Description

[0001] The invention relates to the technical field of ball valves, in particular to a low-load high-pressure resistant valve suitable for the coal, petrochemical and wind power industries. Background Art

[0002] A ball valve is a valve whose opening and closing part is a ball. The ball rod is driven by the valve stem and rotates around the axis of the valve stem. The ball is provided with a channel for the flow of the medium. The medium flows in the channel of the ball to achieve conduction. When the ball rotates until the channel is closed, it blocks the medium and achieves a blocking effect.

[0003] However, the ball valve can only seal the medium passing through the valve body, while the leakage generated at the connection points at both ends of the ball valve cannot be sealed by the ball valve. Although the leakage can be detected by general detection components and the users and staff can be reminded to perform maintenance, the leakage may continue to expand. Even if it does not expand, long-term leakage will cause more losses. In addition, when leakage occurs in the coal, petrochemical and wind power industries, if it is not quickly sealed, huge losses will occur. Summary of the invention

A mating screw is installed at the other end of the mating disk, and the other end of the mating screw is connected to the main sphere. A screw groove is opened on the main sphere, and the mating screw is connected to the screw groove.

[0008] Furthermore, the driving disk is composed of multiple groups of magnets, and the matching disk is also composed of multiple groups of magnets. The magnets on the driving disk are respectively installed on the driving disk in an alternating manner, and the magnets on the matching disk are also respectively installed on the matching disk itself in an alternating manner.

[0009] The magnets on the driving disk have N poles of half of the magnets facing the matching disk, and S poles of the other half of the magnets facing the matching disk;

[0010] The magnets on the matching disk have N poles of half of the magnets facing the driving disk, and S poles of the other half of the magnets facing the driving disk.

[0011] Furthermore, when the mating screw rotates forward: the main ball rotates along with the mating screw;

[0012] When the matching screw is reversed, the matching screw will be separated from the main ball.

[0013] Furthermore, the adjustment component includes an inclined block, and adjustment motors are respectively installed on both sides of the inclined block.

[0023] 2. When the valve body is opened and closed, the input end can be closed by the main ball. However, during the closing process of the ball valve, some gas or liquid will enter the flow channel of the main ball through the gap of the flow channel of the main ball. When the main ball completely closes the valve body, the liquid or gas will remain in the flow channel of the main ball when it is closed, thereby increasing the load of the main ball. When the device is closed, it can first block the flow channel of the main ball through the auxiliary ball, quickly block it, and rotate the main ball at the same time. Even if some gas still enters the flow channel of the main ball through the gap, the remaining liquid or flow can be discharged at this time.

[0024] 3. When leakage occurs at the connection points at both ends of the valve body, or the flow rate changes dramatically, the magnetic coupling component of the valve body can drive the matching screw to separate the matching screw from the main ball and the valve body. At the same time, the adjusting component will drive the adjusting screw to separate the adjusting screw from the auxiliary ball, the main ball and the valve body. After that, the adjusting component will drive the pushing and blocking component to push the loosened main ball so that the main ball can resist the external feed pipe, thereby sealing the pipeline.

DETAILED DESCRIPTION

[0034] 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.

[0035] Example: Figure 1-Figure 8 As shown, the present invention provides a low-load high-pressure resistant valve technical solution suitable for the coal, petrochemical and wind power industries, including a valve body 1 and a controller 6, characterized in that: a magnetic coupling component 2 and an adjusting component 3 are installed on the side of the valve body 1, a sealing component 4 is installed at the input end of the valve body 1, and a push-blocking component 5 is installed at the output end of the valve body 1, a main ball 11 is installed inside the cavity of the valve body 1, the main ball 11 cooperates with the magnetic coupling component 2, an auxiliary ball 12 is installed inside the main ball 11, the auxiliary ball 12 cooperates with the adjusting component 3, and the adjusting component 3 also cooperates with the push-blocking component 5, the main ball 11 and the auxiliary ball 12 can both control the flow, and the push-blocking component 5 can assist in blocking the valve body 1;

