HIGH-VOLTAGE ENVIRONMENTAL DAMAGE
The present invention belongs to the field of liquid level gauges, in particular to a pressure resistant magnetic float for self checking damage in high-pressure environments.
In order to enhance the pressure resistance of magnetic floats, existing technologies mostly use composite floats connected by multiple balls, or install reinforcing ribs inside the magnetic floats, or increase wall thickness. These methods are all based on the structure of the magnetic floats and pressure resistance, which can withstand large pressure differences, insufficient durability, and cannot withstand high pressure. The small damage of the magnetic float is not easy to detect, and it will enter the liquid when used in a high-pressure environment. Although the magnetic float may still float on the liquid surface, due to changes in the overall mass and buoyancy of the magnetic float, the position of the internal magnetic steel shifts, resulting in inaccurate readings.
This phenomenon is difficult to notice through external observation, and it is difficult for workers to determine that the magnetic float has been damaged.
The purpose of the present invention is to solve the problem of small damages of the magnetic float being difficult to detect and affecting its use in high-pressure environments, and to propose a high-voltage environment damage self inspection pressure magnetic float.
In order to achieve the above objectives, the present invention adopts the following technical solution:

The inner shell moves up and down along the vertical tube; A first through-hole is opened on the wall of the vertical pipe, and a piston is installed inside the vertical pipe. The piston moves downwards to block the first through-hole and prevent the upper end of the inner shell from being connected to the outside world; The lower end of the inner shell is provided with a second through-hole, and the lower end of the piston is connected with a rubber plug through a vertical rod. The inner shell moves upwards to maintain concentricity with the shell body, and the rubber plug closes the second through-hole while driving the piston to move upwards, making the upper end of the inner shell connected to the outside world through the first through-hole; The lower end of the shell body is provided with a third through hole, and the upper end of the shell body is equipped with a one-way valve that only enters and exits. The lower end of the one-way valve is equipped with a floating plug, which fills the middle chamber with liquid and moves the floating plug upwards to close the one-way valve; The lower end of the shell body is fixed with a counterweight pipe to ensure that the vertical pipe is in the vertical direction when the entire body enters the water.
As a further description of the above technical solution:
The position of the sliding connection between the outer edge of the vertical pipe and the inner shell is a clearance fit, which ensures that the vertical pipe and the inner shell move relative to each other while maintaining a certain degree of sealing.
As a further description of the above technical solution:
The vertical pipe is fixed with a retaining ring placed above the piston, and there is a first spring between the retaining ring and the piston.
As a further description of the above technical solution:
The piston is provided with a fourth through hole, with the upper end opening of the fourth through hole placed on the upper end face of the piston, and the lower end of the fourth through hole placed on the side wall of the piston and corresponding to the first through hole.
As a further description of the above technical solution:
The one-way valve is composed of a valve body, a stop block, an L-shaped rod, and a second spring. The valve body is cylindrical and vertically inserted on the shell body, and there is a fifth through hole on the valve body.

The upper end of the L-shaped rod is fixed on the stopper, and the lower end is placed in the groove. A second spring is arranged between the lower end of the L-shaped rod and the upper and inner sides of the groove.
As a further description of the above technical solution:
The lower end of the valve body is fixed with a U-shaped rod with an opening facing upwards, and a vertical guide rod is fixed in the middle of the inner bottom surface of the
U-shaped rod. The guide rod is sleeved with a guide sleeve, and the upper end of the guide sleeve is fixed on the lower end face of the floating plug; The floating plug is in the shape of a circular cone.

(2) The magnetic float in the present invention not only ensures no pressure difference between the inside and outside, but also forms a liquid layer in the middle cavity that is not easily deformed, jointly forming this pressure resistant structure, changing the pressure method of the shell to achieve true pressure resistance of the magnetic float, effectively extending its service life. (3) When using the magnetic float of the present invention, if it is in a normal state, the magnetic float can float on the liquid surface when placed in a solution, and gradually drops for a short distance when pressurized before no longer moving; The magnetic float with a damage 504364 inner shell is placed in the solution and falls into the water bottom. When the magnetic float with a damaged outer shell is pressurized again, the liquid level remains unchanged.

During use, the damage of the magnetic float can be detected in a timely manner to avoid affecting its use. (4) The use process of the magnetic float of the present invention is also a self checking process for the magnetic float, and there is no need for specialized testing.

