Abstract
The utility model discloses a double-control solenoid valve which comprises a coil and a solenoid valve core, wherein a movable magnet vane is arranged above the coil and the solenoid valve core, a permanent magnet is fixedly arranged above the magnet vane; a movable permanent magnet is arranged above the coil and the solenoid valve core, and new lifting control on the solenoid valve can be realized by moving the permanent electromagnet. As the control of the solenoid valve on the valve core is realized by double-loop control of a common coil electromagnetic field and a magnetic field generated by the permanent magnet, normal switching-on and use of the solenoid valve in the condition that a main circuit is powered off can be realized. The double-control solenoid valve has unique emergency significance in certain special occasions. If powering off of a main power grid caused by an earthquake and the like is realized, the solenoid valve can be conveniently switched on.
Description
Technical field
The utility model relates to solenoid valve, is specially a kind of double control electromagnetic valve.
Background technique
Solenoid valve is the valve that moves with electromagnet control valve core, is used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system.Solenoid valve is to control with the effect of electromagnetism, and main control mode is controlled by relay.Like this, solenoid valve can cooperate different circuit to realize the control of expecting, and the precision and the flexibility of control can both guarantee.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system, and the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc.In all solenoid valves, the overwhelming majority is to use Ac to become DC control, in case outage, a lot of solenoid valves can't manual unlocking, so when the design pipeline, the general manual valve that also designs a parallel connection on the next door of solenoid valve uses in order to current failure emergency.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provide a kind of can electronic control manual a kind of double control electromagnetic valve of control switch again.
Technical solution adopted in the utility model is: a kind of double control electromagnetic valve, comprise coil and valve core of the electromagnetic valve, and the magnetic isolation board that can remove is arranged above coil and valve core of the electromagnetic valve, the upper fixed of magnetic isolation board has permanent magnet.
The described magnetic isolation board of removing is manually control.The described magnetic isolation board of removing is the control of dry battery power wireless remote.Promptly utilize dryelement cell to provide the micro motor of power supply to drive, be aided with telecontrol again and move magnetic isolation board.
A kind of double control electromagnetic valve of another kind of implementation comprises coil and valve core of the electromagnetic valve, and movably permanent magnet is arranged above coil and valve core of the electromagnetic valve.Promptly the way by mobile permanent magnet realizes the lifting control new to solenoid valve.
A simple way is, there is axis hole in one side portion of described permanent magnet, and shaft hole sleeve is connected in the rotating shaft, and this rotating shaft departs from the electromagnetic valve core central shaft.By rotating permanent magnet, make the magnetic field center of permanent magnet with battery valve center spool axle is overlapping or skew, to reach the purpose of controlling the lifting of battery spool.Under the normal condition, the control permanent magnet is in shift state, in case main circuit outage occurs, normal solenoid valve loop can not be opened, just can be by the rotation permanent magnet, and the lifting of the magnetic field control electromagnetic valve core by this permanent magnet generation.The micro motor that the rotation of permanent magnet also can utilize dryelement cell to do power supply drives, and is aided with long-range wired or wireless control again.
The beneficial effects of the utility model: because double loop, the magnetic field control that the solenoid valve of model utility adopts common coil electromagnetism field and permanent magnet to produce to the control of spool, so can realize that the normal unlatching of solenoid valve is used under the main circuit powering-off state.Has extraordinary emergent meaning at some special occasions.When causing main grid power blackout as earthquake etc., opens solenoid valve easily.
Description of drawings
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is the utility model embodiment two a structural representation.
Among the figure, 1. shell, 2. permanent magnet, 3. magnetic isolation board, 4. Returnning spring, 5. coil, 6. valve core of the electromagnetic valve, 7. water valve valve-body, 8. rotating shaft.
Embodiment
Embodiment one: a kind of double control electromagnetic valve, comprise coil 5 and valve core of the electromagnetic valve 6, one magnetic isolation board that can remove 3 is arranged above coil 5 and valve core of the electromagnetic valve 6, and the upper fixed of magnetic isolation board 3 has a powerful permanent magnet 2, and the described magnetic isolation board of removing 3 is manually control.Under the normal condition, magnetic isolation board 3 injects, and cuts off the magnetic field that permanent magnet 2 produces; When the main power circuit outage, when needing opens solenoid valve, just magnetic isolation board 3 can be extracted, the magnetic field that powerful permanent magnet 2 produces is enough to attract valve core of the electromagnetic valve 6 to rise, to reach the purpose of opens solenoid valve.
Embodiment two: a kind of double control electromagnetic valve of another kind of implementation, comprise coil 5 and valve core of the electromagnetic valve 6, and movably powerful permanent magnet 2 is arranged above coil 5 and valve core of the electromagnetic valve 6.That is, by the way realization of the mobile permanent magnet 2 lifting control new to solenoid valve, there is axis hole in one side portion of this permanent magnet, and shaft hole sleeve is connected in the rotating shaft 8, and this rotating shaft 8 departs from valve core of the electromagnetic valve 6 central shafts.By rotating permanent magnet 2, make the magnetic field center of permanent magnet 2 with battery valve spool 6 central shafts are overlapping or skew, to reach the purpose of controlling 6 liftings of battery valve spool.Under the normal condition, control permanent magnet 2 is in shift state, in case main circuit outage occurs, normal solenoid valve loop can not be opened, just can be by rotation permanent magnet 2, and the lifting of the magnetic field control electromagnetic valve spool 6 by these permanent magnet 2 generations.The micro motor that the rotation of permanent magnet 2 also can utilize dryelement cell to do power supply drives, and is aided with long-range wired or wireless control again.
