Rotary 12-nozzle jet-flow linear spray head

Abstract

The invention relates to a rotary 12-nozzle jet-flow linear spray head. The spray head comprises a spray head body, a rotating shaft, a shell, deep groove ball bearings, an angular contact ball bearing, a magnetic assembly, a high-pressure sealing head, a hollow sealing locking bolt, a sealing rod, a water inlet connector and a transition sealing piece. The spray head body is in threaded connection with one end of the rotating shaft, the rotating shaft is sleeved with the shell, one deep groove ball bearing, the angular contact ball bearing and the magnetic assembly are sequentially sleeved with the shell, and the other side of the magnetic assembly is sleeved with the other deep groove ball bearing; and the other end of the rotating shaft is in threaded connection with the high-pressure sealing head and the hollow sealing locking bolt, the sealing rod is sleeved with a center hole of the high-pressure sealing head and a center hole of the hollow sealing locking bolt, and the other end of the shell is in threaded connection with one end of the water inlet connector. The other end of the water inlet connector is in threaded connection with the transition sealing piece. The spray head has the beneficial effects of a compact structure, high-speed injection and prolonged service life.

Description

technical field [0001] The invention belongs to the technical field of high-pressure nozzles, and relates to a rotary 12-nozzle jet inline nozzle. Background technique [0002] The vacuum belt recycling wall-climbing robot is mainly used in the working condition of removing rust and paint on the steel surface. Its main components are permanent magnetic adsorption device, power system, vacuum recovery system, The rust and paint removal effect of the recycling wall-climbing robot mainly depends on the high-speed rotating nozzle installed on the cleaning plate; [0003] The rotary sprinkler refers to the sprinkler that can automatically rotate around its vertical axis and spray by relying on the water pressure during sprinkling irrigation. Most of the existing rotary sprinklers are large in size, with unreasonable nozzle structure design and poor spray effect.

[0003] The rotary sprinkler refers to the sprinkler that can automatically rotate around its vertical axis and spray by relying on the water pressure during sprinkling irrigation. Most of the existing rotary sprinklers are large in size, with unreasonable nozzle structure design and poor spray effect. At the same time, the spray pipe is somewhat The exposed design is easy to replace and maintain, but it is easy to oxidize when working for a long time under high water pressure, which will cause it to break or be damaged. Therefore, the present invention provides a rotary 12-nozzle jet- The glyph nozzle, through the threaded connection between the nozzle and the rotating shaft, and the interference fit connection between the deep groove ball bearings, angular contact ball bearings, magnetic components and the rotating shaft installed inside the shell, the nozzle can be rotated under the action of internal water pressure. The shaft rotates around the casing at high speed. At the same time, the pressure relief sink holes set on the left and right sides of the nozzle and the main water inlet sink hole are connected inside the nozzle, which can be adjusted by the plug cap to ease the flow of the main water inlet sink hole into the nozzle installation hole opened at the bottom of the nozzle. In addition, the nozzle can be easily fixed and installed through the water inlet connector to improve convenience; the design of the internal conduction structure can ensure that the internal water pressure is too large through the nozzle shell structure. Will not damage the nozzle, prolong the life of the nozzle
