Description

Technical Field

[0001] The invention relates to the technical field of mechanical connection devices, in particular to a six-way coupling. Background Art

[0002] In the field of industrial automation, three-way control valves are widely used in fluid control and temperature control systems. The valve core shaft of the three-way control valve is usually connected to the electric actuator through a coupling. However, in actual applications, due to the complex on-site pipeline construction, limited space and variable installation conditions, the selection of the three-way control valve often needs to be determined according to the specific conditions of the on-site pipeline.

[0003] At present, the pipeline connection method of the three-way control valve is relatively single and cannot meet the needs of various pipeline layouts. If the actual situation of the on-site pipeline is not fully considered during the design and selection, the three-way control valve may not match the pipeline function. In this case, it is usually necessary to remake the pipeline or rework the three-way control valve, which not only increases the cost, but also prolongs the construction period and even causes disputes. Therefore, there is an urgent need for a device that can flexibly adapt to various pipeline connection requirements to solve the above problems. Summary of the invention

[0006] Preferably, the locking assembly includes a plurality of connecting columns and a driving assembly distributed in a ring shape, the connecting columns penetrate through and are slidably connected to one end of the connecting joint, the driving assembly is used to drive the connecting columns to slide horizontally, a plurality of sliding grooves are provided at one end of the connecting column, and a card block is slidably connected to the inner wall of the sliding groove.

[0007] Preferably, the clamping block is a right trapezoid, and a support spring is fixedly connected to the inner bottom wall of the sliding groove, and the other end of the support spring is fixedly connected to the inner side wall of the clamping block.

[0008] Preferably, a limiting rope is fixedly connected to the inner side wall of the clamping block, the other end of the limiting rope penetrates through the connecting column and is fixedly connected to a fixing ring, and the inner wall of the fixing ring is fixedly connected to the outer wall of the connecting joint.

[0009] Preferably, a pressure sensor is embedded in the side wall of the clamping block, and the pressure sensor is located outside the sliding groove.

[0010] Preferably, the driving assembly includes a threaded groove formed on the surface of the connecting column, and a threaded ring is threadedly connected to the outer wall of the threaded groove, and one end of the threaded ring is rotatably connected to the outer wall of the connecting joint.

[0011] Preferably, an annular tooth groove is formed on the outer side wall of the threaded ring, and the annular tooth groove is meshed with a toothed ring, and one end of the toothed ring is rotatably connected to the outer wall of the connecting joint.

[0012] Preferably, the tooth groove of the toothed ring is meshed with a gear, a driver is fixedly connected to the outer wall of the connecting joint, and the driving end of the driver is fixedly connected to the outer wall of the gear.

[0013] Preferably, the driving coupling includes two clamping plates. Quadrilateral slot one is formed on the upper surface of the two clamping plates, hexagonal slot two is formed on the lower surface of the two clamping plates, mounting holes are respectively formed at the four corners of the two clamping plates, a bolt is disposed through the interior of the mounting hole, and a nut is threadedly connected to the outer wall of the bolt.

[0014] Preferably, four groups of sliding grooves are formed on the outer side wall of one of the clamping plates, a T-shaped anti-loosening member is slidably mounted on the inner wall of the sliding groove, a tension spring is fixedly connected to the outer side wall of the anti-loosening member, the other end of the tension spring is fixedly mounted on the side wall of the sliding groove, a convex layer is disposed on the inner wall of the mounting hole, a groove is formed on the surface of the bolt, and clamping grooves are formed on the surfaces of the bolt and the nut.

[0015] Working principle: The actuator is controlled to rotate by the controller. The actuator drives the valve stem to rotate through the driving coupling. The valve stem drives the valve core to rotate to adjust the flow rate of the valve port. When the valve core rotates, the passages of the inlet port, the bypass port and the cooling port can be switched, realizing six different pipeline connection directions, meeting various installation requirements, improving the installation flexibility, and reducing the rework cost and the cost of pipeline re-production caused by incorrect selection.

