Compared with the method of using two control valves to control the material flow direction in related technologies, the control difficulty and equipment cost are reduced, and the integration degree is high, reducing the space occupation and making it suitable for installation and use in small spaces.

[0041] The following is combined ​ This invention describes a pneumatic conveying three-way material distribution valve.

[0042] An embodiment of this utility model provides a pneumatic conveying three-way material distribution valve, including a valve body 100, a valve core 200, and a rotation drive device.

[0043] The valve body 100 has a closed chamber inside. It is provided with an inlet, a first outlet and a second outlet. The inlet, the first outlet and the second outlet are all connected to the chamber inside the valve body 100 to realize the connection between the inlet and the first outlet and the second outlet.

[0044] The valve core 200 is disposed in a closed chamber inside the valve body 100 and is rotatably connected to the valve body 100. The rotation drive device can be disposed outside the valve body 100 and is connected to the valve core 200 inside the valve body 100 for driving the valve core 200 to rotate between a first position and a second position.

[0045] When the valve core 200 rotates to the first position, the valve core 200 connects the feed port and the first discharge port, while blocking the second discharge port. At this time, the material enters the valve body 100 through the feed port and is discharged through the first discharge port.

[0046] When the valve core 200 rotates to the second position, the valve core 200 connects the inlet and the second outlet, while blocking the first outlet. At this time, the material enters the valve body 100 through the inlet and is discharged through the second outlet.

[0047] The pneumatic conveying three-way distribution valve provided by the utility model adopts the mode of setting a valve core 200 in a valve body 100 and driving the valve core 200 to rotate by using a rotary driving device, realizes only the first discharge port discharging or only the second discharge port discharging, further changes the material conveying direction effect, compared with the mode of using two control valves to control the material flow direction in the related art, the control difficulty and equipment cost are reduced, and the degree of integration is high, the space occupation is reduced, and the utility model is suitable for small space installation and use.

[0048] In some embodiments, the valve body 100 can include a cylinder body 110, a top cover 120 and a bottom cover 130, the top cover 120 and the bottom cover 130 are detachably connected to the top and bottom of the cylinder body 110, and when the top cover 120 and the bottom cover 130 are connected to the cylinder body 110, a closed cylindrical chamber is formed in the cylinder body 110.

[0049] The above-mentioned feed inlet, first discharge port and second discharge port are all arranged on the outer peripheral surface of the cylinder body 110 and are all communicated between the inside and outside of the cylinder body 110.

[0050] Specifically, the axes of the feed inlet, the first discharge port and the second discharge port can be located on the same plane, and the plane is perpendicular to the axis of the cylinder body 110, the included angle between the axis of the feed inlet and the axis of the first discharge port can be 150 degrees, the included angle between the axis of the feed inlet and the axis of the second discharge port can be 150 degrees, and the included angle between the axis of the first feed inlet and the axis of the second feed inlet can be 60 degrees.

[0051] A plurality of threaded holes are arranged on the top end surface of the cylinder body 110, a plurality of bolt holes are arranged on the top cover 120, the number of the bolt holes on the top cover 120 is equal to the number of the threaded holes on the top end of the cylinder body 110, and when connected, the plurality of bolt holes of the top cover 120 are aligned with the plurality of threaded holes on the top end of the cylinder body 110, and the connection is completed by using bolts.

[0052] Similarly, the connection mode of the bottom end surface of the cylinder body 110 and the bottom cover 130 is the same as the connection mode of the top end surface of the cylinder body 110 and the top cover 120, which will not be described here.

[0053] The valve core 200 can be a cylindrical structure, the outer diameter of the valve core 200 is equal to the inner diameter of the cylinder body 110, so that when the valve core 200 is located in the cylinder body 110, the axis of the valve core 200 is collinear with the axis of the cylinder body 110, and the outer surface of the valve core 200 is in sliding contact with the inner surface of the cylinder body 110, so that the valve core 200 can rotate in the cylinder body 110 while having a certain sealing ability. A material passage 210 penetrating the valve core 200 is arranged on the valve core 200, and the material passage 210 can penetrate the valve core 200 in a direction perpendicular to the axis of the valve core 200.

[0054] When the valve core 200 is rotated to the first position, the material passage 210 of the valve core 200 is communicated with the first outlet, and the outer side surface of the valve core 200 blocks the second outlet, so that the material entering the valve body 100 from the inlet can only pass through the material passage 210 of the valve core 200 to enter the first outlet, and then be discharged through the first outlet.

