Abstract
The utility model discloses a solenoid-type valve-used electromagnet. The solenoid-type valve-used electromagnet comprises a coil, a yoke and an armature, wherein a magnetic loop cover is arranged outside the coil; a magnetic isolating sleeve component is arranged in the coil; the front end of the armature is connected with the yoke through a spring, and the rear end of the armature is connected with a main valve in a main valve body; a return spring is arranged in the yoke; and a positioning clamp piece is sleeved outside the rear end of the armature. In the utility model, the return spring in the yoke enables the yoke to move in the magnetic shielding component, so that the effective motion stroke of the electromagnet is improved; the solenoid-type valve-used electromagnet is particularly suitable for the manufacturing and production of low-power long-stroke solenoid valves; and the positioning clamp piece is used to limit the distance between the yoke and the armature in the initial position, so as to ensure a smaller initial stroke and improve the working frequency of the electromagnet.
Description
Technical field
The utility model relates to a kind of electromagnetic actuator, is specifically related to a kind of helix tube type valve control electromagnet.
Background technology
Solenoid electromagnet is the common action executive component of (as relay, electromagnetically operated valve etc.) on a large amount of electrical equipment that use, and mainly is made up of parts such as coil, yoke, armature.Traditional electromagnet is that yoke is fixed in its magnetic shield, and electromagnet is under "on" position, and armature moves according to the needed stroke of valve.Owing to fixed yoke, distance when original position between yoke and the armature just increases with the increase of electromagnetically operated valve stroke, particularly under the condition of work of small-power, big stroke, traditional electrical magnet just might occur can't sticking, can not open the phenomenon of the main valve of required unlatching.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of helix tube type valve control electromagnet is provided.
A kind of helix tube type valve control electromagnet that the utility model provides comprises coil, yoke, armature, described coil be provided with outward the magnetic loop cover, in be provided with the magnetic shield assembly, described armature front end is connected with yoke by spring, and the rear end joins with the main valve that is arranged in the main valve body; Be provided with back-moving spring in the described yoke, described armature rear end outer cover is provided with the location fastener.
The utility model can make yoke move in the magnetic shield assembly by being arranged on the back-moving spring in the yoke, has improved the effective travel that electromagnet moves, and especially being useful in needs in the electromagnetically operated valve manufacturing of small-power, the big stroke production.Distance when placing restrictions on original position with the location fastener between yoke and the armature has guaranteed less initial stroke, can improve the operating frequency of electromagnet.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
Embodiment 1
Referring to Fig. 1, a kind of helix tube type valve control electromagnet that the utility model provides comprises coil 1, yoke 2, armature 3, described coil 1 is outer be provided with magnetic loop cover 4, in be provided with magnetic shield assembly 5, described armature 3 front ends are connected with yoke 2 by spring, and the rear end joins with the main valve 7 that is arranged in the main valve body 6;
Be provided with back-moving spring 8 in the described yoke 2, can in magnetic shield assembly 5, move with the signal of telecommunication of electromagnet;
Described armature 3 rear end outer cover are provided with location fastener 9, and location fastener 9 has guaranteed that electromagnet has an initial gap between cold state lower yoke 2 and armature 3, and yoke 2 is inhaled in aggregates mobile in magnetic shield assembly 5 with armature 3 mutually when energising.
Embodiment 2
During work,
Obtain the signal of telecommunication of rated voltage when coil 1 after, the magnetic loop of being made up of magnetic loop cover 4 and magnetic shield assembly 5 has just produced electromagnetic force, under the driving of electromagnetic force, armature 3 moves in the middle of coil 1, inhale mutually with yoke 2, and continue after back-moving spring 8 thrusts in having overcome yoke 2 to move, till magnetic field reaches capacity state.At this moment, the main valve 7 in main valve body 6 is also opened thereupon, and in check fluid is from the outlet ejection.
When coil 1 outage, electromagnetic force hour, yoke of being made by soft magnetic material 2 and armature 3 are pushed main valve to closed condition rapidly under the thrust of back-moving spring 8.Yoke 2 and armature 6 return to original position, and by location fastener 7 strict controls initial stroke between the two, electromagnet is got back to reset condition.
Claims (1)
