Abstract

To solve a problem found at a self-holding type electromagnetic valve using a permanent magnet in which a moving length of a plunger was also restricted, in addition, a certain limitation was applied to a pressure of handling fluid, and main problems occurred in this case consist in increasing a moving length of the plunger to expand a valve hole and handling fluid of high pressure.SOLUTION: Two permanent magnets at a fixed side and a movable side on the same axis are oppositely faced to each other in such a way that their polarities may become the same to each other, there is provided a clearance between the two permanent magnets and a ferromagnetic body is moved at the clearance in a direction perpendicular to its axis. When the ferromagnetic body is inserted into the clearance, a magnetic flux of the fixed side magnet is shut off to attract the movable side magnet and in turn when the ferromagnetic body is not inserted into the clearance, the magnetic flux at the fixed side magnet is caused to reach the movable side magnet to repel the movable side magnet and a plunger fixed to the movable side magnet is moved. This invention is also a magnetic force rotating device.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a reciprocating electromagnetic valve that performs self-holding by using a permanent magnet to obtain a holding force at the time of on or off and enables energy saving. It also relates to a magnetic force rotation device.

  The self-holding solenoid valve of Patent Document 1 is configured such that a permanent magnet is disposed between a fixed iron core and a movable iron core so that the operating state of the movable iron core can be held by the attractive force of the permanent magnet.

  The self-holding electromagnetic valve described in Patent Document 1 is normally closed by the force of a spring and is normally open by the magnetic force of a permanent magnet.

Since the self-holding solenoid valve of the prior invention moves the movable iron core by utilizing the imbalance between the repulsive force of the spring and the attractive force of the permanent magnet, the moving force of the plunger is weak and the moving distance is short. Therefore, the pressure of the fluid which can be handled is weak, and it has the fault that the area of the valve hole does not increase.

Patent publication 2002-329023 gazette

  In the method of self-holding the solenoid valve in either state using the difference between the force of the permanent magnet and the spring as used in the prior example, the moving distance of the plunger of the solenoid valve can not be increased. . The first task is to increase the force acting on the plunger, lengthen the moving distance thereof, and increase the cross-sectional area of the valve hole.

In the present invention, when the movable magnet and the fixed magnet face the same axis on the same axis, a repulsive force is exerted. The second problem to be solved is whether to alternately generate an attractive force and a repulsive force without using an electromagnet.

When the adsorption force and repulsion force are alternately repeated on the same axis, the plunger reciprocates. The third problem to be solved is whether to change this reciprocating force into a rotational force.

  In this invention, in order to lengthen the distance which the plunger of a solenoid valve moves, the movable side magnet and the fixed side magnet are arrange | positioned so that the same polarity may oppose on the same axis | shaft. In order to change the repulsive force into an attractive force, an adsorbing plate and a magnetic shield plate are used between the movable magnet and the fixed magnet.

In general, in order to change the repulsive force into an attractive force in the motor, the electromagnet is used to change the direction of the current flowing in the coil using a commutator to change the polarity of the electromagnet, but in the present invention, the electromagnet or the commutator is not used. The magnetic shield plate and the suction plate are used to control the flow of magnetic lines of force generated from the magnet, thereby switching between the attractive force and the repulsive force.

In the present invention, when the attractive force is obtained, the fixed side magnet is covered with a magnetic shield material so that the magnetic lines of force of the fixed side magnet do not reach the movable side magnet. Further, an adsorption plate made of a magnetic material is provided near the movable side magnet. An attracting force is obtained by pulling the movable magnet to the attracting plate. The plunger is moved by this suction force.

When obtaining repulsive force, the magnetic shield material between the movable magnet and the fixed magnet is removed. When the magnetic shielding material is removed, the magnets repel each other because there is nothing to shield the magnetic field between the movable side magnet and the fixed side magnet. The plunger is moved by this repulsive force.

The magnetic shield material is rotated by an electric motor in a direction perpendicular to the axes of the movable magnet and the fixed magnet.

When the attraction force and the repulsion force are alternately repeated on the same axis, the movable magnet reciprocates. A crank mechanism is used to change the reciprocating force into a rotational force.

The crank mechanism is used to convert the rotational motion obtained by the crank mechanism into electrical energy, the output shaft of the crank mechanism is connected to the generator, the output of the generator is connected to the input of the motor, and the magnetic shield material is rotated by the motor. ing.