[0055] When the valve core 200 is rotated to the second position, the material passage 210 of the valve core 200 is communicated with the second outlet, and the outer side surface of the valve core 200 blocks the first outlet, so that the material entering the valve body 100 from the inlet can only pass through the material passage 210 of the valve core 200 to enter the second outlet, and then be discharged through the second outlet.

[0056] In some embodiments, the first sealing groove is arranged on the top and bottom of the outer side surface of the valve core 200, and the cross section of the first sealing groove can be arc-shaped or rectangular, and the first sealing ring is arranged in the first sealing groove, and the first sealing ring can be made of rubber or silicone.

[0057] In this way, the first sealing ring can be pressed between the outer side surface of the valve core 200 and the inner side surface of the cylinder body 110, so as to prevent the powder or gas material passing through the valve core 200 from leaking into the gap between the valve core 200 and the valve body 100.

[0058] Alternatively, the second sealing ring 220 is arranged on the top and bottom of the valve core 200, and the outer diameter of the second sealing ring 220 is greater than the inner diameter of the valve core 200.

[0059] Specifically, the second sealing ring 220 is connected to the top and bottom of the valve core 200 through the compression ring 240, the outer diameter of the compression ring 240 is equal to the outer diameter of the valve core 200, a plurality of threaded holes are arranged on the top and bottom of the valve core 200, and a plurality of bolt holes penetrating the second sealing ring 220 are arranged on the second sealing ring 220 and the compression ring 240.

[0060] When the second sealing ring 220 is installed on the top of the valve core 200, the second sealing ring 220 is placed on the top of the valve core 200, the bolt holes of the second sealing ring 220 are aligned with the threaded holes on the top of the valve core 200, then the compression ring 240 is placed on the top of the second sealing ring 220, the bolt holes on the compression ring 240 are aligned with the plurality of bolt holes on the second sealing ring 220, and finally the second sealing ring 220 is compressed between the compression ring 240 and the top of the valve core 200 by using the bolts to pass through the bolt holes and connect with the threaded holes.

[0061] The method for installing the second sealing ring 220 on the bottom of the valve core 200 is the same as that for installing the second sealing ring 220 on the top of the valve core 200, which will not be described here.

[0062] Since the outer diameter of the second sealing ring 220 is slightly larger than the outer diameter of the valve core 200, the edge of the second sealing ring 220 is pressed against the inner side of the valve body 100 to prevent the powder or gas material passing through the valve core 200 from leaking into the gap between the valve core 200 and the valve body 100.

[0063] The compression ring 240 can be a flange, and the pressure of the compression ring 240 on the second sealing ring 220 can be adjusted by bolts to adjust the deformation degree of the second sealing ring 220, thereby adjusting the sealing effect of the second sealing ring 240 and prolonging the service life.

[0064] In some embodiments, at least two sealing strips 230 are embedded in the outer side of the valve core 200, and the extension directions of the sealing strips 230 are parallel to the axis of the valve core 200. When the valve core 200 is in the first position, at least two sealing strips 230 are located on both sides of the second discharge port, and when the valve core 200 is in the second position, at least two sealing strips 230 are located on both sides of the first discharge port.

[0065] Specifically, at least two second sealing grooves are arranged on both sides of the region of the valve core 200 for blocking the first discharge port and the second discharge port, and the sealing strips 230 are arranged in the second sealing grooves. After the sealing strips 230 are inserted into the second sealing grooves, the sealing strips 230 protrude from the second sealing grooves by a distance, and when the valve core 200 is installed into the valve body 100, the sealing strips 230 are completely pressed into the second sealing grooves, so that the sealing strips 230 are tightly pressed against the inner wall of the valve body 100.

[0066] In this way, the sealing strips 230 can seal the blocked first discharge port or the second discharge port to prevent the material at the open first discharge port or the second discharge port from entering the blocked second discharge port or the first discharge port through the gap between the valve core 200 and the valve body 100.

[0067] In a preferred embodiment, three second sealing grooves are arranged on the outer side of the valve core 200, two of which are arranged in the region for blocking the first discharge port and the second discharge port, and the other one is arranged in the region on the outer side of the valve core 200 opposite to the region for blocking the first discharge port and the second discharge port. In this way, when the sealing strips 230 are arranged in the three second sealing grooves, the balance of the valve core 200 can be ensured to prevent the eccentric rotation of the valve core 200.

[0068] Further, the cross section of the second sealing groove can be trapezoidal, and the large end of the trapezoid faces inward. In this way, when the sealing strip 230 is inserted into the second sealing groove, the radial movement of the sealing strip 230 along the valve core 200 can be limited.

