Abstract
The utility model relates to improvements on a small alternating-current electromagnetic valve. A copper pipe connecting structure in the prior art, which needs thicker copper material and costs much labor for process, is eliminated. A non-magnet conducting material layer is only arranged between a valve body and an electromagnetic coil, and one end of a cover is directly connected with a cover plate tightly. Thus, the utility model has the characteristics of reasonable and compact structure, less electromagnet leakage, electricity saving, no easy hot of the coil, long service life, etc.
Description
The utility model relates to a kind of alternating current electromagnetic valve, especially a kind of small-sized alternating current electromagnetic valve that is applicable to the spraying function of control industrial electric iron.
Existing alternating current electromagnetic valve kind is more.Wherein a kind of structure that is exclusively used in the small-sized alternating current electromagnetic valve of control electric iron spraying.As shown in Figure 4.It mainly is by electrician's iron of thick length and the swivel nut structural types such as (17) that the copper rod material is processed into screw mandrel (11) and matches, with electromagnetic coil (5), case (6), cover plate stubborn integrators such as (2).At this, although need not to be fastenedly connected between case and lid; Processing technology is complicated, material cost but exist, especially because of wall thickness in the copper sheathing of this structure (needing turning to be shaped on screw thread etc.).Therefore, also cause magnetic dispersion to increase suddenly, magnetic resistance increases thereupon, and electromagnetic attraction descends or required electric rating increases suddenly, makes it the electromagnetic coil quick heating, and is easily hot and burn.
The purpose of this utility model provides a kind ofly to be economized with material, and easy to process, rational in infrastructure, compact, electromagnetic leakage is little, and the electromagnetism effect improves, and power-saving, coil is difficult for hot, the small-sized alternating current electromagnetic valve of long service life.
Major scheme of the present utility model is: between described valve body and circuit coil, be provided with the non-magnet material layer; And an end of described case is provided with it the directly cover plate of Joint.Wherein said non-magnet material layer can be a coil rack; Also can be to be composited by coil rack and the thin-walled jacket layer of being located in the coil rack hole; And the latter can be the thin-walled copper sheathing, or is applied to coating layer in the coil rack hole or volume and puts within it non-magnet material thin layers such as insulating paper.The wall thickness of general described thin-walled jacket layer can be less than 1.5mm, and for example working as caliber is the copper pipe of φ 10-φ 30mm, and its wall thickness can be 0.1-1.0mm, is respectively equipped with the valve pad that seal ring and middle part have valve opening at the two ends of copper sheathing.
In addition, be located at the movable spool in the non-magnet material layer, be by the column permeability magnetic material that is provided with T type hole (as electrician's iron) formation; And on described case or cover plate, can be provided with a boss that spins mutually with the water outlet nut; Described valve body is the valve body interface phase composition that is spun mutually by valve body post and its.
Therefore, the utlity model has rational in infrastructurely, compact, economize with material, process more conveniently, electromagnetic leakage is little, and the electromagnetism effect is higher, and is power-saving, and coil is difficult for hot, and characteristics such as long service life are a kind of new and improved small-sized alternating current electromagnetic valves.
Accompanying drawing 1 is one of the agent structure schematic representation that shows that cuts open of the present utility model.
Accompanying drawing 2 is two of the agent structure schematic representation that show that cut open of the present utility model.
Accompanying drawing 3 is three of the agent structure schematic representation that show that cut open of the present utility model.
Below by embodiment, the utility model is further described.
Embodiment 1: getting one section wall thickness is 0.25mm, and caliber is the copper thin-walled jacket layer (4b) of 18mm, and close-fitting inserts in the endoporus of the coil rack (4a) that is wound with coil (5); At an end of copper thin-walled jacket layer (4b), close-fitting inserts the cylindric valve body post of being made by the turning of electrician's iron (1b).End at valve body post (1b) is provided with the internal thread that revolves mutually with valve body interface (1a), and the other end then is respectively equipped with press spring base and short-circuited conducting sleeve (7), and is provided with a water delivery duct of running through (shown in accompanying drawing 1) at axle core place.End at coil balladeur train (4a), after setting up one deck seal ring (3), insert together in the cup-shaped case (6), again at the opening of case (6), the topped cover plate (2) that is provided with boss (12), and be integral both are affixed with spot welding, copper thin-walled jacket layer (4b) then just in time stretches out from the boss (12) of cover plate (2), presses together with it.Then, at the other end of thin-walled jacket layer (4b), insert by the column permeability magnetic material constituted in be provided with the movable spool (9) in T type hole (10) and be arranged at the stage clip (8) of one end.Pad is gone up the middle part and is had the valve pad (13) of valve opening (13) again, and the upper water-out nut (15) that spins, and makes it whole water-tight.
Like this, when coil losing electricity, the movable spool of magnetic conduction (9) gos deep into to boss (12) under the effect of spring, and just in time is pressed on the valve opening (14) of valve pad (13) by the spherical top of movable spool (9), makes the water route be closed state; When the operator desires to make the iron spraying, only need Push switch, coil (5) is switched on and is produced enough electromagnetic fields, and movable spool (9) is overcome acting force of the spring and valve body post (16) adhesive mutually; Water through the T type hole (10) of water delivery duct and movable spool (9), from valve opening (13) inflow and the water spout that water outlet nut (15) revolves mutually at valve pad middle part, is finished process operation demands such as an amount of spraying promptly by valve body interface (1a).
Embodiment 2: the cover plate in the foregoing description (2) is changed the interface side that is located at valve body (1), and valve body interface and valve body post are made one.Simultaneously, boss (12) is arranged on the bottom of cup-shaped case (6), makes, case and cover plate be riveted into one (referring to accompanying drawing 2) with the sheet metal punching press.Other structure is similar, and narration is omitted.
Embodiment 3: as shown in Figure 3, adopt the higher nylon of intensity to make the electromagnetic coil skeleton among the embodiment 1 (4b), and further save the thin-walled jacket layer.Like this, the movable spool (9) of magnetic conduction is set directly in the electromagnetic coil skeleton (4a) that matches with it, and the internal diameter of boss (12) and coil rack (4a) aperture are complementary.Other structure can be same as the previously described embodiments.