[0036] Therefore, when the device is in use, it can be applied to the coal petrochemical industry and wind power industry through the valve body 1. When the valve body 1 transmits liquid or gas, it can block the transmission of the input end by itself when leakage occurs, so as to generate more losses before maintenance. When it is used specifically, the input end of the valve body 1 is reinforced by the sealing component 4, and the plugging component 5 of the device can seal the leakage caused by aging at the connection of the valve body 1, so as to reduce the leakage consumption caused by aging when the staff arrives for maintenance. In normal operation, the valve body 1 can adjust the main ball 11 through the magnetic coupling component 2, and can adjust the auxiliary ball 12 through the adjustment component 3, and at the same time adjust the component 3 can also drive the plugging assembly 5. The main sphere 11 and the auxiliary sphere 12 are respectively provided with flow channels, and the auxiliary sphere 12 is installed in the flow channel of the main sphere 11. At the same time, the main sphere 11 and the auxiliary sphere 12 are concentrically arranged together. Therefore, when the device is blocking liquid or gas, even if the main sphere 11 is completely closed, the flow channel of the main sphere 11 can be blocked by quickly rotating the auxiliary sphere 12. Then, when the main sphere 11 is rotated, the liquid or gas remaining in the flow channel can be discharged. Therefore, when the device is in use, it can speed up the closing process and reduce the liquid or gas flowing into the flow channel during the closing process, and can block the input pipe after leakage occurs at the connection.

[0037] like Figure 1 and Figure 7 As shown, in this embodiment, specifically, the sealing component 4 includes a fixing plate 41 and a mounting plate 42, the fixing plate 41 and the mounting plate 42 are respectively mounted on the valve body 1 and the external pipe, the fixing plate 41 and the mounting plate 42 are connected by a flange, a flow sensor is installed between the fixing plate 41 and the mounting plate 42, and the flow sensor is connected to the controller 6;

[0038] When in use, the sealing component 4 of the device can reinforce the connection at the input end of the valve body 1. Because half of the connection between the valve body 1 and the pipeline is exposed to the outside, long-term exposure to external wind and rain will cause aging of the pipeline and the connection. Then, through the fixing plate 41 and the mounting plate 42 of the sealing component 4, the input end of the valve body 1 can be reinforced and the loss of the connection caused by the outside world can be reduced. At the same time, the sealing component 4 of the device can also detect the flow at the input end of the valve body 1. By detecting the flow and the change in the flow, the closing state of the valve body 1 can be known. At the same time, when a leakage occurs, the flow rate will still change, and the leakage can also be detected.

[0039] like Figure 1-Figure 4 and Figure 6As shown, in this embodiment, specifically, the magnetic coupling component 2 includes a support plate 21, the support plate 21 is installed on the valve body 1, a main valve motor 22 is installed on the support plate 21, the support plate 21 is connected to the main valve motor 22 through multiple groups of cylinders, a driving disk 23 is installed at the output end of the main valve motor 22, a matching disk 24 is installed between the support plates 21, a matching screw 25 is installed at the other end of the matching disk 24, the other end of the matching screw 25 is connected to the main ball 11, a screw groove is opened on the main ball 11, and the matching screw 25 is connected to the screw groove;

[0040] When the magnetic coupling component 2 of the device is in use, it can drive the matching disk 24 in a state of zero contact with the matching disk 24. Because the matching disk 24 is connected to the main ball 11 through the matching screw 25, when the matching disk 24 rotates, it will drive the main ball 11 to rotate. The main valve motor 22 of the device is connected to the support plate 21 through the cylinder. When the device is in use, the main valve motor 22 can be driven to rise and fall through the cylinder, so that the main valve motor 22 is close to or away from the support plate 21, so that the driving of the main valve motor 22 can be The disk 23 is close to or away from the mating disk 24. When the driving disk 23 is away from the mating disk 24, the magnetic connection between the driving disk 23 and the mating disk 24 is weak. When the mating screw 25 is separated from the main ball 11, the driving disk 23 will attract the mating disk 24 to separate the mating screw 25 from the outside of the valve body 1. When the driving disk 23 is close to the mating disk 24, the magnetic connection between the driving disk 23 and the mating disk 24 will be stronger, which can drive the mating disk 24 to rotate, thereby driving the main ball 11 to rotate, and then changing the closing and opening of the valve body 1.

