Description

Technical Field

[0001] This application relates to the field of valve body structure technology, and in particular to a feed swing valve with guiding function. Background Technology

[0002] To facilitate the control of solid material supply, a feed swing valve mechanism is usually set up. Existing swing valves have one input end and one output end. One swing valve can only be used to control the supply of one feed pipe. Multiple feed pipes require a corresponding number of swing valves. However, the space required for swing valves is relatively large, so a large number of swing valves will make the feed pipeline system very bloated. Summary of the Invention

[0003] The purpose of this application is to provide a feed swing valve with a guiding function that can control multiple feed pipelines.

[0004] To achieve the above objectives, this application provides a feed swing valve with a guiding function: it includes a first housing and a second housing. The first housing has a feed pipe, and the second housing has a first discharge port and a second discharge port. A valve core is disposed between the first housing and the second housing. The valve core is rotatably connected to both the first housing and the second housing. The main body of the valve core is a baffle plate. The side of the baffle plate has a swing arm. The surface of the swing arm has a sliding shaft. An extension arm is also fixedly connected to the side of the first housing and the second housing. A traction device is movably connected between the extension arm and the sliding shaft to drive the valve core to achieve guiding control of different feed pipelines.

[0005] As a preferred embodiment, the first housing includes a first flat plate with a first shaft hole, and the second housing includes a second flat plate with a second shaft hole. The axes of the second shaft hole and the first shaft hole are collinear. The end of the swing arm away from the baffle plate has a main shaft, which is suitable for passing through both the first shaft hole and the second shaft hole to form a rotating pair, thereby ensuring the stability of the valve core within the housing.

[0006] As a preferred embodiment, the second plate is also provided with a groove through which the sliding shaft passes. The groove is adapted to limit the swing range of the valve core and prevent the baffle plate from sliding out of the housing.

[0007] As a preferred embodiment, the slide groove extends along an arc, with the center of the arc located on the axis of the main shaft. The slide shaft and the slide groove cooperate to form a sliding pair, thereby improving the smoothness of the valve core movement.

[0008] As a preferred embodiment, the edge of the second plate has a connecting strip, which is fixedly connected to the edge of the first plate, and the end of the feed pipe has a connecting disc for connecting to the feeding hole.

[0009] As a preferred embodiment, the traction device includes a cylinder and a telescopic rod that cooperate with each other. The end of the cylinder is rotatably connected to the extension arm, and the end of the telescopic rod is rotatably connected to the sliding shaft, ensuring that the traction device has sufficient deflection freedom when extending and retracting.

[0010] As a preferred embodiment, the end of the extension arm away from the housing has a fixed shaft, and the end of the cylinder has a first bushing. The end of the fixed shaft passes through the first bushing and is fixedly connected to a limit ring to prevent the traction device from disengaging from the constraint of the extension arm and to ensure stable transmission.

[0011] As a preferred embodiment, the end of the telescopic rod has a second bushing, and the sliding shaft cooperates with the second bushing to form a rotating pair, ensuring the degree of freedom at both ends of the traction device.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting two discharge ports and connecting them to two feed pipes respectively, one swing valve can control the operation of more feed pipes, reducing the number of swing valves used and increasing the utilization rate of a single swing valve, thereby simplifying the structure of the feed pipe system.

[0014] (2) The design is simple in structure, easy to control, has high working stability and low failure rate, which makes the use and maintenance costs relatively low. Attached Figure Description

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8The feed swing valve with guiding function shown includes a first housing 1 and a second housing 2. The first housing 1 includes a first plate 101, and the second housing 2 includes a second plate 201. The first plate 101 and the second plate 201 are parallel. The edge of the second plate 201 has a connecting strip 206 with uniform width. The connecting strip 206 is fixedly connected to the edge of the first plate 101 to limit the position between the first housing 1 and the second housing 2. The first housing 1 has a feed pipe 103. The end of the feed pipe 103 away from the first plate 101 has a connecting plate 104 for fixed connection with the feeding funnel. The second housing 2 has a first discharge port 203 and a second discharge port 204. The horizontal projections of the first discharge port 203 and the second discharge port 204 are completely located inside the feed pipe 103.