[0016] When the valve body is connected to the pipeline joint, the connecting column is passed through the assembly hole of the pipeline joint. When the assembly hole passes through the clamping block, the clamping block can be pressed down along its inclined surface into the inside of the sliding groove, so that the assembly hole can pass through the clamping block normally. After the assembly hole passes through the clamping block, the clamping block slides out of the sliding groove outward under the elastic force of the supporting spring. The controller controls the operation of the driver, the driver drives the gear to rotate, the rotation of the gear drives the toothed ring to rotate, the rotation of the toothed ring drives a plurality of threaded rings to rotate, and the rotation of the threaded rings drives the connecting column to slide horizontally, so that the clamping block will gradually press against the pipeline joint, realizing the rapid docking of the pipeline joint and the connecting joint, and saving installation time.

[0017] When the pipeline joint needs to be disassembled, the controller controls the driver to run in the reverse direction, thereby driving the connecting column to move in the reverse direction, so that the clamping block moves away from the assembly hole. When the clamping block moves to a certain position, it will slide into the inside of the sliding groove under the pulling action of the limiting rope, achieving the effect of automatically contracting the clamping block, so that the pipeline joint can be quickly removed. When installing the drive coupling, insert the actuator shaft into the first slot. After one end of the valve stem is inserted into the second slot, pass the bolt through the installation hole and connect it with the nut to fix the two clamping plates. The drive coupling realizes the transmission connection between the valve stem and the actuator. When the actuator runs, it drives the drive coupling to rotate. The centrifugal force generated when the drive coupling rotates drives the anti-loosening part to slide outward, so that the plug column moves and inserts into the inside of the clamping groove, thereby fixing the bolt and the nut, preventing the nut from loosening due to the vibration generated by the operation of the actuator and affecting the stability of the connection of the drive coupling. And when the bolt is inserted into the installation hole, align the convex layer and insert it into the groove, thereby limiting the bolt, facilitating the plug column to accurately insert into the clamping groove on the surface of the bolt, and realizing the synchronous reinforcement of the bolt and the nut.

[0018] The present invention provides a six-way coupling. It has the following beneficial effects: 1. The present invention can realize six different pipeline connection directions by driving the core to rotate by the actuator, meet various installation requirements, improve installation flexibility, and reduce the costs of rework and pipeline re-production caused by incorrect selection.

[0019] 2. The present invention drives the connecting column to move through the drive assembly, so that the clamping block will gradually press against the pipeline joint, realizing the rapid docking of the pipeline joint and the connecting joint, and saving installation time.

[0020] 3. The drive assembly of the present invention drives the connecting column to move in the reverse direction to make the clamping block move away from the assembly hole, and is received in the sliding groove under the pulling action of the limiting rope, achieving the effect of automatically contracting the clamping block, so that the pipeline joint can be quickly removed, realizing the rapid disassembly and assembly of the valve body.

[0021] 4. In the present invention, the valve stem and the actuator are drivingly connected through a driving coupling. When the driving coupling rotates, the insertion post is inserted into the inside of the card slot under the action of centrifugal force, thereby fixing the bolt and the nut, preventing the nut from loosening due to the vibration generated during the operation of the actuator, and affecting the stability of the connection of the driving coupling.

[0024] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the attached Figure 1 - attachment Figure 4 , an embodiment of the present invention provides a six-way coupling, including a valve body 1 of a three-way with a cavity inside, a valve core 2, a valve rod 3 provided in the valve body 1, and a pipeline joint 9. The inner end of the valve rod 3 is connected to the valve core 2 and its outer end extends outside the valve body 1. An actuator 10 is fixedly connected to the outer side wall of the valve body 1. The actuator 10 selects a high-precision servo motor. A driving coupling 11 is installed between the actuator 10 and the valve rod 3. The driving coupling 11 is used for the transmission connection between the actuator 10 and the valve rod 3. An inlet 4, a bypass port 5, and a cooling port 6 are fixedly provided on the surface of the valve body 1. The cavity inside the valve body 1 is set to be cylindrical. The valve core 2 is set to be an I-shaped block. The outer side wall of the valve core 2 fits the inner wall of the valve body 1. One ends of the inlet 4, the bypass port 5, and the cooling port 6 are respectively fixedly connected with I-shaped connection joints 7. A locking assembly 8 is installed on the surface of the connection joint 7. The locking assembly 8 is used for the quick connection of the connection joint 7 to the pipeline joint 9. A multiple sealing structure combining a metal sealing ring and a rubber sealing ring is provided between the valve cavity and the valve core 2 to improve the sealing performance. The efficient sealing performance ensures the safe operation of the system. The actuator 10 is electrically connected to a controller, and the controller is used to control the opening and closing of the actuator 10.

