Abstract
The utility model relates to an all-closed explosion insulated water-proof electromagnet, which is the improvement of the explosion insulated electromagnet for the existing hydraulic valve. The all-closed explosion insulated water-proof electromagnet is composed of a casing, and the magnetic circuit assembly in the casing. The all-closed explosion insulated water-proof electromagnet is characterized in that coils in the magnetic circuit assembly and lead-out wires of the feet of a rectifier diode are directly welded in the hollow cavity of the casing, and solidified epoxy resin are filled in the hollow cavity. Compared with the prior art, the utility model cancels a connection box and a connection board, and the whole electromagnet is the totally enclosed type. The part of anti-explosion surface is reduced, the reliability of the work is improved, the anti-explosion grade is improved, water-proof ability and the foreign object-preventing ability are improved, and the external dimension is also reduced. The utility model is provided with a manual device, and the manual operation is convenient and reliable.
Description
The utility model relates to electromagnet, more particularly, is the improvement of the flame proof electromagnet used of a kind of hydraulic valve that is become by the inner magnetic circuit component groups of housing and its.
The flame proof electromagnet that hydraulic valve of the prior art is used has structure as shown in Figure 1.Mainly by housing (2) with place the magnetic circuit assembly in the housing (2) to constitute, described magnetic circuit assembly comprises coil (1), armature (8) and the push rod (9) that is connected with armature (8), with push rod (9) relative position on, a manual plunger rod (7) is arranged.The lead-out wire of described coil (1) connects rectifier diode (10).On housing (2) top is a terminal box (4), terminal box (4) internal fixation terminal block (3).Described coil (1) and rectifier diode (10) pinout enter terminal box (4) respectively with outer outgoing cable line (5), are connected on the terminal block (3).Outer outgoing cable line (5) is drawn by rubber seal (6).There is following weak point in said structure:
1, whole electromagnet has an explosion-proof a1, a2, a3, a4 at least everywhere.
2, because the existence of explosion-proof and enclosure interior cavity makes its waterproof, anti-foreign object ability extreme difference, and functional reliability and explosive-proof grade can't improve, the scope of application is very restricted.
3, for making housing (2), terminal block (3) and terminal box (4) satisfy every explosion--proof regulations (comprising leakage distance, creepage distance etc.), its overall dimension must design enough greatly.Existing flame proof electromagnet, its rated operational voltage are 380 volts, if will make its rated operational voltage bring up to 660 volts, then must enlarge the volume of housing and terminal box again.
4, coil (1) is immobilising air on every side, is unfavorable for heat radiation.
When 5, this electromagnet manually uses, be to promote plunger rod (7), not only use inconveniently, and very easily destroy the aperture of plunger rod, cause magnet to damage with certain instrument (as screwdriver etc.).
The purpose of this utility model is to avoid the deficiencies in the prior art part, dwindles the overall dimension of electromagnet to greatest extent, reduces explosion-proof facial position, improves its functional reliability and explosive-proof grade, strengthens waterproof and anti-foreign object ability to enlarge its scope of application.
The purpose of this utility model also is to set up hand gear in the outside of electromagnet, makes its manual operation easy to be reliable.
The purpose of this utility model is achieved through the following technical solutions.
The utility model is by housing and place the magnetic circuit assembly in the housing to constitute, and described magnetic circuit assembly comprises coil, armature and the push rod that is connected with armature, with the push rod relative position on a manual plunger rod is arranged.The lead-out wire of described coil is connected with rectifier diode.The lead-out wire of described coil and rectifier diode that is characterised in that of the present utility model directly is connected with the outgoing cable line in the cavity of housing, and, in cavity, be full of the epoxide resin of curing.Feature of the present utility model is that also one side is connected with manual draw bar by fulcrum in the outside of described housing, and an end of pull bar stretches to the plunger rod end.Have at the top of housing one the outgoing cable line pressure is tight, and fixed end caps.
The utility model is compared prior art owing to cancelled terminal box, terminal block, and is full of the epoxylite of curing in its cavity, has following advantage.
1, theoretically, can not be provided with explosion-proof,, be provided with 1～2 explosion-proof for guaranteeing the real work reliability.Than prior art, the big minimizing in explosion-proof facial position.
2, because behind the epoxy resin cure, have insoluble, molten characteristic and high insulative dielectric characteristic, therefore, greatly improved functional reliability, heat-sinking capability and waterproof, anti-foreign object ability, its rated operational voltage can be brought up to and exchange 50Hz 660V.
3, the utility model overall dimension reduces greatly, compact conformation.
4, because manual draw bar is set, make its convenient manual operation reliable.
Accompanying drawing 1 is the prior art structural representation.
Accompanying drawing 2 is the utility model structural representation.
Number in the figure: 1, coil, 2, housing, 3, terminal block, 4, terminal box, 5, the outgoing cable line, 6, rubber seal, 7, plunger rod, 8, armature, 9, push rod, 10, diode, 11, end cap, 12, manual draw bar, a1, a2, a3, a4, b1, b2, explosion-proof.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment;
Referring to Fig. 2, the magnetic circuit assembly places in the housing 2, after coil 1 lead-out wire, rectifier diode 10 pinouts and 5 welding of outgoing cable line, place in housing 2 upper chamber, fully be poured into whole cavitys in the housing with epoxy resin or other curable filler, comprise coil 1 surface, make its curing.Described filler can flow when possessing following characteristic: a, perfusion; B, become solid-state or semisolid after solidifying, but which kind of form no matter all can have firm adhesion with outer casing inner wall; C, high insulative dielectric and high chemical physical stability are arranged.
B1, explosion-proof composition surface, b2 two places are set, to guarantee its functional reliability.
Claims (2)
1, a kind of totally enclosed type flame proof, waterproof electromagnet, by housing (2) with place the magnetic circuit assembly in the housing (2) to constitute, described magnetic circuit assembly comprises coil (1), armature (8) and the push rod (9) that is connected with armature (8), with push rod (9) relative position on, one manual plunger rod (7) is arranged, the lead-out wire of described coil (1) is connected with rectifier diode (10), it is characterized in that:
