Description

Technical Field

[0001] The invention relates to the technical field of flow distribution rotary valves, in particular to a valve core rotating flow distribution rotary valve device. Background Art

[0002] A flow distribution valve is a valve device used to control the distribution and flow direction of fluid (liquid or gas). It plays a key role in various fluid systems. It can guide the fluid from one or more inlets to one or more outlets according to the needs of the system, and can adjust the flow rate and flow direction.

[0003] Flow distribution rotary valves generally include valve core rotation type flow distribution rotary valves, sliding valve type flow distribution rotary valves and ball valve type flow distribution rotary valves. The valve core rotation type flow distribution rotary valves mainly include butterfly valves. The main structure is that there is a fluid channel inside the valve body. The valve core is installed in the valve body and can rotate around the axis. The operating mechanism is used to control the rotation of the valve core. When the valve core is at different rotation angles, the channel on the valve core and the channel on the valve body will have different connection methods, thereby changing the flow direction and flow distribution of the fluid.

[0004] The prior art publication number is CN103759026A, which provides a butterfly valve, including a valve body, a valve seat, a valve stem, and a valve disc. The performance of the butterfly valve is improved in the following aspects: 1. By dividing the valve disc into two parts and providing a pressure relief hole, the valve disc is pressure-relieved before the overall rotation and is opened in steps, so that the opening pressure of the butterfly valve is relatively small and more labor-saving; 2. By adopting titanium material and introducing a fluoroplastic layer, the corrosion resistance of the butterfly valve is greatly improved; 3. The dustproof performance of the butterfly valve is improved by providing a dustproof ring; 4. The sealing performance of the butterfly valve is improved by providing a sealing belt, so that the butterfly valve has better comprehensive performance.

[0005] In the above-mentioned prior art, although the butterfly valve core is divided into two petals, the two petals cannot rotate freely. If two sets of diversion pipes are installed on the rear side of the main pipe, the device cannot play a good diversion role and adjust the flow of the corresponding diversion pipes. In addition, in some use occasions, such as the mixing and preparation process in the food and beverage industry, in order to make different raw materials (such as juice, syrup, additives, etc.) mix evenly, the valve core installed on each raw material delivery pipe needs to be continuously rotated to produce a changing fluid flow state, which helps to break the laminar flow state of the fluid and achieve a better mixing effect. However, the existing flow distribution rotary valve cannot make the valve core rotate continuously, and the use occasions are limited.

[0006] It can be seen that a valve core rotating flow distribution rotary valve device is needed to solve the problems mentioned in the above background technology that the valve core of the existing flow distribution rotary valve cannot rotate freely in the split state, adjust the flow of the corresponding diversion pipeline, and cannot make the valve core rotate continuously to adapt to more usage occasions.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 11 A valve core rotary flow distribution rotary valve device includes a main pipeline 1, a rotary valve core 2 is installed inside the main pipeline 1, and the rotary valve core 2 includes a main shaft 201, a first sleeve shaft 202 and a second sleeve shaft 203, the first sleeve shaft 202 is connected to a first valve flap 3, and the second sleeve shaft 203 is connected to a second valve flap 4, the first valve flap 3 and the second valve flap 4 rotate around the main shaft 201, and the main shaft 201 rotates inside the main pipeline 1, the first sleeve shaft 202 and the second sleeve shaft 203 are respectively connected to a group of valve flap driving components 6, the rotation angle of the first valve flap 3 and the second valve flap 4 is controlled by the valve flap driving component 6, and the valve flap driving component 6 includes a first bevel gear 601 and a second bevel gear 601 meshing with each other. 602, and a chuck 603 is provided on the rear side of the second bevel gear 602, and a plurality of groups of slots 6032 are equidistantly provided on the chuck 603, and the slots 6032 are in an interval-engaged relationship with the rotating second clamping column 6071, one side of the second clamping column 6071 is connected to the front side disk 607, and the front side disk 607 is arranged on the rear side of the convex disk 606, and a lever 6043 in contact with the convex disk 606 is provided below the convex disk 606, and the lever 6043 is arranged on one side of the rotating disk 604, and the other side of the rotating disk 604 is connected to the first clamping column 6042, and the first clamping column 6042 is also in an interval-engaged relationship with the slots 6032, and the bottom end of one side of the first clamping column 6042 is connected to the bottom spring 605.