[0026] Specifically, the pipeline joint 9 is used to connect the engine and the heat exchanger. The actuator 10 drives the valve rod 3 to rotate through the driving coupling 11. The valve rod 3 drives the valve core 2 to rotate to adjust the flow rate of the valve port. And when the valve core 2 rotates as Figure 3 shown, six different pipeline connection directions can be realized, meeting various installation requirements, improving the installation flexibility, and reducing the costs of rework and pipeline re-production caused by incorrect selection. When the valve body 1 is docked with the pipeline joint 9, the pipeline joint 9 is locked through the locking assembly 8, realizing the quick locking and unlocking of the pipeline joint 9, and shortening the installation time.

[0027] Please refer to the attached Figure 6 - attachment Figure 7 , the locking assembly 8 includes a plurality of connecting columns 81 distributed in a ring and a driving assembly 82. The connecting columns 81 penetrate and are slidably connected to one end of the connection joint 7. The driving assembly 82 is used to drive the connecting columns 81 to slide horizontally. A plurality of sliding grooves are opened at one end of the connecting column 81. A clamping block 83 is slidably connected to the inner wall of the sliding groove. The clamping block 83 is set to be a right trapezoid. A support spring 84 is fixedly connected to the inner bottom wall of the sliding groove. The other end of the support spring 84 is fixedly connected to the inner side wall of the clamping block 83. The number of the connecting columns 81 is consistent with the number and position of the assembly holes of the pipeline joint 9.

[0028] Specifically, the support spring 84 is used to push the clamping block 83 out of the sliding groove. During installation, the connecting column 81 is passed through the assembly hole of the pipeline joint 9. When the assembly hole passes through the clamping block 83, the clamping block 83 can be pressed down into the interior of the sliding groove along its inclined surface, enabling the assembly hole to pass through the clamping block 83 normally. After the assembly hole passes through the clamping block 83, the clamping block 83 slides out of the sliding groove outward under the elastic force of the support spring 84. The connecting column 81 is driven to move by the driving assembly 82, causing the connecting column 81 to drive the clamping block 83 to slide, so that the clamping block 83 will gradually press against the pipeline joint 9, realizing the rapid docking of the pipeline joint 9 and the connecting joint 7 and saving the installation time.

[0029] Please refer to the appendix Figure 6 , a limiting rope 86 is fixedly connected to the inner side wall of the clamping block 83. The other end of the limiting rope 86 penetrates through the connecting column 81 and is fixedly connected with a fixing ring 87. The inner wall of the fixing ring 87 is fixedly connected to the outer wall of the connecting joint 7.

[0030] Specifically, the fixing ring 87 is used to fix the limiting rope 86. When it is necessary to disassemble the pipeline joint 9, the driving assembly 82 drives the connecting column 81 to move in the reverse direction, causing the clamping block 83 to move away from the assembly hole. When the clamping block 83 moves to a certain position, it will slide into the interior of the sliding groove under the pulling action of the limiting rope 86, achieving the effect of automatically contracting the clamping block 83, so that the pipeline joint 9 can be quickly removed.

[0031] Please refer to the appendix Figure 8 , the driving assembly 82 includes a threaded groove 821 opened on the surface of the connecting column 81. The outer wall of the threaded groove 821 is threadedly connected with a threaded ring 822. One end of the threaded ring 822 is rotatably connected to the outer wall of the connecting joint 7. An annular tooth groove is opened on the outer side wall of the threaded ring 822, and the annular tooth groove is meshed with a tooth ring 823. One end of the tooth ring 823 is rotatably connected to the outer wall of the connecting joint 7. The tooth groove of the tooth ring 823 is meshed with a gear 824. A driver 18 is fixedly connected to the outer wall of the connecting joint 7. The driving end of the driver 18 is fixedly connected to the outer wall of the gear 824. The driver 18 is electrically connected to the driver 18.

