DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, what is described is only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See Figure 1-5 , a valve for filling a mining paste pipeline, comprising: a frame 1 and a valve body mechanism, wherein the valve body mechanism is arranged in the frame 1; The valve body mechanism includes two pipe heads 2 and a valve core assembly. The two pipe heads 2 are horizontally arranged and symmetrically fixedly sleeved in the frame 1. The valve core assembly is arranged between the two pipe heads 2. The valve core assembly includes a clamping ring 3, multiple groups of deflecting components and a guide cone 4. The clamping ring 3 is arranged horizontally, and its two ends are respectively sealed and rotatably sleeved on the ends of the two pipe heads 2 that are close to each other. The multiple groups of deflecting components are evenly arranged in an annular shape inside the clamping ring 3. The guide cone 4 is horizontally arranged in the middle of the clamping ring 3 and connected to the ends of the multiple groups of deflecting components that are close to each other. The deflection component includes a rotating shaft 5 and a baffle 6. The two ends of the rotating shaft 5 are rotatably sleeved in the retaining ring 3 and the guide cone 4 respectively. The baffle 6 is fixedly sleeved on the rotating shaft 5, and the two ends are in sealing and sliding contact with the inner surface of the retaining ring 3 and the outer surface of the guide cone 4 respectively. A driving mechanism is provided inside the clamping ring 3 for driving the multiple shafts 5 to rotate synchronously. The driving mechanism causes the multiple baffles 6 to tilt at a certain angle. Both pipe heads 2 are provided with cleaning mechanisms.

[0017] The driving mechanism includes multiple groups of rotating parts and two groups of limiting parts. The multiple groups of rotating parts correspond to multiple rotating shafts 5 respectively. The rotating parts include a slide rod 7, a first gear 8 and a first rack 9. The first gear 8 is fixedly sleeved on the end of the rotating shaft 5 located in the retaining ring 3. The slide rod 7 is horizontally slidably sleeved in the retaining ring 3. The first rack 9 is horizontally fixedly installed on the side of the slide rod 7 and is meshed with the first gear 8. The two groups of limiting parts are symmetrically arranged on the two side ends of the retaining ring 3.

[0018] The limiting component includes a slip ring 10 and a sleeve 11. The sleeve 11 is fixedly sleeved on the pipe head 2, and the slip ring 10 is slidably sleeved on the sleeve 11. The sides of the two slip rings 10 close to each other are respectively fixedly connected to the two ends of the multiple sliding rods 7. The sleeve 11 is provided with multiple pairs of first card grooves 12 and second card grooves 13, and two groups of card-embedding mechanisms are symmetrically arranged in the two slip rings 10.

[0019] The locking mechanism includes a pressure rod 14 and two groups of elastic components. The pressure rod 14 is arranged horizontally, and its two ends are respectively fixedly connected to the two slip rings 10 in a vertical sliding manner. The elastic components include a ball 15, a first spring 16, an insertion rod 17 and a second spring 18. A first slide groove 19 and a second slide groove 20 are vertically opened in the slip ring 10. The ball 15 is rolled and embedded in the first slide groove 19. The first spring 16 is vertically installed in the first slide groove 19, and the bottom end is in rolling contact with the ball 15. The top of the first spring 16 is fixedly connected to the top of the first slide groove 19. The insertion rod 17 is vertically slidably sleeved in the second slide groove 20. The second spring 18 is arranged vertically, and its two ends are respectively fixedly connected to the top of the second slide groove 20 and the top of the insertion rod 17. The pressure rod 14 and the insertion rod 17 are connected by a transmission component. The ball 15 is rolled and embedded in the first card groove 12, and the insertion rod 17 is slidably embedded in the second card groove 13.

[0020] The transmission components include a second gear 21, a second rack 22, a third rack 23 and a pin 24. The second gear 21 is rotatably mounted in the slip ring 10 via the pin 24. The second rack 22 and the third rack 23 are respectively vertically fixed on the side where the pressure rod 14 and the insertion rod 17 are close to each other, and are both meshed with the second gear 21.