[0024] In this embodiment, the first sleeve shaft 202 and the second sleeve shaft 203 are spaced apart on the outside of the main shaft 201, and the multiple sets of first sleeve shafts 202 spaced apart are all connected to the first valve flap 3, and the multiple sets of second sleeve shafts 203 spaced apart are all connected to the second valve flap 4, so the rotation of the first sleeve shaft 202 and the second sleeve shaft 203 around the main shaft 201 is the rotation of the first valve flap 3 and the second valve flap 4 around the main shaft 201, and this rotation process can only be in one direction, because there are mutually engaged sliding blocks 2013 and inner ratchet 2021, and a sealing structure is provided at the edge of the first valve flap 3 and the second valve flap 4 A corresponding sealing structure can also be provided inside the main pipeline 1. Corresponding sealing structures are provided at the positions where the main shaft 201, the first sleeve shaft 202 and the second sleeve shaft 203 pass through the main pipeline 1, so that the sealing of the device is reliable. The upper end of the first sleeve shaft 202 passes through the top of the main pipeline 1 and is connected to the main shaft drive assembly 5, while the second sleeve shaft 203 passes through the main pipeline 1 at the bottom and is connected to the main shaft drive assembly 5 located below the main pipeline 1. Therefore, the angle between the first valve flap 3 and the second valve flap 4 needs to be adjusted separately, or one group of flaps can be fixed and the other group can be rotated to adjust the angle between the two.

[0025] Specifically, the main pipeline 1 is hollow inside, and the tail end of the main pipeline 1 is connected to the first diversion pipeline 101 and the second diversion pipeline 102 through a pipeline connecting device, and a baffle is provided at the tail end of the main pipeline 1 near the connection between the first diversion pipeline 101 and the second diversion pipeline 102, and the shape of the baffle matches the arc part of the first valve flap 3 or the second valve flap 4.

[0026] In this embodiment, the baffle is matched with the first valve flap 3 and the second valve flap 4 so that the first valve flap 3 and the second valve flap 4 can rotate at an angle of ninety degrees. One group can be matched with the baffle to prevent one group of diversion pipes from being allocated flow, allowing the other group to receive all the flow of the main pipeline 1, thereby achieving the purpose of opening one of the first diversion pipe 101 and the second diversion pipe 102. A sealing sheet can be set on the edge of the baffle to cooperate with the first valve flap 3 and the second valve flap 4 to achieve a better control effect.

[0027] Specifically, the main shaft 201 passes through the main pipe 1 and extends to its outside, and the outside of the main shaft 201 is fixedly connected with a fixed block 2011 and a fixed spring 2012, the internal sliding connection of the fixed block 2011 is connected to a sliding block 2013, and the bottom of the sliding block 2013 is connected to the fixed spring 2012, the inner ring of the first sleeve shaft 202 is connected with an inner ratchet 2021, and the inner ratchet 2021 and the sliding block 2013 match, the second sleeve shaft 203 and the first sleeve shaft 202 have the same structure and are both in multiple groups, and the multiple groups of first sleeve shafts 202 and second sleeve shafts 203 are arranged at intervals on the outside of the main shaft 201.