  In the present invention, since the moving distance of the movable magnet is large, the length that the plunger moves is also large, and the cross section of the valve hole is also large. In addition, since a large force is applied to the plunger, a fluid with a large pressure can be controlled.

Since the moving distance of the movable side magnet is large, it is possible to change the reciprocating motion into a rotational motion. If this rotary motion is used to generate electricity, it is possible to produce energy that is greater than the added energy.

Reference numeral 16 in FIG. 5 denotes a turntable.

The present invention applies the principle of a commercially available magnet stand. The magnetic stand is also attracted or not by whether the magnetic flux leaks or leaks around. Whether or not the magnetic flux is attracted is determined by whether or not the magnetic flux jumps out of the case of the magnet stand made of a ferromagnetic material.

In recent years, with the advent of neodymium magnets, the attractive force of magnets has been remarkably increased. The present invention controls the magnetic force of the neodymium magnet by sealing it with a magnetic shield material.

In the reciprocating solenoid valve of FIG. 1, the movement of the twelve plungers is performed only by the force acting on the two permanent magnets. No mechanical parts such as springs are used.

Two fixed-side magnets and one movable-side magnet are arranged on the same axis so that the same polarity faces each other, and a gap is provided between the two fixed-side magnets and one movable-side magnet, and the magnetic saturation density is between the gaps. The first magnetic shield plate 3 and the suction plate 7 made of a large ferromagnetic material can pass through. Eleven stop plates are provided immediately below one movable side magnet.

In the embodiment of the present invention, 9 rotating shafts and 8 struts are attached at right angles to the rotating shaft, 3 first magnetic shield plates and 7 suction plates are attached to the tips of the struts, and 9 rotating shafts are 10 It is made to rotate with an electric motor. The first magnetic shield plate 3 and the attracting plate 7 are configured to rotate between a gap between the two fixed magnets and the one movable magnet.

Here, a description will be given using the flow of magnetic lines of force when the N poles of the two fixed-side magnets and the one movable-side magnet face each other.

When the first magnetic shield plate 3 and the attraction plate 7 are between the fixed magnet 2 and the movable magnet 1, the magnetic field lines coming out of the second fixed magnet 3 Because it passes through the magnetic shield plate and 7 adsorption plate, it cannot reach even one movable side magnet.

The first magnetic shield plate 3 and the suction plate 7 are made of a magnetic material having a high magnetic saturation density. It has a cross-sectional area that allows all the magnetic lines of force coming from the fixed side of 1 to pass through. Therefore, the lines of magnetic force from the two fixed magnets do not go out of the first magnetic shield plate 3 and the attraction plate 7.

Since the attracting plate 7 is made of a ferromagnetic material, the movable magnet 1 has a downward force as indicated by the arrow in the operation diagram of FIG. 3, and the movable magnet 1 is directed toward the attracting plate 7. Move.

The moving one moving magnet stops in a state of being in contact with the 11 stop plates since there are 11 stop plates directly below.

When the first magnetic shield plate of 3 and the suction plate of 7 are not between the fixed magnet of 2 and the movable magnet of 1, the magnetic flux coming out of the 2 fixed magnets has nothing to be magnetically shielded Therefore, it jumps out toward the second movable side magnet.

Since the movable magnet of 1 and the fixed magnet of 2 have the same opposing polarity, an upward force is exerted on the movable magnet of 1 as shown by the arrows in the operation diagram of FIG. Moves in the opposite direction to the two fixed-side magnets.

2 fixed side magnets are fixed on 5 fixed bases via 4 second magnetic shield plates. The purpose of this second magnetic shield plate is to make it easier for the magnetic flux coming out of the N pole of the second fixed magnet to return to the S pole.

The first magnetic shield plate 3 and the attracting plate 7 are made of a ferromagnetic material, and have a function of blocking the magnetic flux from the fixed magnet 2 and a function of attracting the movable magnet 1. Although two components are used in the embodiment, these two components may be integrated.

The guide rails of 6 reduce the force acting at right angles to the direction of reciprocation applied to the movable magnets of 2 when the first magnetic shield plate of 3 and the suction plate of 7 approach and move away from the movable magnet of 1 It is

When the first magnetic shield plate of 3 and the suction plate of 7 approach and move away from the movable magnet of 1, the 1 movable magnet is moved in the rotational direction by the guide rails of 6.

