Abstract
The utility model discloses a proportion electromagnet device, include: end terminal, coil, casing, armature, adjusting screw, inner cup, cup joint wired circle in the casing, the casing front end is provided with the end terminal, runs through being provided with adjusting screw in the casing, the adjusting screw front end passes the end terminal, and the middle part is provided with armature, and the rear end is provided with the inner cup, the end terminal rear end is provided with the spacing ring, the armature front end is provided with at a distance from the magnetic ring. Cover including the enclosing cover setting. The spring sets up between armature and inner cup. The support ring has been cup jointed on the armature. The stand pipe has been cup jointed in the end terminal and the armature outside. The utility model provides a pair of proportion electromagnet device, in effective working stroke, when a coil current timing, the invariant is held to exportable trying hard to keep, have the good linearity, less blind spot and stagnate back, step response is fast, and the frequency response is high.
Description
Technical field
The utility model relates to a kind of proportion electro-magnet device, belongs 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.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of proportion electro-magnet device.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model 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 that the utility model provides, 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 utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model 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 preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
