[0001] The invention relates to the technical field of eccentric hemispherical bodies, in particular to an eccentric hemispherical valve provided with a sealing detection device. Background Art

[0002] The eccentric semi-ball valve is a relatively new type of ball valve. It has some advantages unique to its structure, such as no friction when opening and closing, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the actuator. Equipped with a multi-turn electric actuator, it can achieve the adjustment and strict shutoff of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict shutoff; However, when the existing eccentric semi-ball valve leaks at the connection, the staff will not be notified immediately, and when the eccentric semi-ball valve leaks, it will cause a certain amount of resource loss, and some eccentric semi-ball valves are mostly pure electric, and a small number of small ones are purely manual. When the eccentric semi-ball valve is out of power, the closure of the eccentric semi-ball valve cannot be controlled. In addition, when the eccentric semi-ball valve is used for a long time, a certain amount of scale will remain on the inner wall of the valve body. When the oil is transmitted, all the sand and gravel in the oil will be discharged together, and the filtering function cannot be achieved, and the self-cleaning function cannot be achieved.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution of an eccentric hemispherical valve provided with a sealing detection device, comprising a valve body 1 and a controller 8, wherein a shell 11 is provided outside the valve body 1, a sealing detection component 2 is installed at one end of the water inlet of the shell 11, a driving component 3 is installed above the shell 11, an eccentric hemispherical body 12 is installed inside the shell 11, the driving component 3 is connected to the eccentric hemispherical body 12, the eccentric hemispherical body 12 can block the water inlet, and a filter component 4 is installed at the output end of the shell 11, and the filter component 4 can filter the fluid; Therefore, when the device is in use, the water inlet can be monitored in real time through the sealing detection component 2 of the water inlet to prevent leakage of the water inlet of the eccentric hemispherical valve. When the device blocks the water inlet, the driving component 3 can drive the eccentric hemispherical body 12 to rotate, so that the eccentric hemispherical body 12 can block one end of the water inlet of the shell 11, or open the water inlet so that the water in the water inlet can be discharged through the shell 11. At the same time, when the device rotates the eccentric hemispherical body 12, the eccentric hemispherical body 12 can be driven by the driving component 3 to rotate, so that the eccentric hemispherical body 12 can block one end of the water inlet of the shell 11, or open the water inlet so that the water in the water inlet can be discharged through the shell 11. The sealing surface 12 is provided with an inner wall cleaning component 7, and the inner wall of the shell 11 can be cleaned by the inner wall cleaning component 7. At the same time, when the eccentric hemispherical body 12 blocks the water inlet, the inner wall cleaning component 7 can also block the water inlet under the attraction of the magnet. Finally, the liquid discharged through the hemispherical valve will also pass through the filter component 4, and the particles or magnetic particles in the liquid will be collected by the filter component 4, so that the particles in the liquid finally discharged are reduced, making the liquid purer.

[0019] like Figure 1-Figure 3 and Figure 8 As shown, in this embodiment, specifically, a support assembly 5 is installed above the shell 11, and the driving assembly 3 is installed above the support assembly 5. The support assembly 5 includes two groups of support plates 51, one group of the support plates 51 is connected to the top of the shell 11, and the other group of the support plates 51 is installed above it. The two groups of the support plates 51 are fixed and limited by multiple groups of support rods, and multiple groups of power-assisting magnets 52 are respectively arranged on the opposite sides of the two groups of the support plates 51. The power-assisting magnets 52 cooperate with the driving assembly 3, and the power-assisting magnets 52 are equidistantly installed on the two groups of support plates 51; When the device is in use, the driving component 3 can be supported by the support component 5, and the driving component 3 can also be assisted by the support component 5, thereby saving the load of the driving component 3 itself. In specific use, because two groups of support plates 51 are respectively provided with multiple groups of assisting magnets 52, and the arrangement of the assisting magnets 52 is staggered, when the driving shaft of the driving component 3 rotates between the multiple groups of assisting magnets 52, the magnetic force can assist the driving shaft to rotate. When the driving component 3 of the device is rotated in an electric manner, the effect of the assisting magnet 52 will be smaller. When the driving component 3 is manually driven, the staff's effort can be saved, so that the staff can rotate the eccentric hemisphere 12 more labor-savingly, thereby changing the current position of the eccentric hemisphere 12.