The force in the reciprocating direction is gradually increased when the first magnetic shield plate of 3 and the suction plate of 7 approach the movable side magnet so that the cross section in the rotational direction of the suction plate of FIG. When the first magnetic shield plate and the attraction plate 7 are moved away from the movable magnet, the force applied in the reciprocating direction is gradually reduced.

By making the movement of the guide rail 6 and the shape of the attracting plate 7 special, when the first magnetic shield plate 3 and the attracting plate 7 rotate, 1 movable side magnet and 2 fixed side The temporal change acting on the movable magnet of 1 of the axial force made by the magnet is such that a sinusoidal wave is drawn.

In the embodiment of the present invention, the first magnetic shield plate 3 and the suction plate 7 are rotated, but may be a linear motion if they are merely moved without being rotated. A solenoid that moves linearly between the first magnetic shield plate 3 and the suction plate 7 can also be used.

The force that the magnet acts on the magnetic body is the same as the direction of movement when approaching, but is opposite to the direction of movement of the magnet when moving away. It is necessary to reduce the influence of the force generated when approaching and moving away. It is effective to provide a plurality of two fixed side magnets and one movable side magnet arranged on the same axis as the first magnetic shield plate 3 and the attracting plate 7 so that the same polarity faces each other.

In the reciprocating electromagnetic valve shown in FIG. 1, the movement of one movable side magnet is transmitted to 12 plungers. In this case, the movement is a linear reciprocating movement. The linear motion is transmitted to the crank mechanism, and the reciprocating motion is changed to the rotational motion, which is a device that converts the reciprocating motion of the movable side magnet of the reciprocating electromagnetic valve of the present invention shown in FIG. .

It is also conceivable to mechanically transmit the force applied to the movable magnet directly to the rotating shaft and rotate the magnetic shield plate 3 and the suction plate 7. In the embodiment of the present invention, it is rotated by 10 electric motors. In the present invention, the linear reciprocating motion of the movable side magnet is changed to rotational motion, and mechanical rotational energy is converted into electrical energy using 15 generators. This electric energy is running 10 motors.

FIG. 4 illustrates the operation of the apparatus in which the reciprocating motion of the movable side magnet of the reciprocating electromagnetic valve according to the present invention is a rotational motion. 3 first magnetic shield plates and 7 suction plates However, whether or not the magnetic field lines from the second fixed side magnet are magnetically shielded or the force acting on the first movable side magnet will be described.

In FIG. 4, how the positional relationship between the first magnetic shield plate 3, the suction plate 7, and the movable magnet 1 affects the movement of the movable magnet 1 is divided into steps 1 to 4. Explains.

Stage 1 is the stage immediately before the first magnetic shield plate of 3 and the suction plate of 7 are inserted in the gap between the stationary magnet of 2 and the movable magnet of 1. Stage 2 is a stage in which the first magnetic shield plate 3 and the suction plate 7 are inserted between the fixed magnet 1 and the movable magnet 1 between the gaps. Stage 3 is a stage immediately after the first magnetic shield plate 3 and the attracting plate 7 are formed between the two fixed magnets and the one movable magnet. Stage 4 is a stage in which the first magnetic shield plate 3 and the attracting plate 7 have completely come out of the gap between the two fixed-side magnets and the one movable-side magnet.

At stage 1, the magnetic flux from the 2 fixed magnets is reduced by the 1st magnetic shield plate of 3 and the suction plate of 7 so that the 1 movable magnet is attracted to the 7 suction plates and the direction of the arrow It moves to. On the other hand, the first magnetic shield plate 3 and the attraction plate 7 are attracted in the rotational direction by the second fixed magnet, and a force in the rotational direction fc in the drawing acts.

In stage 2, the magnetic flux from the fixed side magnet of 2 is completely blocked by the first magnetic shield plate of 3 and the suction plate of 7 so that the movable side magnet of 1 is attracted to the suction plate of 7 most Approach the fixed magnet of 2.

In stage 3, since the magnetic flux coming out from the fixed magnet 2 is going to go out by the first magnetic shield plate 3 and the attracting plate 7, the magnetic flux to be repelled increases. The magnet moves away from the attracting plate 7 and moves upward in the direction of the arrow. On the other hand, the first magnetic shield plate 3 and the attracting plate 7 are attracted to the fixed magnet 2 in the direction opposite to the rotational direction, and a force in the direction of the ball acts on the rotational direction fc in the figure.

