Technical Field
[0001] The utility model relates to the technical field of static pressure electrode sealing, and particularly relates to a sealing structural member for a static pressure electrode. Background Technique
[0002] Static pressure electrode sealing is a technology used to maintain the seal between an electrode and a fluid, ensuring the isolation of the electrode and the fluid under high-pressure environments and preventing fluid leakage. This sealing mechanism is usually applied to occasions where precise measurement of fluid pressure or fluid experiments are required. The sealing liquid for sealing is sealed inside through a sealing structural member.
[0003] The existing sealing structural members for static pressure electrodes have insufficient sealing at the electrode connection, and the liquid is prone to leak through the electrode connection. Moreover, when injecting liquid into the existing sealing structural members, air is easily left inside, which easily leads to uneven pressure and affects the sealing effect, bringing certain adverse effects to the use process of people. To solve the deficiencies of the existing technology, we propose a sealing structural member for a static pressure electrode. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide a sealing structural member for a static pressure electrode, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A sealing structural member for a static pressure electrode, including a main body of the sealing structural member. A fixing column penetrates through the top of the main body of the sealing structural member. A groove is opened at the top of the fixing column. A sealing ring is detachably installed at the bottom of the inner wall of the groove opened by the fixing column. An electrode column penetrates through the center of the bottom of the inner wall of the groove opened by the fixing column. A sealing sleeve is slidably connected inside the groove opened by the fixing column. A sealing pad is detachably installed at the bottom of the sealing sleeve. A sealing shell is detachably installed at the top of the main body of the sealing structural member. Support columns are symmetrically and detachably installed at the top inner wall of the sealing shell. A liquid injection pipe is detachably installed at the top of the sealing shell. A sealing bolt is threadedly connected to the top of the liquid injection pipe. One end of the sealing bolt movably penetrates through a push rod. One end of the push rod abuts against a floating ball. A support rod is detachably installed at the center of the bottom of the floating ball. A floating plate is detachably installed at one side of the bottom of the floating ball.
[0007] Preferably, a first through hole and a second through hole are symmetrically opened at the top of the sealing shell. The outer side of one end of the floating plate is slidably connected inside the second through hole opened by the sealing shell.
[0008] Preferably, a storage groove is opened at the center of the top of the sealing shell. The outer side of one end of the support rod is slidably connected inside the storage groove opened by the sealing shell.
[0009] Preferably, the bottom of the floating ball abuts against the top of the sealing shell, and there is a gap between the top of the floating ball and the inner wall of the liquid injection pipe.
[0010] Preferably, the bottom of the support column abuts against one side of the top of the sealing sleeve, and the inner part of the sealing sleeve is movably sleeved on the outer side of one end of the electrode column.
[0011] Preferably, the top of the sealing ring abuts against the bottom of the sealing gasket, and the bottom of the sealing gasket abuts against the bottom of the inner wall of the groove formed in the fixed column.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. In the utility model, the sealing shell drives the support column to push and squeeze the sealing sleeve, and the sealing sleeve drives the sealing gasket to be tightly pressed against the bottom of the inner wall of the groove of the fixed column and the top of the sealing ring. Under the up and down extrusion of the sealing sleeve and the sealing ring, the sealing gasket is closely attached to the groove formed in the fixed column. By using the deformation of the sealing gasket generated under the extrusion of the sealing sleeve and the sealing ring, the sealing gasket fills the gap between the groove formed in the fixed column and the sealing sleeve. The sealing gasket serves as the seal at the connection gap between the electrode column and the fixed column. When the sealing shell is filled with the sealing liquid, the liquid presses the sealing sleeve and the sealing gasket more tightly against the connection gap between the electrode column and the fixed column, preventing the leakage of the liquid from the connection gap between the electrode column and the fixed column and improving the overall sealing performance.
[0014] 2. In the utility model, the sealing liquid is continuously injected through the first through hole formed in the sealing shell. The residual air in the sealing shell is discharged into the liquid injection pipe by driving the floating ball through the floating plate. The sealing shell is filled with the liquid, and the liquid pressure in the sealing shell is more uniform. Therefore, the pressure of the liquid on the sealing sleeve is more uniform, and there will be no sealing leakage caused by the residual gas passing through the gap between the sealing gasket and the groove formed in the fixed column, improving the overall sealing safety.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Embodiment 1, as Figures 1-3 shown, a sealing structure for a static pressure electrode includes a main body 1 of the sealing structure. A fixed column 2 is connected through the top of the main body 1 of the sealing structure. A groove is opened at the top of the fixed column 2. A sealing ring 3 is detachably installed at the bottom of the inner wall of the groove opened in the fixed column 2. By the support column 8 in the sealing shell 7 pushing and squeezing the sealing sleeve 5, the sealing sleeve 5 drives the sealing gasket 6 to tightly press against the bottom of the inner wall of the groove of the fixed column 2 and the top of the sealing ring 3. Under the up-and-down extrusion of the sealing sleeve 5 and the sealing ring 3, the sealing gasket 6 closely fits in the groove opened in the fixed column 2. Utilizing the deformation of the sealing gasket 6 generated under the extrusion of the sealing sleeve 5 and the sealing ring 3, the sealing gasket 6 fills the space between the groove opened in the fixed column 2 and the sealing sleeve 5. The sealing gasket 6 serves as the seal at the connection gap between the electrode column 4 and the fixed column 2. When the sealing liquid fills the sealing shell 7, the liquid presses the sealing sleeve 5 and the sealing gasket 6 more tightly at the connection gap between the electrode column 4 and the fixed column 2, preventing liquid leakage from the connection gap between the electrode column 4 and the fixed column 2 and improving the overall sealing performance.