[0020] like Figure 1-Figure 3As shown, in this embodiment, specifically, the driving assembly 3 includes a driving compartment 31, a driving motor 32 is installed inside the driving compartment 31, a driving wheel 33 is installed at the output end of the driving motor 32, a driving rod 34 is installed at the bottom of the driving wheel 33, the other end of the driving rod 34 is connected to the eccentric hemisphere 12, a plurality of groups of active magnets 35 are arranged on the driving rod 34, the active magnets 35 cooperate with the auxiliary magnets 52, a hand crank assembly 6 is installed on the side of the driving compartment 31, and the hand crank assembly 6 cooperates with the driving assembly 3; When in use, the driving component 3 of the device can drive the eccentric hemisphere 12 to rotate, and can change the current position of the eccentric hemisphere 12 according to needs. During specific use, the driving motor 32 can drive the active wheel 33 to rotate, and also drive the driving rod 34 at the bottom of the active wheel 33 to rotate. A plurality of groups of active magnets 35 are arranged on the driving rod 34. Because the active magnets 35 cooperate with the auxiliary magnets 52, the driving rod 34 can rotate more easily, thereby reducing the load of the driving motor 32 and reducing the power consumption of the driving motor 32. At the same time, the device can also adjust the eccentric hemisphere 12 through the hand-cranked component 6. When adjusting the eccentric hemisphere 12 through the hand-cranked component 6, because the hand-cranking requires greater force, with the cooperation of the auxiliary magnet 52, the force required for the staff to rotate the hand-cranked component 6 can be reduced.

[0021] like Figure 2-Figure 3 and Figure 8 As shown, in this embodiment, specifically, the assisting magnets 52 are respectively installed on the support plate 51 in a staggered manner, and the N poles of some of the assisting magnets 52 face the active magnet 35, and the S poles of the remaining assisting magnets 52 face the active magnet 35; Because the multiple groups of assisting magnets 52 are installed alternately on the support plate 51, and the magnetic pole directions of the assisting magnets 52 are installed alternately, when the active magnet 35 rotates between the multiple groups of assisting magnets 52, because the magnetic poles of the assisting magnets 52 are constantly changing, the active magnet 35 can rotate more easily among the multiple groups of assisting magnets 52, so when the driving component 3 drives the eccentric hemisphere 12, its own load can be reduced, making the driving component 3 work more labor-saving and convenient.

[0022] like Figure 1-Figure 5As shown, in this embodiment, specifically, the hand crank assembly 6 includes a hand crank bin 61, a partition plate 62 is installed inside the hand crank bin 61, the partition plate 62 is parallel to the bottom of the hand crank bin 61 and installed in the middle thereof, a handle 63 is installed above the hand crank, a transmission rod 64 is installed at the output end of the handle 63, two groups of limit plates 65 are installed on the transmission rod 64, the two groups of limit plates 65 are connected to the transmission rod 64 through bearings, and the two groups of limit plates 65 are installed on the transmission rod 64 on the partition plate 62 On the upper part, a spring is installed between the two groups of the limit plates 65, a driving ring 66 is installed at the bottom of the transmission rod 64, and a plurality of groups of protrusions are arranged on the driving ring 66, a driven wheel 67 is installed at the bottom of the hand-cranked warehouse 61, and the driven wheel 67 is installed at the bottom of the hand-cranked warehouse 61 through a bearing, and the driven wheel 67 is meshed with the driving wheel 33, and a driving groove 671 is opened above the driven wheel 67, and a plurality of groups of protrusions are arranged inside the driving groove 671, and the driving ring 66 and the driving groove 671 cooperate with each other; When the hand-cranked assembly 6 of the device is in use, the eccentric hemispherical body 12 can be driven to rotate by hand-cranking, thereby adjusting the eccentric hemispherical body 12 so that the eccentric hemispherical body 12 can block or open the water inlet. When in use, the staff needs to rotate the handle 63, and when the handle 63 rotates, it will drive the transmission rod 64 to rotate, and then drive the drive ring 66 to rotate together. However, rotating the handle 63 alone cannot adjust the eccentric hemispherical body 12, and the staff needs to press the handle 63 downward so that the drive ring 66 can be pressed down into the drive groove 671. Then the staff member turns the handle 63 again. At this time, because the driving ring 66 cooperates with the driving groove 671, the driven wheel 67 can be driven to rotate together. The driven wheel 67 is meshed with the driving wheel 33, thereby driving the driving wheel 33 to rotate. When the driving wheel 33 rotates, it will drive the transmission rod 64, and at the same time, it will drive the eccentric hemisphere 12 to rotate. The eccentric hemisphere 12 can be adjusted by hand cranking, so that the valve body can be used even when there is no electricity, and the water inlet can also be efficiently blocked.