In stage 4, the magnetic flux coming out of the second fixed side magnet is maximized because there is no attracting plate of the first first magnetic shield plate 7, and the repulsive force acting on the first movable side magnet is maximized. Therefore, the one movable side magnet moves most upward due to the repulsive force.

In the present embodiment, since the three magnetic shield plates and the seven suction plates are rotated by the ten motors attached to the rotation shaft, the movable side magnet of one repeats the state of stages 1 to 4.

The fc attractive force from the fixed magnet acting on the first magnetic shield plate 3 and the attracting plate 7 is equal in magnitude in steps 1 and 3 and opposite in direction. Although this force is not preferable for smooth rotation of the rotating body, a plurality of first magnetic shield plates and a suction plate of 7 are provided, and when one is a suction force in the rotational direction, the other is By arranging the suction force so that the suction force is opposite to the rotation direction, the forces cancel each other and smooth rotation can be realized.

Two fixed magnets are attached under the first magnetic shield plate 3 and the attracting plate 7. In the state of stage 2, the first magnetic shield plate 3 and the suction plate 7 are attracted from the two stationary magnets with a strong force fp. This force requires unnecessary energy for rotation.

A plurality of 3 first magnetic shield plates and 7 adsorption plates provided with 2 fixed side magnets downward, 3 1st magnetic shield plates and 7 adsorption plates 2 fixed side magnets If the same number of ones with the above are provided, the first magnetic shield plate of 3 and the suction plate of 7 generated in the state of stage 2 can cancel the attraction force fp received from the two stationary magnets. . The first magnetic shield plate 3 and the suction plate 7 are heavy because they are made of iron or nickel, but they can be rotated while floating in the air by adsorbing from the upper direction by magnetic force. . Therefore, the energy required for rotation can be reduced.

In the embodiment of the present invention, the two fixed-side magnets and the one movable-side magnet are arranged on the same axis at a right angle to the rotation axis, and the three first magnetic shield plates and the seven suction plates are rotated. It is also possible to arrange the two stationary magnets and the one movable magnet radially with respect to the rotation axis, and move the three first magnetic shield plates and the seven attracting plates perpendicularly to the rotation axis. FIG. 5 shows an application example of the reciprocating electromagnetic valve of the present invention.

In the application example, the first magnetic shield plate of 3 and the suction plate of 7 are moved perpendicularly to the rotation surface, and the magnetic flux from the fixed side magnet of 2 is cut off. The movable magnet is rotating. An application example is a magnetic rotating device that obtains rotational energy using only magnetic flux.

In the application example, when the first magnetic shield plate 3 and the suction plate 7 are moved upward, there is no magnetic shield in the gap between the fixed magnet 2 and the movable magnet 1 so that the movable magnet 1 is Rotate in the direction of the arrow.

When one movable side magnet approaches the adjacent fixed side magnet, the first magnetic shield plate 3 and the attraction plate 7 are moved downward. The movable side magnet 1 is attracted to the suction plate. The up and down reciprocating motions of the first magnetic shield plate 3 and the suction plate 7 can be converted into the rotational motion of the movable magnet 1.

In the application example of the reciprocating electromagnetic valve of the present invention, the angle perpendicular to the surface of the 7 attracting plate facing the 1 movable side magnet forms a constant angle with the fixed side magnet of 2 and the extension of the rotating shaft. I have to. If the same number of the first magnetic shield plate of 3 and the suction plate of 7 enter the gap and the same number of the magnetic shield plates to go out, the first magnetic shield plate of 3 and the suction plate of 7 are moved. It is possible to reduce the force required for

  The solenoid valve of the present invention achieves the closed state and the open state using the force acting between permanent magnets of the same polarity. Since the magnetic shield plate is moved only when the open state and the closed state are changed, energy supply is not required when the open state and the closed state are maintained. Therefore, energy saving effect can be expected.

Since the closed or open state is maintained only by the force of the magnet without the need for a spring, the force that pushes the plunger moving distance long is also strong. Therefore, high volume, high pressure fluid can be opened and closed.

In the present invention, a large repulsive force and attractive force of a strong magnet are created by rotating the magnetic shield material, and the repulsive force and attractive force are extracted as reciprocating motion. If this reciprocating motion is converted to rotational motion and the generator is operated, it can be expected to take out more energy than the added energy as an output. Therefore, it is expected to be used in various industrial fields.