Please refer to Figures 1-10. The present invention provides a technical solution for a withstand voltage magnetic float for self checking damage in a high-pressure environment:
A pressure resistant magnetic float for self inspection of high-pressure environmental damage, comprising a spherical shell 1, a spherical inner shell 2 inside the shell 1, and a circular magnetic steel 3 fixed in a horizontal position inside the inner shell 2; An intermediate cavity 4 is formed between the inner shell 2 and the outer shell 1; A vertical tube 5 is inserted into the upper end of the shell body 1, and the lower end of the vertical tube 5 is placed inside the inner shell 2.
The inner shell 2 moves up and down along the vertical tube 5; A first through-hole 6 is opened on the wall of the vertical tube 5, and a piston 7 is installed inside the vertical tube 5. The piston 7 moves downwards to block the first through-hole 6, preventing the upper end of the inner shell 2 from being connected to the outside world; The lower end of the inner shell 2 is provided with a second through hole 8, and the lower end of the piston 7 is connected to a rubber plug 10 through a vertical rod 9. The inner shell 2 moves upwards to maintain concentricity with the outer shell 1, and the second through hole 8 is closed through the rubber plug 10. At the same time, the piston 7 is driven upwards to connect the upper end of the inner shell 2 with the outer boundary through the first through hole 6; The lower end of shell 1 is provided with a third through-hole 11, the upper end of shell 1 is equipped with a one-way valve 12 that only enters but does not enter, and the lower end of one-way valve 12 is equipped with a floating plug 13.
The liquid fills the middle chamber 4, causing the floating plug 13 to move upwards and close the one-way valve 12; The lower end of the shell body 1 is fixed with a counterweight tube 14, so that when the whole enters the water, the vertical tube 5 is in the vertical direction.
The position where the outer edge of the vertical tube 5 is slidably connected to the inner 204364 shell 2 is a clearance fit, allowing the vertical tube 5 to move relative to the inner shell 2 while maintaining a certain degree of sealing.
The vertical pipe 5 is fixed with a retaining ring 15 located above the piston 7, and there is a first spring 16 between the retaining ring 15 and the piston 7.
The piston 7 is provided with a fourth through hole 17, with the upper end opening of the fourth through hole 17 placed on the upper end face of the piston 7, and the lower end of the fourth through hole 17 placed on the side wall of the piston 7 and corresponding to the first through hole 6.
The one-way valve 12 is composed of a valve body 18, a stop 19, an L-shaped rod 20, and a second spring 21. The valve body 18 1s cylindrical and vertically inserted on the shell body 1, and there is a fifth through hole 22 on the valve body 18. The upper end of the fifth through hole 22 has a small opening and the lower end has a large opening; The stopper 19 1s in a circular platform shape and is inverted above the fifth through-hole 22; There is a groove 23 on the inner edge of the fifth through-hole 22. The upper end of the L-shaped rod 20 is fixed on the stopper 19, and the lower end is placed in the groove 23. A second spring 21 is arranged between the lower end of the L-shaped rod 20 and the upper and inner sides of the groove 23.
The lower end of the valve body 18 1s fixed with a U-shaped rod 24 with an opening facing upwards. À vertical guide rod 25 is fixed in the middle of the inner bottom surface of the
U-shaped rod 24, and a guide sleeve 26 is sleeved on the guide rod 25. The upper end of the guide sleeve 26 is fixed on the lower end face of the floating plug 13; The floating plug 13 is in the shape of a circular cone.
The lower end of the inner shell 2 is fixed with multiple support rods 27, which are distributed in a rectangular array.
Working principle:
When not in the water, piston 7 is placed at the lower end of the vertical pipe 5. At this time, the first through-hole 6 is blocked by the side wall of piston 7, so that the upper end of inner shell 2 is not connected to the outside world; The support rod 27 at the lower end of the inner shell 2 is placed on the inner wall of the shell 1.
Place the magnetic float in the solution inside the main tube of the liquid level gauge alk 204364 float on the liquid surface. When the counterweight tube 14 causes the entire magnetic float to enter the solution, the vertical tube 5 is in a vertical direction.
The solution enters the intermediate chamber 4 through the third through-hole 11, and the air inside the intermediate chamber 4 is discharged through the one-way valve 12; Due to the lack of communication between the upper end of the inner shell 2 and the outside world, the solution cannot enter the inner shell 2 through the second through-hole 8, causing the inner shell 2 to move upwards relative to the outer shell 1 under buoyancy; The inner shell 2 moves upwards along the vertical rod 9 until it is concentric with the shell body 1. At this time, the second through-hole 8 is closed by the rubber plug 10, and the piston 7 is driven upwards by the plug and vertical rod 9, so that the fourth through-hole 17 is connected to the first through-hole 6.