[0023] like Figure 1-Figure 3 As shown, in this embodiment, specifically, the sealing detection assembly 2 includes a mounting tube 21, the mounting tube 21 is connected to the input end of the housing 11, two groups of grooves and two groups of limit blocks are arranged outside the mounting tube 21, an air pressure sensor is installed inside the groove, and the air pressure sensor is connected to the controller 8; When in use, the sealing detection component 2 of the device can monitor the input end of the shell 11, and can cooperate with the eccentric hemisphere 12 to facilitate the eccentric hemisphere 12 to seal the input end of the shell 11. When in use, the mounting tube 21 can be installed in the input end of the shell 11, and the external input tube needs to be sleeved on the mounting tube 21 and connected to the input end of the shell 11. When a gap appears between the input tube and the input end of the shell 11, the air pressure sensor can detect the change in air pressure, and then the controller 8 will control the eccentric hemisphere 12 to seal the mounting tube 21, and remind the staff to perform maintenance here to prevent the loss of more liquid.

[0024] like Figure 3 As shown, in this embodiment, specifically, a base 13 is installed on the bottom surface of the inner part of the shell 11, and the base 13 is connected to the other end of the eccentric hemispherical body 12. The blocking surface of the eccentric hemispherical body 12 is provided with an inner wall cleaning component 7, and the inner wall cleaning component 7 can clean the inner wall of the shell 11. The inner wall cleaning component 7 includes two groups of rubber hoses 71, and the two groups of rubber hoses 71 are respectively installed at both ends of the blocking surface of the eccentric hemispherical body 12, and magnetic fluid is arranged in the rubber hose 71; When the device is in use, while the eccentric hemisphere 12 is rotated, the inner wall cleaning component 7 of the blocking surface of the eccentric hemisphere 12 will clean the inner wall of the shell 11. At the same time, when the eccentric hemisphere 12 blocks the mounting tube 21, the inner wall cleaning component 7 can block the mounting tube 21 together, thereby achieving a better blocking effect. In specific use, when the eccentric hemisphere 12 is rotated to the mounting tube 21 surface and blocks the mounting tube 21, the magnet on one side of the input end of the shell 11 will attract the magnetic fluid in the rubber hose 71, so that the rubber hose 71 will block both sides of the mounting tube 21, and when the eccentric hemisphere 12 does not block the mounting tube 21, the magnets on other parts of the shell 11 will attract the magnetic fluid in the rubber hose 71, so that the magnetic fluid pushes the rubber hose 71, and then the rubber hose 71 can contact the inner wall of the shell 11, and then when the eccentric hemisphere 12 is rotated, the scale on the inner wall of the shell 11 can be cleaned through the rubber hose 71.

