[0002] Three-way feed valves are ideal devices for controlling the rapid reversal of materials in material conveying systems, and are widely used in the conveying of solid particles and powders in industries such as building materials, metallurgy, mining, light industry, and grain. Currently, traditional three-way feed valves suffer from problems such as complex structure, inflexible adjustment, and susceptibility to material jamming. Therefore, there is an urgent need to research a new type of three-way feed valve to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a three-way feed valve to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a three-way material distribution valve, including a valve body, an inlet channel opened at the upper part of the valve body, and outlet channels communicating with the inlet channel respectively opened on both sides of the lower part of the valve body, and a valve rotatably connected in each outlet channel; it also includes a drive transmission device, which operates to drive the valve to rotate in the outlet channel to close or open the outlet channel.

[0005] Preferably, the drive transmission device includes a drive cylinder, an L-shaped swing arm hinged to the drive cylinder, a rotating shaft rotatably connected in the discharge channel, a valve fixedly connected to the rotating shaft, and the other end of the L-shaped swing arm sleeved on the rotating shaft.

[0006] Preferably, when the valve is closed to the discharge channel, the end of the valve away from the rotating shaft abuts against the inner wall of the discharge channel.

[0007] Preferably, the rotating shaft is connected to the valve body via a bearing with a square seat.

[0008] Preferably, the two discharge channels are arranged symmetrically.

[0009] Preferably, the valve and the rotating shaft are detachably connected via a connecting device.

[0010] Preferably, the connecting device includes a plug fixedly connected to one side of the valve, a socket on a mounting plate of the rotating shaft, a sliding block slidably connected to the inner cavity of the plug, a first spring provided between the bottom of the sliding block and the inner wall of the plug, a locking block fixedly connected to the top of the sliding block, the locking block being slidable into the inner cavity of the plug, and the side wall of the locking block being arc-shaped, a locking hole being provided at the top of the socket, the plug being able to be inserted into the inner cavity of the socket, and the locking block being able to extend into the inner cavity of the locking hole.

[0011] Preferably, a connecting plate is slidably connected to the inner cavity of the card hole, and a second spring is fixedly connected between the bottom of the connecting plate and the inner wall of the card hole. A square block is fixedly connected to the bottom of the connecting plate, and the square block is slidably connected to the card hole. A threaded hole is opened on the side wall of the mounting plate above the card hole, and a bolt is threaded into the threaded hole. The bolt can extend into the inner cavity of the card hole.

[0012] Preferably, the number of the inserts is two sets, and the two sets of inserts are symmetrically arranged about the center line of the valve.

[0013] Preferably, each of the sockets is provided in two sets, and the two sets of sockets are symmetrically arranged about the center line of the mounting plate.

[0014] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The present invention provides a three-way material distribution valve, which is composed of a feeding channel, two discharge channels, a valve, and a drive transmission device. The operation of the drive cylinder drives the swing of the L-shaped swing arm connected to it, thereby driving the rotation of the rotating shaft, so that the valve connected to the rotating shaft can rotate, thereby closing or opening the discharge channel. The structure is simple and convenient for flexible adjustment of material distribution.

[0015] 2. This utility model provides a three-way feed valve, in which the valve and the rotating shaft are detachably connected via a connecting device. The connecting device consists of a plug, a socket, a sliding block, and a locking block. The plug is inserted into the socket cavity, and the locking block extends into the socket cavity under the elastic force of a first spring, completing the engagement and thus installing the valve. Then, bolts are used to press the connecting plate and the square block downwards within the socket cavity until the square block contacts the locking block, which then pushes the locking block into the socket cavity until it slides into the socket cavity. At this point, the plug can be pulled out of the socket cavity, completing the disassembly. The operation is convenient and simple. When the valve wears down to a certain value during prolonged use, only the valve needs to be replaced, without replacing the rotating shaft and valve together. This greatly reduces material waste and costs, while also improving installation efficiency. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example like Figures 1 to 5 As shown, a three-way feed valve includes a valve body 9. The upper part of the valve body 9 has a feed channel 5, and the lower two sides of the valve body 9 each have a discharge channel 4 communicating with the feed channel 5. The two discharge channels 4 are symmetrically arranged, and a valve 1 is rotatably connected within each discharge channel 4. The valve body also includes a drive transmission device that operates to drive the valve 1 to rotate within the discharge channel 4, thereby closing or opening the discharge channel 4. When the valve 1 is closed with the discharge channel 4, the end of the valve 1 away from the rotating shaft 8 abuts against the inner wall of the discharge channel 4. The drive transmission device includes a drive cylinder 6 and an L-shaped swing arm 7 hinged to the drive cylinder 6. A rotating shaft 8 is rotatably connected within the discharge channel 4, and the valve 1 is fixedly connected to the rotating shaft 8. The other end of the L-shaped swing arm 7 is sleeved on the rotating shaft 8. The rotating shaft 8 is connected to the valve body 9 via a square bearing 10. This structure employs a three-way material distribution valve, which consists of a feed channel 5, two discharge channels 4, a valve 1, and a drive transmission device. The drive transmission device operates to rotate the valve 1 within the discharge channel 4, thereby closing or opening the discharge channel 4, thus facilitating flexible adjustment of material distribution.

