Description

[0001] Magnetic of airtight type [0002]

The present invention relates to a closed magnet, and more particularly, to a closed magnet designed to protect the magnet susceptible to shock by accommodating a magnet in the case.

Magnets are used in various places using magnetic force, but since they are made by compressing powdered iron in an ordinary state, they have a weak point of impact, and especially since they are weak at corners, There is a problem that can not be done properly.

In such a magnet, in the case of a valve that controls the flow of fluid by a permanent magnet moving between the electromagnet and the iron plate in a solenoid valve such as an electronic valve, the permanent magnet itself touches the iron plate The solenoid valve, such as an electronic valve, can not use the permanent magnet as it is without a separate protective device.

Therefore, if there is a proper protection device for protecting the permanent magnets, the permanent magnets will continue to function properly without fear of breakage even after a long period of use due to numerous movements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a closed magnet according to the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the present invention is not limited to the embodiments disclosed herein but may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein, It is provided to inform.

1 is an exploded perspective view of a closed magnet according to an embodiment of the present invention.

As shown in Fig. 1, a closed magnet according to an embodiment of the present invention comprises a case 3, a magnet 2, and a lid 1.

The case 3 and the lid 1 are formed so as to be opposed to each other to form a female screw thread or a male screw thread in a state in which the magnet 2 is received in the closed case 3, The case 3 and the lid 1 are made of an iron-based metal such as iron or stainless steel. The case 3 is made of a material influenced by magnetism, that is, a material having a magnetic force. It can also be composed of materials that are not affected by magnetism, such as copper, that is, magnetic materials. In addition, the case 3 and the lid 1 may be made of synthetic resin in addition to the above-mentioned metal, and may be formed into a shape suitable for their use.

As shown in FIG. 2, the closed type magnet according to another embodiment of the present invention is the same as the closed type magnet of the embodiment described above except that the case 3, the magnet 2, and the lid 1 are formed. 3 and the lid 1 are joined by casting or spot welding between the case 3 and the lid 1.

3 is a perspective view of a hermetic electronic valve to which a closed magnet according to the present invention is applied.

As shown in Fig. 3, the hermetically sealed electronic valve 5 includes the main body 4, the first electromagnet 5a, the sealed magnet 10 serving as a valve, the second electromagnet 5b, and the on / off switch 6 The closed magnet of the present invention is applied to the closed magnet 10.

The main body 1 has an inlet 7 formed on one side and an outlet 8 formed on the other side so that a fluid passage is formed between the inlet and outlet 8 and the space between the inlet 7 and the outlet 8 Shaped magnet accommodating portion 9 as shown in Fig.

The first electromagnet 5a is installed in close contact with the outer surface of the body 1 opposite to the closed magnet receiving portion 9 between the outlets 8. [

The closed-type magnet 10 serves as a valve for opening and closing the fluid flow while being moved between the fluid passage and the closed-type magnet receiving portion 9 while being accommodated in the closed-type magnet receiving portion 9 in the main body 4 do. It is preferable that the size of the closed magnet 10 is made larger than the diameter of the outlet to close the fluid passage and closed completely.

The second electromagnet 5b is installed in close contact with the outer surface of the enclosed magnet receiving portion 9 on the outer side of the main body 4 and is electrically connected to the first electromagnet 5a.

The on / off switch 6 is connected to the second electromagnet 5b from the outside of the main body 1 and operates only when the polarity of the electromagnet 5b is changed, The electromagnet 5b is not operated.

Since the first electromagnet 5a and the second electromagnet 5b are provided to be affected by the magnetic force together with the enclosed magnet 10, the main body 4 is made of a material which is not affected by the magnetic force, As shown in Fig.

The operation of the hermetically sealed electronic valve with the closed-type magnet of the present invention is as follows.

When the polarity of the first electromagnet 5a is changed to the same polarity as the closed magnet 10 by the operation of the on / off switch 6 and the polarity of the second electromagnet 5b is changed to the other polarity, The sealed magnet 10 in the portion 9 is pushed and attached to the second electromagnet 5b while being pushed to open the outlet 8 of the main body 4 to open the fluid to flow through the fluid passage.