[0022] Embodiment 2, as Figures 2-4 shown, a sealing structure for a static pressure electrode. During the process of filling the sealing liquid in the sealing shell 7, the residual air in the sealing shell 7 is pushed by the sealing liquid to push the floating plate 14 in the second through hole opened in the sealing shell 7. The floating plate 14 pushes the floating ball 12 to drive the support rod 13 to float in the liquid injection pipe 9. As the sealing liquid is continuously injected through the first through hole opened in the sealing shell 7, the residual air in the sealing shell 7 is discharged into the liquid injection pipe 9 by pushing the floating plate 14 to drive the floating ball 12. The sealing shell 7 is filled with liquid, and the liquid pressure in the sealing shell 7 is more uniform. Thus, the pressure of the liquid on the sealing sleeve 5 is more uniform, and there will be no sealing leakage caused by the residual gas passing through the gap between the sealing gasket 6 and the groove opened in the fixed column 2, improving the overall sealing safety.
[0023] It should be noted that the present utility model is a sealing structural member for a static pressure electrode. When in use, first, the sealing sleeve 5 is sleeved outside the electrode post 4. The sealing sleeve 5 drives the sealing gasket 6 into the groove opened in the fixed post 2. The bottom of the sealing gasket 6 abuts against the bottom of the groove of the fixed post 2 and the top of the sealing ring 3. Then, the sealing shell 7 is installed on the main body 1 of the sealing structural member. The support column 8 in the sealing shell 7 pushes and squeezes the sealing sleeve 5. Under the up-and-down extrusion of the sealing sleeve 5 and the sealing ring 3, the sealing gasket 6 closely fits in the groove opened in the fixed post 2. When the sealing liquid fills the sealing shell 7, the pressure of the liquid presses the sealing sleeve 5 tightly outside the electrode post 4. At the same time, the liquid presses the sealing sleeve 5 to drive the sealing gasket 6 to press against the bottom of the inner wall of the groove of the fixed post 2 and the top of the sealing ring 3. The sealing gasket 6 serves as the seal at the connection gap between the electrode post 4 and the fixed post 2, achieving the purpose of enhancing the overall sealing performance.
[0024] After the sealing shell 7 is installed on the main body 1 of the sealing structural member, the sealing liquid is injected into the liquid injection pipe 9 through the hole where the top of the liquid injection pipe 9 is threadedly connected to the sealing bolt 10. After the sealing liquid enters the liquid injection pipe 9, it slowly enters the sealing shell 7 through the first through hole opened in the sealing shell 7 under the drainage of the floating ball 12 until the sealing shell 7 is filled with the sealing liquid. During this process, the sealing liquid discharges the air in the sealing shell 7. When the sealing liquid is about to fill the sealing shell 7, the sealing liquid pushes the residual air to push the floating plate 14 in the second through hole opened in the sealing shell 7. The floating plate 14 pushes the floating ball 12 to drive the support rod 13 to float in the liquid injection pipe 9. At the same time, as the sealing liquid is continuously injected through the first through hole opened in the sealing shell 7, the residual air in the sealing shell 7 is discharged into the liquid injection pipe 9 by pushing the floating plate 14 to drive the floating ball 12. The sealing shell 7 is filled with the liquid. Then, the mixed liquid and air in the liquid injection pipe 9 are enclosed in the liquid injection pipe 9 as the floating ball 12 floats, and then the injection is stopped. The push rod 11 driven by the sealing bolt 10 is installed on the liquid injection pipe 9. The push rod 11 movably penetrating through the sealing bolt 10 drives the floating ball 12 to drive the support rod 13 to fall in the liquid injection pipe 9 under the drive of the sealing bolt 10. The floating ball 12 no longer blocks the hole at the top of the liquid injection pipe 9. The residual gas in the liquid injection pipe 9 is discharged under the extrusion of the floating ball 12 and the push rod 11. Then, the sealing bolt 10 is threadedly sealed above the liquid injection pipe 9, achieving the purpose of exhausting the gas in the sealing shell 7 to complete the sealing.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
