Description

The rotating body of the jacket is a solenoid valve with a fixed rotation angle

technical field

The invention belongs to a solenoid valve, in particular to a limit rotation solenoid valve whose outer casing rotating body can only rotate at an angle of less than 180 degrees at most.

Background technique

Although the moving body of the current solenoid valve is fixed in motion, it all moves in a straight line, and the disadvantage is that the stroke is very short. If the stroke reaches 6 cm and the load is 50 kg, the weight must be at least 100 kg and the volume must be at least 30* More than 30*40 cubic centimeters, the cost is too high, the static load consumes power, and the practicability is not good.

Contents of the invention

The object of the present invention is to provide a jacket rotary solenoid valve that can limit the rotation angle to a certain angle within 180 degrees, has a fixed starting point and a telescopic trajectory, and is light in weight and small in size.

Structure of the present invention is:

The outer casing rotating body is a solenoid valve with a fixed rotation angle, including a casing 3, an inner fork-shaped fixed body 1 and an outer casing rotating body 2, the inner fork-shaped fixed body 1 is inside the outer casing rotating body 2, and the inner fork-shaped fixed body 1 is fixedly connected with the outer casing 3 , the overcoat rotating body 2 is located in the shell 3, and it is characterized in that: the overcoat rotating body 2 is in the shape of a pipe, and a pair of permanent magnet blocks 4 are arranged on the opposite surface of the arc-shaped inner wall of the overcoat rotating body 2, and the pair of permanent magnet blocks 4 are based on The magnetic pole south pole of one permanent magnet block 4 is opposite to the magnetic pole north pole of the other permanent magnet block 4; the inner fork-shaped fixed body 1 includes a "ten" shaped iron core 5 and a coil 6, and the same straight line iron core in the "ten" shaped iron core 5 The coils 6 wound on the same straight iron core 7 have the same winding direction.

The opposite surface of a pair of permanent magnet blocks 4 is arranged on the opposite surface of the arc-shaped inner wall of the outer casing rotating body 2, which means that the pair of permanent magnet blocks 4 are on the opposite surface of a certain diameter of the outer casing rotating body 2 .

When all coils 6 were not conductive, the two ends of a straight iron core 7 always had to be attracted by two permanent magnet blocks 4 on the opposite surface in the overcoat rotating body 2 in the "ten" shaped iron core 5, so that the straight iron core The two ends of core 7 are very close to two permanent magnet pieces 4. And the two ends of another straight iron core 7 in " ten " font iron core 5 are far away from two permanent magnet blocks 4 .

The principle that the overcoat rotating body 2 corners is a fixed value is: because in the "ten" shaped iron core 5, the coil 6 on the two straight iron cores 7 crossed by "ten" makes the two straight irons The two poles of the core 7 all become the magnetic poles of the electromagnet. If after the coil 6 on the first straight iron core 7 attracted by two permanent magnet blocks 4 conducts electricity in a static state, the two electromagnetic poles of this straight iron core 7 and the magnetic poles of two permanent magnet blocks 4 become north poles To the south pole, because the opposite sex magnetic poles attract each other, then the overcoat rotating body 2 that is fixed together with two permanent magnet pieces 4 just can not rotate. But after the coil 6 on the first straight iron core 7 that is attracted by two permanent magnet blocks 4 conducts electricity at rest, make two electromagnetic poles of this straight iron core 7 and the magnetic pole of two permanent magnet blocks 4 become one end It is the north pole to the north pole, and the other end is the south pole to the south pole. Because the magnetic poles of the same sex repel each other, the two permanent magnet blocks 4 opposite to the north and south poles fixed on the inner surface of the outer rotating body 2 will repel the first straight iron core 7, while Attract the second straight iron core 7 so that the magnetic pole south pole of the second straight iron core 7 is close to the permanent magnet block 4 with the magnetic pole north pole, and simultaneously make the magnetic pole north pole and the magnetic pole south pole of the second straight iron core 7 The permanent magnet block 4 is close. Like this, two permanent magnet blocks 4 opposite to the north and south poles in the overcoat rotor 2 repel the first straight iron core 7 away, and simultaneously attract the second straight iron core 7 that the magnetic poles attract, so that the inner The cross-shaped iron core 5 of the fork-shaped fixed body 1 and the two permanent magnet blocks 4 in the outer rotating body 2 produce relative rotation, so as to achieve the purpose of relative rotation between the inner fork-shaped fixed body 1 and the outer outer rotating body 2 . Because the inner fork-shaped fixed body 1 and the outer casing 3 are fixed, and the outer casing 3 is fixed on other stationary objects, only the outer casing rotating body 2 can rotate.