[0069] The material of the sealing strip 230 can be polytetrafluoroethylene.

[0070] The pneumatic conveying three-way distribution valve can convey powder or gas materials due to the sealing structure arranged in the pneumatic conveying three-way distribution valve.

[0071] In some embodiments, the pneumatic conveying three-way distribution valve further comprises a frame 300, and the valve body 100 is detachably connected to the frame 300 through the bottom cover 130.

[0072] For example, the frame 300 is provided with a mounting plate, and a plurality of bolt holes penetrating the mounting plate are arranged on the mounting plate; when the valve body 100 is placed on the mounting plate, the plurality of bolt holes on the bottom cover 130 of the valve body 100 are aligned with the plurality of bolt holes on the mounting plate; the bolts for fixing the bottom cover 130 and the cylinder body 110 first pass through the bolt holes on the mounting plate and then pass through the bolt holes on the bottom cover 130, and finally are screwed with the threaded holes at the bottom of the cylinder body 110, so as to realize the connection between the valve body 100 and the mounting plate.

[0073] The rotating driving device comprises a motor 410, a transmission mechanism and a first rotating shaft 440; the first rotating shaft 440 penetrates the mounting plate of the frame 300 from the center of the mounting plate upward, then continues to penetrate the bottom cover 130 upward, and finally, the top end of the first rotating shaft 440 is connected with the bottom surface of the valve core 200; at this time, the axis of the first rotating shaft 440 is collinear with the axis of the valve core 200.

[0074] The main body of the motor 410 is connected with the frame 300; a transmission mechanism is arranged between the output shaft of the motor 410 and the end of the first rotating shaft 440 located outside the valve body 100; the transmission mechanism is used for transmitting the power of the motor 410 to the valve core 200, and then driving the valve core 200 to rotate.

[0075] Further, the transmission mechanism can be a gear mechanism; a driving gear 420 is arranged on the output shaft of the motor 410; a driven gear 430 is arranged on the end of the first rotating shaft 440 located outside the valve body 100; the driving gear 420 is engaged with the driven gear 430; when the output shaft of the motor 410 drives the driving gear 420 to rotate, the driving gear 420 drives the driven gear 430 to rotate; the driven gear 430 drives the first rotating shaft 440 connected therewith to rotate, and then drives the valve core 200 to rotate.

[0076] Alternatively, the rotating driving device can further comprise a linear extension device 510, a second rotating shaft 530 and a swing arm 520.

[0077] The connection mode of the second rotating shaft 530 with the valve core 200 is the same as the connection mode of the first rotating shaft 440 with the valve core 200, and will not be described here.

[0078] The linear telescopic device 510 can be an electric push rod, the main body of which is rotationally connected with the frame 300, and the rotation axis is parallel to the rotation axis of the valve core 200. One end of the swing arm 520 is connected with the end of the second rotation shaft 530 located outside the valve body 100, and the other end of the swing arm 520 extends along the radial direction of the second rotation shaft 530, and the end is rotationally connected with the moving end of the electric push rod, and the rotation axis is parallel to the rotation axis of the valve core 200.

[0079] When the electric push rod is telescoped, the swing arm 520 is swung, the swing arm 520 drives the second rotation shaft 530 to rotate, and then drives the valve core 200 to rotate.

[0080] Of course, the linear telescopic device 510 can also be a cylinder or the like.

[0081] Alternatively, the above-mentioned rotation driving device can also include a rotary cylinder 710 and a third rotation shaft 720, the top end of the third rotation shaft 720 passes through the center of the mounting plate upwardly, then continues to pass through the bottom cover 130 upwardly, and finally, the top end of the third rotation shaft 720 is connected with the bottom surface of the valve core 200, at this time, the axis of the third rotation shaft 720 is collinear with the axis of the valve core 200.

[0082] The cylinder body of the rotary cylinder 710 can be connected at the bottom of the mounting plate, the rotary part of the rotary cylinder 710 is provided with a rectangular recess, the axis of the rectangular recess is collinear with the rotation axis of the rotary part, and the third rotation shaft 720 is provided with a rectangular shaft head at the end located outside the valve body 100, the rectangular shaft head is inserted into the rectangular recess, so that the two are rotationally connected. When the rotary part of the rotary cylinder 710 rotates, the third rotation shaft 720 is driven to rotate synchronously, and then the valve core 200 is driven to rotate between the first position and the second position.