The inner shell 2 is connected to the outside through the first through-hole 6 and the fourth through-hole 17; Due to the closure of the lower end of the inner shell 2, the entire shell floats on the liquid surface under buoyancy, and the middle cavity 4 is level with the liquid surface of the external solution.
Then apply pressure to increase the pressure outside the shell 1. As the inner shell 2 is connected to the outside through the first through hole 6 and the fourth through hole 17, the pressure inside the inner shell 2 and outside the shell 1 also increases, while the pressure in the middle chamber 4 is relatively small. External pressure causes the external solution to enter the middle chamber 4 through the third through hole 11, and the liquid level inside the middle chamber 4 rises to compress the gas inside, Until the liquid level in the middle chamber 4 rises, causing the floating plug 13 to move upwards under buoyancy and closing the one-way valve 12.
When pressurized, due to the solution entering the magnetic float, the position of the magnetic float will gradually decrease, and the pressure inside the outer shell 1 and inner shell 2 will continue to increase. The middle cavity 4 is filled with liquid, and the entire magnetic float will no longer gain weight with the increase of pressure. At this time, it will float on the liquid surface and the magnetic steel 3 position will be at the same level as the external solution liquid level.
At this time, the magnetic float can accurately indicate the liquid level and is not affected 204364 when the pressure increases, and can continue to accurately indicate the liquid level. At the same time, the internal and external pressures of shell 1 and inner shell 2 are equal, and the shell will not be damaged due to force deformation; At the same time, due to the formation of high air pressure inside the inner shell 2 and outside the shell 1, a liquid layer is formed inside the intermediate cavity 4. During the pressurization process, high air pressure is first formed inside the inner shell 2 and outside the shell 1, causing the shell 1 to contract inward and the inner shell 2 to expand outward. As liquid is less easily compressed compared to gas, the inner shell 2 and shell 1 are less likely to deform and cause damage during the pressurization process. Therefore, the magnetic float in the present invention not only ensures no pressure difference between the inside and outside, but also forms a liquid layer in the intermediate cavity 4 that is not easily deformed, jointly forming this pressure resistant structure, changing the pressure mode of the shell to achieve true pressure resistance of the magnetic float, effectively extending its service life, and the magnetic float in the present invention can withstand higher pressure.
It is worth noting that if the inner shell 2 or shell 1 of the magnetic float in the present invention is damaged before use and is not easily visible to the naked eye, and the magnetic float is still placed in the solution, if the inner shell 2 of the magnetic float is damaged, the external solution enters the middle cavity 4 and then enters the inner shell 2, ultimately causing too much solution in the magnetic float to be supported by buoyancy, and the magnetic float sinks into the solution, By displaying a rapid drop in liquid level on the magnetic flap of the liquid level gauge, it can be determined that the magnetic float is damaged and needs to be replaced; If the magnetic float housing 1 is damaged, it will not be affected when entering the solution. However, during pressurization, due to the absence of pressure difference between the inside and outside of housing 1, the solution will not enter the intermediate chamber 4 due to the increase in external pressure. Therefore, the position of the magnetic float remains unchanged. If the liquid level does not change on the magnetic flip plate of the liquid level gauge, it can be determined that the magnetic float has been damaged and needs to be replaced.
In summary, when using a magnetic float, if it is in its normal state, it can float on the liquid surface when placed in a solution, and gradually decrease for a short distance before no longer moving under pressure; The magnetic float with damaged inner shell 2 fell into the water after being placed in the solution, and the liquid level of the magnetic float with damaged outsr 204364 shell 1 remained unchanged when pressurized. When workers observed the magnetic flip plate of the liquid level gauge, it was easy to detect abnormal phenomena, thus determining the damage of the magnetic float.
Therefore, a basin of water can be prepared before use, and the magnetic float can be placed in it to eliminate the damaged magnetic float of inner shell 2. However, the displacement of the damaged magnetic float of outer shell 1 remains unchanged when pressurized, and it still floats on the liquid surface for easy fishing.
The above is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited to this. Technicians familiar with the technical field should be covered by the scope of protection of the present invention by equivalent replacement or modification based on the technical solution and inventive concept of the present invention within the scope of disclosure.
