[0002] The ball valve was introduced in the 1950s. It has a 90-degree rotating action. The plug body is a sphere, driven by the valve stem, and rotates around the axis of the ball valve.

After the adjusting rod is squeezed, the squeezing ring will no longer squeeze the flexible sealing pad. At this time, the handle is rotated horizontally to open or close the device, so that the action of opening or closing the device and the action of releasing the squeezing of the squeezing ring on the flexible sealing pad are carried out simultaneously, thereby reducing the steps of operation and increasing the convenience of using the device.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 6 As shown, a high-pressure wear-resistant floating ball valve according to an embodiment of the present invention comprises a valve seat 1, a ball 2 is rotatably mounted on the inner wall of the valve seat 1, a flexible sealing pad 3 is symmetrically fixedly mounted on the surface of the ball 2, the outer wall of the flexible sealing pad 3 is in contact with the inner wall of the valve seat 1, an extrusion ring 4 is symmetrically slidably mounted on the inner wall of the ball 2, a plurality of elastic members A5 are fixedly mounted on the outer wall of the extrusion ring 4, one end of the elastic member A5 away from the extrusion ring 4 is fixedly connected to the inner wall of the ball 2, and the side of the extrusion ring 4 away from the elastic member A5 is in conflict with the flexible sealing pad 3; when the device is in a closed state, the two flexible sealing pads 3 are respectively aligned with the positions where the pipeline is connected, and through The flexible sealing gasket 3 can achieve the sealing of the device, and the elastic part A5 is in a compressed state. Under the action of the reverse elastic force of the elastic part A5, the extrusion ring 4 will remain in the state of being squeezed. After being squeezed, the extrusion ring 4 will squeeze the flexible sealing gasket 3. The width of the extrusion ring 4 is smaller than the width of the flexible sealing gasket 3. The flexible sealing gasket 3 is deformed after being squeezed by the extrusion ring 4. The deformed flexible sealing gasket 3 will always keep in contact with the valve seat 1, ensuring the sealing effect after the device is closed, so that the device can still maintain sealing in a high-pressure environment, and at the same time solves the problem that the sealing effect of the traditional device is affected by wear after long-term use.

[0033] like Figures 1 to 7As shown, the inner walls of the two extrusion rings 4 are fixedly installed with vertical rods 6, the outer walls of the vertical rods 6 are slidably connected to the inner wall of the sphere 2, the sides of the two vertical rods 6 close to each other are fixedly installed with cross rods 7, the outer walls of the cross rods 7 are slidably connected to the inner wall of the sphere 2, and the inner wall of the sphere 2 is slidably installed with an adjusting rod 8, one end of the adjusting rod 8 is fixedly installed with a lifting plate 9, the bottom of the lifting plate 9 is fixedly installed with a stop block 11 through a connecting column 10, and the outer wall of the adjusting rod 8 is symmetrically fixedly installed with a receiving plate 12, the receiving plate 12 is fixedly installed with a stop block 11, and the receiving plate 12 is fixedly installed with a stop block 11. The outer wall of the connecting plate 12 is slidably connected to the inner wall of the sphere 2, and elastic parts B13 are fixedly installed between the bottom of the two connecting plates 12 and the inner wall of the sphere 2, and the two cross bars 7 are in conflict with the stop block 11; when the device is in the interception work, the flexible sealing pad 3 is squeezed by the extrusion ring 4 and keeps in contact with the inner wall of the valve seat 1, so as to realize the interception of the device. In this state, the elastic part B13 is in a compressed state, and the reverse elastic force of the elastic part B13 is applied to the adjusting rod 8 through the connecting plate 12. The upward supporting force, the adjusting rod 8 will move the stop block 11 upward through the lifting plate 9 and the connecting column 10. When moving upward, the stop block 11 will squeeze the ends of the two cross bars 7 that are close to each other through the arc surface on its surface. The two cross bars 7 will move to both sides after being squeezed by the stop block 11. When moving, the cross bar 7 will push the extrusion ring 4 to squeeze the flexible sealing pad 3 through the vertical rod 6. At the same time, because the reverse elastic force of the elastic part B13 always exists, the extrusion force of the extrusion ring 4 will also be maintained. A continuous pressure is provided to the flexible sealing pad 3 through the elastic part B13, and a good sealing effect can be maintained even under dynamic or changing working conditions. The flexible sealing pad 3 may be deformed due to factors such as temperature, pressure or material aging during use. The reverse elastic force of the elastic part B13 can partially or completely compensate for this deformation, thereby maintaining effective contact between the flexible sealing pad 3 and the sealing surface. By increasing the contact pressure between the flexible sealing pad 3 and the sealing surface, the reliability and durability of the seal can be significantly improved.

