Abstract
The utility model discloses a permanent magnet/ electromagnet double-control electromagnetic valve, which comprises a coil and a valve core of the electromagnetic valve. A magnet isolation plate capable of being moved away is arranged above the coil and the valve core of the electromagnetic valve, and a permanent magnet is fixed above the magnet isolation plate. Due to the fact that the electromagnetic valve controls the valve core in a mode that double-loop control of a common coil electromagnetic field and an electromagnetic filed produced by the permanent magnet is utilized, the electromagnetic valve can be opened for use normally when a main circuit is powered off. The electromagnetic valve has special emergency effect in special occasions. For example, when power failure occurs in a main power grid caused by an earthquake, the electromagnetic valve can be manually opened conveniently.
Description
Technical field
The utility model relates to solenoid valve, is specially a kind of permanent magnet/electromagnet 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 adjustment 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 circuits 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.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 stream that also is designed with a parallel connection on the next door of solenoid valve stream uses in order to current failure emergency or maintenance.
Summary of the invention
The purpose of the utility model is the defective that overcomes existing technology, provide a kind of can electronic control a kind of permanent magnet of enable manual control switch/electromagnet double control electromagnetic valve again.
The technological scheme that the utility model is taked is: a kind of permanent magnet/electromagnet 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.
There is sale in described magnetic isolation board market, generally is the goodish coiled material sheet of magnetic conduction, can select as required.The used magnetic isolation board of the present invention can be manual control, also can be the control of dry battery power wireless remote, promptly utilizes dryelement cell to provide the micro motor of power supply to drive, and is aided with telecontrol again and moves magnetic isolation board.
The beneficial effect 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 like earthquake etc., opens solenoid valve easily.
Description of drawings
Fig. 1 is the utility model embodiment one 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. valve body.
Embodiment
Embodiment one: a kind of permanent magnet/electromagnet double control electromagnetic valve; Comprise coil 5 and valve core of the electromagnetic valve 6; One magnetic isolation board 3 that can remove 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 can magnetic isolation board 3 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.
Claims (1)
1. permanent magnet/electromagnet double control electromagnetic valve comprises coil and valve core of the electromagnetic valve, it is characterized in that above coil and valve core of the electromagnetic valve, also having movable magnetic isolation board, upper fixed one permanent magnet of magnetic isolation board.