When all the coils 6 are not conducting, the angle between the first straight iron core 7 and the opposite magnetic poles of the second straight iron core 7 is the constant of the outer rotating body 2. turn angle. Because two straight iron cores 7 angles in a " ten " font iron core 5 are constant, then the angle of rotation of the overcoat rotating body 2 is exactly the numerical value of this angle, can not change. A "ten"-shaped iron core 5 makes the rotation angle of the overcoat rotating body 2 a fixed value, and the "ten"-shaped iron core 5 with different angles makes the rotation angles of the overcoat rotating body 2 different. If the output rotation angle of the overcoat rotating body 2 is to be changed, the angle between the two straight iron cores 7 in the "ten" shaped iron core 5 must be changed.

If a stay rope is connected on the overcoat rotating body 2, the other end of the stay rope can output linear motion, and if a gear is set on the overcoat rotating body 2, linear displacement or circular motion can be output.

For different jacket rotating solenoid valves, the two straight iron cores 7 of the "ten"-shaped iron core 5 can form an included angle of 1 to 179 degrees, and the two straight iron cores 7 of different jacket rotating solenoid valves The rotatable angle of the overcoat rotating body 2 can be 1～179 degrees. That is to say, for different outer casing rotating body solenoid valves, the two straight iron cores 7 can be any value within the range of 1 to 179 degrees, and the rotating angle of the outer casing rotating body 2 can be any value within the range of 1 to 179 degrees. Any value can be used.

Straight iron core 7 is " I " font. Make the two ends of straight iron core 7 wider, prevent coil 6 from slipping out from the end of straight iron core 7.

There are two or more coils 6 on the same straight iron core 7, and the winding directions of the two or more coils 6 are the same. The coil 6 on the straight iron core 7 is to make the straight iron core 7 produce the effect of an electromagnet, in order to make all the coils 6 on a straight iron core 7 have the same conductivity condition, let the straight iron core 7 generate If the maximum magnetic flux is obtained, the winding direction of all coils 6 should be the same.

The outer surface of the casing rotating body 2 is connected with one end of the stay cord 8 , and the other end of the stay cord 8 passes through the hole of the casing 3 . Stay cord 8 is a device for outputting rotational displacement and rotational force of the overcoat rotating body 2 . The hole of shell 3 is used to limit the position of stay cord 8 in shell 3, when making stay cord 8 rotate with outer cover rotating body 2, there is a limited range of motion or trajectory, which is convenient for the movement of stay cord 8 part of shell 3 to be easier to utilize.

The invention has the advantages of being a discontinuous motion solenoid valve with limited rotation angle, fixed starting point and telemotion trajectory, no stall problem, and power output close to a constant value.

After one power-on, the rotating body of the solenoid valve only rotates at an angle of 1 to 179 degrees, that is, the rotation angle of a solenoid valve is a fixed value, and the range is within 1 to 179 degrees, which is limited for some requirements Displacement machinery is the best power source. The limit rotation motor is omitted to add a mechanism for mechanically limiting the rotation of the motor or a mechanism for causing the mechanical transmission to slip and limit rotation.

After one energization, whether it is kept energized or de-energized, the rotating body of the solenoid valve remains motionless, which can keep the driven object in a fixed position forever. If the solenoid valve is powered off, it does not need to consume power if it maintains a certain state for a long time, which is an energy-saving mechanical design. However, the existing motor must rotate in the energized state. If the rotation is restricted, the problem of stalling will occur, which not only consumes power, but also may generate heat and burn out the motor within a few seconds. The solenoid valve of the present invention is a solenoid valve that can output a certain force to keep an object in a certain position without the problem of stalling and consumes no power. the

At the moment when the power is turned on, the output power can be close to the maximum output power value, and the output power value in the entire motion range is close to a constant value, that is to say, it basically forms a smooth straight line. However, the output power value of the existing motor is a curve from small to large. These two output power modes have their own purposes, and the electromagnetic valve of the present invention is suitable for emergency drive machinery.

The magnetic force generated by the coil wound on the fork-shaped fixed body in the initial state of conduction is mainly to make the rotating body rotate from one static position to another static position, that is, the main function of the force generated by the coil is to change the direction of motion of the rotating body. The force generated by the coil is not mainly used to drive the load, so the power of the permanent magnet can be borrowed with a small input of energy, so that the rotating body can obtain a large rotational force. Furthermore, because the solenoid valve can maintain a stable power output state without power consumption and energy consumption, the solenoid valve is energy-saving, environmentally friendly, quick start, fast output of high power, stable power output, precise rotation angle, and output displacement length. Precise solenoid valve.

If the stroke reaches 6 cm and the starting load is 50 kg, the weight is only 2 kg, the volume is only 10*10*15 cubic centimeters, the cost is extremely low, and the static load does not consume power, so it is very practical.