[0029] A valve core 5 is provided between the first housing 1 and the second housing 2. The valve core 5 is rotatably connected to both the first housing 1 and the second housing 2. Specifically, the first plate 101 has a first shaft hole 102, and the second plate 201 has a second shaft hole 202. The second shaft hole 202 and the first shaft hole 102 are collinear and their inner walls are aligned. The main body of the valve core 5 is a baffle plate 502. The baffle plate 502 is larger than the feed pipe 103. The side of the baffle plate 502 has a swing arm 501. The end of the swing arm 501 away from the baffle plate 502 has a main shaft 503, which is used to pass through the first shaft hole 102 and the second shaft hole 202 to form a rotating pair, restricting the degree of freedom of the swing arm 501 and improving the stability of the valve core 5's movement.

[0030] The surface of the swing arm 501 has a sliding shaft 504, the axis of which is parallel to the axis of the main shaft 503. The second plate 201 is also provided with a sliding groove 205. The sliding shaft 504 extends through the sliding groove 205 to the outside of the second housing 2. The sliding groove 205 is used to limit the swing range of the valve core 5 and prevent the baffle plate 502 from coming out between the first plate 101 and the second plate 201. The sliding groove 205 extends along an arc, and the center of the arc is located on the axis of the main shaft 503. Therefore, the sliding shaft 504 and the sliding groove 205 fit together to form a sliding pair, which further improves the stability of the swing of the valve core 5.

[0031] An extension arm 3 is fixedly connected to the side of the first housing 1 and the second housing 2. A traction device 4 is movably connected between the extension arm 3 and the sliding shaft 504. The traction device 4 is usually a cylinder or hydraulic cylinder structure. The specific structure includes a cylinder 401 and a telescopic rod 402 that cooperate with each other. The end of the cylinder 401 is rotatably connected to the extension arm 3, and the end of the telescopic rod 402 is rotatably connected to the sliding shaft 504. The end of the extension arm 3 away from the housing has a fixed shaft 301. The end of the cylinder 401 has a first bushing 403. The end of the fixed shaft 301 passes through the first bushing 403 and is fixedly connected to a limit ring 302 to prevent the traction device 4 from detaching from the extension arm 3. The end of the telescopic rod 402 has a second bushing 404. The sliding shaft 504 and the second bushing 404 cooperate to form a rotating pair to ensure that both ends can make adaptive angle deflections when the traction device 4 moves telescopically.

[0032] Working principle: The feed pipe 103 is usually installed facing upwards and connected to the feeding hopper. The first discharge port 203 and the second discharge port 204 are respectively connected to two output pipes. This feed swing valve has four working states. The first state is that the baffle plate 502 completely blocks the end of the feed pipe 103, and at the same time completely blocks the first discharge port 203 and the second discharge port 204. The swing valve is in the closed state, and the material conveying stops. The second state is that the baffle plate 502 does not block the connection between the first discharge port 203, the second discharge port 204 and the feed pipe 103. The feed pipe 103 feeds the first discharge port 203 and the second discharge port 204. 4. Material conveying: Both output pipes will supply material downwards simultaneously; In the third case, the baffle plate 502 completely blocks the first discharge port 203, but the feed pipe 103 is connected to the second discharge port 204, so only the output pipe connected to the second discharge port 204 will supply material downwards; In the fourth case, the baffle plate 502 completely blocks the second discharge port 204, but the feed pipe 103 is connected to the first discharge port 203, so only the output pipe connected to the first discharge port 203 will supply material downwards. In summary, this feed swing valve has multiple material discharge methods, which can be flexibly adjusted according to actual production needs.
