Technical Field

[0001] This utility model belongs to the field of material diversion technology, and more specifically, it relates to a powder material diversion valve. Background Technology

[0002] The powder and granular material diversion valve plays a crucial role in the powder and granular material conveying system, as it is responsible for accurately distributing the material to different conveying paths as needed.

[0003] Because powdery materials typically have small particle size and high flowability, if leakage occurs between the valve plate and the valve body, the material will enter the wrong conveying path, leading to chaos in the production process and a decline in product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a powder material diversion valve, which aims to solve the problem of material leakage between the valve plate and the valve body, which causes the material to enter the wrong conveying path, resulting in production process chaos and product quality decline.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a powder material diversion valve, including an upper valve body and a three-way material distribution pipe;

[0006] The upper valve body has a feed inlet at its upper end and a flow divider is provided at the middle of the lower end of the upper valve body. The flow divider is used to divide the lower port of the upper valve body into two discharge ports. A valve plate is provided in the inner cavity of the upper valve body. A drive mechanism is provided on the outer wall of the upper valve body to drive the valve plate to swing left and right. The two sides of the valve plate form guide surfaces for guiding materials into either of the discharge ports.

[0007] The upper end of the three-way material distribution pipe is provided with a material receiving port, and the lower end of the three-way material distribution pipe is provided with two material distribution pipes that connect to the material receiving port. The upper ports of the two material distribution pipes correspond one-to-one with the two material discharge ports.

[0008] The lower end of the valve plate is provided with an arc-shaped surface, which is in contact with the upper end of the flow divider plate to close the gap between the lower end of the valve plate and the upper end of the flow divider plate.

[0009] In one possible implementation, the width of the longitudinal section of the valve plate decreases from top to bottom.

[0010] In one possible implementation, the lower end of the valve plate is provided with two limiting blocks, which are located at the two ends of the arc-shaped surface, respectively.

[0011] In one possible implementation, the outer side of the limiting block conforms to the guide surface on the same side, and the inner side of the limiting block slopes outward from top to bottom.

[0012] In one possible implementation, the central axis of the arcuate surface is collinear with the output axis of the drive mechanism.

[0013] In one possible implementation, the longitudinal section of the diversion baffle is an isosceles triangle, and the width decreases from top to bottom.

[0014] In one possible implementation, the inner contour of the receiving port is larger than the inner contour of the lower port of the upper valve body.

[0015] In one possible implementation, a sealing gasket is provided between the upper valve body and the three-way feed pipe.

[0016] In one possible implementation, the drive mechanism is a servo motor.

[0017] In one possible implementation, inwardly extending eaves are provided on both sides of the feed inlet, the eaves being used to cover the gap between the upper end of the valve plate and the inner wall of the upper valve body.

[0018] The beneficial effects of the powder / granular material diversion valve provided by this utility model are as follows: Compared with the prior art, the upper valve body is provided with a feed inlet at the upper end for receiving powder / granular materials. A diversion baffle is provided in the middle of the lower end of the upper valve body, dividing the lower port of the upper valve body into two discharge ports. Simultaneously, the valve plate is located within the inner cavity of the upper valve body, with guide surfaces on both sides. When material flows in, the guide surfaces guide the material smoothly into either discharge port. The lower end of the valve plate is designed as an arc-shaped surface, which fits snugly against the upper end of the diversion baffle. Regardless of how the valve plate swings left and right under the action of the drive mechanism, the arc-shaped surface always fits against the upper end of the diversion baffle, sealing any gaps that may occur between them, preventing material leakage, and effectively preventing material from entering the wrong conveying path. The powder / granular material diversion valve provided by this utility model eliminates chaotic situations such as equipment shutdowns for cleaning and material rework caused by material leakage, allowing the production line to operate continuously and smoothly, effectively ensuring production efficiency.

[0026] Please see Figure 1 and Figure 2 The present invention provides a powder material diversion valve. The powder material diversion valve includes an upper valve body 2 and a three-way diversion pipe 5. The upper valve body 2 has an inlet at its upper end and a diversion baffle 4 at the lower middle of its lower end. The diversion baffle 4 divides the lower end of the upper valve body 2 into two discharge ports. A valve plate 3 is provided inside the upper valve body 2, and a driving mechanism 1 is provided on the outer wall of the upper valve body 2 to drive the valve plate 3 to swing left and right. Guiding surfaces 7 are formed on both sides of the valve plate 3 to guide material into either discharge port. The upper end of the three-way diversion pipe 5 has a receiving port 10, and the lower end of the three-way diversion pipe 5 has two diversion pipes connecting to the receiving port 10. The upper ends of the two diversion pipes correspond one-to-one with the two discharge ports. The lower end of the valve plate 3 has an arc-shaped surface 9, which fits against the upper end of the diversion baffle 4 to close the gap between the lower end of the valve plate 3 and the upper end of the diversion baffle 4.

[0027] This utility model provides a powder / granular material diversion valve. Compared with the prior art, the upper valve body 2 has a feed inlet at its upper end for receiving powder / granular materials. A diversion baffle 4 is located in the middle of the lower end of the upper valve body 2, dividing the lower end of the upper valve body 2 into two discharge ports. Simultaneously, a valve plate 3 is located within the inner cavity of the upper valve body 2, with guide surfaces 7 on both sides. When material flows in, the guide surfaces 7 guide the material smoothly into either discharge port. The lower end of the valve plate 3 is designed as an arc-shaped surface 9, which fits snugly against the upper end of the diversion baffle 4. Regardless of how the valve plate 3 swings left and right under the action of the drive mechanism 1, the arc-shaped surface 9 always fits against the upper end of the diversion baffle 4, sealing any gaps that may occur between them, preventing material leakage, and effectively preventing material from entering the wrong conveying path. This powder / granular material diversion valve eliminates chaotic situations such as equipment shutdowns for cleaning and material rework caused by material leakage, allowing the production line to operate continuously and smoothly, effectively ensuring production efficiency.