[0034] like Figure 6 to Figure 7As shown, extrusion blocks 14 are symmetrically fixedly installed below the lifting plate 9, and extrusion grooves 15 are provided on the tops of the two cross bars 7. The two extrusion blocks 14 are respectively located above the two extrusion grooves 15; when the device needs to be opened or closed, the ball 2 needs to be rotated. Before rotating the ball 2, the adjusting rod 8 is pressed first. After being pressed, the adjusting rod 8 will move toward the inside of the ball 2. When the adjusting rod 8 moves, it will drive the lifting plate 9 to move. When the lifting plate 9 moves, the stop block 11 will be away from the cross bar 7 through the connecting column 10. The stop block 11 will no longer squeeze the cross bar 7, and at the same time, the extrusion block 14 will be in the lifting plate 9. Move downward in the direction of the extrusion groove 15. When the extrusion block 14 enters the extrusion groove 15, the two cross bars 7 will approach each other through the cooperation of the extrusion block 14 and the inclined surface of the extrusion groove 15. At this time, the extrusion ring 4 no longer squeezes the flexible sealing gasket 3. Then, the device is opened and closed by rotating the ball 2. Since the extrusion ring 4 no longer squeezes the flexible sealing gasket 3 before rotating the ball 2, the flexible sealing gasket 3 will no longer fit tightly with the valve seat 1 due to external pressure, thereby avoiding wear between the flexible sealing gasket 3 and the valve seat 1 when the ball 2 rotates, thereby playing the role of protecting the device.

[0035] like Figures 1 to 5 As shown, a rotating column 16 is fixedly installed on the top of the ball 2, and the outer wall of the rotating column 16 is rotatably connected to the inner wall of the valve seat 1, and a connecting seat 17 is rotatably installed on the inner wall of the rotating column 16. A handle 18 is fixedly installed on the outer wall of the connecting seat 17, and the adjusting rod 8 passes through the inner wall of the rotating column 16 and extends to the outside; when opening or closing the device, the handle 18 is rotated, and the handle 18 drives the connecting seat 17 to rotate. When the connecting seat 17 rotates, it drives the ball 2 to rotate through the rotating column 16, thereby controlling the opening and closing of the device.

[0036] like Figures 1 to 7 As shown, a right-angle plate 19 is fixedly installed on the outer wall of the connecting seat 17, and a lower pressing block 20 is fixedly installed on the end of the right-angle plate 19 away from the connecting seat 17, and the lower pressing block 20 is located above the adjusting rod 8; when opening or closing the device, the handle 18 is lifted first, and the handle 18 will drive the connecting seat 17 to move when being lifted, and the connecting seat 17 will rotate around the position of the connection point between the connecting seat 17 and the rotating column 16 when moving, and the lower pressing block 20 will be driven to rotate through the right-angle plate 19 when the connecting seat 17 rotates, and the adjusting rod 8 will be squeezed when the lower pressing block 20 rotates. After the adjusting rod 8 is squeezed, the squeezing ring 4 will no longer squeeze the flexible sealing pad 3. At this time, the handle 18 is rotated horizontally to open or close the device, so that the action of opening or closing the device and the action of releasing the squeezing of the squeezing ring 4 on the flexible sealing pad 3 are carried out simultaneously, thereby reducing the steps of operation and increasing the convenience of using the device.