[0032] Specifically, when it is necessary to drive the connecting column 81 to slide, the driver 18 is controlled to operate through the controller. The driver 18 drives the gear 824 to rotate. The rotation of the gear 824 drives the tooth ring 823 to rotate. The rotation of the tooth ring 823 drives a plurality of threaded rings 822 to rotate. The rotation of the threaded rings 822 drives the connecting column 81 to slide horizontally, realizing the synchronous sliding of multiple groups of connecting columns 81 and achieving rapid installation. Moreover, by adjusting the rotation direction of the driver 18, the sliding direction of the connecting column 81 can be adjusted to meet the rapid disassembly and assembly requirements of the valve body 1 and the pipeline joint 9.

[0033] Please refer to the appendix Figure 7, a pressure sensor 85 is embedded and connected to the side wall of the clamping block 83. The pressure sensor 85 is located outside the sliding groove, and the pressure sensor 85 is electrically connected to the controller.

[0034] Specifically, when fixing the pipeline joint 9, the pressure sensor 85 on one side of the clamping block 83 abuts against the pipeline joint 9. The pressure between the pipeline joint 9 and the connecting joint 7 can be detected through the pressure sensor 85. When the value detected by the pressure sensor 85 reaches a predetermined threshold, the controller controls the driver 18 to stop running, avoiding deformation of the pipeline joint 9 and the connecting joint 7 at the port due to excessive extrusion pressure.

[0035] Please refer to the appendix Figure 3 - appendix Figure 9 , the drive coupling 11 includes two clamping plates 111. A quadrilateral slot one 112 is opened on the upper surface of the two clamping plates 111. A hexagonal slot two 113 is opened on the lower surface of the two clamping plates 111. Mounting holes 14 are respectively opened at the four corners of the two clamping plates 111. A bolt 12 is penetrated through the inside of the mounting hole 14, and a nut 13 is threadedly connected to the outer wall of the bolt 12.

[0036] Specifically, the slot one 112 is used for inserting the rotating shaft of the actuator 10, and the slot two 113 is used for inserting the valve stem 3. When installing the drive coupling 11, after inserting the rotating shaft of the actuator 10 into the slot one 112 and inserting one end of the valve stem 3 into the slot two 113, the bolt 12 is passed through the mounting hole 14 and connected to the nut 13 to fix the two clamping plates 111, realizing the transmission connection between the valve stem 3 and the actuator 10 through the drive coupling 11.

[0037] Please refer to the appendix Figure 10 , four groups of sliding grooves 114 are opened on the outer side wall of one of the clamping plates 111. The sliding grooves 114 are installed on one side of the nut 13. A T-shaped anti-loosening part 115 is slidably connected and mounted on the inner wall of the sliding groove 114. A tension spring 116 is fixedly connected to the outer side wall of the anti-loosening part 115, and the other end of the tension spring 116 is fixedly installed on the side wall of the sliding groove 114. A convex layer 15 is arranged on the inner wall of the mounting hole 14, a groove 16 is opened on the surface of the bolt 12, and a clamping groove 17 is opened on the surfaces of both the bolt 12 and the nut 13. The anti-loosening part 115 includes a sliding seat, and a plug post is fixedly connected to one side of the sliding seat. The plug post is used for inserting into the clamping groove 17.

[0038] Specifically, when the drive coupling 11 is installed, the anti-loosening member 115 is pulled by the tension spring 116, so that the anti-loosening member 115 is away from the mounting hole 14, avoiding affecting the normal installation of the nut 13. After the bolt 12 is tightened, the insertion post is aligned with the card slot 17. When the drive coupling 11 rotates, the centrifugal force generated drives the anti-loosening member 115 to slide outward, so that the insertion post moves into the interior of the card slot 17, thereby fixing the bolt 12 and the nut 13, preventing the nut 13 from loosening due to the vibration generated by the operation of the actuator 10, and affecting the stability of the connection of the drive coupling 11. And in order for the insertion post to accurately dock with the card slot 17 on the surface of the bolt 12, when the bolt 12 is inserted into the mounting hole 14, the convex layer 15 is aligned with and inserted into the groove 16, thereby positioning the bolt 12, facilitating the accurate insertion of the insertion post into the card slot 17 on the surface of the bolt 12, and realizing the synchronous reinforcement of the bolt 12 and the nut 13.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