[0028] Please see Figure 2 The width of the longitudinal section of valve plate 3 decreases from top to bottom, and the guide surface 7 is located on both sides of valve plate 3, forming a discharge port to guide the material into the corresponding side. Especially when dealing with complex working conditions where multiple materials are mixed or where frequent switching of diversion paths is required, it greatly reduces the possibility of material cross-flow and mixing, ensuring that each batch of material can accurately enter the predetermined conveying path, providing a reliable material distribution guarantee for subsequent production processes.

[0029] Please see Figure 2 Two limiting blocks 8 are provided at the lower end of the valve plate 3, located at both ends of the arc-shaped surface 9. These limiting blocks 8 restrict the left and right swing angle of the valve plate 3, preventing the upper end of the valve plate 3 from severely colliding with the inner wall of the valve body 2. When the valve plate 3 swings to its maximum angle, the limiting blocks 8 adhere to one side of the upper end of the flow divider 4, forming a secondary sealing structure, further reducing material leakage between the arc-shaped surface 9 and the flow divider 4.

[0030] Preferably, the outer surface of the limiting block 8 conforms to the shape of the guide surface 7 on the same side, and the inner surface of the limiting block 8 slopes outward from top to bottom. The conformity of the outer surface of the limiting block 8 to the guide surface 7 on the same side allows it to fit tightly against the valve plate 3, seamlessly connecting along the trajectory of the material guided by the valve plate 3. When the material flows towards the corresponding discharge port under the action of the guide surfaces 7 on both sides of the valve plate 3, the limiting block 8 ensures a continuous and stable flow path, further enhancing the accuracy of material diversion. Even under conditions of frequent opening and closing and high-speed operation of the valve plate 3, it effectively prevents cross-flow and turbulent flow caused by the material impacting abrupt structures, ensuring the orderly progress of the material distribution process. Furthermore, the inclination of the inner surface of the limiting block 8 from top to bottom allows it to fit against one side of the upper end face of the diversion baffle 4. This inclination increases the contact area between the limiting block 8 and the diversion baffle 4, resulting in a better sealing effect. When the equipment is subjected to vibration or other external interference during operation, this robust sealing structure can effectively prevent the limit block 8 and the diversion baffle 4 from becoming loose or displaced, thus avoiding material leakage.

[0031] Specifically, the central axis of the arc-shaped surface 9 is aligned with the output axis of the drive mechanism 1, ensuring that the arc-shaped surface 9 remains tightly fitted to the upper end of the flow divider 4 when the valve plate 3 swings left and right under the drive mechanism 1. Furthermore, a sealing layer can be provided at the contact point between the valve plate 3 and the flow divider 4. This sealing layer is made of rubber, possessing good flexibility and sealing performance.

[0032] The diversion baffle 4 has an isosceles triangle cross-section with its width decreasing from top to bottom, forming an arc-shaped tip at its top. This tip better fits the arc-shaped surface 9, creating a smaller gap between them and significantly reducing material leakage. Furthermore, the valve plate 3 has corresponding inclined guide surfaces on both sides, which also guide the material smoothly into the corresponding discharge port.

[0033] Preferably, the inner contour of the receiving port 10 is larger than the inner contour of the lower port of the upper valve body 2. The receiving port 10 forms a flared structure relative to the lower port of the upper valve body 2, so that the material can avoid the dead zone and fall directly into the three-way distribution pipe 5.

[0034] Specifically, a sealing gasket 6 is provided between the upper valve body 2 and the three-way distribution pipe 5. The upper valve body 2 and the three-way distribution pipe 5 are machined and finally assembled together. The sealing gasket 6 is a sealing ring structure, which is located between the connection surfaces of the upper valve body 2 and the three-way distribution pipe 5. It can ensure the sealing performance of the upper valve body 2 and the three-way distribution pipe 5 and reduce the risk of material leakage.

[0035] Specifically, drive mechanism 1 is a servo motor. The servo motor feeds back its actual position information to the control system via feedback devices (such as encoders and potentiometers). The control system compares and adjusts the set target value and the feedback value to achieve precise control of the motor, meeting the requirements of any set angle. The servo motor has good dynamic performance; by setting appropriate control parameters, it can buffer the swing position, avoiding large impacts and vibrations. The encoder and other feedback components equipped on the servo motor can monitor the motor's position and status in real time. When the swing is complete, it can send a corresponding signal to the control system, realizing the swing position feedback function.

[0036] Furthermore, inwardly extending eaves 11 are respectively provided on both sides of the feed inlet. The eaves 11 are used to cover the gap between the upper end of the valve plate 3 and the inner wall of the upper valve body 2. The feed inlet forms a flange structure in the circumference, and the two eaves 11 are integrally formed on the left and right sides of the inner opening of the flange structure. When the valve plate 3 swings to either extreme position, the upper end of the valve plate 3 is in contact with the inner wall of the upper valve body 2 or there is a small gap. At this time, the upper end of the valve plate 3 is located in the longitudinal projection area of ​​the eaves 11 on the same side. The eaves 11 cover the upper end of the valve plate 3 and the inner wall of the upper valve body 2, preventing the material entering through the feed inlet from falling into the wrong feed inlet through the gap between the upper end of the valve plate 3 and the inner wall of the upper valve body 2.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