[0028] In this embodiment, the relationship between the sliding block 2013 and the inner ratchet 2021 is the relationship between the inner ratchet pawl. Only when rotating in one direction can the main shaft 201 drive the first sleeve shaft 202 to rotate. Otherwise, rotating the main shaft 201 in the opposite direction will only cause the sliding block 2013 to bounce continuously, and the inner ratchet 2021 cannot be engaged, and the first sleeve shaft 202 or the second sleeve shaft 203 cannot be driven to rotate. The engagement direction of the sliding block 2013 and the inner ratchet 2021 needs to match the water flow direction, so that when the water flows through, the outer first sleeve shaft 202 and the second sleeve shaft 203 are engaged with the outer side of the main shaft 201 through the inner ratchet 2021 and cannot rotate independently, so that the first valve flap 3 and the second valve flap 4 will not rotate along the water flow direction. In addition, a structure to prevent reversal is also provided in the valve flap drive assembly 6, so the water flow cannot drive the first sleeve shaft 202 and the second sleeve shaft 203 to rotate.

[0029] Specifically, the second bevel gear 602 and the chuck 603 are connected by a shaft, and the chuck 603 includes a disk body 6031 and a slot 6032, the slot 6032 is equidistantly arranged at the edge of the disk body 6031, and the second clamping column 6071 matches the slot 6032, the first clamping column 6042 matches the slot 6032, and the first clamping column 6042 is located below the slot 6032.

[0030] In this embodiment, when the motor 501 is started and needs to drive the main shaft 201 to rotate, it will drive the first sleeve shaft 202 and the second sleeve shaft 203 to rotate together, so it is necessary to disconnect the structure to prevent reversal in the valve disc drive assembly 6, that is, to make the cam 606 and the front side plate 607 move laterally together on the through shaft and break away from the connection relationship with the lever 6043. Without the activation of the second clamping column 6071 and the connection relationship with the lever 6043, the chuck 603 can rotate freely.

[0031] Specifically, the convex disc 606 includes a large arc portion and a small arc portion, and the large arc portion and the small arc portion are integrally formed. The large arc portion is longer than the small arc portion at the center diameter of the convex disc 606, and both the large arc portion and the small arc portion are in contact with the lever 6043. The rear side of the convex disc 606 is connected to the crank 608 through an axis, and a limiting groove is provided on the outer side of the axis. Limiting blocks matching the limiting groove are provided inside the convex disc 606 and the front side disc 607, and the convex disc 606 and the front side disc 607 can move on the axis.

[0032] In this embodiment, there is a drop between the large arc portion and the small arc portion of the convex disk 606. When rotating, there will be a drop when rotating from the large arc portion to the small arc portion, or from the small arc portion to the large arc portion, so that the lever 6043 in contact with it rotates to a certain extent with the main disk 6041 as the center, which will drive the first clamping column 6042 at the other end of the main disk 6041 to rotate to a certain extent, and the first clamping column 6042 enters the corresponding clamping groove 6032 to temporarily clamp it. The first clamping column 6042 is separated from the clamping groove 6032 as the second clamping column 6071 continues to be pushed. When the second clamping column 6071 enters the inside of the clamping groove 6032, the first clamping column 6042 is separated from the clamping groove 6032. When the second clamping column 6071 is separated from the clamping groove 6032, the first clamping column 6042 contacts the clamping groove 6032, so that the clamping disk 603 cannot rotate freely and can only rotate through the driving force of the crank 608 to prevent reversal caused by water flow pressure.

[0033] Specifically, the rotating disk 604 includes a main disk 6041, a first clamping column 6042 and a lever 6043, and the main disk 6041 is located between the first clamping column 6042 and the lever 6043, the main disk 6041 and the first clamping column 6042 and the lever 6043 are all connected by a connecting arm, and a fixed block is installed on the rear side of the main disk 6041, the main disk 6041, the first clamping column 6042, the lever 6043 and the connecting arm are integrally formed, and the main disk 6041 rotates on one side of the fixed block.

[0034] In this embodiment, a vertical plate is provided on one side of the installation compartment for installing the main shaft drive assembly 5 and the valve flap drive assembly 6. The vertical plate is located on one side of the crank 608. A slot for fixing the crank 608 can be provided on the vertical plate so that the crank 608 can be fixed when there is no need to control the rotation of the crank 608.

