Abstract
The utility model discloses explosion-proof electromagnet, belonging to the field of electromechanical equipment. The device comprises a coil, armature, a lower yoke plate, an outer sleeve assembly and an outgoing line, wherein the part of the outer sleeve assembly on the outgoing line is provided with an opening by adopting an inner thread; an outer coupler is in threaded connection with the outer sleeve assembly; a sealing sleeve is arranged in the outer coupler and a steel sleeve is pressed on the sealing sleeve; a locking nut is fixed with the outer coupler through the thread and tightly presses the steel sleeve; and the outgoing line is leaded out of the outer part of the electromagnet through holes in the middles of the sealing sleeve, the steel sleeve and the locking nut. The explosion-proof electromagnet has the advantages of simple structure and convenience for installation, and can be well applied to automation of field realizing equipment with explosive gas.
Description
Technical field
The utility model relates to a kind of electromagnet, and particularly a kind of electromagnet that uses under can quick-fried environment belongs to the electromechanical equipment field.
Background technology
Along with popularizing of present industrial automation, also more and more widely also improve the requirement of electromagnet day by day the application scenario of electromagnet; Under many occasions, for example all possibly there is or reveals flammable explosive gas in the production of mine, semicon industry, chemical industry, under the situation that produces blast; Control requirement and reliability to industrial electrical equipment are more strict, so at the electromagnet that occasion need have explosion-proof performance of installing and using of many equipment, in order to realize explosion prevention function; Usually adopt explosion-proof, explosion-proof lamp in the design of electromagnet with in making; This type electromagnet has played explosion-proof effect to a certain extent, often connects through welding and screw mode like the outgoing cable of flame proof electromagnet in the past, and not only installation process is cumbersome; And; The long-time use caused the corrosion of welding portion easily, influence the useful life of electromagnet but in practical application, also exists poorly sealed close, lead-out wire to be prone to various unreliable factors such as loosening generation danger.
Summary of the invention
The utility model is for providing a kind of anti-explosion is electromagnetic iron, and such electromagnet has higher explosion-proof reliability.
A kind of anti-explosion is electromagnetic iron that the utility model provided; Comprise coil, armature, following yoke plate, outer jacket member, lead-out wire, outer jacket member adopts internal thread perforate, outer coupling and outer jacket member thread connection at the position of lead-out wire; Sealing shroud is arranged in the outer coupling; Steel bushing is pressed in above the sealing shroud, and steel bushing is fixed and compressed to locking nut through screw thread and outer coupling, and lead-out wire is drawn the electromagnet outside through the hole in the middle of sealing shroud, steel bushing, the locking nut; Described lead-out wire adopts explosion-proof line, between its external sleeve assembly and the following yoke plate sealing ring is set.
A kind of anti-explosion is electromagnetic iron that the utility model provided; Simple in structure, easy for installation, it is loosening in use to be difficult for producing lead-out wire; Reduce the probability that produces the ignition source, can be applied to the automation of the equipment of realizing on the equipment of electromagnet of damp occasion preferably.
Description of drawings
Accompanying drawing 1 is the sketch map
of the utility model.
Embodiment
Shown in accompanying drawing, install coil 1 and armature 2 and outer jacket member 4 in order, between yoke plate 3 and the outer jacket member 4 sealing ring 10 is being set down; Electromagnet lead-out wire 5 from the perforate of outer jacket member 4 one draw, female thread structure is adopted in perforate, outer coupling 6 and outer jacket member 4 thread connection; Outer coupling 6 can adopt pyramidal structure; Up big and down small, sealing shroud 7 is arranged in the outer coupling, and sealing shroud 7 adopts the fluorubber material; Steel bushing 8 is pressed in above the sealing shroud 7; Steel bushing 8 is fixed and compressed to locking nut 9 through screw thread and outer coupling 6, and lead-out wire 5 is drawn the electromagnet outside through the holes in the middle of sealing shroud 7, steel bushing 8, the locking nut 9, and described lead-out wire 5 adopts explosion-proof line.
The electromagnet lead-out wire adopts the flame proof line in the explosion-proof design of the utility model, and the leading-out terminal to the flame proof line has adopted the sealing shroud of fluorubber material to seal simultaneously, adopts thread connecting mode to connect with steel bushing and locking nut; Easy to connect; Good seal performance, explosion insulation performance is good, has strengthened sealing between its external sleeve assembly and the following yoke plate simultaneously; Improved the explosion-proof performance of electromagnet, this utility model product is applicable to there being damp to need the equipment of electromagnet.
The above is the preferred implementation of the utility model; Any those of ordinary skill in the art can be well understood to; Can carry out various variations and modification not breaking away under the utility model technical scheme scope; All technology contents according to the utility model all belong to the scope of the utility model technical scheme to any simple modification, equivalent variations and modification that above embodiment did, and the utility model execution mode of also not being subject in the specification to be given an actual example.
