The rotary jet drilling tool series diverter is a device that delivers high-pressure slurry, compressed air and high-pressure water from high-pressure mud pump, air compressor and high-pressure clean water pump to the drill pipe respectively, and is installed on the top of the drill pipe or the top of the rotator. In terms of structure and strength, it can withstand a certain tension and the impact of vibration when lowering the drill pipe. This series of products adopts the most advanced sealing device in China at present, and the pressure resistance can reach 30MPa. It has good high-pressure sealing during the rotation of the drill pipe. It has the characteristics of convenient maintenance, simple disassembly and long service life. A check valve is set at the inlet of the air duct to avoid accidental damage to the air compressor.
