Abstract
The utility model relates to an electromagnetic valve based on the technical proposal that: a water inlet joint and a water outlet joint are screwed together to form a valve; a moveable valve core is arranged inside a hollow column chamber of the valve; a water passage is arranged along the outer circumference of the valve core; the central axes of the water inlet joint and the water outlet joint of the valve core are at the same horizontal line. The interface of the water outlet joint and the valve core is a conical surface; an electromagnetic coil is sheathed on the outside of the water inlet joint or the water outlet joint; a permanent-magnet is fixed on the valve core; the electromagnetic coil is connected with a DC power source and controls the valve through a control switch.
Description
One, described field: the utility model relates to a kind of solenoid valve.
Two, background technique: existing solenoid valve is the spool that vertical water-in and water-out joint is installed in the cylindrical cavity of valve body, the outside at valve body is with electromagnetic coil, on spool, be fixed with permanent magnet, electromagnetic coil is connected with DC electrical source, by the open and close of control switch control valve.The open and close of this solenoid valve all needs to realize that by power supply control it is not tight to occur valve closing easily, the phenomenon of wasting water.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned technical problem that exists at existing solenoid valve, and a kind of Through solenoid valve by the water pipeline pressure automatic cut-off is provided.
Realize that the technological scheme that above-mentioned purpose adopts is: being threaded by a water supply connector and a water output connector constitutes a valve body, and movably spool is installed in the cylindrical cavity of valve body, and the outer periphery of spool is provided with water channel.The medial axis of spool and water supply connector and water output connector is at same horizontal line, water output connector is that the plane cooperates with the junction plane of spool, the outside at water supply connector or water output connector is with electromagnetic coil, on spool, be fixed with permanent magnet, electromagnetic coil is connected with DC electrical source, and the interaction by the permanent magnet on control switch control electromagnetic coil and the spool, the unlatching of realization valve.Permanent magnet loses electromagnetic action behind the deenergization, promotes combining of spool and water output connector by siphon pressure, the closing of realization valve.Here miscellaneous part is nonmagnetic substance except permanent magnet.
Such scheme can also be improved to: spool is fixed with sealing gasket with the connecting part of water output connector and combines with the water output connector plane, and another side has protruding bolt, and permanent magnet is fixed by nut after being inserted in protruding bolt.On the junction plane of nut and water supply connector, be provided with projection, make between spool and the water supply connector and form passage.By protecting cover electromagnetic coil is being sealed on the valve body around the electromagnetic coil and between the valve body.
Solenoid valve of the present utility model has adopted the straight-through mode of structure of spool and water-in and water-out joint, thereby has simple in structurely, easy to use, has particularly overcome closed condition and has occurred leakage problem easily, has automatic closing function.The polarity that changes electromagnetic coil simultaneously can realize the two-way control of open and close.
Four, description of drawings: Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of circuit structure connection diagram of the present utility model.
Five, embodiment:
Contrast Fig. 1, being threaded by a water supply connector 6 and a water output connector 2 constitutes a valve body, and movably spool 9 is installed in the cylindrical cavity of valve body, and the outer periphery of spool 9 is provided with water channel.The medial axis of spool 9 and water supply connector 6 and water output connector 2 is at same horizontal line, water output connector 2 is that the plane cooperates with the junction plane of spool 9, connecting part at spool 9 and water output connector 2 is fixed with sealing gasket 3, and another side has protruding bolt, and permanent magnet 4 is fixed by nut 5 after being inserted in protruding bolt.The outside at water output connector 2 (also can in water supply connector 6) is with electromagnetic coil 1, on spool 9, be fixed with permanent magnet 4, electromagnetic coil 1 is connected with DC electrical source, and the interaction by the permanent magnet 4 on control switch control electromagnetic coil 1 and the spool 9, realizes the unlatching of valve.Permanent magnet 4 loses electromagnetic action behind the deenergization, promotes combining of spool 9 and water output connector 2 by siphon pressure, the closing of realization valve.On the junction plane of nut 5 and water supply connector 6, be provided with projection 7, make between spool 9 and the water supply connector 6 and form passage.Between nut 5 and permanent magnet 4, be added with pad 8, to improve the stability of spool 9.By protecting cover 10 electromagnetic coil 1 is being sealed on the valve body around the electromagnetic coil 1 and between the valve body.Here be nonmagnetic substance except permanent magnet 5 miscellaneous parts.
Solenoid valve of the present utility model has adopted spool and the straight-through mode of structure of water-in and water-out joint, has automatic closing function.The polarity that changes electromagnetic coil simultaneously can realize the two-way control of open and close.
