[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0022] See also Figures 1 to 4 In this embodiment, an anti-wear slag discharge valve is provided, including a valve body 1, a valve plate 5 is slidably connected to the inside of the valve body 1, a wear-resistant block 53 is installed on the valve plate 5, and the wear-resistant block 53 consists of two identical parts, a valve plate 2 6 is slidably connected to the inside of the valve body 1 on one side of the valve plate 1 5, a fixing frame 2 is fixedly connected above the valve body 1, the fixing frame 2 is located between the valve plate 1 5 and the valve plate 2 6, and a lifting mechanism for lifting and lowering the valve plate 1 5 and the valve plate 2 6 is installed on the fixing frame 2.

[0023] When in use, the valve plate 1 5 and the valve plate 2 6 can be driven to move up and down respectively through the lifting mechanism. In daily use, the valve plate 1 5 is moved up and down to achieve the purpose of opening and closing the valve body 1. The wear resistance of the valve plate 1 5 is improved by the wear-resistant block 53, thereby improving the service life of the valve plate 1 5. When the valve plate 1 5 needs to be replaced, the valve body 1 is closed by lowering the valve plate 2 6, and then the valve plate 1 5 is raised, so that the height of the valve plate 1 5 only needs to leak out half the height of the wear-resistant block 53, and the entire wear-resistant block 53 can be taken out for replacement. At the same time, according to the wear condition of the wear-resistant block 53, half of the wear-resistant block can be replaced to achieve the purpose of saving costs.

[0024] In further embodiments, see Figure 2 The two sides of the valve plate 1 5 and the valve plate 2 6 have the same contour as the inner contour of the valve body 1, and the two sides of the valve plate 1 5 and the valve plate 2 6 fit the inner contour of the valve body 1. The inner contour of the valve body 1 is a plurality of stepped structures, and after the valve plate 1 5 and the valve plate 2 6 are lowered, the plurality of channels with different diameters in the inner contour of the valve body 1 can be blocked, thereby closing the valve body 1.

[0025] In further embodiments, see Figure 4The valve plate 1 5 includes a plate body 51, a mounting groove 52 is provided at the lower end of the plate body 51, a wear-resistant block 53 is located inside the mounting groove 52, a disassembly opening 54 is provided near the upper end of the plate body 51, and the disassembly opening 54 can completely accommodate half of the wear-resistant block 53, and a pressing plate 55 is provided on the plate body 51 above the disassembly opening 54. The mounting groove 52 matches the outer contour of the entire wear-resistant block 53 so that the entire wear-resistant block 53 can be accommodated. The lower half of the wear-resistant block 53 is provided with a protruding edge so that it cannot be laterally moved away from the mounting groove 52 and can only be laterally moved out through the disassembly opening 54. When in use, the disassembly opening 54 is blocked by the pressing plate 55 to prevent half of the wear-resistant block 53 from moving out. At the same time, the pressing plate 55 remains in contact with the inside of the valve body 1 during use so that it cannot move laterally, thereby limiting the wear-resistant block 53. When half of the wear-resistant block 53 is a semi-cylindrical body, when it leaks out of the disassembly opening 54, the upper wear-resistant block 53 is taken out horizontally, and then the lower wear-resistant block 53 is rotated so that the lower wear-resistant block 53 is rotated to the upper disassembly opening 54, so as to take out the lower wear-resistant block 53. When half of the wear-resistant block 53 is located in a rectangular body, when the upper wear-resistant block 53 is taken out horizontally, the lower wear-resistant block 53 is moved upward and taken out horizontally.

[0026] In a further embodiment, a plurality of grooves are provided on one side of the wear-resistant block 53, the grooves are close to the valve plate 2 6, and a wear-resistant coating is provided on the outer side of the grooves. The grooves reduce the area of ​​direct collision between the wear-resistant block 53 and particles, reduce wear, and the wear-resistant ability of the wear-resistant block 53 is further enhanced by the wear-resistant coating.

[0027] In further embodiments, see Figure 1 The valve body 1 has connecting flanges at both ends, and a plurality of connecting holes are provided on the connecting flanges. The connecting flanges are connected to the pipeline, and bolts or other fasteners are inserted through the connecting holes to fasten the valve body 1 to avoid separation from the pipeline.

[0028] In further embodiments, see Figure 3 The lifting mechanism includes a hand wheel 3, which is rotatably connected to the fixing frame 2. A threaded rod 4 is threadedly connected to the inside of the hand wheel 3, and a connecting block is connected to the bottom of the threaded rod 4. A connecting rod 41 is inserted into the inside of the connecting block. Through holes are provided above the valve plate 1 5 and the valve plate 2 6, and the connecting rod 41 can be inserted into the valve plate 1 5 and the valve plate 2 6. The threaded rod 4 can be driven to rotate by rotating the hand wheel 3, and the threaded rod 4 is lifted after rotating. The connecting rod 41 below is inserted into the through hole of the valve plate 1 5 or the valve plate 2 6, thereby driving the valve plate 1 5 or the valve plate 2 6 to rise and fall, thereby realizing the opening and closing functions of the valve plate 1 5 and the valve plate 2 6, and the disassembly and replacement functions of the valve plate 1 5.

[0029] In further embodiments, see Figure 2The valve plate 2 6 is provided with slots on both sides, and a clip 61 is connected inside the slots. The clip 61 is made of elastic material. When leaking out of the valve body 1 through the clip 61, it can pop out. The clip 61 supports the valve plate 2 6 to prevent the valve plate 2 6 from falling. When the valve plate 2 6 is driven to move downward, the clip 61 can be pressed to be stored inside the slot, so that it can extend into the valve body 1.
