Cone type nozzle with concentric circle dual pipe structure

摘要

The present invention more particularly relates to an ejector nozzle for mixing a small amount of drugs in large amounts of enemies In more related to more quickly cone nozzle having a concentric double pipe structure in which the drug can be mixed with the raw water ejector. ; cone type nozzles with a concentric double pipe structure according to the invention one ejector is provided with a double tube of the assembled structure to be inserted into the canal of the relatively large diameter of the tube of smaller diameter and arranged in a concentric cone using two different nozzle diameters to be installed in the pipe for the raw water flow pipe geotinde, the double tube, but the respective distribution of the drug and pressurized liquid body that the raw water miscible character to the two conduits arranged in a concentric circle formed by the hake a high pressure injection increases the hydraulic pressure of the pressure can be relatively small, the nozzle Mixing the raw water to be sucked out by the drug to generate a negative pressure at the tip. ; relative to the distal end of the inner tube of the double tube shorter than the tip of the appearance of the drug with a low-pressure hydraulic effectively sucked toward the enemy to come and to form, the drug is injected from the nozzle of the double tube structure, install the eductor venturi tube forms the anterior tip of the nozzle to be mixed effectively with the enemy.
