Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an anti-erosion slurry valve. Background Technology

[0002] In alumina conditions, alkaline mud and particulate media can easily cause scaling inside valves. The presence of alumina particles in the medium causes erosion and wear on the valve's sealing surface, eventually leading to the valve failing to close properly and becoming unusable. This makes it difficult to reopen the valve, affecting the entire production process. Scale formation is also a common occurrence in alumina conditions.

[0003] Utility model patent CN203926822U discloses an erosion-resistant slurry valve. This slurry valve includes a left valve body, a right valve body, a valve seat, and a valve disc. The left and right valve bodies are assembled via a connector. A valve seat is located on the inner side between the left and right valve bodies, and the valve seat has an annular boss. The valve disc has a first cylinder and a second cylinder. The first cylinder is positioned on the valve disc closer to the annular boss than the second cylinder, and its diameter is smaller than that of the second cylinder. During the opening and closing of the slurry valve, the annular boss, the first cylinder, and the second cylinder form an erosion-resistant channel with an angular cross-section. When the valve is opened and closed, the erosion of the valve body by the medium is most severe. The valve seat and valve disc cooperate to form an angular erosion-resistant channel, which can change the flow direction of the high-pressure medium, preventing the erosion effect of the high-pressure medium flow from directly impacting the valve seat and the inner wall of the valve body, thus protecting the valve's inner wall and achieving excellent erosion resistance.

[0004] The aforementioned device forms an erosion-resistant channel with an angular cross-section through the cooperation of the valve seat and valve disc. It does not directly act on the inner wall of the valve body. However, due to the gravity of the medium itself, when the valve is opened and closed, most of the medium is in the lower half of the medium flow. The wear caused by the erosion of the lower half of the valve is much more severe than that of the upper half. Therefore, the upper half of the valve is still well sealed, but the lower half has already leaked, which greatly reduces the service life of the slurry valve. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An embodiment of this utility model provides an anti-erosion slurry valve, comprising an inlet pipe 2, a connector 8 at the end of the inlet pipe 2, a valve seat 7 on the outer wall of the inlet pipe 2, an outlet pipe 3 fixedly mounted on the side wall of the connector 8, a sealing pipe 9 fixedly mounted on the top of the connector 8, a sealing ring 11 fixedly mounted on the outer wall of the sealing pipe 9, a sleeve 10 fixedly mounted on the outer wall of the sealing ring 11, a rotating mechanism 5 mounted on the top of the sleeve 10, a mounting bracket 1 mounted above the rotating mechanism 5, a cylinder 4 fixedly mounted at the bottom of the mounting bracket 1, the output shaft end of the cylinder 4 being rotatably connected to the rotating mechanism 5, a sealing ring 12 fixedly mounted inside the inlet pipe 2, a sealing rod fixedly mounted at the bottom of the rotating mechanism 5, a valve 13 fixedly mounted at the end of the sealing rod, a sealing plate 14 fixedly mounted inside the sealing pipe 9, and a scraping mechanism 6 slidably mounted on the inner side wall of the sealing pipe 9. First, the cylinder 4 output shaft retracts, driving the rotating mechanism 5 to move, which in turn drives the sealing rod and valve 13 to move. The valve 13 moves synchronously, driving the scraping mechanism 6 to move. The valve 13 moves to open the seal, allowing the medium to flow from the inlet pipe 2 to the outlet pipe 3.