[0041] like Figure 4 As shown, in this embodiment, specifically, the driving disk 23 is composed of multiple groups of magnets, and the matching disk 24 is also composed of multiple groups of magnets. The magnets on the driving disk 23 are respectively staggeredly installed on the driving disk 23, and the magnets on the matching disk 24 are also respectively staggeredly installed on the matching disk 24 itself;

[0042] The magnets on the driving disk 23 have N poles of half of the magnets facing the matching disk 24, and S poles of the other half of the magnets facing the matching disk 24;

[0043] The magnets on the matching disk 24 have N poles of half of the magnets facing the driving disk 23, and S poles of the other half of the magnets facing the driving disk 23;

[0044] The driving disk 23 and the matching disk 24 of the device are both composed of multiple groups of magnets. The magnets on the driving disk 23 are arranged in an interlaced manner, and the magnetic pole directions of the magnets arranged in an interlaced manner are also arranged in an interlaced manner; at the same time, the magnets on the matching disk 24 of the device are also arranged in an interlaced manner. The arrangement of the magnets and the arrangement of the magnetic poles are similar to those of the driving disk 23. Therefore, when the driving disk 23 and the matching disk 24 are relative to each other, because the magnetic pole directions and the arrangement directions of the magnets are interlaced, the magnetic connection between the driving disk 23 and the matching disk 24 will be stronger, so that when the driving disk 23 drives the matching disk 24, because the magnetic connection between the two is stronger, when the driving disk 23 is combined with the driving disk 23 and approaches the matching disk 24, the matching disk 24 can match the rotation of the driving disk 23 and rotate, thereby driving the main sphere 11 to rotate.

[0045] like Figure 6 As shown, in this embodiment, specifically, when the mating screw 25 rotates forward: the main ball 11 rotates along with the mating screw 25;

[0046] When the mating screw 25 is reversed, the mating screw 25 will be separated from the main ball 11;

[0047] When the mating screw 25 of the device rotates forward, the end of the mating screw 25 is against the bottom of the screw groove. When the mating screw 25 rotates again, the forward direction is blocked, and when the mating screw 25 rotates, it can drive the main ball 11 to rotate; when the mating screw 25 is reversed, the mating screw 25 will slowly separate from the main ball 11, and the mating screw 25 will gradually rise, so that the mating disk 24 and the driving disk 23 gradually approach each other. The device will only reverse the mating screw 25 when leakage occurs at the connection of the valve body 1, so that the mating screw 25 can be separated from the valve body 1, and then cooperate with the push plug component 5 to seal the pipeline at the input end.

[0048] like Figure 2 and Figure 8 As shown, in this embodiment, specifically, the adjustment component 3 includes an inclined block 31, and the two surfaces of the inclined block 31 are respectively installed with adjustment motors 32, one group of the adjustment motors 32 cooperates with the auxiliary ball 12, and the other group of the adjustment motors 32 cooperates with the push-blocking component 5;

[0049] When in use, the adjusting component 3 of the device can act on the auxiliary ball 12 and the pushing component 5 respectively, and the inclined block 31 included in the adjusting component 3 can support the two groups of adjusting motors 32 to limit the positions of the adjusting motors 32.

[0050] like Figure 6As shown, in this embodiment, specifically, an adjusting screw 33 is installed on the bottom surface of the valve body 1, and the other end of the adjusting screw 33 is connected to the auxiliary ball 12 through the main ball 11. The auxiliary ball 12 is also provided with a screw groove, and the adjusting screw 33 is connected to the screw groove on the auxiliary ball 12. The other end of the adjusting screw 33 is connected to a set of adjusting motors 32;

[0051] When the adjusting screw 33 rotates forward, the auxiliary ball 12 rotates along with the adjusting screw 33.