[0025] like Figure 3 and Figure 6 As shown, in this embodiment, specifically, a magnet is disposed outside the housing 11, and the magnet cooperates with the inner wall cleaning component 7; When the eccentric hemispherical body 12 blocks the mounting tube 21, the magnetic fluid in the rubber hose 71 will be attracted by the magnet, and the rubber hose 71 can block the gap between the mounting tube 21 and the eccentric hemispherical body 12. When the eccentric hemispherical body 12 does not block the mounting tube 21, the magnet outside the housing 11 can attract the magnetic fluid in the rubber hose 71, so that the rubber hose 71 contacts the inner wall of the housing 11, and the rubber hose 71 can clean the scale on the inner wall of the housing 11. Therefore, when the cleaning component of the device is in use, it can achieve different effects according to the rotation position of the eccentric hemisphere 12. When the eccentric hemisphere 12 blocks the mounting tube 21, the inner wall cleaning component 7 can block the mounting tube 21 together, thereby achieving a better barrier effect. In specific use, when the eccentric hemisphere 12 rotates to the surface of the mounting tube 21 and blocks the mounting tube 21, the magnet on one side of the input end of the shell 11 will attract the magnetic fluid in the rubber hose 71, so that the rubber hose 71 will block both sides of the mounting tube 21. When the eccentric hemisphere 12 does not block the mounting tube 21, the magnets in other parts of the shell 11 will attract the magnetic fluid in the rubber hose 71, so that the magnetic fluid pushes the rubber hose 71, and then the rubber hose 71 can contact the inner wall of the shell 11, and then when the eccentric hemisphere 12 is rotated, the scale on the inner wall of the shell 11 can be cleaned through the rubber hose 71.

[0026] like Figure 3 and Figure 7 As shown, in this embodiment, specifically, the filter assembly 4 includes a mounting ring 41, the mounting ring 41 can be connected to the output end of the housing 11, a collecting groove 42 is installed between the mounting rings 41, a magnet is installed inside the collecting groove 42, and the collecting groove 42 can collect magnetic particles in the water; When in use, the filter component 4 of the device can filter the discharged liquid so that the magnetic particles in the liquid can be collected. When in use, the mounting ring 41 is installed at the output end of the shell 11. During installation, it is necessary to ensure that one side of the collection tank 42 is installed inside the shell 11. After that, it is necessary to connect the other end of the mounting ring 41 through an external tube. Therefore, when in use, the liquid will first impact the collection tank 42, and the shell 11 with magnetism will be collected by the collection tank 42, thereby achieving filtration of the liquid, so that the liquid can be clearer when discharged.

[0027] like Figure 1-Figure 2 As shown, in this embodiment, specifically, the controller 8 is installed on the housing 11, and a simple control panel 81 is provided on the controller 8; The controller 8 of the device can control various devices on the valve body, and the staff can operate the controller 8 through the control panel 81 on the controller 8 to indirectly control other devices on the valve body.

[0028] Working principle: When the device is in use, the sealing detection component 2 of the water inlet can monitor the water inlet in real time to prevent leakage of the water inlet of the eccentric hemispherical valve. When the device blocks the water inlet, the driving component 3 can drive the eccentric hemispherical body 12 to rotate, so that the eccentric hemispherical body 12 can block one end of the water inlet of the shell 11, or open the water inlet so that the water in the water inlet can be discharged through the shell 11. At the same time, when the device rotates the eccentric hemispherical body 12, due to the eccentric The sealing surface of the hemispherical body 12 is provided with an inner wall cleaning component 7, and the inner wall of the shell 11 can be cleaned by the inner wall cleaning component 7. At the same time, when the eccentric hemispherical body 12 blocks the water inlet, the inner wall cleaning component 7 can also block the water inlet under the attraction of the magnet. Finally, the liquid discharged through the hemispherical valve will also pass through the filter component 4, and the particles or magnetic particles in the liquid will be collected by the filter component 4, so that the particles in the liquid finally discharged are reduced, making the liquid purer.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