[0023] like Figure 6 , Figure 7 and Figure 8As shown, valve 1 and rotating shaft 8 are detachably connected via a connecting device. The connecting device includes a plug 102 fixedly connected to one side of valve 1 and a socket 103 opened on the mounting plate 81 of rotating shaft 8. A sliding block 2 is slidably connected to the inner cavity of plug 102. A first spring 201 is provided between the bottom of sliding block 2 and the inner wall of plug 102. A locking block 202 is fixedly connected to the top of sliding block 2. The locking block 202 can slide into the inner cavity of plug 102, and the side wall of locking block 202 is arc-shaped. A locking hole 203 is opened at the top of socket 103, and plug 102 can be inserted into the inner cavity of socket 103. The locking block 202 can extend into the inner cavity of locking hole 203. There are two sets of plugs 102, and the two sets of plugs 102 are symmetrically arranged about the center line of valve 1. There are two sets of sockets 103, and the two sets of sockets 103 are symmetrically arranged about the center line of mounting plate 81.

[0024] like Figure 6 , Figure 8 and Figure 9 As shown, a connecting plate 3 is slidably connected to the inner cavity of the card hole 203. A second spring 301 is fixedly connected between the bottom of the connecting plate 3 and the inner wall of the card hole 203. A square block 302 is fixedly connected to the bottom of the connecting plate 3, and the square block 302 is slidably connected to the card hole 203. A threaded hole 303 is opened on the side wall of the mounting plate 81 located above the card hole 203. A bolt 304 is threadedly connected to the threaded hole 303, and the bolt 304 can extend into the inner cavity of the card hole 203.

[0025] In practical use: The operation of the drive cylinder 6 causes the L-shaped swing arm 7 connected to it to swing, which in turn causes the rotating shaft 8 to rotate, so that the valve 1 connected to the rotating shaft 8 can rotate, thereby closing or opening the discharge channel 4, thus facilitating flexible adjustment of material distribution.

[0026] When valve 11 needs to be installed with rotating shaft 8, first insert block 102 into the inner cavity of insertion hole 103. At this time, because the side wall of locking block 202 is arc-shaped, when locking block 202 contacts the inner wall of insertion block 102, locking block 202 is squeezed and slides into the inner cavity of insertion block 102, that is, locking block 202 and sliding block 22 As the first spring 201 is compressed and generates a rebound force, the first spring 201 moves into the inner cavity of the insert block 102 until the locking block 202 slides into the inner cavity of the insert block 102. At this time, the insert block 102 can be fully inserted into the inner cavity of the socket 103. When the locking block 202 slides to the bottom of the socket 203, under the action of the rebound force of the first spring 201, the sliding block 22 and the locking block 202 will slide to the outside of the insert block 102. The locking block 202 slides into the inner cavity of the socket 203, completing the locking of the locking block 202 and the socket 203, and the insertion block 102 and the socket 103 respectively. Thus, the valve 1 is installed on the mounting plate 81 of the rotating shaft 8.

[0027] When valve 1 needs to be disassembled, remove bolt 304, align bolt 304 with threaded hole 303 and rotate it. At this time, bolt 304 moves into the inner cavity of threaded hole 303 until bolt 304 enters the inner cavity of retaining hole 203. Bolt 304 then contacts connecting plate 33. Continue to rotate bolt 304, bolt 304 will squeeze connecting plate 33 and drive square block 302 to move downward. At this time, second spring 301 is squeezed. Then square block 302 contacts retaining block 202 and drives retaining block 202 to slide into inner cavity of insert block 102 until retaining block 202 is fully inserted into inner cavity of insert block 102. At this time, wall panel 1 can be disassembled. After disassembly, remove bolt 304 from inner cavity of threaded hole 303. Then, under the rebound force of second spring 301, connecting plate 33 and square block 302 return to their original positions for the next installation.

[0028] 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.
