| titleOfInvention | Composite sand setting nozzle |
| abstract | The utility model discloses a composite sand setting nozzle, which comprises a rubber composite sand setting nozzle outer sleeve in a cylindrical structure, wherein a blanking through hole is arranged in the rubber composite sand setting nozzle outer sleeve along the axis direction, the blanking through hole is in a reducing structure, the inner diameter of the lower end of the blanking through hole is smaller than that of the upper end, the lower end of the blanking through hole is embedded into a silicon carbide wear-resisting ring, and the upper end edge of the silicon carbide wear-resisting ring is connected with the blanking through hole; the silicon carbide wear-resistant ring is of a straight cylindrical structure, and the height of the silicon carbide wear-resistant ring is smaller than that of the blanking through hole; the silicon carbide wear-resistant ring is sleeved on the lower part of the inner wall of the outer sleeve of the rubber composite sand setting nozzle in an interference fit manner; the upper part of the rubber composite sand setting nozzle jacket is integrally formed with a connecting ring, the blanking through holes are communicated with the connecting ring, and a plurality of connecting holes are uniformly formed in the connecting ring. The utility model discloses simple structure, it is with low costs to make, and it has combined the advantage that the compound sand setting of rubber is chewed and the compound sand setting of carborundum is chewed, has applied the shock resistance of rubber, the high wear resistance of carborundum. |