[0035] Specifically, a bottom spring 605 is provided at the bottom end of the connecting arm between the main disk 6041 and the first clamping column 6042 , and the other end of the bottom spring 605 is fixed to the outside of the main pipe 1 .

[0036] In this embodiment, a scale can also be set on the vertical plate to allow the operator to know the degree of rotation of the first valve flap 3 or the second valve flap 4 below when rotating the crank 608, so that the user can more accurately know the degree of rotation of the first valve flap 3, the second valve flap 4 and the degree between the two.

[0037] See also Figure 1-Figure 7 , a valve core rotating flow distribution rotary valve device, the top end of the main shaft 201 is connected to the main shaft driving component 5, and the rotation of the main shaft 201 is controlled by the main shaft driving component 5.

[0038] In this embodiment, a controller is installed in the device, and the controller can control the electronic components in the device, such as the motor 501, to start or shut down. When the spindle drive assembly 5 is replaced to rotate the valve core, the working mode of the device is changed, so it is very likely that the use environment has been changed. Compared with manually controlling the rotation of the first valve flap 3 and the second valve flap 4, using the spindle drive assembly 5 to control the rotation of the valve core is more suitable for use in an environment with low flow pressure.

[0039] Specifically, the spindle drive assembly 5 includes a motor 501, and the output end of the motor 501 is connected to a drive shaft 502, one end of the drive shaft 502 is connected to a fixed tube 506, and the outer side of the fixed tube 506 is sleeved with a sleeve 505, a movable gear 504 is connected below the sleeve 505, a driven gear 503 is arranged below the movable gear 504, and a cavity is arranged inside the driven gear 503, and internal teeth are arranged inside the cavity, and the internal teeth and the movable gear 504 are meshed, a connecting spring 507 is connected to the outer side of the fixed tube 506, and the top of the connecting spring 507 is connected to the fixed top 508, a hinged rod 509 is hinged on the outer side of the sleeve 505, and a handle 510 is connected to one end of the hinged rod 509.

[0040] In this embodiment, when the motor 501 needs to drive the main shaft 201 to rotate continuously, it is generally used in pipelines with low flow pressure. The main shaft 201 can drive the first sleeve shaft 202 and the second sleeve shaft 203 to rotate. The cooperation between the sliding block 2013 and the inner ratchet 2021 enables the valve core to be sufficient to cope with a lower pressure use environment when the valve core rotates as a whole. This process can be achieved by increasing the stiffness of the fixed spring 2012 and the sliding block 2013 and the inner ratchet 2021 to achieve the purpose of use in special scenarios. The main shaft 201 drives the first valve flap 3 and the second valve flap 4 to rotate slowly inside the main pipeline 1. At this time, the angle between the first valve flap 3 and the second valve flap 4 can be adjusted to 180 degrees.

[0041] Specifically, an articulated seat is provided on the outer side of the sleeve 505, and the sleeve 505 is connected to the articulated rod 509 through the articulated seat, an installation bin is provided on the outer side of the main shaft drive assembly 5 and the valve disc drive assembly 6, and the installation bin is located at the top and bottom ends of the main pipeline 1, the articulated rod 509 penetrates the installation bin and extends to the outside thereof, the handle 510 is located on the outside of the installation bin, and a hinge shaft is provided between the handle 510 and the installation bin, and a locking block is connected to the outer side of the handle 510.

[0042] In this embodiment, the locking block can be a circular structure and made of rubber material. A plurality of groups of engaging holes at different positions are arranged on the outside of the installation bin. When one end of the handle 510 is rotated with the hinge seat as the center, the hinge rod 509 at the other end will drive the sleeve 505 to move in the opposite direction. At this time, if no adjustment is required, the locking block can be engaged with the engaging hole at the corresponding position to complete the fixation. When it needs to be released, it can be pulled out.