[0023] Specifically, the rotating mechanism 5 includes a rotating column 51, two vertical grooves 52, two spiral grooves 53, a round-headed column 54, a return spring 55, a disc 56, a connecting column 57, and a plug-in column 58. The connecting column 57 is fixedly installed at the bottom of the mounting bracket 1, the disc 56 is fixedly installed at the end of the output shaft of the cylinder 4, the rotating column 51 is rotatably installed at the end of the output shaft of the cylinder 4, and the disc 56 rotates inside the rotating column 51. The two vertical grooves 52 are installed on the side wall of the rotating column 51, the two spiral grooves 53 are installed on the side wall of the rotating column 51, and the two ends of the two vertical grooves 52 are respectively connected to the two spiral grooves 53. The plug-in column 58 is fixedly installed at the end of the connecting column 57, the round-headed column 54 is movably plugged into the end of the plug-in column 58, and the return spring 55 is installed between the round-headed column 54 and the connecting column 57. The cylinder 4 output shaft retracts, driving the rotating column 51 to move. As the rotating column 51 moves, it rotates 180 degrees due to the limiting sliding action of the round head column 54 within the spiral groove 53, simultaneously driving the sealing rod and valve 13 to rotate synchronously. This allows the lower half of the valve 13, which is frequently subjected to erosion and wear, to be switched with the upper half, avoiding continuous erosion of one position, greatly increasing the erosion resistance of the valve 13 and extending its service life.

[0024] Specifically, the two vertical slots 52 are set at an angle.

[0025] Specifically, the scraping mechanism 6 includes two scrapers 61, a T-shaped plate 62, a rotating shaft 63, two sliding grooves 64, two rotating plates 65, two vertical plates 66, and a torsion spring 67. The two sliding grooves 64 are disposed on the inner side wall of the sealing tube 9. The T-shaped plate 62 is slidably disposed inside the sliding groove 64. The rotating shaft 63 is rotatably disposed on the side wall of the T-shaped plate 62. The torsion spring 67 is sleeved on the outer wall of the rotating shaft 63. The two rotating plates 65 are respectively fixedly disposed at both ends of the rotating shaft 63. The two scrapers 61 are fixedly disposed at one end of the two rotating plates 65. The two vertical plates 66 are respectively fixedly disposed at the other end of the two rotating plates 65. The valve 13 moves to contact the rotating plate 65, causing the rotating plate 65 to rotate. The rotation of the rotating plate 65 drives the scraper 61 to adhere to the arc-shaped surface of the valve 13 near the water inlet pipe 2. The valve 13 continues to move to contact the vertical plate 66, thereby driving the T-shaped plate 62 and the valve 13 to move synchronously. When the valve 13 resets, the rotating plate 65 automatically resets under the action of the torsion spring 67. This achieves the automatic cleaning of the scale on the arc-shaped surface of the valve 13 as the valve 13 rotates, ensuring the smoothness of the valve 13 surface and avoiding the deterioration of sealing caused by scale. It requires no manual operation, has a high degree of automation, and is convenient and quick.

[0026] Specifically, the top of the T-shaped plate 62 abuts against the inner wall of the sealing tube 9, so that when the valve 13 moves toward the sealing plate 14, it can first drive the rotating plate 65 to rotate, and then abut against the vertical plate 66 to drive the T-shaped plate 62 to slide.

[0027] Specifically, the scraper 61 is adapted to the surface shape of the valve 13; thus, the scraper 61 can fit against the surface of the valve 13, ensuring its scraping effect.

[0028] Working principle: First, the output shaft of cylinder 4 retracts, driving the rotating column 51 to move. As the rotating column 51 moves, under the limiting sliding action of the round head column 54 located in the spiral groove 53, the rotating column 51 rotates 180 degrees, synchronously driving the sealing rod and valve 13 to rotate synchronously. This synchronously drives the sealing rod and valve 13 to move, and the valve 13 moves to abut against the rotating plate 65, causing the rotating plate 65 to rotate. The rotation of the rotating plate 65 drives the scraper 61 to adhere to the arc-shaped surface of the valve 13 near the water inlet pipe 2. The valve 13 continues to move to abut against the vertical plate 66, thereby driving the T-shaped plate 62 and valve 13 to move synchronously. The movement of valve 13 opens the seal, allowing the medium to flow from the water inlet pipe 2 to the water outlet pipe 3.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
