Abstract
The invention discloses a proportional electromagnet device, which comprises a pole shoe, a coil, a shell, an armature, an adjusting bolt and an inner cover, wherein the coil is sleeved with the shell; the pole shoe is arranged at the front end of the shell; the adjusting bolt is arranged in the shell in a penetrating manner; the front end of the adjusting bolt passes through the pole shoe; the armature is arranged in the middle part; the inner cover is arranged at the rear end; a limiting ring is arranged at the rear end of the pole shoe; a magnetic isolating ring is arranged at the front end of the armature; an outer cover is arranged on the inner cover; a spring is arranged between the armature and the inner cover; a support ring sleeves the armature; and a guide pipe sleeves the outer sides of the pole shoe and the armature. The proportional electromagnet device disclosed by the invention can keep output force constant within an effective working stroke when the current of the coil is fixed, and has good linearity, relatively small dead zone and hysteresis, fast step response and high frequency response.
Description
Technical field
The present invention relates to a kind of proportion electro-magnet device, belong to proportioning valve accessory technical field.
Background technology
At present, for the engineering mechanical device that some automaticities are higher, as full hydraulic excavator, concrete mixer etc., often require the parameter to system, as pressure, flow carry out continuous stepless control.Electro-hydraulic proportional valve is the quasi-representative control valve meeting this requirement.
In current ratio valve, very important accessory is proportion electro-magnet, if proportion electro-magnet suction exports cannot meet spring force curve, will bring the inaccurate problem of ratio pressure regulating valve.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of proportion electro-magnet device.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of proportion electro-magnet device, comprise: pole shoe, coil, housing, armature, adjustment screw, inner cap, coil is socketed with in described housing, housing forward end is provided with pole shoe, run through in housing and be provided with adjustment screw, described adjustment screw front end is through pole shoe, and middle part is provided with armature, and rear end is provided with inner cap; Described pole shoe rear end is provided with spacing ring; Described armature front end is provided with magnetism-isolating loop.
Also comprise enclosing cover, cover in described enclosing cover is arranged on.
Also comprise spring, described spring is arranged between armature and inner cap.
Also comprise support ring, described armature is socketed with support ring.
Also comprise guide pipe, outside described pole shoe and armature, be socketed with guide pipe.
Preferably, described armature adopts silicon steel material.
Beneficial effect: a kind of proportion electro-magnet device provided by the invention, in effective impulse stroke, when coil current one timing, exportable try hard to keep hold constant; There is the good linearity, less dead band and hysteresis; Step response is fast, and frequency response is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of proportion electro-magnet device, comprise: pole shoe 1, coil 2, housing 3, armature 4, adjustment screw 5, inner cap 6, coil 2 is socketed with in described housing 3, housing 3 front end is provided with pole shoe 1, runs through being provided with adjustment screw 5 in housing 3, and described adjustment screw 5 front end is through pole shoe 1, middle part is provided with armature 4, and rear end is provided with inner cap 6; Described pole shoe 1 rear end is provided with spacing ring 7; Described armature 4 front end is provided with magnetism-isolating loop 8.
Also comprise enclosing cover 9, described enclosing cover 9 is arranged on inner cap 6.
Also comprise spring 10, described spring 10 is arranged between armature 4 and inner cap 6.
Also comprise support ring 11, described armature 4 is socketed with support ring 11.
Also comprise guide pipe 12, outside described pole shoe 1 and armature 4, be socketed with guide pipe 12.
Concrete occupation mode is as follows: during use, produces magnetic field after coil electricity, and due to the existence of magnetism-isolating loop, make magnetic line of force major part by armature, air gap and pole shoe, pole shoe produces suction to armature.Coil current one timing, suction size is because pole shoe and armature residual gap are apart from different and change.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