[0037] like Figures 2 to 5 and Figure 8As shown, a positioning column 21 is fixedly installed on the inner wall of the stop block 11, and a cylindrical block 22 is symmetrically fixedly installed on the outer wall of the positioning column 21, and a plurality of blades 23 are evenly fixedly installed on the outer wall of the cylindrical block 22; the blade 23 is arranged at the through hole in the center of the sphere 2 through the cylindrical block 22 and the positioning column 21. When the device is turned on, the conveyed medium will pass through the through hole in the center of the sphere 2, that is, the medium will pass through the blade 23. Through the set blade 23, the direction and speed of the medium passing through the sphere 2 can be changed, so that the medium forms an eddy current in the sphere 2. The eddy current helps to distribute the medium more evenly, reduces the direct impact of local high speed on the sphere 2, and helps to alleviate the penetration and impact force of the medium flow, thereby reducing the wear and damage to the sphere 2.

[0038] like Figure 1 to Figure 2 As shown, the inner wall of the valve seat 1 is symmetrically fixed with connecting pipes 24, and the two connecting pipes 24 are fixedly installed with connecting flanges 25 on the sides away from each other; when the device is in use, the two connecting flanges 25 are respectively connected to the pipeline using a connecting piece, so as to realize the installation of the ball valve and form a complete pipeline system. After the ball valve is installed, the fluid can be controlled and regulated by adjusting the ball valve. When it is necessary to transport the medium, the ball 2 is rotated ninety degrees by the handle 18. At this time, the device is in an open state, and the medium can be transported through the device. When it is necessary to intercept the flow, the ball 2 is rotated ninety degrees in the opposite direction by the handle 18 to reset it. At this time, the device is in a closed state, and the medium cannot circulate, thereby achieving the effect of controlling the flow of the medium.

[0039] like Figure 1 An inspection port is provided on one side of the valve seat 1, and an inspection pipe 26 is fixedly installed on the inner wall of the inspection port; by arranging the inspection pipe 26 on the side of the valve seat 1, it is convenient to inspect and maintain the device. The inspection pipe 26 provides a direct and convenient passage for technicians, allowing them to easily approach the interior of the equipment to perform necessary maintenance and inspection work, which avoids excessive disassembly of the equipment due to equipment failure or the need for regular inspection, thereby greatly saving time and cost.

[0040] like Figure 1 As shown, a fixing flange 27 is fixedly installed on the side of the inspection pipe 26 away from the valve seat 1, and a sealing flange 28 is arranged on one side of the fixing flange 27. A connecting bolt 29 is detachably installed between the sealing flange 28 and the fixing flange 27. When the device needs to be inspected and maintained, the connection between the sealing flange 28 and the fixing flange 27 by the connecting bolts 29 is released, and then the sealing flange 28 is removed and the inspection pipe 26 is in an open position, so that the interior of the valve seat 1 can be inspected. When the device is in normal use, the inspection pipe 26 will be sealed by the connecting bolts 29 and the sealing flange 28 to ensure the normal use of the device.

[0041] like Figures 1 to 5As shown, a positioning ring 30 is fixedly installed on the outer wall of the rotating column 16, and the outer wall of the positioning ring 30 is rotatably connected to the inner wall of the valve seat 1, and a support frame 31 is fixedly installed on the outer wall of the valve seat 1. The handle 18 is overlapped on the inner side of the support frame 31, and a flexible grip 32 is fixedly installed on the outer wall of the handle 18; the rotating column 16 is positioned by the arranged positioning ring 30 to ensure the stability of the position of the ball 2. In a natural state, the handle 18 will hang down on the inner side of the support frame 31, and the support frame 31 will support the handle 18. The flexible grip 32 can increase the friction between the handle 18 and the hand, making the grip more stable and not easy to slip. At the same time, the soft material can provide a better hand feel and reduce fatigue during use.