[0052] When the adjusting screw 33 is reversed, the adjusting screw 33 will be separated from the auxiliary ball 12;

[0053] When a group of adjusting motors 32 in the adjusting component 3 drives the adjusting screw 33, the adjusting screw 33 can drive the auxiliary sphere 12 to rotate because the output end thereof is against the bottom of the screw groove, so that the auxiliary sphere 12 can change the direction of the flow channel, and the auxiliary sphere 12 can block the flow channel in the main sphere 11. When the adjusting screw 33 is reversed, it will move along the screw groove toward the outside of the main sphere 11 and the valve body 1 until the main sphere 11 is separated from the valve body 1, and then the separated main sphere 11 is connected to the pipe connected to the input end of the valve body 1.

[0054] like Figure 2 and Figure 5 As shown, in this embodiment, specifically, the push-blocking assembly 5 includes multiple groups of limiting sleeves 51 and drive rings 52, the drive ring 52 is installed outside the output end of the valve body 1 through a bearing, a group of the output end of the regulating motor 32 is connected to the drive ring 52, the drive ring 52 is composed of multiple groups of magnets, the limiting sleeves 51 are equidistantly installed at the output end of the valve body 1, and the multiple groups of the limiting sleeves 51 are respectively installed with push rods 53 inside, the push rods 53 are connected to the limiting sleeves 51 through threads, and the push rods 53 are composed of multiple groups of magnets;

[0055] When in use, another set of adjustment motors 32 on the adjustment component 3 can drive the drive ring 52 to rotate. Because the drive ring 52 and the push rod 53 cooperate with each other, when the drive ring 52 rotates, it will drive the push rod 53 to rotate together. However, because the push rod 53 is limited by the limiting sleeve 51, the push rod 53 will move in the output direction of the limiting sleeve 51 under the limitation of the limiting sleeve 51 until the push rod 53 contacts the separated main ball 11 and pushes the main ball 11 to the input end of the valve body 1, thereby blocking the external pipeline.

[0056] like Figure 2 and Figure 5 As shown, in this embodiment, specifically, the magnet on the driving ring 52 cooperates with the magnet on the push rod 53, and the N poles of half of the magnets on the driving ring 52 face the push rod 53, and the S poles of the other half of the magnets face the push rod 53;

[0057] The magnets on the push rod 53 have N poles of half of the magnets facing the driving ring 52, and S poles of the other half of the magnets facing the driving ring 52;

[0058] Because the drive ring 52 and the push rod 53 are both composed of multiple groups of magnets, when the drive ring 52 rotates, it will drive the push rod 53 to rotate together, so that the push rod 53 can move in the direction limited by the limiting sleeve 51, and then the push rod 53 pushes the detached main ball 11 to resist the input end.

[0059] like Figure 1 As shown, in this embodiment, specifically, the controller 6 is installed outside the valve body 1, and a control panel is installed above the controller 6;

[0060] Therefore, when the device is in use, the various accessories of the valve body 1 can be controlled by the controller 6, and the staff can operate and repair the valve body 1 through the control panel.

[0061] Working principle: when the device is in use, it can be applied to coal petrochemical industry and wind power industry through the valve body 1. When the valve body 1 transmits liquid or gas, it can block the transmission of the input end by itself when leakage occurs, so as to generate more losses before maintenance. When it is used specifically, the input end of the valve body 1 is reinforced by the sealing component 4, and the plugging component 5 of the device can seal the leakage caused by aging at the connection of the valve body 1, so as to reduce the leakage consumption caused by aging when the staff arrives for maintenance. In normal operation, the valve body 1 can adjust the main ball 11 through the magnetic coupling component 2, and can adjust the auxiliary ball 12 through the adjustment component 3, and adjust the valve body 1 at the same time. The node component 3 can also drive the plugging component 5. The main sphere 11 and the auxiliary sphere 12 are respectively provided with flow channels, and the auxiliary sphere 12 is installed in the flow channel of the main sphere 11. At the same time, the main sphere 11 and the auxiliary sphere 12 are concentrically arranged together. Therefore, when the device blocks liquid or gas, even if the main sphere 11 is completely closed, the flow channel of the main sphere 11 can be blocked by quickly rotating the auxiliary sphere 12. Then, by rotating the main sphere 11, the liquid or gas remaining in the flow channel can be discharged. Therefore, when the device is in use, it can speed up the closing and reduce the liquid or gas flowing into the flow channel during closing, and it can block the input pipe after leakage occurs at the connection.

[0062] 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. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
