Detailed Description
The structure and operation of the present invention will be further described in detail with reference to the accompanying drawings.
In one embodiment of the present invention, as shown in fig. 1, the magnetic safety valve is composed of a sealing seat 1, a sealing gasket 2, a buffer magnet 3, a valve core 4, a first sealing magnet 5, a second sealing magnet 6, an adjusting plate 7, an adjusting screw 8, a safety valve cover 10, a safety valve body 11, and the like.
Wherein, the seal receptacle 1 is installed below the safety valve body 11, and the valve core 4, the first seal magnet 5, the second seal magnet 6 and the adjusting plate 7 are installed in the safety valve body 11. When the first sealing magnet 5 and the second sealing magnet 6 are assembled, the adjacent two sides have the same magnetic poles, and a repulsive force is formed. The valve core 4 is attached to the sealing surface of the sealing seat 1, and the first sealing magnet is arranged on the valve core 4. The adjusting plate 7 is installed above the second sealing magnet 6, and the safety valve cover 10 is installed at the uppermost end of the safety valve body 11. The adjusting screw 8 is assembled on the safety valve cover 10 in a threaded mode and extends into the safety valve body 11 to be connected with the adjusting plate 7. A lock nut 9 is mounted on the adjusting screw 8. The adjusting screw 8 is used for adjusting the distance between the two magnets so as to achieve the purpose of adjusting the sealing pressure.
Referring to fig. 2, two buffer magnets 3 are oppositely arranged on the sealing surface of the sealing seat 1 and the sealing surface of the valve core 4, and the magnetic poles of the two adjacent surfaces of the buffer magnets on the two sealing surfaces are the same.
By adopting the structure, the magnetic safety valve utilizes the principle that like poles of magnets repel each other, and the repulsive force of the magnets is used as the loading force of the safety valve to balance the force on the valve core, so that the safety valve is closed and opened.
The working mode of the magnetic safety valve is as follows: the installation seat of the safety valve is connected with a container (or a pipeline), when the pressure in the container is larger than the repulsive force of the sealing magnet in the safety valve, the first sealing magnet 5 moves upwards, the valve core 4 is lifted, a gap is generated between the sealing surface of the valve core 4 and the sealing surface of the sealing seat 1, the safety valve is opened at the moment, and pressure medium flows out of the gap and is discharged through the discharge port of the safety valve body 11. When the pressure in the container is smaller than the repulsive force of the sealing magnet in the safety valve, the first sealing magnet 5 moves downwards, the valve core 4 moves downwards, the sealing surface of the valve core and the sealing surface of the sealing seat 1 are attached, and therefore media are prevented from flowing out through the sealing surface, the safety valve is closed at the moment, and when the safety valve is closed, due to the fact that the buffering magnets are installed on the sealing surface, impact of the valve core on the sealing seat can be avoided through two repulsive forces between the buffering magnets.
