraulic coupling of 35Mpa, the push rod 1 that armature 7 front end is arranged is in order to power output or displacement, and the adjustment screw 5 that rear end fills and spring 6 form null setting.Armature 7 is supported on bearer ring 8, to reduce viscous friction power.
During work, the magnetic circuit formed after coil electricity is divided into two-way after housing, fairlead, armature, one route fairlead front end produces inclined-plane suction to yoke, another road directly produces surface attraction by armature section to yoke, and the composite force of the two is the power output of proportion electro-magnet.The present invention is in whole stroke district, adhesive district I, effective travel district II and idle stroke district III can be divided into, in adhesive district I, working gas gap is close to zero, power output sharply rises, due to this section cisco unity malfunction, therefore structure is got rid of by the method adding non-magnetic banking stop, make armature can not move in this section; In idle stroke district III, working gas gap is larger, electromagnet power output obviously declines, although this section cisco unity malfunction, but be needs sometimes, such as in two proportion electro-magnets of direct control type proportional direction valve, when the proportion electro-magnet be energized is operated in impulse stroke district, the cold proportion electro-magnet of the other end is then in idle stroke district III; In effective travel district II, proportion electro-magnet has the displacement dynamic characteristic of basic horizontal, and the length of service area is relevant with the type of electromagnet.