[0021] When the device is used for paste filling, the pipe heads 2 on both sides are connected to the pipelines respectively.

[0022] When the device needs to be turned on, press the two pressure rods 14 at the same time. The two pressure rods 14 rotate the second gear 21 through the second rack 22. The second gear 21 drives the third rack 23 to move the insertion rod 17, compressing the second spring 18 and disengaging from the second slot 13. Then, while holding the two pressure rods 14, apply a thrust to one side to make the two slip rings 10 slide on the sleeve 11, and the ball 15 disengages from the first slot 12, while compressing the first spring 16.

[0023] When the two slip rings 10 move, they drive the slide rod 7 to move, and the slide rod 7 drives the first rack 9 to move. The movement of the first rack 9 causes the first gear 8 to drive the rotating shaft 5 to rotate, thereby causing the baffle 6 to deflect. Multiple baffles 6 deflect synchronously, and gaps appear between adjacent baffles 6, forming overflow holes 31. The valve body is connected as a whole, and the filling paste flows out through the overflow hole 31.

[0024] After the overflow hole 31 is opened to an appropriate size, the ball 15 and the rod 17 correspond to the first slot 12 and the second slot 13 respectively, the pressure rod 14 is released, and the first spring 16 and the second spring 18 return to their original length, so that the ball 15 and the rod 17 are respectively inserted into the corresponding first slot 12 and the second slot 13, thereby fixing the deflection angle of multiple baffles 6.

[0025] Since the baffle 6 is in an inclined state, multiple baffles 6 form an impeller structure. When the paste circulates, it impacts the impeller structure formed by the multiple baffles 6, thereby causing the clamping ring 3 to rotate, and then realizing the rotation of the valve core assembly, which can reduce the possibility of the paste adhering to the joints, thereby effectively avoiding blockage.

[0026] The cleaning mechanism includes multiple groups of scraping components and guide components. The scraping components include a scraper rod 25 and a block 26. The block 26 is fixedly installed inside the clamping ring 3. The scraper rod 25 is horizontally arranged in the pipe head 2, and the end is fixedly connected to the end of the block 26. The scraper rod 25 is in sliding contact with the inner wall of the pipe head 2.

[0027] The flow guide component includes a joint 27 and multiple mesh plates 28. A flow guide cavity 29 is opened inside the end of the tube head 2 away from the clamping ring 3. The joint 27 is vertically fixed and sleeved on the bottom side of the tube head 2, and is connected to the inside of the flow guide cavity 29. A plurality of through holes 30 are opened in the flow guide cavity 29 area on the inner wall of the tube head 2. Multiple mesh plates 28 are respectively fixedly installed in the multiple through holes 30. The mesh holes on the mesh plates 28 have a tiny aperture, and the paste cannot pass through. When the joint 27 is disconnected, it is in a normally closed state.

[0028] The clamping ring 3 rotates, and the multiple scraping rods 25 are driven to deflect through the clamping block 26 to scrape the inner wall of the tube head 2, which can effectively prevent the paste from adhering to the inner wall of the tube head 2, thereby ensuring the overall fluidity of the equipment.

[0029] After use, the two connectors 27 are connected to the external liquid discharge pump device and the liquid extraction pump device respectively. The liquid discharge pump device introduces cleaning liquid into the guide cavity 29 through the connector 27 to decompose the residual paste. The liquid extraction pump device can suck the waste liquid. At the same time, hold the two pressure rods 14 and move the two slip rings 10 left and right to change the diversion direction of multiple baffles 6. Synchronously twisting the retaining ring 3 forward and backward can make the cleaning liquid paste more fully decomposed, and the scraper rod 25 can scrape the inner wall of the pipe head 2 to facilitate cleaning inside the equipment.

[0030] When closing is required, the two pressure rods 14 are placed in the center position, and the multiple baffles 6 and the guide cone 4 block the inside of the clamping ring 3, thereby achieving shutoff.

[0031] This device realizes the opening and closing of the entire device through the sliding of the drive mechanism. Compared with the screw control, it is more convenient to operate.

[0032] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