[0043] Specifically, a plurality of groups of card holes are provided on the outer side of the installation bin, and the card holes match the card blocks.

[0044] In this embodiment, a through hole is provided inside the fixed top 508 to facilitate the penetration of the driving shaft 502. The driving shaft 502 also penetrates the connecting spring 507 and extends to one end of the sleeve 505. The fixed top 508 can be fixed inside the installation bin by a fixing block. The connecting spring 507 is fixed to one end of the fixed top 508. In this way, when the driving shaft 502 rotates, it will penetrate the fixed top 508 and the connecting spring 507 to drive the sleeve 505 to rotate without affecting the fixed top 508 and the connecting spring 507. An annular groove is provided on the outer protrusion of the sleeve 505 to facilitate the fixation of the connecting spring 507, so that when the sleeve 505 rotates, the connecting spring 507 is located in the annular groove and does not rotate. The sleeve 505 can be relatively fixedly installed inside the installation bin and only rotates but does not move. The movable gear 504 penetrates the interior of the sleeve 505 and moves inside.

[0045] When in use, if the valve core does not need to rotate as a whole inside the main pipe 1, the handle 510 can be controlled to make the hinged rod 509 drive the sleeve 505 and the movable gear 504 to move, and the sleeve 505 moves inside the fixed pipe 506, and the movable gear 504 is disengaged from the internal teeth of the driven gear 503, so that the movable gear 504 and the driven gear 503 will lose the connection relationship, and the main shaft 201 will not be driven to rotate regardless of whether the motor 501 is started or not. If the valve core needs to rotate inside the main pipe 1, the handle 510 can be controlled to drive the hinged rod 509 to make a movement opposite to the above, so that the movable gear 504 moves The movable gear 504 meshes with the internal teeth of the driven gear 503. Therefore, when the motor 501 is started, the fixed tube 506, the sleeve 505 and the movable gear 504 are driven to rotate through the driving shaft 502, and then the driven gear 503 is driven to rotate, which will drive the main shaft 201 to rotate. In this process, because the sliding block 2013 and the inner ratchet 2021 are in a clamping state, the main shaft 201 will drive the first sleeve shaft 202 and the second sleeve shaft 203 on the outside to rotate together, which will drive the first valve flap 3 and the second valve flap 4 to rotate together, so that the valve core rotates as a whole inside the main pipeline 1. When it is necessary to adjust the angle between the first valve flap 3 and the second valve flap 4 to control the flow rate of the first shunt pipe 101 and the second shunt pipe 102, the crank 608 can be manually rotated to make the crank 608 drive the convex plate 606 and the front side plate 607 to rotate. When the front side plate 607 rotates, the second clamping column 6071 will be driven to rotate, and will enter the clamping groove 6032 during the rotation process. As the second clamping column 6071 continues to rotate, the disk body 6031 will be driven to rotate. In this process, the convex plate 606 rotates so that the contact part with the lever 6043 changes from a large arc part to a small arc part. There is a drop between the two. The lever 6043 will rotate around the main plate 6041 to a certain extent, and the main plate 6041 will rotate to a certain extent. The first clamping column 6042 on the other side of the disk 6041 will also rotate due to the rotation of the main disk 6041, so that the first clamping column 6042 enters the corresponding clamping groove 6032 and engages. The first clamping column 6042 cooperates with the second clamping column 6071 to prevent the rotating chuck 603 from reversing. The rotation of the chuck 603 drives the second bevel gear 602 to rotate, and then drives the first bevel gear 601 to rotate, thereby driving the first sleeve shaft 202 to rotate around the main shaft 201, so that the first valve flap 3 rotates around the main shaft 201. The adjustment process of the second valve flap 4 is the same as that of the first valve flap 3. The purpose of adjusting the main pipe flow, the shunt pipe flow, and opening and closing the pipeline can be achieved by adjusting the rotation angle of the first valve flap 3 and the second valve flap 4.