[0042] Working principle: When the device is in use, the two connecting flanges 25 are connected to the pipelines respectively using connectors. When the medium needs to be transported, the ball 2 is rotated ninety degrees by the handle 18. At this time, the device is in an open state and the medium can be transported through the device. When it is necessary to intercept the flow, the ball 2 is reversely rotated ninety degrees by the handle 18 to reset. At this time, the device is in a closed state and the medium cannot circulate, thereby achieving the effect of controlling the flow of the medium. When the device is in a closed state, the two flexible sealing pads 3 are respectively aligned with the positions where the pipelines are connected. The flexible sealing pads 3 can achieve sealing of the device. At the same time, the elastic member A5 is in a compressed state. Under the action of the reverse elastic force of the elastic member A5, the extrusion ring 4 will remain in an extruded state. The extrusion ring 4 is After extrusion, the flexible sealing gasket 3 will be squeezed, so that the flexible sealing gasket 3 and the valve seat 1 are kept in contact, ensuring the sealing effect after the device is closed, and solving the problem of poor sealing effect of the device due to wear. When the device is in use, the elastic part B13 is in a compressed state, and under the action of the reverse elastic force of the elastic part B13, the receiving plate 12 will give an upward supporting force to the adjusting rod 8, and the adjusting rod 8 will move the stop block 11 upward through the lifting plate 9 and the connecting column 10. When moving upward, the stop block 11 will squeeze the two cross bars 7, so that the two cross bars 7 move to both sides. When moving, the cross bar 7 will push the extrusion ring 4 through the vertical rod 6 to squeeze the flexible sealing gasket 3, further keeping the flexible sealing gasket 3 and the valve seat 1 in contact, increasing the sealing effect after the device is closed, and preventing the transported medium from leaking from the valve seat 1.

[0043] When the device needs to be opened or closed, the ball 2 needs to be rotated. Before rotating the ball 2, the adjusting rod 8 is pressed first. After being pressed, the adjusting rod 8 will move toward the inside of the ball 2. When the adjusting rod 8 moves, it will drive the lifting plate 9 to move. When the lifting plate 9 moves, it will make the stop block 11 away from the cross bar 7 through the connecting column 10. The stop block 11 no longer squeezes the cross bar 7. At the same time, the extrusion block 14 will move toward the extrusion groove 15 under the action of the lifting plate 9. When the extrusion block 14 enters the extrusion groove 15, the two cross bars 7 will approach each other through the cooperation of the extrusion block 14 and the inclined surface of the extrusion groove 15. At this time, the extrusion ring 4 no longer squeezes the flexible sealing gasket 3. After that, the ball 2 is rotated to open and close the device. Since the extrusion ring 4 no longer squeezes the flexible sealing gasket 3, the flexible sealing gasket 3 will no longer contact with the valve The seat 1 fits tightly, thereby avoiding wear between the flexible sealing pad 3 and the valve seat 1 when the ball 2 rotates, and plays a role in protecting the device. When opening or closing the device, first lift the handle 18. When the handle 18 is lifted, it will drive the connecting seat 17 to move. When the connecting seat 17 moves, it will rotate around the position of the connection point between the connecting seat 17 and the rotating column 16. When the connecting seat 17 rotates, it will drive the lower pressure block 20 to rotate through the right-angle plate 19. When the lower pressure block 20 rotates, it will squeeze the adjusting rod 8. After the adjusting rod 8 is squeezed, the squeezing ring 4 will no longer squeeze the flexible sealing pad 3. At this time, rotate the handle 18 horizontally to open or close the device, so that the action of opening or closing the device and the action of releasing the squeezing of the squeezing ring 4 on the flexible sealing pad 3 are carried out simultaneously, reducing the steps of operation and increasing the convenience of using the device.

[0044] The blade 23 is arranged at the through hole in the center of the sphere 2 through the cylindrical block 22 and the positioning column 21. When the device is turned on, the conveyed medium will pass through the through hole in the center of the sphere 2, that is, the medium will pass through the blade 23. The arranged blade 23 can change the direction and speed of the medium passing through the sphere 2, so that the medium forms an eddy current in the sphere 2. The eddy current helps to distribute the medium more evenly, reduces the direct impact of local high speed on the sphere 2, and helps to alleviate the penetration and impact force of the medium flow, thereby reducing the wear and damage to the sphere 2.
