Description

Technical Field

[0001] The invention relates to the technical field of floats, and in particular to a float structure for high-pressure environments. Background Art

[0002] When using floats in some high-pressure environments, due to the high pressure and the fact that the wall thickness of the float is generally not too large, the float is easily affected by the pressure during use and deformed, thereby affecting the accuracy of liquid level monitoring. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to solve the technical problems in the prior art, the present invention provides a float structure for a high pressure environment.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a float structure for high-pressure environment, placed in a pressure vessel, including a float body, a balance cavity is provided in the float body, a balance hole is opened on the top of the float body, a drainage balance pipe is provided in the float body, one end of the drainage balance pipe is connected to the side wall of the balance hole, and the other end extends to the bottom of the balance cavity.

[0005] The float structure for high-pressure environment of the present invention can make the pressure in the balance cavity and the pressure in the pressure container tend to balance, so that the float body is not affected by the environmental pressure, avoiding the possibility of deformation of the float body due to excessive pressure in the pressure container. At the same time, when liquid is stored at the bottom of the balance cavity, the gas in the float body can be sealed to play a role of liquid sealing. In addition, when the pressure in the float body is greater than the pressure outside the float body, the liquid in the float body can be discharged from the float body through the liquid discharge balance pipe. When there is a slight fluctuation in the environmental pressure, the liquid in the float can be completely discharged to ensure the buoyancy of the float.

[0006] Furthermore, a certain gap is left between the liquid discharge balance pipe and the bottom of the balance chamber to enable the liquid to flow.

[0007] Furthermore, an anti-blocking slope is provided at the bottom of the drainage balance pipe.

[0008] Furthermore, a sawtooth slope is provided at the bottom of the drainage balance pipe.

[0009] Furthermore, the float body adopts a geometric shape.

[0010] Furthermore, the float body and the drainage balance pipe are made of metal or non-metal materials according to use requirements.

[0011] The beneficial effects of the present invention are:

[0012] 1. The liquid discharge balance pipe can balance the pressure in the balance chamber with the pressure in the pressure vessel, so that the float body is not affected by the environmental pressure, avoiding the possibility of deformation of the float body due to excessive pressure in the pressure vessel. At the same time, when there is liquid at the bottom of the balance chamber, it can seal the gas in the float body and play a role of liquid seal. In addition, when the pressure in the float body is greater than the pressure outside the float body, the liquid in the float body can be discharged from the float body through the liquid discharge balance pipe. When there is a slight fluctuation in the environmental pressure, the liquid in the float can be completely discharged to ensure the buoyancy of the float.

[0013] 2. Since the float body is located in the pressure vessel for a long time, and the fluid in the pressure vessel is easy to rotate between liquid and gas under pressure fluctuations, it is easy to cause the fluid to enter the float body through the balance hole and accumulate at the bottom of the balance cavity. After the discharge balance pipe is set, when the pressure in the pressure vessel fluctuates, the pressure in the balance cavity will have a certain hysteresis. For example, when the pressure in the pressure vessel suddenly decreases, the pressure in the balance cavity is higher than the pressure in the pressure vessel. The fluid at the bottom of the balance cavity will be squeezed out of the balance cavity through the discharge balance pipe and flow back into the pressure vessel;

[0014] 3. By setting the anti-blocking slope or the serrated slope, it is possible to avoid the situation where the gap between the drainage balance pipe and the bottom of the balance chamber is small, resulting in poor fluid discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The invention discloses a float structure for a high-pressure environment.

[0024] Reference Figure 1 A float structure for high pressure environment is placed in a pressure vessel, including a float body 1, a balance cavity 11 is arranged in the float body 1, a balance hole 12 is opened on the top of the float body 1, and a liquid discharge balance pipe 13 is arranged in the float body 1, one end of the liquid discharge balance pipe 13 is connected to the side wall of the balance hole 12, and the other end extends to the bottom of the balance cavity 11. The liquid discharge balance pipe 13 can make the pressure in the balance cavity 11 tend to balance with the pressure in the pressure vessel, so that the float body 1 is not affected by the environmental pressure, and the possibility of deformation of the float body 1 due to excessive pressure in the pressure vessel is avoided. At the same time, when there is liquid at the bottom of the balance cavity 11, the gas in the float body 1 can be sealed to play a role of liquid sealing. In addition, when the pressure in the float body 1 is greater than the pressure outside the float body 1, the liquid in the float body 1 can be discharged from the float body 1 through the liquid discharge balance pipe 3. When there is a slight fluctuation in the environmental pressure, the liquid in the float body 1 can be completely discharged to ensure the buoyancy of the float body 1.

[0025] Specifically, the float body 1 adopts a geometric shape, which may be a cylindrical shape, and transition spherical surfaces 14 are provided at both ends of the float body 1. Figures 2 to 4The float body 1 may also be spherical, rectangular, cylindrical or polyhedral, as long as it can float on the liquid surface.

[0026] Furthermore, since the float body 1 is located in the pressure vessel for a long time, and the fluid in the pressure vessel is prone to rotate between the liquid state and the gas state under pressure fluctuations, it is easy to cause the fluid to enter the float body 1 through the balance hole 12 and accumulate at the bottom of the balance cavity 11. After the discharge balance pipe 13 is set, when the pressure in the pressure vessel fluctuates, the pressure in the balance cavity 11 will have a certain hysteresis. For example, when the pressure in the pressure vessel suddenly decreases, the pressure in the balance cavity 11 is higher than the pressure in the pressure vessel. The fluid at the bottom of the balance cavity 11 will be squeezed out of the balance cavity 11 through the discharge balance pipe 13 and flow back into the pressure vessel.

[0027] It should be noted that the bottom of the drainage balance pipe 13 is provided with an anti-blocking inclined surface 131. The anti-blocking inclined surface 131 can avoid the situation where the gap between the drainage balance pipe 13 and the bottom of the balance chamber 11 is too small to cause the fluid to be unable to be discharged. Figure 2 The bottom of the liquid discharge balance pipe 13 may also be a sawtooth slope 132 , as long as the liquid can flow between the liquid discharge balance pipe 13 and the bottom of the balance chamber 11 .

[0028] Furthermore, the float body 1 and the drainage balance pipe 13 are made of metal or non-metal material according to the use requirements, and can be made of stainless steel.

[0029] Working principle: By opening a balance hole 12 on the float body 1, the balance cavity 11 tends to be consistent with the pressure in the pressure container, thus avoiding the possibility of deformation of the float body 1 due to excessive pressure in the pressure container. At the same time, the structure is simple and light, and the cost is low.

[0030] Since the float body 1 is located in the pressure vessel for a long time, and the fluid in the pressure vessel is prone to rotate between liquid and gas under pressure fluctuations, it is easy to cause the fluid to enter the float body 1 through the balance hole 12 and accumulate at the bottom of the balance cavity 11. After the discharge balance pipe 13 is set, when the pressure in the pressure vessel fluctuates, the pressure in the balance cavity 11 will have a certain hysteresis. For example, when the pressure in the pressure vessel suddenly decreases, the pressure in the balance cavity 11 is higher than the pressure in the pressure vessel. The fluid at the bottom of the balance cavity 11 will be squeezed out of the balance cavity 11 through the discharge balance pipe 13 and flow back into the pressure vessel.

[0031] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
