Description

Electromagnet for direct-current dry valve

Technical Field

The utility model relates to an electromagnetic drive technical field specifically provides a direct current is electro-magnet for dry-type valve.

Background

The traditional electromagnet for the direct current dry valve is, for example, the conventional model MFZ1-4.5, the mounting base of the electromagnet is a steel plate, the steel plate is firstly fixed on the electromagnet body by screws, and in addition, the mounting hole is arranged on the base and used for fixing the electromagnet. The stroke limit of one end of the iron core is realized by an end cover which is fixed on the electromagnet body by a screw.

After the end cover and the base with the structure work for a period of time, the fixing screw of the end cover and the base is easy to loosen due to the impact vibration of the frequent reciprocating motion of the iron core, so that the end cover and the base are loosened to cause faults. In addition, sometimes, the electromagnets need to be arranged and installed in a plurality of tight rows, and at the moment, because the installation base is arranged at the bottom, the fastening screw is deep in position and small in space, and the screw is very difficult to assemble and disassemble.

Disclosure of Invention

The utility model provides a to the not enough of above-mentioned prior art, provide a long service life, be convenient for the direct current dry-type electromagnet for valve of installation.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an electro-magnet for direct current dry-type valve, includes shell, lower yoke plate, upper yoke plate, guide pin bushing, iron core and coil, and lower yoke plate, upper yoke plate are fixed respectively at the both ends of shell, and the guide pin bushing passes through lower yoke plate, upper yoke plate and sets up in the shell, and the iron core cover is established in the guide pin bushing to with guide pin bushing sliding fit, the coil winding is in the guide pin bushing outside, and its characteristics are that upper yoke plate middle part is fixed with the guide pin bushing lid, and the guide pin bushing front end inserts guide pin bushing lid afterbody, and guide pin bushing lid front end.

Preferably, the iron core limiting assembly is composed of a flat pad and an inner hole retainer ring, and the flat pad is assembled at the front end of the inner hole of the guide sleeve cover and is positioned through the inner hole retainer ring.

In order to facilitate the installation of electro-magnet, can the utility model discloses the outside of electro-magnet shell sets up 3 at least column lugs that have the mounting hole, and mounting hole department is provided with mounting screw.

Preferably, the mounting screw is a half-thread screw, and an anti-falling limiting protrusion is fixed at the insertion end of the columnar lug mounting hole.

Preferably, 3-6 cylindrical lugs are uniformly distributed on the outer side of the shell.

Compared with the prior art, the utility model discloses a direct current is electro-magnet for dry-type valve has following outstanding beneficial effect:

the method comprises the following steps that (A) a flat gasket and an inner hole retainer ring are used as a movement limiting assembly at one end of an iron core, so that the iron core can still keep a stable and reliable connection state under the condition of long-time continuous high-frequency impact;

the lug and the mounting screw are arranged, so that the mounting screw is convenient to mount in any environment;

the anti-dropping limiting bulge is arranged, so that the mounting screw can be prevented from dropping and losing;

and (IV) the improvement cost is low, and the popularization and the application are convenient.
